The Vickers Warwick was a multi-purpose British aircraft used during the Second World War. Built by Vickers-Armstrongs, the Warwick was used by the Royal Air Force (RAF) as a transport, air-sea rescue and maritime reconnaissance platform and by the civilian British Overseas Airways Corporation (BOAC).

Design and development

The Warwick was designed to Air Ministry specification B.1/35 for a two-engined heavy (by the standards of the day) bomber in parallel with the Wellington. The prototype orders were cancelled in 1936 when it was decided to standardise on four-engined bombers. Vickers-Armstrongs completed two prototypes, one with Rolls-Royce Vulture liquid-cooled "X" engines - withdrawn due to engine cooling difficulties - and one with the air-cooled Pratt & Whitney Double Wasp.

The Warwick used Barnes Wallis' geodetic construction pioneered in the Wellesley and Wellington. In this system, a network of intersecting structural members made from duralumin were covered by wired-on fabric. The load was distributed amongst the structure, providing great redundancy in the event of damage, at the expense of complexity of construction. A total of 219 Warwick Mark Is were built, the last 95 with 2,000 hp (1,500 kW) R-2800-47 engines.

Operational history

The Warwick was ordered by RAF Coastal Command for anti-submarine reconnaissance. From 1943 Warwicks were loaded with the 1,700 lb (770 kg) Mk IA lifeboat and used for air-sea rescue. The lifeboat, designed by yachtsman Uffa Fox, laden with supplies and powered by two 4 hp (3 kW) motors, was aimed with a bombsight near to ditched air crew and dropped on parachutes into the sea from an altitude of about 700 ft (320 m). Warwicks were credited with rescuing crews from Halifaxes, Lancasters, Wellingtons and Fortresses and during the Arnhem landings from Hamilcar gliders.

Warwick Mark I

• Warwick B Mk I — original production bomber, of 150 ordered, only 16 aircraft were built. They were used for a variety of tests.
• Warwick C Mk I or Vickers Type 456 — transport version for BOAC, for use on its Mediterranean and North African routes.
• Warwick B/ASR Mk I — 40 aircraft converted from the Warwick B.Mk I bomber. The Warwick ASRs were used as air/sea rescue aircraft. They could carry two sets of Lindholme lifesaving equipment.
• Warwick ASR (Stage A) — Ten aircraft converted from the Warwick B Mk 1 bomber. The Warwick ASR (Stage A) was used for air/sea rescue. They could carry one airborne lifeboat and two sets of Lindholme lifesaving equipment.
• Warwick ASR (Stage B) — 20 aircraft converted from the Warwick B Mk 1 bomber. The Warwick ASR (Stage B) were air/sea rescue aircraft, carrying the same equipment as the Warwick ASRs and ASR (Stage As).
• Warwick ASR Mk I or Type 462 was an air/sea rescue version, it could carry an airborne lifeboat. The aircraft was powered by two 1,850 hp (1380 kW) Pratt & Whitney Double Wasp R-2800-S1A4G radial piston engines. 205 built.

Warwick Mark II

• Warwick B Mk II or Vickers Type 413 — bomber prototype, only one machine was ever built, converted from a Warwick B Mk I.
• Warwick GR Mk II or Vickers Type 469 — anti-submarine, general reconnaissance version. It was equipped to carry torpedoes and bombs. It was powered two 2,500 hp (1,864 kW) Bristol Centaurus VI radial piston engines; 118 built.
• Warwick GR Mk II Met — meteorological reconnaissance version of the Warwick GR Mk II; 14 built.

Warwick Mark III

• Warwick C Mk III or Vickers 'Type 460 — transport version. It had a pannier-like extension below the central fuselage, the normal loaded weight being raised to 45,000 lb (20,400 kg). It could carry 24 equipped troops or eight to ten passengers in the VIP version. No armament was carried; 100 built.

Warwick Mark IV

• Warwick ASR Mk VI or Vickers Type 485 — final air/sea rescue version. The aircraft was powered by two Pratt & Whitney Double Wasp R-2800-2SBG radial piston engines. 94 built.

Warwick Mark V

• Warwick GR Mk V or Vickers Type 474 — anti-submarine, general reconnaissance aircraft. It was powered by two Bristol Centaurus VII radial piston engines, armed with 7 machine guns and could carry 6,000 lb (2,700 kg) of bombs, mines or depth-charges. A Leigh light was fitted ventrally. It arrived too late to see service. 210 built.
