MLP-3 was originally constructed between 1963 and 1964 as a Mobile Launcher for the Saturn V rocket, and was designated ML-1, or LUT-1. It was the first Mobile Launcher to be constructed, and was built by Ingalls Iron Works. The swing arms, which were constructed by Hayes International were added at a later date.

Space Shuttle

Following the launch of Skylab, ML-1 was the last Mobile Launcher to be converted for use by the Space Shuttle. The Launch Umbilical Tower and Milkstool were dismantled and placed into storage, and the base of the launch platform was modified to accommodate the locations of engines on the Shuttle. The platform was redesignated MLP-3.

In total, MLP-3 has been used for twenty nine Shuttle launches, starting in 1990. It is the least used of the three Mobile Launcher Platforms.
