USS Haddo (SS-255)

Commissioned as a Gato-class submarine, USS Haddo (SS-255) joined a fleet of boats that fundamentally changed the balance of power in the Pacific. The Gato-class displaced approximately 1,525 tons surfaced and carried 24 torpedoes, making them formidable commerce raiders capable of strangling Japan's maritime supply lines. The Haddo collection brings this submarine's service record to life through apparel and memorabilia built for submarine veterans, active duty crews, and military families. Every item is a connection to the real history of American undersea warfare.
