S2, E25: The Tachikoma units, through the use of a satellite, have spotted an American Empire ballistic missile submarine carrying nuclear submarine-launched ballistic missiles off the coast of Okinawa. The discovery has the Tachikoma tanks concerned; they are unable to hack into the submarine's computerized equipment to determine the vessels orders, and to make matters worse the SLBM's carried by the submarine are designed to go clear into the stratosphere before returning to Earth.
