The "Haskells" were very active in the World War II Pacific Theater of Operations, landing Marines and Army troops and transporting casualties at Iwo Jima and Okinawa. Ships of the class were among the first Allied ships to enter Tokyo Bay at the end of World War II, landing the first occupation troops at Yokosuka. After the end of World War II, most participated in Operation Magic Carpet, the massive sealift of U.S. personnel back to the United States. A few of the "Haskell"class were reactivated for the Korean War, with some staying in service into the Vietnam War.
