Sukhoi Su-34/32 FN. A fighter-bomber capable of flying in all weather conditions. On April 13, 1990, a prototype of the Su-27 modification, piloted by Antoly Ivanov, took off, specialized in engaging ground targets. Inside the cockpit, altitude conditions of 2,400 meters above sea level are maintained up to 10,000 meters, allowing the crew to operate without oxygen masks throughout the flight. Because the aircraft flies at extremely low altitudes under heavy anti-aircraft fire during its typical combat mission, the entire cockpit is housed within a 17mm-thick titanium box.
