Yakovlev Yak-4
The Yakovlev Yak-4 (Service names Yak-4, BB-22 (Ближний бомбардировщик, "Blizhnij Bombardirivschik", "short range bomber") was a Soviet bomber aircraft, a development of the Ya-22/Yak-2.
The Yak-4 used more powerful engines than its predecessors. The gunner/bomber position right behind pilot's turret was made non-retractable. It was a fast, good-looking light bomber, but too vulnerable for ground-attack missions. The few built were later used for night missions and high-altitude reconnaissance. The Yak-4 had two seats and two Klimov M-105R V-12 engines. It was first introduced in 1941. 90 were built.
