In addition to the 3 9fib computers aboard the Aeolus-class, there is a TL-16 10fib prototype, which handles most of the shipboard automation. The computer's official designation is PATER (Prototype Automation Task Evaluation and Resolution). It is largely synaptic, has a synthetic personality, and is integrated into the shipboard computer network.

The Elissa has a total of nine decks (numbered 0 thru 8). Deck 0 is really nothing more than a branching corridor leading to the ship's 6 dorsal rider mountpoints. All spaces beginning 96 meters aft of the bow, and extending all the way to the stern, are engineering spaces (jump and maneuver drives, life support, and ship's powerplant). A triple hangar facing the stern on decks 1 and 2 contains the ship's shuttle. A second hangar directly below that (on decks 3 and 4) provide housing for for a pair of high performance fighters (currently, only one is aboard).

All space between 48 meters aft and 96 meters aft consists of three huge cargo bays. Cargo bays #1 and #2 span the top four deck spaces (decks 1 thru 4) (each cargo bay is two decks high). They each measure 48 meters long, 42 meters wide, and 6 meters tall. Cargo bay #3 consumes the lower four decks (5 thru 8) and has the same 'footprint' as the upper two cargo bays, but is 12 meters tall.

All space forward of 48 meters contains the bridge, crew quarters, communications and computer spaces, the crews mess and lounge, sickbay and the low berths, and the new physical sciences compartment (formerly the compartment housing fleet CiC). (The computer 'pit' refitted for PATER was formerly the officer's mess.)

The primary access from the bow compartments to engineering is via a sealed "service alley" which runs across the deck of the #2 cargo bay (levels with deck 4). This tube is bonded super- dense (just like the outer hull) to provide added security so that a cargo bay breach will not isolate engineering for the forward compartments. The forward and aft ends of the service alley also contain the primary grav-lifts connecting the other decks of the ship (although there are other access points). The aft service alley grav-lift is also the access point from inside the hull to the dorsal rider mounts. This is specifically designed as a 'choke-point' to increase the difficulty of hostile boarding parties using the ridermounts for forced access to the ship.

The aft half of cargo bay #3 has been separated from the forward half of the bay by a new (temporary) bulkhead. The aft section has also received installation of additional inertial compensators. The lower half of the compartment has been gunnited, flooded with seawater, and stocked with Ukenuu from Ridan [0612/Reaver's Deep] (an icthyoid very similar in size and biological make-up to the Terran mackerel). This makeshift "swimming pool" for Doejin has water filters and chemical compensators built into its' walls to maintain the fresh state of the water.
