Copyright (c) 1995 by Erik Manders This submarine could probably be built today, at a much higher price and without the software and some accessories. The only thing I'm not certain about is the life support. Fuel cells similar to TL8 specs (roughly 4x better than 'current' (I assume TL7) cells) are currently being tested in Vancouver, Canada to power a bus. Aluminum hulled submersibles (TL7 expensive materials) are currently around. As for the computers, check out modern high end laptop technology. No passive sonar was installed in the belief that most relevant technology is currently highly classified and will probably stay that way. I left out ladar for similar reasons. Lasercoms might be installed, but as an (expensive) option. I don't think a periscope belongs on a civilian submersible like this one. It isn't trying to hide. This submersible is built using Vehicles 1st edition rules with april 1995 errata. The inertial compass and mechanic's toolkit are from Ultratech and are assumed to take up 14 cf all told. -- BEGIN VEHICLE -- I reserve the copyright (c) 1995 to keep other people from making money with it, but you're free to distribute this file and omit this notice in printouts for your personal use. Erik Manders 13-7-1995 (early) TL8 small cargo sub This is a fairly typical small cargo submarine, to be found plying the sealanes between the smaller undersea colonies. It is short on comforts, but boasts a reasonable top speed and large cargo capacity. Its cargo is usually carried in waterproof containers up to 400 cf in size, but this sub can carry the larger sizes, up to a single 1600 cf cargo module. This can also be a passenger pod, which links up to a collar in the cargo bay. Such a pod must bring along its own power and life support however. The passengers board and leave through the airlock. In addition to its floodable hold, this sub also has a smaller dry hold. Small goods can be carried here, and moved out via the airlock. There are also attachment points for extra fuel tanks and life support here, for when longer range or endurance is needed. The minicomps run a combination of software. Typically, every program runs at least twice for redundancy. Payload and performance is given with an empty dry cargo hold. Structure: 3000 cf standard medium body (HT 2250), maximum load 60 tons, sealed body, submersible hull with average hydrodynamics (flotation 165000 lbs, reduced to maximum load), roll stabilizers. Propulsion: one 400 KW TL8 screw propellor (DR 5, HT 225). Power: five 80 KW TL8 fuel cells (DR 5, HT 20 each), 4 standard 60 gallon TL8+ hydrox tanks (DR 5, HT 30, fire on 11) for 40 hours at full power, two 10 KWH lithium batteries (DR 5, HT 16 each). Accomodations: 1 cramped quarter. Vision: few armored portals. Crew requirements: helmsman, requiring Seamanship/TL8 skill. Mechanic(submersibles)/TL8 skill is handy. Armor: 300 points standard TL8 armor, F6/50 B6/50 L6/50 R6/50 U6/50 T6/50. Cargo: floodable cargo bay for 1600 cf cargo (bought as vehicle bay at double mass and price, pumping 1 cf water/second), 50 cf dry hold (and 5 cf waste space). Accessories: 2 bilge pumps (each removes 80 lbs/minute), high security burglar alarm, flashy paint job (additional +2 to see), automatic fire suppression system, one 4 manday TL8 limited lifesystem, TL8 cheap medium range active sonar (DR 3, HT 10, scan 15, range 2.6 miles, electronics), airlock, anchors (10 yard chain), autopilot, 2 vehicular minicams (digital), 4 midgetcomps (DR 3, HT 2, complexity 2, electronics), headlights with dimmers, 2 GPS receivers (surface only), 2 CB radios (surface only), 2 armored spotlights (DR 6/50, HT 2, exposed equipment). From Ultratech: 2 inertial compasses, TL8 mechanic's toolkit. Software: routine vehicle operation (C2, seamanship/TL8-12), database (C1, 6GB ocean maps), database (C1, 1GB ship recognition guides), database (C1, 1GB schematics), datalink (C1), computer navigation (C1), sensor operation (C2, skill 13 or +2). Statistics: cost $260670, design mass 44630 lbs, maximum payload 75370 lbs, maximum cargo load 66000 lbs (64000 in 'wet' bay, 2000 in 'dry' hold), current payload 64370 lbs, loaded mass 109000 lbs (54.5 tons), size modifier +6 (+8 to spot due to paint job), radar signature +6, IR signature +7 (+6 at 60% power or less), acoustic signature +2 (+1 at 60% power or less). Performance: speed factor 10 (14 surface), top speed 17.5 mph (24.5 mph surface), acceleration 0.9 mph/s, deceleration 10.5 mph/s, maximum sumbmerged depth 250 feet, draft 7.6 feet, MR 0.5, SR 7.
