"Enterprise" returned to the South China Sea from 12 September 1972 with CVW-14 onboard. On 18 December 1972, the United States resumed bombing campaigns above the 20th parallel under the name Linebacker II. During Linebacker II operations, "Enterprise" and other carriers on station reseeded the mine fields in Haiphong harbor and conducted concentrated strikes against surface-to-air missile and anti-aircraft artillery sites, enemy army barracks, petroleum storage areas, Haiphong naval and shipyard areas, and railroad and truck stations. Navy tactical air attack sorties under Linebacker II were centered in the coastal areas around Hanoi and Haiphong. There were 705 Navy sorties in this area during Linebacker II. Between 18 and 22 December, the Navy conducted 119 Linebacker II strikes in North Vietnam, with the main limiting factor on airstrikes being bad weather. In December 1972, the North Vietnamese returned to the peace table and Linebacker II ended. In January 1973, the Vietnam cease-fire was announced and American carriers ceased all combat sorties into North and South Vietnam. From 28 January 1973, aircraft from "Enterprise" and "Ranger" flew 81 combat sorties against lines-of-communication targets in Laos. The corridor for overflights was between Huế and Da Nang in South Vietnam. These combat support sorties were flown in support of the Laotian government, which had requested this assistance. Laos had no relationship with the ceasefire in Vietnam. "Enterprise" completed its deployment on 12 June 1973.
