General Characteristics and Role

The PTF-17 (Patrol Torpedo Fast) is a fast patrol boat of the Nasty-class, a design originally developed in Norway (where it was known as the Tjeld class) and acquired by the United States Navy in the 1960s. The PTF-17 was one of six Nasty-class boats built under license by John Trumpy & Sons, Inc. in Annapolis, Maryland. These boats were significantly larger and faster than the World War II era PT boats, and were heavily armed gunboats primarily intended for covert coastal and riverine operations during the Vietnam War as part of Operation 34A. Their high speed and agility were crucial for hit-and-run tactics against North Vietnamese coastal targets. PTF-17 is now preserved as a museum ship at the Buffalo and Erie County Naval & Military Park.

Key Feature: The high power-to-weight ratio and unique diesel engine design allowed for exceptional speed, crucial for escaping enemy coastal defenses.

Armament and Vietnam War Role

Primary Armament: The PTFs were typically heavily armed gunboats, with torpedo tubes often omitted or removed for heavier guns and unique weapons.
Typical Gun Armament: 1 x Bofors 40 mm anti-aircraft gun (aft) and 2 x 20 mm Oerlikon cannon (amidships).
Secondary Armament: Often included a « Piggyback » 81 mm mortar/0.50 caliber machine gun mount forward, and sometimes captured Soviet rockets or recoilless rifles were jury-rigged for combat missions.
Role: Used primarily by Navy Special Warfare forces for landing operations, intelligence gathering, and hit-and-run raids along the North Vietnamese coast.
