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 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.
The A.27 London was designed in response to the Air Ministry Specification R.24/31 [1] [2] issued for a "General Purpose Open Sea Patrol Flying Boat" and was based on the Saro A.7 Severn. The London and its contemporary, the Supermarine Stranraer, were the last multi-engine, biplane flying-boats to see service with the RAF. [1] [2] The design utilized an all-metal corrugated hull and fabric-covered wing and tail surfaces, with two Bristol Pegasus II radial engines, mounted on the upper wing to keep them clear of spray while taking off and landing.
The first prototype first flew in March 1934 and then went on to serve until 1936 with 209 and 210 Squadrons RAF at RAF Felixstowe and Gibraltar respectively.
The first deliveries of production aircraft began in March 1936 with Pegasus III engines, and from the eleventh aircraft onwards the Pegasus X engine was fitted instead and the aircraft's designation changed to London Mk.II. Earlier Londons were retrofitted with the Pegasus X and were also given the "Mk.II" designation.
The London Mk.II model equipped 201 Squadron RAF at RAF Calshot beginning in 1936, replacing Supermarine Southamptons. Others later were delivered in October 1936 to 204 Squadron RAF at RAF Mount Batten, Plymouth, also replacing Southamptons. More were delivered to the same squadron in 1937 to replace Blackburn Perths, and to 202 Squadron RAF at Kalafrana, Malta, replacing Supermarine Scapas, and 228 Squadron RAF at Pembroke Dock.
In 1937–1938 204 Squadron RAF used five Londons equipped with auxiliary external fuel tanks for a long-distance training flight to Australia to celebrate the 150th anniversary of the founding of the Colony at Sydney, New South Wales. In this configuration, they had a range of 2,600 miles (4,180 km).
At the outbreak of World War II in September 1939, Londons equipped 201 Squadron RAF, which was by now stationed at Sullom Voe in Shetland, and 202 Squadron RAF at Gibraltar, as well as 240 Squadron RAF at Invergordon, which had re-equipped with Londons in July 1939. These aircraft carried out active patrols over the North Sea and the Mediterranean. Some were fitted with a dorsal fuel tank to increase operational radius. Armament in the form of bombs, depth charges, and naval mines up to a total weight of 2,000 lb (907 kg) could be carried beneath the lower wings.
Gradually, the Londons' duties were assumed by newer aircraft such as the Lockheed Hudson, while squadrons flying Atlantic and Mediterranean patrols were re-equipped with Short Sunderlands. All were withdrawn from front-line duties by the middle of 1941.

The Fairey Barracuda was a British carrier-borne torpedo and dive bomber designed by Fairey Aviation. It was the first aircraft of this type operated by the Royal Navy's Fleet Air Arm (FAA) to be fabricated entirely from metal.
The Fairey Seafox was a 1930s British reconnaissance floatplane designed and built by Fairey for the Fleet Air Arm. It was designed to be catapulted from the deck of a light cruiser and served in the Second World War. Sixty-six were built, with two finished without floats and used as landplanes.
The Supermarine Walrus was a British single-engine amphibious biplane reconnaissance aircraft designed by R. J. Mitchell and manufactured by Supermarine at Woolston, Southampton.
The Saunders-Roe A.36 Lerwick was a British flying boat built by Saunders-Roe Limited (Saro). It was intended to be used with the Short Sunderland in Royal Air Force Coastal Command but it was a flawed design and only a small number were built. They had a poor service record and a high accident rate; of 21 aircraft, 10 were lost to accidents and one for an unknown reason.
The Supermarine Stranraer is a flying boat designed and built by the British Supermarine Aviation Works company at Woolston, Southampton. It was developed during the 1930s on behalf of its principal operator, the Royal Air Force (RAF). It was the RAF's last and fastest biplane flying boat.
The Vickers Vildebeest and the similar Vickers Vincent were two very large two- to three-seat single-engined British biplanes designed and built by Vickers and used as light bombers, torpedo bombers and in army cooperation roles. First flown in 1928, it remained in service at the start of the Second World War, with the last Vildebeests flying against Japanese forces over Singapore and Java in 1942.
The Saro A17 Cutty Sark was a British amphibious aircraft from the period between World War I and World War II, built by the British firm Saunders-Roe. The aircraft was named after the ship Cutty Sark, rather than the garment or the fictional witch.
The Gloster Gauntlet was a single-seat biplane fighter designed and produced by the British aeroplane manufacturer Gloster Aircraft in the 1930s. It was the last fighter to be operated by the Royal Air Force (RAF) to have an open cockpit, and also the penultimate biplane fighter in its service.
The Supermarine Sea Otter was an amphibious aircraft designed and built by the British aircraft manufacturer Supermarine. It was the final biplane flying boat to be designed by Supermarine; it was also the last biplane to enter service with both the Royal Navy and the Royal Air Force (RAF).
The Supermarine Southampton was a flying boat of the interwar period designed and produced by the British aircraft manufacturer Supermarine. It was one of the most successful flying boats of the era.
The Supermarine Scapa was a British general reconnaissance flying boat built by Supermarine that was used by the Royal Air Force between 1935 and 1939. It was developed from the Southampton and formed the basis of the later Stranraer flying boat.
The Westland Wallace was a British two-seat, general-purpose biplane of the Royal Air Force, developed by Westland as a follow-on to their successful Wapiti. As the last of the interwar general purpose biplanes, it was used by a number of frontline and Auxiliary Air Force Squadrons. Although the pace of aeronautical development caused its rapid replacement in frontline service, its useful life was extended into the Second World War with many being converted into target tugs and wireless trainers. In 1933 a Westland Wallace became the first aircraft to fly over Everest, as part of the Houston-Mount Everest Flight Expedition.
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.
The Percival Q.6 was a 1930s British communications aircraft built by Percival Aircraft Limited at Luton.

It was a twin-engine, low-wing monoplane with a tailwheel undercarriage.
The Handley Page H.P.54 Harrow was a heavy bomber designed and produced by the British aircraft manufacturer Handley Page. It was operated by the Royal Air Force (RAF) and saw use during the Second World War, although it was quickly overshadowed as a bomber by larger and more capable alternatives.
The Blackburn Perth was a British flying boat which was in service during the interwar period. It was essentially an upgraded Iris, and hence the largest flying-boat to serve with the Royal Air Force at the time.
The Saro A.21 Windhover was a British amphibious aircraft from the period between World War I and World War II, constructed by Saunders-Roe, or Saro. It was originally advertised as the A.19 Thermopylae after the famous clipper ship, being an enlarged version of the Saro Cutty Sark.
The Saro Cloud was a British passenger amphibian flying boat designed and built by Saunders-Roe as the A.19. It was later produced as the A.29 for the Royal Air Force for pilot and navigator training.
The Saunders A.14 was a test aircraft for Saunders' new metal hull construction method, being a Supermarine Southampton fitted with the Saunders' fuselage. The methods tested worked well enough to be used in SARO flying boat production from 1928 to 1938.
The Saunders Severn was a three-engined biplane flying boat intended for maritime patrol duties. It performed well but was fragile and unreliable. Only one was built.
