[5] In September 2015, pad modifications began to support human spaceflight with the Boeing CST-100 Starliner.

Titan vehicles were assembled and integrated with their payloads on mobile platforms in separate buildings, then moved by rail to one of two launch pads.

[11] The facilities were completed in 1964, and the first launch from LC-41 was of a Titan IIIC carrying four separate payloads on 21 December 1965.

[13] In 1986 the existing mobile service tower (MST) and umbilical tower (UT) were both stripped down to their main structural components which were then refurbished, modified, and added to, as part of Martin Marietta's "tear-out and refurbish" contracts which modified and prepared the launch pad for the Titan IV rocket.

The IUS upper stage failed to separate, leaving the payload stranded in a useless GTO orbit.
