    From many request to see Scorpion from my desk below is update picture


    The Northrop F-89 Scorpion was an early American jet-powered all-weather interceptor. It has the distinction of being the first aircraft armed with nuclear weapons (the Genie missile) for air-to-air use.

    The Scorpion stemmed from a 1945 United States Army Air Forces specification for a jet-powered night fighter to replace the P-61 Black Widow. Lockheed submitted a modified version of the T-33 to be produced as the F-94A. Northrop submitted a proposal labeled N-24, a slim-bodied aircraft with a cantilevered mid-mounted wing and two Allison J35 turbojet engines with afterburners. It was to have radar and a crew of two, with an armament of six 20 mm cannon in a unique trainable nose turret. Contracts for two prototypes were issued in December 1946.

    The initial XP-89 prototype made its first flight on 16 August 1948, with test pilot Fred C. Bretcher. A unique feature added to the prototype during development was the deceleron, a two-part aileron that could split open to act as an air brake; this feature was to become a Northrop trademark, still used today on the B-2 Spirit.

    Production was authorized in January 1949, with the first production F-89A entering USAF service in September 1950. It had AN/APG-33 radar and an armament of six T-31 20 mm cannon with 200 rounds per gun. The swiveling nose turret was abandoned, and 300 US gallon (1,100 L) fuel tanks were permanently fitted to the wingtips. Underwing racks could carry 16 five-inch aerial rockets or up to 3,200 lb (1,455 kg) of bombs.

    Only eight F-89As were completed before the type was upgraded to F-89B standard, with new avionics. These had considerable problems with engines and other systems, and soon gave way to the F-89C. Despite repeated engine changes, problems persisted, compounded by the discovery of structural problems with the wings that forced a refit of 194 -A, -B, and -C models.

    The major production model was the F-89D, which first flew 23 October 1951 and entered service in 1954. It removed the cannon in favor of a new Hughes E-6 fire control system with AN/APG-40 radar and an AN/APA-84 computer. Armament was two pods of 52 2.75 in (70 mm) "Mighty Mouse" FFAR rockets, for a total of 104. A total of 682 were built.

    Proposed re-engined F-89s, designated F-89E and F-89F, were not built, nor was a proposed F-89G that would have used Hughes MA-1 fire control and GAR-1/GAR-2 Falcon air-to-air missiles like the F-102 Delta Dagger.

    The subsequent F-89H, which entered service in 1956, had an E-9 fire control system like that of the early F-102 and massive new wingtip pods each holding three Falcons (usually three semi-active radar homing GAR-1s and three infrared GAR-2s) and 21 FFARs, for a total of six missiles and 42 rockets. Problems with the fire control system delayed the -H's entry into service, by which time its performance was notably inferior to newer supersonic interceptors, so it was phased out of USAF service by 1959.

    The final variant was the F-89J. This was based on the F-89D, but replaced the standard wingtip missile pod/tanks with 600-gal fuel tanks and fitted a pylon under each wing for a single MB-1 Genie nuclear rocket (sometimes supplemented by up to four conventional Falcon air-to-air missiles). The F-89J became the first and only aircraft to fire a live Genie as the John Shot of Operation Plumbbob on 19 July 1957. There were no new-build F-89Js, but 350 -Ds were modified to this standard. They served with the ADC through 1959 and with the Air National Guard through 1969.

    A total of 1,050 Scorpions of all marks were produced.

    Alright! :thumb:

    This meets all my criteria for what I call a REAL JET..............

    Straight wings............(swept wings are ok I guess)

    Wingtip tanks.............

    Flew in the 1950's.......

    All these new planes with the weird shapes and and things being stuck inside aren't jets............... they are aircraftsign1

    Thanks Nobi!

    Hi Nobi-
    Two other questions:
    1) Will both the colored version and a black and white version also be available?
    2) Can a file be made available that would allow enlagement to about 1/10 scale without having thickened lines.

    As you can tell this will be a popular Plane and I think you will see many interested in it. Thank You Nobi for your efforts related to this plane.

    All of my model will come with color version but I can send black and white model if customer request

    My model is in vector base model that mean you can import model into vector base graphic program like Coreldraw and rescale without having a thickness line

    Update progress today...all parts arrange into letter size paper wait for strip and then test build


    anybody know F-89 have a low-vis scheme or not, thank you very much in advance
