In 2018, the RAF's vision of a future constellation of imagery satellites was initiated through the launch of the Carbonite-2 technology demonstrator. The 100 kg Carbonite-2 uses commercial off-the-shelf (COTS) components to deliver high-quality imagery and 3D video footage from space. The Royal Air Force celebrated its 100th anniversary on 1 April 2018. It marked

The unit was short lived with this identity and after two months it lost the Tactical from the title. On the 30 December 1940, the unit disbanded but immediately reformed, redesignating as the Coastal Command Development Unit . For the initial radars to be effective, operational techniques and skilled operatives were required. The Coastal Command Development Unit undertook service trials of all radar equipment such as ASV (air-to-surface-vessel) radar for RAF Coastal Command operations . Although it had its own aircraft, it also used flying boats from RAF Pembroke Dock ,
534-697: A detachment in Brunei , to support British forces stationed there to deter further aggression by Malayan communist guerrillas. The type also saw combat service with the RAF during the Cyprus Emergency and the Aden Emergency , in addition to other operations. In December 1971, the last of the RAF's Sycamores were officially retired; this had been due to critical parts having reached the end of their fatigue life. However 32 Squadron continued to operate two Sycamores until August 1972. Fifty Sycamores were delivered to

6497-487: The physical defence and maintenance of sovereignty of the British Overseas Territories and enable the UK to conduct expeditionary military operations . Although command and oversight of the bases is provided by Strategic Command , the airfield elements are known as RAF stations. Four RAF squadrons are based overseas. No. 17 Test and Evaluation Squadron is based at Edwards Air Force Base , California, in
6586-403: The pilot was a swivelling seat for a medical attendant. The blades of the three-bladed main rotor were attached to the rotor head with lightweight interleaving steel plates while tie-rods carried the centrifugal tension loads. The blade levers were connected using ball joints to the arms of a control spider, the cone of which was actuated up and down by the collective pitch lever which changed
6675-401: The pitch of all the blades; an irreversible mechanism was used to prevent blade loads being transferred back to the control stick. The blades were supported when stationary or turning slowly by droop stops, which maintained a minimum clearance between the blade tips and the tailboom even in high winds; these stops were withdrawn above 100 rpm so that full freedom of movement for effective flight
6764-419: The same aircraft type. Some schools operate with only one squadron, and have an overall training throughput which is relatively small; some, like No. 3 Flying Training School , have responsibility for all Elementary Flying Training (EFT) in the RAF, and all RAF aircrew will pass through its squadrons when they start their flying careers. No. 2 Flying Training School and No. 6 Flying Training School do not have
6853-471: The staffing of hospitals, testing units and vaccination centres. Under Operation Broadshare , the RAF has also been involved with COVID-19 relief operations overseas, repatriating stranded nationals and delivering medical supplies and vaccines to British Overseas Territories and military installations. The UK's 20-year long operations in Afghanistan came to an end in August 2021, seeing the largest airlift since
6942-480: The type was often used as a transport for both passengers and cargo alike. In RAF service, the Sycamore was normally used in the search and rescue and casualty evacuation roles. The type proved the value of rotorcraft to easily traverse inhospitable or otherwise inaccessible terrain; the Sycamore made valuable contributions to British military activities during the Malayan Emergency , the Cyprus Emergency , and
7031-421: The usual arrangement of the era of using externally-mounted "pods" for carrying patients. To provide the extra width necessary in the cabin, detachable Perspex blisters were fitted on each side of the cabin. The stretcher racks could be folded into the sides of the cabin, providing room for up to three sitting casualties instead; an electrical supply outlet was available for connecting electric blankets . Next to
7120-555: The war was the strategic bombing campaign against Germany by Bomber Command. While RAF bombing of Germany began almost immediately upon the outbreak of war at first it was ineffectual; it was only later, particularly under the leadership of Air Chief Marshal Harris , that these attacks became increasingly devastating, from early 1943 onward, as new technology and greater numbers of superior aircraft became available. The RAF adopted night-time area bombing on German cities such as Hamburg and Dresden . Night time area bombing constituted
7209-550: Was achieved by twisting the pitch lever. The Sycamore had a relatively high rotor speed for the era, which was claimed to give a smoother ride and be safer in the event of engine failure. From 1952 to 1955 the Sycamore was used for various trials by the Air-Sea Warfare Development Unit RAF which was stationed at RAF St. Mawgan . In April 1953, the Sycamore HR14 entered service with No. 275 Squadron of
7298-520: Was also used in a variety of civilian roles. A single example was used during the construction of the M1 motorway between London and Leeds ; the type provided support in various roles, including to perform aerial surveying, communication across various sites, the carriage of both personnel and equipment, and the mitigation of flooding on the project. Sycamores operated by Australian National Airways were routinely available for charter, performing tasks such as
7387-641: Was continued by the V bombers into the 1980s and until 1998 by the Panavia Tornado GR1 . For much of the Cold War the primary role of the RAF was the defence of Western Europe against potential attack by the Soviet Union , with many squadrons based in West Germany . The main RAF bases in RAF(G) were RAF Brüggen , RAF Gutersloh , RAF Laarbruch and RAF Wildenrath – the only air defence base in RAF(G). With
7476-418: Was drawn through a forward-facing grill to cool the gearbox before passing through the engine cowling and leaving the fuselage. The engine power was controlled by the collective pitch lever. In order to maintain the rotor speed at its required setting fuel to the engine had to be automatically varied as the rotor pitch setting commanded by the pilot changed the load on the engine; fine adjustment of engine power
7565-459: Was granted for the Sycamore, the first such to be granted to a British helicopter. During the flight test programme, Bristol's key development pilots for the Type 171 included Charles "Sox" Hosegood and Col. Robert "Bob" Smith. In 1951, a Bristol-owned Sycamore Mk.2 was used during a series of deck landing trials performed on board the Royal Navy aircraft carrier HMS Triumph . An improved model of
7654-410: Was possible. The Sycamore was powered by a single Alvis Leonides piston engine of 550 hp (410 kW). The engine was mounted below and to the rear of the main rotor on a flexible mounting to reduce vibrations transmitted to the helicopter structure. It was isolated in a fireproof enclosure which was fitted with fire detection and extinguishing equipment to meet certification requirements. Air
7743-556: Was set up in Ceylon (Sri Lanka) to conduct trials of equipment supplied to South East Asia Command , lasting around twelve months. The unit moved to RAF Ballykelly in May 1948 and along with the trials work it also provided aircrew training for operational squadrons. It moved to RAF St Mawgan during May 1951, and remained there for the next seven years, before returning to RAF Ballykelly in September 1958. While at RAF St Mawgan it operated
7832-623: Was used by the RAF Central Flying School for pilot training purposes. In June 1953, a Sycamore towing a large RAF Ensign led a flypast by 640 British and Commonwealth aircraft at the Coronation Review of the RAF . The Sycamore was heavily used during the Malayan Emergency (1948–1960), typically deploying Army foot patrols into the jungle. Numerous Sycamores were transferred to the Far East Air Force to participate in
7921-408: Was usually fitted with three folding canvas seats as well as a single rotating seat besides the pilot. In addition to the passenger cabin, it had a separate luggage compartment. A specialised air ambulance model of the Sycamore was developed during the early 1950s. In this configuration, up to two patients were carried inside the cabin on stretchers stacked one above the other; this was different to
