Index Soviet submarine S-99

The S-99 (С-99) experimental submarine was the only ship of the Soviet Project 617 submarine class (NATO reporting name: Whale class) that the Soviet Union built during the early Cold War and the only Soviet submarine which had a Walter engine fuelled by high test peroxide (HTP). [1]

Air-independent propulsion

Air-independent propulsion (AIP) is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel).

Cold War

The Cold War was a state of geopolitical tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others).

Type XVII submarine

The Type XVII U-boats were small coastal submarines that used Hellmuth Walter's high-test peroxide propulsion system, which offered a combination of air-independent propulsion and high submerged speeds.
