NOAA 4 was launched on 1974 Nov 15 at 1711, by a Delta model 2310 from Vandenberg. Delta burn 1 took place at 1715. The NOAA and Delta coasted in transfer orbit from 1720 to 1808 when the second Delta burn circularized the orbit. NOAA 4 separated from the Delta at 1815, Oscar 7 separated from the Delta at 1828 and at 1847 the Delta restarted for a test burn. NOAA 4 reached a 115.0 min, 1447 x 1462 km x 101.8 deg orbit and operated until 1978.
