FLIGHT, 20 June 1958 853 Military Aircraft of the World . . . Left, Breguet 1001 Taon Below, Dassault Mirage III INDIA Hindustan Fighter The only aircraft and engine production unit inIndia, Hindustan Aircraft is reported to be undertaking the design of a jet trainer and an advanced jet fighter under the present Indian five-yearplan. The designer of the fighter is said to be Kurt Tank. Hindustan HT-2 Production of a considerable batch of these basictrainers for the Indian Air Force and Navy has now been completed and the aircraft has been offered for export to South-East Asian countries.It is a low-wing, tandem two-seat, all-metal trainer powered by a Black- burn Cirrus Major III giving 155 h.p. Span, 35ft 2in; gross weight, 2,240 Ib; cruising speed, 115 m.p.h.;endurance 3.5 hr. FRANCE FIGHTERS AND FIGHTER BOMBERS Breguet 1001 Taon Designed for the NATO lightweight strike fightercompetition, the Taon is powered by a Bristol Orpheus BOr.3. A great deal of wind-tunnel work, some of it in America, went to the develop-ment of the aircraft and area rule is fully applied. Extensive use is also made of bonding and honeycomb sandwich in the structure. On April 25the Taon, piloted by Bernard Witt, set up a new 1,000 km closed-circuit speed record at 539.85 kt. The Taon, which made its first flight last summer, was preceded bythe Br.1100, powered by two Turbomeca Gabizos and prepared for a French Air Force specification. It is likely that the Taon, with the morepowerful Orpheus BOr.12, will become the standard NATO lightweight strike fighter after 1961. Recent modifications include extra area-rulebulges about the wing leading-edge. The Taon at present has a very thin wing of 158 sq ft area (when theBOr.12 is fitted, area will be increased to 210 sq ft) carrying wide span, narrow chord flaps and wide-chord, narrow-span ailerons assisted byknife-edge spoilers ahead of the flaps. This ensures a rate of roll of 200 deg/sec at Mach 1 at sea level. The Jacottet controls are fullypowered and a Jacottet feel unit is incorporated. A yaw-damper is also included. Armament consists of four 0.5in machine guns under theintakes, a shelf ahead of these preventing ingress of gases. A full range of stores including missiles is carried under the wings. Span, 22ft 3\in; length, 36ft lOfirt; empty weight, 5,700 Ib; max. grossweight, 12,500 Ib; max. speed, Mach 1 plus in a dive, Mach 0.97 level; tactical radius, about 200 miles. Dassault SMB2 Super Mystere Production of some 370 SMB2s hasbeen under way now for about a year, although recent military budget restrictions indicate that the total number may be reduced by about 80.The first production machine flew on February 26 last year. It was the first production aircraft in Europe capable of exceeding Mach 1 in levelflight. Power is provided by a SNECMA Atar 101G with afterburner, giving 9,900 lb static thrust, though the last machines will have theAtar 9 of 13,230 lb thrust. Armament consists of two 30 mm DEFA cannon and a retractableMatra pack of 35 folding-fin, air-to-air rockets. The latter may be replaced by a fuel tank. Some 2,000 lb of underwing stores may also becarried. Integrally stiffened skin panels and single-piece milled wing- spars are incorporated. The SMB2 was reported by a German pilot tobe level-supersonic above 25,000ft. Controls include fully powered ailerons and slab tailplane, yaw stabilizer and possibly also an auto-Machtailplane control. Radar-ranging and a miniaturized A.I. radar for the SMB2 have been produced by the electronics division of Dassault. Span, 34ft 5fin; length, 46ft lin; weight empty, 15,400 Ib; grossweight, clean, 19,840 Ib; max. gross weight, 22,046 Ib; max. speed at 36,000/r, 743 m.p.h., Mach 1.125; initial rate of climb, 17,500/r/mi'n;ceiling, 55,750/t. Dassault Etendard IV Marine The prototype made its first flight onMay 21 and a pre-production batch is under way. The type is intended for operation from the Clemenceau carriers and can exceed Mach 1 inlevel flight. A SNECMA Atar 8 of 9,700 lb thrust is fitted and the undercarriage has a stroke of 16in. Low-pressure tyres may also be fittedfor operation from grass fields. The low-set swept wing carries a drooping leading edge and high-lift flaps. The extremities of the wing only foldand the ailerons are fitted between the folding hinge and the flaps. Horizontal control is by slab tailplane. The airframe is stated to bearea-ruled. No details of dimensions, armament or performance have been released, though it is known that it is larger than the Etendard IV.Carrier-landing speed is reported to be 140 m.p.h. Dassault Etendard VI An unpressurized, Bristol Orpheus-poweredlight fighter prepared for the NATO lightweight strike fighter competi- tion, in which it was not successful. Armament was four 0.5in machineguns and underwing stores. Main development effort is probably now concentrated on the IV Marine version of the Etendard.Span, 31/r 6in; length, 41ft 2\in; empty weight, 7,495 Ib; gross weight, 14,330 Ib; max. Mach no. at sea level, 1.0. Dassault Mirage III Intensive development of this intercepter is goingahead, the III-001 now carrying adjustable shock-cones in the lateral intakes and a conical camber on the leading edge of the delta wing; Below, Dassault SMB2 Super Mystere Below, Dassault Etendard VI
