The Vultee P-66 Vanguard was an accidental addition to the USAAF's inventory of fighter aircraft. It was initially ordered by Sweden, but by the time the aircraft were ready for delivery in 1941, the United States would not allow them to be eported, designating them as P-66s and retaining them for defensive and training purposes. Eventually, a large number were sent to China where they were pressed into service as combat aircraft with indifferent results.

Design and development

The Vultee Vanguard was the product of an idea conceived in the late 1930s by the Vultee Aircraft Division of the Aviation Manufacturing Corporation of developing four aircraft designed for different roles from a set of common wings and aft fuselage and tail assemblies. The company assigned four model designations: V-48 to a single seat fighter, BC-51 to a basic combat trainer, B-54 to an advanced trainer, and BC-54D as a basic trainer. Eventually the BC-51 would become the Army Air Corps BC-3 and the BC-54D, the BT-13.

In 1938, Richard W. Palmer started the detailed design of the V-48 fighter member of the quartet. The aircraft featured a metal covered, semi-monocoque fuselage and fully retractable landing gear powered by a Pratt & Whitney R-1830 radial air-cooled engine. During construction of the first prototype, a decision was made to lengthen the propeller shaft and install a tight cowling to provide a pointed nose to reduce drag. The first aircraft flew in September 1939, and was assigned registration number N21755. The fighter was named the Vanguard.

Flight tests revealed the aircraft was suffering from inadequate cooling. Measures to modify the cooling ducting were of little avail. After re-evaluating the design, and noting that the insignificant drag decrease was not worth the added weight and ducting problems, the second prototype, which was assigned the model number V-48 and registration N19999, was modified with a conventional cowl and the first aircraft were similarly modified. The second aircraft first flew on 11 February 1940. As a result of flight tests, a number of changes were made to the design including substantially increasing the areas of the horizontal and vertical tail surfaces.

Operational history

On 6 February 1940, the Swedish government ordered 144 Vanguards as the V-49C. The production prototype flew on 6 September 1940. The model V-49C was similar to the V-48 ecept for installation of a later version of the R-1830 engine with better higher altitude performance and provision for four 0.3 in (7.62 mm) wing mounted machine guns and two 0.5 in (12.7 mm) fuselage guns.

When production deliveries began in September 1941, the U.S. government placed an embargo on eporting the aircraft to Sweden. In the aftermath of Pearl Harbor, all Vanguards were assigned the designation P-66. Production ended in April 1942. Approimately 50 aircraft were retained by the USAAF and primarily used at pursuit training bases in the western U.S. and were deployed to the 14th Pursuit Group in defensive roles.[1] Although pilots were impressed by the P-66's handling, the type was considered less than robust and a tendency to ground-loop led to 15 aircraft being destroyed in landing accidents.

The British government took possession of 100 P-66s as the Vanguard I with plans to use the aircraft as an advanced trainer in Canada. After successful trials, however, the British then relinquished the aircraft to China where 104 Vanguards (including USAAC eamples) were shipped under the Lend-Lease program. They were originally intended to equip the 3rd American Volunteer Group, a fighter unit like the famed Flying Tigers; however, plans for additional groups were dropped after the Japanese attack on Pearl Harbor.

The Chinese received the assembled fighters via India by late 1942; Chinese Vanguards had USAAF insignia and serials as well as Chinese markings and Vultee serials on factory models. The undistinguished combat record of the Vanguard in China was due to problems that began in transit where a number of Vanguards were destroyed during tests in India and others lost while en route to China. Assembled P-66s were deemed unairworthy and abandoned at Karachi resulting in only 12 Vanguards on station at Kunming with the 74th Fighter Squadron of the 23rd Fighter Group, but this unit saw little action. Two Chinese squadrons from the 3rd Group and the 5th Group based at An-Su saw combat action with the Vanguard from August 1943 onward. However, many P-66s were destroyed on the ground during Japanese attacks while several were shot down in error when they were mistaken for the Nakajima Nakajima Ki-43 "Oscar" and Nakajima Ki-44 "Tojo". Although the Vanguard possessed a top speed of 340 mph (547 km/h), it was no match for the agile Japanese fighters in high-g maneuvers and relied on hit-and-run tactics against the Japanese.

The P-66 in Chinese service was largely replaced by Curtiss P-40s in 1943. A number of surviving P-66 Vanguards were placed in caves for storage at Chungking for use in the upcoming civil war against Mao's Communists. As late as 1947, many were reported still in their crates. [2]
