这就是一百多艘舰船的所有武器——包括宏炮、光矛、旋风鱼雷、新星炮以及更多——同时齐射发生的事情。
原文：The fire came to burn the void. Morethan a hundred ships opened up with every weapon. Macro-cannon batteries, ranksof lances, nova cannons, cyclonic torpedoes and more unleashed the anger ofhumanity against the obscenity before them. The raging of the Ruinstorm fadedbefore the searing light of purest, purging destruction. It was an act of waron a scale that had never been witnessed before. If there had beenremembrancers aboard any of the vessels, they would have felt compelled torecord an event so monumental in song and in verse.
The barrage struck the fortress, and then it did not matterthat there were no remembrancers. The action would not be remembered. Therewould be no songs. The immense became the insignificant. The explosions thaterupted on the face of the battlements lit up the view in the InvincibleReason’s oculus. But the Lion made the mental adjustment, and understood howtiny the site of the impact was in relation to the wall as a whole. It might aswell have been invisible, a momentary glint on the brass. We aren’t trying todestroy the barrier, he reminded himself. We need to pass through it. That isall. The flare of the blasts faded. Geysers of molten metal extended into thevoid. Burning gas dissipated. A crater as wide as the fleet appeared. It glowedfrom the heat of its creation. ‘Our auspex readings put the depth of the breachat approximately four thousand miles,’ Guilliman said.
计算：
这里要么是熔化要么是蒸发。这里我就按照蒸发来算。
4,000英里 = 6,437.376公里
所以半径是3,218.688公里
圆周率 × 3,218.688^2 × 6,437.376 =209,515,670,426立方公里
所以体积是2.095156704268*10^26立方厘米
目前公认的蒸发一立方厘米铁所需的能量应该是60,915.7焦耳。
2.09515670426*10^26 * 60,915.7 = 1.2762794*10^31焦耳
但是用于熔化或者蒸发金属的能量仅仅只是很小的一部分，因为要把道路清空，就意味着原本那些金属被熔化变成的液体或者被蒸发变成的气体还要被扬出去。根据原文，爆炸结束之后那个大洞就已经出现了，所以金属被爆炸带离原本位置所用的时间应该就是数秒之内，这里保守一些则可以算作十秒。这些气体和液体被推出去的时候肯定不会挤成一团，所以要让全部金属都不碍事儿，那么这些金属至少要被扬到堪比圆柱直径的距离开外，也就是6437.376公里之外。这样，我们就能够得到速度——每秒6.44*10^5米。
铁的密度是每立方厘米7.874g，代入前面的体积大小就能够得到1.65*10^24千克的质量结果。
根据动能公式，我们就可以用速度和质量算出能量，最后得到3.42*10^35焦耳的结果，这个结果换算一下的话就是8.17*10^25吨TNT当量。
结论：
3.42*10^35焦耳 或 8.17*10^25吨TNT当量

帝国一个亚星区的首都星球是一颗没有天文卫星的行星，而它的五个拉米伊级星堡就充当了天文卫星的角色。该星球表面的七成都被巢都构造覆盖。
原文：Thracian Primaris, capital world of the Helican sub-sector, seat of government, Helican sub-sector, Scarus sector, Segmentum Obscurus.
(…)
It has no moons, no natural moons anyway. Five Ramilies-class star-forts hang above its atmosphere, their crenellated towers and buttressed gun-stations guarding the approaches to and from the capital world.
(…)
Seven-tenths of its surface are now covered by hive structures, including great sections of the world’s original oceans. City-sprawl fills and covers the seas, and the waters roll in darkness far beneath.
- Eisenhorn Omnibus: Malleus

作者推特问答表示拉米伊级星堡直径三千多公里

帝国的舰队能够从与行星系平面垂直的方向发动进攻。其中的星堡能够从星瀑中取出恒星核心碎片，并且拖着它甩出去轰击对面的固定目标。考虑到恒星核心的密度和温度，碎片中的每一立方米都会有数亿亿焦耳（也就是千万吨级TNT当量）的能量，每一立方公里都是数十亿亿亿焦耳（也就是亿亿吨级TNT当量）的威力。
而星堡作为尺寸动辄上百公里、实体宇宙中能加速到75%光速的大型构造，需要由它拖行并且开到最大功率才能堪堪甩出的恒星核心碎片也会有着巨大到恐怖的体量，再加上行星系里面的一大片防御系统都被强光晃到无法定位舰队，这块核心保守估计也会有数十乃至数百公里的直径。这就会带来堪比地球重力结合能的威力。
原文：On 3117913.M41 the Loyalist assaultarmada entered Realspace in the Badab system, high up on the vertical plain ofthe planetary system, directly on an attack course for Badab VI.
(…)
At its vanguard was the Raptorus Rex, behind which, thanksto the artisanship of the Magos of Angstrom, was towed a burning stellar corefragment torn bodily from the Bale Cascade.
(…)
Swiftly reaching terminal velocity, the ponderous cyclopeanbulk of the Raptorus Rex engaged its main drive at maximum power to altercourse, straining against inertia to allow the hellish fire of the stellarfragment to pass it by on its collision course with the Sentinel-Sigma battlestation, while the Loyalist armada fell into a spearhead formation a safedistance behind.
- Imperial Armour 11

帝国能够在较为重要的任务中牺牲掉上千个拉米伊级星堡。比如，下文中这次任务就导致帝国损失了超过1200台已经服役了一万年的拉米伊级星堡。
原文：This operation, always perilous, hasresulted in the loss of over twelve hundred Ramilies Star Forts in their tenmillenia of service to the Emperor.
- Battlefleet Gothic: Planet Killer
考虑到这种牺牲对整个帝国而言似乎并不是很重要，所以拉米伊级星堡的数目其实并不少。

一艘非战舰的小船进入了行星的卫星轨道之后开始加速，并且在进入大气层的时候已经达到40%光速，并且原文明确这远不是它的最大输出功率（也就是加速度）以及速度。经过简单的推算之后，带入数十万公里的距离（如果考斯的卫星距离不和地球差太多的话）以及末速度，我们就能够得到上百万G甚至数百万G的平均加速度。这也符合上一条那个在片刻之间加速到四分之一光速的描述。
原文："The Campanile accelerates. Itlights its main realspace drives, delivering main extending thrust in aposition where it should be almost coasting at correction burst only. It raisesits void shielding to make itself as unstoppable as possible. It fires itselflike a bullet at the planet Calth.
The screams of its crew can still be heard, but no one islistening.
Main extending thrust is a drive condition used forprincipal acceleration, the maximum output that takes a starship to the brinkof realspace velocity as it makes the translation to the empyrean. It is acondition that is used as a starship moves away from a planet towards thenearest viable Mandeville Point, a distance that is roughly half the radius ofan average star system.
There is no such long run-up here. The Campanile is alreadyinside the orbit of Calth’s satellite. There is not enough range for it toreach anything like maximum output or velocity. Even so, it is travelling atsomething close to the order of forty per cent of the realspace limit as itreaches the edge of the atmosphere. It is travelling too fast for anythingphysical, such as an eye or a pict-corder or a visual monitor, to see it. It isonly visible to scanning systems and sensors, to detectors and auspex. Theyshriek at its sudden, savage, shockwave approach."
- Know no Fear
下文能够表明这是一艘非战斗性质的小船。文中强调这是舰队中的供给船。
原文：The fleet tender Campanile is mob-boardedand taken off the Tarmus Apogee approximately one hundred and thirty-six hours[sidereal] before count start as a preliminary to the Calth assault.
- Know No Fear
后面则是强调了它是一艘小船。
原文：Precise details of the circumstancessurrounding the loss of the Campanile are lost and alone in such darkness, on adeceleration arc past the outer moons, one small ship, overweight and wheezing,over three and a half thousand souls.
- Know No Fear

帝国舰船战斗时的巡航速度兼攻击速度就能够达到至少75%光速。
原文：“For the second time in less than anhour, space tore open. The reality fissure leapt and crackled like a luminouscephalopod, lashing tendrils of warp energy into real space that twisted out,fizzled and faded. Non-baryonic light flared brilliantly through the tear,backlighting the arriving ships. Monumental silhouettes, they were shot forwardinto real space. Four ships, one of them very large. And they were moving.Point seven five light at least, cutting straight towards Herodor. They did notslow down. They were moving at cruise speed. Attack Speed.”
- The Saint: A Gaunt's Ghosts Omnibus

帝国的舰船有时甚至能够在实体宇宙加速到95%光速。下文中做到这一点的是一艘护卫舰，所以这也可能是因为它作为小船本就更快。
原文：Warp technology permitted travel attremendous - albeit relativistic - inherently incalculable speeds, butintra-system transit remained as arduous as it must have been in thepre-expansionist epoch. At their current relative positions, Thennos was fivelight hours from Medusa. From the vibrations in the decking, Stronos could tellthat the Clan Vurgaan system frigate, the Onslaught, was still acceleratingtowards its maximum velocity, about ninety-five per cent of light speed. Oneday there, a few hours to convince the Iron Council of the logic of rescindingtheir interdiction orders, and then one day back. Stronos would be back withhis clave before the order to push out passed through the interlinkmanifold.
- Eye of Medusa

面是对于帝国战舰用于推进的反应堆的原理描述。反应堆里的物质不断而永久地被湮灭和重新生成。按照这种来回生成和湮灭的描述，舰船推进器反应堆的原理属于质能转化技术，这中间是否涉及了反物质则还是未知的。
原文：The ship’s prow projected into a largevoid, the other side of which the fusion reactor of a much larger vesselburned, locked in a perpetual cycle of matter creation and annihilation.
- Death of Integrity
这种质能转化是双向的，并且可以循环进行：物质被变成能量，能量再被变回物质，如此反复来达到长时间持续使用的效果，这种打破能量守恒的技术理论上讲可以弄出永动机，但单论这种引擎的话似乎还做不到这一点。

在大远征时期，亚空间相对平静，所以人类的亚空间航行也可以很快，远快于40k时期。那个时候他们的舰队（而不只是少数快船）数个小时就能够穿过几十万光年的距离，也意味着速度接近了10亿倍光速。
原文："Without the warp drive theImperium and its civilization could not exist. Spacecraft equipped with warpdrives can, under the guidance of a specially gifted Navigator, move into,across, and out of warp space. By doing so, a spacecraft can move hundreds ofthousands of light years in only a few hours."
- Adeptus Titanius Rulebook
下文还有另一个当时的例子。星舰能够在眨眼间横跨数个秒差距（这显然是亚空间航行），也就是10光年左右的距离（可能更大）。
原文：It was hushed like a chapel and alwaysserene, even though it controlled a starship capable of crossing parsecs in ablink.
- Ghostmaker
眨眼算作一般人的水准（0.25秒），那么这艘船就是十几亿倍光速的水准，正好和上面的那个倍数差不多。

即使是现在混乱的亚空间下，白疤的舰队也能够在几天之内从普罗斯佩罗赶到泰拉，这中间有着一两万光年的距离，也就是说跃迁的速度有一两百万倍光速。
原文：The Space Wolves legion had beenattacked and thus prevented from travelling to the Solar system. The loyaldefenders of Terra would miss the strongarm of Russ and his legion. However, their actions at least allowed the WhiteScars Legion of Jaghatai Khan to make headway for Earth. Even allowing for thevagaries of warp travel, Dorn expected the Kahn and his fleet to arrive withindays.
- Horus Heresy: Collected Visions

下面是一个上限版本的大数值产量原文，火星和地球在几天（最多不到一年）之内造出了数十万星舰。
原文：The alliance of Terra and Mars wascomplete, and the Mechanicum had outdone itself, building fleets of ships toallow the Emperor to take to the stars and complete his Great Crusade of Unity.The skies over Terra were thick with starships, hundreds of thousands of themorganised into more than seven thousand fleets, reserve groups and secondary,follow-on forces.
- A Thousand Sons
上面的造船时间不是很具体，所以按下面这段原文，这些船是花了两天（two days）被造出来的。虽然文中说是条约签订好之后的两天启程的，但是考虑到条约下来之前双方合作与否都是个问题，这意味着这些船就是这两天里出来的。
原文：The Emperor had shaken his head. 'Thevaults of Moravec must never be opened. You will swear this oath to me,Kelbor-Hal, or the union between Mars and Terra will be no more.'
Unwilling to even enter into any negotiation on the subject,the Emperor had demanded Kelbor-Hal's oath, and he had had no choice but toagree. That had been the end of the matter, and two days later the Emperor leftMars to begin his conquest of the galaxy.
- Mechanicum

这个版本原文里帝国有十亿艘船。
原文：Identica, paperwork and logs weremaintained to keep up the illusion that the Iota-Æternus was one of a billionunremarkable transports plying their trade about the Imperium.
-Sons of the Hydra

这里计算一下帝皇级战列舰接敌时派遣出的轰炸机的数量。首先，一艘帝皇级战列舰在面对对方的战列舰时派出了24个中队的轰炸机。
原文：The two Firestorms intercepted a groupof Infidel raiders flanking the main fleet to attack the Emperor classbattleship Intolerance. Three of the raiders were destroyed for the loss of onefirestorm, enabling the Intolerance to complete the despatch of twenty fourbomber wings against the Chaos Desolator class battleship Eternity of Pain.
- Battlefleet Gothic Rulebook, Pg. 113, Ships of the GothicSector
每个轰炸机中队都包含四个小队，所以帝皇级那次派遣出的轰炸机多达96个小队。
原文：Glancing out of the cockpit window, hecould see his wingmen taking up position to his port and starboard, each ofthem tens of kilometres distant but with the bright flares of their multiplemass-reactive engines starkly marking their position against the blackness ofspace. To his rear the seven other Starhawks of his squadron would also bemaneuvering into attack formation, he knew, and somewhere beyond them theStarhawks of Firedrake, Harbinger and Mantis squadrons would be doing the same,joining up with his own squadron and forming up one large attack wing as theyclosed the distance on their target. Forty Starhawks.
- Execution Hour
而后我们可以知道，每个小队里面包含十架轰炸机。
原文：Squadron Commander Milos Caparansurveyed the instrumentation panel in front of him, intoning a silent prayer ofthanks as the status runes representing each of the ten Starhawk bombers underhis command glowed a healthy green.
- Execution Hour
所以，帝皇级战列舰放出来用来对付敌方一艘战舰的轰炸机就多达960架，而且要注意的是这里的每一架轰炸机都是长度接近百米的巨无霸。

有时，帝国会为了支援一个较为重要（但依然远远达不到一二线世界或者首都标准）的星球而派出规模达到2000艘的舰队。
原文：“We detected the psychic bow waves ofover two thousand ships.”
“Two thousand?” echoed Kantor. “And you are certain theseare Imperial ships?”
(…)
"The ships are indeed human, and, in the minutes beforeyou arrived, we received confirmation that they are loyalists. The Crusader isamong them."
- Rynn's World
这里有更细节一些的描述，当时有2216艘舰船来支援，并且每一艘都不小于轻型巡洋舰（也就是说每艘长度都是四公里以上）。同时，这里面包含有八艘战列舰和数艘战列母舰作为主要的火力来源。也就是说，战列舰和战列母舰在整个舰队中的占比基本就是二百分之一，虽然这个比例比起其他很多版本的描述都更小，但是这里也把它列上来了。
原文：“Two thousand two hundred and sixteenwarp-capable ships,” said Deguerro, “and nothing smaller than a Dauntless-classlight cruiser. There are several Space Marine battle-barges, but the main bulkof the fleet’s firepower is comprised of that aboard the Imperial Navy’sEmperor- and Retribution-class battleships. There are four each of these, asignificant commitment from Segmentum Headquarters.”
