Message: Why replace it? The F-15 Eagle has a perfect combat record of 101 victories and zero defeats.
during the Balkan conflict, the F-15E was the only fighter able to attack ground targets around the clock, in all weather conditions.
The Eagle's air superiority is achieved through a mixture of unprecedented maneuverability and acceleration, range, weapons and avionics. It can penetrate enemy defense and outperform and outfight any current enemy aircraft. The F-15 has electronic systems and weaponry to detect, acquire, track and attack enemy aircraft while operating in friendly or enemy-controlled airspace. The weapons and flight control systems are designed so one person can safely and effectively perform air-to-air combat.
The F-15's superior maneuverability and acceleration are achieved through high engine thrust-to-weight ratio and low wing loading. Low wing-loading (the ratio of aircraft weight to its wing area) is a vital factor in maneuverability and, combined with the high thrust-to-weight ratio, enables the aircraft to turn tightly without losing airspeed.
A multimission avionics system sets the F-15 apart from other fighter aircraft. It includes a head-up display, advanced radar, inertial navigation system, flight instruments, ultrahigh frequency communications, tactical navigation system and instrument landing system. It also has an internally mounted, tactical electronic-warfare system, 'identification friend or foe' system, electronic countermeasures set and a central digital computer.
The head-up display projects on the windscreen all essential flight information gathered by the integrated avionics system. This display, visible in any light condition, provides the pilot information necessary to track and destroy an enemy aircraft without having to look down at cockpit instruments.
The F-15's versatile pulse-doppler radar system can look up at high-flying targets and down at low-flying targets without being confused by ground clutter. It can detect and track aircraft and small high-speed targets at distances beyond visual range down to close range, and at altitudes down to treetop level. The radar feeds target information into the central computer for effective weapons delivery. For close-in dogfights, the radar automatically acquires enemy aircraft, and this information is projected on the head-up display. The F-15's electronic warfare system provides both threat warning and automatic countermeasures against selected threats.
A variety of air-to-air weaponry can be carried by the F-15. An automated weapon system enables the pilot to perform aerial combat safely and effectively, using the head-up display and the avionics and weapons controls located on the engine throttles or control stick. When the pilot changes from one weapon system to another, visual guidance for the required weapon automatically appears on the head-up display.
The Eagle can be armed with combinations of four different air-to-air weapons: AIM-7F/M Sparrow missiles or AIM-120 advanced medium range air-to-air missiles on its lower fuselage corners, AIM-9L/M Sidewinder or AIM-120 missiles on two pylons under the wings, and an internal 20mm Gatling gun in the right wing root.
Low-drag, conformal fuel tanks were especially developed for the F-15C and d models. Conformal fuel tanks can be attached to the sides of the engine air intake trunks under each wing and are designed to the same load factors and airspeed limits as the basic aircraft. Each conformal fuel tank contains about 114 cubic feet of usable space. These tanks reduce the need for in-flight refueling on global missions and increase time in the combat area. All external stations for munitions remain available with the tanks in use. AIM-7F/M Sparrow missiles, moreover, can be attached to the corners of the conformal fuel tanks.
The F-15E is a two-seat, dual-role, totally integrated fighter for all-weather, air-to-air and deep interdiction missions. The rear cockpit is upgraded to include four multi-purpose CRT displays for aircraft systems and weapons management. The digital, triple-redundant Lear Siegler flight control system permits coupled automatic terrain following, enhanced by a ring-laser gyro inertial navigation system.
For low-altitude, high-speed penetration and precision attack on tactical targets at night or in adverse weather, the F-15E carries a high-resolution APG-70 radar and low-altitude navigation and targeting infrared for night pods.
The F-15 Eagle is one of the most capable multirole fighters in the world. The F-15 entered service in 1974 and has attained an unprecedented perfect air combat record of 100.5 victories and zero losses. F-15s were responsible for downing 33 of the 35 fixed-wing aircraft Iraq lost in air combat during Operation desert Storm, and the F-15 was responsible for downing four Mig-29 fighters during the Balkan conflict. In desert Storm, the F-15E strike fighter provided devastatingly effective flying at night and in bad weather to attack numerous mobile Scud missile launchers and other high-value military and ground targets. The F-15E also maintained a 95.5 percent average mission capable rate, the highest of any fighter in the war. In the Balkans, the F-15E was the only fighter able to attack ground targets around the clock, in all weather conditions. The F-15E can carry payloads of up to 23,000 pounds and is the only fighter in U.S. production capable of performing the long-range, precision strike mission.
More than 1,500 F-15s have been produced for both domestic and international customers, and have accumulated more than 4.4 million flight hours. Approximately 1,150 F-15s are still in service worldwide with the U.S. Air Force and Air National Guard, and with the air forces of Israel, Japan and Saudi Arabia.

Subject: Hughes OH-4 Cayuse
Name:
Message: In 1960, the US department of defense issued Technical Specification 153 for a Light Observation Helicopter (LOH) capable of fulfilling various roles: personnel transport, escort and attack missions, casualty evacuation and observation.

Twelve companies took part in the competition and Hughes submitted the Model 369, nicknamed the 'flying egg' on account of its shape. The Hiller and Bell aircraft were selected as finalists, but the US Army later included the Hughes helicopter as well — which was offered at an exceptionally low price — under the designation OH-6, and five prototypes were ordered in spring 1961. The Bell was subsequently eliminated from the contest and the Hughes 369 was redesignated OH-6A 'Cayuse'. The first of the five prototypes flew on 27 February 1963 and was delivered to Fort Rucker air base the following November, to begin trials for the Army.

The Hughes aircraft was very interesting from a structural point of view. For example, the fully-articulated rotor had four blades of constant chord, consisting of an extruded light alloy spar, to which a single sheet of light alloy was bonded to form the profile of the blade. The fuselage had a light alloy, semi-monocoque structure and its remarkable robustness afforded the occupants good protection even in heavy landings. However if the compactness of the fuselage made the Hughes OH-6 light and sturdy, with low drag, it reduced the helicopter's versatility, as its small internal volume was clearly restrictive, despite being perfectly in accordance with Technical Specification 153.

The aircraft had an Allison 250 turbine engine, which was very light and compact, with a maximum power derated from 400 to 282shp, which afforded obvious advantages in terms of service life and safety. The sophisticated avionics included a track indicator, VHF and UHF transceivers and AdF. A wide choice of weapons fits was available.

Following trials, the choice of the OH-6A for large-scale production was announced in May 1965 with an initial order for 714, which was later increased to 1300 with an option on another 114. Production reached a maximum of 70 helicopters in the first month. In all 1434 were built, the last of which were delivered in August 1970.

The Cayuse established no fewer than 23 world records in March-April 1966: 2800km closed circuit; 3561km in a straight line; 227.7km/h over a 2000km closed circuit and 8601m altitude in horizontal flight. It won other records in the various classes for helicopters of a variety of weights, including a speed record of over 277km/h.

Apart from the five prototypes built for the US Army, Hughes built four others for its own research purposes, one of which was converted into a civil version designated Model 500, which flew at the beginning of 1967. The subsequent Model 500C variant had a 405shp Allison 250-C20 turbine. One OH-6A was later modified under a research programme for ARPA (the advanced research office of the US department of defense) to reduce noise levels and has been nicknamed 'The Quiet One'. It introduced a five-blade main rotor, four-blade anti-torque rotor, exhaust silencer and various noise blanketing devices on the air intakes. The new rotor has 67 per cent of the r.p.m. of the original one, allowing 270kg more payload to be carried at a maximum speed of 278km/h. A second experimental prototype, the OH-6C, with an Allison 250-C20 turbine, reached a speed of 322km/h during a test flight from Edwards Air Force Base.

The H-500MC was a military export version of the Hughes 500C, with major improvements including a more powerful main rotor of larger diameter transmission capable of withstanding higher torque values, an all-metal tail rotor and a maximum fuel capacity of 242 liters. The side windows are also different and high skid landing gear can be fitted. The armament is similar to that of the OH-6A.

Hughes OH-6A helicopters have been exported to the Brazilian Air Force (9) and Navy (6), and the Japanese Ground Self-defense Force (29). The 500M version has been supplied to the Colombian Air Force (4), Italian customs (over 60), the Spanish Navy (6 in the ASW version), denmark, Argentina, Bolivia, Mexico and the Philippines.

A later version, the 500d (500Md military) is distinguished externally from earlier models by a T-tail and five-blade rotor. The powerplant is also different — an Allison 250-C20B delivering an absolute maximum of 411shp and 355shp maximum continuous power. The increase in power and adoption of the new tail unit have led to a general improvement in structural robustness, particularly of the landing gear, the lower part of the cabin and tail boom, plus, of course, the transmission.

Current production includes the 500E, which introduces a lengthened and redesigned cabin among other improvements, and the 530F which introduces an uprated Allison 250-C30 engine for high altitude operations. Military variants of these new versions were introduced in 1984.

One of the most important orders for Hughes helicopters was for 29 of the Model 369HM built under license by Kawasaki and delivered to the Japanese Army in January 1972. The Japanese OH-6J is virtually identical to the American OH-6A, except for its performance and weight, which are conditioned by the 318shp Mitsubishi-Allison 250-C18A powerplant.

In Italy, Breda-Nardi have held the license to build and market Hughes Model 300 and 500 helicopters since 1969. Apart from various commercial orders, Breda-Nardi has supplied the NH-500M to the Italian customs. Its characteristics are the same as those of the American aircraft.

Subject: China’s Business Jet Market Explodes
Name: aaachina
Message: The otherwise dormant Chinese business jet market has come to a turning point, triggered by the air control relax reform. This week, Airbus and Boeing have held their press conference, predicting that each of them will sell over 5 business jets to China each year, while Bombardier also showed that over the next 10 years, total sales of business jets in China will reach over 600 units.

According to Li Bing, sales superintendent of Boeing Greater China, government, large corporates, business leaders etc are their main clients. This year Boeing is expected to deliver 3 business jets, mainly to VIP charters such as Hainan Airlines, and Air China. Upto now Boeing has sold 195 business jets worldwide. Although only with 8 Boeing jets, China is among the fastest growing regions.

Comparatively, Airbus’s business jet marketing in China is much quicker. Among its 170 sets of business jets sold worldwide, China owned 20. This year Airbus has already sold 2 jets to China, to be delivered to deerJet and Southern Airlines. Last year, Airbus sold 15 business jets worldwide, China took 15%.

The largest business jets represented by BBJ (Boeing) and ACJ (Airbus) with dozens of passenger capacity, have a space 4 times that of smaller ones such as Bombardier and Gulfstream. Their flight range is also much longer. However, with the convenience of spareparts and repair service sharing of their mainstream jets, their operation cost is yet lower than those smaller jets, therefore the big business jets of Boeing and Airbus have been securing their position as the topmost business jet suppliers.

In the myriad of business aircraft types, helicopter is also an important member. EuroCopter, world’s largest helicopter manufacturer said, along with the opening of the low sky, demand of helicopters in China will also be released, which is suppressed for too long.

Recent data showed that currently China has no more than 100 private jets, while the U.S. has more than 18000 business aircrafts.

At the moment, the Beijing Capital Airlines, which is a joint venture of Hainan Airlines and Beijing Capital Tourism, is the largest business jet operator, Its predecessor was the deerJet. Capital Airlines has 24 business jets, and hence has the largest fleet in Asia Pacific region, accounting for 90% of China’s total fleet. To meet with the market change of wealth redistribution to the Orient, China Airlines, Eastern Airlines and Southern Airlines are also planning for the business aviation.

China Airlines plans to set up a joint venture with the Beijing Municipal Government to operate VIP chartering. A new type of BBJ jet will be purchased. Previously the China Airlines has only 4 Gulfstream jets under management. Eastern Airlines invested RMB 50 million in a business jet charter company in 2008, and plans to increase its fleet to 3 this year. Southern Airlines, until now not yet involved in business aviation, has also planned to procure a ACJ business jet, and will probably found an independent business jet company.

However, air control in China has impeded the business jet chartering. Passengers are unable to drive directly to beside the jet to get aboard, nor can they alter their route at the last moment. In addition, apart from a few cities with business jet terminals, the rest of Chinese cities have no specialized facilities for business charters. These two factors have become the two largest barriers towards successful development of the Chinese business aviation market and industry, therefore, industry insiders predict that it needs time before the market will really take off.

Subject: Aircraft that should return to the air
Name: v_bomber
Message: TSR2 it was MORE advanced than the tornado and it origanated from a 1956 order (english eletric actually began work in the late 40s!!! Thinking that ot would be wanted) It was more advanced than f111 they were worried that if we exported it f111 sales would fall dramitically It got everything right and was better than the order specification. The first prototype flew over 20 flights but there were many prototypes after it.

The second prototype would never fly; the government, in the Budget day announcement on the 6th of April 1965, announced that the TSR.2 programme was to be terminated immediately. The aircrew were at the time having lunch in a pub near Boscombe down; on hearing the shocking announcement they rushed back to the airfield in an attempt to get XR220 into the air and to at least present the government with a second flying prototype. This was not to be; permission was denied. While the management of BAC were informed before the budget speech was made, they were forbidden to tell their employees, who then had to hear the news on the radio. The House of Commons was in uproar over the cancellation; but no debate could take place during the budget speech so not only had the government treated BAC's workforce with contempt, they had tried to slip a major defence project cancellation past the opposition. A debate one week later in the house was a rough ride for denis Healey (the new defence Minister), who tried to justify the cancellation on the basis that the F-111 could be bought more cheaply, though he could not state a cost or exact timescale for the buy. Healey has since stated that getting American backing for an International Monetary Fund loan was not a reason behind the British order for the F-111 instead of continuing the TSR.2 programme. However, the TSR.2 was certainly a serious worry to the Americans, being vastly more capable than the F-111 and could have made a serious dent in the F-111's export prospects. A denial from a politician, as the TSR.2 programme showed on numerous individual occasions, is not worth the paper they refuse to write it on.

'The distant flash of lightning howling through the thunder' ex RAF ligthning pilot recalling lightning of 1973 through thunder

Subject: Please identify mystery UK all-grey prop plane
Name:
Message: Please help solve this mystery which has been intriguing me for a long time.

In the summer of 1987 (or thereabouts) I was a student in durham city, durham county, UK. One day I was sitting at my desk next to the window working. I was on the top floor of a tall long terrace of houses of three or four stories (I think the street was called Old Elvet), which was on the edge of shallow valley so that I was overlooking the meadows towards the river. (Not the very steep valley near the cathedral).

I happened to look up, and was surprised to see a small airplane silently coming in a glide towards me (to be exact it was a little to one side) with the engine switched off. It was about to crash into the terrace of houses, but at literally the last second the engine was switched on and it just managed to hop over the roofs. I had not heard it before, so it may have had the engine turned off for a long time.

The aircraft was unusual. It was painted all over in the same shade of light grey - the same shade as an overcast sky. I presume this was to camoflage it against the sky. I do not remember any identification letters. It also had what I think might be called a rotary engine as I could see the piston cases arranged in a circle around the propellar shaft. The wings were fixed at the roof of the cabin. It was not a Cesna or any modern plane. It looked like something out of the 1930s or 1940s perhaps.

I would like to know, not so much which brand of plane it was, but who owned it?

It might perhaps have been a local Air Cadets group doing a training run, but this seemed incredibly dangerous to do, since if the engine had not started, or if there had been a slight miscalculation by the pilot, then he/she would have crashed and probably died.

I also had a very tenuous 'romantic' link (an unwanted and unwelcome link both then and now) with someone whom I have recently learn had become extremely successful in the entertainments industry at that time. So I have wondered if it was a spy plane used by the tabloid press or some freelancers to try to take a snap of me? (OK, so maybe I'm paranoid!)

Could anyone tell me anything about this mystery plane please? Thanks.

the b36 was superceded by the b47 and by the time it was completely removed from service, the b52. both of these were a generation past the b36--swept wing high subsonic jets with mid-air refueling capabilities. they could also carry the same or more in terms of payload. the b36 was essentially a pre-ww2 design that didn't fly until after the war ended. it was an anachronism.

the sr71 is a great aircraft. however it is 5 times more expensive to operate than the u2. on the other hand it only takes 1/4 the time to fly a mission. its special capabilities are no longer needed however. satellites have taken over the recce mission especially over extremely hostile territory--china, russia, etc. the u2 is also much more mission adaptable. wing pods with extra sensors can be added.

the f4 phantom ii was replaced by the f14 and f15 in the navy and usaf respectively. both of these aircraft are much more capable in every way in comparison to the f4. also of mention is the fact that they were designed to operate much better in the subsonic--especially in a dogfighting scenerio. the f4 after all was not much more than a flying brick at low speed.

the yf23 was deemed not as good as what has become the f22. in that fly off many criteria were looked at.

the c123 was not nearly as capable as the c130. talk to anybody who deals with airlift and they will tell you that anywhere you can put a dc3 down you can put a c130 down. and it can carry so much more than the old c123.

usaf still has some c141 aircraft in its inventory. they have mostly been replaced by the c17. the c17 can carry much more cargo and land it on shorter and rougher strips.

the f20 was a great follow on to the f5. however a few crashes during the showings to many countries all but doomed it. the last nail in the coffin was that usaf didn't buy any. so all the prospect customers decided to buy the f16 instead. the f16 is a much more capable aircraft and can carry a lot more external stores.

the f101 voodoo was a great post-korea interceptor. by vietnam it had been eclipsed by better aircraft like the f4.

the f105 was nothing more than a high speed bomber. it was not designed to tangle with other fighters. as such it was inferior to the f4 in many respects. and by far it was inferior to the f15. it was also lost in greater numbers over vietnam than any other fixed wing aircraft.
