POWER PLANT: Four Westinghouse J34-WE-7 turbojet engines, rated at 1,360 kp. thrust each
PERFORMANCE: 520 mph at 30,000 ft
COMMENT: The XF-87 was the last aircraft built by Curtiss Aircraft. The specification originally called for a twin-engine, single-seat fighter, which evolved into an attack aircraft (XA-43) and finally to a quad-jet, twin-place, all-weather, high-altitude fighter. Two prototype XF-87s were built, the second of which was modified to the sole XF-87A. The XF-87 was designed for an innovative nose turret capable of swiveling in a wide arc around the axis of flight; however, the turret was never actually installed on the XF-87. The very large fighter was severely underpowered by four J34 turbojets and was redesigned for two J47 turbojets (XF-87A). A production order for 58 XF-87As and 30 RF-87s was canceled before any aircraft were constructed (Ref.: 23).
TYPE: Heavy long-range bomber, in service as Assembly ship
ACCOMMODATION: Crew of four
POWER PLANT: Four Pratt & Whitney R-1830-43 Twin Wasp radial engines, rated at 1,200 hp each
PERFORMANCE: 303 mph at 25,000 ft
COMMENT: The Consolidated B-24D “Liberator” was the first variant to be qualified for combat. Under the original Production Pool plan, Consolidated/San Diego was the prime manufacturer, supplying components to Fort Worth and Douglas/Tulsa for assembly. In May, 1942 the first of 2,738 B-24D’s rolled off the assembly lines.
Due to rapidly changing needs, especially for defensive armament, there were many variations within the B-24D model, these differences identified by “production blocks” (e.g B-24D-70-CO). Nevertheless, B-24D’s have been very successful in the first years of bombing offensive in the European theater but later are replaced by B-24H and B-24J. These variants had more powerful engines and better defensive armament. Some bombardment groups used phased-out B-24Ds as assembly (formation) ships until the end of the hostilities. The B-24D Assembly (Formation) Ship “The Little Gramper” shown here belonged to the 491th Bombardment Group (H) „The Ringmasters“, stationed at North Pickenham. (Ref. 2)
POWER PLANT: One Pratt & Whitney R-2800-53 engine, rated at 2,000 hp
PERFORMANCE: 414 mph
COMMENT: In 1940 the Curtiss Aircraft Company proposed a new design for the eventual replacement for the Curtiss P-40. The new aircraft, the Curtiss XP-60, went through a long series of prototype versions with different engines. Installation of the British Rolls-Royce Merlin engines led to the development of the XP-53, soon redesignated XP-60. Delayed deliveries of the Merlin engines necessitated the installation of Wright (XP-63C) as well as Chrysler (XP-60B) engines. To improve the performance of the XP-60C the engine was changed again, this time a Pratt & Whitney R-2800 with contra-rotating propellers was installed. During its first flight the results were generally satisfactory. Changing the contra-props into a four-bladed propeller led to the XP-60E. But the performance was poorly, too, and further work on this design was abandonded. (Ref.: 8)
POWER PLANT: Two Allison V-3420 engines, rated at 3,000 hp each
PERFORMANCE: 436 mph at 25,000 ft
COMMENT: The Lockheed XP-58 Chain Lightning was an American long-range fighter developed during WW II. Although derived from the successful Lockheed P-38 Lightning, the XP-58 was plagued by technical problems with its various engines that eventually led to the cancellation of the project. Initially, the design was powered by two Continental IV-1430 engines. In July 1940, Lockheed decided to switch to Pratt & Whitney XH-2600 engines as the aircraft would be underpowered with the Continental engine. However, soon Lockheed was advised the development of the XH-2600 engine was terminated. So again engine alternatives were needed and the design was changed to use two Wright R-2169 Tornado engines. In February 1943, use of another engine, the Allison V-3420, was necessary due to poor progress with the Tornado engine development. Parallel to this the design was revised as a second crew member was added and the defensive armament was changed. Two turrets, one upper and the other lower on the fuselage, each containing two .50 in machine guns, were installed and directed by a gunner in the rear fuselage. The XP-58 finally flew on 6 June 1944 for the first time, but after 25 test flights were completed and clarified many more problems further work on the XP-58 was reduced and in October 1944 the program was stopped and no further flights were done. The construction of the second prototype was abandoned. (Ref.: 23)
POWER PLANT: 2 × Wright R-3350-43 Duplex Cyclone engines, rated at 2,300 hp each
PERFORMANCE: 370 mph at 17,000 ft
COMMENT: The Beechcraft XA-38 Grizzly was a ground attack aircraft, fitted with a forward-firing 75 mm cannon with 20 rounds mounted in a fixed position on the nose to attack heavily armored targets such as tanks and bunkers. Additionally, there were two forward firing machine guns. Defensive armament consisted of remotely controlled ventral and dorsal turrets directed by periscope sights. The first prototype flew on 7 May 1944 and the aircraft proved satisfactory in all respects and better than expected. But after testing it became obvious it would not be ready for the projected invasion of Japan, and furthermore it used the same engines required by the Boeing B-29 Superfortress which had priority. So no orders were given and the XA-38 program was canceled after two prototypes had been completed. (Ref.: 23)
TYPE: Heavy long-range bomber, in service as Assembly ship
ACCOMMODATION: Crew of four
POWER PLANT: 4 × Pratt & Whitney R-1830 Twin Wasp, rated at 1,200 hp each
PERFORMANCE: 290 mph at 18.482 ft
COMMENT: The Consolidated B-24 “Liberator” was a four-engine, heavy long-range bomber designed by the Consolidated Aircraft Company in the late 1930s. For that time it was a modern design compared with its main competitor, the better-known Boeing B-17 “Flying Fortress”. The first flight took place on December, 29th, 1939. The “Liberator” had a higher top speed, greater range, and a heavier bomb load than its rival. On the other hand the “Liberator” was more difficult to fly, with heavy control forces and poor formation-flying characteristics. Nevertheless, the B-24 provided excellent service in a variety of roles thanks to its large bomb load and long range and was used in the European as well as the Pacific campaign. When the production ended in 1945 more than 18.480 aircraft have been built, more than of all other bombers during WWII. (Ref.: 4)
The Consolidated B-24H Liberator shown here is an assembly (formation-) ship “The Spotted Ass Ape” of the 458th Bombardment Group (H), 8th USAAF, stationed at Horsham St Faith, England. (Ref.: 2)
NOTE: This aircraft is hand-painted direct onto the models surface, except the black dots. For these Polka (donut) dots I used Bishop precut tape shapes, solid donut pads, Bishop Graphics. Inc., Westlake Village, Ca 91359 U.S.A. These are self-adhesive, extreme thin, in black, and easy to apply. More work is required to red and yellow Polka dots. Here I used the solid donut pads from the same company, but in red. Unfortunately, these are transparent. So they need to be painted dot by dot before being applied.
POWER PLANT: Pratt & Whitney R-4360-31 Wasp Major, rated at 3,000 hp each
PERFORMANCE: 450 mph
COMMENT: The Hughes XF-11 was designed as a long-range reconnaissance aircraft. Its design based on the Hughes D-2, a fighter and bomber project of early 1940, and resembled somewhat to the Lockheed P-38 Lightning but was much greater. So it had a tricycle landing-gear, two engines, twin boom and a pressurized central crew nacelle. In 1943 the USAAF ordered 100 F-11s, but only two examples were completed immediately after WWII. The first aircraft crashed in 1946 with Howard Hughes at the controls and the second prototype was completed and successfully flown in 1947. (Ref.: 23)
POWER PLANT: Two General Electric J33-GE 5 turbojets, rated at 1,835 kp each
PERFORMANCE: 522 mph at 15,700 ft
COMMENT: The Bell XP-83 was a United States prototype escort fighter designed by Bell Aircraft during World War II. It first flew in 1945. As an early jet fighter, its limitations included a lack of power and it was soon eclipsed by more advanced designs. The early jet fighters consumed fuel at a prodigious rate which severely limited their range and endurance.
In March 1944, the United States Army Air Forces requested Bell to design a fighter with increased endurance and formally awarded a contract for two prototypes on 31 July 1944.Bell had been working on its “Model 40” interceptor design since 1943. It was redesigned as a long-range escort fighter while retaining the general layout of the Bell P-59 Airacomet. The two General Electric-GE-5 turbojet engines were located in each wing root which left the large and bulky fuselage free for fuel tanks and armament. The fuselage was an all-metal semimonocoque capable of carrying 4,350 l of fuel. In addition, two 950 l drop tanks could be carried. The cabin was pressurized and used a small and low bubble style canopy. The armament was to be six 12.7 mm machine guns in the nose.
Early wind tunnel reports had pinpointed directional instability but the “fix” of a larger tail would not be ready in time for flight testing. The first prototype was flown on 25 February 1945, demonstrating that the aicraft was under-powered and unstable. The limited flight testing provided satisfactory flight characteristics although spins were restricted until the larger tail fin was installed. The second prototype did incorporate the extended tail and an aileron boost system. One unique characteristic was the XP-83’s refusal to slow down due to its sleek aerodynamic shape and lack of drag brakes. This meant that test pilots were forced to fly “stabilized approaches” (i.e. very long and flat landing approaches).
The first prototype was used in 1946 as a ramjet test-bed with an engineer’s station located in the fuselage behind the pilot. The second prototype flew on 19 October and was later scrapped in 1947. Apart from range, the XP-83 was inferior to the Lockheed P-80 Shooting Star and this led to the cancellation of the XP-83 project in 1947 (Ref.: 24).
POWER PLANT: One Pratt & Whitney R-4360-10, rated at 3,000 hp
PERFORMANCE: 432 mph
COMMENT: The estimated excellent performance of this aircraft, designed for the US Navy, was of great interest for the US Army Air Force, too. So the third (of three) prototype was delivered to the US Army Air Force and tested at Eglin Air Force base. But the advent of new jet fighters led to the cancellation of many wartime piston-engined projects. So consequently, the USAF lost interest in pursuing the project and the prototype was scrapped.
POWER PLANT: One Pratt & Whitney R-4360-13 Wasp Major, rated at 3,450 h.p.
PERFORMANCE: 490 m.p.h. at 25,000 ft
COMMENT: The second prototype of the Republic XP-72, first flown on 26 June 1944, had Aero Products contra props in place of the four bladed propeller of the first prototype of the Republic XP-72.
