Patrick Tucker at Defense One describes the Starpoint design for a future warship called Dreadnought 2050. It is the product of an open-thought experiment at the informal request of the U.K. Ministry of Defense.
The ship would be powered by hydrogen fusion — or if that proves unworkable, then at least by “highly efficient turbines driving silent electric motors to waterjets.” The hull is composed of “ultra-strong” composites of the finest acrylic.
Dreadnaught 2050 would have
* microwave guns
* combat lasers
* supercavitating torpedoes
