The U-Type Submarine is a submarine class from the Gihren's Greed series of video games.
The U-Type Submarine is a high performance Earth Federation Forces combat submarine. Developed mainly for transport, it can attack both land and sea targets.
- The Gihren's Greed video game adapts the setting of the Big Picture Book of Strategy and Tactics book, which claims the Jukon-class is based on captured EFF submarines. However, a slightly different setting is presented in Official Encyclopedia, where Zeon forces captured California Base and renovated twenty-four Type VIII Attack Submarines into Jukon-class types.
