Existing comment: Stealthy Submarine:
Russia's Kilo submarine is one of the quietest diesel subs in the world. It's said to detect enemy ships from a range three or four times greater than it can be detected itself. Equipped with six torpedo tubes, a high-speed computer, and sophisticated sensors, the Kilo is designed for combat as well as patrolling and reconnaissance missions.

In 1993, Iran purchased two Kilos from Russia -- a potential threat as tracking equipment would not recognize them as enemy submarines.
