The Lockheed Model 33 Little Dipper, also known as Air Trooper, was an American single-seat monoplane, designed by John Thorp and built by Lockheed at Burbank, California. Flown in 1944 and offered to the Army as a "flying motorcycle", it was evaluated as a potential entry for Lockheed into the civilian market, but the program was cancelled before the second prototype was completed.
The design of the Model 33 originated with a private venture for a two-seat light aircraft by John Thorp, a Lockheed engineer. [1] In April 1944, the company agreed to build the aircraft as the Lockheed Model 33. [1] Due to wartime restrictions on materials, [1] the company gained the interest of the United States Army in the aircraft as an "aerial flying motorcycle" to equip a "flying cavalry" under the name Air Trooper. [2] The Army, willing to entertain the concept, authorized Lockheed to build two prototypes of the Model 33. [1]
The Model 33 was of ordinary light-aircraft design, with a low-mounted cantilever monoplane wing and conventional empennage; powered by a 50 hp (37 kW) Franklin 2A4-49 engine, it was fitted with a fixed tricycle landing gear and proved to have STOL performance. [1]
The Model 33 prototype first flew in August 1944. [1] The handling characteristics of the aircraft were considered satisfactory, [3] but the Army had lost interest in the concept, [1] despite the prototype demonstrating its performance by landing and taking off again in the courtyard of the Pentagon. [4] Lockheed had intended to market the type as an inexpensive light aircraft on the civilian market as the Little Dipper; with the military interest having evaporated, the prototype and the partially completed second aircraft were scrapped in January 1947 for tax reasons. [1]
Thorp, the aircraft's designer, would go on to develop the Thorp T-211 with lessons learned from the Little Dipper project. [5]
