Could Israel Acquire F-22 Raptors as the US Air Force Retires Them?

 

The US Air Force (USAF) plans to retire its older F-22 Raptors in 2024, deeming upgrades too costly. However, Israel, a key ally, might find value in acquiring these fifth-generation fighter jets despite upgrade expenses surpassing $2 billion. 

Unlike the widely exported F-35, the F-22 has only been operated by the US due to a 1990s Congressional ban aimed at preventing its advanced stealth technology from reaching adversaries like Russia and China.

Former President Donald Trump once considered selling the F-22 to Israel to maintain its military edge, especially after agreeing to sell F-35s to the UAE. With the USAF seeking to redirect funds from retiring Block 20 F-22s to new projects like hypersonic missile development and the Next Generation Air Dominance (NGAD) fighter, 32 out of 185 F-22s are set for storage. Despite operational costs of $485 million annually, experts argue that transferring these aircraft to Israel would bolster US allies against threats from Iran, Russia, and China.

National security analyst Brandon J. Weichert suggests that selling F-22s to Israel could help reopen production lines, reduce costs, and sustain the jet's long-term viability. The F-22, although not designed for export, offers unparalleled capabilities, as demonstrated in exercises like Northern Edge 2006, where it achieved a 108-to-zero kill ratio against top fighter jets.

Developed under the Advanced Tactical Fighter (ATF) program, the F-22 Raptor is a single-seat, twin-engine stealth fighter with superior air-to-air and ground attack capabilities. Despite its high cost and certain limitations, such as a relatively short range and small weapons magazine, the F-22 remains a formidable asset. The USAF originally planned to procure 750 units but scaled down to 187 by 2009, with the last delivery in 2012.

As the USAF considers the future of its F-22 fleet, transferring some of these aircraft to Israel could ensure the US remains strategically prepared with well-armed allies, particularly amid growing global tensions.

India to Reconsider Russian Su-57 Stealth Fighter to Counter China's J-20

 The Indian Air Force (IAF), recognized as the fourth largest air force globally, is currently without a fifth-generation fighter jet. Despite previous involvement in the Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) project, which was based on Russia's Sukhoi Su-57, India withdrew from the program in 2018. However, the possibility of revisiting this decision remains open.

Globally, 19 countries operate fifth-generation fighters. China uses its Chengdu J-20 ‘Mighty Dragon,’ while Russia employs the Sukhoi Su-57 ‘Felon.’ Seventeen other nations have adopted the Lockheed Martin F-35 Lightning II, with the U.S. exclusively operating the F-22 Raptor. Only the U.S., China, and Russia have developed original fifth-generation fighters, though many nations participate in F-35 development.

The FGFA project aimed to integrate 43 enhancements proposed by India into the Su-57, including advanced sensors and avionics. The Indian variant was planned to be a two-seater, featuring a pilot and a weapon systems operator (WSO). Since stepping away from FGFA, India has focused on developing its own fifth-generation fighter, the Advanced Medium Combat Aircraft (AMCA). However, the Su-57 remains an option, especially given the F-35's unavailability due to India's acquisition of the Russian S-400 air defense system.

The Sukhoi Su-57 is a twin-engine, stealth multirole fighter first developed in 1999 and introduced to the Russian military in 2020. Known for its air superiority and ability to engage surface and maritime targets, the Su-57 boasts stealth features, super-maneuverability, and a large payload capacity. Despite its advanced capabilities, the Su-57 has faced technological and financial hurdles, including issues with structural integrity during early tests.

The Su-57 features a blended wing body fuselage, extensive use of composites, and advanced stealth technologies aimed at reducing radar and infrared signatures. It is equipped with sophisticated avionics, including a modular avionics system and various radar systems for enhanced situational awareness. The aircraft can deploy various countermeasures and is being tested for advanced AI and unmanned teaming technologies.

Russia's production of the Su-57 has been slow, with plans for significant expansion. Initial operational use included deployments in Syria and Ukraine, demonstrating the aircraft's capabilities in combat situations. Future developments include an upgraded Su-57M variant, a potential carrier-based version, and integration with the Okhotnik UCAV for uncrewed operations.

In contrast, China’s Chengdu J-20 ‘Mighty Dragon’ has seen rapid production, with nearly 250 units built. Designed for air superiority and precision strikes, the J-20 features advanced stealth design, powerful radar systems, and high maneuverability. The J-20’s production and deployment have outpaced the Su-57, reflecting China's growing military capabilities.

India, once a partner in the FGFA project, remains cautious about fully committing to the Su-57. Given the challenges and delays in developing the AMCA, India might reconsider the Su-57 or explore other options like the Su-75 Checkmate. However, with China's expanding J-20 fleet and potential threats from neighboring countries, India must act swiftly to ensure its air force remains competitive.

The Su-57 and J-20 will likely compete for market share in regions like Africa, West Asia, and Southeast Asia. Despite their differences, both aircraft offer cost-competitive solutions for countries seeking advanced air combat capabilities. As the global landscape of fifth-generation fighters evolves, India’s decisions will significantly impact its strategic military position.

Chinese Researchers Analyze F-35 vs. F-22: Which Stealth Fighter Poses a Greater Threat to PLAAF?

 Recently, US Indo-Pacific Command's Admiral Samuel Paparo discussed a “Hellscape” strategy to counter China, predicting a strong drone force could severely challenge any Chinese invasion of Taiwan. General Kenneth Wilsbach, Commander of the Pacific Air Forces, argued in March 2022 that using expendable unmanned aircraft against China would be more effective than deploying high-end stealth fighters like the F-35s or F-22s.

While many analysts view the F-22 Raptors as the primary threat to Beijing, Chinese researchers have a different perspective. In April last year, they conducted a study comparing the US stealth fighters F-35 and F-22, concluding that the F-35 Lightning II presents a greater threat than the F-22 Raptors.

Despite the F-22’s reputation as a formidable stealth aircraft, the study published in the Chinese-language journal Modern Defense Technology found the F-35 poses a more significant threat to Chinese military defenses. The research evaluated the impact of these aircraft during various stages of a counter-air operation near China’s coastline.

The study suggests that the F-35A, with its advanced avionics and multirole capabilities, is more adaptable and effective in potential conflicts in the Indo-Pacific region. Researchers noted that the F-35's ability to perform multiple functions and its versatility in various missions give it an edge over the F-22.

The F-35 has become a vital asset in the region due to its advanced technology and remarkable adaptability. The US and its allies operate many F-35s near China, whereas the F-22s are fewer in number and solely operated by the US Air Force, often on a rotational basis. By 2035, over 300 F-35s are expected to be deployed in the Indo-Pacific, with operators including Australia, Japan, Singapore, South Korea, and the US.

To counter the F-35 threat, Bao Junchen from the National University of Defense Technology and a team from the People’s Liberation Army’s Unit 31649 in Guangdong propose a dual strategy. They recommend enhancing electronic warfare capabilities for "soft kill" actions and developing physical weapons for "hard kill" responses. The F-35A's roles as both an intelligence-gathering sensor and a primary escort for forward attacks call for both non-destructive and destructive countermeasures.

China views the US’s penetrating counter-air operation strategy as a significant threat and is heavily investing in military capabilities to counteract US power in the Asia-Pacific. The US maintains a strong military presence in the region, with bases in Japan, South Korea, and Guam. In response, China has deployed advanced systems like the HQ-9 missile system and the J-20 stealth fighter, increasing production of the latter.

These weapons are intended to counter US air defenses and target high-value assets such as airfields and command centers. The study emphasizes that analyzing the F-22 and F-35 can help China develop effective countermeasures and protect its airspace. Additionally, the research advocates for a coordinated strategy to counter B-2 and B-1B bombers, which pose a threat when penetrating deeper into Chinese territory. A multi-dimensional approach using various platforms from air, land, sea, and space is recommended.

Although the study found the MQ-9 drone less threatening, it warned against ignoring advanced drones like the XQ-58A and RQ-180. The researchers used an analytic hierarchy process (AHP) to evaluate each aircraft’s threat level, offering a nuanced assessment. However, the lack of raw data due to military sensitivity makes independent verification challenging.

US Admiral Reveals “Hellscape” Drone Warfare Strategy to Counter China’s Taiwan Invasion Plan

 

The United States is developing a strategy to deploy a vast array of drones to counter a potential Chinese invasion of Taiwan. This plan, referred to as the "Hellscape" strategy, aims to use drones to overwhelm and distract Chinese forces, buying crucial time for US and allied forces to mount a full-scale response.

Admiral Samuel Paparo, the commander of US Indo-Pacific Command, outlined this approach at the International Institute for Strategic Studies’ Shangri-La Dialogue Summit. The strategy involves deploying thousands of unmanned submarines, surface ships, and aerial drones as soon as China’s invasion fleet begins crossing the 100-mile Taiwan Strait.

China recently conducted military drills following the inauguration of Taiwan’s new president, intensifying its calls for reunification with Taiwan. US President Joe Biden has hinted at military support for Taiwan in the event of an invasion, which could escalate into a larger US-China conflict involving Washington's regional allies. This makes it essential for the US to develop effective countermeasures against Chinese forces in the Taiwan Strait.

The "Hellscape" strategy heavily relies on autonomous systems, a tactic influenced by the recent war in Ukraine. In Ukraine, drones have been used to launch strikes on control centers, refineries, airfields, and ships, demonstrating that modern air defenses are not impenetrable. This has reshaped how militaries approach modern warfare, with a focus on cost-effective, reusable, and disposable drone technology.

General Kenneth Wilsbach, Commander of the Pacific Air Forces, initially proposed using "attritable" unmanned aircraft against China instead of high-end stealth fighters like the F-35s or F-22s. These lower-cost, disposable drones would serve as decoys, gradually wearing down Chinese defenses by creating numerous targets.

The Pentagon is actively working on this drone warfare strategy, planning to spend $1 billion on the Replicator program this fiscal year. This program aims to rapidly scale and deploy thousands of autonomous systems within the next 18 to 24 months, utilizing AI, robotics, and commercial technology. The Pentagon is also collaborating with defense partners to develop and procure these critical systems.

Deputy Secretary of Defense Kathleen Hicks emphasized the need to counter China’s mass with a mass of drones that are more challenging to target. The US Navy is also working on developing swarming drones, including underwater drones, to counter the numerical superiority of the Chinese PLA Navy in the Indo-Pacific region.

Admiral Paparo highlighted the strategic advantage of US unmanned capabilities, stating that these systems would amplify US advantages in the region. He noted that recent Chinese military drills appeared to be rehearsals for a Taiwan invasion, which the US observed and learned from.

In response to these developments, China has expressed dissatisfaction. The state-owned Global Times criticized the US strategy, suggesting it was a desperate attempt to maintain its dominance and incite Taiwan’s independence efforts.

Chinese Satellite Tracks US F-22 Raptor: A Potential Shift in Aerial Surveillance Capabilities

 Chang Guang, a Chinese commercial aerospace company, has released a brief video purportedly showing a satellite tracking a US F-22 Raptor fighter jet. The video, which dates back to 2020, was shared by Clash Report on X and reportedly utilizes the commercial Jilin-1 remote control satellite system.

The footage is notably short, lasting just six seconds, during which the satellite’s camera tracks the aircraft, identified as an American F-22 Raptor navigating through partly cloudy skies. This raises several questions: Is the aircraft truly an F-22? Was the video edited? Did the Jilin-1 satellite system actually perform the tracking? And why release only a brief segment?

While observing the F-22 in video footage isn't unusual, its stealth technology makes it nearly invisible to radar but not to the naked eye. If the satellite can track the F-22 beyond these six seconds, it suggests a significant advancement in combat capabilities, implying that satellites could detect aircraft that ground-based radars might miss.

Reports confirming that Chinese satellites tracked an F-22 flight would spark discussions on combat capabilities. Stealth planes like the F-22 are not completely invisible to radars but have "low observability," making them harder to detect. The F-22’s radar cross-section (RCS) is about 0.0001 m², akin to a small metallic pebble, making it detectable at 1/17.5 of the distance of a typical fighter jet. However, detection depends greatly on the viewing angle.

While the F-22’s radar signature is minimal, it is still detectable, meaning tracking a known stealth aircraft is feasible. This suggests that integrating orbital technology with ground stations could enhance radar focus on specific sectors, aiding in identifying stealth aircraft signatures, assuming clear skies and no interference.

China’s Jilin-1 Satellite System, developed by Chang Guang Satellite Technology Co., Ltd., is a constellation of commercial remote sensing satellites providing high-resolution imagery and video for applications such as environmental monitoring, urban planning, and disaster response. It features diverse satellite types, including optical imaging, video, and hyperspectral satellites, allowing for a wide range of data capture. With a high revisit frequency, the system provides frequent updates of the same geographic area, crucial for real-time monitoring.

Launched initially in 2015, the Jilin-1 constellation has expanded significantly and now includes dozens of satellites, with plans for further growth.

Footage from 2020 has revealed that Chinese engineers are working on an advanced AI system to enhance the capabilities of low-cost commercial satellites, potentially transforming them into powerful surveillance tools. Reports suggest this system could improve success rates by up to seven times compared to current technology. Developed by researchers in the Chinese military, this AI system claims to track moving objects as small as a car with remarkable precision, achieving 95% accuracy in identifying small objects in Jilin-1 satellite videos, significantly surpassing existing methods.

US Navy Boosts China Surveillance with Second MQ-4C Triton Deployment to Okinawa

 

The US Navy has significantly increased its surveillance capabilities in the Asia-Pacific region by deploying a second MQ-4C Triton maritime surveillance aircraft to Japan’s Kadena Air Base in Okinawa. This move follows the earlier deployment of several MQ-9 Reaper drones, enhancing intelligence gathering in the area.

According to an official from Japan’s Ministry of Defense, the second Triton arrived at Kadena Air Base at 3:40 p.m. on June 9. This follows the first MQ-4C Triton’s arrival on May 20, both temporarily relocated from Guam. Japanese media images show both aircraft stationed in the Navy's tarmac hangar shortly after the second aircraft's arrival.

The Tritons will be stationed at Kadena from May to October, supported by approximately 50 personnel. Since October, eight MQ-9 Reaper drones have also been deployed at Kadena, highlighting the base's critical role due to its strategic location, within three hours' flight time from Beijing, Seoul, and Taipei.

Kadena Air Base, the largest US Air Force base in the Asia-Pacific region, regularly hosts advanced fighter jets, with recent rotations including F-35 Lightning IIs, F-22 Raptors, US F-16s, and F-15E Strike Eagles. The base is also increasing its unmanned aerial vehicle presence to bolster reconnaissance and surveillance efforts.

The Okinawa Times, referencing the Federal Aviation Administration (FAA), reported that the second MQ-4C Triton was scheduled for a flight around Okinawa’s main island on June 9. However, this plan was withdrawn shortly after the aircraft's arrival.

The deployment has sparked controversy, with local governments and the Okinawa Prefecture opposing the indefinite presence of MQ-9 drones and the temporary deployment of MQ-4C Tritons. The Kadena Town Council expressed concerns about potential aircraft accidents due to the rising number of US military assets at the base.

The MQ-4C Triton, developed by Northrop Grumman, is distinct from the RQ-4 Global Hawk, designed to withstand bird strikes and lightning, and capable of close-range maritime observation. Equipped with advanced sensors, the Triton can provide precise targeting information to naval assets, enhancing operational reach.

With two MQ-4C Tritons now operational at Kadena, the US military is set to intensify surveillance in regions where China is increasingly active. Drones will undertake intelligence missions in the Nansei region and surrounding areas, crucial maritime territories stretching from Kyushu to Taiwan.

China has escalated maritime challenges in the East and South China Seas, with frequent coast guard incursions into Japanese-claimed waters around the Senkaku Islands. Japan views these actions as attempts to undermine its sovereignty over the islands. The enhanced surveillance capabilities provided by the drones are crucial for monitoring and asserting control over these contested areas without provocation.

Boeing Delivers Two New F-15EX Eagle II Jets to US Air Force Amid Modernization Delays

 On June 6, Boeing delivered two new F-15EX Eagle II fighter jets to the United States Air Force (USAF), designated as EX7 and EX8. These aircraft are set to join the 142nd Airlift Wing, which is part of the Oregon Air National Guard’s Redhawks. With this delivery, the USAF now has six F-15EX aircraft. The Air Force plans to acquire a total of 104 fighters from Boeing, up from the initially planned 80, to replace the aging F-15C/D Eagle fleet and support the F-22 Raptor and F-35A Lightning II fleets.

The modernization of the F-15EX has encountered significant delays due to manufacturing and quality issues identified in the fuselage and cabin assembly since June 2023. The Government Accountability Office has reported that these problems could delay the F-15EX program by up to six months, affecting the US's ability to deploy airpower overseas. For example, the retirement of F-15C/D Eagles left 48 positions vacant at the US Air Force base in Okinawa, disrupting strategic plans. In response, the USAF relocated some F-22 Raptors from Joint Base Pearl Harbor-Hickam in Hawaii and deployed F-16 aircraft. Additionally, two National Guard squadrons in Japan have increased their presence in the region.

The delivery delays also impact foreign customers like Israel, which has requested expedited delivery due to its ongoing conflict with Hamas. Earlier this year, Israel requested a new squadron of 25 F-15EX fighters, an additional squadron of F-35I fighters, and a squadron of AH-64E Apache helicopters to bolster its military capabilities.

The F-15EX Eagle II is an advanced variant of the F-15 fighter, designed to replace older F-15C/D models. It features enhanced avionics, increased payload capacity, and modernized systems for superior performance in contemporary combat scenarios. The aircraft measures approximately 63.8 feet in length, with a wingspan of 42.8 feet and a height of 18.5 feet. Its maximum takeoff weight is about 81,000 pounds, making it one of the most robust fighters in the USAF.

Powered by two Pratt & Whitney F100-PW-229 engines, each producing 29,000 pounds of thrust with afterburners, the F-15EX can exceed speeds of Mach 2.5 and offers exceptional maneuverability. It includes an advanced fly-by-wire control system, a digital cockpit with large-area displays, and an open mission systems architecture for rapid integration of new technologies.

The avionics suite features the Raytheon AN/APG-82[V]1 AESA radar for superior detection and tracking, and the Joint Helmet Mounted Cueing System (JHMCS) for enhanced situational awareness and targeting. The aircraft is equipped with the Eagle Passive/Active Warning and Survivability System (EPAWSS) for electronic warfare, and the Advanced Display Core Processor II (ADCP II) for high-speed data processing and mission management.

In terms of armament, the F-15EX can carry a wide range of weapons, including air-to-air missiles like the AIM-120 AMRAAM and AIM-9X Sidewinder, as well as air-to-ground munitions such as JDAM and Small Diameter Bomb (SDB). It also has an internal M61A1 Vulcan 20 mm cannon for close-in combat.

The operational range of the F-15EX is about 1,200 nautical miles without refueling, which can be extended significantly through aerial refueling, allowing it to perform long-range missions and maintain a persistent presence in contested areas.

US Military Expands Stealth Technology for Bombers, AEW&C, and Support Aircraft

 

On May 22, 2024, the US Air Force (USAF) unveiled the first official photos of the B-21 Raider stealth bomber in flight, following its inaugural flight last year. Northrop Grumman, the manufacturer, released additional images showcasing the bomber's takeoff, flight, and presence at Edwards Air Force Base. The B-21 Raider joins the B-2 Spirit as the only active stealth bombers, with China's Xi’an H-20 expected by 2025 and Russia's Tupolev PAK DA by 2027. These aircraft represent the forefront of heavy stealth technology.

Stealth Technology Overview Stealth technology involves integrating various low-observable (LO) technologies to significantly reduce an aircraft's detectability. This includes minimizing radar cross-section (RCS), acoustic signature, thermal imprint, and other detectable attributes. The term "stealth" became widely known in the late 1980s with the F-117 stealth fighter's deployment during the 1991 Gulf War.

Key techniques include tilting or removing vertical stabilizers, applying radar-absorbing materials (RAM) to leading edges, and internalizing weapons and fuel tanks. Advanced materials and coatings, such as dielectric composites and transparent conductors for cockpit canopies, further reduce radar reflections. Placing engines within the wing or fuselage reduces infrared signatures, and passive infrared and low-light TV sensors help maintain stealth by avoiding active emissions.

Operational Use of Stealth Technology Stealth technology saw its first operational use with the F-117 in the Gulf War, later deployed in Yugoslavia, Iraq, Afghanistan, and Libya. Stealth helicopters, like the modified Sikorsky UH-60 Black Hawk used in the 2011 Osama bin Laden raid, also utilized stealth features. More recent combat applications include the F-22 over Syria and the Israeli F-35I in Syrian and Iranian airspace.

Limitations and Countermeasures Despite its advantages, stealth technology has limitations. Low-frequency radars can detect stealth aircraft, though with reduced accuracy. Infrared search and track (IRST) systems can detect aircraft heat signatures. Stealth design involves trade-offs in aerodynamics, development time, and cost, often requiring larger internal bays and specific maintenance procedures. Additionally, counters to stealth technology continue to evolve.

Stealth Aircraft Developments The B-2 Spirit, produced from 1987 to 2000, remains the only operational stealth bomber, with a wingspan of 172 feet and a maximum takeoff weight of 170,600 kg. The new B-21 Raider, smaller and estimated at $700 million per unit, aims to replace the aging B-2 fleet. The USAF plans to invest $203 billion over 30 years to develop and operate at least 100 B-21s. China's H-20 and Russia's PAK DA are still in development, with limited details available.

Future of Stealth Technology The USAF's plans include stealthy flight refueling aircraft (FRAs) to support closer refueling of stealth fighters and bombers in contested environments. Lockheed Martin's Skunk Works has proposed concepts for stealth tankers, and Boeing's MQ-25 Stingray is in development as a stealth refueling drone.

Stealth AEW&C aircraft, such as the Boeing E-7 Wedgetail, aim to reduce detectability through design modifications. Future stealth initiatives may also encompass cargo and special operations aircraft, with flying wing designs offering potential solutions for stealth transport.

Innovative Stealth Concepts Emerging technologies, such as metasurfaces and plasma stealth, promise further advancements in RCS reduction. Adaptive aero-elastic wings and fluidic controls are also under exploration, though these remain costly and in developmental stages.

Overall, the USAF's investment in stealth technology for various aircraft ensures continued global dominance and operational effectiveness in increasingly contested environments.

China’s J-20 Stealth Fighter Continually Upgraded, New Next-Gen Aircraft Imminent

 Following displays of air power against Taiwan and India, a pilot from the Chinese People’s Liberation Army Air Force (PLAAF) announced that the J-20 Mighty Dragon is undergoing continuous upgrades to meet its combat objectives.

The Global Times, a state-owned publication, reported that a top test pilot of the J-20 stealth fighter jet revealed that the aircraft is receiving ongoing upgrades, with a next-generation warplane expected to debut soon. Test pilot Li Gang, speaking on China Central Television (CCTV), stated, "The J-20 is constantly improving, keeping pace with the times, and continuously perfecting its mission system to achieve its expected combat objectives."

Li hinted at the imminent introduction of a new aircraft, though he did not specify its type. China is known to be developing a sixth-generation fighter, similar to the efforts of the US and Europe.

In February 2023, the Aviation Industry Corporation of China (AVIC) shared a concept for a sixth-generation fighter featuring diamond-shaped wings and a tailless design. However, as reported by EurAsian Times, China is still working on improving basic radar, avionics, and engine technologies.

Chinese commentators emphasized that China would not rest on the success of the J-20 while other nations, like the US, are developing next-generation fighter jets. The US is progressing with the Next Generation Air Dominance (NGAD) system.

While a new Chinese aircraft might be years away, the J-20 has become a key asset for the PLAAF, deployed in all five military theaters. It has been stationed near the contentious border with India and has participated in military drills targeting Taiwan, demonstrating its readiness for future combat scenarios.

Chinese military aviation specialist Fu Qianshao highlighted that China's aviation technologies have advanced rapidly since the J-20's initial test flight. While some have doubted the J-20's stealth capabilities, Fu stressed that it incorporates the latest technologies, including new engines and aerodynamic, avionics, radar, software, and material modifications.

Fu compared the J-20 to the US Air Force's F-22 Raptors, noting that the F-22 has not seen significant updates since its development and is aging. He argued that the J-20 is currently the most advanced fighter jet globally.

Although the F-22 has received upgrades, particularly in the Block 30/35 versions, the J-20's continuous enhancements highlight China's commitment to advancing its stealth fighter capabilities. The J-20's upgrades include potentially increasing its missile capacity, adding thrust-vectoring engine nozzles, and installing higher-thrust WS-15 engines for supercruise capability.

Additionally, a twin-seater J-20 model, possibly for autonomous escort control, is in development. This model might also serve as a tactical electronic jammer and advanced early warning aircraft.

Reports suggest that the J-20 could have an edge over the F-22 due to its ability to carry multiple missiles like the PL-15, which may have a longer range than the US AIM-120 AMRAAM.

As tensions rise between the US and China, the J-20 poses a significant challenge to US air superiority. With around 200 J-20 fighters in service and more in production, the J-20 represents a formidable threat to the US and its allies.

Global Advances in Sixth-Generation Fighter Jets: Emerging Technologies and International Collaboration

 Most fighter jets in service worldwide belong to the 4th and 4.5th generations, with over 1,500 fifth-generation fighters currently operational. Numerous fifth-generation aircraft programs are now integrating sixth-generation technologies, which are still developing and are expensive due to their cutting-edge nature. These advancements include enhanced communications, Internet of Things (IoT) capabilities, and extensive data sharing across platforms. A global look at the efforts to develop sixth-generation fighter aircraft reveals various international collaborations.

Many nations, unable to fund these expensive programs independently, are forming consortiums. The F-35 program exemplifies such partnerships. Some countries aim to enhance their defense industries and reduce reliance on American programs. The Global Combat Air Program (GCAP), involving Italy, Japan, and the UK, is a notable example.

The term "generation" in jet fighters refers to stages in design, performance, and technological evolution, though there are no official definitions. Understanding the fifth and sixth generations is crucial.

Fifth-Generation Fighters: The fifth generation began with the F-22 Raptor in 2005, designed for a network-centric combat environment. These fighters have advanced low-observable features, multifunction AESA radars, and integrated sensors for superior situational awareness. Key features include advanced electronic warfare systems, stealth technology, thrust vectoring for enhanced maneuverability, and internal weapon bays to maintain low radar visibility. Examples include the F-35, Russia's SU-57, and China's Chengdu J-20 and Shenyang J-31.

Sixth-Generation Technologies: These include advanced networking, AI, data fusion, cyber warfare capabilities, and modular designs allowing rapid upgrades. New stealth airframes, high-capacity networking, and integration with various platforms are expected. The Tempest program, led by the UK, Italy, and Sweden, exemplifies these technologies, including AI-supported operations and advanced radar systems.

Global Collaborations: The GCAP aims to merge efforts from the UK, Japan, and Italy to develop a sixth-generation fighter, combining the BAE Systems Tempest and Mitsubishi F-X programs. Development is set to start in 2025, with service induction around 2035. Challenges include harmonizing capabilities across partner nations and ensuring cost-effectiveness.

US NGAD Program: The USAF's Next Generation Air Dominance (NGAD) program aims to succeed the F-22 Raptor with a family of systems, including manned and unmanned aircraft, expected to be operational by the 2030s.

Chinese and Russian Programs: China is advancing its sixth-generation aircraft development, aiming for completion by 2035. Russia, despite the incomplete operationalization of the Su-57, is also pursuing sixth-generation technology, emphasizing AI and automation.

Overall, the development of sixth-generation fighter jets is marked by international collaboration, cutting-edge technology integration, and the aim to maintain air superiority in future combat environments.

JSF may miss acceleration Goals

The F-35 Lightning II’s transonic acceleration may not meet the requirements originally set forth for the program, a top Lockheed Martin official said.

“Based on the original spec, all three of the airplanes are challenged by that spec,” said Tom Burbage, Lockheed’s program manager for the F-35. “The cross-sectional area of the airplane with the internal weapons bays is quite a bit bigger than the airplanes we’re replacing.”

The sharp rise in wave drag at speeds between Mach 0.8 and Mach 1.2 is one of the most challenging areas for engineers to conquer. And the F-35’s relatively large cross-sectional area means, that as a simple matter of physics, the jet can’t quite match its predecessors.

“We’re dealing with the laws of physics. You have an airplane that’s a certain size, you have a wing that’s a certain size, you have an engine that’s a certain size, and that basically determines your acceleration characteristics,” Burbage said. “I think the biggest question is: are the acceleration characteristics of the airplane operationally suitable?”

A recent report by the Defense Department’s top tester, J. Michael Gilmore, says that the Navy’s F-35C model aircraft, which has larger wing and tail surfaces, is not meeting requirements for acceleration.

The report doesn’t say whether the F-35A and F-35B have hit similar snags.

Richard Aboulafia, an analyst with the Teal Group, Fairfax, Va., said that the revelation was not particularly surprising.

“It’s a strike fighter,” Aboulafia said. “It’s not an interceptor; it’s not an F-22.”

Aboulafia said it was unclear whether additional engine power could boost acceleration in the difficult transonic regime. So far, doubts about the aircraft’s aerodynamic performance haven’t diminished Lockheed’s sales prospects, he said.

The F-35 transonic acceleration specifications were written based on clean-configuration F-16 Fighting Falcon and F/A-18 Hornet fighter, Burbage said.

But unlike the Hornet or the F-16, the F-35 has the same configuration unloaded as it does loaded with weapons and fuel, Burbage said. When an F/A-18 or F-16 is encumbered with weapons, pylons and fuel tanks, those jets are robbed of much of their performance.

“What is different is that this airplane has accelerational characteristics with a combat load that no other airplane has, because we carry a combat load internally,” Burbage said, the F-22 Raptor notwithstanding.

Even fully loaded, the F-35’s performance doesn’t change from its unencumbered configuration, he said.

In the high subsonic range between Mach 0.6 to Mach 0.9 where the majority of air combat occurs, the F-35’s acceleration is better than almost anything flying.

Thus far, Lockheed has not had issues with the plane’s acceleration, Burbage said. There are top level Key Performance Parameters from which lower level detailed engineering specification are derived and Lockheed’s job is to meet as many of those specifications as possible within the laws of physics, he said. Discussions are underway about if those original specifications are relevant given the jet’s acceleration in a combat configuration, Burbage added.

Air Force Lt. Col. Eric Smith, director of operations at the 58th Fighter Squadron at Eglin Air Force Base, Fla., and F-35 test pilot, said that flying the aircraft is a thrilling experience.

“I can’t even explain the adrenaline rush you get when you light the afterburner on that thing,” Smith said. “The acceleration is much better than an F-16.”

But the F-35’s aerodynamic performance is not what makes the jet special, Smith said. The F-35 powerful sensors and data-links and how that information is fused into a single coherent and easy to use display are what will make the jet an effective warplane.

Burbage added that while the F-35 is designed as a supersonic fighter, it’s not optimized for the extremely high supersonic speeds that the Raptor was designed to operate at.

“This is not a supercruising airplane like the F-22,” Burbage said.
