Gant hugs the eastern slopes of the Ural Mountains to evade Soviet acoustical listening stations, but is spotted and fired upon by a SAM station equipped with infrared search and track sensors. Gant decoys the incoming infrared homing missiles by destroying a Badger aircraft that chances upon the scene. Gant escapes, but the Soviets are now alerted to his heading and redirect their search efforts to the Barents Sea area of the Arctic. A Soviet missile cruiser spots Gant and attacks, firing missiles and attempting to launch a helicopter. Gant destroys the helicopter, but he is now nearly out of fuel so he climbs to stretch out his range. His receiver then detects the homing signal, directing Gant to an ice floe. Landing, Gant finds an American submarine bearing kerosene fuel and using the floe as an ad-hoc runway. The Americans rearm and refuel the Firefox, giving Gant the necessary range, but barely finish before the arrival of a Soviet submarine.
