India’s geographic advantage over China in a potential air conflict along the disputed Himalayan border could prove significant, as the high altitude of the Tibetan Plateau places operational constraints on Chinese military aircraft. However, China’s rapidly expanding air force and growing inventory of advanced combat aircraft are increasingly challenging India’s traditional advantage.
Indian Air Force (IAF) Chief Air Chief Marshal A.P. Singh has highlighted the geographical limitations confronting the People’s Liberation Army Air Force (PLAAF), arguing that although China possesses a larger overall inventory of military aircraft, its ability to employ that strength against India is constrained by the difficult operating conditions of the Tibetan Plateau.
“The PLAAF has a larger overall inventory, but its operations against India are constrained by the geography of the Tibetan Plateau,” Singh said.
He explained that high-altitude airfields reduce aircraft payload, operational range and turnaround times, giving the IAF certain advantages in a potential confrontation.
“The IAF, by contrast, operates from lower-altitude, all-weather forward air bases with full payload and shorter response times,” he said.
Turnaround time refers to the period required for a fighter aircraft to refuel, rearm and prepare for another mission. Response time, meanwhile, describes how quickly aircraft can be scrambled and deployed following an immediate air-defence alert.
Singh’s assessment highlights an important military consideration in the India-China rivalry: numerical superiority does not automatically translate into operational superiority, particularly in the challenging geography of the Himalayas.
However, the reality is more complicated than a straightforward comparison between Indian and Chinese air bases. Several of India’s forward military airfields in Ladakh are themselves located at extreme elevations, comparable to or even higher than some of China’s principal air bases in Tibet.
During the 1962 India-China War, the geographical characteristics of Tibet largely favoured Beijing in its ground campaign.
The Tibetan Plateau’s relatively flat and arid terrain facilitated road construction, logistical movement and the deployment of Chinese troops towards the Himalayan frontier. On the Indian side, steep mountains, deep valleys and dense forests made infrastructure development and military mobilisation considerably more difficult.
The same geography, however, creates a different set of challenges for modern air warfare.
At high elevations, thinner air reduces aircraft engine performance and wing-generated lift. Aircraft require longer distances to take off, while their ability to carry fuel, weapons and other equipment can be restricted.
These limitations are particularly important for fighter aircraft operating from Tibetan airfields, many of which are situated above 3,500 metres.
A fighter operating from a high-altitude base may have to sacrifice part of its weapons payload or fuel capacity to meet take-off and operational requirements. This can affect its combat radius, mission duration and ability to respond repeatedly to threats.
By contrast, aircraft operating from lower-altitude airfields can generally take off with heavier payloads and greater fuel reserves, potentially providing greater operational flexibility.
This is the central geographical advantage highlighted by the IAF chief.
Nevertheless, geography alone cannot determine the outcome of a future conflict. Aircraft performance, airborne refuelling, missile capabilities, surveillance systems, electronic warfare, logistics and the availability of forward infrastructure will also influence the balance of power.
Although Singh emphasised the advantages of India’s lower-altitude air bases, the IAF also operates several important forward facilities in eastern Ladakh at elevations exceeding 4,000 metres.
India operates the world’s highest airstrip at Daulat Beg Oldi (DBO), situated at approximately 5,064 metres above sea level.
However, DBO is an advanced landing ground (ALG), rather than a conventional military air base. Its unpaved gravel-and-earth runway imposes operational limitations and is suitable for selected aircraft, including C-130J Super Hercules transport aircraft and helicopters.
Similarly, the Chushul Advanced Landing Ground is located at approximately 4,267 metres.
One of India’s most strategically important recent developments is the upgraded Nyoma airfield in eastern Ladakh, which was commissioned in November 2025. Situated at approximately 4,175 metres, it is only around 23–35 kilometres from the Line of Actual Control (LAC), the de facto border separating Indian- and Chinese-controlled territories.
The facility is intended to strengthen India’s ability to deploy aircraft, transport supplies and support military operations in the sensitive eastern Ladakh sector.
Another important facility is the Fukche Advanced Landing Ground in the Demchok sector. Located approximately 2.5 kilometres from the LAC, it sits at an elevation of around 4,176 metres.
The Leh airfield, meanwhile, serves as the IAF’s principal logistics hub in Ladakh and is situated at approximately 3,256 metres.
These facilities demonstrate that India cannot entirely escape the operational challenges associated with high-altitude aviation.
Indeed, their elevations are comparable to several important Chinese air bases across Tibet.
China’s Ngari Gunsa air base is located at approximately 4,274 metres, while Shigatse Tingri stands at around 4,317 metres. Qamdo Bamda is situated at approximately 4,334 metres, and Shigatse Peace at around 3,782 metres.
The comparison illustrates that both countries must operate under demanding atmospheric conditions in their forward Himalayan military infrastructure.
India’s more significant geographical advantage comes from its network of air bases in the plains, which allow fighter aircraft to operate from substantially lower elevations before being deployed towards the Himalayan frontier.
Important IAF installations include Ambala, Bathinda, Sirsa, Hasimara and Chabua.
These bases provide relatively favourable operating conditions, allowing aircraft to carry heavier weapons and fuel loads compared with operations from high-altitude airfields.
Hasimara Air Base in West Bengal, home to an IAF Rafale squadron, is located approximately 150 kilometres from the LAC and stands at an elevation of only 104 metres.
In comparison, China’s Shigatse Peace Air Base, located nearly 100 kilometres from the LAC, is situated at approximately 3,782 metres.
Similarly, Chabua Air Base in Assam is around 100 kilometres from the LAC and sits at an elevation of approximately 112 metres. China’s Qamdo Bamda air base is also situated at a comparable distance from the frontier but stands more than 4,000 metres above sea level.
Ambala Air Base in Haryana, which hosts the IAF’s second Rafale squadron, is approximately 500 kilometres from the LAC and sits at an elevation of around 275 metres.
China’s Lhasa Gonggar air base, by comparison, is roughly 200 kilometres from the LAC and is situated at approximately 4,275 metres.
The IAF’s Bathinda and Sirsa air bases are also located around 500 kilometres from the frontier, at elevations of approximately 100 metres.
The difference in elevation can have important implications for aircraft operations. Indian fighters taking off from these plains-based installations can generally operate with fewer altitude-related payload restrictions.
They can also benefit from established infrastructure, relatively favourable weather conditions and shorter maintenance and logistical cycles.
Chinese aircraft operating from Tibet, meanwhile, must contend with thinner air and the associated performance limitations.
However, it would be misleading to assume that Chinese aircraft are unable to operate effectively from high-altitude bases. The PLAAF has invested heavily in infrastructure, aircraft technology and operational procedures designed to mitigate these challenges.
China’s growing use of advanced fighters, improved engines, aerial refuelling and long-range weapons also complicates any assessment based solely on airfield elevation.
## China’s numerical superiority presents a growing challenge
Despite India’s geographical advantages, the widening gap between the two countries’ air forces is a major concern for New Delhi.
The IAF is currently operating with approximately 29 fighter squadrons, considerably below its authorised strength of 42.5 squadrons. This represents a significant reduction in India’s available combat aircraft compared with its long-standing force requirements.
China, meanwhile, possesses a substantially larger military aviation inventory.
The PLAAF has more than 1,800 combat aircraft, including a growing fleet of fifth-generation J-20 stealth fighters. Estimates of China’s J-20 inventory vary, but some assessments place the number in the range of 300–500 aircraft.
The expansion of China’s military aviation capabilities has been accompanied by improvements in air defence networks, satellite surveillance, electronic warfare and precision-guided weapons.
These capabilities could help Beijing offset some of the operational disadvantages associated with the Tibetan Plateau.
China can also draw on military infrastructure beyond its immediate forward air bases, creating additional options for deploying aircraft and supporting operations.
For India, therefore, the challenge is not simply to exploit favourable geography but to maintain sufficient aircraft numbers, modernise its combat fleet and strengthen its ability to sustain operations during a prolonged confrontation.
The debate over the geographical limitations of Chinese air power is not new. It has remained part of Indian strategic discussions since the 1962 Sino-Indian War.
One of the most enduring criticisms of then Prime Minister Jawaharlal Nehru’s wartime leadership concerns his decision not to employ the IAF in offensive operations against Chinese forces.
During the conflict, Indian military aviation was largely restricted to transport and helicopter operations, supporting forward military positions in the then North East Frontier Agency (NEFA) and Ladakh.
The possibility of deploying fighter-bombers for close air support and attacking Chinese military positions was considered but ultimately rejected.
Indian policymakers feared that offensive air operations could provoke Chinese retaliation against major Indian cities, particularly Calcutta, now Kolkata.
At the time, the Intelligence Bureau warned that Chinese aircraft could potentially strike Indian urban centres if New Delhi escalated the conflict by employing its air force.
However, critics argue that this assessment did not adequately account for the operational difficulties facing Chinese aircraft operating from high-altitude Tibetan airfields.
In 1962, the IAF possessed approximately 22 combat squadrons and more than 500 aircraft. Its principal combat aircraft included the Hunter Mk-56 fighter-bomber, the Gnat interceptor, French-built Mystere and Toofani ground-attack aircraft, Canberra bomber-reconnaissance jets and Vampire ground-attack aircraft.
The PLAAF operated aircraft such as the MiG-15, MiG-17 and MiG-19 fighters, alongside medium-range IL-28 bombers.
Several military analysts have argued that India possessed qualitative and quantitative advantages in combat aviation during the conflict, particularly in aircraft operating from the plains.
They contend that Chinese aircraft would have faced substantial difficulties carrying heavy weapons loads from Tibetan airfields, while Indian aircraft could have operated from lower-altitude bases in Assam and Punjab.
General B.M. Kaul, commander of IV Corps in NEFA during the war, criticised the government’s decision not to employ the IAF in close support of ground forces in his 1967 memoir, *The Untold Story*.
British journalist Neville Maxwell, who covered the conflict for *The Times* of London, offered a more cautious assessment in his book *India’s China War*.
He wrote that the Indian government had ruled out tactical air support involving bombers and ground-attack aircraft because of fears of Chinese retaliation against Indian cities, especially Calcutta. Maxwell also questioned whether IAF intervention would have significantly altered the outcome, given the difficult terrain in NEFA and the operational limitations of Indian aircraft.
Nevertheless, the decision remains controversial among military historians and strategic analysts.
Many believe New Delhi overestimated China’s ability to retaliate through air power while underestimating the geographical constraints imposed on the PLAAF by the Tibetan Plateau.
More than six decades after the 1962 war, the strategic environment along the India-China border has changed dramatically.
Both countries are expanding military infrastructure, upgrading forward airfields and deploying increasingly sophisticated combat aircraft near the LAC.
The IAF continues to benefit from lower-altitude bases that offer favourable conditions for aircraft operations. China’s high-altitude Tibetan airfields, meanwhile, impose genuine physical constraints on aircraft performance.
However, China’s numerical superiority, technological investments and expanding fleet of advanced combat aircraft have narrowed the strategic significance of India’s geographical advantage.
Air Chief Marshal Singh’s assessment therefore highlights an important but incomplete aspect of the military balance.
The Tibetan Plateau may constrain Chinese air operations, but it does not eliminate the PLAAF’s ability to project air power.
For India, the central challenge will be translating favourable geography into sustainable military capability through adequate fighter strength, modern aircraft, forward infrastructure and effective joint operations.
In any future confrontation, the decisive factor may not be which country possesses the greater number of aircraft, but which can generate, sustain and coordinate effective combat power under the extraordinary geographical and operational conditions of the Himalayas.
