Zond 9A

  1971-F06


The third N-1 launch carried a mockup L-3 spaceship, 11F81, with a dummy Blok-E engine, LK lander, Blok-I engine, and LOK orbital craft. In a new flight profile, the rocket pitched after leaving the pad, but a design error meant it was unable to return to the vertical; the Blok G/Blok D/LK/LOK section broke off and impacted 10 km from the pad, while Blok A/B/V impacted 15 km away. The plan was a lunar orbital flight.
