USS Forster (DE-334) in Vietnam

During a lull between tours, I was discussing Destroyer Escorts and Vietnam with another docent. DE's in Vietnam was the topic of last weeks blog post. He related the story of the USS Forster (DE-334) that was transferred to the Republic of Vietnam's Navy (South) and, was eventually captured and integrated into the Vietnam People's Navy (North). Another Destroyer Escort, the USS Camp (DE-251) also served in the South Vietnamese Navy but managed to sail to the Philippines in 1975. It appears that both of these DEs are no longer on active duty.

One side story of interest, in 1974 the Forster (as the RVNS Tran Khanh DU, HQ-04) played a major role during the Paracel Island Naval engagement with China. From the account: “.......The battle lasted from 10:25 AM to 11:00 AM. When HQ10 fired on the island, HQ4, HQ5, and HQ16 together fired at the enemy ships. HQ4, with two 6,000-horsepower engines, ran at full speed and fired cannons, heavy machine guns non-stop. Most of the cannons on board were rapidly firing capable. HQ4 was about 1,600 yards from the nearest enemy ship. Therefore, most of its shots hit the enemy ship. The first 5 or 6 minutes of the battle would decide the fate of engaging ships. Enemy ships sank, our ship sank. Two enemy ships and our HQ10 were put out of action during this short period. ......”

Destroyer Escorts & Vietnam

This weekend, while giving a tour of the USS Slater, I was asked about the role that Destroyer Escorts (DEs) had during the Vietnam War. This question underlines a few of the reasons for this blog. Many times during a tour I've was presented with a question that I couldn't do justice within the time limits allowed. During the typical tour you have a diverse mix of ages and interests. On a busy day tour groups can become queued (stacked) if too much time is spent at a single tour station. Because of these constraints it's important to keep answers terse.


During the tour I gave the quick answer to the question “What role did Destroyer Escorts have during the Vietnam War?”: Off the cost of South Vietnam Destroyer Escorts provided Naval Gunfire Support, and participated with Operation Market Time. Operation Market Time was the inspection of coastal vessels like trawlers and junks for contraband. The Destroyer Escorts fitted with advanced radar (DERs) were especially well suited for Operation Market Time. In WWII a few Destroyer Escorts were specialized for a high speed transport role (called APDs). During the Vietnam War these ships supported UDT, Seal Teams and Marine Units. In the mid-1960 new classes of Destroyer Escorts were built. These modern ships operated in the coastal areas near North Vietnam. These operations included PIRAZ, SAR and Yankee Station escort. Piraz was the modern evolution of Radar Picket duty. SAR was pilot rescue. Yankee Station was the operating station in the Tonkin Gulf for Aircraft Carriers.


Sometime I offer to provide additional details once a tour is over. However, by using a blog to fill out an answer, you can keep the tour moving and use the resources of the world-wide web to provide in depth answers. Rather than go into detail on the Naval Mission during the Vietnam War, I can provide a link to the US Navy History Center's detail account: By Sea, Air and Land. I can also link to specific ships that are representative of the DE's Vietnam Missions. The USS Whipple (DE-1062), a modern (post WWII) Knox-Class Destroyer Escort was deployed to the coast of Vietnam in 1972. It's duties included Piraz, C-SAR and Yankee Station Escort. The USS Haverfield (DE-393), a WWII-era Edsall-class, Destroyer Escort, was retrofitted with additional radar equipment and re-designated as a Destroyer Escort Radar Pickett (DER). Off the coast of Vietnam this ship's primary role was with the Market Time Operation. The USS Weiss (APD-135) was a support ship for UDT and Seal Teams. Regarding Naval Gunfire Support (NGFS), the National Archives maintains a database of NGFS missions off of Vietnam. A search for DE related ships will return over 3,000 missions.


The term Littoral referrers to coastal waters. Since WWII DEs, because of their lower draft, were often deployed in these waters. Based in part on these experiences of the US Navy is constructing a modern ship the Littoral Combat ship. In large part, the DE mission in Vietnam was similar to the roles outlined for the Littoral Combat Ship.
