51peg Corporation 2500v « Whitefin « 

The 2500v model is the state-of-the-art atmospheric surf vehicle. This gorgeous ship is used by daring competitors during surf races around Jupiter, Saturn or others giant gaseous planets. Here, the Whitefin can show her potential with a twin mode burst-ion jet : this engine delivers outstanding performances in near space or atmospheric environnements.

51Peg Corporation « Narwhal » mk 1 et 2

Initially, The Narwhal mk1 (above) was designed by 51Peg Corp as a high-end civilian interplanetary ship. But her speed and low radar signature has been noticed by the military. The weaponized version is consequently used as solar systems patroller or long-range scout. The mk2 (below) larger is equipped with a more powerful ion engine (thrust-to-weight ratio reachs 10 !)and various missiles may be fitted in the mid section bay.

Submersible Drone Carrier

Design from https://www.popularmechanics.com/military/navy-ships/a29576235/drone-launching-submarines-aircraft-carriers-win-next-battle-of-midway/ (Kyle Mizokami, Hi Sutton).

This is a concept for a submersible drone carrier, designed as an answer to aircraft carrier vulnerability to modern anti-ship missiles. This carrier can accommodate unmanned combat aircraft vehicles (UCAV). Without manned aircrafts this ship should be smaller and cheaper, needing less crew. The submarine itself will not reach great depths, keeping the ship watertight is difficult with huge deck elevators. Neither masts nor periscopes are visible…. this could be a problem, I envision a smaller companion ship fitted with all this and anti-aircraft systems.
