The Russian Air Force's Super Weapon: Beware the PAK-FA Stealth Fighter

 

 

Should the West be worried about Russia's next-generation fighter-jet? 

Dave Majumdar

The Russian Sukhoi T-50 PAK-FA stealth fighter could prove to be a formidable competitor to American fifth-generation combat aircraft such as the Lockheed Martin F-22 Raptor and F-35 Joint Strike Fighter. Indeed, in some measures, the new Russian warplane will exceed both U.S.-built jets, but the PAK-FA is not without its flaws.

“The analysis that I have seen on the PAK-FA indicates a pretty sophisticated design that is at least equal to, and some have said even superior to U.S. fifth-generation aircraft,” former U.S. Air Force intelligence chief Lt. Gen. Dave Deptula told the National Interest. “It certainly has greater agility with its combination of thrust vectoring, all moving tail surfaces, and excellent aerodynamic design, than does the F-35.”

Indeed, the PAK-FA appears to be optimized for the air-superiority role like the F-22 more so than the multirole, strike-optimized F-35. Like the Raptor, the PAK-FA is being designed to fly high and fast to impart the maximum amount of launch energy to its arsenal of long-range air-to-air missiles—which would greatly increase the range of those missiles.

“Performance-wise it certainly looks to compete with the Raptor,” one senior military official with extensive experience on U.S. fifth-generation fighters told the National Interest.

Like the F-22, the Russian machine is expected to be able to cruise supersonically for extended periods of time—probably faster than Mach 1.5. The aircraft’s maximum speed should be greater than Mach 2.0—assuming its low observables coatings can handle the stress.

However, unlike the American fifth-generation aircraft, the PAK-FA places less emphasis of stealth, and much more emphasis on maneuverability. While it could compete with the Raptor in terms of raw kinematic performance, the PAK-FA greatly exceeds the F-35. And that performance margin might increase.

The Russian aircraft is currently powered by modified versions of the Su-30 Flanker’s engines called the Izdeliye 117 or AL-41F1, which produce about 33,000 pounds of thrust. The engine, which runs far hotter than the original AL-31 engines from which it was derived, is not proving to be as reliable as initially hoped. But the current engines are only temporary. Later production variants of the PAK-FA are expected to be powered by a new engine called the Izdeliye 30, which should enter service in 2020.

The Russian jet is also equipped with a powerful avionics suite, which is an evolution of Sukhoi’s work on the Flanker-series fighters. “Indications are that the avionics are derived from the Su-35S with the addition of a very high power-aperture X-band multimode AESA radar,” Deptula said.

Further, there are indications that the PAK-FA is also equipped with L-band radar arrays, which are able to detect the presence of a fighter-sized stealth aircraft. While the L-band radar would not allow the PAK-FA to target a stealth aircraft, it would allow the pilot to focus the jet’s other sensors on a particular area of the sky.

In addition to radars and electronic support measures, the PAK-FA is equipped with infrared search and track capabilities.

While the Russians have made enormous leaps in their sensor capabilities, U.S. warplanes still hold the edge in terms of sensor and data-fusion, which is critical for modern warfare. “The real question is can the Russians achieve the same degree of data fusion and networking capabilities of the F-22A and F-35—right now I’d put my money on the U.S. and our allies in that regard,” Deptula said.

A senior U.S. industry official agreed with Deptula’s assessment. In terms of its avionics, the PAK-FA is closer to a Boeing F/A-18E/F Super Hornet or F-16E/F Block 60 than an F-22 or F-35. “Some may claim that the PAK-FA is a 5th gen. fighter, but it's more of a 4.5 gen. fighter by U.S. standards,” the industry official said.

In fact, the PAK-FA’s lack of true sensor fusion and comprehensive data links that are on par with its American counterparts may prove to be its Achilles’ heel. U.S. strategists are moving towards an approach where every aircraft or surface ship can act as a sensor for any aircraft, ship or vehicle that carries a weapon. The launch aircraft might not even guide the weapon once it has been fired. The U.S. Navy is already implementing a construct called the Naval Integrated Fire Control-Counter Air (NIFC-CA) that would do just that. The Air Force, too, is working on something similar.

“In the future—while aerodynamic performance will continue to be important—speed, range and payload to a greater degree than maneuverability. Even more important will be the ability to ubiquitously share knowledge to the point that we have faster decision advantage than any adversary,” Deptula said. “This is the notion of the ‘combat cloud.’ It’s more about how we integrate the sensor-shooters that are resident in systems coming online, more than it is about new platforms.”

Protecting mineral treasures of Antarctica's Larsemann Hills - 4

 

Blue prisms of the borosilicate grandidierite in gneiss with the aluminosilicate sillimanite (white prisms) and the borosilicate tourmaline (dark) can be seen in this sample from the Wilcock Bay area on the southern Stornes Peninsula. The sample was collected as part of a research study of minerals in the Larsemann Hills in Antarctica. In November 2003, Edward S. Grew, a research professor in the School of Earth and Climate Sciences at the University of Maine in Orono, and Christopher J. Carson, a senior Antarctic geoscientist with Geoscience Australia in Canberra, were part of a team of researchers that travelled to Antarctica's Larsemann Hills as part of a study to determine how abundant boron and phosphorus were in the area, and to suggest an explanation for why there might be an exceptional enrichment there. The trip began a decade-long research project that culminated in the 2014 designation of the area as an Antarctic Specially Protected Area (ASPA). The Larsemann Hills are a 40-square-kilometer region of rocky islands and promontories on the eastern shore of Prydz Bay. Previous studies of the area suggested that boron and phosphorus were there in large quantities, which would be particularly exciting because the two elements are rarely found in more than trace amounts in highly deformed and metamorphosed rocks such as the granulite-facies metamorphic rocks exposed in the Larsemann Hills.   You can read the entire story about this expedition online in Earth magazine, "Protecting the mineral treasures of Antarctica's Larsemann Hills."

Spectacular, randomly-oriented prisms of the borosilicate mineral prismatine on a foliation plane can be seen in this outcrop east of Prismatine Peak. Originally reported to be tourmaline--a relatively common borosilicate--by researchers in the late 1980s, later research found that the large prisms were actually prismatine, another silicate mineral containing boron as an essential constituent but far more limited in occurrence. Correcting the mineral identification resulted in the renaming of "Tourmaline Peak" to "Prismatine Peak," the official name for the prominent hill on central Stornes Peninsula where prismatine spectacularly occurs.

Researchers studying minerals in the Larsemann Hills set up their camp on Stornes Peninsula. This view, taken facing north, was taken after the researchers returned to camp from a traverse. For several days, approach to camp was blocked by rising water from nearby Lake Ferris that necessitated a detour--and moving one tent. The icebergs in the distance remained during the time the team was there, and probably through the entire summer. In November 2003, Edward S.
