Space Data Sergeant-Hydac / Talos-Sergeant-Hydac

Between 25 February and 12 March 1981, the U.S. Air Force's BMO (Ballistic Missile Organization) launched three Sergeant-Hydac two-stage soild-fueled rockets on HAVE SLED test missions. HAVE SLED was a program to to collect data for algorithms to discriminate ICBM reentry warheads from decoys. Between 16 December 1983 and 2 February 1984, three Talos-Sergeant-Hydac three-stage rockets were launched under program HAVE SLED II, which presumably had a similar purpose as the original HAVE SLED. Talos-Sergeant-Hydac rockets were also used in the 1987/88 time frame for the HAVE JEEP VII test series.
