Si.II..-* I /"CAPABLE of operating from any shel- ve tered stretch of water, the S.R./A1 can be utilised not only as a fighter, but with bombs or rocket projectiles. Two Metropolitan-Vickers Beryl turbo jets are mounted side by sidt, ;n the hull and are fed by a single broad air intake located in the bow. The hull has closely spaced frames and relatively light stringers and the main step is of faired vee form. A single main spar is used for the wing, provided with dive brakes and dive-recovery flaps. Forward is the pressurised cockpit, with ejector seat, and the four 20-mm. guns. The maximum speed is at least 500 m.p.h. Span, 4Gft; length, 50ft; gross weight, 16,255 lb;initial rate of climb over +,000ft/min. WesttaiMi Wyvsrn T.F.2 Britain'' s Aircraft - Military Types * iciters-Armstrongs %ar»it» Per«*ival Prentice IN production for the Royai Air r'orce.Royal Indian Air Force and Argentine Air Force, the Prentice basic trainer is dis- played at Farnborough in two forms—the T.l, with D.H. Gipsy Queen 31 engine, and the T.2, with Gipsy Queen 51. Particulars quoted below are for the first-named variant. Of robust metal construction, the current Prentices have a very roomy cabin for an instructor and two students. The forward position of the front, side-by- side seats, in conjunction with the low placing of the engine, allows an unusually wide field of view. Span, 46ft; length, Sift 6%in; gross weight(aerobatic), 4,000 lb; gross weight (non-aerobatic), 4,200 lb; max. speed, 148 m.p.h. at sea-level. Scottish Aviation A.4/45 MILITARY forerunner of the Frest-wick Pioneer light transport, des-cribed elsewhere, the A.4/45 is a very robust high-wing monoplane with high- lift arrangements of great efficiency. Short Sturgreon first instance asrecon naissance-DESIGNED in the a carrier-borne reconnaissance bomber, the Sturgeon (two Merlin) is now in production for the Royal Navy as a target-towing and target-simulating air- craft, under the designation Sturgeon T.T.2. Notwithstanding the specially enlarged nose section and the provision of a "turret" for the observer, this version has a high performance and cruises with a 16-ft winged target at 289 m.p.h. Although the span is about 60ft, careful design has enabled the wings to be folded, for stowage aboard an aircraft carrier, to a width of only 20ft. Span, 59ft llin; length, 44ft lOin; grots weight,21,700 lb; max. speed, 402 m.p.h. at 19,000ft; service ceiling, 35,700ft; bomb load, 1 x 1,000 lb, or depthcharges. Vickers-Armstrongni Valetta A NUMBER of units of R.A.F. Trans-port Command are in process of being re-equipped with the Valetta C.I military transport (two Hercules 230), a development of the civil Viking. The differences between the Valetta and Viking are of greater extent than is generally appreciated. In place of the normal pas- senger entrance there is a large double door measuring 5ft lOin in mean height and 8ft 6in in width, and permitting the loading of trucks, field guns, etc. The floor has been specially strengthened to recrive these concentrated loads. Span, «9ft Sin; length, 65ft 2in; gross weight,30,500 1b; max. speed, 294 m.p.h. at 3,500ft. THOUGH differing appreciably inappearance, the Varsity T.I crew trainer, now in production for the R.A.F., is in all essentials a straightforward development of the Valetta military trans- port. It is primarily intended for day and night training in air navigation, bomb aiming, piloting, and radio-radar tech- nique, and to these ends is provided with the most up-to-date equipment. In order to accommodate the nosewheel, the fuse- lage is somewhat longer than that of the Valetta; a more obvious addition is the underslung structure, containing prone positions for the bomb-aimer and pupil. Span, 94ft llin; length, 67ft ftin; gross wing area,970 sq ft. Vickers-Supermarin© Spitfire and Neafire THE newest members of the historicSpitfire-Seafire family are the Spitfire F.24 and Seafire F.R.47. In each case the fuselage is basically similar, but that of the Seafire incorporates an arrester hook and fittings for rocket-assisted take-off. Power- folding wings are now standar 1 on the Sea- fire 47. The engine is a Rolls-Royce Griffon 87 and the armament four 20-mm. guns. Three 500-lb bombs, or various R.P. loads, can be carried, and for extreme range three auxiliary tanks are alternative
