Taiwan Eyes Phalanx Point Defense Gun Systems To Defend Mountainside Air Bases
As China's military capability has improved, Taiwanese Air Force bases near the country's eastern shore have become increasingly vulnerable.
Amid the rising threat of potential Chinese attacks along its Pacific-facing coastline, Taiwan is reportedly looking to buy land-based rapid-firing guns to help defend the partially underground Jiashan and Taitung Air Bases on that side of the island. A land-based version of the American-made Phalanx appears to be the most likely candidate and these systems would act as point defenses against land-attack cruise missiles, anti-radiation missiles, and small drones.
Taiwanâs Chinese-language outlet Up Media was first to report on the potential contract on Aug. 7, 2018. The story included a screenshot showing a formal request for quotes that was dated June 6 of âMinguo 107,â or 2018. The Taiwanese government uses the Minguo calendar, which started in 1912 with the founding of the Republic of China, for official documents.Taiwan Wants To Speed Up Construction Of Its New Missile-Toting Stealthy Catamarans Posted in The War ZoneThe United States Could Offer Taiwan Leased F-15C Eagles According To Report Posted in The War ZoneU.S. Test Pilots Head To Taiwan To Begin Testing Their Badly Needed Upgraded F-16s Posted in The War ZoneHere's What Taiwan Would Get In $1.3B Arms Deal With U.S. Posted in The War ZoneSAMs And Anti-Ship Missiles Are Now Guarding China's Man-Made South China Sea Islands Posted in The War Zone
The request called for a fast-firin g, but highly accurate gun-based weapon system that can automatically track and engage hostile targets. The system could be either fixed in place or mounted on some form of mobile platform.
The land-based version Raytheonâs Mk 15 Phalanx Close-In Weapon System (CIWS), also known as Centurion, would seem to be the most obvious choice. This turreted weapon system is relatively self-contained, combining a 20mm 6-barrel Vulcan cannon with a rate of fire of 4,500 rounds per minute with an integrated fire control radar suite.
The system can engage targets autonomously or in a manual mode where an operator issues commands. More recent versions add infrared and electro-optical sensors to th e system, increasing its ability to identify, track, and engage targets.
These features have long made it a low-cost close-in defense option for a wide array of ships and also helped Raytheon to port the system over to a ground-based role. The U.S. military began deploying the Centurion version around 2004, primarily in Iraq and Afghanistan, to shoot down incoming rockets and mortar rounds.
But thereâs no reason why it shouldnât still be able to perform many of the same functions it does at sea, where its main job is to blast incoming anti-ship cruise missiles. Raytheon says the latest Block 1B variant can also engage helicopters and small boats.
The company has also used the Phalanxâs sensors to cue a solid-state laser close-in defense weapon to destroy unmanned aircraft, suggesting it could also engage those targets if they were to come into range of the gun. Centurion comes in trailer- and truck-mounted versions, too, which could give the Taiwanese military more flexibility to employ them as necessary and then redeploy to reinforce different areas as needed.
Taiwan could be even more inclined to pick a version of Phalanx given that it already has the systems in service on a number of destroyers, frigates, and missile boats. Itâs a system the Taiwanese military is familiar with and that it already has pipelines in place to support logistically.
It wouldnât be the first time the country has installed a land-based Phalanx system, either. The Taiwanese Navy turned one over to the countryâs Air Force after taking it off a decommissioned ship and it now guards the Leshan radar station in New Taipei City, according to Up Media. The outletâs report noted that the Taiwanese Air Force had considered adding a similar rapid-fire gun system to its defenses across the country in the past, but decided against it given the nature of the threat, as well.
For decades, a major concern for Taiwan had been finding ways to insulate itself against the Peopleâs Liberation Armyâs (PLA) ballistic missiles, which Phalanx or any similar system would have no chance at defeating. The Taiwanese Air Force built Jiashan and Taitung Air Bases on the eastern shores of the island with hangars and other facilities tucked away at least partially inside mountains specifically to make them difficult to hit with a barrage of conventionally armed ballistic missiles.
L and-attack cruise missiles steadily became more of a threat, too, but their range made it hard for ground-based launchers across the Taiwan Strait to engage targets all the way on the other side of the island. Sea- and air-launch platforms were neither numerous or capable enough to truly challenge facilities such as Jiashan and Taitung or do so without risking coming within range of Taiwanese air and shore-based anti-ship defenses.
In recent years, that has all begun to change dramatically as the Peopleâs Republic of China has significantly expanded the size and scope of the stand-off arsenal it could employ during any conflict over Taiwan. Just in May 2018, the PLA Air Force (PLAAF) demonstrated its capabilities in this regard when it flew fighters and bombers in a route that effectively encircled Taiwan.
In any potential conflict scenario, bombers could use land-attack cruise missiles to try to temporarily disable runways or destroy other important targets across the island. Multi-role combat jets would employ anti-radiation missiles against air defense and early warning radars to blind and neuter Taiwanese defenses.
The Peopleâs Liberation Army Navy (PLAN) is also substantially growing its surface and sub-surface forces, adding advanced types with land-attack cruise missile capabilities. Those ships would be able to position themselves on the eastern side of the island, as well.
This is to say nothing of the growing threat of Chinese unmanned aircraft and drone swarms. Spying remains a major concern in Taiwan and individuals could use small quad-copter-type drones to snoop on sensitive facilitie s, such as Jiashan and Taitung, or worse. During an actual conflict, they might perform intelligence or surveillance missions, locate targets for stand-off strikes, or employ their own small munitions, electronic warfare jammers, or systems able to launch cyber attacks to confuse and overwhelm the islandâs defenses or just harass Taiwanese forces.
The stark reality is that bases such as Jiashan and Taitung would be just as vulnerable to Chinese strikes in any future potential conflict and there is a clear need then to update their defenses. Phalanx would offer a relatively simple way to increase protection ag ainst cruise missiles and drones at those sites in the near term and could be a valuable part of a layered defense arrangement in the long run. Itâs a model that the Taiwanese military could easily apply to other sites along the countryâs eastern shore or elsewhere, too.
Any Phalanxes Taiwan buys might serve as the basis for new weapon systems in the future, as well. Raytheonâs SeaRAM uses much of the same physical and systems architecture but features a cluster of 11 RIM-116 Rolling Airframe Missiles instead of the Vulcan cannon. The Taiwanese government has been funding development of a similar domestically-designed system as a replacement for Phalanx, called Sea Oryx.
Itâs possible that Raytheon could substitute a solid-state laser for the gun, or otherwise add that capability on in the future, too. Networking the guns with each other and additional sensor nodes could also improve their pre cision and response times.
In addition, Phalanx is a weapon that Taiwanese authorities have been able to purchase from the United States in the past, which is no small consideration given the political complexities surrounding Taiwanâs self-rule distinct from the government of the Peopleâs Republic of China and its relations with foreign governments. Authorities in Beijing do not respect the islandâs ability to conduct its own foreign affairs and object to arms sales to its military on principle.
There are other similar systems available, such as the Mantis system from Germanyâs Rheinmetall, which combined turreted 35mm cannons with a separate fire control radar. But the officials in Berlin and elsewhere might not be inclined to incite Chinaâs ire.
The United States under President Donald Trump, who has been highly critical of China at times and has now launched a trade war against that country over what he describes as unfair business practices, has had no qualms about approving sales of weapon systems and other military equipment to Taiwan.
Whatever system they end up choosing, and however long it might take to finalize the deal, the Taiwanese Air Force needs an additional last line of defense at Jiashan and Taitung, and potentially other locations, now. Taiwan has already passed on a plan to buy land-based Phalanxes once, when ballistic missiles looked to be the bigger concern, but it can't afford to do it again.
