The Parcae satellites were passive ELINT satellites. MSD satellites were dispensers of triplets of ocean surveillance satellites.
SSB was lifted into orbit during the mission ‘Atlas H | Parcae 5A,B,C & MSD 5’, on board a Atlas H space rocket.
The launch took place on Feb. 9, 1983, 1:47 p.m. from Space Launch Complex 3E.
