equipment in accordance with the order, the world has or will be equipped with low-observable combat aircraft in four models: F-117, B-2, F-22, F-35, are model-to-ground attack machine, strategic bombing model machine, heavy duty air combat model machine, medium-sized multi-purpose type machine, the author has stressed that the “model unit” concept, is to remind you readers and friends, in the United States, NASA and major aerospace manufacturers of the weapons development laboratories, experimental fields and wind holes and countless low-to combat aircraft to detect pre-research project in progress, these pre-research project in a few likely will in the near future as the author calls the “machine model” (developed by the engineering capability with full combat equipment models) , there will be low or even non-combat aircraft types can be detected. We will be faced with the threat of not only the four actual equipment before, or is equipped models will be equipped with machines, but the entire concept of low-observable aircraft of the war situation brought about all the changes. Can not be how to deal with low-observable combat aircraft to properly resolve this historical problem, we will suffer on the battlefield in the future can not afford losses.

flying birds of prey base – low-observable technology, real threat

F-117 “Nighthawk” Americans understand the experience of low-observable technology is a killer, but only with low-observable features does not bring the killer to maximize the performance level. With the gradual growth of human aviation industry and aviation engineering technology advances, more importantly, is accompanied by a variety of low-observable combat aircraft involved in combat to achieve the basic theory of slowly mature, true low-observable threats started to emerge. This time, not like “Nighthawks” as slightly flawed, but the U.S. aviation industry development and growth and accumulation of industrial technological base strong vigorous outbreak.

the United States in 1971 called “advanced tactical fighter,” the air pre-research project, the achievements of the most powerful, most advanced fighter is also the most threatened of the heavy F-22 “Raptor”, it and F-35 is the real threat of this most important content. F-22 from the United States ? Lockheed Martin, Boeing and General Dynamics jointly design a new generation of heavy-duty low-observable aircraft, the main task to achieve and maintain a theater of the air, in the design with the supersonic cruise, BVR combat, high maneuverability, low radar and infrared detection and other features available. F-35 “Lightning II” is the United States ? Boeing and Lockheed Martin-developed multi-purpose tactical attack fighter, the F-22 together with the composition of the severity of the United States with a new generation of fighter aircraft.

people usually four generations of fighter aircraft performance will be attributed to the following four characteristics: low-observable, supersonic cruise, integrated avionics systems and super-normal mobility, but these points in the design of performance Unlike any previous fighter characteristics, there is no direct statement of how the formation of four generations of machine real operational advantages, and in discussing low-observable combat aircraft, especially the U.S. low-observable combat aircraft data, is always filled with a large number of dazzling ideas and terminology. This makes it difficult to grasp a clear and focused combat aircraft low observability real advantage.

I put together low-observable fighter real operational advantages attributed to the following formula:

advantage of low-observable fighter=difficult to find real spectrum advantage + comprehensive information advantage + firepower advantage.

below will be discussed and analyzed separately.

sophisticated low-observable fighter has to get rid of the “Nighthawk” Time can only be approximated by the polyhedral approach to low observability and aerodynamic design limitations, the modern form of advanced military giant military computer processor performance far lead generation, coupled with years of research come to fruition under the low observability and aerodynamic comprehensive algorithm software, the architecture from low observability and aerodynamic balance of low-observable aircraft design platform. F/A-22 low-observable design features are evident, most notably through a large number of parallel design back to the wave peak concentration to a few non-critical direction, the head-on RCS (RCS) of about 0.06 square meters, lateral RCS in about 2 square meters, compared to RCS easily a dozen or even dozens of square meters of conventional aircraft like the specter of a general. Not only that, with very good performance under the premise of low observability, “Raptor” in air also reached the pinnacle of today’s fighter aircraft design, the era of supersonic cruise across the unconventional and even make it even more powerful motor.

signal is king – the advantages of the radar burst

If the “Raptor” low observability and aerodynamic shape design of two-Gu Shuangquan able to enemy air defense positions in the strict containment and air superiority forces succeeded in seizing control of the air is still, then four generations of low-observable fighter in the great advantages of radio frequency management, enough so that the enemy can not see radio waves in the battle to be naked force.

usually someone lower in the fourth generation of fighter aircraft can detect when the often advanced active phased array radar, cockpit displays and integrated avionics systems together, in fact, this reflects a Electronic Science and signal processing for scientific confusion, although they both sound and electronics-related, and in the traditional view seems to be together, but in fact the radar system, radar warning systems, communications systems and electronic warfare systems, and signal processing is the signal theoretical research, although they are covered within the scope of avionics systems, and avionics systems architecture, data bus and high-speed processors are usually in the electronics or microelectronics.

Perhaps the reader will feel there’s something difficult to understand, I try to use words the difference between these two areas of expertise make it clear that: “Signals and signal processing science” to explore is how the electromagnetic signal change into the way we want, that is, signal processing algorithms, “e-science” to explore is how the signal processing algorithms with the actual circuit. Although we usually say “electronic warfare”, but actually to confront the electronic equipment but not the signal.

F-22 “Raptor” equipped with the APG-77 AESA radar and ALR-94 radar warning receiver, F-35 “Lightning II” equipped with the AN/APG-81 radar and more function integrated RF systems/electronic warfare systems. The two types of active phased array radar in addition to traditional radar functions, are also used for reconnaissance, electronic jamming and communications.

suggested that low-observable aircraft in order to achieve true low-observable, it must be all off the radar and communications equipment does not emit electromagnetic signals, or to maintain “radio” silence, to arrive at low-observable machine not terrible conclusion. If you want to attack low-observable fighter aircraft radar must be open, or must rely on other machines of the sensor, and this time the enemy will attack perceived themselves to be irradiated to avoid or fight back, if low-observable aircraft can not free to use their own radar, and that its operational effectiveness is clearly not as terrible brochure. The theory in F-117 “Nighthawk” era is set up, in fact, “Nighthawk” in order to achieve low observability, to avoid the use of active sensors, but the “Nighthawk” and there is no genetic defects to their offspring, the popular The use of passive anti-low-observable radar detection unit can detect the low position, then attack tactics probably will not have any effect.

fact, AN/APG-77 and AN/APG-81 have not simply airborne fire control radar, but the multi-function radio frequency management system, if the characteristics of this work can be described both , that is: multi-function radio frequency management system=to burst as the main means of spread spectrum frequency hopping can be intercepted features low sensitivity of the threat warning + + + multi-active radio frequency integrated electronic warfare.

U.S. Global Strike Task Force will be the world’s first tactical combat aircraft low-observable, strategic low-observable combat aircraft and other advanced information and intelligence platform mix compiled, on a large scale, the organized use of “All low-observable” air combat force. Including one by the 12 B-2 consisting of low-observable bomber force ,2-4 from the 48 F-22 consisting of low-observable fighter squadrons, usually four B-2 and a squadron of F-22 as the basic combat units, support units, including the U2 reconnaissance aircraft, EP3 and RC135 reconnaissance electronic reconnaissance system composed by the E3 AWACS, EC130 and E8 battlefield command center consisting of ground targets, airborne surveillance aircraft early warning and command and control system, also to get unmanned aerial vehicles, space-based information systems and support ground-based sensors. Global Strike Task Force 1-3 days, mainly for the war against the enemy’s critical battlefield remote node. Technical decisions and tactics, global strike task force to break through the enemy machine can detect low air defense system for U.S. air power to full advantage on the ground that a key role in combat, when the enemy high value targets within the battle and battlefield objectives in the war to support node team within a few days to be fully destroyed, the enemy’s combat system will collapse, large quantities of conventional combat aircraft from a global clean-up task force to combat the influx of safe passage out, the loss of the system to support a variety of enemy firepower and information operations units of all the clean-up out.

actually “Raptor” air superiority on the battlefield is not the main task of the implementation of the amount of combat platforms, “Raptor” only need to clean out the enemy important information with the support of aerial firepower nodes, and in the relatively safe place for friendly fire support and provide information and sufficient to cover a significant impact on the battlefield. Low-observable air superiority over the machine is just a catalyst, can greatly accelerate the process of aerial combat, the tactical situation to promote the transformation and maximum air power to avoid the loss of one’s own. Similar to the “Raptor” This high-end low-observable air superiority over the machine due to cost reasons, can not, as second generation or third generation machines, as a lot of equipment, but this is not to underestimate its influence on the basis of the war situation. Machine can detect low air superiority role similar to the “Swordsmen”, only appear when needed in the friendly, then “will take the enemy’s heads,” as the soldiers did not go as strikes, its role is to make a hundreds of aircraft fleet of three generations of machines capable of air superiority mixed with a few “Raptor”, like after the expansion as fermentation, three generations of machines is to allow the United States is entangled with the enemy, when combat aircraft play a key role to turn things around, is the enemy closely guarded but friendly parties need to kill the array through the air to open up a channel.

Although the “Raptor” is more important and critical, but I thought that “Lightning” 2 is the more noteworthy threats, “Raptor,” the master of the characteristics that make it not cost a lot of equipment and deployment, and “Lightning” 2 but adhering to the principle of the development cost can be spread to a wide range of every corner of the world, a type of advanced, low-observable, with the popularity of multi-purpose combat capability will be a combat air power redistribution of the storm. Japan, Singapore, Australia and Taiwan may even have been identified equipment, “Lightning” 2, then our tactical air power and ground air defense system to face the bulk of low-observable groups combat aircraft, the security threat can never be overlooked.
