(You’ll notice the obvious similarities to the Leviathan-class dreadnought in systems installed, which should come as no surprise; these two came off the drawing board at roughly the same time. And if you’re wondering why a BB-sized carrier has a DN-sized vector-control core – well, you’ll note that the much more tightly packed supplies of, for example, bunkerage plus AKV bunkerage, plus the need to propel all those AKVs, make it mass significantly more than a Leviathan in practice. Carriers tend to be thus.)

The core hull of the Hurricane-class drone battleship (carrier) is divided into five segments: from bow to stern, the flight operations section, the AKV bunkerage, the command section, the bunkerage, and the propulsion bus, laid out tail-lander style. The flight operations section, by design, is a hexagonal prism, flat faces to dorsal and ventral, and the other ship segments follow this pattern.

Attached to this on the starboard side, extending to dorsal and ventral of the core hull, and running from 100 m ahead of the flight operations section (to give AKVs exit and entrance cover) back to cover the first 100 m of the bunkerage, is the starship’s “buckler”. The core hull of the Hurricane-class is relatively lightly armored for an IN vessel, since carriers are intended, doctrinally, to stay out of CQB and mass conservation supervenes. However, to provide protection against long-distance fire in the outer engagement envelope, as a less maneuverable ship class, the buckler – heavy armor plate connected to the core hull by shock-absorbing trusses – covers and extends slightly beyond the two starboard facets, providing additional protection for as long as the vessel maintains the proper attitude.

The flight operations section at the bow, taking up the first half-kilometer of the ship, is effectively a single large flight deck, opened to space by an armored spacetight door in the for’ard hull. (Unlike smaller flight decks, this region cannot be pressurized.) The 43,200 carried AKVs occupy hexagonal cells clustered on the inner hull to port, starboard, dorsal, and ventral from which they launch themselves, while a small conventional flight deck at the aft end of the section provides space for the Hurricane‘s small craft. The after hull of the flight operations sections is heavily armored, to provide what protection it can against a lucky shot penetrating the flight deck.

Immediately behind the flight operations section is the AKV bunkerage section, which houses fuel and propellant, along with ammunition and other consumables, for the carried AKVs, permitting refueling and rearming. This is the most protected area of the ship, as AKV fuel and ammunition tends to be highly volatile.

The command section, the primary habitable area of the starship, is a relatively small area sandwiched between the AKV bunkerage and the carrier’s own bunkerage, also protected behind the buckler, and housing both the starship’s own operations and the majority of the outsize flight operations department. From dorsal and ventral, sensor towers extend beyond the buckler, allowing line-of-sight sensing and communications with the battlespace without exposing the core hull.

(As a side note, the Hurricane-class, like most large carriers, is an example of the IN’s dual command system. The starship itself is commanded by a Flight Commander, ranked Captain [O-7], from the line branch, while the AKV wings are commanded by a Group Captain, an equivalent rank. Overall command of both is held by a Mission Commander, ranked Commodore [O-8].)

Aft of these, a conventional bunkerage section and propulsion bus, equipped with droplet radiators for primary cooling, fills out the remaining length of the vessel.

Scattered about the length of the vessel is the same heavy-duty (“Popcorn”) point-defense grid used on the Leviathan-class dreadnought, along with 96 small turreted mass drivers – similar to those used on lighter IN classes – for heavier local-space defense.

(They are not intended as offensive weapons; the carrier has 43,200 of those in its AKVs, and would-be Flight Commanders who can’t resist the urge to take their ships into close-quarters battle are redirected towards frigates, destroyers, and other roles where such is (a) tactically useful and (b) much less likely to get one either cashiered for gross incompetence or relieved of command by an XO for whom it is not a good day to die.)

 

EEEEEEEE

shrieker: (also ping-pedo) a single-shot directional EM pulse generator mounted in a capsule suitable for mass driver deployment.

It is a truism of tactics that active sensors, while much more effective than passive sensors, can rarely be used since they are even more effective at disclosing the user’s position to other vessels. The shrieker represents a compromise with this truism; given effective localization and a little mathematics, there is no necessity for the sensor emitter and the sensor receiver to be in the same location. Thus, it provides the means to implement this by emitting the radar/lidar pulse from a point distant from the launching vessel.

The shrieker is far from a perfect solution. It provides partial information on the location of its launcher, especially if the pre-pulse run is short, or the opposition’s sensors are sufficiently sensitive to pick up Doppler distortion in the emitted pulse; and deployments are limited inasmuch as, although directional, a shrieker can only be used in situations in which its pulse will not illuminate the launching vessel or other friendlies to the passive sensors of the opposition. Nonetheless, the additional information provided by even limited active sensor capability can make all the difference in a tactical situation.

On the Role of the Dreadnought

Just to clear up a few misconceptions that may have crept in:

David Weber, alas, has done me no favors by convincing much of the SF-reading world that the standard interstellar badass is the dreadnought.

And, yes, you may remember me saying “it sure would be nice to build nothing except dreadnoughts [for ships-of-the-plane]” back when we discussed ship types, but what I did not say is that if they did, they wouldn’t be dreadnoughts. They’d be battleships, because the modal ship classes for engaging in big set-piece space battles are always designated as battleships. Says so right in the name. Battle. Ship.

Or, to put it another way, there are a lot fewer dreadnoughts than there are battleships. (And a lot more cruisers than there are battleships, for that matter, because most missions don’t have any major fleet engagements in them. But that’s another story, already told.) This is principally for economic reasons: when you examine the requirements for a ship of the plane, the battleship sits right at the bang/buck sweet spot, so that’s what you build.

A dreadnought (and to an even greater extent, a superdreadnought) has four virtues, which is why they’re built at all:

  1. It benefits in internal space from volume increasing faster than surface area, which makes it a convenient class to carry extra stuff, from complete flagship suites through shipyard-class repair facilities for its cohorts and prisoner-of-war blocks to all that is required for the many, many specialized variants on the books.
  2. It can afford a hell of a lot of extra armoring, so you are significantly less likely to get your admiral shot off and your fleet coordination suffering if you give him a DN to ride around in.
  3. It can mount a Really Big Gun of the kind you’ll rarely need to use, but you might miss if you didn’t have any of in your plane of battle.
  4. It’s bloody terrifying. When naval architects are told to draw up plans for a DN or SD, the unspoken requirement is that it dominate the battlespace like Conan the Barbarian at a convention of preadolescent pacifists: it dreads nothing, and everything dreads it.

So there aren’t all that many in service, relatively speaking. There don’t have to be – say, speaking non-canonically and off the back of the envelope, eight squadrons in the Capital Fleet (mostly in the Sixth Flotilla, which is the IN’s heavy-hitting force), four squadrons in Home Fleet, two for Field Fleet Spinward (which borders on the Seam), and one for each of the other field fleets: say, 228 in total, not counting specialist classes and the reserve.

You can assume at least four times that in BBs.

 

NO STEP

(Obvious idea is obvious.)

walkplate (n.): A walkway for magnetic boots (q.v.). Since starship hulls in the modern era are manufactured from a variety of light composites very few of which are significantly ferromagnetic, such walkplates are necessary to enable crewers on EVA to remain attached to the ship.

While early examples of walkplates were simply bolted to the hull, recent designs – preferring to maintain clean lines for the sake of elegance – embed a thin mesh of iron-alloy within the outermost layers of the hull structure, sufficient to be gripped by heel and toe electromagnets. Embedded v-tag transmitters and/or hull markings provide guidance as to which parts of the hull can safely be walked upon.

Transplague Ship

PROCEDURES IN THE EVENT OF IRREVERSIBLE CONTAMINATION

In the event of irreversible contamination by biological or nanotechnological plagues, and standard quarantine responses are deemed insufficient, either (a) as declared by consensus of the Flight Commander, Environmental Systems Engineer, and Flight Surgeon, or (b) as imposed by order of a duly authorized representative of the Emergency Management Authority, the following actions are to be undertaken:

  1. The Flight Commander is authorized to maintain order aboard by any means necessary, including the use of lethal force in such circumstances where it would not otherwise be permissible.
  2. All airlocks and spacetight doors providing sophont access to the exterior of the vessel are to be placed in the closed and sealed state; their local control systems rendered inert by null-flashing; and secured in the sealed state by welding or other permanent closure.
  3. All other apertures, of whatever purpose, providing access to the exterior of the vessel are to be placed in the closed and sealed state; their local control systems rendered inert by null-flashing; and secured in the sealed state by welding or other permanent closure. This is to include all apertures used for the jettisoning of waste, and all radiator systems in which coolant is exposed directly to space, without exception.
  4. The Flight Commander shall designate the most appropriate compartment within the vessel for the temporary storage of such waste material as can no longer be jettisoned and for known-contaminated material that cannot be properly disposed of, including corpses.
  5. Once a stable orbit which does not take the vessel into the local forbidden zone of planets, moons, habitats, or other bodies (see Quarantine) has been established, the flight control systems of the vessel, including local drive controllers, are to be shut down and rendered inert by null-flashing.
  6. All running lights of the vessel are to be configured to display the “death ship” pattern, as prescribed by the Imperial Navigation Act: a 2p period of yellow-quarantine alternating with a 1p period of crimson-caution.
  7. An EM beacon is to be configured on the local-distress channel, broadcasting the following repeating message: ALERT CASE ICHOR I SAY AGAIN ALERT CASE ICHOR. VESSEL [registered name] IS UNDER SEQUESTRATION. DO NOT APPROACH UNDER ANY CIRCUMSTANCES. IGNORE ALL CONTRADICTORY TRANSMISSIONS. MESSAGE REPEATS.
  8. If the vessel possesses a point-defense system, this system is to be configured to fire upon any other vessel attempting to dock with or otherwise close to within the forbidden quarantine zone (see Quarantine) of the irreversibly contaminated vessel, other than a vessel whose transponder is signed with the Emergency Management Authority private key.
  9. At the Flight Commander’s discretion, euthanatoics may be issued to passengers and crew.

UNDER NO CIRCUMSTANCES IS A VESSEL MARKED BY THE PREVIOUSLY SPECIFIED SIGNALS TO BE APPROACHED BY ANY OTHER VESSEL OTHER THAN IN RESPECT OF SPECIFIC ORDERS ISSUED BY THE EMERGENCY MANAGEMENT AUTHORITY.

Any vessel which

  • docks with; or
  • takes aboard passengers, cargo, flotsam, jetsam, or debris from; or
  • enters any emissions plume, from any source whatsoever, of;

an irreversibly contaminated vessel shall itself be deemed irreversible contaminated, and all the foregoing procedures and warnings shall apply to it in like wise.

IN THE ABSENCE OF SPECIFIC ORDERS ISSUED BY THE EMERGENCY MANAGEMENT AUTHORITY, ANY IRREVERSIBLY CONTAMINATED VESSEL SHALL BECOME SUBJECT TO ARBITRARY DESTRUCTION BY LOCAL AUTHORITIES NO FEWER THAN 72 HOURS POST-DETECTION, PROVIDED THAT SAID LOCAL AUTHORITIES COMMAND MEANS TO DO SO IN ACCORDANCE WITH THE CAUTERY PROTOCOL, LATEST ISSUED REVISION, ENSURING THE SAFE DISPOSAL AND NON-DISPERSAL OF CONTAMINANTS.

 

Some Leviathan Numbers

Just to clarify the capabilities of those mass drivers, and note, this is back-envelope work.

So, we’re going to stick a big dumb projectile in the breech. By big, dumb projectile we mean a 2400 mm k-slug of soft iron (iron being cheap as dirt, and really, what it’s made of doesn’t matter all that much in this application), and we’ll call it a 2400 mm diameter cylinder, 4800 mm long. That’s 22 m3 of iron, massing 173 metric tons.

If we crank a Leviathan primary up to full power, we’re going to be sticking about 10.1 exawatts (usable) in the flash accumulators; that’ll accelerate that projectile at around 1.1 million gravities for close to a second, meaning it leaves the muzzle with a velocity of 0.036 c, i.e., in the low-relativistic regime. Impact energy delivered to the target is on the order of 2.4 gigatons.

This, needless to say, is way too much boom for almost all practical applications, and no-one routinely stocks that kind of k-slug or runs their mass drivers at that power level, not least because it’s gonna take enough time for the shipboard powerplant to put ten exawatt-seconds in the flash accumulators that you sure aren’t going to be able to fire one of those shots every second, or anything close enough to it to avoid being a big, fat, wallowing target. There are uses for Mighty Glaciers and uses for Glass Cannons, but there’s no use at all for something that’s both.

But if you happened to be interested in what the hardware could deliver if you wanted to comically overkill something with no means whatsoever of fighting back, there are your numbers.
