Some observations on this National Defense University (USA) article posted in the strategic news section by
@Taiban and how it relates to PLA strategy.
First, a statement I found interesting.
Given that a likely U.S. response to such a Chinese close blockade of Taiwan would include a U.S. “distant” blockade of China (for example, by disrupting maritime shipping through the South China Sea), such a campaign could unfold as a series of concentric rings, each representing a logistics contest on a different scale.
So basically the US plan is to do what they said China was going to do (restrict shipping in the SCS for political gain) when they started raising concerns about PLA South China Sea outposts. Lol.
Now to the meat of the article. It starts by stating that no matter how advanced (or, on the other hand, unsophisticated) your combat forces and tactics are, if you have poor logistical forces you will fail. The Imperial German Army's 1918 offensive was tactically brilliant but logistically mediocre, resulting in its defeat. The French possessed massive technological superiority over the Viet Minh but lost at Dien Bien Phu on account of both choosing a place of battle that was difficult to logistically support, but also on account of the efficient logistical capability of the Viet Minh. It then examines the operational concepts developed by the USMC, US Army, and USAF, and their logistical weaknesses. It ends with ideas about steps that could be taken to alleviate the situation and resolve logistical issues.
Although the article's focus is on logistics, it raises excellent points on the redundant nature of the USMC and US Army concepts for participating in a war against China. More or less, both sides envision deploying anti-ship and anti-air assets to islands in the 1IC; in the case of the Marines, in the South China Sea and Ryukyu Islands; in the case of the Army, focus seems to be on the Philippines. The article raises an important point: these guys have needs for food and other stuff besides ammunition. So if you're sending ships and aircraft to resupply them anyways, why not use the ships and aircraft to conduct those strike missions? The article, perhaps without the author not noticing, makes a
damning (IMO extremely, hence the emphasis) comparison with the redeployment of IJA troops to Guadalcanal after the US invasion. What was supposed to strengthen Japanese offense and defense ended up becoming such a liability, even requiring the commitment of destroyers to transport supplies and troop reinforcements, that it cost them the battle and created numerous opportunities for the US to destroy Japanese naval forces.
On the USAF proposal, which is to deploy small numbers of aircraft on small airports on various islands, the article raises a variety of questions. First is that existing Air Force logistics are not conducive to supporting this kind of force. For example, software updating, a vital aspect of modern aircraft maintenance, is generally conducted at a single base where an entire squadron (or squadrons) can be present. If the Air Force was to try to put this concept into practice in 2025, it would find itself not having the needed equipment to maintain aircraft at separate bases. Second, history shows that distributed operations need to generate high sortie/strike rates to be successful. During the invasion of Poland in 1939, the Polish Air Force operated from numerous auxiliary bases and fought well, but flew so few sorties, on account of losing supplies each time they evacuated a base and flew to one further in the rear, that they did not pose a major threat to the Luftwaffe. The article also notes that the Air Force concept is probably based on operations during WWII and Korea. Aircraft are extremely sophisticated now compared to then. Soviet aircraft, as well as some European aircraft, were designed in the Cold War with operations from austere locations in mind due to the threat of nuclear strikes, but American aircraft are not. It is important to ask if an F-35 can operate from a crummy civilian airport in the Ryukyus or Philippines.
As for implications about PLA strategy, the article essentially affirms a very basic observation: China is close to its main objective, Taiwan, and the US is not. The US has too far to go to keep its units supplied, not so much at all, but in order to keep up with Chinese offensive and defensive power (Example: it can't supply enough Tomahawks/JASSMs to break through the IADS for strikes on Chinese bases, and nor can it provide enough Patriots and SM-3s to stop Chinese ballistic missile salvoes).
I think this also says something about what performance can be expected from the Taiwanese Air Force: basically nothing (should be expected). Taiwan does practice highway airfield operations, but considering it is well known cuts have been made to the Taiwanese military's logistical forces as a whole, if they manage to evacuate in sizable numbers to these bases it wouldn't be surprising for them to be poorly supplied. Thus the Air Force is choosing to either be ineffective in the air (that is, if the highway airfields themselves aren't targeted in the first place) or be destroyed at their big, easily targeted bases.
If the US was to attempt its distributed operations concepts, it might become attractive for the PLA to seize these island bases. Doing so would come with considerable risks. Such operations would probably occur while Taiwan is still being blockaded/bombarded, leaving amphibious assets available for other operations. The PLA would have to make a choice as to whether it wants to risk these assets to capture these islands or save them for an eventual amhibious assault on Taiwan.
If the CPC's desire is to end the war as quickly as possible (in victory), it would be advantageous to seize these islands. I just cannot imagine China fighting the US and its allies and then letting 071s, 075s and 076s sail around in circles in the Bohai Sea or sit pierside so as to "save" them for Taiwan. If the US does decide not to approach Taiwan, seizing (prior to US deployment there) or assaulting (after US deployment there) the islands are good options to lure the US Navy into battle. It would be a good role for the PLANMC, which (IMO, please correct me if wrong!) is somewhat redundant due to the PLAGF having amphibious combined arms brigades. If it wished to transform these bases into outposts for long-range AD weapons and AShMs, China actually has the logistical capability to resupply these bases in the form of its merchant marine, and the bases could prove useful in keeping the SCS and ECS open after the breaking of an American blockade.
Because more or less
all of these outposts would be in the Philippines and Japan, seizing them would also resolve China's territorial disputes with the former and act as a stepping stone to neutralizing the hostile attitude of the latter (either in the form of liberating the Ryukyus or a "drive hard into enemy territory and then pull back" strategy as used in the Sino-Vietnamese War).
