T.Buttler - TSR.2's company: Hawker P.1129
27 сентября 1964г.: теоретически обладающий скоростью до 3М, штурмовик TSR.2 включал в себя ряд перспективных технологий, но был снят с эксплуатации в 1965 году.
And the winner is... Vickers-Armstrongs and English Electric had fielded a strong candidate for GOR.339, focusing on its capabilities as a weapons-system rather than merely an airframe. The sole flying example of the BAC TSR.2, XR219, made its first flight in September 1964 - and was cancelled in April 1965.
The colour scheme on this speculative artwork of the original P.1129 design with semicircular intakes, comprising uppersurface camouflage in Dark Sea Grey and Dark Green, with Anti-Flash White on the undersurfaces and low-visibility fuselage roundel is based on BAC Drawing 57900 of November 1964 for a proposed scheme for the first pre-production batch of TSR.2s.
The P.1129 could trace its roots back to the same company’s P.1121, a strike variant of its P.1103 supersonic fighter project to OR.329. A mock-up of the single-seat single-engined P.1121 was built at Kingston, where it is seen here. The P.1121 was developed into the twin-engined P.1125, which itself led to the larger two-seat P.1129.
All that remains of Hawker’s P.1129 project in terms of hardware is a 1/24th-scale display model of the penultimate development version kept in storage at Brooklands Museum in Surrey. Note the later larger intakes, which replaced the semicircular conical intakes with half-cones originally incorporated on the early P.1129 design.
By August 1958 the P.1129 had been redesigned, retaining the original design’s wings, tailplane and fin but with a slightly longer fuselage - 73ft 6in (22-4m) as opposed to the original 72ft 9in (22m) - and new swept rectangular intakes, as seen in this Hawker drawing labelled “P.1129 Development Supersonic Strike Aircraft”. It is this version of which a display model survives at Brooklands Museum.
Included in the January 1958 brochure was this schematic drawing showing the P.1129’s antennae installations. The aerials marked Violet Picture refer to the homing system fitted to RAF aircraft to locate aerial tankers, among other uses. The X-band sideways-looking aerials forward of the intakes were housed within apertures covered with dielectric material.
Although Hawker was unable to give a great deal of information in its January 1958 brochure about the various electronics, radio and radar systems proposed for the P.1129, for obvious security reasons, the brochure does provide this schematic detailing their locations within the airframe. The brochure goes into some detail regardng the navigation systems and equipment, but is understandably tight-lipped on the radar and fire-control systems.
The brochure does state, however, that the forward-looking radar would contribute to the navigation of the aircraft to some degree, and so provides a few details of the nose-mounted radar equipment. It revealed that this would be a development of Blue Parrot, itself an upgraded version of the AI.23 AIRPASS system devised for low-level operations and target detection, and later fitted to the Blackburn Buccaneer.
After a great deal of wrangling between the two competing parts of the Hawker Siddeley Group - Avro and Hawker - for GOR.339, a final iteration was drawn up incorporating Ferri intakes (with swept-forward lips, as on the Republic F-105), as seen in this artist’s impression. This final HSG submission was presented in a brochure produced by Avro at the end of 1958 - but it was too little too late.

The three-view general arrangement drawing of the P.1129 as presented in Hawker’s January 1958 brochure. At this stage the design incorporates the original semi-circular intakes with half-cones, and is seen here with a semi-recessed Red Beard nuclear bomb in its weapons bay. Note the optional wing tanks included on the plan view, in which a cumulative total of some 1,600gal (7,275lit) could be carried.
