Beechcraft C45 Series for Sale — Classic Twin-Engine Military Transport
The Beechcraft C45 Series represents the military designation family of the legendary Beechcraft Model 18 twin-engine aircraft, one of the most significant and long-lived utility aircraft in aviation history. Produced from 1937 through 1970 and operated by virtually every major air force and many civilian operators worldwide, the C45 and its variants served in transport, navigation training, bombing training, and utility roles across every theater of World War II and continued in service for decades afterward. Today, surviving C45 and Beech 18 aircraft are prized warbird collectibles and flying classics that represent the pinnacle of prewar and wartime American aviation craftsmanship. Airplane Trade connects buyers and sellers of the Beechcraft C45 series through a dedicated marketplace for these historic aircraft.
Military C45 Variants and Service History
The military C45 designation encompasses several distinct variants of the Beechcraft Model 18 that served with the United States Army Air Forces, the United States Navy, and numerous allied nations during and after World War II. The C-45A through C-45H progression represented successive improvements in fuel capacity, powerplant specification, and equipment fit. The Navy designated their examples as the SNB series (SNB-1 through SNB-5), used primarily for navigator, bombardier, and multi-engine pilot training throughout the war.
More than 5,000 military Beech 18 variants were built for the USAAF and US Navy alone, with additional numbers delivered to Commonwealth nations, Nationalist China, and other Allied powers. After the war, many surplus C45s were declared excess to military needs and sold into the civilian market, where they became workhorses of the postwar commercial aviation industry and are the ancestors of the large civilian Model 18 fleet that continues flying today.

The C45 as a Warbird and Collectible
The Beechcraft C45 is among the most recognizable and historically significant twin-engine warbirds in the world. Its distinctive twin-tail configuration, radial engine sound, and classic 1940s lines make it an unmistakable presence at airshows and fly-ins. The large global fleet of Beech 18s — both civilian and ex-military — means that parts availability is better than for many rarer warbirds, and the Pratt and Whitney R-985 Wasp Junior engine has one of the most extensive overhaul and parts networks of any radial powerplant still in operational use.
Collectors value authentic C45 examples with verifiable military histories, original instrumentation, and period-correct paint schemes representing their service units. Many surviving aircraft have been restored to airworthy condition by dedicated owners and organizations with meticulous attention to historical accuracy, and these aircraft command premium prices when they come to market. Even partially restored or project-status C45s attract serious interest from experienced warbird buyers who see the restoration potential in these durable airframes.
Civilian Operation of the Beech C45
Beechcraft C45 aircraft operating on civilian registers typically hold FAA Experimental Exhibition or Standard certificates, with maintenance requirements varying accordingly. The R-985 Wasp Junior engine requires overhaul at 1,200-hour intervals and is supported by several certificated radial engine specialists in the United States and Canada. Tailwheel endorsement and multi-engine currency are prerequisites for C45 operation, and type-specific checkout from a qualified instructor familiar with the Beech 18 characteristics is strongly recommended before solo flight.
