“Finally, let us turn to the biggest megaships of them all, the fleet carriers. Including them in this work is a choice which I expect to be somewhat controversial – many would argue that a fleet carrier is a formation, not a vessel – but with respect to those readers who may hold that position, since the Imperial Navy treats fleet carriers as a single vessel for asset accounting and command designation purposes, so in turn shall I.

“Let us begin with a look at the history of the type. Fleet carriers were not known before the Exterminomachy (5782-5901). While before that time lighthuggers had met with occasional hostility, they had proven more than capable of defending themselves against local system defense forces, in particular with the Perreinar Wheel1 – and in those cases where they were not, it was because they had encountered a Power not readily opposed by pure military force. This changed with the arrival of the skrandar berserker probes, whose numbers and willingness to embrace suicide tactics made them a serious threat to even well-defended vessels, and eliminating breeding site for which required the transport of full task forces to their host systems.

“The first fleet carriers, then, were improvisations; lighthuggers pressed into service under the right of angary. Stripped down by removing all cargo capacity, much crew space, and all other less-than-essential facilities, and enhancing their fuel capacity with multiple drop tanks, it became possible to clamp a small number of light units – overstocked with fuel and supplies – to the spine of such a vessel, and have it haul them slowly and painfully to a target system.

“Such crude improvisations were fraught with problems, from wear and tear on ships and crew during the slow transit, to the risk of interception before the transported units could free themselves from the carrier – both due to the inefficiency of the mechanical clamps, and the need to cut clamps frozen in transit or actual hard welds used where clamps would not suffice, to even entire vessels lost from the carrier in transit. (The last of these to be recovered, CS Bloodwashed3, was salvaged with all hands in 6722.)

“Fortunately, by the third year of the Exterminomachy, new designs were emerging from the cageworks at Ashen Planitia and Armory. The second-generation fleet carriers were custom-built starships, or rather, the specialized elements (the “propulsion head” and “collier module”) were, since the second generation eschewed the rigid designs of the first in exchange for dispersed tensegrity structures.

“In effect, the starships transported by the fleet carrier, along with the specialized elements, formed the floating compression struts of the overall structure, while being linked by braided cables (derived from orbital elevator technology) into a unified structure. The majority of the propulsive thrust is provided by the dedicated propulsion heads, while specialized fleet mediator software enables the use of the drives of the various carried ships to balance the structure and correct attitude. Meanwhile, supplies carried in the collier modules, distributed by rigged flexpipe and by cable-crawling logistics robots, eliminated the need to overload any individual ship with supplies, and indeed enabled the transportation of greater volumes of fuel and replenishment. Moreover, such fleet carriers could separate instantly if intercepted by simply blowing the explosive cable-couplers and engaging their drives independently, the dispersed tensegrity structure providing adequate safety separation for this.

“Such dispersed-design fleet carriers served with distinction throughout the remainder of the Exterminomachy, and have remained a key element of IN subluminal doctrine since. While there exist a third generation of fleet carrier designs, these merely reflect the evolution in technological reliability that allows the physical cables of the second generation to be replaced with vector-control tractor-pressor beams, and does not reflect any change in fundamental design or doctrine.

“As ad hoc structures, of course, it would be incorrect to say that fleet carriers have classes, in the strictest sense. However, the individual propulsion heads and collier modules, the former full starships in themselves, do. Thus, we shall begin our examination of fleet carriers with a look at the most common propulsion head in Imperial service, the Legends-class…”

On AKVs and Survivability

From the questions box:

Dear Gentlesoph,
Having been reading your posts, I have a question about AKVs such as the ‘Daggerfan’ and ‘Slasher’ classes. With high-powered lasers capable of doing damage at one light second, how do AKVs survive the 300,000km journey into single kilometer range? As stated in your ‘Nonstandard Starship Scuffles’ post, military vessels use armor woven through with thermal superconductors dumping heat into ‘thermal goo’. I assume this armor/thermal management system applies to AKVs as well, although you also state that point-defense lasers will shred a vessel unfortunate enough to get into very close range. How can an AKV survive at single kilometer ranges long enough to inflict damage on the target? Thank you for your time, I look forward to more posts!

Well, there are two parts to this: how do AKVs close to skin-dancing range, and how do they survive when they get there? I’ll take ’em one at a time.

On the first point: with great difficulty.

If you take a wing of AKVs and throw them at a fresh battleship, all you’re doing is providing its point-defense computers with skeet; they’ll be chaff and charnel before they get anywhere near the inside of the BB’s point-defense zone.

What you have to do is wear it down first. That’s is the job of the non-carriers on your side of the fight: throw a lot of kinetics at the enemy to make their PD work hard. That does three jobs: one, it keeps the PD grid busy in itself; two, any of it that gets through may just take out a chunk of the PD grid; but most importantly, three, by making them run their point-defenses, you’re building up heat in their ship. Your non-carriers also have the job of pumping heat into their ship directly with the big lasers.

That heat, in turn, is going to eat away at their PD efficiency in a variety of ways. Most simply, it’s going to have to cut back on its firing rate once the heat sinks start filling, because otherwise the crew will cook, but also the hardware becomes less efficient, processor error rates go up, and similar badness ensues.

That’s when you send in the AKVs, and you send in a lot of AKVs mingled with a lot of chaff and decoys, swamping the capabilities of the now-degraded PD grid. They won’t all get through – you plan for a lot of them not to – but once the grid’s sufficiently degraded, enough will to ruin the BB’s day.

As for when they’re there? Remember, they’re described as operating within the point-defense envelope, which is to say, inside its inner boundary, which is defined by the minimum effective range of the PD – set by a variety of factors, such as the range at which firing the PD will seriously damage your own ship, but of which probably the most important is the ability of the PD to track the target and slew to fire on it. At the sort of hug-the-hull sub-km range AKVs like to operate at, it doesn’t take much velocity to generate a huge traversal angle, and what you can’t track, you can’t reliably hit.

(And it’s hard for your screen to fire effectively at the AKVs ruining your day, ’cause even discounting the effects of the AKV exploding at point-blank range, every miss will hit you.)

All of which is to say: While there are some subtleties and complexities to the tactics (defense AKVs, screening vessels sharing PD, etc., etc.), the short answer is it takes a lot of work and losses to get an AKV force within range of a target, but once you do, that target is dead meat.

(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.)

 

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.

From without, the Leviathan-class dreadnought resembles a slender wedge, a dagger-blade without a hilt. It is, of course, rather larger than virtually all equivalent dreadnought classes and even some superdreadnought classes seen elsewhere, in keeping with the Empire’s naval construction policy of “shock and awesome”.

This should come as no surprise to anyone, since the realities of armoring such a vessel mandate such a glacis, and as such virtually all ships of the plane, of whatever origin, share this common feature. The Leviathan mixes this up slightly, having a change in ratio along its length that gives the hull a subtle curve and the ship entire a forward-leaning, sleek and hungry look.

(Although those who serve aboard Leviathans, especially back in the maneuvering sector, tend to describe their workplace as the ship’s “fat ass”.)

As is also usual, the apparent outer hull of the vessel is entirely composed of armor plating, which in the case of the Leviathan is a little over 30m thick, comprised of multiple layers of heavy plate, Whipple foam, radiation-absorbent material, thermal superconductors, dilatant shock gel, flexible spreader trusses, and other necessities for survivability in the modern high-energy battlespace, many of which remain classified.

(The important thing to remember about this armor plating is that it is not there to protect against a direct hit from an opposing capital ship. No practicable material will do that. It’s there to protect against the spallation debris left behind after your point-defense grid sweeps the sky like the hand of an angry laser-spewing god.)

This armor serves as a backup to the triple-layered cyclic kinetic barrier system with which the Leviathan is equipped, along with the likewise triple-layered ray shielding to protect against photonic attack.

The majority of the space within this outer hull is unpressurized volume, occupied by machinery space, bunkerage, stores (tanks and unpressurized cargo holds), accessways, robot hotels, and magazines. The habitable volume is represented by a relatively small (roughly equivalent to a 232-storey building, laid out tail-lander style) cylinder buried deep within this, above the axial passage for the primary mass driver, with two attendant counter-rotating gravity rings providing space for gravity-requiring special facilities. Below and to port and starboard of this passage can be found the eight fusion reactors providing non-thrust power to the Leviathan.

In addition to the primary (axial) heavy mass driver, the Leviathan mounts four secondary heavy mass drivers of only slightly lower power along its dorsal-ventral centerline, spread out at 15 and 30 degrees off-axis (although with off-bore firing capability), along with four heavy grasers clustered around, and aligned to, the axial primary.

Tertiary weapons systems consist of 64 turreted mass drivers and 32 turreted heavy lasers, of which half can slew far enough to be capable of broadside firing. An additional eight turreted mass drivers are mounted on the stern for kilt defense, should the prospect of attacking through, or at best in close proximity to, the emissions plume of the Leviathan‘s 24 torch drives not be sufficient deterrent. Finally, the Leviathan is equipped with the Artifice Armaments “Popcorn” laser grid for point-defense and CQB purposes, ensuring that anyone foolish enough to close to point-defense range will have mere microseconds to contemplate their folly before vaporizing in one of the most spectacular coruscations known to sophontkind.

Also pressurized are portions of the “docks and locks” sections to port and starboard, 500 meters for’ard of the drives, which house the Leviathan‘s small craft complement. These are buried beneath the starship’s outer hull armor, which is designed to retract under non-combat conditions to provide ingress. In light of this, the multiple AKV wings and drones are launched via dog-leg tubes through the dorsal and ventral armor, and recovered – if this is necessary during an engagement – when circumstances permit turning broadside to the enemy and recovering through the far-side landing bay.

As a dreadnought, the Leviathan is equipped with a flag bridge and communications/tactical mesh suite for task force command; with the capability to effect repairs on smaller vessels of its task force; with the ability to deploy starfighters for patrol or remote operations missions; and with a substantial espatier force and the means to deploy them, whether in boarding operations or for groundside raids.

The Hornéd Moon-class is a small starfighter intended for fast attack and fast insertion missions in planetary orbit and deploying to the surface. As such, it has atmospheric capability, and even the ability to land.

In overall form, it resembles – as the quotation indicates – a croissant or crescent moon of flying-wing conformation, with the thin “inside” edge of the crescent facing forward. The two forward-facing points of the crescent are rounded, and rise to a near-cylinder at the for’ard end, and a rectangular section of the central section is “humped” at the rear; this contains the drives, whose nozzles protrude from this rectangular shroud aft.

Atop the starfighter, paired hardpoints on the dorsal hull to port and starboard hold the AKVs, when mounted. Additional mountings near them permit jettisonable fairings to be used to permit atmospheric entry or departure when non-streamlined AKVs are carried.

In between them, atop and for’ard of the drive shroud, radiative striping mounted directly atop the hull, beneath protective shutters, provides heat dissipation. To provide additional control (to the reaction wheel system) when in atmosphere, a number of multiple-purpose aerodynamic control surfaces are mounted along the leading edge of the hull, and to two small vertical stabilizers at the port and starboard edges of the drive shroud. Deployable rollagon landing gear are fitted ventrally in a multiple tailwheel configuration.

The main body of the ship is entirely devoted to fuel storage, with multiple deuterium tanks wrapping around the small antimatter cryocels for maximum protection. Meanwhile, the starboard near-cylinder provides housing for the ship’s avionics, including (beneath the forward-mounted radome and associated shuttered ports) for the triple sensor suites and tactical communications systems.

The starship’s small habitable area is located in that to port; the forward-facing airlock (whose outermost section is covered by a retractable streamlining fairing and extendable airstair) at far port gives onto a short corridor providing access to, in order, the ship’s bridge (behind an open viewport for close-maneuvering use), a two-pod sleeping area, a small room tripling as galley, fab shop, and rest area, and a single-person ‘fresher at corridor end. Limited avionics and life support access is possible through panels in this area; however, there is no pressurized access to the main avionics bay in the starboard near-cylinder or to engineering systems; such access requires EVA. Likewise, if drop pods are carried, access to those (for pre-deployment boarding, say) is only possible through EVA.
