Later became part of a new amphibious assault squadron with four Landing Ship Tank vessels equipped with helicopter platforms. The experimental concept would allow for rapid deployment of US Marine Corps personnel and helicopter squadrons. She was reclassified LPH-4, denoting a “Landing Platform Helicopter”.
