The AAFAC flew antisubmarine patrols, searching for and attacking German U-boats from the airport using B-18 Bolo and B-24 Liberator bombers specially equipped with radar.

Beginning in June 1941, the Miami 36th Street Airport had been established as a lend-lease supply line to British forces fighting in the Near East.

Ferrying of aircraft from the airport started as early as June of that year, when a Pan American Airways subsidiary (Pan American Air Ferries, Inc) (PAAF) undertook the delivery of twenty lend-lease transport planes to Lagos on the Nigerian coast of western Africa, where the British had developed a trans-African air route to Khartoum in the Anglo-Egyptian Sudan.

The success of this first operation led to contracts between the War Department and Pan American organization for more permanent ferrying and transport services all the way into Khartoum.

Homestead Field was assigned to the ATC Caribbean Wing in order to insure adequate staging facilities for the heavy flow of ferried aircraft were available after the invasion of North Africa.

In May 1944, Pan American Airways began flying the middle Atlantic route, going from Miami Airport through Bermuda and the Azores to Casablanca, French Morocco.

As a result, by 10 August Green Project goals had been cut from transporting 50,000 to 35,000 personnel a month from overseas combat theaters to Florida.

Two years earlier, Continental Air Command had assigned the Reserve 100th Bombardment Group to the airport with two squadrons of B-29 Superfortresses.

Although reactivated the same day, the administrative unit was not returned to strength until July 1953 when the 456th Troop Carrier Wing transferred its personnel and equipment to the 435th.

The increasing growth of the Miami Airport and the large volume of aircraft traffic led the Air Force to inactivate the Troop Carrier units in 1959.
