Douglas B-26 Invader

Douglas B-26 Invader. The Douglas B-26 Invader was a twin-engine medium bomber used by the United States Army Air Forces during World War II and later by the United States Air Force and United States Navy. Developed by the Douglas Aircraft Company, the B-26 Invader was designed to replace the Martin B-10 and Douglas B-18 Bolo. The aircraft's development involved notable figures such as Donald Wills Douglas Sr. and Edward Curtis Wells, who played crucial roles in the design and production of the B-26 Invader at the Douglas Aircraft Company facilities in Santa Monica, California, and Tulsa, Oklahoma.

● Design and Development

The design of the B-26 Invader was influenced by the North American B-25 Mitchell and the Martin B-26 Marauder, with the goal of creating a more efficient and effective bomber. The B-26 Invader featured a laminar flow wing designed by National Advisory Committee for Aeronautics (NACA) and a General Electric turbocharger. The aircraft's development was also shaped by the experiences of Carl A. Spaatz and Ira Eaker, who recognized the need for a more advanced bomber. The B-26 Invader underwent significant testing at the Muroc Army Air Field and the Wright Field, with notable test pilots such as Chalmers Goodlin and Robert M. Love contributing to the aircraft's development.

● Operational History

The B-26 Invader saw extensive action during World War II, participating in key campaigns such as the North African Campaign and the Pacific Theater of Operations. The aircraft was used by notable units such as the 320th Bombardment Group and the 17th Bombardment Group, with distinguished pilots like James H. Doolittle and Curtis LeMay flying the B-26 Invader. The B-26 Invader also played a significant role in the Korean War, with the 3rd Bombardment Wing and the 452nd Bombardment Wing operating the aircraft. The B-26 Invader was also used by the French Air Force during the First Indochina War, with notable French pilots like Pierre Mendès France and René Coty flying the aircraft.

● Variants

Several variants of the B-26 Invader were developed, including the B-26B, B-26C, and B-26G. The XB-26H and XB-26J were experimental variants, while the A-26 Invader was a ground-attack aircraft version. The JD-1 Invader was a target tug variant used by the United States Navy, with the ON Mark Engineering company modifying the aircraft for this purpose. Other notable variants included the B-26K, which was used by the CIA for covert operations, and the U-26, which was used for liaison and transport duties.

● Operators

The B-26 Invader was operated by several countries, including the United States, France, and United Kingdom. The aircraft was also used by the Royal Air Force and the Royal Canadian Air Force. Other notable operators included the Brazilian Air Force, the Cuban Air Force, and the Dominican Air Force. The B-26 Invader was also used by various airlines, such as National Airlines and Pan American World Airways, for cargo transport and passenger transport.

● Specifications

The B-26 Invader had a length of 51 feet 6 inches and a wingspan of 70 feet 6 inches. The aircraft was powered by two Pratt & Whitney R-2800 engines, which provided a top speed of 355 miles per hour. The B-26 Invader had a range of 3,000 miles and a service ceiling of 22,000 feet. The aircraft was armed with six M2 Browning machine guns and could carry up to 4,000 pounds of bombs. The B-26 Invader's performance was also influenced by the NACA 65-415 airfoil, which was designed by the National Advisory Committee for Aeronautics.

● Surviving Aircraft

Several B-26 Invaders have survived to the present day, with many on display at museums such as the National Museum of the United States Air Force and the Pima Air & Space Museum. The United States Air Force Museum and the National Naval Aviation Museum also have B-26 Invaders on display. Some surviving aircraft are still airworthy, with the Confederate Air Force and the Commemorative Air Force operating B-26 Invaders for airshows and historical reenactments. Notable surviving aircraft include the 44-34313, which is on display at the Museum of Aviation, and the 44-34718, which is operated by the Warbird Heritage Foundation.
