Complexes 40 and 41 were constructed as part of a $39 million project to build an Integrate-Transfer-Launch (ITL) facility at the north end of Cape Canaveral in the early 1960s. Both complexes were originally designed to support Titan IIIC space missions, which began from Complex 40 on 18 June 1965. Over the next three decades, the complexes supported a wide variety of military space missions involving Titan IIIC, Titan 34D and Titan IV vehicles. Between June 1990 and June 1993, Complex 40 was almost completely rebuilt under a $425 million renovation project. Complex 40 supported its first Titan IV/Centaur launch on 7 February 1994. By the end of October 1998, the complexes had supported a total of 72 Titan IIIC, Titan IIIE, Titan 34D and Titan IV missions.

The purpose of the ATS-6 flight experiment was to demonstrate north-south stationkeeping of a geosynchronous satellite using two cesium ion engine systems. Thruster development tests included a life test of 2614 hours and 471 cycles. Thruster input power was 0.15 kW, which resulted in a thrust of 4.5 mN at a specific impulse of 2500 s. One of the ion engines operated for about one hour and the other for 92 hours. Both of the engines failed to provide thrust on restart due to discharge chamber cesium flooding. The feed system flooding problem caused overloading of the discharge and high voltage power supplies. This failure mechanism was verified through a series of ground tests. However engine operation demonstrated an absence of EMI related to spacecraft systems, verified predictions of spacecraft potential with engines operating, and demonstrated compatibility with the spacecraft's star tracker. It was found that the ion engines or just the neutralizer could discharge large negative spacecraft potentials at all times.
