General Info

    Mechanicum
    --------------------------------------------------------
    - Mechanicum fleets sport greater variety in modified vessels:
    Spoiler
    “THE ADEPTUS MECHANICUS fleet that flew in a shoal around the Antithesis had been assembled on Mars. The Antithesis was a cruiser-class vessel, not quite the equal of one of the Imperium’s ancient mighty battleships, but a swift and well-crewed ship with enough Martian-forged armaments to punch above her weight. Her sister ship, the Constant, was slower and less manoeuvrable, but much more heavily gunned, and sported an enormous nova cannon on her prow that could blow an enemy cruiser clean in two. The Constant was under the command of Magos Hepsebah who trusted no one but herself to operate the nova cannon. Both craft were in the dark red of the Adeptus Mechanicus, with the half-steel skull of Mars worn as proud heraldry. Several armed explorator ships of the Asdepian Squadron flew a picket around the two cruisers. They were smaller craft, but theywere hardy, built for exploring harsh regions and for resisting the worst excesses of stellar radiation and micrometeorite impacts.They made for capable escort craft, tough enough to weather enemy fire and nimble enough to outfox slower enemies. They had been difficult for Voar to acquire since they had been destined to explore the Imperium’s Eastern Fringes. Magos Khrul, his spedaliry being the same kind of deep-space hostile exploration at which the squadron excelled, was in command.

    The light cruiser Defence of Caelano Minoris had been fitted out as a laboratory ship, its gun decks stripped out and replaced with medical labs and crucible chambers to research anything the fleet might find. A whole deck was sealed and gene-locked so it could be used for the study of alien artefacts. The Defence was the domain of Magos Crystavayne and Magos Devwyn. It usually flew in the wake of the Ferrous, an armed factory ship that wallowed obesely through space, dragging an enormous processing and storage section behind it, plumes of plasma fire bursting through the vents down its spine as it turned its cargo of harvested ore and chemicals into fuel for the rest of the fleet. Magos Vionel, the commander of the Ferrous, was as much a part of the ship as its chemical tanks and fusion chambers were.”
    Hellforged, p.21 & 22 - **

    - Powerful display for gravitic tractor beams:
    Spoiler
    “Alerted by the incredulous voice of one of his gunnery officers, Semper looked at the image on the augur screen, sharing the man’s disbelief.

    The Sabretooth was a wreck, its hull riddled with blast craters and torpedo wounds. Somehow, though, it continued to fight. Semper could only secretly marvel at the very orkoid inability to admit defeat as, in complete defiance of all the odds, the vessel’s commander managed to fire up manoeuvring thrusters and to crew to man the gun batteries.

    The vessel swung round in space, its side batteries sending out a wave of fire to crash explosively against theMacharius’s shields and hull. As it did, Semper could see the horrific damage so far inflicted on it. Through the gaping holes in its armoured skin, fires could clearly be seen burning inside its decks and compartments. As it continued to swing round, Semper could see the starfield behind it, visible through the holes blasted clean through its body.

    ‘Vandire’s oath,’ breathed Ulanti, standing beside his captain. ‘What’s keeping them going?’

    ‘Sheer bloody-mindedness, Mister Ulanti,’ replied Semper. ‘You can’t convince a greenskin that it’s truly dead until you hold up its severed head and show it its own bullet-riddled body.’

    The Macharius’s own gun batteries replied, blowing away more fragments of the unshielded target’s hull, but still the monster kept on moving. The dark maw of its prow mouth gaped open in threat, and Semper had a sudden and terrifying vision of the fate of theFea rsome.

    ‘Engage portside thrusters. Hard to starboard! Get us out of reach of that damned tractor beam!’

    There was that familiar, sickening lurch in the pit of the stomach as the ship swung round and the artificial gravity generators lagged a second or two behind in readjusting to the vessel’s new orientation. A further, this time reassuring, shudder ran through the ship as its engines fired up, taking it out of harm’s way. The sense of relief amongst the command deck crew was almost palpable.

    The elation did not last long. Semper was thrown to the ground as the deck beneath his feet vanished from under him. There was a crash from high above, and the jagged spear of a great, splintered stalactite of machinery crashed into the flag-stoned floor several metres away, crushing and killing a tech-priest and a junior ordnance officer.

    There was the scream of tortured metal from all around them, and the whole ship shook under a continuous series of violent, pounding impacts.

    Klaxons and warning alarms reverberated from dozens of points throughout the ship. Leoten Semper climbed to his feet, wiping away the blood from his face from a flying metal sliverthrown out by the falling machinery. There was a dry, foul taste in his mouth, and a sensation of sick dread in his heart. His ship, he knew, was now in the deadliest of perils.

    The internal comm-channels were filled with panicked damage reports from the intolerable strain now being put on the ship’s innermost structural integrity.

    ‘Hull breach… gun-deck three. Requesting permission to evacuate.’

    ‘Fires on decks eighteen, nineteen and twenty-one.’

    ‘Got a hull breach here on forward compartment, deck sixteen. Sealing blast doors now.’

    ‘Enginarium… serious coolant failure on Reactor Tertius… engaging emergency coolant systems.’

    ‘Open the blast doors… We’re trapped in here! Emperor’s mercy, we can’t get out!’ Semper gathered his wits. His ship was in pain, and could be destroyed any minute. ‘Mister Ulanti, what’s our situation?’ he barked.

    Ulanti’s face was grim. ‘Definitely still some life inSabretooth, sir. It’s sunk its teeth in, and now it’s trying to take a bite of us. A large bite, it would seem.’

    Semper cursed. A tractor beam, one of the few high technologies which the orks had managed to master for their own use. And, being orks, that use was as a weapon, of course.

    The Macharius was caught in the invisible grip of a huge and powerful ork tractor beam weapon mounted in theSabretooth’s mouth-like prow. The tractor beam wasn’t powerful enough to bodily drag or hurl theMacharius through space, as the orks had done with the asteroid missiles which had been directed at the Graf Orlok and which had smashed apart one of Vanguard squadron’s Cobra destroyers, but it was still easily capable of destroying the ship. The powerful gravitic forces of a tractor beam, recklessly manipulated in the right way, could be used to crush or tear apart a target, or at least a portion of a larger target.

    This was what was happening to the Macharius now. The tractor beam had seized a large hull section, and was attempting to tear it free from the rest of the ship. Less than half an hour ago, Semper and the crew of theMacharius had seen theFearsome ripped apart by Sabretooth’s savage tractor beam jaws. Now the same thing was happening to them. Semper could sense his ship starting to tear apart. Metal buckled. Armoured hull plates ruptured. Power conduits exploded or failed. TheMacharius screamed in torment at the intolerable strain being put upon its metal body.

    THE SOUNDS OF his ship’s distress continued, coming to him both over the command deck’s comm-channels and reverberating through the very substance of the ship. Semper knew the Macharius was only moments away from suffering irreparable damage. ‘Helm – all ahead full. Channel all available power to engines and get us out of this thing’s grasp.’

    ‘No!’

    It was the voice of Magos Castaboras, the most senior servant of the Machine God aboard theMacharius, who had just arrived on the command deck, surrounded by his customary train of tech-priest acolytes. Even with destruction looming, the officers and crewmen present stared in complete disbelief at this unforgivable challenge to a captain’s authority here on his own command deck.

    Semper stared at the impassive gold-masked face of the senior tech-priest. He had little fondness for the cold and aloof Castaboras. Few aboard theMacharius did, but he had no doubt of the man’s abilities, or his unsurpassed knowledge of the workings and capabilities of the vessel to which he had so far dedicated more than eighty years of his Machine God-extended life.

    ‘Explain!’ snapped Semper, as the sound of the ship’s torment grew louder all around them.

    The tech-priest spoke quickly but calmly, his voice offering little in the way of accent or human emotion. ‘If we engage the engines, we will only hasten our own destruction, struggling in one direction against the force pulling at us from the other, and tearing the ship apart in the process. However, there is another way…’

    The tech-priest’s last words were almost drowned out by the tortured shriek of metal on metal. Semper didn’t hesitate, knowing they likely only had seconds.

    ‘The Magos has command,’ he told his officers, doing what many captains would consider the unthinkable, even under such dire circumstances.

    Castaboras set to work immediately. ‘Engage port and starboard thrusters – anchor us in space. Channel all available power to the defence shields and set the shield frequency to four points above the norm.’ He broke off, favouring the officers of theMach arius with a rare explanation of his methods. ‘Studies have shown that changes in shield frequency can interfere with the gravitic fields of tractor beam weapons. I have never seen it done myself, but the great Magos Technicus Sulpicius the Precise proved in his studies in M.39 that—’Remus Nyder exploded in anger. ‘Look at the shield output readouts, man. You’re overloading the generators! And now you talk of ”studies”, and tell us that we’ve put the safety of the ship in the hands of the theories of some long-dead damn Machine God prayer babbler who none of us have even heard of!’

    Castaboras looked at Semper, directing his reply to him and ignoring Nyder. ‘The shields will hold, captain. I know this vessel. I tend to its workings. I commune with its machine-mind. I offer prayers to its sacred spirit. I have faith in its strength, and so too should you and your men.’

    The violent shaking took on a different timbre now. A tone of slightly anxious relief crept into the tech-priest’s voice.

    ‘It’s working. The shields are interfering with the tractor beam. They’re boosting the tractor beam’s strength, trying to keep their grip on us.’ He stepped back, taking firm hold of a nearby instrumentation panel. ‘I recommend you and your men hold onto the nearest fixed surface, captain. The venerable magos’s studies suggest that the final moment of uncoupling may be hazardous to a vessel’s human crew components.’

    There was a final scream of metal, matched by the shriek of energy generators overloaded to near destruction. Then, suddenly, the ship was moving, tumbling through space, rolling almost thirty degrees on its portside, its artificial gravity field crucially lagging several seconds behind in adjusting to the ship’s radical change of orientation as theMacharius was brutally expelled free of the tractor beam’s deadly grasp.

    Castaboras’s warning was well-founded. For a second, Semper found himself in freefall, falling laterally across the command deck, before the firm grasp of Remus Nyder found him and pulled him to safety. Semper nodded his thanks, and hauled himself to his feet. The command deck was still filled with the sound of warning alarms and comm-net distress calls. If anything, the flood of damage reports and distress calls had increased, as the ship took stock of the cost of that last near-disastrous manoeuvre. Still, Semper knew that at least now his ship was safe from imminent destruction.

    His ork opponents, however, had different ideas.

    The augur screen was cracked, the image on it temporarily flickering and indistinct, but Semper could still make out the flame-wreathed shape of the ork cruiser as it laboriously swung round in space in pursuit of them, presenting its lethal tractor beam maw towards them once more.

    ‘It’s still after us!’ shouted a young surveyor adept in near panic. ‘It’s powering up its tractor beam for another attack!’

    ‘No, it’s not,’ said Semper in determination, looking towards Remus Nyder. ‘Mister Nyder, what do we have in the way of torpedoes?’Nyder checked the information on the data-slate handed to him by one of his junior officers.

    It made for grim reading. ‘Only two in the pipe, captain. It’s a hell of a mess down there, I’m told. That last jolt really shook up our torpedo room. I’ve got two tubes out of action, half my loading crews dead or injured and Emperor only knows how long before we can get the other two tubes loaded and ready to fire.’

    Semper looked at the auspex screen, checking the telemetry data scrolling down the sides of the screen and making his own personal calculations about the angle of fire, the closing distance between the two vessels, the current battle status of each of them and the likely outcome of any head-on battle between them. The answer he came up with was not much tohis liking, but he was a captain in His Divine Emperor’s Navy, and so it was not in his nature to show any sign of fear or weakness on his own command deck and before the eyes of his expectant crew.

    ‘Two torpedoes will be more than enough,’ he said, in a voice filled with more confidence than he felt. ‘Helm – bring us around. Ordnance – prepare to fire as soon as you have a good angle of shot.’

    The ship’s manoeuvring thrusters fired again, bringing it round to face the oncoming Sabretooth. To the watching crew on the command deck, it seemed to take the prow an eternity to swing through the sixty degree angle which would bring the ship round towards the enemy ship.

    All the time, theSabretooth came on. In the minds of some of the more nervous crewmen aboard the command deck of theMacharius, the ork cruiser’s open maw with the tractor beam weapon hidden inside seemed to gape open to swallow up the entire ship.

    Light flared within that maw. ‘Power levels are building,’ reported a surveyor adept. ‘They’ll be activating that thing any second now.’

    ‘In position. Target in range. Angle is good,’ reported an ordnance officer a second later.

    ‘Fire torpedoes!’

    The words were barely out of Semper’s mouth before he held the dull roar of the torpedoes’ release from their prow silos. The missiles streaked through space towards their target. Light flared stronger between theSabretooth’s jaws. Aboard theMacharius, they felt the first shifting lurch as the tractor beam’s gravity field once again took hold of the ship.

    The torpedoes shot between the metal jaws. For a moment, it almost appeared as if the Sabretooth had actually swallowed them, and even the most resolute of veteran navy officers watching felt a moment of sickening fear, as it seemed that almost nothing could destroy the vessel. Sabretooth’s head exploded. It keeled over, tumbling away through space, a series of secondary explosions gutting what was left of its shattered innards. ‘Double impact. Target destroyed,’ recorded the surveyor adept.

    ‘Scan the area,’ ordered Semper. ‘Surveyors and augurs to maximum. Search for any remaining enemy vessels.’ He waited impatiently while his orders were carried out, servitors and tech-priests attuning themselves to the massive flood of information gathered by the ship’s electronic senses and sifting through it in search of any further threats. Finally, the answer came back from Hito Ulanti, the second-in-command confirming the scan findings relayed onto the screen of his control lectern.

    ‘No enemy vessels found within surveyor range. The garden is clear, captain.’ For the first time in hours, Semper allowed himself to relax. The battle for the Mather system was over.”
    Shadow Point, p.63 - **

    - Imperial sensors:
    Spoiler
    “Semper looked down at the technical data scrolling across the slate’s viewing plate, and frowned. ‘These frequencies are extremely low-level, and the prime fluctuation vector you’re suggesting in these equations is extremely unorthodox. The Despoiler’s vessels aren’t too dissimilar to our own, with a broadly similar power output signature. Anything two or more ratio levels above these figures is enough to detect anything, friend and foe alike, within a radius of at least three AUs.’

    ‘Indulge us, commodore,’ smiled Horst.

    Semper nodded curtly to his surveyor officers, who immediately set about making the necessary adjustments to their instruments.

    ‘The surveyor devices will take some moments to match the recalibrated settings we have introduced into them,’ warned Monomachus. ‘In the meantime, it would be best if…’

    He broke off, looking meaningfully towards Horst.

    ‘Tell your crew to be prepared, Semper,’ said Horst, taking up the warning. ‘Tell them that, no matter what appears on their auspex screens, they are to take no offensive action of any kind. You can consider this a command backed by the full authority of the Emperor’s Inquisition.’

    ‘And what exactly are you expecting to find out here, inquisitor?’ asked Semper, refusing to be intimidated on the bridge of his own vessel by anyone, even a senior inquisitor.

    Horst did not immediately answer. A few moments later, one of the junior gunnery officers did it for him.

    ‘Throne of Earth! There, eighteen thousand kilometres to our starboard rear. Vandire’s teeth, they’re practically staring right up our arse!’

    A loud babble of exclamations and oaths from tech-adepts and surveyor officers quickly confirmed the sightings. Semper looked at the data-images suddenly appearing on the augur screens all round the command deck. He kept his composure, but it took all his will not to react in the way which his every command instinct compelled him to.

    Eldar vessels. Three of them, all easily within striking distance of the Macharius and its sister ships.”
    Shadow Point, p.85 - **

    - Dark Eldar cloaking surpasses Imperial system-wide sensors:
    Spoiler
    “Somewhere else within the Stabia system, hidden vessels watched and waited. They hid in shadow, cloaked from the senses of the other vessels, even those of the eldar ships.” Shadow Point, p.86 - **

Energy Output

    Hellfire Missiles
    --------------------------------------------------------
    - Each missile may yield a total of 610 gigatons of energy:
    Spoiler
    “Four Gothic-class cruisers–Intolerable, Invincible, and Righteous Force–awaited four parsecs from target. Each ship carried 100 Hellfire nuclear missles. Each missle 122 warheads, each with a firepower of 5 GT. If boarding action fails, nuclear missles will turn a ship to dust.” Space Hulk Rulebook, p.3 - Scenario Book


    Torpedo Launchers
    --------------------------------------------------------
    - Launch powerful plasma bombs:
    Spoiler
    “A typical anti-ship torpedo is over 200 feet long and powered by a plasma reactor, which also acts as a sizable portion of its warhead, turning it into a devastating plasma bomb.

    Once a torpedo is launched, the plasma drive propels the torpedo forward at high speed, whilst beginning an energy build-up which will culminate in its detonation. Torpedoes have a limited ability to detect a target and will later course to intercept if they pass within a few thousand kilometers of a vessel.”
    Battlefleet Gothic Rulebook, p.28 - **

    - A single salvo incinerates a planet's entire atmosphere for a month:
    Spoiler
    “A sleek Inquisitorial corvette under the command of Inquisitor Baptiste fired a single salvo of torpedoes at the planet, a deadly payload of atmospheric incinerators. The warheads ignited the oxygen-rich atmosphere of the planet, devouring everything in a blistering conflagration that seared all life from the world, turning metal to molten slag and rock to glass as the Inquisition's fiery judgement took its toll. The planet burned brightly for a whole month, and from the safety of their world, the inhabitants of Medusa V looked on in awe as their neighbor was consumed in purifying flames.” The Fall of Medusa V, p.13 - **


    Weapon Batteries
    --------------------------------------------------------
    - Imperial batteries combine a varied array of weapon types:
    Spoiler
    “Weapons batteries form the main armament for most warships, ensuring that much of their hull is pock-marked by gun ports and weapon housings. Each battery consists of rank upon rank of weapons: plasma projectors, laser cannons, missile launches, rail guns, fusion beamers and graviton pulsars. Weapons batteries fire by salvoes, using a co-ordinated pattern of shots to catch the target in the middle of a maelstrom of destruction.” Battlefleet Gothic Rulebook, p.20 - **

    - Multiple decks may fire in succession:
    Spoiler
    “The decks fired one after the other, the gun-crews of every level firing almost as one, throwing an inescapable barrage of plasma shot, graviton pulses, magnetic cores and fusion missiles into the face of the closing ship. Its prow cracked as the payloads struck true, and then it shattered into pieces, the following salvoes exploding layer after layer.” Relentless, p.137 - **

    - Have awe-inspiring power:
    Spoiler
    “The majestic form of the Vae Victus slowly angled its massive bulk towards the surface of Pavonis, powerful energies building in her forward linear accelerators. Few men knew the awesome power of destruction the captain of a starship possessed; the power to level cities and crack continents.” Nightbringer, p.161 - **

    - Have terra-watt beam weapons amongst many others:
    Spoiler
    “Starships weapons in the 41st millennium are as varied as the ships that carry them. Lasers, plasma projectors, macrocannons, rocket launchers, terra-watt beam weapons, and more esoteric weaponry such as grav-culverins and gamma emitters, all can be found in a starship’s braod side. In game terms, the weapons found in rogue Trader can be divided into two distinct classes; macrobatteries and lances.” Rogue Traders, p.128 - **
Range
- An Astartes Battle Barge lays waste to Orks from orbit:
Spoiler
“Nestor looked up into the grey sky. Even without the cloud, he would have been able to see nothing of the Dark Angels battle-barge manoeuvring into firing position hundreds of kilometeres above. The Unrelenting fury would be dipping down towards Piscina's atmosphere, rotating about its axis to bring the dorsal bombardment cannons to the correct angle. Shells the size of buildings were being loaded into massive breeches - much of the size and weight was ablative shielding that would melt away during entry into the planet's atmosphere - while armoured turrets like small city blocks turned slowly into position.

The first salvo appeared as two blurs barely visible through Nestor's darkened autosenses. They streaked groundwards, punching out of the cloud at ultrasonic speed. The warheads had been set to airburst, exploding fire hundred meters above the Orks, two kilometres from the defenders of Koth Ridge. Two stars burst into life against the darkened vista. Even through the filter of his autosenses the blossoms of plasma were bright enough to make Nestor's surgically improved eyes water. The explosions scorched the sky, raining down fire, a shockwave advancing ahead of a sheet of flame, obliterating everything in its path. Molten destruction rained down on the Orks, consuming a swath of the advancing Greenskins in a bright conflagration. Nestor heard the strangely high-pitched shrieks of the Orks; the cries of blinded troopers too stupid to have heeded Sarpedon's warning; an ear-splitting crack of air and water molecules being ripped apart.

An area half a kilometre across was devastated in three seconds, shattered rocks turned to glass, Orks reduced to a have of ash and dust, patches of grass and stands of bushes no more. Two overlapping smooth sided craters were all that remained of the hundreds of Orks that had been beneath the twin detonations.”
The Purging of Kadillus p.136 & 137 - **


    Torpedo Launchers
    --------------------------------------------------------
    - Display ranges in excess of 75,000 leagues:
    Spoiler
    “The two Blackstones have taken up station five thousand leagues from each other, some seventy five thousand leagues from Fularis II and just out of range of the weapons platforms, except for the torpedo launchers.” Battlefleet Gothic Rulebook, p.97 - **

Ship Payloads

    Cruisers
    --------------------------------------------------------
    - Cruiser weapons awe guardsmen:
    Spoiler
    “Their anti-ordnance defence turrets have weapons larger than those carried on Titans, their barrels over ten metres long, dozens of the point-defences studding the hull of a ship the size of a cruiser. Their broadsides vary, sometimes having huge plasma cannons capable of incinerating cities, other times it's mass drivers that can pound metal and rock into oblivion. Short-range missile batteries can obliterate a smaller foe in a matter of minutes, while high-energy lasers, which Jamieson tells me are called lances, can shear through three metres of the toughest armour with one devastating shot. Most cruisers carry huge torpedoes as well, loaded with multiple warheads charged with volatile plasma bombs, carrying the power to unleash the energy of a small star on the enemy. It makes my humble laspistol look like a spit in an ocean. More like a hundred oceans, actually.” 13th Legion, p.134 & 135 - **

    Spoiler
    “Every weapon in the warship's arsenal was prepared and oriented down at the surface - torpedo arrays filled with warshots that could atomise whole continents, energy cannons capable of boiling off oceans, kinetic killers that could behead mountains through the brute force of their impacts.” Nemesis, p.375 - **

Various quotes on Imperial vessel numbers & weapons from the new Rogue Trader: Battlefleet Koronus rulebook and a few others.


Spoiler
Gunnery crew sizes

"Engines and reactors of a warship occupy a third of its mass; gun decks usually constitute three quarters of what remains. Even individual macroweapons are giant, house-sized affairs covered with gantries, cranes, power lines and pipes with a crew hundreds strong. Lance turrets are even bigger - the size of a city block with a crew numbering in the thousands." - Rogue Trader: Battlefleet Koronus, Pg. 48 - The Imperium's Shield: The Birth of a Warship


Torpedoes

"Gryphonne-pattern Torpedo Tubes
The most common template used for destroyers, raiders, and other smaller missile boats is the Gryphonne pattern. They are most always mounted as a primary prow weapon. This Component is capable of firing four torpedoes in each salvo. It can store 24 torpedoes, plus an additional four if the ship's captain does not mind keeping four 'in the tubes.'"
- Rogue Trader: Battlefleet Koronus, Pg.37 - The Weapons of War: Additional Components

"Mars-pattern Torpedo Tubes
Larger vessels are capable of supporting far more massive installations of torpedo tubes. In addition to a larger ammunition capacity, these Compnents are also capable of firing six torpedoes in each salvo. It can store 42 torpedoes, plus an additional six if the ship's captain does not mind keeping six 'in the tubes.'"
- Rogue Trader: Battlefleet Koronus, Pg. 37 - The Weapons of War: Additional Components

"Plasma warheads
These explosives are the standard armament for Imperial torpedoes. These systems are designed to blast through a spaceship's armoured hull, using their high speed to punch deep into the target vessel. The plasma reactor that powers a torpedo's drive forces it deep into the bowels of the ship and then overloads, contributing to the fury of the warhead's detonation. This reduces complexity, making their manufacture comparatively simple. Thus, these torpedoes are the staple of Imperial Navy warships."
- Rogue Trader: Battlefleet Koronus, Pg. 8 - The Weapons of War: Torpedoes

"Melta warheads
These weapons are even more feared by starship captains than standard torpedoes. Mercifully rare and extremely brutal, melta warheads detonate a precisely-organised series of melta charges upon impact with a target, burning through hull plating and consuming sections of the vessel's interior in a roiling conflagration."
- Rogue Trader: Battlefleet Koronus, Pg. 8 - The Weapons of War: Torpedoes

"Virus warheads
In cases when a vessel must be captured intact, but the target's crew are considered expendable, virus warheads are considered an ideal solution. Pirates more interested in inert cargo, salvage, and the possibility of expanding their fleet lust after these rare and unstable armaments."
- Rogue Trader: Battlefleet Koronus, Pg. 8 - The Weapons of War: Torpedoes

"Vortex warheads
Only a few remaining Forge worlds still maintain the technological craftsmanship to manufacture these rare weapons. The Vortex Warhead is not a crude explosive charge, but an arcane device thar tears open a rent in the very fabric of reality, consigning vast chunks of its target to the warp. The swirling energy within this tear in the fabric of reality immediatly draws all matter in its blast radius through it, leaving gaping wounds in the target vessl."
- Rogue Trader: Battlefleet Koronus, Pg. 8-9 - The Weapons of War: Torpedoes


Macrocannons

"Disruption Macrocannons
This macrocannon variant fires a "shell" of highly charged, ionized deuterium atoms. These particles cause minimal physical damage to their targets. Instead, they are intended to overload and shut down power transfer systems throughout the target vessels. These weapons are particularly useful for vessels that need to capture their prey intact."
- Rogue Trader: Battlefleet Koronus, Pg. 34 - The Weapons of War: Additional Components

"Hecutor-pattern Plasma Battery
The Hecutor Pattern plasma battery is an ancient variant of plasma macroweaponry that refocuses the power of the plasma 'blast,' concentrating it into a compressed photonic packet that can be fired over extremely long distances. It is rare to see these on any but the oldest vessels, meaning many are found on heretic vessels lost to the forces of Chaos millennia ago."
- Rogue Trader: Battlefleet Koronus, Pg. 34 - The Weapons of War: Additional Components

"Stygies-pattern Macrocannon Battery
This variant of the macrocannon is designed to fire heavier ordnance than the Mars Pattern. These alternative shells contain an adamantium core that cuts through the heaviest armour.
- Rogue Trader: Battlefleet Koronus, Pg. 34 - The Weapons of War: Additional Components


Nova Cannons

"Nova Cannons are a classification of exceptionally powerful weaponry that can only be mounted upon capital ships. Mounted below the heavily armoured prows of Imperial Navy cruisers and battleships, Nova Cannons have few equals in terms of thier range or destructive power. While variation exists, a typical Nova Cannon consists of an array of potent gravimetric impellers designed to accelerate a projectile to a fraction of the speed of light. These projectiles vary more than the nature of the cannons themselves, ranging from sophisticated plasma warheads which burn with the ferocity of a small star for a fraction of a second, to implosive devices which exert destructive gravitational forces upon all those caught within several thousand kilometres of the detonation. In any case, a well-used Nova Cannon is a terrifying thing to face, as much a psychological tool as a weapon." - Rogue Trader: Battlefleet Koronus, Pg. 15 - The Weapons of War: Nova Cannons


"Mars-pattern Nova Cannon
Though Nova Cannons are quite rare, even by standards of starship construction, the Mars pattern is the most common construction template. These massive cannons - hundreds of meters in length - fire an enormous shell that echoes a traditional explosive shell, though on a much larger scale. These shells are accelerated to near relativistic velocities, causing an explosion that detonates with more force than dozens of plasma warheads."
- Rogue Trader: Battlefleet Koronus, Pg. 36-37 - The Weapons of War: Additional Components

"Ryza-pattern Nova Cannon
This variant replaces the massive explosive shells with a highly unstable plasma-based macro-bomb. These weapons are even more power-hungry than a Stygies pattern, but are believed to be slightly more effective as well. With this additional power does come some additional questions of stability, as weaponising such huge quantity of plasma carries its own danger."
- Rogue Trader: Battlefleet Koronus, Pg. 37 - The Weapons of War: Additional Components

"Jovian-pattern Nova Cannon
One of the rarest of all Nova Cannons, the Jovian pattern replaces the explosive shells with vortex warheads. The resultant rifts into the warp have been known to rend target vessels cleanly in half."
- Rogue Trader: Battlefleet Koronus, Pg. 42 - The Weapons of War: Additional Components


Other stuff

"Minelayer Bay
An often-used tactic among pirate fleets is to strew a heavily-trafficked shipping lane with mines, and then pounce on any unfortunate ship cippled by their massive explosions. Starship mines are huge and can explode with catastrophic effect. Most are automatically triggered via an on-board passive auspex to home in on nearby vessels, but some can be remotely operated to achieve greater effectiveness. For starships plying common transit lanes through a systems, they are a frequent worry that requires constant vigilance."
- Rogue Trader: Battlefleet Koronus, Pg. 38 - The Weapons of War: Additional Components


"Field Bracing
The ship's hull and structural supports are ribbed with power-field generators, which can greatly reinforce the vessel's structual integrity as long as they are powered."
- Rogue Trader: Battlefleet Koronus, Pg. 38 - The Weapons of War: Additional Components


"Power Ram
Whereas some traders desire the obvious intimidation of a huge armoured prow, others prefer a more subtle approach and sheath an otherwise unremarkable ram beneath their ship's prow with power-field generators. When activated, the ship's ram glows with hazy light and is often the last thing an enemy captain will see before impact."
- Rogue Trader: Battlefleet Koronus, Pg. 38 - The Weapons of War: Additional Components




Fleet sizes

"Hololithic green triangles appeared above her cloud-masked surface. These were the orks’ ships at anchor in high orbit. There were still thousands of them. Deguerro directed Kantor’s attention to the orbital plane of the Rynn star system’s outermost planet, Phraecos, a barren, moonless world with a surface of frozen methane. Just within the hololithic ring of the planet’s orbital path, a formation of glowing blue triangles flickered into existence, attendant streams of digital data spooling through the air beside them. 'Two thousand two hundred and sixteen warp-capable ships,' said Deguerro, 'and nothing smaller than a Dauntless-class light cruiser. There are several Space Marine battle-barges, but the main bulk of the fleet’s firepower is comprised of that aboard the Imperial Navy’s Emperor and Retribution class battleships. There are four each of these, a significant commitment from Segmentum Headquarters.' Kantor looked again at the swarm of triangles representing the orks fleet around Rynn’s World. He thought for a moment, then said, 'This Imperial force is enough to break through and land troops, but it is not enough to eliminate the enemy fleet outright.' 'True,' said Deguerro. 'But we have been assured that further support is on the way.'" - Rynn's World, Pg. 198-199



Exterminatus

"The Night Lords' ships orbited Nostramo, hundreds of weapons trained on the shrouded planet, the rays of the system's dying sun glinting from barrels too numerous to count. As the fabric of space buckled and twisted, disgorging the few craft able to keep pace, the lances and mass drivers of Night Haunter's flagship opened fire upon the planet.
Beam after beam of incandescent light joined the fusillade, all concentrating upon the same point, a weak spot in Nostramo's adamantium crust theorised to be left by the Primarch's initial landing. The lasers of the Night Lords' ships focused a blinding lance of pure energy into the planet's core, and with a cataclysmic explosion, the dark planet burst apart."
- White Dwarf #259 (August 2001), Pg. 60 - Index Astartes: Night Lords

"There are many forms of Exterminatus, and many ways of delivering it. One method uses a biological agent that renders all living matter to a decayed sludge within hours, releasing a staggering amount of oxygen into the atmosphere as it does so. This oxygen is then burnt off, igniting the entire atmosphere and incinerating everrything on the surface. Another method involves the use of cyclonic torpedoes, a category of weapons that use varying means of scouring the world's surface with nucleonic fire, raw plasma, or deadly radiation. Some worlds might be virus bombed - sometimes the viral agents might be keyed to a specific gene code, so as to target aliens, mutated humans, or simply rebels with a predominant hair colour.
Exterminatus may only be orderd by the very highest level of authority, and any who enact it will be answerable to the High Lords of Terra. While raw manpower remains the Imperium's greatest asset, worlds are not so easily replaced, and those who squander such resources seldom remain in power long enough ot make the same mistake a second time."
- Tactica Imperialis, Pg. 66

Void Shields shunt attacks into the Warp.

Spoiler
"The eldar ships glimmered with holofields, appearing as shimmering ghosts to open fire before disappearing against the star-filled backdrop. Human void shields sputtered with blue and purple flares as they unleashed bursts of energy to shunt the attacks of the eldar into warp space." - Path of the Warrior, Pg. 165

Orbital bombardment

Spoiler
"Below the world burned too. The fleet's bombardment had torched Prospero, and ignited the atmosphere. Spiral patterns of soot and particulated debris thousands of leagues across cycled like hurricanes. Giant columns of plasma energy had roasted all vegetation and wildlife, and turned the seas into scalding banks of steam and toxic gas. Vast las bombardments from the heavy batteries had evaporated river deltas and flash-thawed ice-caps. Kinetic munitions and gravity bombs had fallen like Helwinter hail, and planted new forests of bright liquid flame that sprouted and grew, spread and died back, all in a few minutes. Shoals of targeted missiles, silver-swift as midsummer fish running from a catchers net, delivered warheads that blasted the soil into the sky and thickened the air into poisonous soup. Magma bombs and atomics, the godhammers, had altered the geography itself. Mountains had been levelled, plains split, valleys thrown up into new hills of rubble and spoil. Prospero's crust had fractured. We saw the throbbing, glowing tracks of its mortal wounds, brand new canyons of fire that split entire continents. This was the grand alchemy of war. Heat and light, and energy and fission that transformed water into steam, rock into dust, sand into glass, bone into gas. Swirling mushroom clouds, as tall as our Aett on Fenris, punctuated the horizon we rushed towards." - Prospero Burns, Pg. 346



Spoiler
"A bombardment had begun, and the people of Dagonet’s capital feared it was the end of the world.
They knew so little of the reality of things, however. High above in orbit, it was only the warship Thanato that fired on the city, and even then it was not with the vessel’s most powerful cannons. The people did not know that a fleet of craft were poised in silence around their sister ship, watchful and waiting. Had all the vessels of the Warmaster’s flotilla unleashed their killpower, then indeed those fears would have come true; the planet’s crust cracked, the continents sliced open. Perhaps those things would happen, soon enough — but for now it was sufficient for the Thanato to hurl inert kinetic kill-rods down through the atmosphere, the sky-splitting shriek of their passage climaxed by a lowing thunder as the warshots obliterated power stations, military compounds and the vast mansion-houses of the noble clans. From the ground it seemed like wanton destruction; from orbit, it was a shrewd and surgical pattern of attack."
- Nemesis, Pg. 417-418


The Nemesis quote under Ship Payloads isn't entirely accurate. This one is word for word from the novel.
Spoiler
"Every weapon in the battleship's arsenal was prepared and oriented down at the surface - torpedo arrays filled with warshots that could atomise whole continents in a single strike, energy cannons capable of boiling off oceans, kinetic killers that could behead mountains through the brute force of their impact. This was only the power of the ship itself; then there was the minor fleet of auxiliary craft aboard it, wings of fighters and bombers that could come screaming down into Dagonet’s atmosphere on plumes of white fire. Swift death bringers that could raze cities, burn nations." - Nemesis, Pg. 375

Warp torpedoes

"The battle-barge shuddered as the gigantic missiles were launched. They appeared instantly on the screen, four flares of yellow plasma against the stars that suddenly winked out of existence as their warp drives engaged.
Skipping in and out of warp space, the torpedoes left a trail of multicoloured flashes in their wake describing an arc that slowly curved to the right as the Salamanders craft tried to evade them. Then they were out of sight, reduced to warp-echo registers on the scanners.
Twelve thousand kilometres to target, reported a weapons officer, reading from a glowing green screen.
He was Skanda Vior, a World Eater too, and like Delerax and Kordassis was clad for battle in his armour. Unlike the officers, he had painted much of his armour red, a growing trend amongst the legion, an acknowledgement of Angron's warrior cult. Vior waited a few seconds.
Eleven thousand kilometres to target.
The countdown continued and Delerax ceased his pacing at seven thousand kilometres.
Six thousand kilometres to target said the weapons officer. Switching to inboard data scanners, preparing for spread. A sub-screen flickered into life on the main viewer, showing an aggregate view from the torpedoes, rendered in a stark black and red monochrome. Strange shapes whirled and Delerax realised they must have switched view while the torpedoes were in mid-jump.
A moment later they rematerialised in the real universe and the strike cruiser flashed into view.
It was long and thin, with a launch bay built on it's dorsal superstructure. Pinpricks of plasma erupted like sparks from the flight deck as Salamanders launched attack craft to intercept the incoming torpedoes.
Five thousand kilometres spread launch, announced the officer.
The torpedo-generated image swirled into static for a few seconds as the missiles separated, each disgorging four hundred warheads at the Salamanders cruiser.
When the relay returned the view was filled with a cloud of sixteen hundred glimmering projectiles. Explosions blotted out the stars as the Salamanders craft swooped and climbed and rolled through the mass, blasting away with cannons and lasers. As the warhead launchers continued to power towards the strike cruiser - each containing a five megatonne nuclear charge - the defence turrets of the Salamanders vessel opened up. Ripples of plasma blasts and flashes of high velocity munitions streaked across the view, detonating even more of the warheads.
The torpedoes were close enough now to relay a direct image. The construct-based picture was replaced by a near real time view of the strike cruiser. It was dark green and banded with broad irregular stripes of yellow, the badge of the legion visible against a huge white circle near it's prow. Through the haze of detonations, it turned away, the captain trying to narrow the ship's profile against the swarm of incoming warheads. Plasma engines shone like stars through the fog of explosions, distorted by a shimmer of energy fields.
Fool said Delerax smiling at the weapons officer. A rudimentary mistake. One should turn into a torpedo attack, protecting the engines. A novice, no doubt.
Blue and purple lightning flickered as the remaining warheads, several hundred of them, slammed into the strike cruisers shields. The vessel was engulfed by a blaze of detonations, so bright it appeared in the main display like a nova being born. More explosions followed as shields overloaded and the remaining warheads struck the cruiser's armoured hull. Plasma billowed from ruptured engine duct.
A moment later the mini screen vanished as the warhead launchers detonated.
Scanners confirm severe engine damage and moderate damage to the starboard gunnery decks.
Signal the flotilla, close in for the kill, replied Delerax."
