INTELSAT II F-1 (NORAD 2514, COSPAR 1966-096A) was a I-INT satellite that re-entered Earth's atmosphere on 18 Jul 2001, launched on 26 Oct 1966 on the INTELSAT II F-1 mission. It was operated by INTEL as part of the Int2 programme. The spacecraft was built by HSES on the HS-303 bus, with a mass of 74 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
