Lauerman describes service aboard the submarines USS
Tambor (1941–1942), USS
Halibut (1942–1943), USS
Sealion (1943–1944), and USS
Cabrilla (1944–1945) in the Pacific and the Aleutians during World War II. After the war, he served aboard USS
Argonaut (1948–1950), a training submarine based at New London, Connecticut, and aboard USS
Mount McKinley (1960–1962), an amphibious commandship. Lauerman discusses submarine warfare, unity of a ship's crew, and comparison of the World War II submarine with its modern counterpart.
Of particular interest in the interview are techniques used by submarines to find and destroy Japanese ships and to escape Japanese detection, encounters with Russian submarine crews at Dutch Harbor, an incident involving the USS
Erie in Ecuador's political affairs, the rescue of Australian POWs, "wolfpacking," and training techniques used in 1948-1950 involving marines being carried on board submarines.
