Project Hammerhead

Project Hammerhead (code name Mjolnir) is a top-secret Galactic Armada threat response and espionage platform on Calpha. It is normally stationed between 1,000 and 2,000 km below Calpha's surface, well below where any rational being would be, and is shaped like a giant fish with a hammerhead-like face. This disguise is completed with magnetic and electromagnetic shielding as its "skin" that will make it inconspicuous to any cursory scan and to many thorough scans. The base is over 400 long, powered by a nuclear reactor, stocked with enough food to last its crew weeks and a desalination system to provide water. It is equipped with an array of sensor and communication equipment, armed with torpedoes, ballistic missiles, and numerous guns, and docks several fish-shaped pods for outside repairs, carefully-timed trips to the surface for re-provisioning, and dogfights when necessary. Project Hammerhead is intended as a covert strike platform that can rise from its hiding depth to attack surface, air, or even orbital targets completely unexpected and largely undetected. Should situations become so dire, the base can even launch above the surface and act as a flying battle platform.
