Since you all wanted to know what I was on about, here's a "second draft" of what I've been working on. There are definitely parts that could be improved. This A2L design accomplishes: Atmospheric Capability, for Close Air Support 8 dT of Bridge 1 dT of Ship's Computer (Should be Hardened and optimized for Navigation) Engineering Bay consisting of: 13.5 physical dT of Power Plant + 5.5 dT of maintenance margin for 19 dT of type F Power Plant, 14 physical dT of Jump Drive + 6 dT of maintenance margin for 20 dT of type C Jump 2 Drive, 6 physical dT of Maneuver Drive + 4 dT of maintenance margin + 1 dT of Maneuver Drive behind the forward turrets for 11 dT of type F 4G Maneuver Drive, exactly 4 dT of sensors + 1 dT of sensors ahead of the forward turrets for 5 dT of Very Advanced Sensors, and exactly 2 dT of Fuel Refining 60 dT of Jump Fuel 18 dT of General Purpose Fuel 10.5 dT of mixed use Day Cabin, Ready Room, & Kitchenette 11 3 dT Staterooms: Chief Executive - Colonel Lloyd Robertson Captain & Pilot - Gev Navigator Comms & Sensors Operator - Charoux Bridge Gunner Port Gunner Stern Gunner Chief Engineer - Gerald Ship's Doctor - Dr. Lyireh Ros-Galyin Barek Troop Discipline, Brig Warden - Sergei Andronokov Unassigned (Bodyguard?) 7 dT Executive & Passenger Lounge & Galley (unfinished) 1 dT of Life Support System 4 dT of Air Raft Bay All turrets remote, rather than manned in place (2 Gunning Stations unfinished) 2 lasers and one missile launcher on both forward guns, 2 sandcasters and one laser on the rear gun; multiple target tracking at both long and short range, fully spherical laser defense coverage, and sandcaster defense focused to behind 13.5 dT of Docking Bay for 10 dT of Ship's Boat, for impressing clients (who need to choose to hire us, and should be impressed by our "Armored Limousine" style travel accommodations) 2 dT of Client Impressing Office (unfinished) 4 dT of Secure & Armored Stateroom for important guests 4.5 dT of Machine Shop & Electronics Lab, including 1 dT of machining centers, 1 dT of Utility Computer, 0.5 dT of component & raw material space, and 0.5 dT of circuit board manufacturing & analysis space 6 dT of Briefing Room & Lounge with an additional 2 dT of Galley 7.5 dT of Barracks with apparent room for 10 Mercs 4 dT of Armory & Equipment Lockers (plenty of space for weight lifting?) 6 dT of Vehicle Bay for ground vehicles + 4 dT of Ground Ramp 2 1.5 dT large airlocks with emergency gear stowage 6 dT of Med Bay with apparent room for 7 patients 3 dT of Brig This A2L design fails to accomplish: Jump 3 Fuel for 2 Jumps Screens Major anti-ship weapons Cargo Strict conformance to Classic Traveller rules (someone do the math, please!) Completeness Ultimately, I think we needed 400-500 dTons. ^_^;
