KH-4A Mission 1036 (CORONA 111) saw the introduction of a new launch vehicle, the Long Tank Thrust Augmented Thor Agena D. The LTTAT, also known as Thorad, was delivered by McDonnell Douglas to USAF in June of 1966, and took off from Vandenberg on Aug 9, placing the KH-4A payload into a retrograde 100 degree inclination orbit. The KH-4A mission had an unusually long duration, with SRV-1 recovered after 7 days and and SRV-2 operating for a further 6 days before recovery. This mission may be the first J-2 model,although the J-2 designation was not used in most documents. The J-2 proposal, reportedly not approved, used Thorad/Agena, had a 14 day lifetime, and could incorporate the OAS orbit adjust system kit. All of these enhancements apply to the later J-1 missions.
