During flight testing the engine proved to be inadequate so the Navy decided to equip the 61st and subsequent F3H’s with the Allison J Only later was support for the AIM-9 “Sidewinder” short-ranged AAM series included with the usual arrangement of two of each missile carried. The wing mainplanes were low-mounted along the fuselage sides and featured rounded tips. The J engine, which promised 10, to 11, lbs. The production ejection seats, which failed to function properly, caused a number of fatalities.

Air EnthusiastForty-three,pp. Development work began inusing a swept wing from the start rather than adapting a straight-winged design as was done with the Grumman F9F Panther.

Angelucci, Enzo and Peter M. In time, American technology and carrier doctrine allowed for a shifting of superiority in the Pacific Theater which ultimately led to the end of the war as a whole.

McDonnell F3H Demon

Areas covered include general ratings, speed assessments, and relative ranges based on distances between major cities. This development found greater numerical success in that of the line were produced for the United States and Canada became its only foreign operator. Inthe F3H was redesignated F As the Demon’s airframe was too small to fit any larger, more current and proven jet engine, the next batch of production fighters were delivered with the Allison J71 turbojet.

The Phantom was then followed into service by another jet-powered straight-winged type in the twin-engined F2H “Banshee”. The F3H-3 was a more powerful version of the Demon to take the General Electric J73 engine but this design was never realized. During World War 2the Japanese Mitsubishi A6M “Zero” fighter appeared and made possible a carrier-based fighter that outperformed its land-based rivals. McDonnell Aircraft Corporation Type: Despite the problems, the Navy ordered F3H-2 s, and the first were deployed in March This resulted in the initial “F3H-1N” production model which continued with the Westinghouse JWE engine of 7, lb thrust 10, lb with afterburner.


In service, the J71 proved problematic, providing insufficient power for an aircraft of the Demon’s size.

F3H Demon: The good, The Bad And The Ugly

As completed, the Demon was of an all-modern appearance with its pointed nosecone, near-slab-sided fuselage walls and beautifully swept-back wing surfaces. This entry’s maximum listed speed mph. The restructuring by the USAF led to a redesignation of all in-service Demon marks see variants listing. Amazingly, 25 brand new Demons were shipped to Naval Air Training Centers, fh they were used as training aids.

A competing contract was also awarded for the delta wing Douglas F4D Skyray. Between anda total of 23 Navy fighter squadrons flew versions of the F3H Demon. In later years, the upper two cannons were often omitted to save weight.

Early production F3H ‘s had a tendency to flame-out when flying in rain or icing conditions. With the end of the J40 engine demob and the subsequent grounding of the active F3H-1N fleet, the proposed “F3H-1P” photo-reconnaissance variant was not followed up on. The F3H was retired in But no other engine could simply be fitted into the old Demons, as both the wings and fuselage would have to be redesigned and enlarged. Data from The American Fighter [8]. The power of this one engine alone was seen as sufficient by USN authorities when compared to weaker twin-powered types seen previously and was to mark a new shift in USN aircraft propulsion.


A further were acquired as “F3H-2” fighter-bomber models cleared for carrying up to 6, lb of drop stores while also retaining the missile-launching dekon of the F3H-2M. The unfavorable power-to-weight ratio gave rise to the less flattering nickname “lead sled”, sometimes shortened to “sled”.

During flight testing the engine proved to be inadequate so the Navy decided to equip the 61st and subsequent F3H’s with the Allison J The J was promised by Westinghouse to have about twice the thrust of engines then in Navy service. Webarchive template wayback links Commons category link from Wikidata Articles with Internet Archive links Use dmy dates from December Nevertheless, the USN was in need of high-performance, frontline fighters and continued to push the F3H program along.

Patrick Stephens Limited, The dawn of the jet age also ushered in an all-new generation of fighter for the United States Navy USN and the McDonnell concern became a longtime contributor to the service branch with various designs introduced.
