523: CHINA: CHALLENGES IN DEVELOPING NEXT-GENERATION FIGHTER ENGINES

My Article published on The EurasionTimes Website on 22 Oct 24.

China’s defence policies underscore its commitment to self-reliance and the relentless pursuit of advanced technology development, aiming to reduce dependence on foreign sources. The country’s defence industry, a critical component of its national strategy, stands as one of the largest and most advanced in the world. It is a testament to China’s significant investments in military modernisation and technological innovation, bolstering military readiness and asserting its global influence. The roots of China’s defence industry can be traced back to the 1950s, following the establishment of the People’s Republic of China. Over the decades, it has evolved from focusing on basic weaponry to a more sophisticated and diversified military production capability, with a strong emphasis on advanced technology. The industry is primarily state-owned and heavily regulated by the Chinese government.

Defence Aviation Industry. The military aviation sector is part of China’s broader defence industry and is critical for the People’s Liberation Army Air Force (PLAAF). China’s military aviation industry has rapidly evolved over the past few decades, reflecting its growing emphasis on modernising its armed forces and enhancing its defence capabilities. The industry focuses on producing a range of military aircraft, including fighter jets, transport planes, helicopters, and unmanned aerial vehicles (UAVs). The Chinese military has undertaken extensive modernisation efforts, including developing advanced fighter jets (Chengdu J-20 and J-31, fifth-generation stealth fighters). However, China faces several challenges in developing advanced fighter aircraft engines, which are critical for enhancing the capabilities of its military aviation.

Aero Engine Corporation of China. The Aero Engine Corporation of China (AECC) is a Chinese state-owned enterprise focused on developing, manufacturing, and servicing aircraft engines. It was officially established in August 2016 in response to China’s growing need to develop its indigenous aero-engine technology for military and civilian aircraft. The company merged parts of AVIC (Aviation Industry Corporation of China) and other related entities to consolidate China’s aerospace engine research, development, and production capabilities. Developing advanced Indigenous engines is a strategic priority for China, both for the defence sector and the expanding commercial aviation industry (e.g., China’s domestically developed C919 airliner). AECC aims to reduce China’s reliance on foreign engine manufacturers and to enhance China’s aerospace capabilities, especially in the context of its military modernisation and commercial aviation expansion.

Current State of Development. Historically, China has relied on foreign-sourced engines, and AECC is central to the effort to change that. AECC is focused on developing turbofan and turboprop engines for military jets, such as the WS-10 series (for fighter aircraft) and the WS-15 (for China’s next-generation stealth fighter). It is also developing high-bypass turbofan engines for commercial aircraft, aiming to rival global engine makers General Electric and Rolls-Royce.

- WS-10 “Taihang” Engine. The 13-14 ton thrust WS-10, a product of several years of dedicated development, represents China’s first successful attempt at producing a modern turbofan engine for its advanced fighters. This achievement, intended for use in the J-10 and J-11 fighter jets, is a testament to China’s progress in engine development. While early versions faced reliability issues, newer variants, such as the WS-10B and WS-10C, have reportedly improved significantly in thrust and performance, instilling optimism about China’s future in aviation technology.

- WS-13 “Tianshan” Engine. A turbofan engine (8.5-9 ton thrust), primarily designed for the FC-1/JF-17 fighter, a joint Chinese-Pakistani light fighter aircraft. The WS-13 is a lighter engine designed for smaller fighters and is an alternative to the Russian-made RD-93 engine used in earlier JF-17 models.

- The WS-15 “Emei” Engine. A next-generation turbofan engine with an estimated 18 tons of thrust is a significant milestone in China’s fighter engine development. Designed to power the J-20 stealth fighter jet, the WS-15 is strategically important as it aims to provide the thrust and performance required for fifth-generation fighter jets, particularly for China’s J-20 stealth fighter. Its potential to achieve super cruise capability (sustained supersonic flight without afterburners) underscores the strategic implications of China’s advancements in fighter engine development. Despite facing delays and challenges in achieving the desired performance standards, the WS-15 represents a promising future for China’s military aviation capabilities (Timelines for the development of this engine are attached).

- WS-18. It is a high-thrust turbofan engine for heavy transport aircraft like the Y-20 and may be used in future bomber or tanker aircraft. The WS-18 is intended to replace foreign engines in China’s large transport aircraft, such as the Y-20, which initially relied on Russian D-30KP engines.

- WS-20 Engine. A high bypass turbofan engine designed for the Y-20 transport aircraft, the WS-20 represents another step in China’s efforts to enhance its engine technology and reduce reliance on imports.

China’s Challenges in Fighter Aircraft Engine Development. The complex process of developing reliable, high-performance aero engines presents a significant challenge for AECC. Multifaceted challenges encompassing technological, material, and geopolitical factors hinder China’s quest to catch up with global leaders in engine technology. While the country has made notable strides in recent years, overcoming these challenges is crucial for enhancing its military aviation capabilities and achieving greater self-sufficiency in defence technology.

- Technological Challenges. Developing advanced jet engines involves advanced knowledge and complex engineering challenges, including materials science, aerodynamics, and thermodynamics. Achieving high thrust-to-weight ratios, fuel efficiency, and durability while maintaining stealth capabilities requires innovative design solutions, advanced materials, and cutting-edge technology that has taken years to develop.

- Material Limitations. Engine components must withstand extreme temperatures and stresses. Developing high-performance materials that can endure these conditions is crucial. China needs to catch up in producing advanced alloys and composite materials required for next-generation engines. Advanced manufacturing methods, such as precision casting and 3D printing, are essential for creating complex engine parts. While China has progressed in this area, ensuring quality control remains challenging.

- Reliability and Quality. Rigorous testing and quality assurance are vital to ensuring engine reliability. Despite advancements, Chinese engines have struggled with quality and reliability issues compared to their Western counterparts. Early versions of domestically produced engines, like the WS-10, experienced reliability issues that needed to be addressed through ongoing refinements and improvements. There have been concerns about durability and performance under extreme conditions.

- Research and Development Challenges. Building a skilled workforce with expertise in aerospace engineering and related fields is critical. While China has many engineering graduates, there is a need for more specialised training and experience in aerospace propulsion systems. Although the Chinese government has significantly increased investments in aerospace R&D, various sectors still compete for resources. Prioritising engine development over other military technologies can be a challenge.

- Dependency on Foreign Technology. Historically, China has relied on foreign technology and imports for advanced aircraft engines and critical engine components, especially from Russia. This dependency has limited China’s ability to develop fully indigenous capabilities in this crucial area. For instance, China’s early fighter jets, such as the J-11, used Russian engines (AL-31F), which affected operational independence. While efforts are underway to develop indigenous capabilities, breaking this dependency takes time. Attempts to acquire foreign technology through partnerships and joint ventures have often faced political hurdles, leading to limited access to advanced engine technologies.

- Geopolitical Pressures. Geopolitical tensions, particularly with Western nations, lead to sanctions that limit China’s access to advanced aerospace technologies. This slows down development and innovation in the aviation sector. Competing with established aerospace powerhouses like the United States and Russia, which have decades of experience and technological advancements in engine development, poses another significant challenge.

- Intellectual Property Concerns. Efforts to reverse-engineer foreign engines have raised intellectual property issues, leading to tensions with countries that view these actions as unfair competition.

Present Status. China has been making significant strides in developing indigenous fighter aircraft engines. The country aims to reduce its reliance on foreign-made engines, mainly from Russia, and to enhance its domestic military aviation capabilities. China’s fighter aircraft engine development has advanced significantly in recent years, reflecting the country’s growing ambitions in military aviation. Chinese engineers have made strides in materials science, advanced manufacturing techniques, and thrust vectoring technology, enhancing engine performance and reliability. China has sought to acquire foreign technology to bolster its capabilities. Collaborations with countries like Russia have facilitated knowledge transfer, especially in engine design and testing.

Future Prospects. China is likely to increase its investment in R&D to improve its engine technology further. The goal is to achieve greater self-sufficiency and enhance the performance of its fighter aircraft. The exploration of next-generation technologies, including AI-driven engine management systems, adaptive cycle engines, and environmentally sustainable fuels, could shape the future of Chinese military aviation. Developing advanced fighter aircraft engines is crucial for China’s military modernisation efforts. As tensions rise in the Asia-Pacific region, the ability to produce competitive engines will play a vital role in enhancing China’s defence capabilities.

Strategic Implications. China’s struggles with fighter aircraft engine development have strategic implications, particularly in its military modernisation efforts and aspirations to become a global aerospace leader. Achieving self-sufficiency in engine technology is crucial for ensuring operational independence and enhancing the capabilities of its air force. Continued efforts in this area will be essential for China to strengthen its military aviation capabilities and achieve its broader defence objectives.

Conclusion. China’s fighter aircraft engine development is critical to its broader military modernisation strategy. While significant progress has been made, ongoing challenges remain. The emphasis on indigenous production, technological innovation, and strategic partnerships will be essential for China to enhance its position in the global military aviation landscape. As the situation evolves, monitoring these developments will be crucial for understanding the implications for regional and global security dynamics.

519: INDIAN AIR FORCE: GUARDIANS OF THE SKIES

My Article published in the Millennium Post e-paper

On 08 October each year, India celebrates Air Force Day to commemorate the Indian Air Force (IAF) and its remarkable contributions to the nation’s defence and security. The IAF, with its motto “Touch the Sky with Glory,” has safeguarded India’s airspace and played a pivotal role in defending the nation and in global humanitarian missions, disaster relief, and peacekeeping operations. Established on October 8, 1932, the Indian Air Force has evolved into one of the most powerful air forces in the world, equipped with cutting-edge technology and a highly skilled workforce.

The Indian Air Force was formed as an auxiliary air force of the Royal Air Force under British rule. Its first aircraft were Westland Wapiti biplanes. Its initial role was limited to providing air support to ground forces. In 1950, with India becoming a republic, the “Royal” prefix was dropped. The IAF has been instrumental in every major conflict involving India, including the wars of 1947, 1962, 1965 and 1971 and the Kargil War of 1999, instilling a sense of security and confidence in its capabilities. It has emerged as a formidable South Asian force and a respected power in global military circles.

The IAF has undergone significant modernisation in the last few decades, evolving from a regional force to a major air power with strategic capabilities. This transformation, marked by the induction of advanced fighter jets, helicopters, transport aircraft, and drones, has enhanced its combat and logistical capabilities. The IAF’s current fleet includes state-of-the-art aircraft like the Rafale, Sukhoi Su-30MKI, Dassault Mirage 2000, and the indigenous HAL Tejas. These aircraft provide the IAF with superior air dominance and strike capabilities, ensuring India is well-equipped to face modern-day threats.

The IAF has also invested heavily in enhancing its aerial reconnaissance and surveillance capabilities, with platforms like the AWACS (Airborne Warning and Control System) and UAVs (Unmanned Aerial Vehicles) for real-time intelligence gathering. This modernisation is supplemented by cutting-edge indigenous missile systems like the BrahMos and Akash etc, which offer offensive and defensive capabilities. In addition, the IAF has expanded its reach with its strategic airlift capabilities, allowing for rapid deployment of troops and equipment in any part of the country and even internationally. The C-130J Super Hercules, Boeing C-17 Globemaster III, and the IL-76 aircraft form the backbone of its transport fleet, enabling swift response to humanitarian crises or military threats.

The Indian Air Force prides itself on the rigorous training regimen its officers and personnel undergo. From flying advanced aircraft to mastering complex systems, the IAF ensures that its air warriors are among the best in the world. The IAF also emphasises fostering technical expertise among its ranks. The Technical Branch is responsible for the maintenance and operational efficiency of its vast array of aircraft and equipment. These airmen and engineers ensure that every mission is carried out flawlessly.

In recent years, the IAF has made significant strides in promoting gender diversity. It was one of the first military branches in India to induct women as fighter pilots. Women have served as helicopter pilots, transport aircraft pilots, and now fighter pilots, playing critical roles in operations and missions, further strengthening the force.

The IAF’s role in safeguarding Indian airspace is vital, but its duties extend beyond traditional military operations. The IAF has been crucial in humanitarian assistance and disaster relief (HADR) missions within and outside India. Whether rescuing civilians during natural disasters like floods and earthquakes or delivering critical aid to war-torn regions, the IAF has repeatedly proven itself as a force for good. Its notable large-scale HADR missions in recent years include Operation Rahat in 2013 during the Uttarakhand floods and the 2015 Nepal earthquake.

Moreover, the IAF has been involved in international peacekeeping and support missions under the aegis of the United Nations, showcasing India’s commitment to global peace and security. Its ability to operate in diverse environments, from the icy heights of the Himalayas to the dense forests of the Northeast, makes it an indispensable asset for India’s defence.

Looking forward, the Indian Air Force is poised to face new challenges in the evolving geopolitical landscape of the 21st century. The rise of new technologies like unmanned combat aerial vehicles (UCAVs), cyber warfare, and space-based assets will require the IAF to adapt and innovate continuously. Integrating these technologies into its operations is already underway, with the IAF placing a strong emphasis on building Indigenous capabilities, in line with India’s “Make in India” initiative. As India’s security environment becomes more volatile, with emerging threats from state and non-state actors, the IAF’s ability to remain agile, adaptable, and technologically superior will be crucial.

As we celebrate the Indian Air Force’s contributions on this Air Force Day, it is crucial to recognise its pivotal role in protecting the nation’s sovereignty and contributing to global peace and security. The IAF’s journey from a small auxiliary force to one of the most advanced air forces in the world is a testament to its resilience, professionalism, and unwavering commitment to excellence. With its eyes set firmly on the future, the Indian Air Force is truly a guardian of the skies, ready to face any challenge that comes its way.

515: KURSK INCURSION: TURNING THE TABLES

My OPED published on the EurAsian Times website on 30 Sep 24.

In an unexpected move, On Aug. 6, Ukraine surprised the world by launching a bold pre-emptive offensive attack into Russian territory. Reportedly, over 1000 Ukrainian troops, along with armour, crossed into Kursk Oblast, a Russian region that borders Ukraine to the southeast. Ukraine’s cross-border attack named “Operation Krepost” on Russia’s Kursk region is the most significant incursion by Ukrainian forces into Russian territory since the start of the war. In this operation, Ukraine claims to have seized over 1,000 square kilometres of territory and captured several settlements and hundreds of Russian soldiers. The Kursk attack is distinct in the scale of resources used by Ukraine and its highly secretive nature. The event represents a turning point in the war and global geopolitics, shifting the initiative temporarily from Moscow to Kyiv. It has sparked widespread debate, highlighting the conflict’s potential for escalation and geographical expansion and raising questions about the underlying objectives behind this move and its possible future repercussions.

Surprise, Shock and Awe. Any move into Russia required a surprise. The Ukrainian attack on Kursk was a stunning display of surprise in modern warfare. By employing a mix of operational secrecy, deception, and tactical manoeuvring, Ukraine managed to achieve a surprising advantage. Ukraine had been engaging Russian forces in the eastern regions around Toretsk and Pokrovsk, giving an impression that its primary focus remained there and diverting attention away from the northern border with Kursk. Ukraine also exploited the gaps in stretched-out Russian deployment by attacking an area with lesser defences. In contrast to previous minor ones with irregular forces, the sheer magnitude of the incursion misled Russian military planners, leaving them in shock and awe at the audacity of the Ukrainian troops. The plans were kept tightly under wraps, sharing them only with a tight group of generals and security officials. The attack was executed with remarkable speed and efficiency, limiting Russia’s ability to mobilise reserves and respond effectively in the early stages. This swift strike allowed Ukrainian forces to capture territory and establish control over critical areas before a complete Russian response could be coordinated.

Intentions and Objectives. Ukraine aimed to shift the momentum of the war by launching an offensive into Russian territory. Strategically, Ukraine aimed to divert Russian forces from other critical fronts, such as the eastern regions of Toretsk and Pokrovsk, where Russia had been advancing. While the complete success of this diversion is debated, Ukraine’s offensive has forced Russia to reassess its deployments and react to the threat. Ukraine’s objectives could also be to weaken Russia’s military capability, capture territory, and disrupt Russian supply lines. Some analysts also speculate that holding Russian territory might give Ukraine better leverage in peace negotiations in future. Besides, Ukraine needed to boost its morale after months of defensive operations. A successful offensive into Russia would showcase Ukrainian capabilities and counter Russian propaganda about an inevitable victory. These factors combined to encourage Ukraine to take the risk of crossing into Russia and launching the most significant cross-border attack of the war.

Effect on Russia. The Ukrainian attack on Kursk has had a significant effect on Russia, both militarily and politically. It has forced Russia to divert resources, exposed its military vulnerabilities, and increased internal political and psychological pressure. The Kursk Offensive has further stretched the already heavily engaged Russian military on multiple fronts, further complicating ongoing Russian offensive operations. Ukraine’s capture of territory in Kursk, including several settlements, is a blow to Russian morale and undermines the Russian invincibility. However, it has also significantly boosted Ukrainian morale, providing a much-needed psychological advantage. This also posed logistical challenges, as Ukrainian forces targeted vital supply lines and infrastructure. The Kursk attack is a psychological blow to the Russians, raising fears of further incursions and challenging the Kremlin’s portrayal of the war as distant from Russian territory. The shock of the incursion could also erode public support for the ongoing conflict as casualties rise and domestic security is threatened. The attack puts internal pressure on the Russian government.

Russian Response. Russian President Vladimir Putin called the incursion “a large-scale provocation” and responded by declaring an emergency, imposing heightened security measures in these areas and launching retaliatory counterattacks. Russia mobilised additional troops, mainly from regions close to Kursk, such as Belgorod and Bryansk, to stabilise the situation and prevent further Ukrainian advances. Russia escalated its aerial bombardments across Ukraine, focusing on critical infrastructure, military installations, and supply lines. These colossal airstrikes aimed to disrupt Ukraine’s operations and cripple its logistics. Several missiles (including Kinzhal, Kh-101 and Iskander missiles) and drones attacked 15 of Ukraine’s 24 regions. Russia also deployed more drones and missile systems to target Ukrainian cities far from the front lines. Russia organised ground counteroffensives to reclaim the territory lost to Ukrainian forces in the Kursk region. These counterattacks aimed to regain control of settlements captured by Ukraine and reinforce border defences. Alongside traditional military responses, Russia reportedly increased cyber-attacks on Ukrainian infrastructure and government systems, aiming to weaken Ukraine’s command and control capabilities. Diplomatically, Russia described the Ukrainian attack as a significant provocation, with President Putin labelling it as part of Ukraine’s broader strategy to destabilise Russia. The Russian government used the Kursk attack to rally domestic support for the war effort and called on international partners to limit support for Ukraine.

Ukraine’s Supporters. Several nations and organisations provided critical assistance to Ukraine. The U.S. is Ukraine’s most prominent supporter, providing billions in military aid, including advanced weaponry, intelligence, and training. The U.S. has supplied systems like HIMARS and air defence platforms, which are essential to Ukraine’s defence against Russian advances. Most NATO members, particularly those in Eastern Europe, like Poland, the Baltic States, and Romania, have provided substantial military aid, logistical support, and training. The European Union has also contributed financially, providing billions in aid packages. The U.K. has been a critical supporter, delivering advanced weapons systems and training Ukrainian forces. It has also played a significant diplomatic role, pushing for continued Western support for Ukraine. Canada has offered military and financial assistance to Ukraine, providing artillery systems, armoured vehicles, and drones. It has also imposed significant sanctions on Russia and supported diplomatic initiatives against the invasion. Western defence contractors, particularly from the U.S., have supplied Ukraine with essential technology and equipment. Civil society movements and non-governmental organisations in countries supporting Ukraine have also raised funds and provided humanitarian assistance. These state and non-state supporters have enabled Ukraine to continue resisting the Russian invasion, providing a vital backbone of military, economic, and diplomatic support.

Behind-the-scenes Support. In this instance, a debate has arisen about the direct or indirect involvement of the behind-the-scenes supporters. Washington says it was not informed about Ukraine’s plans ahead of its Aug. 6 incursion into Kursk. The United States has also said it did not take any part in the operation. Russia claims that the United States’ involvement in Ukraine’s incursion into Russia’s western Kursk region was “an obvious fact.” Russia also asserts that Western weaponry, including British tanks and U.S. rocket systems, have been used by Ukraine in Kursk. Media sources have reported that the United States and Britain have provided Ukraine with satellite imagery and other information about the Kursk region in the days after the Ukrainian attack. The intelligence was aimed at helping Ukraine keep better track of Russian reinforcements that might attack them or cut off their eventual withdrawal back to Ukraine.

Crystal Gazing. Ukraine’s advance into Kursk would culminate due to a combination of the Russian response, the number of casualties, and extended lines of communication. The Ukrainian army will probably be unable to hold all of the Russian territory it has advanced on. Kyiv is contemplating a longer-term occupation to use the land as a bargaining chip. This will take a lot of Ukrainian resources, and enforcing a long-term occupation would depend on factors like Ukraine’s priorities, the availability and spare ability of resources, and the severity of the Russian response. The choices include consolidation on the captured terrain and partial or complete withdrawal. Partial withdrawal and consolidation seem to be the logical possibility.

The initial successes achieved by Kyiv in The Kursk attack have further intensified the war and raised questions about the future of the conflict. The Ukrainian offensive into Russian territory has had a profound impact on the course of the war. On one hand, it has boosted the morale of the Ukrainian army and sent a strong message to the West about Ukraine’s ability to take the offensive initiative. On the other hand, the offensive has elicited mixed reactions in Russia. The event has far-reaching repercussions on the entire war, further complicating the situation in the coming period. The war in Ukraine is a complex game, with many intertwined factors influencing the course of events. Both sides are undertaking concurrent campaigns that consume enormous resources (manpower, munitions, and supporting systems). Surge operations for short durations are possible, but sustaining them for long durations is doubtful. The future of this war mainly depends on the extent of continued Western military and political support to Ukraine.
