The 1st Combat Evaluation Group (initially "1CEG", later "1CEVG") was a Strategic Air Command (SAC) unit. It was formed on 1 August 1961 to merge the 3908th Strategic Standardization Group for SAC aircrew evaluation with the 1st Radar Bomb Scoring Group that had originated from the 263rd Army Air Force Base Unit which transferred from 15th AF to directly under Strategic Air Command c. 1946. [1] The 1CEVG formed after SAC switched to low-level tactics to counter Soviet surface-to-air missiles ("Oil Burner" training routes in 1959) [2] [3] and SAC had "developed a Radar Bomb Scoring field kit for use in NIKE Systems" in early 1960 for scoring SAC training missions against US Hercules SAM sites. [4] The 1CEVG headquarters included an Office of History [1] and a "standardization and evaluation school" for command examiners. [5]
The 1CEVG deputy commander for standardization and evaluation was responsible for performance assessment of SAC tanker and bomber flight crews. [6] 1CEVG also evaluated the RC-135 units at Eielson, Kadena, and Offutt, the flight crew standardization of the U-2, the DC-130 reconnaissance drone program, CH-3 helicopter drone recovery program, [and] the SR-71 program at Beale AFB. [7]
The Fairchild Trophy was Strategic Air Command's top Bombardment Award, for which the Group administered flight checks and evaluated standardization and training activities. [8]
1CEVG included a Command Instrument Flight Division [9] and an RBS Division with 3 squadrons.
The Radar Bomb Scoring Division controlled the group's Radar Bomb Scoring units. As with the preceding 1st Radar Bomb Scoring Group at Carswell AFB, the division had 3 Radar Bomb Scoring Squadrons (10th, 11th, 12th) with RBS detachments at fixed radar stations and at semi-mobile radar stations (Mobile Duty Locations (MDLs)). The MDLs were set up for SAC special missions, with their equipment, trailers, books, etc., stored at Barksdale AFB when not in use. Each squadron manned an RBS Express train, but the squadrons were inactivated in 1966 after Vietnam War deployments had begun. The three squadrons in 1959 had 29 AUTOTRACK sites. [10] 1CEVG temporary duty personnel at Nike Defense Areas also scored mock SAC raids tracked by the Army.
RBS trains were inactivated later in the war after the 1968-9 Project 693 discharging 1st term SAC airmen up to 11 months early. The division included a maintenance office. [11] After the Vietnam War ended, the annual Combat Skyspot trophy was awarded for the outstanding RBS detachment (e.g., Louis Blotner Radar Bomb Scoring Site (Ashland Det 7) in 1985). [12]
The squadrons initially used Matador Automatic Radar Control (AN/MSQ-1) and AN/MSQ-2 automatic tracking radar/computer systems. The Reeves AN/MSQ-35 Bomb Scoring Central was developed for the division (mid-1963 testing was at the White Sands Missile Range.) [13] During the Vietnam War, the Statesboro Bomb Scoring Site used a Soviet T2A for training crews to jam the signal. Three US bombing systems developed during the war (AN/MSQ-77, AN/TSQ-81, & AN/TSQ-96) were used post-war in the United States by the RBS Division, which replaced them with the c. 1980 solid-state US Dynamics AN/TPQ-43 Bomb Scoring Set (SEEK SCORE) developed from the AN/TPB-1C Course Directing Central. [14]
The Electronic Systems Division 806L "Range Threat" systems for electronic warfare simulation were developed for use by 1CEVG late in the Cold War. [15] Such systems included the US Dynamics AN/MST-T1 Miniature-Multiple Threat Emitter Simulator (MUTES), for which the group evaluated the prototype in 1977 (operational in October 1978). Similarly, TLQ-11 jammer improvements were in 1978, and in 1979 1CEVG members completed a prototype study and testing of the new Threat Reaction Analysis Indicator System (TRAINS) for analyzing how aircrews and avionics reacted to ground-based threats.
At the end of the Cold War, most RBS detachments were closed. [16] The personnel and the assets of the RBS Division became the 1st Electronic Combat Range Group on 1 July 1989 when the 1CEVG was split, and other 1CEVG organizations transferred to SAC headquarters.

Detachment 7, 1 CEVG was a Matagorda Island Air Force Base [36] [ verification needed ] radar site for the "Busy Skyspot" training program for automatic tracking radar crews to use the Reeves AN/MSQ-77 Bomb Directing Central before transferring to Vietnam War operating locations. A CONUS AN/MSQ-77 had initially been used at the mountainous Nellis Air Force Range before being moved to the Gulf Coast of the United States, then the detachment moved to Bergstrom Air Force Base and was redesignated Det 50 for long range tracking of bombers [36] on 2 Matagorda Island Air Force Range routes (low- and high-level). [37] On 29 February 1968, on the low-level Matagorda route a Boeing B-52 Stratofortress crashed into the Gulf of Mexico. [37]
Detachment 15, 1CEVG at the Vietnam War's Tan Son Nhut Air Base served as an "administrative link between [the operating locations] and Headquarters 1st Combat Evaluation Group" [38] after Reeves AN/MSQ-77 Bomb Directing Centrals were produced and deployed in 1965 for Combat Skyspot bomber operations by tactical fighter, B-52, and other units. On 5 June 1966 near Đông Hà Combat Base close to the DMZ, six 1CEVG technicians were killed while conducting a preliminary site location survey. [39]
Strategic Air Command (SAC) was a United States Department of Defense Specified Command and a United States Air Force (USAF) Major Command responsible for command and control of the strategic bomber and intercontinental ballistic missile components of the United States military's strategic nuclear forces from 1946 to 1992. SAC was also responsible for strategic reconnaissance aircraft; airborne command posts; and most of the USAF's aerial refueling aircraft.
During Operation Arc Light from 1965 to 1973, the United States Air Force deployed B-52 Stratofortresses from bases in the U.S. Territory of Guam to provide battlefield air interdiction during the Vietnam War. This included strikes at enemy bases, supply routes, and behind the lines troop concentrations, as well as occasionally providing close air support directly to ground combat operations in Vietnam.
Rome Laboratory is the US "Air Force 'superlab' for command, control, and communications" research and development and is responsible for planning and executing the USAF science and technology program.
Ground-directed bombing (GDB) is a military tactic for airstrikes by ground-attack aircraft, strategic bombers, and other equipped air vehicles under command guidance from aviation ground support equipment and/or ground personnel. Often used in poor weather and at night, the tactic was superseded by an airborne computer predicting unguided bomb impact from data provided by precision avionics Equipment for radar GDB generally included a combination ground radar/computer/communication system and aircraft avionics for processing radioed commands.
The Reeves AN/MSQ-77 Bomb Directing Central, Radar was a United States Air Force automatic tracking radar/computer system for command guidance of aircraft. It was often used during Vietnam War bomb runs at nighttime and during bad weather. Developed from the Reeves AN/MSQ-35, the AN/MSQ-77 reversed the process of Radar Bomb Scoring by continually estimating the bomb impact point before bomb release with a vacuum tube ballistic computer. Unlike "Course Directing Centrals" which guided aircraft to a predetermined release point, the AN/MSQ-77 algorithm continuously predicted bomb impact points during the radar track while the AN/MSQ-77's control commands adjusted the aircraft course. A close air support regulation prohibited AN/MSQ-77 Combat Skyspot bombing within 1,000 yd (910 m) of friendly forces unless authorized by a Forward Air Controller, and "on several occasions" strikes were as close as 273 yd (250 m).
Radar Bomb Scoring is a combat aviation ground support operation used to evaluate Cold War aircrews' effectiveness with simulated unguided bomb drops near radar stations of the United States Navy, the USAF Strategic Air Command, and Army Project Nike units. USAF RBS used various ground radar, computers, and other electronic equipment such as jammers to disrupt operations of the bomber's radar navigator, AAA/SAM simulators to require countermeasures from the bomber, and Radar Bomb Scoring Centrals for estimating accuracy of simulated bombings. Scores for accuracy and electronic warfare effectiveness were transmitted from radar sites such as those at Strategic Range Training Complexes.
RBS Express railroad trains were 3 mobile United States Air Force radar stations for 1CEVG Radar Bomb Scoring (RBS) of Strategic Air Command bomber crews beginning in March 1961. Electronic equipment included the "MSQ-39, TLQ-11, MPS-9, and the IFF/SIF for the MSQ-39" along with support railcars, and the trains were temporarily used at various rail sites with the radar antennas emplaced using hoists built onto flatcars. Pulled by a "contracted locomotive" that left the train at the site, and a North American B-25 Mitchell was used for calibration of the radar station.
The Reeves AN/MSQ-35 Bomb Scoring Central was a United States Air Force dual radar system with computerized plotting board. It was used by the 1st Combat Evaluation Group to evaluate the accuracy of Strategic Air Command bomber crews.
Lima Site 85 was a clandestine military installation in the Royal Kingdom of Laos guarded by the Hmong "Secret Army", the Central Intelligence Agency, and the United States Air Force used for Vietnam War covert operations against communist targets in ostensibly neutral Laos under attack by the Vietnam People's Army. Initially created for a CIA command post to support a local stronghold, the site was expanded with a 1966 TACAN area excavated on the mountaintop where a 1967 command guidance radar was added for Commando Club bombing of northern areas of North Vietnam. The site ended operations with the Battle of Lima Site 85 when most of the U.S. technicians on the mountaintop were killed, including CMSgt Richard Etchberger. For his heroism and sacrifice, Etchberger received the Air Force Cross posthumously. The operation remained classified, however, and the existence of the award was not publicly acknowledged until 1998. After the declassification of LS 85 and a reevaluation of his actions, Etchberger was awarded the Medal of Honor in 2010.
Combat Skyspot was the ground-directed bombing (GDB) operation of the Vietnam War by the United States Air Force using Bomb Directing Centrals and by the United States Marine Corps using Course Directing Centrals. Combat Skyspot's command guidance of B-52s and tactical fighters and bombers—"chiefly flown by F-100's"—at night and poor weather was used for aerial bombing of strategic, close air support, interdiction, and other targets. Using a combination radar/computer/communications system at operating location in Southeast Asia, a typical bombing mission had an air command post turn over control of the mission to the radar station, and the station provided bomb run corrections and designated when to release bombs.
The AN/MPQ-2 Close Cooperation Control Unit was a truck-mounted pautomatic tracking radar/computer/communication system for aircraft command guidance, e.g., missile tracking, and for Radar Bomb Scoring. It was introduced shortly after the end of World War II. For ground directed bombing (GDB), an operator would manually plot a target on the "Blind Bombing Plotting Sheet", then use the manual "E6B computer and bombing tables" to plot the release point for striking the target, after which a radar operator used the AN/MPQ-2 to acquire a track of the bomber near an initial point during which allowed ground control of the bomb run to the release point.
The 99th Range Group is an inactive United States Air Force (USAF) unit. It was last stationed at Nellis AFB, Nevada, where it was responsible for the Nevada Test and Training Range (NTTR).
Matador Automatic Radar Control (MARC) was a command guidance system for the Martin MGM-1 Matador ground launched cruise missile that used combination radar/computer/communication centrals for ground-directed bombing. As for the earlier ground central used with the X-10 aircraft,* MARC had an "Air Link" from the ground for control and an airborne AN/APW-11A radar transponder on the missile for ranging. A series of "MSQ sites". each with a mobile AN/MSQ-1A central in 3 vans had an automatic tracking radar to geolocate the Matador up to ~600 nmi. MARC provided command guidance during the "mid-course phase" after Matador/MARC contact was established following the missile launch off the Zero Length Launcher and until an MSQ transmitted the dive ("dump") command to start the flight path toward the target. Originating in the Caltech/Martin "ZEL Project" and developed as part of weapon system "Project MX 771" at the "Air Force Missile Test Center, Cocoa, Florida"; MARC had accuracy at "crossover into enemy territory" of ~500 ft (150 m) and—at an AN/MSQ-1A range of 165 nautical miles —a CEP of 2,700 ft (820 m).
Hawthorne Bomb Plot is a Formerly Used Defense Site that had a Strategic Air Command (SAC) AUTOTRACK radar station during the Cold War. Operations began at a temporary RBS train site for RBS Express #2 was at the Hawthorne area in December 1961, and the 11th Radar Bomb Scoring Squadron subsequently established the fixed military installation for Radar Bomb Scoring in Babbitt, Nevada, the military housing community near the local Navy/Army depot.
The Interior Radar Bomb Scoring Site opened in August 1960 on Hurley Butte, adjacent to the Pine Ridge Indian Reservation and a few miles from Interior, South Dakota. The Interior RBSS is a Formerly Used Defense Site, that closed in 1968.
The 3903rd Radar Bomb Scoring Group was a military evaluation unit under direct command of Strategic Air Command (SAC) headquarters for scoring simulated bomb runs using automatic tracking radar stations. Initially an Army Air Forces Base Unit (AAFBU) and then a squadron, the 3903rd RBS Group was personnel, assets, and detachments were redesignated the 1st Radar Bomb Scoring Group and then the 1CEVG Radar Bomb Scoring Division when the RBS Group merged with the 3908th Strategic Standardization Group in 1961, the year RBS Express trains began to be used for low-altitude Boeing B-52 Stratofortress operations..
The Louis Blotner Radar Site was a tracking site site in Connor, Maine at the former NIKE missile launch site. Activated in June 1963 and operational until after 1979, The Ashland site was an AUTOTRACK radar site operated by Detachment 7 of the 1st Combat Evaluation Group. The station simulated Electronic Countermeasures and Radar Bomb Scoring for the Ashland Training Range's low-level training route "over Bangor north to Houlton, Maine.
The Reeves AN/MSQ-1 Close Support Control Set produced by Reeves Instrument Corporation was a trailer-mounted combination radar/computer/communication developed under a Rome Air Development Center program office for Cold War command guidance of manned aircraft Developed for Korean War ground-directed bombing, one detachment of the 3903rd Radar Bomb Scoring Squadron bombed itself with an MSQ-1 because it mistakenly used procedures for the earlier SCR-584/OA-294 system The MSQ-1 was subsequently used for nuclear testing during Operation Teapot, and for aircraft tests such as for "MSQ-1 controlled pinpoint photography" in 1954.
Havre Electronic Bomb Scoring Site is a Formerly Used Defense Site for USAF evaluation of aircrews on training missions. The site was initially established for the 1965 Fairchild Trophy, the Strategic Air Command Bombing and Navigation Competition. ; the RBS Express was stationed at a siding near Chinook, Montana; and a new "temporary mobile radar site" 35 mi (56 km) northeast of Havre, Montana, was announced in 1982. The 1983 site was in Hill County, Montana, with seven semi-trailers, and a new permanent site was approved by 1984 for also north of Havre "Upon decommissioning of [the mobile site at] Havre, MT Serial Number 7 went to Detachment 18, Forsyth, Montana for SAC Bomb-Comp 1987 and then to Detachment 20, 1 CEVG in early 1988."
Ashland Radar Station was a United States Air Force station located in Ashland, Maine operational from around 1975 to 1990. Sitting on 6.59 acres (2.67 ha).
SAC had 64 detachments at the end of FY-69, an increase of nine, offset by a reduction of three. One discontinued was Detachment 4, 1st Combat Evaluation Group (CEG), Oronogo, Missouri.
