RAF Topcliffe ĭisbanded on 5 June 1953 the four Neptune aircraft of Vanguard Flight became the re-formed 1453 (Early Warning) Flight at RAF Topcliffe in Yorkshire. On 1 November 1952, four Lockheed Neptune MR Mk.1 aircraft ( WX547, WX499, WX500 and WX501) formed the complement of Vanguard Flight of Fighter Command at RAF Kinloss, to research and develop tactics for use by Airborne Early Warning aircraft. The Helmore Turbinlite was also evaluated as an anti-submarine attack searchlight, but the Leigh Light was found to be superior. (Airborne interception) radar was gained. Results of the combined operations were not spectacular, (only one confirmed kill with 31 aircraft lost), but valuable experience in the use of the A.I. 532 Squadron RAF (532 Sqn) on 8 September 1942 (not on 2 September due to administrative reasons) and the flight officially disbanded as late as 31 January 1943. Thirty-nine DB-7A's (Havoc II) were also converted to use the Turbinlite searchlights and these also saw service with the Turbinlite flights and the squadrons formed from the flights from 2 September 1942, 1453 Flt becoming No.
486 Squadron RNZAF, also housed, like 1453 Flt, at RAF Wittering These aircraft were to operate in conjunction with Hawker Hurricane nightfighters, illuminating the targets after tracking them with the radar, for the Hurricane fighters to despatch.ġ453 (Turbinlite) Flight was one of the flights, formed on 10 July 1941, especially to use the Turbinlite Havoc operating in conjunction with Hawker Hurricanes of No. Thirty-one of the DB-7's (Havoc I) were converted to carry the 2,700 million candela (2.7Gcd) Helmore Turbinlite searchlight in the nose, as well as Airborne Interception Mk.IV (A.I. With relatively few aircraft available and the good performance of the DB-7/A, named Havoc in UK service, made them suitable for use as intruders and night-fighters. History 1453 Flt and the Turbinlite Havocs Īfter the fall of France in 1940, outstanding contracts for Douglas DB-7 & DB-7A medium bomber aircraft were appropriated by the British Purchasing Commission.
In the 1950s the flight was briefly resurrected as an early warning flight and during the 1980s it was employed as a ground attack and air defence unit on the Falkland Islands. The following will describe the model, the selected experiments, and the results of the comparison of predicted with observed tracer concentrations.1453 (Turbinlite) Flight Royal Air Force was first formed in 1941 as a night-fighter unit at RAF Wittering, equipped with Douglas Turbinlite Havoc aircraft. The model used for these simulations was the Lawrence Livermore National Laboratory (LLNL) three-dimensional, diagnostic MATHEW/ADPIC atmospheric dispersion model for complex terrain and flow conditions.
