Operation Linebacker - Paris Peace Talks and Conclusion

Paris Peace Talks and Conclusion

For more details on on the negotiations, see Paris Peace Talks.

The stalled offensive in the south and the devastation in North Vietnam had helped to convince Hanoi to return to the bargaining table by early August. The meetings produced new concessions from Hanoi which promised to end the deadlock that had plagued negotiations since their inception in 1968. Gone were Hanoi's demands for the ouster of South Vietnamese President Nguyễn Văn Thiệu and his replacement by a coalition government in which the National Liberation Front would participate. The diplomatic impasse was broken and Nixon ordered a halt to all bombing above the 20th parallel on 23 October. This once again placed Hanoi and Haiphong off-limits, and halted Linebacker operations.

Air Force historian Earl Tilford has written that Linebacker was "a watershed in aerial warfare...it was the first modern aerial campaign in which precision guided munitions changed the way in which air power was used." It succeeded, where Rolling Thunder had failed, he claimed, for three reasons: President Nixon was decisive in his actions and gave the military greater latitude in targeting; American airpower was forcefully and appropriately used; and the immense difference in the technology utilized made Linebacker the first bombing campaign in a "new era" of aerial warfare.

During and immediately following the PAVN offensive, U.S. Air Force, Navy, and Marine Corps aviators had flown 18,000 sorties in the four northern provinces of South Vietnam and dropped 40,000 tons of ordnance in the defense of An Loc. Between March and May, B-52 sortie rates had climbed from 700 to 2,200 per month and the big bombers had dropped 57,000 tons of bombs in Quang Tri Province alone. During Freedom Train and Linebacker proper, B-52s had dropped 150,237 tons of bombs on the north while Air Force and Navy tactical aircraft had flown 1,216 sorties and dropped another 5,000 tons of ordnance.

From the beginning of Freedom Train in April to the end of June 1972 the United States lost 52 aircraft over North Vietnam: 17 to missiles; 11 to anti-aircraft weapons; three to small arms fire; 14 to MiGs; and seven to unknown causes. During the same time period, the Republic of Vietnam Air Force lost ten aircraft. 63 North Vietnamese aircraft were destroyed during the same time period. North Vietnam claimed that it had shot down 651 aircraft and sunk or set on fire 80 U.S. warships during the operation.

Linebacker had played a crucial role in blunting the northern offensive by drying up its vital sources of supply. PAVN had evolved into a conventional military force, and such a force depended upon a complex logistical system, which made it vulnerable to aerial attack. By September, imports into North Vietnam were estimated at 35 to 50 percent below what they had been in May, bolstering claims that the campaign had been successful in its interdiction effort. Air Force General Robert N. Ginsburgh, of the Office of the Secretary of the Air Force, summed up the attitudes of U.S. commanders by remarking that Linebacker had "a greater impact in its first four months of operation than Rolling Thunder had in three and one-half years." Although Henry Kissinger may have announced that peace was at hand, it was not going to come easily. American bombers would once again return to the skies of North Vietnam in 1972 during Operation Linebacker II before the American commitment to the Vietnam War came to an end.
