U.S. Navy of the utility of the helicopter and eventually enlisted the aid of Executive Officer Lieutenant Commander Frank Erickson of Coast Guard Air Station Brooklyn.

Acquisition and refit
As part of its ASW program, the Coast Guard began experimenting with ship-based helicopter operations. Initially, a series of flights was conducted from the deck of a ship at anchor, ''Bunker Hill''. When these trials proved successful, the Coast Guard moved to open sea trials.
For the sea trials, the Coast Guard acquired an ageing passenger steamer, , from the War Shipping Administration

. The Coast Guard carried out major modifications to the ship, including removal of much of the ship's superstructure for the installation of a 38 × 63 foot flight deck for the use of helicopters, plus the addition of armor and weaponry. Following these modifications, the ship was commissioned on 20 July 1943 as USCGC ''Cobb'' (WPG-181)—the first US helicopter carrier.[

s greatly diminished by early 1945, the Coast Guard turned its attention to development of the helicopter in the search-and-rescue role. USCGC ''Cobb'' also played a role in this program when helicopters from its flight deck performed some of the earliest air-sea rescues.[
In spite of her historic achievements, USCGC ''Cobb'' proved an unsatisfactory acquisition. Originally America's first turbine-powered steamship, the aging 37-year-old vessel proved a liability to the Coast Guard with her excessive maintenance costs. During the first 115 days of the ship's service, ''Cobb'' was absent from the repair yard for a total of only nine days. Thereafter she managed operational duties an average of only one week out of four.][
USCGC ''Cobb'' was decommissioned by the Coast Guard on 31 January 1946. She was sold on 6 March 1947,][ and scrapped a short time later.
