will equip part of its new F-16s with. The final signing of the Letter of Offer and Acceptance (LOA) for the purchase of 66 F-16V fighter jets was confirmed on December 21, 2019. Hardened bases and survivability Taiwan faces the threat of Chinese missile strike on its airfields. PLA accurate ballistic missiles and cruise missiles can damage or destroy airfields and aircraft on the ground. Taiwan has hardened key Air Force facilities and built redundancies into critical infrastructure so that it can absorb and survive a long-range missile precision attack. Taiwan Air Force built at least 400 protected revetments in its 9 bases, approximately half of them covered. Underground hangars were built at Chiashan Air Force Base in Hualien that reportedly can protect over half of Taiwan's tactical fighter aircraft. Other underground shelters exist at Chihhang Air Base and perhaps elsewhere. But missiles can target the runways with warheads designed to crater them and so prevent Taiwan's aircraft from taking off. Taiwan regularly practices dispersing its aircraft from the more vulnerable West coast bases to the East coast. Units are also moved between bases to make it more difficult to know where they might be at any given time. Dummy aircraft are parked on bases and inside shelters to confuse Chinese intelligence. Besides this Taiwan maintains emergency highway strips where planes can land, refuel, rearm and take off in the event that bases are out of service. Each Taiwanese airbase has an engineering unit attached for rapidly repairing runways. Taiwan is working to provide additional layers of defenses around military airfields against cruise missiles, antiradiation missiles and small drones, as well as potentially larger threats, such as helicopters and low-flying aircraft. Ground version of Sea Oryx SAM and Phalanx CIWS are being developed and deployed to improve air defense. One of the primary methods of surviving in case of war will be deception and the use of decoy targets. This applies to decoy planes, SAM launchers, radars, etc. Decoys makes use of Taiwan's geographic advantages, especially its mountainous and urban terrain which complicate enemy targeting and kill chain completion.
