Today, three-quarters of a century after the first prototype Double Wasp, it still flies in restored vintage warbird aircraft displayed at air shows — such as the over two dozen airworthy examples of the first airframe design it powered, and sees service worldwide on aircraft such as the Canadair CL-215 water-bomber. In addition, R-2800s continue to power DC-6 cargo and fuel-carrying aircraft in locations such as Alaska. A total of 125,334 R-2800 engines were produced between 1939 and 1960.[1]
