Sealab I

Date:
1964

SEALAB I was a 40' x 9' cylinder without windows. It housed four aquanauts for eleven days during which time they performed physical and biological experiments with ultrasonic beacons, current meters, and an anti-shark cage. It was first tested in the waters off Panama City, Florida, in 1964 and then moved 26 miles southwest of Bermuda and lowered to a depth of 200 feet. SEALAB I tested and proved the concept of saturation diving and laid the groundwork for SEALAB II and III.

Sealab II Endbell

SEALAB II was designed, built, and outfitted at Hunter's Point Naval Shipyard in San Francisco. The Navy lowered it to the sea floor off La Jolla, California, in the fall of 1965.  It was designed to house ten men at a depth of 200 feet for 30 days.  The habitat was 50’ long and 12’ in diameter, and included four separate areas: entry, laboratory, galley, and living spaces. Entry while on the ocean floor was from below the habitat, with divers emerging into the pressurized habitat through an open moon pool.
