Just thought I would post the desc and specs on the engines the Dido is equipped with. This is one of the engines available in BTS!
The Tech research project:
Internal Fission Drive: Solid Core
Tech Level Requirement Engineering 8.5, Physics/Mathematics 8.3
R&D Requirement Nuclear Power, 15 Star Yard Slipways, Microchips
Successes Required 6
The various Internal Fission Drive designs and the external pulse drives are the real workhorses of the TL 8 and 9 powers, assuming a good supply of their rare fuel can be obtained. Fissile isotopes are very rare in Population 2 stars, but fairly common in Population 1. In very young or very active star-forming regions, many usable isotopes may be common, but in most star systems, only three isotopes are available, U235, U238, and Th232. Hydrogen or ammonia is the most commonly used reaction mass with these drives. The performance envelope for these drives is very broad, and almost completely determined by the sophistication of the internal shielding available. The lowest performance drives use centrifugally contained solid cores, and need relatively little internal shielding as they are quite cool. The Solid Internal fission drive has an impulse rating of 800 seconds. A thrust to weight ratio of 10 to 1, and a total delta-v of 12.4 m/sec. Completion of this project allows the Power to design and build space vehicles using the Reaction Drive (Internal Fission: Solid Core) as a means of propulsion.
The Drive description in the Naval Construction Doc:
System Drive Reaction: Internal Fission Solid Core (Eng 850/Phys 830) Speed: 12.4 m/sec
+3% addition to speed in space for multiple drive levels
Increases initiative bonus when using flank speed
Requires fuel upkeep
