Vostok 7 was an eight day manned flight that was originally planned for the last quarter of 1963. Opposition by the Ministry of Defence led to it being cancelled, only to be resurrected and scheduled for June 1964. All remaining Vostok 3KA 3 missions were canceled in the spring of 1964 in favor of Vostok 3KV 4 and 3KD missions. References: Encyclopedia Astronautica. Russian Space Web Wikipedia.
