The Martin B-33 was designed by the Glenn L. Martin Company as the Martin Model 190 and was a high-altitude derivative of the company's B-26 Marauder. Two different designs were developed first as a twin-engined aircraft and then as a four-engined aircraft. The four-engined version was ordered by the United States Army Air Forces but the program was cancelled before any aircraft were built.
Made by Glenn L. Martin Company.
It is the successor of the Martin B-26 Marauder .
