Four thousand L-Hyd tons displacement and designed for travel into the hinterlands. It had back up maneuver and jump drives just in case. A level of detail typical of British Traveller material.Anyway, back on topic, before you can design warships / fleets you need to know the technology available.  In Traveller I had three broad categories of ships based on weaponry. In Traveller, the three size / power categories of weapons were "turrets" (small, typically taking up 1-2 tons), "bays" (50-100 tons) and spinal mounts (taking up thousands of tons). Weaponry dominated my ship types. Escorts were small ships (this includes destroyers, frigates, etc.) massing 1,000 tons or under. A ship could have 1 turret per 100 tons displacement. Cruisers (light cruisers, heavy cruisers, frontier cruisers etc.) massed 3-20 thousand tons and had bay and turret weapons. You could have one bay per thousand tons displacement. Capital ships (battleships, battlecruisers, etc.) were (literally) built around spinal mounts with bay and turret weapons supporting the main armament. A ship could only have one spinal mount. Capital ships tended to mass 50,000 tons plus. You could build ships up to 1,000,000 tons but still have only one spinal mount per ship.The point is, my ship types were determined by the weapons available and the size of ship needed to carry them. Maneuver drives were not too different in capability and jump drives were similar in ability across ship types. The jump drives were capped largely by the tech level of the yard building the ships.Different technology would have altered the ship types and sizes.</blockquote>
