In the early 1960's, meeting the need for a "counter-insurgency" aircraft, the USAF chosen On Mark Engineering Company of Van Nuys, California proposed the following major modifications to the already existing B-26 airframe: a complete remanufacture of the fuselage and tail assembly, an enlarged rudder, rebuilt and strengthened wings, re-engining with 2,500 hp P&W R-2800-52W engines, larger, fully reversible propellers with automatic feathering and clipped tips, full dual flight controls, two 165 gallon wing tip tanks, a full compliment of airborne electronics and more. This new aircraft was first delivered to the USAF in June of 1964 under the designation B-26K. Later aircraft had their cowlings revised with the air scoop being relocated further back on the cowl. By April of 1965, all forty B-26K Counter-Invaders had been delivered to the USAF.
