FLIGHT, 8 July 1960 MILITARY AIRCRAFT OF THE WORLD . . . France «r Breguet 1150 Atlantic Breguet 1050 Alize More than 45 of the 85 Alizes ordered tor theFrench and Indian navies have now been delivered and the production rate is four a month. Powered by a Rolls-Royce Dart Mk 22 turbopropof 1,975 s.h.p. driving a Rotol four-blade propeller, the Alize carries 462gal of fuel in the fuselage and wings, a crew of three, a retractableradar beneath the rear fuselage, chutes for flares or sonobuoys in the rear fuselage and further sonobuoys in the forward sections of thefairings housing the main undercarriage legs. Offensive weapons include a torpedo or three 3531b depth charges in the fuselage weapon bay, twofurther depth charges on racks beneath the inner wings and six Sin rockets or two Nord SS.ll missiles under the outer wings. The wingsfold and an arrester and catapult hooks are fitted. Span, 51ft 2m; length, 45ft 6in; equipped weight, 12,566!b; grossweight, 18,078!b; max sea level speed, 285 m.p.h.; patrol speed, 150-230 m.p.h.; service ceiling, 20,000/r; normal endurance, 5hr 20mm; take-offrun, 1,890/t; landing run, 1,540ft; initial rate of climb, 1,380/r/mm. Breguet 941 Integral The French government has placed an orderfor a prototype of this STOL deflected slipstream transport which is to fly in the middle of next year. With a cruising speed of about 250m.p.h. and a gross weight of about 20 tonnes the Integral will carry 40-44 passengers and be able to operate commercially from fields 650to 1,300ft long. Its civil prospects are excellent and a pressurized version is planned, but it also has obvious military potentialities. Exceedingly high lift for very short take-off and landing is obtainedby covering the whole wing in the slipstream of four large propellers driven from a transverse shaft which four 1,250 s.h.p. Turbomeca TurmoHID engines drive through free turbines. The failure of one engine would therefore simply reduce the power supplied to the transverseshaft. Each pair of propellers rotates in opposite directions and the pitch of the outer propellers can be varied differentially to increaselateral control and partially reversed to increase drag before and during landing. For take-off and landing the slipstream is deflected throughalmost 90° by full-span two-section flaps, the outer rear portions of which also act as ailerons. The undercarriage is to be of the MessierJockey type and clamshell doors and a retractable ramp will allow rear loading. Span, 76ft \in; length, 70ft 6m; gross weight, 44,000/fc; useful load,19,800/fc; cruising speed, 250 m.p.h.; take-off run, 330-650/t; landing run, 330/t. Breguet 1150 Atlantic On December 31 the NATO armament com-mittee decided to select the Breguet 1150 Atlantic as the standard NATO maritime patrol and ASW aircraft. The accompanying illus-tration is the first to show accurately the configuration of the Atlantic which is to be powered by two Rolls-Royce Tyne 20s each rated at6,000 e.h.p. and driving de Havilland four-blade propellers. The prototype is to fly in November next year and the Atlantic should becleared for initial operations in less than three years. Production tooling will be prepared straight away because France, Germany, Holland andBelgium have already placed firm orders; and these countries and the US under MWDP have already contributed funds. A directing com-mittee representing France, Holland, Germany and Belgium is already at work co-ordinating the construction of the aircraft and a technicalconsulting committee open to all NATO countries has been established so that all interested parties can monitor development. Great Britainand Canada are represented, although they have not yet stated any intention of participating. Breguet produced the original design study for the Atlantic whichwon a competition from 25 other companies representing eight countries. Breguet are therefore co-ordinating the whole project and constructingand testing the prototype. After this, the development of the central wing section and naceiles will be taken over by Fokker. Dornier willtake charge of the rear fuselage and tail, Sud-Aviation and a Belgian group called ABAP will take over the outer wings. These companieswill then produce their components and ship them to Breguet for final assembly and test. Production might well reach 400 aircraft. The Atlantic has a "double bubble," pressurized fuselage with asearch radar mounted in the nose and a weapons bay in the lower bubble beneath the low-mid-set wing. Very extensive and advanced Dassault Mirage NIC Breguet 1050 Alixe Breguet 941 Integral Dassault Mirage IV electronic equipment, partly from the USA and Great Britain, will beincorporated, as well as bulged visual-search windows in the rear fuselage. It is intended that the Atlantic should have an endurance inexcess of 20 hours and that, for best economy, it will cruise at high altitude to and from its search area at 373 m.p.h. It will also be capableof flying at very low speeds. Crew complement will be twelve, not all of them on duty at one time. Span, 124/t; length, 89/r 5in; wing area, 1,295 sq ft; gross weight,85,9801b; cruising speed, 373 m.p.h. Dassault Mirage IV Now designated as the manned delivery systemfor the French nuclear strike force, the Mirage IV is aerodynamically a scaled-up Mirage III with two crew members in tandem and poweredby two SNECMA Atar 9s with afterburners. Production aircraft will weigh 105,8001b, a larger version originally proposed having beenabandoned because of a reappraisal of the mission profile. Autonomous strike radius, flying to target at supersonic speed and retiring at M0.9,would be 800 miles, but this will be extended by flight refuelling from other Mirage IVs to between 1,200 and 1,800 miles. The prototype hasnow exceeded M2, having first flown on June 17 last year. A pre-produc- tion batch of ten will be powered by Atar 9Js. In 1964 and 1965 40 moreMirage IVs will be delivered. The prototype has now also flown with a shape indicating dimensions of a nuclear weapon recessed beneath thefuselage. An elaborate navigation and bombing radar is being prepared by CSF and anti-missile RCM will be used for defence. The Mirage IVhas a new AC electrical system and uses a special high-temperature hydraulic fluid developed by ONERA. Dassault Mirage III Plans are in hand for the production of some470 Mirages by 1965 and the type will become the standard French multi-purpose combat aircraft. Ten pre-production aircraft have forsome time been under evaluation and the first production machine should be completed in September. The Mirage IIIC, the first pro-duction type, was fully described in Flight for April 22. It is powered by a SNECMA Atar 9C giving 9,3701b without and 14,1001b thrustwith afterburner. A SEPR 841 liquid rocket pack can be installed in a fuselage bay for the intercepter role or replaced by a 90gaI fuel tank.Fixed armament is a pack of two 30mm guns replaceable by a rocket Dassault Mirage MB
