TheBlackburn B-101 Beverley is aheavy transport aircraft produced by theBritish aircraft manufacturerBlackburn Aircraft. It was notably the only land-based transport aeroplane built by Blackburn, a company that otherwise specialised in producing naval fighter aircraft.
The Beverley was originally designed byGeneral Aircraft as theGAL.60 Universal Freighter, reflecting its intended use by both military and civil operators. The design process had started during theSecond World War, and drew upon theGeneral Aircraft Hamilcar glider. A major design study was conducted in 1945, ahead ofSpecification C.3/46 being released by theAir Ministry. The company's proposal was accepted and the Air Ministry placed an order for one prototype. General Aircraft was absorbed by Blackburn during the late 1940s, who continued the project. On 20 June 1950, the first prototype conducted itsmaiden flight from the company'sBrough facility; it was Britain's second largest landplane at the time of the flight.
TheMinistry of Supply mandated specification changes during the flight test programme, which necessitated a second prototype be constructed to a modified design. On 1 October 1952, an initial order for 20 aircraft was placed on behalf of theRoyal Air Force (RAF). On 12 March 1956, the first productionBeverley C.1 was delivered toNo. 47 Squadron, stationed atRAF Abingdon. Between 1956 and 1967, the Beverley would be flown by six squadrons of theRoyal Air ForceTransport Command. With the RAF, the Beverley would be deployed to various corners of the globe, includingKenya,Bahrain, andVietnam. Despite ambitions to secure commercial customers for the type, Blackburn were unable to garner orders beyond those placed by the RAF. The final operational Beverley was withdrawn from RAF service during August 1967.
The origins of the Beverley can be traced back to the British aviation companyGeneral Aircraft; their chief designer F. F. Crocombe worked on the concept as early as 1939.[1] It had been envisaged that, in light of the intense demands of theSecond World War, large aircraft designed specifically for transporting bulky payloads would be immediately attractive to military planners. Furthermore, it was reasoned that such an aircraft would also have a future on the civilian market.[1] It was to be capable of operating as astrategic transport, moving materials and personnel between theatres, and as atactical transport, deploying straight to the front lines, as well. A greater understanding of tactical transport requirements was gained by wartime experiences, particularly in producing theGeneral Aircraft Hamilcar; these experiences fed into a design study that was completed in 1945.[1]
An early configuration for the transporter was of a twin-finned, four-engined, fixedundercarriage, pod-and-boom aircraft that had a detachable compartment.[1] This compartment, which heavily resembled the fuselage of the Hamilcar, was intended to be dropped while the aircraft was flown at a very low altitude (ten foot above ground level) to land on its own tracked undercarriage. In 1945, it was proposed for the aircraft to be powered by fourRolls-Royce Merlin engines, capable of carrying a payload of 20,000lb, and having an all-up weight of 75,000lb.[1] Several other configurations were studied, including both twin-engined and four-engined arrangements.[1] An alternative powerplant arrangement of fourBristol Herculesradial engines was also examined. Fixed freight compartments were also present. An enlarged design, powered by fourBristol Centaurus engines, carrying a 38,000lb payload, and possessing an all-up weight of 126,000lb, was produced; this was the closest subject of the design study to what would become the Beverley.[1]
During the late 1940s, theAir Ministry issuedSpecification C.3/46, which sought a medium-range tactical transport aircraft that would, amongst other criteria, have a payload capacity of 25,000lb, a service ceiling of 18,000ft, and be suitable for missions such as air-droppingparatroops,casualty evacuation,glider towing, and the air-dropping of heavy payloads.[2] The project was boosted byBristol Aeroplane Company's agreement to develop a version of the Centaurus engine with a two-speedsupercharger, capable of producing up to 1,950lb. General Aircraft were issued with a prototype order from the Air Ministry, the company came to refer to the project as theGAL.60 Universal Freighter to reflect its intended use by both military and civil operators.[2]
Construction of the first prototype was undertaken at General Aircraft'sFeltham, Middlesex factory. Following the company's merger intoBlackburn Aircraft, it was agreed that construction would continue at Feltham, but that, due to the unsuitability of the adjacentHanworth Aerodrome, it would be disassembled and transported by road to Blackburn's facility inBrough,Yorkshire, where it was reassembled.[3] On 20 June 1950, the first prototype conducted itsmaiden flight, piloted by chief test pilot HaroldTim Wood; the flight was reportedly trouble-free. At the time of the flight, it was Britain's second largest landplane (the largest being the prototypeBristol Brabazon).[4]
Within four weeks of first flying, the first prototype had flown 21 flights and completed all preliminary handling, performance, and load tests.[4] In September 1950, it was first exhibited to the public at theFarnborough Airshow, where an order for a second prototype was announced. Thereafter, it was flown toRAF Boscombe Down for evaluation by theAeroplane and Armament Experimental Establishment; handling trials were successfully completed within a relatively short period of three weeks.[4] The prototype participated in competitive trials against an AmericanFairchild C-82 Packet. It also demonstrated its ability to transport heavy loads, including a 30-seat coach and a ten-tonexcavator.[4]
The first prototype was promptly followed by a second, which was designatedGAL.65 to signify the modifications made from the original design. These changes were largely necessary due to specification revisions by theMinistry of Supply, which sought an increased all-up weight of 127,000lb, and the ability to carry up to 50,000lb payloads over short distances.[4] Amongst the design changes were the substitution of the door-and-ramp combination present at the rear of the aircraft in favour ofclamshell doors, while thetailplane boom received seating for 36 passengers. The Bristol Hercules radial engines of the first prototype were replaced with the newer Bristol Centaurus engines, which were furnished withreversible-pitch propellers; this arrangement led to the aircraft having a relatively short landing distance as well as the ability to reverse under its own power. The takeoff and landing distances with maximum load were 790 and 310 yards (720 and 280 m).[5]
On 14 June 1953, the second prototype performed its first flight.[6] It participated in various trials, including a demonstration air drop over an Army drop zone inAmesbury. Following the completion of testing, it was returned to Brough to be rebuilt into a production standard aircraft.[6]
On 1 October 1952, an initial order for 20 aircraft was placed on behalf of theRoyal Air Force (RAF), which designated it as theBeverley C.1 (Beverley, Cargo Mark 1).[7] The nameBeverley was officially given to the aircraft in December 1952. To accelerate production, Blackburn had several of the aircraft's subassemblies, including the accessory bays, undercarriage systems, and the clamshell doors, manufactured at the works inDumbarton.[8] Further orders were subsequently received by Blackburn, including for nine aircraft on 30 July 1954, eight more on 2 January 1956, and another ten aircraft were ordered on 24 September 1956, for a total order of 47 aircraft. All of the production Beverleys would be constructed at Blackburn'sBrough facility.
Several production aircraft participated in evaluations and test programmes.[9] Amongst these were its tropical trials, conducted inNorth Africa in the summer of 1955, and its winter trials, conducted inCanada during late 1955 and early 1956.[10] In December 1956, the first production Beverley performed arocket-assisted take off (RATOG) during short take off trials. On 23 April 1953, the Beverley received itscertificate of airworthiness.[11]
A total of 49 aircraft were produced, with the last Beverly being completed during 1958. Various proposals were studied by Blackburn for refined or reconfigured variants of the aircraft, but no other customers were ever secured for the Beverly. One specific customer that Blackburn had pursued in the civil sector wasSilver City Airways. It was envisaged that the aircraft would be operated as a cross-Channel car ferry, capable of carrying up to six cars and fivemotorcycles along with 42 passengers.[7] Other initiatives focused on civil freighter operators, with particular efforts being made in theMiddle East, including demonstrations involving the air-delivery of materials for theoil extraction industry.[12]
The Blackburn Beverley was a large transport aircraft, designed for carrying large and bulky payloads and landing on rough or imperfect runways, or dirt strips. In terms of its basic configuration, it was a high-wingcantilevermonoplane with a fixedundercarriage. The engines and associated accessories were installed in easily interchangeable bays on the lower surface of the wing.[13] The twin-spar wings comprised two separate sections that were bolted onto the fuselage. Simplicity and maintainability were key focus points of its design, thus the Beverley deliberately lacked bothpneumatics orcabin pressurisation.[2] The fuselage was divided into four main sections. The aircraft's exterior surface was primarily composed ofrivettedAlclad plating.[2] Relatively large low-pressureDunlop tyres were fitted to the single-wheel undercarriage, which reportedly gave a similar wheel loading to the much smallerDouglas DC-3.[14]
The fuselage directly attached to the tailboom and its large rectangular twin-fin tailplane. The cantilever tail surfaces were all-metal and featured adihedral to keep them clear of the inboard engine'sslipstream.[15] The tailboom permitted access to the rear of the fuselage through removable clamshell doors. A device called anElephant's Foot could be fitted under the centre of the fuselage just forward of the clamshell doors when loading heavy items to prevent the aircraft from tipping back.[16] The flight deck was positioned relatively high, and was accessed via a ladder in the forward portion of the hold.[15] It accommodated two pilots seated in a side-by-side arrangement, who had favourable downwards visibility due to the shaping of the nose; behind them were the navigator and radio operator, seated back-to-back on bench-style seating. All of the flight controls werehydraulically-augmented to reduce pilot fatigue, although manual reversion was possible.[15]
A 36 ft (11 m) rectangular main fuselage space was supplemented by passenger accommodation in the tailboom. The main cargo hold had a volume of about 6,000 ft3 (170 m3), which could accommodate 94 troops, with another 36 in the tailboom.[14] The floor, composed of light alloy, was corrugated and stressed to take distributed loads of 325lb per square foot. Various payloads could be carried, including numerous vehicles. In one configuration, a maximum of nineJeep-style road vehicles could be carried, a single fully-fuelledbulldozer could also be transported.[14]Paratroopers in the upper passenger area jumped through a hatch in the base of the boom just in front of the leading edge of the tailplane; paratroopers were also able to exit the cargo hold through the side doors. The Beverley was equipped with toilets, which were situated in the tail beyond the paratroop hatch located on the floor of the tailboom. Following a fatal incident where a serviceman fell twenty feet to the ground while exiting the toilet, unaware that the paratroop hatch had been opened, modifications were made to prevent the toilet doors from being opened while the paratroop hatch was open.[16]
On 29 January 1955, the first production Beverley from an original order for 20 aircraft made its first flight. This same aircraft was delivered toNo. 47 Squadron, stationed atRAF Abingdon, on 12 March 1956. The type was quickly used to establish regular freight services toRAF Wildenrath in Germany.[17] Upon its entry to service, it was the largest aircraft operated by the RAF. It became commonly regarded as being "ungainly but highly effective" and was described byAir Chief MarshalSir Robert Freer as "like something out of the Ark, but it was a superb supply dropper."[18]
During early 1957, No. 53 Squadron, which was also based at RAF Abingdon, received its first Beverleys; it was absorbed into No. 47 Squadron in June 1963. Its introduction allowed for the retirement of theHandley Page Hastings.[19] During February 1966, No. 30 Squadron started performing its most distant assignment to use the type, delivering humanitarian aid and other supplies toDa Nang,Vietnam.[20] The squadron continued operating the Beverley until October 1967, at which point the squadron disbanded.
During April 1957, No. 30 Squadron received its Beverleys, being initially based atRAF Dishforth. In June 1958, it participated in airlift operations toIraq in response to acoup d'état.[21] The squadron and its Beverleys would be subsequently deployed toRAF Eastleigh,Kenya andRAF Muharraq,Bahrain. In the former deployment, it assisted in efforts to combat theMau Mau rebellion and to supportOperation Vantage.[21] No 30 Squadron was disbanded during September 1967. Initially, the aircraft were silver overall, but later, those operated by the squadrons based in the Middle East were given an overall sand camouflage finish.
The longest-serving Beverleys were those operated by No. 47 Squadron in the UK, which was active between 1956 and 1967. During October 1960, No. 34 Squadron received its aircraft; based atRAF Seletar, it would fly the Beverley until the end of 1967.[22] During this time, No. 34 Squadron carried out flood relief work inSouth Vietnam. Prior to this, from June/July 1959, the first four Beverleys to go to theFar East formed the Beverley Flight, No. 48 Squadron, based atRAF Changi.
During 1958,No. 84 Squadron became the sixth squadron to fly the Beverley. Based atRAF Khormaksar,Aden, the type was active during theAden Emergency, providing airlifts and supply drops to British andSaudi Arabian forces stationed in the region.[21] No. 84 Squadron and the Beverley alike provided crucial logistical support during theBrunei revolt of 1962. By July 1963, the squadron's Beverleys had reportedly flown almost two million miles while conveying over 20,000 tons of freight and 60,000 passengers.[21] During August 1967, No. 84 Squadron exchanged its remaining Beverleys for the newer but smallerHawker Siddeley Andover.[23]

Nine aircraft were lost in service with the RAF, including one in theSutton Wick air crash. Two were written off after being damaged by explosive devices (one landmine, one bomb).
Only a single Beverley has survived: the first production aircraft,XB259 was on display atFort Paull, just east ofHull, in England, but was sold at auction in September 2020 and then partly dismantled for a proposed move to the nearby formerRAF Riccall.[26] In late January 2024, theSolway Aviation Museum acquired the aircraft and launched a £60,000 appeal for donations to cover the costs of further dismantling work then transporting the aircraft to Carlisle for restoration and permanent display there.[27]
Three other aircraft survived (two on public display) until 1977, but all were subsequently scrapped:
