Apollo Command Module Boilerplate

Apollo Command Module Boilerplate

Many of us remember the excitement of the Apollo missions that landed a dozen Americans on the Moon more than 50 years ago. The Apollo Command Module was the only part of the massive, skyscraper-sized Saturn V rocket that returned to Earth at the end of each flight. You can recognize an enlarged version of the Command Module’s cone shape in today’s Lockheed Martin Orion spacecraft and the Boeing Starliner.

This artifact looks very much like an actual Apollo Command Module, but it never carried astronauts into space. It is a boilerplate—a simplified metal model created to test specific aspects of the real spacecraft, such as water landings, launch abort escape rockets, or recovery systems. It duplicates the size, weight, shape, and center of gravity of the actual vehicle.

This particular boilerplate is BP-1101A. NASA used it for flotation tests in the Gulf of Mexico in July, 1965. After some modifications, NASA used it again for additional ocean testing in 1966 and 1967. In most photos of Apollo spacecraft floating in the ocean you can see large round balloons near the top. They pull the spacecraft right-side-up if it capsizes, and they were tested on this very boilerplate.
