The AGM-114 Hellfire missile underwent test firings at the Site C-7 Hellfire range on Range 72 from 1980. Upgraded Hellfire tests continue through 2011, with the AGM-114R Hellfire II being successfully tested in August 2010. The first AGM-65E laser Maverick missile was fired at Eglin AFB on 3 June 1980 from a Marine Corps Douglas A-4M Skyhawk. The missile was the laser-guided version of the USAF’s air-to-ground Maverick with a heavier warhead. It was being developed by Hughes Aircraft Company for use by the Marine Corps in close-air support of combat troops. On 25 October 1980, the historic Valparaiso Inn, which served as the Eglin Officers' Club during World War II, was destroyed by fire. It had remained vacant since another blaze severely damaged it on 2 March 1977. In 1981 the original building housing the Air Force Armament Museum was condemned and the facility closed until 1984. The Navy F/A-18 Hornet began climatic testing by the Air Force’s 3246th Test Wing at the McKinley Climatic Laboratory on 23 March 1981. The tests were designed to evaluate the F/A-18 airframe’s ability to withstand the wide range of temperatures and climatic conditions which the aircraft would experience in its everyday operations. The Hughes YAH-64 underwent testing in the McKinley Climatic Laboratory from 2 November to 16 December 1981, consisting of 14.4 hours of operating time. The U.S. Army Aviation Engineering Flight Activity was responsible for the evaluation of aircraft systems and the U.S. Army Aviation Development Test Activity was responsible for the mission equipment evaluation. The U.S. Army formally accepted its first production AH-64A Apache in January 1984. Southeastern Airlines, an Atlanta-based operation, commenced flights into Okaloosa Air Terminal on 15 November 1982. It was acquired by Atlantic Southeast Airlines, a Delta Connection carrier, on 1 April 1983. Two Piper PA-48 Enforcers were tested during 1983 and 1984 at Eglin AFB, and Edwards AFB, California. As in the Pave COIN tests of 1971, the PA-48s were found to perform well in their intended role for counter-insurgency, but the USAF again decided not to purchase the aircraft being apparently uninterested in adding tail-dragger propeller-driven aircraft to the inventory. Construction began in 1984 on the Bob Hope Village, the only retirement facility that caters to enlisted military, opening in February 1985.
