Associated space launch

The Parcae satellites were passive ELINT satellites. MSD satellites were dispensers of triplets of ocean surveillance satellites.

GB 1 was lifted into orbit during the mission ‘Atlas H | Parcae 6A,B,C & MSD 6’, on board a Atlas H space rocket.

The launch took place on June 9, 1983, 11:23 p.m. from Space Launch Complex 3E.
