Previously called the Wilmington Airport and the Greater Wilmington Airport, the property
became a Army Air Forces military airfield named New Castle Army Air Base (AAB) during
World War II.

Opened in May 1943,] New Castle AAB was assigned to the Air Corps Ferrying Command 2d
Ferrying Group with the 552d Army Air Forces Base Unit being the host unit in charge of the
base and its facilities. The primary mission of the airfield was to facilitate the movement of
aircraft overseas for delivery to the British and other Allies. Members of the historic Women Air
Force Service Pilots(WASP). WASPs served as test and ferry pilots and towed targets for student
gunners. There is a statue today at the airport that honors the women of WASP that served
their country in the time of need. On 30 June 1945, the 1596th AAF Base Unit replaced the 552d
AAFBU and the 2d Ferrying group was replaced by the 2d Foreign Transport Group. The
mission of the base was changed to being responsible for overseas air transport of passengers
and air cargo.] With the general drawdown of the Air Force after the war, New Castle Airport
became a joint-use base, with civilian aircraft operating from the airfield as an airport.

On 1 September 1949, the military facilities at the airport were assigned to Continental Air
Command (ConAC) and theAir Force Reserve 512th Air Base Group became the host unit,
remaining so until 31 January 1951 when it was reassigned to Reading Municipal Airport,
Pennsylvania,. In 1950 the facility was renamed "New Castle Air Force Base" and on 8 September
1950, the
4th Fighter-Interceptor Wing, equipped with the F-86A Sabre was reassigned to New
Castle, giving the airfield an air-superiority mission. The 4th FIW was deployed to Japan on 10
November 1950, with a mission to counter the MiG threat in the skies of Korea. The 4th FIW
became the top MiG killing organization during the Korean War. In addition to the 4th FIW,
the 334th Fighter-Interceptor Squadron was activated on the base in 1950, initially flying F-80
Shooting Stars, and in 1952, being replaced by F-94 Starfires. In 1952, the 334th was involved in
a UFO incident when its interceptors were scrambled to intercept unknown objects detected
flying over Washington, D.C.

The 512th ABG was replaced by the Federalized Delaware Air National Guard's 113th Air Base
Group becoming the host unit on 1 February 1951. The mission of the 113th was to organize,
administer, equip, train and prepare assigned personnel for combat and to maintain a level of
operational effectiveness. During its tenure as host unit, the Air Force Reserve and the 512th
Troop Carrier Group flying C-46 Commandoes (325th, 326th, 327th and 328th Troop Carrier
Squadrons) returned from Reading after it closed as a reserve facility. The 512th remained at
New Castle as a reserve tenant unit until being reassigned to Willow Grove Air Reserve Station,
Pennsylvania on 20 July 1958.

With its activation ended in 1952, the 113th was replaced by the 82d Air Base squadron on 2
January 1952.

New Castle Airport was reassigned to Air Defense Command (ADC) on 16 February 1953, and
the 4710th Defense (later Air Defense) Wing became the host unit. (16 February 1953-1 March
1956). With its activation, the base was assigned to the Eastern Air Defense Force 26th Air
Division In addition, plans were made to elevate the base to a full USAF installation. In March
1953, the F-94C Starfire 332nd Fighter-Interceptor Squadron joined the 334th FIS at New Castle.

In 1955, the ADC units at New Castle were upgraded to a group level, with the activation of the
82nd Fighter-Interceptor Group. The squadrons were re-designated as the 97th and 96th
Fighter-Interceptor squadrons, still fling F-94Cs.

In 1957, it was announced that Air Defense Command would be reducing its forces, and the 82d
FIG was inactivated on 8 January 1958. The base was downgraded to an Air National Guard
facility, with the facility being turned over to local authorities. The New Castle County Airport
then hosted the 166th Air Transport Group, successively known as the 166th Military Airlift
Group, 166th Tactical Airlift Group, 166th Airlift Group and now known as the 166th Airlift
Wing, operating C-130H Hercules.

In the mid-1990s, the Base appeared on the federal Base Realignment and Closure list in a
context which would have grounded the 166th Airlift Wing. Further, the Base was among
those targeted for closure by the Pentagon as of May 2005. However, by the late 1990s a reversal
in the fate of the Base had been realized and in excess of $130 million in federal funds had been
allocated for capital projects for Base improvement.
