Note: For the examples of spacecraft design posted on this blog, I mostly use 2ed. Mongoose Traveller rules, but some examples using 1ed. rules will persist until they can be upgraded.

Look at the side column for variant rules I use in my campaign.

300dt TL9 Antique Systems Defense Boat, Mk2


Built using older techniques that would put crews in space for lengthy periods of time, this class of gunship is still used in frontier systems, out-of-the-way planetary pickets and by relatively low-tech planetary navies. Launched into space around an important area that requires protection, the defense boat’s job is to lay in wait for word from patrols that a threat is in-bound. By the time the threat has arrived, the defense boat will be in position and can begin launching its deadly torpedo payload. Normal crew is the captain, a pilot, 2 engineers and 3 gunners. TL9.
This vessel, designated Mk.2, has been produced for export in compliance with Imperial regulations against so-called "dirty" power plants. The main fission reactor has been removed and replaced with a fusion reactor, and the armament changed. For the picture above, you have to imagine these changes.
