1924  Congress appropriated $13,000,000 for ten air stations and equipment.  Congress first authorized the stations on August 29, 1916, but did not provide for sufficient funding until this date. The first Coast Guard Air Station had been established in 1920 in Morehead City, NC.

The Morehead City air station remained in commission until July, 1922 at which time personnel were transferred to other assignments and the aircraft were returned to the Navy. There would be no more Coast Guard aviation activity until the advent of the Coast Guard Air Station at Gloucester Massachusetts in 1926. Only five out eleven of the initial cadre returned to flight status.

1982  The first of a new type of aircraft was added to the Coast Guard’s air fleet, a HU-25A Guardian, was dedicated and christened at Aviation Training Center Mobile.

In response to the Iraqi action of firing oil wells and pumping stations in Kuwait, two HU-25A Falcon jets from Air Station Cape Cod, equipped with Aireye technology, which precisely locates and records oil as it floats on water], departed for Saudi Arabia. The Falcons mapped over 40,000 square miles in theatre and located every drop of oil on the water. This was used to produce a daily updated surface analysis of the location, condition and drift projections of the oil. The Aviation Detachment was deployed for 84 days, flew 427 flight hours and maintained an aircraft readiness rate of over 96 percent.

1983  The State Department forwarded a request for assistance from the United Arab Emirates to help prepare for an oil spill cleanup in the Persian Gulf.  The spill occurred after combat operations during the Iran-Iraq war had left many oil wells burning and leaking oil.  Four Coast Guard pollution experts responded to the request.
