HISTORY



Detailing the development and operational history of the Beechcraft C-45 (Expeditor) Utility / Trainer Aircraft.  Entry last updated on 8/26/2017. Authored by Staff Writer. Content ©www.MilitaryFactory.com.
The Beechcraft C-45 was based on the Beech Aircraft Corporation's civilian-minded Model 18 "Twin Beech" series. First flight for the original company design was recorded on January 15th, 1937 and the aircraft was introduced that same year attempting to find its place in the peacetime market. Ultimately, with the onset of world war on the horizon, the US military adopted the Model 18 in many guises including the United States Army Air Forces (USAAF) which designated the type as the "C-45". It went on to become a fixture within the inventories of the USAAF (later the USAF), the US Navy and the USMC and saw additional service overseas with British and Canadian forces through Lend-Lease. In all, some 9,000 Model 18 aircraft were built covering 32 different variants in the family line. Production spanned from 1937 to 1970. While the Model 18 served as the basis for the C-45, it was also the origin of the "Navigator" and "Kansan" lines of the USAAF/USAF and the USN/USMC. The C-45 went on to see considerable operational service in World War 2 and the Korean War in the light transport, VIP transport and mission liaison roles.

Externally, the Model 18 was a basic design featuring a short nose assembly, framed cockpit position, tapered fuselage, low-set wing assemblies and a n H-style tail unit. The engines were fitted into streamlined nacelles at each wing leading edge. The undercarriage consisted of a tail-dragging arrangement to include two main landing gear legs and a tail wheel. Power was served through the pairing of Pratt & Whitney R-985 Wasp Junior radial piston engines of 450 horsepower each powering twin-bladed propellers. This supplied a maximum speed of 225 miles per hour with a cruising speed nearing 211 miles per hour. Range was out to 1,200 miles with a service ceiling of approximately 18,500 feet. The standard operating crew for a single C-45 was two pilots and up to nine passengers depending on the internal cabin configuration. Additionally, the cabin space could also be optimized for photo-reconnaissance equipment, MEDEVAC and light cargo-hauling. Overall, however, there proved no notable differences between the military C-45 and civilian Model 18 airframe.

The US Army Air Corps eventually placed orders for over 1,300 C-45 aircraft and, of these, most (1,137) were delivered in the C-45F configuration (seven-seat passenger transport). Other variants included the original C-45, the C-45A, C-45B, C-45C, C-45D, C-45E, C-45G and C-45H models - differing mainly in internal configuration and expected role. The "Expeditor II" and "Expeditor III" names were given to British (Royal Navy) and Canadian (Air Force) examples, respectively, under Lend-Lease.

After World War 2 and into the volatile 1950s, the US military charged Beechcraft with refurbishing some 900 C-45 airframes and these were reconstituted into USAF service as the C-45G (autopilot, R-985-AN-3 radial engines) and C-45H (sans autopilot, R-985-AN-14B engines) of which many went on to serve into the 1960s (approx. 1963). Some were assigned to Strategic Air Command (SAC).

Every branch of American service eventually fielded some form of the Model 18, such was the reach of this fine little airplane.
