12 FLIGHT International, 2 January WS brotherly Arab states and asked them to provide us urgently, if not immediately, with specific kinds of weapons. . . ." "Do we need missiles?" he asked—"of course we do." Hellenic Air Force denies losses The Hellenic Air Force Command has informed Flight that our report that "Two Hellenic Air Force F-5s are believed to have been shot down by Turkish F-102s over the Aegean Sea and it is reported that a pair of Greek F-4Es crashed on take-off from Rhodes" (Flight for October 31, page 595) is totally false. DELIVERIES to the United States Navy of Kaman SH-2 Seasprite Mk I Lamps (Light Airborne Multi purpose System) helicopters will be complete by the end of this year, the total of about 105 comprising 20 SH- 2Ds and some 85 SH-2Fs. The SH-2Fs are being converted from UH-2A/Bs, UH-2Cs, HH-2Cs and HH-2Ds, deliver ies having begun in May 1973. There are now six Lamps Heli copter Anti-submarine Squadrons (Light) providing detachments to the fleet and training replacement crews: HSLs 30, 32 and 34 based at Norfolk, Va, and HSLs 31, 33 and 35 at Imperial Beach, Calif. An additional squadron will be formed during 1975. A typical single-aircraft Lamps de tachment consists of three or four pilots and up to 14 enlisted crewmen, maintenance and support personnel, but the Navy has experimented with a smaller unit. Lamps helicopters are assigned to nine Belfcnap-class (DLG26) guided- missile frigates, the nuclear-powered frigate Truxton (DLGN35), 46 Knox- class (DE1052) ocean escorts, ten Two OF THE THREE VFW-Fokker VAK 191B lift-plus-lift/cruise V/Stol research aircraft are now about halfway through a one-year research programme partially financed by the United States Navy. The main object of the trials, which began at Manching on June 1 last year, is to assess be haviour during jetborne flight. The two German pilots assigned to the project are VFW-Fokker's Ludwig Obermeier and Government test pilot Horst Philipp. A US Navy pilot may be checked out on the aircraft later. All flights are monitored live over a telemetry link. Responsibility for various tasks, necessitating different instrumentation, has been split between the two proto- Japan examines basic trainers A Japanese Defence Agency study team is expected to visit Europe and the United States next month to evaluate a number of basic pilot trainers. The agency had intended to buy Fuji Heavy Industries' KM-2B to replace the Self-Defence Forces' 100 T-34s but Beech and other foreign manufacturers have recently been promoting other candidates. Exocet for Type 21 frigates The third Type 21 frigate for the Boyal Navy will be the first fitted with Aerospatiale Exocet anti-ship missiles and the remaining vessels will then be equipped retrospectively. Each Type 21 will carry four launchers on the B gun deck, forward of the bridge and immediately above and behind the Mk 8 4-5in gun. The two pairs Garcia-class (DE1040) escorts, six Brooke-class (DEG1) guided-missile escorts, California-class (DLGN36) nuclear-powered frigates, Spruance- class (DD963) destroyers, patrol frigates and the proposed sea-control ships. It is expected that these vessels, many of which have not yet entered service, will require more than 200 Lamps helicopters and Kaman believes that the US Navy will need extra SH-2s before the proposed Mk III Lamps is available in the 1980s. Lamps perform anti-submarine war fare (ASW) and anti-ship-missile defence (ASMD) missions for their parent vessels. Secondary roles in clude search and rescue, medical evacuation, vertical replenishment, naval gunfire spotting, visual and electronic surveillance and reconnais sance, communications relay and personnel transfer. For the ASW prime mission the SH-2D/F carries 15 ASQ-41 passive or ASQ-47 active sonobuoys, which are launched from a rack on the left side of the fuselage, an ASQ-81 magnetic- types. VI is primarily concerned with investigating the effects of jet efflux on the aircraft and its surroundings, while V2 is being operated mainly in the higher speed range of the jet- borne flight envelope. Temperature and pressure distribu tion around the first prototype are being determined to establish how air craft carriers would have to be modi fied in order to operate jet-lift V/Stol aircraft. For these tests two ground- mounted rakes equipped with sensors at various heights have been erected. VI is also responsible for examining hot-gas re-ingestion and recirculation in low-speed jetborne flight. Compre hensive instrumentation, including sensors to determine intake air of launchers will be toed in so that exhaust gases pass around the super structure when the missile motor fires. Taiwan to build T53 turboprop Avco Lycoming has received an $8-3 million letter contract from Taiwan for T53-L-701A turboprops and co-production kits. The engines will power the Republic of China Aircraft Industries Development Centre TCH- 1A trainer, which has been flying in prototype form for a year. Engine deliveries (including those co-pro duced) will be completed in 1976 and Lycoming will also supply technical equipment, services and training. The 1,400 s.h.p. T53 turboprop will complement the T53-L-13B turboshaft which is already being co-produced in Taiwan for UH-ls. anomaly detector towed on a 185ft cable from a pylon-mounted winch on the right side of the fuselage, and Mk 25 marine markers. The helicopter is launched in response to a sub marine contact by ship's sonar, using sonobuoys to redetect and locate the target and a combination of sonobuoys and Mad to pinpoint position and course. One or two Mk 44 or Mk 46 ASW torpedoes cam be carried on the dual- purpose auxiliary fuel-tank mountings. In the ASMD role the helicopter uses its LN-66 high-power search radar to detect surface targets and its ALR-54 passive detector to locate and identify hostile radars. A UH-2C has successfully launched air-to-air and air-to^surf ace missiles. The first SH-2Ds were delivered in August 1971 and became operational in December. Several Lamps detach ments saw action off the coast of North Vietnam. The SH-2F differs from the D variant in having Kaman's 101 rotor system, more powerful General Electric T58-GE-8F turbo- shafts, new landing gear designed for heavier loads on rolling and pitching flight decks, and tail wheel relocated 6ft forward to provide deck-edge clearance. temperatures, has been installed on wire-mesh debris guards which have been fitted as a precaution since air is being purposely recirculated. Even during prolonged hovering in crosswinds only minor hot-gas re- ingestion and recirculation have been discovered and the aircraft has been recovered easily. The first prototype has been fitted with roll bleed nozzles of a larger area to increase roll-control power by about 20 per cent and flight- testing has demonstrated a substantial improvement in handling about the longitudinal axis. Manoeuvring close to the ground has also provided valuable information about the accuracy which can be achieved during tracking a prede- Mk I Lamps deliveries continue VAK 191B provides data for US Navy
