SAC's air war in Vietnam After
the Secretary of Defense rejected LeMay's November 1964 proposal for a "...strategic air campaign against 94 targets in North Vietnam...", thirty SAC B-52Fs were deployed to
Andersen AFB, Guam on 17 February 1965, representing the first increment of SAC aircraft forward deployed for the
Vietnam War. The following month, in March 1965, the
Strategic Air Command Advanced Echelon (SACADVON) was established as a "...liaison unit for CINCSAC [was] located at MACV Headquarters to assist with the B-52 effort." On 23 May 1965, SAC B-52Fs began unarmed missions for radar mapping "...and later to test bombing with the assistance of ground homing beacons..." SAC began
saturation bombing on 18 June 1965 (8000 tons per month in 1966) and conducted
Operation Arc Light missions from 1965 until the end of hostilities involving U.S. forces in 1973. All B-52F missions in 1965 were against targets in
South Vietnam (RVN) except for the December "...Duck Flight mission [that] hit a suspected
VC supply storage area [for which] part of the target box was in Laos." In April 1966, Vietnam operations began with the B-52D model, a 1956 model designed to use the
AGM-28 Hound Dog cruise missile and the
ADM-20 Quail aerial decoys for low altitude operations and modified in late 1965 by Project Big Belly to increase conventional bomb capacity.
SAC's RBS Squadrons were discontinued when most detachment personnel transferred to Vietnam from 1966 to 1973 for
Combat Skyspot ground-directed bombing operations. The first "
Quick Reaction" bombing was the "Pink Lady" mission on 6 July 1966 using SAC B-52D/Fs to support the U.S. Army's
1st Air Cavalry Division. The 1972
Operation Linebacker II also used Skyspot for Hanoi/Haiphong bombings in North Vietnam which resulted in the loss of 25 SAC aircrew members. By May 1967, SACADVON had moved to
Seventh Air Force headquarters at
Tan Son Nhut Air Base, South Vietnam to schedule and coordinate "...strikes for the 7th AF and MACV." From a level of 161,921 military and 20,215 civilian assigned to SAC in June 1968, SAC lost 13,698 first term airmen from November 1968 to May 1969 in a three phase drawdown known as Project 693 to comply with Public Law 90-364. While conventional bombing, air refueling and strategic air reconnaissance operations in Southeast Asia increasingly occupied SAC's operational commitments, SAC's primary mission of nuclear deterrence continued to remain its primary focus. In 1969, "...SAC's B-52s and B-58s could carry B28, B41, B43, B53, and BA53 nuclear weapons" (SAC had 311 nuclear
AGM-28 Hound Dog missiles at the end of the year.) This also coincided with the
B-58 Hustler's in-progress retirement from SAC's active inventory and its replacement with the
FB-111. On 18 March 1969, along the South Vietnamese border, SAC first bombed Cambodia (
Operation Menu through 26 May 1970 was controlled by Skyspot). On 17 February 1970, SAC conducted the first "GOOD LOOK" bombing of Laos at the
Plaine des Jarres after B-52 photorecon missions ("GOOD LOOK ALPHA" in August 1969 and "GOOD LOOK BRAVO" ) and the observations of a
Skyspot installation in Thailand. SAC transferred "...HQ 8th AF...to
Andersen AFB, Guam on 1 April 1970 to oversee B-52D/G operations and to complement SACADVON". 8th AF took over from
Third Air Division the generation of
"frag" orders based on daily strike requests and amendments from
COMUSMACV. In 1970, SAC deployed the
LGM-30G Minuteman III ICBM with
multiple independently targetable reentry vehicle or MIRVs, for striking 3 targets, while concurrently retiring the
B-58 Hustler supersonic bomber. 1972 saw the commencement of
Operation Linebacker II, a combined
Seventh Air Force and
U.S. Navy Task Force 77 aerial bombing campaign, conducted against targets in North Vietnam during the final period of US involvement in the Vietnam War. Linebacker II was conducted from 18 to 29 December 1972, leading to several informal names such as "The December Raids" and "The Christmas Bombings". Unlike the previous Operation Rolling Thunder and Operation Linebacker interdiction operations, Linebacker II would be a "maximum effort" bombing campaign to destroy major target complexes in the Hanoi and Haiphong areas which could only be accomplished by SAC B-52D/Gs. It saw the largest heavy bomber strikes launched by the U.S. Air Force since the end of World War II. Linebacker II was a modified extension of the Operation Linebacker bombings conducted from May to October 1972, with the emphasis of the new campaign shifted to attacks by B-52 Stratofortress heavy bombers rather than smaller tactical fighter aircraft. During Linebacker II, a total of 741 B-52D/G sorties were dispatched from bases in Thailand and Guam to bomb North Vietnam and 729 actually completed their missions. Overall SAC losses during Linebacker II numbered fifteen B-52s. The U.S. government claimed that the operation had succeeded in forcing North Vietnam's Politburo to return to the negotiating table, with the
Paris Peace Accords signed shortly after the operation. By early 1973, offensive SAC air operations in Southeast Asia ceased and numerous SAC aircrewmen who had been shot down and captured as prisoners of war by North Vietnam were repatriated to the United States. SAC aircraft used during the
Vietnam War included
B-52D, B-52F, B-52G,
KC-135A, KC-135Q, various versions of the
RC-135,
SR-71,
U-2, and
EC-135.
Post-Vietnam, 1970s budget cuts, 1980s renewal, and the Cold War redux During the Vietnam War, due to the escalating costs of combat operations in Southeast Asia, SAC was required to close several SAC bases, consolidate other bases, or transfer several bases to other MAJCOMs, other services, or the Air Reserve Component in order to remain within budgetary constraints. This included: •
Altus AFB (transferred to MAC, later to AETC) •
Bergstrom AFB (transferred to TAC, then ACC until
BRAC closure in 1993) •
Columbus AFB (transferred to ATC, now AETC) •
Clinton-Sherman AFB (closed) •
Dow AFB (closed; portion transferred to ANG as Bangor ANGB) •
Hunter AFB (transferred to US Army as Hunter AAF) •
Larson AFB (closed) •
Lincoln AFB (closed; portion transferred to ANG as Lincoln ANGB) •
Little Rock AFB (transferred to TAC, later MAC, now AMC) •
Mountain Home AFB (transferred to TAC, now ACC) •
Turner AFB (transferred to USN as NAS Albany in 1968, closed 1975) With the Vietnam War draw-down following the Paris Peace Treaty in 1973, reduced defense budgets forced SAC to inactivate several more wings, close still more bases in CONUS and Puerto Rico, transfer still additional bases to other MAJCOMS or the Air Reserve Component, and retire older B-52B, B-52C, B-52E and B-52F aircraft: •
Davis-Monthan AFB (transferred to TAC, now ACC) •
Forbes AFB (closed; portion transferred to ANG as Forbes ANGB) •
Glasgow AFB (closed) •
Kincheloe AFB (closed) •
McCoy AFB (closed; portion transferred to USN as
Naval Training Center Orlando McCoy Annex until its
BRAC-directed closure in 1999) •
Ramey AFB (closed; portion transferred to USCG as CGAS Borinquen) •
Rickenbacker AFB (closed; portion transferred to ANG as Rickenbacker ANGB) •
Westover AFB (transferred to AFRES, now AFRC, as Westover ARB) •
Wright-Patterson AFB (tenant SAC presence departed and transferred to Beale AFB; base remained with AFLC, now AFMC) In 1973, the
National Emergency Airborne Command Post, or NEACP, aircraft entered SAC's inventory. Consisting of four
Boeing E-4 aircraft, these highly modified
Boeing 747 airframes were assigned to the
55th Strategic Reconnaissance Wing at
Offutt AFB and were forward deployed as necessary to support the
National Command Authority. By 1975, SAC's manned bomber strength included several hundred B-52D, B-52G, B-52H and FB-111A aircraft, and "...SAC's first major exercise in 23 years" was Exercise Global Shield 79. As for the ICBM force, SAC reached a peak strength of 1000 Minuteman II and III and 54 Titan II ICBMs on active status before seeing reductions and retirements through a combination of obsolescing systems and various arms reduction treaties with the Soviet Union. By 1977, SAC had been pinning its hopes for a new manned strategic bomber in the form of the
Rockwell B-1A Lancer. However, on 30 June 1977, President
Jimmy Carter Carter announced that the B-1A would be canceled in favor of ICBMs, submarine-launched ballistic missiles (SLBMs), and a fleet of modernized B-52s armed with air-launched cruise missiles (ALCMs). On 1 December 1979, SAC assumed control of the
ballistic missile warning system (BMEWS) and all
Space Surveillance Network facilities from the inactivating
Aerospace Defense Command (ADC). These activities would later be (transferred to
Air Force Space Command (AFSPC) when the latter was established in 1982. SAC also continued to operate the Air Force's entire KC-135 aerial refueling fleet, its EC-135 LOOKING GLASS and E-4 NEACAP command post aircraft, as well the entire strategic reconnaissance aircraft fleet consisting of the U-2, SR-71, RC-135, and WC-135. In 1981, SAC received a new air refueling tanker aircraft to supplement the aging
KC-135 Stratotanker force. Based on the
McDonnell Douglas DC-10 commercial airliner, the
KC-10A Extender was deployed equipped with improved military avionics, aerial refueling, and satellite communications equipment. That same year, President
Ronald Reagan reversed the 1977 Carter administration decision regarding the B-1, directing that 100 examples of a refined version of the aircraft, now designated the B-1B Lancer, be procured as a long-range combat aircraft for SAC. The
LGM-118A Peacekeeper ICBM reached SAC in 1986, and the 114 Peacekeepers had a total warhead yield of about 342 megatons. This also served to offset the retirement of the obsolescent and maintenance-intensive
LGM-25C Titan II ICBM, the last example of which was deactivated in May 1987. An additional underground "16,000 square-foot, two-story reinforced concrete" command post for HQ SAC was also constructed at Offutt AFB from 1986 to 1989 from a design by
Leo A. Daly, who had designed the adjoining 1957 bunker. The first
Rockwell B-1B Lancer was also delivered to SAC in 1987. On 22 November 1988, the
Northrop Grumman B-2 Spirit, under development as the Advanced Technology Bomber (ATB), a so-called
"black program" since 1979, was officially acknowledged and rolled out for the first time for public display. The first "
stealth bomber" designed for SAC, the aircraft made its first flight in May 1989. == End of the Cold War and Operation Desert Storm ==
