Unbuilt Alekseyev projects

This is another special post in order to cover the unbuilt Alekseyev projects. Sadly it has not any pics because we couldn't find many info about them:

  • I-210: The original version of the I-211, powered by a pair of Tumanskii RD-20, a copy of the German BMW 003, jet engines. Never went beyond the desing board given the availability of the better Lyul'ka TR-1 engines which powered the I-211.
  • I-211S: The I-211 with backwards swept wings and tail. Unfortunately the blueprints we found for this one are not in good quality so we couldn't drawn it. 
  • UTI-212: Trainer two-seater version of the I-212. 
  • I-213: Apparently another version of the I-212. Further details are unknown.
  • I-214: An I-212 version with the tail berbette replaced by a rearwards facing radar and even heavier forward armament. Intended as a specialized night fighter.
  • I-215D: An I-215 with a by-cycle undercarriage. Built by OKB-21 order.
  • I-217: Proposed version of the I-212 with two sub-variants, one with forward swept wings and backwards swept tail and another one with backwards swept wings and backwards swept tail.
