Failed · Failure
An attempted Venus flyby mission NSSDCA carries only on its list of tentatively identified missions and launch failures, describing it as possibly similar to the Venera 2 flyby mission launched two weeks earlier. It is believed the SL-6/A-2-e launcher failed. Its three NSSDCA pages disagree on the date: the two chronologies print 23 November 1965 and the tentative-launches page prints 26 November.

Launch
Lost when the launcher failed
NSSDCA's tentative-launches page dates this flight to 26 November 1965 from Tyuratam (Baikonur Cosmodrome) and records that it is believed the SL-6/A-2-e launcher failed. The three NSSDCA pages disagree on the date and the disagreement is recorded rather than resolved: both the Chronology of Lunar and Planetary Exploration and the Chronology of Venus Exploration print Venera 1965A - 23 November 1965 - Attempted Venus Flyby (Launch Failure).
