Design of the catapult-launched winged rocket was completed on 2 August 1936. Two tests of the catapult using a mock-up of the rocket in November 1936 were failures - after release the rocket would contact the sled and crash. It was decided the missile would be air-launched instead, and captive-carry tests of a mock-up on a TB-3 bomber were successful on 27 May 1938. Two days later Korolev was injured in an explosion during a firing test of the rocket on a stand. Korolev, denounced by Glushko, was arrested a month later and imprisoned.
However development continued in his absence. On 19 January 1939 it was decided not to use Glushko's ORM-65 engine in the 212 due to continuing explosions and control-system failures. At this time the missile was redesigated the 803. There are some reports that the remaining team members conducted two flight tests of the 212 in 1939, neither of them successful due to control system failures. The project was then abandoned.
