USS Balao Conning Tower

It comes as no surprise that security is tight at the Washington Navy Yard, but few visitors expect to have to sneak past the periscope of a World War II-era attack submarine. The conning tower is positioned between a public lot and restricted base parking, looking as if it's ready to a fire off a salvo of torpedoes at unsuspecting broadsides. Luckily the vintage conning tower is anchored to a concrete pad.

The decapitated conning tower at the Navy Yard originally sat atop the USS Balao. Named after a species of little fishies, the underwater boat had a respectable but not quite awe-inspiring tour of duty in the Second World War. Its real claim to fame came when the Balao starred in the popular war comedy Operation Petticoat alongside Cary Grant.

The role itself was a little self-effacing. In the movie a Japanese bomber damages the Balao and the submariners repairing it find they have nothing but red and white anti-corrosive paint. When they patch the sub up, the gleaming new paint job is hot pink.

Audiences in 1959 screamed with delight at the prospect. The battle-hardened old sea salts of the U.S. Navy in pink? It was unthinkable. “We blushed when we asked for it and almost fainted when the Navy said okay,” the films producer explained in 1959.

The Balao was retired in the 1960s and sunk off the coast of Florida for target practice. But not before nostalgic seamen sawed off the conning tower and had it shipped to Washington. The structure was humorously painted pink for a spell, but the powers to be deep-sixed the idea and soon had it repainted standard Navy Gray.
