Fast Patrol Craft
Encyclopedia
Patrol Craft Fast, also known as Swift Boats, were all-aluminum, 50 feet (15.2 m) long, shallow-draft vessels operated by the U.S. Navy, initially to patrol the coastal areas and later for work in the interior waterways as part of the Brown Water Navy to interdict Vietcong movement of arms and munitions, transport Vietnamese forces and insert SEAL teams for counterinsurgency (COIN) operations during the Vietnam War
Vietnam War
The Vietnam War was a Cold War-era military conflict that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. This war followed the First Indochina War and was fought between North Vietnam, supported by its communist allies, and the government of...

Conception

The Swift Boat was conceived in a Naval Advisory Group, Military Assistance Command Vietnam (NAVADGRP MACV) staff study titled "Naval Craft Requirements in a Counter Insurgency Environment," published 1 February 1965. It noted that "COIN water operations are difficult, demanding, and unique. A prevalent belief has been that COIN craft can readily be obtained from existing commercial and naval sources when needed. Unfortunately, no concerted effort has been made to develop COIN craft specifically suited to perform the many missions needed to combat insurgent activities."

The study went on to list characteristics of the ideal patrol craft:
  • Reliable and sturdy
  • Non-wooden hull, with screw and rudder protection against groundings
  • Self-sufficient for 400 to 500 mile (600 to 800 km) patrol
  • Speed of 20 to 25 knots (37 to 46 km/h)
  • Small high-resolution radar

Mark I

The Swift Boats had welded aluminum hulls about 50 feet (15 m) long with 13 ft (4 m) beam, and draft of about five feet (1.5 m). They were powered by a pair of General Motors 12V71"N" Detroit marine diesel engines rated at 480 hp (360 kW) each, with a design range from 320 nautical miles (592.6 km) at 21 knots (590 km at 39 km/h) to about 750 nautical miles (1,389 km) at 10 knots (1390 km at 19 km/h). The normal complement for a Swift Boat was six: an officer in charge, a boatswain, a radar/radioman, an engineer, and two gunners. In 1969 the crew was supplemented with a Vietnamese trainee.

The first two PCFs were delivered to the Navy in late August 1965. The original water taxi design had been enhanced with two .50 caliber M2 Browning machine guns in a turret above the pilot house, an over-and-under .50-caliber machine gun – 81 mm mortar combination mounted on the rear deck, a mortar

The original order for 50 boats was followed shortly by an additional order for 54 more Mark I's.

Mark II & III

In the latter half of 1967, 46 Mark II boats, with a modified deck house set further back from the bow. The newer boats also had round port holes (replacing larger sliding windows) in the aft superstructure. From 1969 through 1972, 33 Mark III's, which were a larger version of the Mark II's, arrived in Vietnam.

 area in the southern tip of Vietnam. The boat's missions included patrolling water ways, searching water traffic for weapons and munitions, transporting Vietnamese marine units and inserting Navy SEAL teams. Coming back down river was always the more dangerous part of the mission. The passage of a patrol assured their eventual return, as the boat had to make its way back to base. The ambush was usually set at a river bend or in a narrow canal that restricted the maneuverability of the boats. The boats were attacked with recoilless rifles

, .50 caliber machine guns and AK-47s, often fired from behind earthen bunkered positions. Though most cruising and patrolling was done at 8 to 10 knots, the boats could reach a top speed of 32 knots. If attacked the boats would accelerate out of harms way, turn and then return as a group, firing as many of their .50 caliber machine guns as they could bring to bear as they powered past the ambush point, then returning back across as many times as needed to reduce the ambushers. Engagements were brief, with the ambushers often slipping off into the undergrowth when the boats located the source of attack and began to concentrate their return fire. Casualties taken among the river crews were high, as were casualties suffered among the Vietcong, though the discovery of new graveyards was one of the few ways to confirm Vietcong losses.

The first Swift Boat to be lost during the war was PCF-4, which was lost to a mine in 1966. Three others were lost in rough seas, trying to re-enter the treacherous mouths of the Cua Viet River near the DMZ

The Events of June 1968

In June 1968, PCF-19 and PCF-12 were patrolling near the DMZ (17th parallel) when they were attacked by hovering aircraft at night time. Within minutes, PCF-19 had disappeared from an explosion, and PCF-12 commenced a running gun battle with its .50 caliber machine guns for well over an hour with those "hovering lights." During this battle, PCF-12 had been continuously radioing that they were under attack by unidentified aircraft, i.e. hovering aircraft. The response was a continuous one, "no friendly aircraft in the area". Further radio traffic informed PCF-12 that US Forces had suspended all flying operations within PCF-12's area, in order to isolate the problem; especially rotor-wing aircraft (helicopters).

But the Swift Boat was still in contact (still engaged with the enemy). Hours elapsed, but still in darkness, US jet aircraft responded to PCF-12's firefight, but bypassed them and headed for the Australian destroyer

 USS Boston (CAG-1), the U.S. jets fired rockets killing two Australian sailors, and slightly damaging the Hobart, and the USS Boston. Parts of the recovered rockets had US data on them identifying them as American. The hovering aircraft had also been seen by US Marines on shore, near the DMZ, on the South side of the border. When all reports had been submitted, the attacks on the two allied warships were attributed to the US attacking fixed-wing aircraft (friendly fire

), and also for attacking PCF-12, and destroying PCF-19.

A primary complication, that helped to make the above conclusion, is that the battle between the Swift Boats and the unidentified hovering aircraft started between midnight and 0100 hours on 16 June, and the attacks (fratricide) on the Boston and Hobart occurred during the same time frame, only on the 17th of June. These were two separate dates, and, in reality, two separate incidents. When completed (the reports) both events had somehow been merged into one incident; again, fratricide. It had been theorized, by both officers and men (U.S. Army, USMC, USN) that the, "NVA helos were flying artillery...", etc. to Tiger Island, located just off the North Vietnamese coast. However, it goes beyond theory, when official reports, such as OIC, PCF-12's Combat After Action Report dated "20 OCT 1967" (1968?) for "Market Time Patrol", "151130H JUN-161130H JUN 1968", mentions in part "...enemy held Tiger Island...possible base of operations for North Vietnamese military..." and "under constant air attack from all angles Helo...gunners ordered to fire the .50 caliber guns at any and all air contacts..." There were more than enough declassified official reports that mention "enemy aircraft" to conclude that the loss of PCF-19 was due to North Vietnamese helicopters. It is important to note however, that as of 2006, PCF-12 and PCF-19 were still carried by the US Navy as attacked/lost from friendly fire.

In Training

The most frequent training area for the Mare Island units was the marshland that forms the northern shoreline of San Francisco Bay. This area, now known as the Napa-Sonoma Marshes State Wildlife Area, was also used by U.S. Navy Reserve unit PBRs (Patrol Boat, River

 was scheduled for Base Closure. During those years in which the Swifts and PBRs were operating, motorists traveling along Highway 37 from Vallejo, which passes Mare Island, to the Bay Area would often see the Riverine Boats making their way through the various sloughs of the current wildlife area. U.S. Naval Riverine Training is still authorized in the waters of the State Wildlife Area, and portions of the TV History Channel Series Gunboats of Vietnam, were filmed there.
