Pashinin I-21

The Pashinin I-21 (not to be confused with the Ilyushin TsKB-32, also known as "I-21") was an early 1940s Soviet fighter prototype. Designed by Mikhail M. Pashinin, the I-21 was built to incorporate lessons learned from the combat experiences of Soviet pilots during the Spanish Civil War and the Nomonhan Incident with the Empire of Japan. Despite showing promising performance, the I-21 did not get past the prototype stage, as it was felt the type did not offer a significant enough increase in capability over competitors already in production, such as the Yakovlev Yak-1 or Mikoyan Gurevich MiG-3.
