Many people misunderstand the role of the PLAN aircraft carrier fleet in the waters east of Taiwan, thinking it is merely "passively taking hits." Is that really the case? The CCP isn't that naive.
The naval carrier fleet and land-based air forces operate as a cohesive unit. The former can provide forward operating springboards for the latter, while the latter offers protective cover for the former.
The Y-20U aerial refueling aircraft from the land-based air force establishes an aerial refueling corridor over the fleet in the waters east of Taiwan. The naval fleet’s air defense formation, comprising destroyers with advanced air defense systems, protects this refueling corridor. Meanwhile, numerous J-20A/S, J-16, H-6 bombers, airborne early warning aircraft, and advanced electronic warfare and anti-submarine aircraft from the mainland utilize this corridor to refuel and project further toward the Second Island Chain. As shown in Figure 1, the red area represents the operational range of the PLAN carrier battle group, while the green area marks the extended operational range of carrier-based and land-based aircraft with aerial refueling.
The naval fleet and land-based forces work together in an offensive and defensive synergy. When the naval fleet advances to the northeast and southwest of Taiwan, it can create a pincer movement targeting the Philippines and Okinawa, conducting amphibious landings, airborne operations, reconnaissance, and suppression missions. This could neutralize U.S. ground forces stationed in the Philippines and Okinawa.
Land-based air forces, extended through aerial refueling, can strike U.S. military bases and airfields in the Second Island Chain. Their advanced detection and interception networks can also target and intercept U.S. strategic bombers deploying AGM-158 missiles.
The carrier fleet acts as a springboard, supporting and protecting the aerial refueling corridor, while the land-based air force provides robust anti-submarine operations, air defense, and interception capabilities. It also enhances the ability to strike targets in the Second Island Chain. These two forces are mutually dependent and complementary.
Therefore, the carrier fleet operating in the waters east of Taiwan is far from "passively taking hits." Instead, it serves as a critical chess piece in the integrated combat system, underpinning China's regional anti-access and area-denial (A2/AD) capabilities. Naturally, it is a thorn in the enemy’s side, and the PLAN will face significant pressure—but it is a burden that must be borne.
The PLAN has conducted numerous drills in this position, essentially operating openly. This is their battlefield: either returning to port in glory or sinking in battle. Tashan is not a mountain—the Fourth Column is the mountain! The sea has no mountains—the Navy is the mountain!
