Associated space launch

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

JD 2 was lifted into orbit during the mission ‘Atlas H | Parcae 7A,B,C & MSD 7’, on board a Atlas H space rocket.

The launch took place on Feb. 5, 1984, 6:44 p.m. from Space Launch Complex 3E.
