Special: F-35 vs China J-31 & Russia PAK-FA

KRIS OSBORN

An F-35 fighter pilot says he would be confident flying the Joint Strike Fighter against any enemy in the world, including Russian and Chinese 5th Generation stealth fighters.

An F-35 Joint Strike Fighter would be able to use its sensors, weapons and computer technology to destroy Russian and Chinese 5th-Generation Stealth fighters in a high-end combat fight, service officials said.

“There is nothing that I have seen from maneuvering an F-35 in a tactical environment that leads me to assume that there is any other airplane I would rather be in. I feel completely comfortable and confident in taking that airplane into any combat environment,” Lt. Col. Matt Hayden, 56th Fighter Wing, Chief of Safety, Luke AFB, Arizona, told Scout Warrior in a special pilot interview.

Furthermore, several F-35 pilots have been clear in their resolve that the multi-role fighter is able to outperform any other platform in existence.

Hayden was clear to point out he has not, as of yet, flown simulated combat missions against the emerging Russian Sukhoi T-50 PAK FA 5th-Generation stealth fighter now in development or the Chinese Shenyang J-31 5th Generation Stealth aircraft. While he said he did not personally know all of the technologies and capabilities of these Russian and Chinese aircraft, he was unambiguous in his assertion regarding confidence in the F-35. 

Available information says the Russians have built at least 6 prototype T-50 PAK FAs for their Air Force and Navy; the Chinese conducted a maiden test flight of its J-31 in 2012. In addition, China is in pre-production with its J-20 5th-Generation stealth fighter. This fighter, called the Chengdu J-20, made its first flight in 2011, and is expected to be operational by 2018, according to publicly available information and various news reports.

While Hayden did not elaborate on aspects of the J-20, he did say he would be confident flying the F-35 against any aircraft in the world.

“All those other countries (Russia and China) are trying to develop airplanes that are technologically capable as well -- from an F-35 perspective. We are no less capable than any airplane and any fighters out there,” Hayden described. 

In addition to leveraging the best available technologies on a fighter jet, winning a dog-fight or combat engagement would depend just as much on the air-tactics and decisions made by a pilot, Hayden explained.

“I have not flown against some of those aircraft. When you fight against an airplane, it depends upon the airspeed. If I maximize the effectiveness of an F-35, I can exploit the weaknesses of any other aircraft,” he said.

Many analysts have made the assessment that the J-20 does appear to be closely modelled after the F-35.

In fact, a Defense Science Board report, cited in a 2014 Congressional assessment of the Chinese military, (US-China Economic Security and Review Commission) makes reference to specific developmental information and specs of numerous U.S. weapons systems believed to be stolen by Chinese computer hackers; design specs and technologies for the F-35 were among those compromised by Chinese cyber-theft, according to the report.

An AIN Online report from the Singapore Air Show in February of this year catalogues a number of J-20 features and technologies – including those believed to be quite similar to the F-35.

Chinese 5th-Generation


“The J-20 is a large multi-role fighter with stealthy features similar to those found in the American F-22 and F-35. Although very little is known about its intended purpose, the aircraft appears to offer capability in a number of roles, including long-range interception and precision attack.

In terms of weapon carriage the J-20 has a similar arrangement to that of the Lockheed Martin F-22, comprising two lateral bays for small air-to-air missiles such as the agile, imaging-infrared PL-10, and a large under-fuselage bay for accommodating larger missiles and precision-guided surface attack weapons. The 607 Institute’s new PL-15 active-radar missile is thought to be the primary long-range air-to-air weapon, reportedly having been test-fired from a Shenyang J-16 platform last year. The PL-21, a ramjet-powered weapon in the same class as the MBDA Meteor, is another possibility for the J-20.

The sensor suite includes an electro-optical targeting system (EOTS) and a large-array AESA radar, which was developed by the 14th Institute at Nanjing Research Institute of Electronics Technology (NRIET, 14th Institute), and is possibly designated Type 1475/KLJ-5. Diamond-shaped windows around the fuselage suggest that a distributed aperture infrared vision system is installed.


In the cockpit, the J-20 sports three large color displays, plus other small screens, and a holographic wide-angle head-up display. An advanced datalink has been developed, and a retractable refueling probe is located on the starboard side of the forward fuselage. Much of the avionics suite has been tested by the CFTE (China flight test establishment) aboard a modified Tupolev Tu-204C, in much the same way as the systems of the F-22 were tested in a Boeing 757.”

Regarding the Russian T-50 PAK FA Stealth fighter, numerous reports suggest the aircraft has numerous technological problems and is a 5th generation plane “in name only.”

Russian 5th-Generation 

The Following is a report on the T-50 PAK FA from Business Insider, also from this year’s Singapore Air Show….Business Insider Report HERE

“Reporting from the Singapore Airshow 2016, IHS Jane's reports that "Russian industry has consistently referred to the Sukhoi T-50 PAK FA as a fifth-generation aircraft, but a careful look at the program reveals that this is an 'in name only' designation."

This is largely because of a lack of evolutionary technology aboard the plane compared with previous jets that Russia and the US have designed. Indeed, the PAK FA's engines are the same as those aboard Russia's 4++ generation (a bridging generation between fourth- and fifth-generation aircraft) Su-35. Additionally, the PAK FA and the Su-35 share many of the same onboard systems.

And even when the PAK FA's systems are different from the Su-35's, the plane's specifications are still not up to true fifth-generation standards.

RealClearDefense, citing Indian media reports that are familiar with a PAK FA variant being constructed in India, notes that the plane has multiple technological problems. Among these problems are the plane's "engine performance, the reliability of its AESA radar, and poor stealth engineering."

F-35 Sensor Fusion

Despite various reports about technologies being engineered into the Russian and Chinese 5th-Generation Stealth Fighters, it is in no way clear that either aircraft is in any way comparable to the F-35. Most publicly available information seems to indicate that the F-35 is superior - however, to some extent, the issue remains an open question. More information is likely to emerge once the Russian and Chinese aircraft are operational and deployed. 

For example, the Chinese J-20 is cited as having an Electro-Optical targeting system, stealth configuration, datalink, AESA radar and precision weaponry quite similar to the F-35, according to the AIN report. 

The computer algorithms woven into the F-35 architecture are designed to leverage early iterations of what could be described as early phases of “artificial intelligence.” Broadly speaking, artificial intelligence refers to fast-evolving computer technology and processors able to gather, assess and integrate information more autonomously in order to help humans make decisions more quickly and efficiently from a position of command-and-control.

“If there is some kind of threat that I need to respond to with the airplane, I don’t have to go look at multiple sensors and multiple displays from multiple locations which could take my time and attention away from something else,” Hayden added.

The F-35 software, which shows images on display screens in the cockpit as well as on a pilot's helmet-mounted-display, is able to merge results from various radar capabilities onto a single screen for the pilot.


“The F-35 takes from multiple sensors around the airplane and combines them together in a way that is much more manageable and accessible -- while not detracting from the other tasks that the pilot is trying to accomplish,” Hayden said.

For instance, the F-35's Electro-Optical Target System, or EOTS, is an infrared sensor able to assist pilots with air and ground targeting at increased standoff ranges while also performing laser designation, laser range-finding and other tasks.

In addition, the plane's Distributed Aperture System, or DAS, is a series of six electro-optical sensors also able to give information to the pilot. The DAS includes precision tracking, fire control capabilities and the ability to warn the pilot of an approaching threat or missile.

The F-35 is also engineered with an Active Electronically Scanned Array Radar, which is able to track a host of electromagnetic signals, including returns from Synthetic Aperture Radar, or SAR. This paints a picture of the contours of the ground or surrounding terrain and, along with Ground Moving Target Indicator, or GMTI, locates something on the move on the ground and airborne objects or threats.

Hayden added that the F-35 has been training against other F-35s in simulated combat situations, testing basic fighter maneuvers. Having himself flown other fighter aircraft, he explained that many other F-35 pilots also fly the airplane after having experience flying an F-16, A-10 or other combat aircraft.

“The F-35’s low-observable technology can prevent detection. That is a strength that other airplanes do not have,” he said.

F-35 and F-22

At the same time, senior Air Force leaders have made the point that F-35 technological superiority is intended to be paired with the pure air-to-air dogfighting ability of the service’s F-22 – a stealth aircraft, with its speed, maneuverability and thrust-to-weight ratio, is believed by many to be the most capable air-to-air platform in the world.

“Every airplane has flaws. When you design an airplane, you design an airplane with tradeoffs - give something else up. If I was flying against an adversary in actual combat, my job would be to exploit the enemy weakness and play to my strength. I can compensate for certain things,” Hayden explained. “There is a certain way to fly and fight in an airplane, using airspeed to maximize the turning performance of the airplane.” 

During a public speech in 2015, the Air Forces Air Combat Commander, Gen. Hawk Carlisle, said the F-22 is engineered such that it can complement the F-35.

“You will use the F-35 for air superiority, but you will need the raptors to do some things in a high-end fight to penetrate denied airspace,” he said. “The airplane is designed for multi-role capability, electronic warfare and sensors. The F-35 will win against any fourth-generation airplane -- in a close-in fight, it will do exceedingly well. There will be a combination of F-22s and F-35s in the future.”


Hayden further elaborated upon these claims, arguing that the F-35 has another set of strategic advantages to include an ability to use internally built sensors. This prevents the need to use external pods on a fighter jet which can add drag, slowing down and restricting maneuverability for an aircraft.

“As an F-35 pilot, I can carry bombs to a target area where I can now take out air-to-ground threats. You have to look at the overall picture of the airplane. The airplane was designed to overwhelm the battlespace in a non-permissive threatening environment where 4th-gen fighters are not going to persist,” he added.

The F-35 is engineered with a 25-mm gun and has the ability to carry and fire a wide range of weapons. The aircraft has already demonstrated an ability to fire an AMRAAM (Advanced Medium Range Air to Air Missile), JDADM (Joint Direct Attack Munition) or GBU 12 (laser-guided aerial bomb), and AIM 9X Sidewinder air-to-air missile.

So-called "Block 3F" software for the F-35 increases the weapons delivery capacity of the JSF as well, giving it the ability to drop a Small Diameter Bomb and 500-pound JDAM.


As a multi-role fighter, the F-35 is also engineered to function as an intelligence, surveillance and reconnaissance platform designed to apprehend and process video, data and information from long distances. Some F-35 developers have gone so far as to say the F-35 has ISR technologies comparable to many drones in service today that are able to beam a “soda straw” video view of tactically relevant combat locations in real time.

Finally, regarding dogfighting, it is pertinent to point out a “War is Boring” report from 2015 which cited an F-35 fighter pilot explaining how an F-16 was able to win a “mock dogfight” against an F-35; the F-35 Joint Program Office disputed this claim, saying the F-35 used in the scenario was in no way representative of today’s operational F-35s. The software, weapons and sensor technologies used in the mock dogfight were not comparable to the most evolved F-35.

Furthermore, F-35 proponents maintained that the aircraft’s advanced computer technology and sensors would enable it to see and destroy enemy fighters from much longer ranges – essentially destroying enemy fighters before they are seen. 

OODA Loop

The idea is to enable F-35 pilots to see and destroy enemies in the air, well in advance of a potential dogfight scenario. This can be explained in terms of a well-known Air Force strategic concept pioneered years ago by air theorist and pilot Col. John Boyd, referred to as the "OODA Loop," --- for observe, orient, decide and act. The concept is to complete this process quickly and make fast decisions while in an air-to-air dogfight -- in order to get inside the enemy's decision cycle, properly anticipate, and destroy an enemy before they can destroy you.

The F-35 is designed with long-range sensors and data fusion technologies such that, as a fifth-generation aircraft, it can complete the OODA Loop much more quickly than potential adversaries, F-35 advocates claim.

Mission Data Files

Described as the brains of the airplane, the mission data files are extensive on-board data systems compiling information on geography, air space and potential threats in known areas of the world where the F-35 might be expected to perform combat operations, Air Force officials explained.

Consisting of hardware and software, the mission data files are essentially a database of known threats and friendly aircraft in specific parts of the world. The files are being worked on at a reprogramming laboratory at Eglin Air Force Base, Fla., Air Force officials toldMilitary.com last year. The mission data files are designed to work with the aircraft's Radar Warning Receiver engineered to find and identify approaching enemy threats and hostile fire. 

The mission data packages are loaded with a wide range of information to include commercial airliner information and specifics on Russian and Chinese fighter jets. For example, the mission data system would enable a pilot to quickly identify a Russian MiG-29 if it were detected by the F-35’s sensors.

The mission data files are being engineered to adjust to new threat and intelligence information as it emerges. For instance, the system is engineered to one day have all the details on a Chinese J-20 stealth fighter or Russian T-50 PAK FA stealth aircraft.

As a high-visibility, expensive acquisition program, the F-35 has many vocal detractors and advocates; the aircraft has, to be sure, had its share of developmental problems over the years. some of these problems include complications with its main computer system, called ALIS, and a now-corrected engine fire aboard the aircraft. Overall, most critics have pointed to the program's growing costs, something program officials claim has vastly improved through various money-saving initiatives and bulk-buys.
