(Military History) Bell's YAH-63 attack hellicopter

When U.S. Army and Marines start AAH(Advanced Attack Helicopter) project in 1972 as succession of AH-1 Cobra attack helicopters. this pictures are Bell's YAH-63 attack hellicopter that nominated with Huges(now merged by Boeing) YAH-64 attack helicopter in 1975. YAH-63 stand out 2 blades in opposition to 4 blades of YAH-64.
YAH-64 won the AAH project September, 1976 so YAH-63 naturally diappeared.

A-10 Thunderbolt II, together with F-15 and F-16 is a jet aircraft taking upon itself the burden of the United States Air Force in the 1980's. The original craft made its first flight on May 10, 1972. Military dispositions to the units have been started since March 1976. The extremely unique shape of A-10 was created being devoted to the assignment of ground attack. With its ample military equipment for ground attack and a 30mm gatling gun which can scrap a tank at one blow, it has great power over the tanks of the Warsaw Pact forces.

Following a 1972 U.S. Army requirement for a new Advanced Attack Helicopter to replace the AH-1 Heycobra. Two manufactures were chosen to build competition proto types, Bell YAH-63 and Hughes-64, the latter winning the competition and making its first flight on 30 September 1975. After protracted development with several machines, in 1980 the Martin-Marietta TADS/PNVS (Target Acquisition and Designation Sight/Pilot's Night Vision Sensor) was adopted for the night attack role. The name Apache was adopted in 1981 and production of the AH-64A began in 1982; in 1984 Hughes was absorbed by McDonnell Douglas. Operation Desert Storm in 1991 saw the first major conflict for the U.S. Army Apaches, where they devastated Iraqi armour, using Rockwell AGM-114 Hellfire laser-guided anti-tank missiles, podded 70mm Hydra rockets and the 30mm M230 chain Gun under the nose. The front cockpit houses the copilot/gunner and the pilot occupies the raised rear cockpit. A total of 821 Apaches was delivered to the U.S. Army by 1996. Experiences in the 1991 Gulf War rapidly led to the development of the AH-64D Longbow wersion, with its very powerful and sophistcated long range fire control radar (FCR) mounted above the rotor head. The Hellfire ATM requires a direct line of sight with the target, and together with completely new advanced avionics systems, much of its housed in the enlarged box fairings each side of the fuselarge. the Apache could now detect and attack targets while remaining virtually hidden from the enemy. Another advantage of the radar is that it can simultaneously survey, scan and track over 1,000 targets at long ranges even in the worst visibility conditions, and of these it can identify 128 with attack priority automatically given to 16 of these for a full load of hellfires.

Grumman (now Northrop Grumman) has long been closely associated with air borne early warning (AEW) for U.S Navy carrier borne aviation. The Hawkeye was designed from the start as an AEW aircraft. unlike its predecessor the Grumman E-1 Tracer, which was an adaptation of the successful anti-submarine S-2 Tracker series. The design of the Hawkeye resulted from a successful blend of several conflicting requiremants. these being an airframe able to carry the large dorsal radome giving full 360 degree coverage for the powerful APS-96 long range search radar; long range and endurance, low approach speeds for carrier operations and the need to fit on carrier decks and lifts for hangar stowage below deck. For the last mentined requirements, the wings can be folded rearwards, parallel to the fuselage and the rotodome lowered. The long span high aspect ratio wings incorporate high lift devices for long endurance and lower speeds. First flwn on 21 October 1960, the E-2A Hawkeye first entered service in 1964 and from the late 1960s most of the 50 aircraft were converted to the more capable E-2B.

The Panavia Tornado has been in large scale series with the air forces of Great Britain, German and italy since 1980, when the first unit, the Tornado Tri-national Training Unit (TTTE) formed at RAF Cottesmore. In recent years the type has received several upgrades in avionics, engines and weapon ; the latest GR4 version is also in service. First used operationally by the RAF and Italian Air Force during the 1991 Gulf War more recently Tormados saw action during the Kosovo conflict in 1999. At the peak of its RAF service there were 12 operational GR1 squadrons based in the UK and in RAF Germany; since the end of the cold war and general military force reductions on all sides. RAF front line units have shrunk to eight. During the 1990s the squadrons had dedicated roles;  in the UK nos. 2 and 13 are primarily equipped with the GR1A for reconnaissance and nos. 12 and 617with the GR1B for maritime strike. In RAF Germany four squadrons reside at Bruggen; of these nos. 9 and 31 are primarily dedicated to the SEAD (Suppression of Enemy Air Defences) role using the Bae ALARM (Air Launched Anti-Radiation Missile), first used in the 1991 Gulf War, while nos. 14 and 17 have a precision bombing role and are equipped with TIALD (Thermal Imaging and Laser Designator) pod, also first used in the Gulf War; (No. 17 Squadron was disbanded in March 1999) More recently some of the dedicated roles have become less well defined and, for example, many of the units can engage in the overland and maritime bombing roles as required. The concept of the Bae ALARM missile is unique and in any mayor conflict the Tornados of nos. 9 and 31 squadrons would be amongst the first to enter enermy airspace. When flying almost within range of enemy radar's several ALARMS will be launched to high altitude where rocket motors are cut. Each missile slowly descends on its parachute, all the time searching for any enemy radar beams it can lock onto; if detected, the parachute is jettisoned and the rocket motor restarted to drive the missile into its target. The Tornado can carry a wide variety of stores and weapons and during the comming years new weapons and further upgrades will be introduced to ensure that Tornado remains operationally effective; carrying the 2,250 ltr.

The Dassault Rafale is a new-generation ultra-modern twin-jet combat plane. It means the combat requirements for the next century, combining in a  single plane the multiple roles that otherwise would be carried out by many different types. The Rafale M is the carrierborne naval version equipped with a reinforced under carriage for catapult launching. Equipped with two SENCMA M88-2 engines (each with 75 KN thrust) the Rafale reaches a speed of  Mach 2. Its long range. Enormous load-carrying capacity, precision fire control and survivability gives the Rafale exceptional mission effectiveness. In addition it is the best combat plane in the world that can engage in simultaneous ground attack and air defence actions. The first production-plane goes into service with the French navy in 1999.

Still shrouded in much secrecy following its development by the Russian Sukhoi design bureau, the revolutionary S-37 berkut(Golden Eagle) first flew on 25 September 1997 from the Gromov flight test centure at Zhukovsky, near Moscow. For many years, there have been several concept models and some aircraft built with forward swept wings (FSW) - examples being the experimental Smerican Grumman X-29 and the production German HFB 320 Hansa Jet - the basis for all of these designs originating with German research during World War Two. At the end of the war the Soviet captured the prototype Junkers Ju287, a four - engined jet bomber with FSW. Following modification, this aircraft flew in 1948 as the EF 131, and was later modified into the EF 140 : the Russians also developed the Tsybin LL-3 rocket powered FSW project. News of the existence of the S-37 (originally S-32) project first became known in 1993 with an announcement design with FSW was being developed for Sukhoi : little more was known until the S-37 appeared and even now many details of its complex design remain secret. The FSW jas several advantages over the conventional seept wing, especially at transonic speeds, for aircraft operating in the air combat role : wing torsional stiffness is markedly increased especially with the use of composite materials, while drag factors, manoeuvrability, landing and take off performances can all be improved. The berkut prototype was founded by Sukhoi and makes use of several of their existing component parts from other types, including the undercarriged of the Su.27K : it is powered by two Aviadvigatel D-30F6 turbojets each rated at 93.2kn(9.509kg/20,956 lbs) dry thrust and 152kn (15,503kg/34,177) with afterburners. Detailed performance figures have not been released but maximum speed is estimated to be about 1,400km/h (870mph) at see level and 2,200 km/h (1,367mph) at altitude. The S-37 Berkut is a proof-of-concept prototype and its future development status is presently incertain : two factors which may affect this are a possible lack of funding and major differences between the interested civil and military procurement authorities.

In other to be used in a CIA top secret project. Airwolf, advanced supersonic helicopter invented by Doctor Moffet, a demoniac genius, was carried away to a certain country by Doctor himself on the date of its demonstration. On a request from Archangel, director for CIA, Stringfellow Hawke, a lonely ace pilot, infiltrated into the country together with his close friend, Dominic Santini, and successfully took back Airwolf. Hawke, however, didn't return Airwolf to CIA but hid in the desert area. He insisted that he would return Airwolf onthe condition that CIA helps him to find his brother, John, who had been missing in Vietnam. On the other hand, Archangel asked Hawk to cooperate with them using Airwolf in the CIA project in return for provision of information about Hohn. Hawk accepted the condition. Thus, Airwolf started flying all over the world.
Airwolf is the attack helicopter for combat that CIA developed expending a $1 billion budget and 20 years of time. It is equipped with various armament and high-performance equipment, and its combat power is comparable to one division of troops on foot. This kit which reproduces Airwolf called a flying fortress is a 1/48 scale model using a "completely new mold", and the chain gun & cannon, ADF pod, landing leg, main rotor & tail rotor, precise cockpit, etc. which appeared in the drama are also reproduced realistically. An angle-adjustable display stand is included.

ACADEMY PLASTIC HOBBY MODEL KIT 1/72 B-17G Flying Fortress "Special Nose Art Edition"

In 1935 Boeing's entry into the Army Air Corps multi-engine bomber competition was a daring gamble using the company's own resources and money. Boeing correctly anticipated that aircraft larger and faster than the usual twin-engined bomber would be the way of the future. From 1935 until production ceased in April 1945, a total of 12,726 b-17 Flying Fortresses of all types were produced. The last production type and the most numerous was the B-17G which had the greatest bomb load and range of any version. It was the B-17G that did the most damage to German occupied Europe and devastated the production capacity of Nazi Germany with its countless daytime raids. In this day of multi-million or even billion dollar military aircraft, it should be noted that the average cost of a ready-to-fly B-17G was only US$ 238,329, a mere pittance by today's standards! Today, over two dozen B-17 Flying Fortresses are in museums or tlying collections.
