Due to the increasing cost of fuel, the United States Navy and Coast Guard will begin testing a helium filled blimp to patrol the coastal waters off of Florida.

From Reuters:

With oil prices rising sky-high, the U.S. Navy and Coast Guard will test a helium-filled blimp to see if it can supplement the fuel-hungry aircraft that search the Florida Straits for smugglers and boats in distress.

The Navy is leasing a Skyship 600, about the size of a Boeing 747, for the six-week test mission between Florida’s southern coast and Cuba, Coast Guard Lt. Matthew Moorlag said on Tuesday.

The manned ship is held aloft by nonflammable helium and propelled by two Porsche 930 engines that consume 10 to 12 gallons of regular gasoline per hour.
