A6M Zero
History
The Yakovlev Yak-3 (Russian: Яковлев Як-3) was a single-engine, single-seat World War II Soviet fighter. Robust and easy to maintain, it was much liked by both pilots and ground crew. One of the smallest and lightest combat fighters fielded by any combatant during the war, its high power-to-weight ratio gave it excellent performance and it proved to be a formidable dogfighter.
The origins of the Yak-3 went back to 1941 when the I-30 prototype was offered along with the I-26 (Yak-1) as an alternative design. The I-30, powered by a Klimov M-105P engine, was of all-metal construction, using a wing with dihedral on the outer panels. Like the early Yak-1, it had a 20 mm (0.79 in) ShVAK cannon firing through the hollow-driveshaft nose spinner as a motornaya pushka (моторная пушка - Literally: 'Motor Cannon'), twin 7.62 mm (0.300 in) synchronized ShKAS machine guns in cowling mounts and a ShVAK cannon in each wing.
During the Battle of Stalingrad, Luftwaffe fighters exhibited significant speed, climb rate, and armament advantages over those of the VVS. The Yak-1 then in service was understood to be in urgent need of a modernization were it to fight on equal footing against the latest models of German fighters, as well as better energy retention and higher firepower.

The Mitsubishi A6M "Zero" is a long-range carrier-based fighter aircraft formerly manufactured by Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and was operated by the Imperial Japanese Navy from 1940 to 1945. The A6M was designated as the Mitsubishi Navy Type 0 carrier fighter (零式艦上戦闘機, rei-shiki-kanjō-sentōki), or the Mitsubishi A6M Rei-sen. The A6M was usually referred to by its pilots as the Reisen (零戦, zero fighter), "0" being the last digit of the imperial year 2600 (1940) when it entered service with the Imperial Navy. The official Allied reporting name was "Zeke", although the name "Zero" (from Type 0) was used colloquially as well.
