Wild Bill 2, 4 (Aftrack 27, 33)

Wild Bill 2 and 4 (Aftrack 27/Mission 7202 and Aftrack 33/Mission 7216) were ELINT/SIGINT payloads in the Aftrack program.

Purpose of the Wild Bill ELINT packages was to search for signals from the HEN HOUSE ABM/AES radar that had been seen under construc- tion at Sary Shagan on images obtained by photographic reconnaissance satellites.

While most Aftrack payloads, including Wild Bill, Wild Bill 1 and Wild Bill 3, were integrated in the Agena stage, which was part of an reconnaissance satellite, the Wild Bill 2 and Wild Bill 4 payloads used a free flying Agena stage used to orbit some Poppy satellites.
