History

 
The Beech C-45 Expeditor was a military version of the civil Beechcraft Model 18 light transport aircraft, one of the most adaptable and versatile twin-engined aircraft built by the USA. The type first flew in 1937 and orders for military versions were placed in 1941 with a total of 5024 being delivered during the war in the variants: AT-7, AT-11, UC-45, C-45, JRB and the SNB.

They were produced, for example, as an advanced trainer in 1941 under the designation AT-7 "Navigator." Many, as C-45Bs, served as transports. Large numbers were lend-leased to the British who called them MK 1 "Expeditors." Yet another version, identifiable by its glassed-in nose, was produced as the AT-11 "Kansan" for training bombardiers. A model fitted out for photographic duties was called the "Discoveror." SNB was the US Navy designation, the latter also called the "Bugsmasher" as it was affectionately named by the USN.

236 Expeditors were supplied to the RAF, RCAF and an additional 73 served with the Royal Navy's Fleet Air Arm under lend-lease. The allied air forces used them in a wide variety of roles including navigational training, bombing and gunnery training, utility transport, search and rescue and aerial photography. As a passenger transport, they were typically configured to carry six people.

Ordered by the US Navy in 1940, the intended use of the C45 as a photography platform was expanded to include administrative and logistic support, the transport of patrol aircraft crews, and as a training aircraft for photo reconnaissance crews. Pilots not assigned to operational squadrons relied on the SNB, to maintain flying proficiency for the purpose of collecting "hazardous duty" pay. As a result, SNB time appears in the log books of most Naval Aviators during the course of the aircraft's thirty years service.

Expeditor C-45 No. 435 of the USAF postwar

The Fleet Air Arm ordered 73 Expeditor CI and CII under Lend-Lease contract No AC-40082 and AC-3213. The first Expeditor, FT985, was delivered to US NAS Anastocia in February 1944 for the British Embassy  in Washington DC, and subsequently others delivered to TOC RN Cochin 13 May 1944 (eg FT982).

The first second-line squadron to receive the Expeditor was 782 squadron at Donibristle from 21 May 1944 (eg FT979, and many were subsequently delivered to 742 squadron at Coimbatore/Sulur throughout 1944 and into 1945. One Fleet Air Arm Expeditor KP110 of 782 squadron detached at  Lee-on-Solent served as the Admiral's barge during August and September, 1945. Others were given individual names by 782 squadron, including :"Merlin 20" (FT977), "Merlin 23" (HB162) and "Merlin L" (HD760).

The type saw service until after the end of WW2 and some returned to the USN in March 1946.

Surviving aircraft and relics
There are a number of Expeditors and other Beech 18 marks in existence around the world, although probably less than ten in Airworthy in Europe and Canada. The single airworthy Expeditor on the European display circuit is G-BKGL rebuilt by ARC at Duxford (UK), static examples are also at the Canadian Warplane Heritage Museum, Nanton Museum (Canada), and the Aero Space Museum Association of Calgary. A number are also exhibited in Europe and in the USA.
