米格-21战斗机（俄文：МиГ-21，英文：MiG-21， 北约 代号：Fishbed，译文：鱼窝），是苏联一型超音速喷气式 第二代战斗机。 米格-21战斗机采用单座三角翼气动布局，安装一台涡喷发动机，是根据 朝鲜战争 中喷气战斗机空战经验研制的，主要任务是高空高速截击、侦察，也可用于对地攻击 [1]，特点是轻巧、灵活、爬升快、跨音速和超音速操纵性好，火力强，其中高空高速性能被摆在了首要位置 [2]。

米格-21F-13型是米格-21家族的早期型号，她衍生自米格-21F型。 该机在其基础上拆除了一门NR-30型机炮，但具备携带R-3S（北约代号AA-2A环礁）红外制导空空导弹的能力。

The MiG-21 soon became the standard clear-air interceptor for the Soviet Air Forces. By adding radar in the MiG-21PF and more powerful engines and blow-up flaps in the MiG-21S, the aircraft became a multi-role fighter.

The MiG-21 Fishbed F is a short-range, supersonic, day fighter-interceptor and the first major production version of the popular MiG-21 series. It is but one of many versions of this aircraft that have served in the air arms of many nations around the world.

It was designed in response to Korean War needs for a short-range interceptor and light strike fighter. First flown in 1955, the MiG-21 was the first Soviet plane to reach Mach 2. For three decades, variants of the MiG-21 went head-to-head with the F-4 Phantom and other American-made fighters in Cold War-related conflicts worldwide.

The MiG-21 was Russia's first truly modern second-generation jet fighter. The Russian Central Aerohydrodynamic Institute (TsAGI) developed a unique "tailed delta" configuration with a very thin delta wing.
