GAMBIT SV 977 (NORAD 2146, COSPAR 1966-032A) was a US satellite that re-entered Earth's atmosphere on 26 Apr 1966, launched on 19 Apr 1966 on the GAMBIT SV 977 mission. It was operated by NRO / SAFSP as part of the AFP-206 programme. The spacecraft was built by GEVF on the AFP-206 OCV bus, with a mass of 2,000 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
