McDonnell F3H Demon

The McDonnell F3H Demon was a subsonic swept-wing United States Navy carrier-based jet fighter aircraft. After severe problems with the Westinghouse J40 engine that was ultimately abandoned, the successor to the F2H Banshee served, starting in 1956, redesigned with the J71 engine. Though it lacked sufficient power for supersonic performance, it complemented daylight dogfighters such as the Vought F8U Crusader and Grumman F11F Tiger as an all-weather, missile-armed interceptor until 1964. It was withdrawn before it could serve in Vietnam when it, and ultimately also the Crusader, were replaced by the extremely successful McDonnell Douglas F-4 Phantom II. McDonnell's Phantom, which was equally capable against ground, fighter and bomber targets, bears a strong family resemblance, as it was conceived as an advanced development of the Demon. The supersonic United States Air Force F-101 Voodoo was similar in layout, but was derived from the earlier XF-88 Voodoo, which also influenced the Demon's layout.

Development

Development work began in 1949, using a swept wing from the start rather than adapting a straight-winged design as was done with the Grumman F9F Panther. A competing contract was also awarded for the delta wing Douglas F4D Skyray. The Skyray, with a top speed of 722 mph (1,162 km/h), would become the Navy's first fighter to fly supersonic in level flight, while the Demon would never reach that level of performance. Departing from its tradition of using two engines, the Demon would be McDonnell's only single-engined carrier-based fighter, adopting under some Navy pressure, the Westinghouse J40 engine. That engine was being promoted by the Navy for its next generation of aircraft, and was to have thrust of over 11,000 lbf (49 kN)—three times that of the engines in the F2H Banshee. It was the first swept-wing design produced by McDonnell and among the first U.S. aircraft to have missile armament.

The Navy desperately needed a high performance fighter to meet the challenge of the swept-wing MiG-15 encountered over Korea. Production of the F3H-1N was hastily ordered even before the first flight of the XF3H-1 prototype on 7 August 1951 by test pilot Robert Edholm. The first test flights of the operational design did not occur until January 1953, when the Korean War was winding down.

The F3H Demon was originally designed around Navy's ambitious new Westinghouse J40 which was to offer enough power to use just one engine in a number of new aircraft designs. But the engine would ultimately fail to produce the promised thrust or run reliably. The engine was a major disappointment, producing only half of the expected power. Worse, it was temperamental and unreliable. Of 35 F3H-1N aircraft flown with the J40 engine, eight were involved in major accidents. The first production Demons were grounded after the loss of six aircraft and four pilots.Time Magazine called the Navy's grounding of all Westinghouse-powered F3H-1 Demons a "fiasco", with 21 unflyable planes that could be used only for Navy ground training at a loss of $200 million.One high point of the J40 was the 1955 setting of an unofficial time-to-climb record, in a Demon, of 10,000 feet (3,000 m) in 71 seconds.The proposed F3H-1P reconnaissance version was never built. The J40 program was terminated sometime in 1955.

All the aircraft it was to power were either canceled or redesigned to use other engines, notably the J57 and the J71. The F4D Skyray had been designed to accept larger engines in case the J40 did not work out, and was eventually powered by the Pratt & Whitney J57. 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. The best alternative turned out to be the Allison J71 engine which was also used in the Douglas B-66 Destroyer . Subsequent F3Hs with this engine were designated the F3H-2N. In service, the J71 proved problematic, providing insufficient power for an aircraft of the Demon's size. The engine also suffered from frequent flameouts and compressor stalls. The first Demon with a J71 flew in October 1954. Another significant problem was the reliability of the ejection seats: initial versions were found to be unreliable and were eventually replaced with Martin-Baker ejection seats that were becoming the standard Navy seat of choice due to their higher performance at low altitude and better reliability.

Despite the problems, the Navy ordered 239 F3H-2s, and the first were deployed in March 1956. 519 Demons were built up to the end of production in November 1959. It was not the Navy's first all-weather interceptor with radar (the AN/APG-51 air interception set was used first on the F2H-4 Banshee). The F3H-2 Demon had the AN/APG-51A, later upgraded to the 51-B version with a tunable magnetron then on to 51-C with better counter-measures in the receiver.

The F3H-2N's standard armament was four 20 mm (.79 in) Colt Mk 12 cannons. In later years, the upper two cannons were often omitted to save weight. Later models, redesignated F3H-2M, were equipped to fire the Raytheon AAM-N-2 Sparrow and later the Sidewinder air-to-air missiles. Deployed aircraft carried both types of missiles, the Sparrow on the inboard rails and the Sidewinder outboard. Cannons were not used in carrier air defense applications, but they were installed and armed when situations (such as the Cuban Missile Crisis) dictated, and where the aircraft might be deployed against surface targets.

A reconnaissance version, the F3H-2P, was proposed, but never built. It remained the Navy's front-line fighter until 1962, when it was succeeded by the F-4 Phantom II (which was a development of a proposed "Super Demon", a larger and much heavier version of the F3H). Developed during the Korean War to counter the MiG-15, it did not claim any aerial victories with missiles or dogfights, although it flew over Lebanon and Quemoy in 1958.

In 1962, the F3H was redesignated F-3. The F3H-2N became the F-3C, while the F3H-2M became MF-3B and the F3H-2 simply F-3B.

The last Demon-equipped squadron, VF-161 'Chargers', traded their F-3s for F-4 Phantom IIs in September 1964.

Due to excellent visibility from the cockpit, the Demon earned the nickname "The Chair". Demon pilots were known colloquially as "Demon Drivers" and those who worked on the aircraft were known as "Demon Doctors". The unfavorable power-to-weight ratio gave rise to the less flattering nickname "lead sled," sometimes shortened to "sled".

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
