“Another story on what most Americans don’t know about the Navy’s role in the Vietnam War?”
Most Americans probably believed that by 1972, the war in Vietnam was essentially winding down. However, for the U.S. Navy in Vietnam, 1972 would prove to be a busy year of conducting numerous and dangerous combat operations. On May 8, 1972, President Richard Nixon ordered the mining of Haiphong Harbor’s approaches and channels. Nixon defended his escalation of the air and sea war as crucial to cut off the flow of supplies to North Vietnamese troops fighting in the South and to protect the lives of American forces still in Vietnam. Also, Nixon contended that the raids and the mining were calculated to pressure the North Vietnamese government into resuming critical negotiations to achieve peace in Vietnam.1
President Nixon’s orders required the U.S. Navy’s 7th Fleet to put together two joint-operations. The task of one operation would be the aerial seeding of mines at the approaches and channel into Haiphong Harbor; the task of the second operation would be to suppress gunfire from the North Vietnamese shore batteries located principally on Cat Ba Island and along the Do Son Peninsula. The two operations were called “Operation Pocket Money” and “Operation Custom Tailor.”
“Operation Pocket Money.” An aerial mining campaign conducted by U.S. Navy Task Force 77 against North Vietnam on May 9, 1972 (Vietnam time). The purpose was to halt or slow the transportation of supplies and materials for the Nguyen Hue Offensive or Easter Offensive, an invasion of the Republic of Vietnam (South Vietnam), by forces of the People’s Army of Vietnam (PAVN), launched on March 30. Pocket Money was the first use of naval mines against North Vietnam. Three A-6 Intruders carried 1,000-pound (450 kg) Mark 52 magnetic mines to be dropped in Haiphong’s inner channel; all Mark 52-2 mines were set with 72-hour arming delays, in order to permit merchant ships time for departure or a change in destination consistent with the President’s public warning. Six Navy A-7 Corsair IIs carried 500-pound (230 kg) Mark 36 acoustic mines that were dropped in the outer portion of the channel. Each plane carried four mines.3
To support Task Force 77 (Operation Pocket Money), at daylight on May 9, Task Unit 77.1.2 a destroyer strike force struck the Haiphong Harbor air defense batteries with a 30-minute bombardment from their 5-inch (127mm) guns, which preceded the aerial mining. The strike force consisted of USS Richard S. Edwards (DD 950), USS Berkeley (DDG 15), USS Buchanan (DDG 14) and USS Myles C. Fox (DD 829). 3
Additionally, guided missile cruisers USS Long Beach (CGN 9) and USS Chicago (CG-11) had been moved north from the PIRAZ2 station off Hon Mat to within 40 miles of Haiphong to protect aircraft mining Haiphong Harbor at low altitude. These cruisers patrolling offshore were given a free-fire zone for their Talos missiles to engage defending MiG fighters approaching the coast from near Hanoi. Chicago set general quarters at 0840, and within minutes launched two RIM-8 Talos missiles at two MiGs in a holding pattern awaiting air control vectors on the approaching A-6 Intruders and A-7 Corsairs. One MiG was reported destroyed. 3
“Operation Custom Tailor.” Early on May 10, another strike force, which was a cruiser/destroyer strike force conducted another daring raid on Haiphong, to suppress hostile shore gun batteries to also enable the ongoing aerial mining by Task Force 77’s aircraft. Between the two operations, it was a history-making strike that involved the most formidable cruiser/destroyer fleet in the Western Pacific since World War II. During the strike, military targets within four miles of Haiphong were hit and enemy opposition initially was heavy.
The ships now making up TU 77.1.2 were two Gearing class destroyers USS Hanson (DD 832) and USS Myles C. Fox (DD 829); a guided missile destroyer USS Buchanan (DDG 14); an 8-inch cruiser USS Newport News (CA 148); two 6-inch gun missile cruisers USS Providence (CLG 6) and USS Oklahoma City (CLG 5).
At around 0200 on May 10, the commanding officer of Newport News, Captain Walter F. Zartman, ordered the formation into a line abreast, Hanson to the far left, then Providence, Newport News, Oklahoma City, and Buchanan.
USS Myles C. Fox (DD 829) was ordered farther to the northeast to act as a blocking element in case of enemy patrol-boat activity and to cover the rear of the formation when it would eventually turn to south of west and onto the formation’s firing course.
At 0345, all five warships turned to the firing course 240 degrees (True), roughly parallel to the longitudinal axis of the airfield on Cat Ba Island. At the extreme range of Newport News’s 8-inch guns, the Cat Ba military complexes were the raid’s primary targets. The completely darkened warships commenced firing together at 0347.4
Seventy-seven massive 8-inch rounds and 40, 5-inch rounds from Newport News slammed into the military installations around Cat Ba. Meanwhile hundreds of rounds were fired from the two light cruiser’s 6-inch guns as Hanson’s 5-inch/38 caliber and Buchanan’s 5-inch/54 caliber guns pounded on enemy targets along the Do Son Peninsula. Hanson’s gunfire is credited with suppressing the enemy shore batteries, allowing the cruisers to concentrate their fire on assigned targets.5,6
During the raid, USS Hanson entered Haiphong Harbor to suppress hostile shore batteries while enabling Task Force 77 aircraft to continue mining the Haiphong Harbor entrance. This made USS Hanson the last American warship to enter Haiphong Harbor during the Vietnam War and the last one out.
When North Vietnamese shore batteries opened up, effective counter-battery fire from the combined cruiser-destroyer force silenced them. In less than thirty minutes, the entire action was over. Gunfire from the shore batteries had been somewhat sporadic and none of the ships were hit. It is safe assumption that the overwhelming gunfire from the cruisers and destroyers caused most of the North Vietnamese gunners to run for cover and by the time they re-manned their guns, the task group was retiring out to sea. However, the North Vietnamese fired numerous 152-mm shells at the column of ships as they steamed past in the darkness, and the crews in all the ships heard and felt the explosive blasts from the enemy’s incoming rounds.
Operation Pocket Money, was the beginning of a mining campaign that over the next eight months planted over 11,000 Mark 36 type destructor and 108 special Mark 52-2 mines. It is considered to have played a significant role in bringing about an eventual peace arrangement, particularly since it significantly hampered North Vietnam’s ability to continue receiving war supplies7….To read “Striking Eight Bells,” use one of these links to booksellers: Amazon.com: Books, Barnes and Noble Booksellers, BAM –Books A Million and Smashword.com eBooks.
- PIRAZ is a U.S. Navy acronym for Positive Identification Radar Advisory Zone. The zone is defined by the air search radar coverage of a ship patrolling a designated PIRAZ station. PIRAZ ships carried long-range RIM-2 Terrier or RIM-8 Talos surface-to-air missiles to defend their stations. A PIRAZ station was established in the westernmost portion of the Gulf of Tonkin where air search radar coverage might extend over North Vietnam and the U.S. air-strike routes.
