A PT valtis (trumpinys iš patrulinio torpedinio laivo) buvo torpedomis ginkluotas greito puolimo laivas (MTB), kurį Antrojo pasaulinio karo metais naudojo Jungtinių Valstijų karinis jūrų laivynas. Jis buvo mažas, greitas ir nebrangus statyti, vertinamas dėl savo manevringumo ir greičio, tačiau karo pradžioje trukdė neveiksmingos torpedos, ribota ginkluotė ir palyginti trapi konstrukcija, kuri kai kuriuos variantus apribojo pakrančių vandenimis.

General Characteristics and Role
PT-617 was one of the late-war, high-production Elco 80-foot class Patrol Torpedo boats of the US Navy. PT boats were small, fast, and lightly armed vessels designed for high-speed hit-and-run attacks on larger enemy ships, especially at night. By the time PT-617 was built, the class had evolved significantly, incorporating heavier armament and better armor protection based on combat experience in the Solomon Islands and the Pacific. The 80-foot Elco design was the largest and most widely produced US Navy PT boat, known for its powerful engines and wooden construction, which kept the weight down while retaining high performance.

- Anti-Aircraft: 2 x twin .50 cal (12.7 mm) machine guns in powered turrets.
- Depth Charges: Typically carried a selection of Mark 6 depth charges for anti-submarine duties, or sometimes rocket launchers.
Service and Legacy
- Service Theater: PT-617 served in the Pacific Theater, primarily operating in the Philippines and later in the Okinawa campaign.
- Mission Profile: Primarily used for interdiction, sinking barges and small coastal vessels (“Barge Busters”), shore bombardment, and rescue operations.
- Post-War Status: Many late-war PT boats, including PT-617, were quickly decommissioned after the war and later sold or scrapped as they were highly specialized wartime assets.
- Preservation Note: PT-617 is notable today for being the only remaining operational 80-foot Elco PT boat in the world, preserved and restored by the Battleship Cove museum in Fall River, Massachusetts, alongside the USS Joseph P. Kennedy, Jr. (DD-850).
