F-22

Beyond the Observable

Ever since man took up arms against his fellow man, humankind has sought out ways to gain the upper hand in battle. In the case of cloaked or stealth aircraft, a number of nations have attempted to develop ways to detect that which is supposedly “un-seeable”, or at least get a better understanding of what they are confronting in the modern battlespace so that measures can be brought to bear to unravel their advantages.

One of the latest developments arising from the so-called “stealth wars” is IRST. An infrared search and track (IRST) system (sometimes known as infrared sighting and tracking) is a method for detecting and tracking objects which give off infrared radiation, such as the infrared signatures of jet aircraft and helicopters.

IRST is a generalized case of forward looking infrared (FLIR), i.e. from forward-looking to all-round situation awareness. Such systems are passive (thermographic camera), meaning they do not give out any radiation of their own, unlike radar. This gives them the advantage that they are difficult to detect.

However, because the atmosphere attenuates infrared to some extent (although not as much as visible light) and because adverse weather can attenuate it also (again, not as badly as visible systems), their range compared to a radar is limited. Within range, an IRST’s angular resolution is better than radar due to the shorter wavelength.

To date, Hobby Master has done an admirable job of modeling some of the latest experimental aircraft still undergoing testing by the USAF, all in an effort to once again gain the upper hand in aerial warfare. Their “chrome” covered F-22s sold out almost the moment they became available and are now commanding prices well in excess of their introductory price. That said, the USAF is conducting field testing of other experimental aircraft, eventually choosing the best means of protecting their aircraft in combat for the foreseeable future. The so-called “symbiote” F-22 represents another step towards remaining stealthy in aerial combat.

Nicknamed “Disco” or Symbiote F-22, the new Raptor with a reflective coating has been one of the highlights for the photographers gathered outside Nellis Air Force Base for Red Flag 22-2.

A second F-22 with a mirror-like coating has been spotted flying out of Nellis AFB, Nevada. As already explained, the new coating on this second stealth aircraft appears to be much different than the one on the Raptor [IDed as airframe #04-4065] that made its first appearance in November 2021: it features smaller, mirror-like tiles applied on the nose section, weapons bay doors, fuselage and also inner and outer face of the twin tails.

Hobby Master is already hard at work developing a model based upon the symbiote scheme. While pre-production photos are still a couple of months off, the manufacturer did release a four-sided illustration that ably demonstrates the look of their newest F-22. It is our belief that HA2828, as it is currently known, will instantly become a hit when it is released in 2024, and become hard to get in the after market. That said, there’s still time to pre-purchase this model before it flies off for the great blue yonder.

Product Spotlight: Mirror, Mirror on the Wall

In the world of technological advances, what works one minute may not work the next. Take the Lockheed-Martin F-22 Raptor as a prime example. Billed as a cutting-edge fifth generation fighter, the aircraft may already be showing its age, faced with some unexpected challenges that could put the platform in jeopardy in the not-too-distant future.

In June 2020, the “War Zone” reported that a 401 “Son of Ares” technology demonstration aircraft had conducted multiple test flights over the China Lake Naval Aviation Weapons Center. The surface of the aircraft was covered with a layer of highly reflective metal coating. Its stitching quality is similar to what we saw on this F-22. At the time, the US media assumed that this could be used to test advanced infrared sensors, and even low-power laser systems, as well as the aiming capabilities of these systems for specular reflection targets.

According to the report, the US military is currently conducting a large number of infrared search and tracking systems (IRSTs) tests, which are in the process of early deployment by the US Air Force and Navy. The US military is also developing an air-to-air laser weapon system.

In 2021, scientists developed a new type of stealth coating. This type of stealth coating is a lightweight anti reflective coating based on the structure of a moth’s eye that could make aircraft invisible to radar. The secret to the new coating is the creation of millions of tiny hollow spheres of carbonized sugar, arranged in a tightly-packed hexagonal monolayer. These spheres absorb nearly all radiation used by military targeting radar and law enforcement speed traps.

A coating which is 100 per cent anti-reflective in visible light would appear as a shapeless black mass, while one which had this property in the microwave range would be completely invisible to radar. The secret is the size of the biopolymer beads which form the hollows inside the coating, which at around 6mm are slightly smaller than the wavelengths of microwave and radar beams, and the thickness of the carbon walls that surround them.

Expect this latest technological marvel to land in June.
