U1

The U1 is a nuclear submarine and stationary vehicle in Just Cause 2.

Appearance
It's about 510 m long and much bigger than any real submarine. The biggest real one is Project 941 (a.k.a. Akula, a.k.a. Typhoon), being "only" 175 m long and 23 m wide.

The U1 has a lot of corners. So many in fact, that stealth was obviously not a concern to its designer. Some stealth aircraft (notably Lockheed F-117) have corners (that are bad for aerodynamics, but good for stealth), but a submarine must be smooth and have none, because corners make underwater noise which can be detected from miles away.

It's entirely black and has a Panau Coat of arms on it.

It was most likely destroyed by the nuke at the Selatan Oil and Gas Fields in the last mission, since it was still positioned there.

It has no propellers, so some have speculated that it has electromagnetic propulsion.

The front section of the submarine resembles a Vanguard-class ballistic missile submarine.
