English: Hwachon Dam Air Strikes, Korea, April-May 1951: Torpedo attack on the Hwachon Reservoir dam by Douglas AD Skyraiders of Attack Squadron 195 (VA-195) from USS Princeton (CV-37), 1 May 1951. This successful strike, and earlier bomb attacks by U.S. Navy and U.S. Air Force planes, were made to deny the enemy the tactical use of controlled flooding on the Pukhan and Han rivers. Torpedoes were used after bombs failed to achieve the desired results. They destroyed one flood gate and partially destroyed another. This was the only Korean War use of torpedoes. The Hwachon Reservoir was later recaptured by U.N. forces.
