330-PS-583 (USN 707917):   Latest photograph of U.S. Navy’s new N-Type, non-rigid airship nearing completion in Goodyear Aircraft Corporation Hangar at Akron, Ohio.  The net shrouding the huge ship is used to hold the helium-filled envelope down while the control car and other fixtures are being attached. – Main caption:  As one answer to the threat of enemy submarines, a new type blimp has been developed.  The largest non-rigid airship ever built, the N-type is capable of carrying more submarine detection devices, and also flying longer and farther without refueling.  Airships, operating with planes and surface ships, have proved very successful in seeking out and tracking submarines.  The ability of the blimp is to fly safely at low-altitudes and at slow speeds, coupled with its capability of staying aloft for extended periods of time without refueling, make it an effective component of a hunter-killer team.  Photograph released August 31, 1950.  (7/14/2015).
