An invasion of Taiwan would begin with a decisive air battle. Explore Chinese capabilities, Taiwanese defenses, and early warning signs.
In Brief
Before considering a landing on Taiwan, China would have to achieve sufficient air superiority to protect its amphibious forces. This battle would mobilize J-20 stealth fighters, ballistic missiles, electronic warfare assets, and suppression of enemy air defenses (SEAD) capabilities. The objective would be to limit the action of Taiwanese fighters, neutralize anti-aircraft systems, and disrupt enemy command.
Chinese exercises reveal growing preparation for this multi-domain warfare. In November 2026, naval aviation activities around the island and in the Western Pacific also illustrate Beijing’s desire to deter an American intervention. Yet, Chinese numerical superiority does not guarantee success. Taiwan possesses multi-layered defenses, dispersal capabilities, and difficult terrain. China’s main challenge would be less about momentarily conquering the sky than controlling it long enough to sustain an amphibious operation.
Air Superiority, an Essential Condition for a Landing
The Taiwan Strait measures approximately 130 kilometers (70 nautical miles) at its narrowest point. This distance seems modest for modern aviation. Yet it represents a considerable obstacle for a fleet transporting soldiers, armored vehicles, and supplies.
An amphibious invasion requires protecting these ships against enemy aircraft, anti-ship missiles, drones, and coastal systems. Without lasting air protection, a landing fleet would be extremely vulnerable.
Two concepts must be distinguished. Air superiority allows operations to be conducted with limited interference from enemy aviation. Air supremacy corresponds to near-total dominance.
Beijing would not necessarily need to control the entire Taiwanese sky. However, it would need to obtain local and temporary air superiority, and then maintain it during the landing and the delivery of reinforcements.
The Pentagon views this requirement as one of the primary difficulties of a Chinese invasion.
Suppressing Air Defenses Would Pose a Major Challenge
Taiwan possesses an integrated air defense system. It combines surveillance radars, combat aircraft, Patriot PAC-3 missiles, and indigenous Tien Kung systems.
SEAD doctrine, standing for Suppression of Enemy Air Defenses, aims to reduce the effectiveness of these defenses. The mission may include jamming, decoys, or engagements against radar systems. It differs from DEAD, Destruction of Enemy Air Defenses, which seeks their physical destruction.
Chinese Aircraft Possess Complementary Capabilities
The Chengdu J-20 is designed to reduce its radar detectability and fight at long range. The J-16s perform multi-role missions, while their J-16D variant specializes in electronic warfare.
KJ-500 airborne early warning aircraft contribute to surveillance and aerial coordination. However, their effectiveness depends on the integrity of communications and their ability to operate despite the adversary threat.
SEAD never guarantees the complete destruction of a defense. A mobile radar can cease emissions, change position, or operate alongside other sensors. A dispersed defense therefore retains a capacity for resilience even after heavy strikes.
Destroying Runways Would Limit Taiwanese Aviation
Military airfields constitute a central element of any air campaign. Damaging a runway can temporarily halt takeoffs, even when the aircraft remain intact.
China possesses conventional ballistic and cruise missiles capable of striking infrastructure from a distance. However, a damaged runway is not a permanently neutralized base.
Specialized teams can repair surfaces, while dispersed aircraft can use other suitable facilities. The availability of fuel, munitions, and maintenance crews remains equally important.
Notably, Taiwan operates modernized F-16 Fighting Falcon jets, Mirage 2000s, and F-CK-1 Ching-kuo fighters.
During the Han Kuang exercises in August 2026, the Taiwanese military worked on fighter dispersal and adapting units to command disruptions. These measures are specifically aimed at preserving combat capability after an initial attack.
Electronic Warfare Could Shift the Balance of Power
Electronic warfare operates across the electromagnetic spectrum. It includes listening to radar emissions, jamming communications, and protecting friendly systems.
A jammed radar can lose accuracy without being destroyed. An aircraft can also receive incomplete information, complicating the identification of a threat.
The historical principle of these missions is illustrated by the EA-6B Prowler electronic warfare aircraft, formerly employed by U.S. forces.
For China, the stakes extend beyond radars. They involve computer networks, satellites, and joint command. An interruption in communications could slow down the defenders’ decisions, but Chinese forces would themselves remain dependent on their networks.
Beijing’s actual capabilities in cyber and electronic coordination remain difficult to verify. The U.S. report on Chinese military power published in December 2025 still highlights joint integration difficulties.
Chinese Exercises Reveal Growing Military Preparation
The Joint Sword exercises of 2024 and Strait Thunder-2025A trained Chinese forces in encircling Taiwan, conducting precision strikes, and controlling air and sea lanes.
Observations from 2026 continue this trend.
On October 31, Taiwan’s Ministry of National Defense notably identified J-10s, J-16s, KJ-500s, and Y-20U tanker aircraft during a coordinated patrol with the Chinese Navy.
On November 3, Taiwan recorded 49 Chinese air sorties in 24 hours, including 31 inside its air defense identification zone.
On November 10, Taiwanese Minister Wellington Koo reported anti-access exercises in the Western Pacific involving the aircraft carrier Liaoning. According to Taipei, more than 100 Chinese military and coast guard vessels were observed across a wide regional area.
These maneuvers are of particular interest to Washington. China’s A2/AD strategy, standing for Anti-Access/Area Denial, aims notably to complicate the intervention of external forces.
Early Warning Signs of an Invasion Remain Difficult to Interpret
Exercises around Taiwan do not mean an invasion is imminent. They also serve to exert political pressure, test adversary reactions, and maintain uncertainty.
A true preparation for war would likely be distinguished by a much broader military and logistical mobilization, a lasting shift in force posture, and exceptional measures affecting civilian activities.
Analysts would need to examine several indicators simultaneously, rather than an isolated spike in air sorties.
Moreover, on November 14, 2026, Taiwan reported only ten Chinese sorties over the observed daily period. Variations remain significant.
Intense military activity does not constitute proof of an impending invasion.
The assessment published in March 2026 by U.S. intelligence indicates that Beijing does not appear to have a set timetable for invading Taiwan, including in 2027.
The American Risk Considerably Complicates Chinese Calculations
The air battle would not be exclusively Sino-Taiwanese if the United States decided to intervene.
The U.S. presence in Japan, naval aviation capabilities in the Pacific, and Western intelligence assets could profoundly alter the military balance. However, intervention is not automatic: Washington maintains a policy of strategic ambiguity regarding its military response.
For Beijing, this uncertainty is fundamental. A campaign initially designed to coerce Taiwan could trigger a much broader regional conflict.
China possesses significant quantitative superiority over Taiwanese aviation. Yet it has never demonstrated its ability to sustain air dominance in a major war against a modern defense backed by the United States.
The decisive question therefore goes beyond the number of available fighters or missiles. Control of the skies must be sustainable. An amphibious operation requires continuously protecting exposed forces while maintaining their supply lines.
It is precisely this requirement for endurance, combined with the risk of American intervention, that makes an invasion of Taiwan one of the most difficult and dangerous military operations Beijing could undertake.
