Hayloft (Aftrack 37)

Hayloft Aftrack 37, or Mission 7210 was an ELINT/SIGINT payload in the Aftrack program.

While most Aftrack payloads were integrated in the Agena stage, which was part of an reconnaissance satellite, the Hayloft payload used a free flying Agena stage which was used to orbit some Poppy satellites.

Hayloft acted as a testbed for the AMIE recorder and KW-26 encryptor to be used later on P-698BK payloads. The SIGINT payload was used for detecting ABM radars.
