Saunders-Roe Princess G-ALUN displaying at the Farnborough SBAC Show in September 1953
The name was adopted in 1929 after Alliott Verdon Roe (see Avro) and John Lord took a controlling interest in the aircraft and boat-builders S. E. Saunders. Prior to this (excepting for the Sopwith/Saunders Bat Boat) the products were Saunders, the A4 Medina for example dating from 1926. Sam Saunders, the founder, developed the Consuta material used in marine and aviation craft.[3]
The Saunders-Roe interest in aviation didn’t prevent the firm from continuing with the boatbuilding activities associated with S. E. Saunders Ltd.
In January 1931 Flight magazine revealed that Whitehall Securities[4] Corporation Limited acquired a substantial holding in Saunders Roe. Whitehall Securities was already a large shareholder in Spartan Aircraft Ltd, of Southampton, and arising out of this investment Spartan was effectively merged into Saunders Roe.
In 1938 Saunders-Roe undertook a re-organisation of the commercial and administrative sides of its business. First, the marine section, consisting of the shipyard and boat-building business, was transferred to a new company, Saunders Shipyard Ltd., all of the shares of which were owned by Saunders-Roe Ltd. Mr. C. Inglis was appointed shipyard manager. Secondly, the plywood section of the business carried on at the factory on the River Medina was transferred to a new company, Saro Laminated Wood Products Ltd., in consideration for a majority of the shares therein. Laminated Wood Products Ltd., which had marketed most of the plywood output, also merged its interests into the new company. Major Darwin, managing director, left the company. On the aircraft side of the business Mr. Broadsmith continued as director and general manager. All other senior posts in the executive staff remain unchanged.[5]
In 1947 they flew the SR.A/1 fighter prototype, one of the world's first jet-powered flying boats, and in 1952 they flew the prototype Princess airliner, but the age of the flying-boat was over and the two further Princess examples to be completed were never flown. No further new seaplanes were produced here. Modification work on Short-built flying boats continued at Cowes until 1955.
Saro works at East Cowes in September 1954 with stored Princess G-ALUN
The last fixed-wing aircraft they built was the experimental SR53 mixed-power interceptor.
In 1951 Saunders-Roe took over the interests of the Cierva Autogiro Company at Eastleigh including the Skeeter helicopter project. In September 1952 the company comprised:
Saunders-Roe Ltd. with a Head Office in Osborne, East Cowes, Isle of Wight (I.O.W.) with works at Columbine I.O.W. and Southampton Airport.
There was a branch design office in London, during the 1950s. It was situated in Queens Square, overlooking the Great Ormond Street Hospital for Children
Saunders-Roe (Anglesey) Ltd, Friars Works, Beaumaris, North Wales
In the same year Saro's helicopter and hovercraft interests were taken over by Westland Aircraft which continued the Skeeter family with the Scout and Wasp. In 1964 all the hovercraft businesses under Westland were merged with Vickers-Armstrongs to form the British Hovercraft Corporation. This, in turn, was taken over by Westland and was renamed Westland Aerospace in 1985, and hovercraft production was reduced to nearly nothing until the advent of the AP1-88. The company produced sub contract work for Britten-Norman, produced composites and component parts for the aircraft industry, especially engine nacelles for many aircraft including the De Havilland Canada "Dash 8", the Lockheed Hercules, the British Aerospace Jetstream and parts for the McDonnell-Douglas MD-11. By the mid-1990s, over 60% of the world's production of turboprop nacelles took place in the East Cowes works.
Gloster Saro Meteor light foam tender at Brooklands Museum
In the late 1960s/early 1970s the Saunders-Roe Folly Works, by then owned by Hawker Siddeley was merged with the Gloster works to form Gloster-Saro utilising both companies' expertise in aluminium forming to produce fire appliances and tankers in the Gloster factory at Hucclecote, mostly based on Reynolds-Boughton chassis. In 1984 Gloster Saro acquired the fire tender business of the Chubb group with the company merging in 1987 with Simon Engineering to form Simon Gloster Saro.
In 1994 Westland was taken over by GKN, and when GKN sold off its shares of Westland to form Agusta-Westland, it retained the East Cowes works, where it continues aircraft component design and production.
Laird (Anglesey) Ltd was formed in 1968 and incorporated the Beaumaris and Llangefni factories of Saunders-Roe and the engineering business of Birkenhead shipbuilders Cammell Laird. Laird developed the Centaur, which was half Land Rover and half light tank. The company is now known as FAUN Municipal Vehicles Ltd.having been taken over yet again. Today, FAUN manufactures portable aluminium roadways and runways at Llangefni under its TRACKWAY brand.[6]
MV Red Jet 3 docked at the Columbine, 19 August 2018
In 2015, the East Cowes Columbine Hangar, which later became notable for its large Union Jack painted on its doors, was leased from the Homes & Communities Agency to Shemara Refit, now known as Wight Shipyard Co. Ltd, to refit MY Shemara. They also constructed the catamaran ferry Red Jet 6 inside the hangar for Red Funnel Ferries, with the next in the series, Red Jet 7, also built there. The GKN North site had been sold in 2002 for £8m to the South East England Development Agency (an English regional development agency closed by the UK government in 2012) for the regeneration of East Cowes. This stalled with the financial crash in 2008 and is set never to achieve the site's full potential as a deep water Prime Tier 1 Marine Industrial Site.[7]
The docks at the Columbine Hangar have also been used by Red Funnel as berths for their Red Jet catamaran ferries when not in use; for example, Red Jet 6 was berthed at the Columbine while undergoing system tests, while Red Jet 3 was docked there while on sale awaiting a buyer during 2018.[8]
The Rocket Development Division was formed in 1956 and the Rocket Test site at Highdown started functioning exactly one year later. The division was headquartered at Yeovil. It was this division, in conjunction with the Royal Aircraft Establishment, that was responsible for the design, manufacture and static testing of the Black Knight Rocket, the first of which was successfully fired at Woomera, South Australia, on 7 September 1958.
Military canoes, assault boats and load carriers (World War II)
Designed by Fred Goatley# Marine designer Mark 2 Canoe– 1941–1942 (used on the Cockleshell Heroes "Frankton Raid") Mk 2** Canoe– 1943 ( used in Leros– various, incl. Sunbeam Raids ) 12-man Assault craft c. 1940–1942 8 ton load carrier. c. 1942–1943[14][15]
Electronics
The Electronics Division was formed in 1948. Its progress was rapid and the division also designed and manufactured such diverse specialist equipment as Analogue Computers, Control Simulators and a variety of Electronic Equipment and Electronic Test sets associated with Guided Weapons. When using strain gauges of the normal wire type in the dynamic testing of helicopter components, notably rotor blades, Saunders-Roe found that such a high proportion of the gauges were failing that development was considerably retarded. The Electronics Division was therefore asked to devise an improved gauge and, in collaboration with Messrs. Technograph Printed Circuits Ltd.,[16] produced the foil strain gauge.
Hydrofoil
R-103– a 17-ton hydrofoil for Royal Canadian Navy, known as "Bras d'Or". Built in 1956 by Saunders-Roe (Anglesey) Ltd. (This should not be confused with HMCS Bras d'Or, a 240 tonne hydrofoil patrol vessel, which was the result of the tests performed by the R-103.)
Illuminated signs
Early in aviation, it was difficult– if not impossible– to supply uninterrupted power in aircraft. Saunders-Roe solved this problem by putting an ionising gas (tritium; 3H) in small tubes. Tritium was discovered in 1934 by Lord Rutherford. The tubes ("Betalights") are made of borosilicate glass. The inside of the tubes is coated with a fluorescent powder, which glows as a result of the ionizing radiation of the tritium gas. Such a tube emits light for 15 years. Betalights were used to illuminate the flight instruments, exit signs and corridors of the aircraft produced by Saunders-Roe. When Saunders-Roe was acquired by Westland Helicopters production continued via Saunders-Roe Developments Ltd of North Hyde Road, Hayes, Middlesex (the former Fairey Aviation Head office). Betalight production was made independent under the name SRBT (Saunders-Roe Betalight Technology). A factory was established in Pembroke, Ontario, Canada, where tritium supplies are readily available. Today betalights are used in self luminous escape-route signs, under the product name Betalux.
In early 1953, Saunders-Roe at Anglesey completed the Mark 3 airborne lifeboat to be fitted underneath the Avro Shackleton maritime reconnaissance aircraft. This model was made entirely of aluminium, previous marks being made of timber. Parachuted at a rate of 20 feet per second into the rescue zone, the craft was powered by a Vincent motorcycles HRD T5 15hp engine; sails and a fishing kit were also provided. The Mark 3 measured 31 feet (9m) from bow to stern and 7 feet (2m) across the beam and held enough to supply 10 people with food and water for 14 days.[17]
Road vehicles
During World War II, Saunders-Roe opened a factory at Fryars in Llanfaes, Anglesey, converting and maintaining Catalina flying boats. In the late 1940s and 1950s the Beaumaris factory began making bus bodies under the names Saunders, SEAS (Saunders Engineering & Shipbuilding) and SARO. When AEC took over Crossley Motors, many of the design staff left and joined SARO. In pre-Atlantean days when Leyland began looking at low floor vehicles, the "Low Loader" (STF 90) bodied by SARO was similar in certain respects to the Crossley chassisless bus designs. Bodies were manufactured at Beaumaris for installing on "Leyland Royal Tiger" and "Leyland Tiger Cub" chassis; SARO bodied 250 RTs for London Transport between 1948 and 1950 (RT 1152–1401), which were almost indistinguishable from the standard Weymann/Park Royal products; and some double-deck buses for Liverpool Corporation. 620 prefabricated Rivalloy (the brand name comes from rivetted (aluminium) alloy) single deck buses components for local assembly were sold to Autobuses Modernos SA, Cuba which later became Omnibus Metropolitanos, S.A. Another large customer was Auckland Regional Transport in New Zealand who took the Rivalloy body on 90 Daimler Freeline chassis. In 1948 the only double deck bodies to be exported were 20 ordered by South African operator Durban Motor Transport which were mounted on AEC Regent Mark III chassis.[18] In the UK large numbers of SARO bodies were specified by the British Electric Traction group on Leyland Tiger Cub chassis, operators including Trent, East Midland, Ribble, Yorkshire Traction and the Northern General Group. An integral version of the body design powered by a Gardner 5HLW engine was bought by Maidstone & District.
The factory later passed to Cammell Laird who mainly used it for producing refuse-collection vehicles, but when Metro Cammell Weymann had a production backlog, they completed a batch of MCW-style double deck forward-entrance highbridge bodies on Leyland Titan PD3 for Brighton Corporation, these were numbered 31–5, registered LUF131-5F and delivered in June and July 1968, they were unusual as front engined half-cab buses built to be driver operated.[19]
Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961.
Westland Helicopters was a British aircraft manufacturer. Originally Westland Aircraft, the company focused on helicopters after the Second World War. It was amalgamated with several other British firms in 1960 and 1961.
The Bristol Proteus was the Bristol Engine Company's first mass-produced gas turbine engine design, a turboprop that delivered just over 4,000 hp (3,000 kW). The Proteus was a reverse-flow gas turbine. Because the second turbine drove no compressor stages, but only the propeller, this engine was classified as a free-turbine. It powered the Bristol Britannia airliner, small naval patrol craft, hovercraft and electrical generating sets. It was also used to power a land-speed record car, the Bluebird-Proteus CN7. After the merger of Bristol with Armstrong Siddeley the engine became the Bristol Siddeley Proteus, and later the Rolls-Royce Proteus. The Proteus was to have been superseded by the Bristol Orion which would have given a Britannia a 75% increase in power for cruising faster.
The Saunders-Roe SR.45 Princess was a British flying boat aircraft developed and built by Saunders-Roe at their Cowes facility on the Isle of Wight. It is the largest all-metal flying boat to have ever been constructed.
The Saunders-Roe SR.A/1 was a prototype flying boat fighter aircraft designed and built by British seaplane manufacturer Saunders-Roe. It was the first jet-propelled water-based aircraft in the world.
The Saunders Roe A.27 London was a British military biplane flying boat built by the Saunders Roe company. Only 31 were built, entering service with the Royal Air Force (RAF) in 1936. Although due for replacement by the outbreak of World War II, they saw some active service pending the introduction of the ultimately unsuccessful Lerwick.
British Hovercraft Corporation (BHC) was a British hovercraft manufacturer that designed and produced multiple types of vehicles for both commercial and civil purposes.
The Society of British Aerospace Companies was the UK's national trade association representing companies supplying civil air transport, aerospace defence, homeland security and space. As of October 2009 SBAC merged with the Defence Manufacturers Association and the Association of Police and Public Security Suppliers to form the ADS Group.
The Saunders-Roe SR.N1 was the first practical hovercraft. The concept has its origins in the work of British engineer and inventor Christopher Cockerell, who succeeded in convincing figures within the services and industry, including those within British manufacturer Saunders-Roe. Research was at one point supported by the Ministry of Defence; this was later provided by the National Research Development Corporation (NRDC), who had seen the potential posed by such a craft.
Spartan Aircraft Limited was a British aircraft manufacturer from 1930 to 1935. It was formed by reinvestment in Simmonds Aircraft which had suffered financially.
The Saunders Roe A.37 Shrimp was a 1930s British two-seat four-engined experimental flying boat built by Saunders-Roe Limited ("Saro") at Cowes.
FPT Industries was formed in July 1939 as Fireproof Tanks Ltd as a subsidiary of Airspeed Ltd at Portsmouth Airport in response to an Air Ministry requirement for the development and manufacture of self-sealing fuel tanks for the impending war with Germany.
The Saunders-Roe Duchess also known as the model P.131 was a British design for a large jet-powered flying boat envisaged by Saunders-Roe, based in Cowes on the Isle of Wight.
The SR.N2 was a hovercraft built by Westland and Saunders-Roe. It first flew in 1961. It weighed 27 tons and could carry 48 passengers. Although only one was built it is regarded as the prototype for commercial hovercraft, following on from the SR.N1 research craft. It was demonstrated on the Saint Lawrence River, Canada in 1962 and operated by P & A Campbell as a ferry crossing the Bristol Channel between Weston-super-Mare and Penarth in 1963. It was then fitted with deeper (4 ft) skirts to improve its performance in rough seas. Southdown Motor Services and Westland Aircraft ran the SR.N2 on the Solent between Eastney and Ryde in 1963/4, carrying 30,000 passengers. It was eventually broken up.
The Saunders-Roe SR.N5 was a medium-sized hovercraft which first flew in 1964. It has the distinction of being the first production-built hovercraft in the world.
The Saro P.531 is a British all-metal five-seat helicopter designed and built by Saunders-Roe Limited (Saro). The P.531 was a larger development of the two-seat Saro Skeeter to use turbine power and formed the basis of the military Westland Scout and Westland Wasp helicopters.
The Martin-Baker Mk.1 is a British ejection seat designed and built by Martin-Baker. Developed in the late 1940s it was the first in the line of production Martin-Baker seats for military aircraft. Ground and air testing of earlier designs resulted in the first successful test ejection of a company employee in July 1946. A seat type designed for the Saunders-Roe company was known as the Pre-Mk.1.
Llanfaes Friary was a Franciscan friary in the now vanished medieval town of Llanfaes, close to what is now Beaumaris, in south east Anglesey, Wales. It was founded around 1237 in memory of Joan, wife of Llywelyn ab Iorwerth. The Friary survived the depopulation of the town, but was dissolved in 1538 and most of the buildings dismantled soon afterwards. The land became an estate on which, in 1623, Rowland Whyte built a house which he called Friars. It became one of the many properties of the Bulkeley family, and was substantially rebuilt in 1866. By the 20th century the house and grounds were owned by James Hartley Burton. In 1939 they were requisitioned for wartime use, adapting and repairing flying boats, by Saunders-Roe, who continued after the war with a wide variety of light engineering activities. The industrial uses finally came to an end in the late 1990s. An archaeological dig on the site in 1991 identified substantial buried remains of the friary church and other monastic buildings. The site is a Scheduled monument.
S. E. Saunders Ltd, was a British marine and aero-engineering company based at East Cowes, Isle of Wight in the early 20th century.
Maurice Joseph Brennan BSC, MIMechE, FRAes was a British aerospace engineer. His career encompassed the design and development of flying boats before the Second World War to rocket powered fighters after. He had a significant role in Britain's first indigenous rocket project and in the development of practical hovercraft (SR.N1)
