Interior Radar Bomb Scoring Site

Last updated

The Interior Radar Bomb Scoring Site (callsign Badlands Bomb Plot) opened in August 1960 [1] on Hurley Butte ( 43°43′11″N102°08′35″W / 43.719846°N 102.14294°W / 43.719846; -102.14294 ), adjacent to the Pine Ridge Indian Reservation and a few miles from Interior, South Dakota. [2] The Interior RBSS is a Formerly Used Defense Site, that closed in 1968.

History

It replaced the Los Angeles Bomb Plot at Cheli AFS. Operated and maintained by Detachment 2 of the 11th Radar Bomb Scoring Squadron, Radar Bomb Scoring Division, 1st Combat Evaluation Group (initially by temporary duty personnel), the RBS site was 1 of ~14 that remained after the 1965-6 deployment of RBS site personnel for Vietnam Combat Skyspot.

Family housing for the detachment was on the western edge of Wall, South Dakota, and barracks initially used for the station were shared by Boeing facility contractors for the Ellsworth Air Force Base 850th Strategic Missile Squadron's HGM-25A Titan I ICBMs.

At the end of the Cold War, numerous nearby radar sites for RBS and electronic warfare simulation included those at the Alzada (2 sites), Ekalaka, & Hulett Mini-Mutes Radar Sites, the Clark & Colony Radar Bomb Scoring Sites, and the "Ellsworth Air Force Base" sites (Belle Fourche, Colmer, & Horman Radar Bomb Scoring Sites and the Antelope Butte Mini Mute Radar Bomb Scoring Site). [3]

The Interior Family Housing Site, a "detached installation" of Barksdale Air Force Base provided homes from 26 June 1968 to 30 April 1969. [4] Det 2 moved to the Holbrook Bomb Plot in Arizona in 1968. [5] Concrete pads at Hurley Butte remain from when the RBS equipment and personnel transferred to Holbrook, Arizona (1968-1993) merged w/ Det 19 Poplar MT [2] to move to Det 4 Harrison AR). [6]

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 Often used in poor weather and at night, the tactic was superseded by an airborne computer predicting unguided bomb impact from data provided by precision avionics Equipment for radar GDB generally included a combination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 1st Combat Evaluation Group 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. The 1CEVG formed after SAC switched to low-level tactics to counter Soviet surface-to-air missiles 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. The 1CEVG headquarters included an Office of History and a "standardization and evaluation school" for command examiners.

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).

Cheli Air Force Station, formerly located within Bell in southeastern Los Angeles County, California, was a United States Air Force installation and a Cold War Radar Bomb Scoring site of the Strategic Air Command, from 1947 to 1961.

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.

The Badlands Bombing Range (BBR) refers to Rapid City Army Air Base target ranges for World War II which included the current Air Force Retained Area, an inactive 2,486-acre (10.06 km2) United States Air Force site "20 miles southeast" of Scenic, South Dakota. The retained area is the remainder of 341,726 acres (1,382.92 km2) federally acquired in 1942 under eminent domain at the Pine Ridge Indian Reservation. In addition to use by World War II aircraft, BBR was used for a post-war Army National Guard gunnery range and a Cold War Radar Bomb Scoring site.

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.
