The Coast Guard made the first-ever helicopter carrier
Believe it or not, some of the greatest pioneers in the use of military helicopters were Coast Guardsmen. These early breakthroughs took place during World War II when the Navy was too busy expanding traditional carrier operations to focus on rotary wing, and the Army had largely sequestered helicopters to an air commando group. The Coast Guard, meanwhile, was working on what would be the first-ever helicopter carrier.

Obviously, we're talking about a ship that carries helicopters, not an aircraft carrier that flies like a helicopter. The Avengers aren't real (yet).
The potential advantages of helicopters in military operations were clear to many of the military leaders who witnessed demonstrations in the early 1940s. Igor Sikorsky had made the first practical helicopter flight in 1939, and the value of an aircraft that could hover over an enemy submarine or take off and land in windy or stormy weather was obvious.
