Question: What s a United States Air Force installation with more squadrons than any other USAF base, that ran wo back-to-back Joint Test & Evaluations chartered by the United States Department of Defense that ran from 1974-78?
Context: Hurlburt Field (ICAO: KHRT, FAA LID: HRT) is a United States Air Force installation located in Okaloosa County, Florida, immediately west of the Town of Mary Esther.  It is part of the greater Eglin Air Force Base reservation, and is home to Headquarters Air Force Special Operations Command (AFSOC), the 1st Special Operations Wing (1 SOW), the USAF Special Operations School (USAFSOS) and the Air Combat Command's (ACC) 505th Command and Control Wing.  It was named for First Lieutenant Donald Wilson Hurlburt, who died in a crash at Eglin.  The installation is nearly 6700 acre , and employs nearly 8,000 military personnel. The Vice Chief of the National Guard Bureau (VCNGB) is the second highest-ranking officer of the National Guard Bureau, which is a joint activity of the United States Department of Defense.  The Vice Chief of the National Guard Bureau is the second in charge of the National Guard of the United States; which is a joint reserve component of the United States Army and the United States Air Force.  The VCNGB serves as the principal advisor to the Chief of the National Guard Bureau and the Secretary of Defense, through the Chairman of the Joint Chiefs of Staff, on matters involving non-federalized National Guard forces and on other matters as determined by the United States Secretary of Defense.  The VCNGB also serves as the principal adviser to the Secretary of the Army, Secretary of the Air Force, the Chief of Staff of the Army, and the Chief of Staff of the Air Force, on matters relating to federalized forces of the National Guard of the United States and its subcomponents; the Army National Guard of the United States, and the Air National Guard of the United States. The 4700th Air Defense Group is a discontinued United States Air Force (USAF) organization.  Its last assignment was with the 4709th Air Defense Wing at Stewart Air Force Base, New York.  It was activated in 1950 as a support unit for USAF units at Stewart.  In 1954, it assumed an operational mission and was assigned two interceptor squadrons.  The group was discontinued on 18 August 1955 and its personnel and equipment were transferred to the 329th Fighter Group (Air Defense) as part of Project Arrow, an Air Defense Command project to air defense groups with fighter units with distinguished histories from World War I or World War II. The Air Combat Evaluation (ACEVAL) and the Air Intercept Missile Evaluation (AIMVAL) were two back-to-back Joint Test & Evaluations chartered by the United States Department of Defense that ran from 1974-78 at Nellis Air Force Base in Nevada.  Both the U. S. Air Force and Navy participated, contributing a team of F-15 Eagle and F-14 Tomcat fighter aircraft and using the local F-5E Aggressor aircraft as the Red Force.  The fundamental question that needed to be answered was one of "quantity vs quality".  Mock engagements showed that cheaper, lower-technology fighters armed with all-aspect missiles were able to destroy the more advanced, expensive F-15's and F-14's.  These results of the AIMVAL/ACEVAL testing led to the Air Force decision to structure its fighter forces with a balance of cheaper F-16's along with the more expensive F-15's, and the Navy took a similar strategy in procuring cheaper F-18's along with the more expensive F-14's.  The results had other impacts as well, such as decisions regarding missile development. Patrick Air Force Base (IATA: COF, ICAO: KCOF, FAA LID: COF) is a United States Air Force installation located between Satellite Beach and Cocoa Beach, in Brevard County, Florida, in the United States.  It was named in honor of Major General Mason Patrick, USAAC.  An Air Force Space Command (AFSPC) base, it is home to the 45th Space Wing (45 SW).  In addition to its "host wing" responsibilities at Patrick AFB, the 45 SW controls and operates Cape Canaveral Air Force Station (CCAFS) and the Eastern Range.  It was originally opened and operated from 1940 to 1947 as Naval Air Station Banana River, a U.S. Navy airfield.  It was then deactivated as a naval installation in 1947 and placed in caretaker status until it was transferred to the Air Force in late 1948. The 4706th Air Defense Wing is a discontinued United States Air Force (USAF) organization.  Its last assignment was with the 37th Air Division of Air Defense Command (ADC) at O'Hare International Airport (IAP), Illinois where it was discontinued in 1956.  It was established in 1952 at O'Hare as the 4706th Defense Wing in a general reorganization of Air Defense Command (ADC), which replaced wings responsible for a base with wings responsible for a geographical area.  It assumed control of several Fighter Interceptor squadrons that had been assigned to the 142d Fighter-Interceptor Wing, an Air National Guard wing mobilized for the Korean War and the 56th Fighter-Interceptor Group.  In early 1953 it also was assigned six radar squadrons in the Midwest and its dispersed fighter squadrons combined with colocated air base squadrons into air defense groups.  The wing was redesignated as an air defense wing in 1954.  It was discontinued in 1956 and most of its units transferred to the 58th Air Division. Nellis Air Force Base ("Nellis" colloq. ) is a United States Air Force installation in southern Nevada with military schools and more squadrons than any other USAF base.  Nellis hosts air combat exercises such as Exercise Red Flag and close air support exercises such as Green Flag-West flown in "Military Operations Area (MOA) airspace".  associated with the nearby Nevada Test and Training Range (NTTR).  The base also has the Combined Air and Space Operations Center-Nellis. The 4676th Air Defense Group is a discontinued United States Air Force (USAF) organization.  Its last assignment was with the 33d Air Division of Air Defense Command (ADC) at Grandview Air Force Base, Missouri, where it was discontinued in 1955.  The group was activated at Fairfax Field in 1953 as USAF host for both Fairfax and Grandview.  It moved to Grandview when that base was completed and added an operational air defense mission in 1954.  It was discontinued in 1955 when ADC replaced air defense groups commanding fighter squadrons with fighter groups that had distinguished records in the two World Wars. This is a list of United States Air Force squadrons.  It covers both the independent United States Air Force (USAF) and its period as a branch of the US Army culminating as the Army Air Forces up to 1947.  All numbered USAF squadrons are assigned numbers from 1 to 999, with the block 101 to 300 being reserved for the Air National Guard.  Generally speaking the numbers in the 900 block are post World War II units, they may however be consolidated units with lineage and heraldry dating back to World War II or even early as part of the Air Service.  The only official source of lineage information is provided by the Air Force Historical Research Agency at Maxwell Air Force Base, Alabama.  The only official sources of heraldry information are the AFHRA and the Institute of Heraldry, Fort Belvoir, Virginia. The Holloman High Speed Test Track (HHSTT) is a United States Department of Defense/Air Force aerospace ground test facility located at Holloman Air Force Base in south-central New Mexico.  It is adjacent to the White Sands Missile Range and is operated by the 846th Test Squadron of the 96th Test Group of the 96th Test Wing at Eglin Air Force Base.  The Test Track provides its services to a wide variety of American defense and governmental agencies such as the Air Force, Army, Navy, and the Missile Defense Agency, as well as America's allies.
