USN riverine boats were the primary victims of mines: PCF-4 (a Swift Boat) was one vessel destroyed by a river mine, nine other Swifts were destroyed by gunfire or storms. ASPB-132-3 (Assault Support Patrol Boat; also called "Alpha Boats") was sunk by a riverine mine. However, PBRs (Patrol Boat River) and numerous other Alpha Boats and Monitors (40mm & 105mm cannons) were sunk or disabled by river mines, but nearly all were salvaged (put back into service or scrapped).
The destroyer USS Higbee and light cruiser USS Oklahoma City were bombed by a NVAF MiG17 in 1972, both survived the attack. The ex-WWII USN escort aircraft carrier USS Card (redesignated US Naval Ship for transportation duties and manned by civilians) was sunk by an enemy sapper (enemy frogman) while at harbor. The vessel was raised, repaired, and put back into service.
USN ships of WWII were built of steel; USN PT Boats were built of WOOD. USN ships of WWII also fought in the Vietnam War; USN Swift Boats during the Vietnam War were built of ALUMINUM.
Tonkin Gulf "Incidents" August '64. Naval engagements between USN & NVN.
Look at the website, "Coastal Squadron One" Swift Boat Crew Directory. USN riverine forces operated on nearly all of the waterways in South Vietnam.
Nearly a dozen USN cruisers, over three dozen US destroyers, all but one US aircraft carrier, no submarines, one battleship, over 100 Swift Boats, over 200 PBRs, and over 100 Monitors & ASPBs (commonly referred to as Alpha Boats (ASPB=Assault Support Patrol Boat).
USN Seabees began operations in South Vietnam in 1954; USN mobile construction battalions consisted of about 24 officers and over 700 men and were primarily operating in I Corps (MR 1). They were primarily based at Da Nang, Hue, Phu Bai, Chu Lai, Quang Tri, and Dong Tam.
USN ships of WWII were built of steel; USN PT Boats were built of WOOD. USN ships of WWII also fought in the Vietnam War; USN Swift Boats during the Vietnam War were built of ALUMINUM.
The NVAF MiGs battled the USAF & USN air units over North Vietnam (Air War). The NVA battled the USA, USMC, and USN riverine units in South Vietnam (Ground and Riverine War).
The USAF & USN fought in NORTH Vietnam (in the skies); the US Army & USMC fought on the ground in SOUTH Vietnam.
5 IJN and 2 USN.
1. USN destroyers were attacked by NVN P4 Torpedo Boats in the Tonkin Gulf in 1964. 2. USN cruiser (USS Oklahoma City) and destroyer (USS Higbee) were attacked by NVAF MiG17s (jets) in 1972. 3. USN PCF-19 (Swift Boat) was attacked and sunk by a NVAF helicopter in 1968. 4. USN riverine boats were in constant battle in the RVN (Republic of South Vietnam).
Naval engagements between the USN and NVN in the Tonkin Gulf.
IJN & USN subs went looking for ships to sink.
The USAF & USN used to jets and jet bombers to strategically conduct an air war against North Vietnam. The USAF & USN additionally used jets and jet bombers to tactically support ground units in South Vietnam. All branches used helicopters during the war; The USAF & USN used chopppers to rescue downed airmen over North Vietnam, as well as in South Vietnam. The US Army/Marines used choppers for transport, re-supply, evacuations, and aerial gunship attacks during suppport of ground operations.
During the Vietnam War the USN flew the all weather medium A6 Intruder bomber from their carrier decks. See film: Flight of the Intruder.
The Douglas A-1 Skyraider (see film: Rescue Dawn) was a propeller driven dive bomber/torpedo bomber designed during WWII, but only saw combat in Korea and Vietnam Wars. Only the USN/USMC (?) used the A1 in Korea; the USAF/USN/USMC (?) used the Skyraider in Vietnam. About 266 A1s were lost in the Vietnam War. The Douglas A-4 Skyhawk (flown by Senator McCain) was strictly a USN/USMC jet. Nicknamed the "scooter" because it was small, easy to fly, and cheap to build and buy. Approximately 362 "scooters" were lost in the Vietnam War.
1. Air War fought by USAF & USN over the skies of North Vietnam. 2. Riverine Warfare fought by USN/South Viet Navy in South Vietnam. 3. Ground War fought by US Army/USMC: Tanks, Infantry, and Artillery.
Sometimes, for aerial insertion of Marines and the like, USN amphibious assault ships deploy Sea knight helicopters, effectively small Chinooks. They also always carry Sea Hawk choppers, the sea borne version of the Black Hawk; these are used to resupply ships and to rescue downed aviators.
