The ELINT satellites known for decades only as "Heavy Ferrets" are now known to be a program associated with the Samos (Satellite and Missile Observation System) project. This first series of Heavy Ferrets was called Samos-F2. The exact objective of these satellites is still unknown.
Only the first Samos-F2 has been identified for sure, but based on the fact, that only four satellites of this series were built and only three more Agena-B based Ferrets were launched, the remaining flights could be tentatively identified.
Some satellites carried secondary payloads mounted on the satellite:
This series was followed by the Samos-F3 series of ELINT satellites.
