The Folks’s Liberation Military’s (PLA) air intrusions into Taiwan’s Air Protection Identification Zone (ADIZ) have raised loads alarm and inspired unsupported claims concerning the rationale and function of those sorties. The most typical declare suggests these flights are directed at Taiwan and represent a part of China’s broader “gray zone” actions in opposition to the self-ruled island. As I’ve opined elsewhere (see here and here), Taiwan is usually solely not directly touched by these incursions, with many of the large-scale intrusions possible directed in opposition to the USA and/or formal U.S. engagement with Taiwan.
The most typical incursion sort has concerned a single KQ-200 maritime patrol and anti-submarine warfare (MP-ASW) plane. The close to every day presence of the KQ-200 denotes an operationally vital rationale, one which has little to do with Taiwan instantly. Since coming into service inside the Japanese Theater Command in 2018 and the Southern Theatre Command a number of years earlier, the plane has stuffed an necessary functionality hole, offering the PLA Naval Air Power (PLANAF) a functionality to persistently monitor overseas submarine and floor ship exercise at or close to important maritime chokepoints and sea lanes of communication alongside the First Island Chain.
The KQ-200 has been concerned in 70 percent of all incursions since September 2020. This makes the sort the most typical intruder into Taiwan’s ADIZ. Furthermore, an in depth evaluation of the KQ-200’s deployment patterns reveals some attention-grabbing particulars concerning the plane’s mission and incursion rationale. Based mostly on sample evaluation of the sort’s ADIZ incursions over the previous two years, the KQ-200 is often recorded loitering over the identical geographic location roughly half-way between the most important port metropolis of Kaoshiung in mainland Taiwan and the Pratas Island, as illustrated in Determine 1. This raises some attention-grabbing questions concerning the sortie rationale.

Utilizing this sortie sample as the idea, we will draw a straight line between the town of Kaoshiung and the Pratas Island as a reference level for additional evaluation (see Determine 2). Utilizing this as a reference, Determine 2 additionally illustrates the identical line in opposition to a satellite tv for pc picture from Google Maps, offering us with a extra helpful geographical reference level for evaluation.

The recognized space of curiosity is especially vital when in comparison with topographical and bathymetric maps proven in Determine 4. The topographical and bathymetric circumstances create two pure submarine interception factors in opposition to U.S. Navy’s nuclear-powered assault submarines (SSNs) within the northern a part of the South China Sea. The primary alternative is within the Bashi Channel and Luzon Strait, which have shallow waters and few pure hideouts. The second interception alternative in coming into the Taiwan Strait is the upward slope of the South China Sea Slope, an necessary underwater topographic future connecting the South China Sea and mainland China. Submarines are compelled to ascend alongside the South China Sea Slope to the shallower waters of the South China Sea Shelf.
In an earlier work, Lu Li-Shih wrote that this “underwater geography, with a complicated mix of seabed sediments along with its hydrological environment and geographical location, makes the area greatly suitable for ‘submarine area hunting’ for Taiwanese forces.” If the submarine geography can certainly be thought of as an excellent “submarine hunting ground” for the Taiwanese navy, it should even be of nice curiosity to the PLAN as nicely. This might nicely go a great distance in explaining the frequent PLAN KQ-200 sorties over this explicit geographic and submarine topographic space.
Furthermore, the USN dispatches its personal anti-submarine and maritime patrol plane, P-8A Poseidon, sorties continuously to the exact same geographic space (see, for instance, here, here and here). The truth that the U.S. P-8s – in addition to different capabilities typically supporting these missions, like KC-135 aerial refueling plane, RC-135 and EP-3 signals-intelligence assortment plane, and even Triton high-endurance and long-range unmanned methods – continuously orbit over both the strategic Bashi Channel (see here, here, and here) or the South China Sea Slope, additional demonstrates the importance of this discovering. Open-source intelligence sources have additionally proven the occasional simultaneous presence of each Chinese language and U.S. ASW plane circling over the identical space on the similar time, suggesting a mutual curiosity in screening one another’s submarine actions.
Along with one other important maritime chokepoint north of Taiwan, the Miyako Strait between the Japanese islands Miyako-shima and Okinawa, one other important chokepoint, the Bashi Channel, to the south, join the western Pacific to the South China Sea. These geographical options additionally function conduits for any U.S. forces touring from the continental United States, Hawaii, or bases alongside the Second Island Chain, similar to Guam, to the South China Sea and the Taiwan Strait. Due to this fact, the 2 straits are of nice strategic significance to China, each within the PLA’s try to “break out” from the First Island Chain to the western Pacific and in denying the U.S. Navy entry to the realm in instances of battle. Moreover, the South China Sea Slope affords the PLA one other viable interception level in opposition to U.S. SSNs coming into the Taiwan Strait.
One other believable clarification for the close to every day intrusions of the KQ-200 within the space and, particularly, flights throughout the Bashi Channel to the western Pacific, relate to the sort’s perform because the PLAN’s major maritime patrol plane. The kind isn’t just an anti-submarine warfare plane but additionally an efficient maritime patrol plane. Determine 5 illustrates the sort’s occasional long-distance missions, taking the plane throughout the Bashi Channel and into the western Pacific. The info supplied by Taiwan’s MND additionally present the plane’s typical flightpath turning northeast alongside the ocean lanes of communication coming from Japan’s path towards the South China Sea. Importantly, that is additionally the path from which USN vessels primarily based in Yokosuka, Japan, would arrive within the space. Moreover, the USN and Japanese Maritime Self-Protection Power typically conduct joint workout routines south of Okinawa, within the Philippine Sea. That is arguably all of nice curiosity to the PLA in gathering intelligence details about USN actions.

Lastly, as I’ve mentioned elsewhere, the closely tasked KQ-200s are additionally a typical ingredient of bigger formations intruding into Taiwan’s southwest ADIZ. The kind is continuously recorded as part of a particular incursion sample that strongly resembles maritime strike coaching (see here, here and here), looking for floor targets and relaying goal info to the anti-shipping succesful fight plane. Furthermore, in case of large-scale incursions, involving not less than 10 plane, not less than one KQ-200 has often been a part of the formation. In some events, two KQ-200s have been current, main separate parts of the bigger formation (see here and here). The KQ-200 is often recorded main these combined formations, which embody anti-shipping-capable H-6K bombers and particular mission plane like digital warfare or intelligence, surveillance, and reconnaissance platforms, in addition to escorting fighters via the Bashi Channel into the western Pacific (see Determine 5). The involvement of the KQ-200 in such formations factors strongly to maritime strike coaching. Moreover, in a number of instances these large-scale incursions have coincided with USN provider strike group presence missions (see here, here, and here) coming into or exiting the South China Sea through the Bashi Channel. Most lately, the biggest incursion recorded up to now, on October 4, involving 52 plane, was very possible a response to the simultaneous motion of two provider strike teams – USS Carl Vinson and HMS Queen Elizbeth – via the Bashi Channel.
The standard narrative frames Taiwan because the goal of Chinese language air incursions. Against this, the median incursion sort, together with probably the most frequent intruder, the KQ-200, demonstrates clearly that these incursions have a rationale past Taiwan. The KQ-200 sorties, for instance, almost definitely characterize the PLA’s precise strategic and operational pursuits in monitoring overseas warship actions, not least U.S. plane provider strike teams coming into or exiting the First Island Chain via the Bashi Channel. Equally, the PLA has an excellent curiosity in looking for and “prosecute” U.S. SSNs coming into the South China Sea or the Taiwan Strait through the Bashi Channel and the South China Sea Slope.
These findings go a great distance in explaining the rationale of the close to every day KQ-200 intrusions into Taiwan’s southwest ADIZ. This additionally serves to underline that, for causes of geography and topography, the PLANAF KQ-200s would enterprise into and orbit across the very geographical areas whatever the existence of Taiwan’s ADIZ.
