F8U / F-8 Crusader

Having gone from the height of success with the F4U Corsair to the unimpressive F6U Pirate and the unpopular F7U Cutlass, Vought finally scored a postwar victory with the F8U Crusader, the first purpose designed carrier jet fighter that was really technically competitive with its land based contemporaries.

The F4U and F7U-1 had suffered from poor pilot visibility on carrier landings, and no doubt with this in mind from the start, Vought's designers incorporated on the Crusader a two-position wing that would allow the aircraft's angle of attack to be increased without the nose having to be raised. The F8U's armament was initially comprised of a quartet of 20mm cannon and an (almost useless, and occasionally dangerous) retractable launcher on the lower fuselage for 2.75" unguided rockets.

Variants: F8U-1/F-8A: The first F8U-1s entered fleet service with VF-32 in the spring of 1957. As potent as the Crusader was, it was also something of handful, especially for pilots operating from the smaller SCB-27 ships, and losses throughout the aircraft's service life were high.

F8U-2NE/F-8E: Last new-build US version, with the capability of carrying underwing AGM-12s or bombs in the fighter-bomber role; J57-P-20A engine.

F-8E(FN): The only foreign customer for new-build Crusaders, and ultimately the last bastion of the type, France's Aeronavale chose the F-8 in 1963 to replace its long obsolete Aquilons. The Crusader itself was not on the cutting edge by that time, but the French needed an aircraft sized for regular operations from the Clemenceau class carriers, for which the F-4 would not be ideal. Even then, fairly extensive alterations had to be made to the F-8 to allow slower landing speeds, including BLC, increased droop for the ailerons and flaps, and larger horizontal tailplanes. By the late 1980s, the Crusader's effectiveness as a front line fighter was a thing of the past for the most part, although it was still effective in a close-in fight. Arrival of naval Rafales was still a way off, and many were advocating procurement of FA-18s as an interim measure. This was political non-starter, and the Aeronavale was forced to put 17 Crusaders through a limited upgrade program to keep them operating till the turn of the century. The resulting F-8Ps had the Sherlock RWR system (but no countermeasures fitted) rehabbed radar and electrical systems, and zero-zero ejection seats.

F-8J: Remanufactured F-8Es.

F-8K: Remanufacture of 87 F-8Cs.

F-8L: Remanufacture of 61 F-8Bs.

F-8P: 25 ex-USN F-8Hs refurbished for the Philippines; an additional ten aircraft were transferred for spares.

At War: The F-8 was involved from early on in the American combat involvement in Vietnam, with four Crusaders from the USS Ticonderoga strafing North Vietnamese torpedo boats during the first Gulf of Tonkin incident in August 1964. By the spring of the following year, US and NVAF aircraft had begun to duel, with an initial encounter between Hancock-based Crusaders and North Vietnamese MiG-17s resulting in damage to an F-8. The first Crusader victory was scored in June 1966 - the first of three MiGs that VF-211 claimed that month. In all, by 1972 Crusader pilots claimed 16 MiG-17 and three MiG-21 kills, against three aerial combat losses, although the North Vietnamese claimed 11 Crusader kills.

F8U-3: Really a completely different aircraft despite the common basic designation, the Crusader III was a significantly more powerful design, competitive with the F4H Phantom II. The -3 was powered by a P&W J75 fed through an angled intake, and a more powerful radar was fitted to guide the type's primary armament, a trio of AIM-7 Sparrows carried semi-conformally.

Advanced Projects:

Although the Crusader was well on its way out of front line US service by the early 1970s, strong vestiges of the F-8 design were still apparent in Vought's V-1100 lightweight fighter contender of the period, this being an F100 powered machine, that had it been built, would have been easily recognizable as a second generation F-8 of sorts.

F8C Helldiver

The first Curtiss aircraft to bear the sobriquet Helldiver, this type was derived from the company's F8C Falcon, but was intended as a carrier-based dive bomber rather than a fighter. The XF8C-2 and C-4 prototypes were followed up by twnety-five F8C-4 production machines powered by R-1340-C Wasps and capable of carryling a 500lb bomb on the centerline, or two smaller weapons underwing. The 65 C-5s were redesignated as O2C-1s for observation work, and were joined by thirty new-build models.

The XF8C-7 (1 example) and -8 (two aircraft) were testbeds with Wright Cyclones, these being redesignated as XO2C-2 and O2C-2s, respectively. The XF10C-1 model was further revised, retaining the Cyclone but adding a new tail and revised landing gear.

F7F Tigercat

Even as the US Navy was struggling to enter the monoplane age, it was also looking forwards to a new generation of aircraft far more powerful than the Grumman F4F then entering service. Grumman’s G-34, given the USN designation XF5F and first flown on 1 April 1940, was an unorthodox design with two Wright R-1820 engines and a twin tail. The Skyrocket lived up to its name, reaching speeds of 380mph, but was too radical a leap for the time, and no series production was undertaken. The XF5F did however give Grumman experience with twin-engine fighters, and within a year the company would be at work on the G-51, a much larger and more powerful aircraft able to operate from the planned Midway-class aircraft carriers.

The XF7F-2N was a -1 reworked as a night fighter prototype, with a nose-mounted set and space for a radar operator aft of the pilot. Thirty new-build aircraft were turned out by Grumman before production shifted to the R-2800-34 powered F7F-3, which also had an enlarged tail. Grumman built 189 standard -3s, and 13 -3N night fighters. The last new-build Tigercat was the carrier-capable F7F-4N, of which only 13 were built.

As there was some urgency in getting the F7F to the Pacific, it was decided that the type would first enter land-based service with the Marines. The F7F-2N did conduct carrier trials from the USS Antietam in the spring of 1945, but the Tigercat would primarily spend its career operating from land.

A single F7F, BuNo 80293, was supplied to the Royal Navy, and given the serial TT349, was used during trials at Farnborough.

Like some Avengers and Guardians from the same Grumman stable, a few F7Fs were to fly on as civilian fire bombers after being released from military service, with Sis-Q Flying Services / Macavia operating the type well into the 1970s.

The F7F served as the basis for Grumman’s TSF-1 design, an unbuilt torpedo bomber intended as a replacement for the TBF/TBM Avenger. The G-66 design’s Tigercat heritage was evident, although the fuselage was deepened, and span of the wings and tail planes was increased. A Mk.13 torpedo would be carried internally, and there were also to be a pair of under wing hardpoints. A TSF-1 cockpit mockup was produced, but the project got no further, being cancelled in January 1945. Emphasis shifted to the XTB3F project, which would mature as the AF Guardian postwar.

The Tigercat also influenced the design of the Grumman G-75, a jet night fighter in competition with the Douglas F3D Skyknight. Powered by a quartet of Westinghouse 24C turbojets, this aircraft would have carried its two-man crew in a side-by-side arrangement. The G-75 formed the basis for the revised XF9F-1N, which was actually ordered but cancelled before completion. The F9F-2 Panther that later flew was a completely different design.

EMD GP35

First turned out in the fall of 1963, the GP35 replaced the GP30 in the EMD catalog, and introduced a new angular cab design that would be standard on La Grange diesels for decades. The GP35 had the 567D3A prime mover rated at 2,500hp, and would be the last new-build Geep powered by a 567 variant.

US railroads bought 1,251 GP35s, while 83 other locomotives were built for Canadian and Mexican roads. Virtually all GP35s were built with low short hoods, but the Southern, Norfolk & Western, and NdeM bought high-nose units.

EMD also offered a non-turbocharged version, the GP28, in 1964-66. Only 31 examples were built, and 15 of those were for export to Mexico and Peru. Illinois Central was the major domestic customer, buying a dozen engines. Although GP28 sales were poor, many standard GP35s were later de-turbocharged to save on maintenance costs.
