Mapping the Lunar class cruiser

By Voronesh, in Rogue Trader House Rules

["In this post I will discuss number games, based on the Sword class frigate"]

Greetings fellow Explorators and Rogue Traders. In this transcript taken from STC printouts found far in the Koronus Expanse; humanity of ages past has disclosed much information about the formidable staple of His Holy Navy.

The Lunar class cruiser is not so much a single class of ship tself, but rather; true to STC workings; a baseline upon many different types of vessels have been based, by continual permutations and dictated by the Imperial war effort.

Regardless if a certain Lunar has been constructed with a solid spine or a keel as a base, the vessel will invariable measure close to 5 kilometres in length from stem to stern. Walking from port to starboard one will walk an 800 metres to reach the other side. Taking lift from the Navigators spire atop the ship, one travels a holy 1100 metres down to the spine to reach the keel landing bays.

The volume of Imperial might away from an Imperial planet measures 4.4 cubic kilometres. A veritable hive of holy machinery. The space available to multipurpose decking; based on STC fragments from Mars of 30 metres of height; is a grand 146 square kilometres.

The holy ritual of fittings dictate 75 space allocations to be available to a Lunar. The Archmagos responsible has thus 1.95 square kilometres to consider fittings for; 75times on Lunar.

On many Lunars this will dictate around 35-40 major decks, each of which may well be structured into many smaller subdecks.

[To the matter of having enough operators and subservient ratings, the STC printout only mentions this]

To fully crew such a mighty vessel with enough ratings to work the macrocannon broadsides or lance batteries; or the Omnissiah willing, a holy Nova cannon, it needs around half a million souls. [This number can vary greatly as you probably know best yourself; depending on the actual craftmanship of your macrocannons or if lances which require alot less ratings are aboard a ship. Some Forgeworlds can still fit autoloaders to a ships macrobatteries, greatly reducing the need for ratings in those areas, but most Forgeworlds do not fit such holy devices, if cheaper human resources can be used instead.]

Now fellow Explorators, this does pose a great many possiblities for fitting a ship. While true fitting is the realm of Archmagi at Forgeworlds, many of us serving the Omnissiah aboard a Rogue Trader vessel have to replicate the lesser rituals of refitting ships to better suit the varied needs of different Rogue Traders.

Most interesting are components like cargo holds and others of this ilk.

The basic cargohold has roughly 4 square kilometers of 25 metres height (if one allows some extra metres for maintenance work) available. This is roughly the footprint of the Lunar class cruiser, which no sance Rogue trader would do. Far more probable is the stacking of multiple decks reserved for cargo. This shows again how much loot and valuable archeotech can be brought back by Rogue Traders even with a single Lunar cruiser.

If one were to erect a temple for the God-Emperor in his flesh form, the monastery on the ship could support hundreds if not thousands of missionaries, and many, many more supplicants and penitents to be served on such a vessel.

The bridge itself is far from a trivial matter either. its huge size is mandated by additional control rooms along every major installation, with secondary backup bridges situatied near the plasma drive; the warp drive; the geller field, even the Sensorium has a smaller eplicate bridge available. it is far from the small room that the Lord Captain and Rogue Trader resides in most of the time.

Thanks for this information has to be given to others Explorators i have met during my travels here on these cogitator circuits. Unfortunately their designations have slipped my limited cogitator and databank assets.

Impressive work, most impressive. The Omnissiah be praised in the glories spreads before us.

Do these works include dimensions of the torpedo rooms and flight decks? Of course a true Lunar class vessel will not have flight decks but the Dictator class does and is based on Lunar hulls.

Regardless I look forward to reading more of these treatises should they become available.

We have high hopes that further research into an undisclosed location, can provide further STC printouts or at least passing notes on various technlogy. Current archeotechnological digs are turning up relics in relation to naval technolgy.

We sincerely hope to be able to at least briefly touch on most ship components His Holy Navy currently employs.

Greetings my fellow Explorators.

This time we shall digest and evaluate the printouts concerning the sole purview of the Adeptus Mechanicus aboard any ship. The huge plasma drive and the nearly equally large warp engine. It is well know that aboard most vessels our domain encompasses nearly a third of the ship, and this is true on the Lunar as well:

The plasma drive located in its only logical location fills the ship from top to bottom, from port to starboard. It also goes a whole kilometre towards the bow. All this area might be beneath the bridge, but it truly is the heart of the ship. Amongst these hot and plasma rich environment thousands of servitors and electro priests will perform many tech rituals to keep the plasma drive functioing smoothly and to appease its machine spirits, lest dangerous overloads might happen. The given thrust of the plasma drives allows it to reach speeds in excess of 100'000 kilometres per hour, even while supplying power for all of the ships weaponry.

The Warp drive is nearly equally large, filling another good 750 metres of the ship. While the Empyrean is a dangerous terrain, it is a necessary evil for humanity as a whole, and this sacred machine lets us rip a hole into the matter of the galaxy and pushes the ship into the warp. Activation of the warp engine is a precarious thing, and should only happen when outside a systems severe gravity and particle streams emitted by the sun. The training requirement for the correct tech rituals is quite high in this part of the ship, chief amongst the reasons is the fact that one is dealing witzh powers that one cannot see or measure as reoutinely as a power flow.

A full 1750 metres are given over to our holy order, not be by trifled with by the other power aboard a ship. We are the metal base upon which the command of a ship rests. Literally as well.

The bridge is often situated atop the spine of the ship at the every end, overlooking the dorsal weaponry. This tower of command alone rquires a huge area to truly function well. While secondary bridges are factored into the plasma drive and warp engine there is still alot of space dvoted to the smooth functioning of the fleshbags aboard the vessel. A full 8 main decks is this tower high, measuring easily more than 500 metres in length and nearly 400 metres wide, additional command structres are formed along the dorsal spine of the ship to monitor the sensoria. Housed within this structre are the main command bridge a veritable hold of ancient technolgy; a giant holotank measuring 4 metres in height and 2 metres in diameter allows projection of mutiple warzones both of void and planets. The room is filled with rows of servitor and human crew operating hundreds of viewscreen and vox machinery. Hundreds of reports reach the bridge every few minutes and must be evaluated.

Another place of importance is the Navigators spire, situated either atop the bridge or right in frot of it as an independent structure. In close location are normally situated the Astropath chambers. Both of which are other powerful factions aboard a ship, and have equally grand; why grandeur if one lives in embrace of holy machine?; quarters.

Fricken cool. Please continue.
