- N-class_blimp abstract "The N-Class, or as popularly known, the Nan ship, was a line of non-rigid airships built by the Goodyear Aircraft Company of Akron, Ohio for the US Navy. This line of airships was developed through many versions and assigned various designators as the airship designation system changed in the post World War II era. These versions included airships configured for both anti-submarine warfare and airborne early warning (AEW) missions. The initial version, designated ZPN-1, was a follow-on to the M-class blimp for patrol missions. The Nan ship used a significantly larger envelope than the M-ship although their overall lengths were similar. Two Wright radial air-cooled engines powered the N-Class blimps.An initial contract was awarded to the Goodyear Aircraft Company for the prototype N-class blimp in the late 1940s, with delivery of the first on in 1952. The ZPN-1 designation was changed to ZPG-1 in 1954, and then to SZ-1A in 1962. The envelope capacity for the ZPN-1 was 875,000 cu ft (24,777 m3) and used the gas helium for lift.The ZPN-1 was followed by an order for four improved N-class blimps that were delivered in 1954. These airships were designated ZP2N, and re-designated in 1954 as the ZPG-2. Three of the ZP2N airships were modified for an airborne early warning mission in the mid-1950s and were designated, originally, ZP2N-1W but at delivery were designated ZPG-2W. Their designation was changed to EZ-1B in 1962. The envelope capacity of these airships exceeded 1×10^6 cu ft (28,317 m3). The ZPG-2W was equipped with the AN/APS-20 radar with its antenna installed beneath the gondola. An AN/APS-69 height-finding radar antenna was mounted on top of the envelope. The engines were installed in the control car and drove the propellers through extended shafts. The airship carried a crew of 21 to 25 and had an endurance capability of over 200 hours. The first ZPG-2W was delivered to the Navy at NAS Lakehurst in May 1955.Operationally the ZPG-2W was used to fill radar gaps in the North American early-warning network between the Contiguous Barrier and the Inshore Barrier during the Cold War. In a demonstration of the ability to stay on-station autonomously for considerably extended periods, ZPG-2 "Snow Bird" (BuNo 141561), pilot in command Cdr. Jack R. Hunt USN, supported by a naval crew of 12 plus a civilian flight engineer from Goodyear, made a record-breaking non-stop flight across the Atlantic and back. The airship departed Naval Air Station South Weymouth, Massachusetts, on Monday 4th March 1957, reaching the south-west tip of Portugal by the evening of 7th March despite adverse headwinds for some of the way, passed by Casablanca, Morocco, on the morning of 8th March, then turned back westwards over the Cape Verde Islands towards the Caribbean, eventually landing at Naval Air Station Key West, Florida, on the evening of 15th March. The flight had covered a distance of 9,448 mi (15,205 km) in 264.2 hours, and in doing so had not only broken the lighter-than-air distance record of 6,980 mi (11,233 km) set by the Graf Zeppelin rigid airship in 1929 but also the aircraft endurance record without refuelling.One of the ZPG-2 airships was built or modified with external engines to test systems for the follow on ZPG-3W airships and is some times referred to as a ZPG-2 1/2.The follow-on and larger AEW blimp was the ZPG-3W, the largest non-rigid airship ever built. It was used to fill radar gaps in the North American early-warning network during the Cold War between the Contiguous Barrier and the Inshore Barrier. The popular name for the ZPG-3W was Vigilance. The ZPG-3W was unique in that the huge antenna for the early warning radar was enclosed inside the helium-filled envelope. Four airships were delivered to the U.S. Navy.The first flight of the ZPG-3W was in July 1958. The envelope of the blimp was used as a radome for the 42 ft (12.8 m) radar antenna, thus providing the airship with a clean aerodynamic shape. The airship was over 400 ft (121.9 m) long and was almost 120 ft (36.6 m) high. The endurance time of the airship could extend for days.The ZPG-3W Vigilance was the last of the airships built for the U.S. Navy. The July 6, 1960, crash of a Lakehurst-based airship east of Long Beach Island killed 18 sailors, a loss that added pressure on the program. The Navy subsequently decommissioned its airship units at Naval Air Station Glynco, Brunswick, Georgia, and at Lakehurst on October 31, 1961. On August 31, 1962, the last two ZPG-3W ships made a ceremonial last flight over Lakehurst — the base log noted, "This flight terminates operation of non-rigid airships at Lakehurst," Steingold said.The specially designed and built AN/APS-70 Radar with its massive 42 ft (12.8 m) internal antenna was the best airborne radar system built for detecting other aircraft because its low frequency penetrated weather and showed only the more electronically visible returns. A large radome on top of the envelope held the height-finding radar.In 1986, a ZPG-2W envelope was used for the construction of the Piasecki PA-97 Helistat.".
