Launch Complex 3 (LC-3) is a deactivated US Air Force launch site southeast of SLC-36 on Cape Canaveral, Florida at Cape Canaveral Air Force Station. It was constructed, with launch complexes 1, 2, and 4, in the early 1950s for the Snark missile program.
It was formerly used to launch Bumper, BOMARC, UGM-27 Polaris, and Lockheed X-17 missiles. The pad was also the site of the first launch from Cape Canaveral, a Bumper rocket on July 24, 1950. The site also served as a medical support facility during Project Mercury.
