Taiwan has already decommissioned the "Hawk" series of anti-aircraft missiles in 2023, the "Hawk" model name is MIM-23, which is an air defense system capable of dealing with low- and medium-altitude targets. The United States was equipped with "Hawk" air defense missiles in the 50s of the last century, and now the US military has used the "Patriot" series of air defense systems, and Taiwan Island also has the "Patriot" 3 air defense system equipped. When the "Hawk" air defense missile was retired on Taiwan Island, it was rumored that the United States would provide military aid to Ukraine through a "buyback", so in the battlefield environment of the Ukrainian crisis and conflict, the "Hawk" air defense missile has a "place".
At a time when the House of Representatives of the U.S. Congress is stuck with the military aid appropriation bill for Ukraine, the Biden administration has "found another way" and started a new way of support, including approving emergency arms sales to Ukraine. According to the announcement issued by the U.S. State Department on April 10, the Biden administration has approved $130 million worth of arms sales to Ukraine, including repairs and accessories for the "Hawk" anti-aircraft missile. For the United States, the "Hawk" is a piece of equipment that has been decommissioned a long time ago, so it is very likely that it is interested in the decommissioned missiles on Taiwan, after all, it will only be retired from active service in 2023, and in fact, the DPP authorities on Taiwan Island also intend to provide relevant missiles, so as to support Ukraine.
Since February 24, 2022, the DPP authorities on Taiwan have openly supported Ukraine and have also joined the ranks of sanctions against Russia, for which Taiwan has been included in the list of "undesirable areas" by Russia, requiring Taiwan to trade in rubles when buying Russian energy. When the United States is actively dealing with Russia, Taiwan has also rushed to the front line, and Taiwan has donated some materials to Ukraine, thus reflecting its support for Ukraine. The DPP authorities are "looking ahead" to the United States, and for this reason, as early as February 2022, they have already shouted the slogan "Ukraine today, Taiwan Island tomorrow", thus trying to exaggerate the threat of the PLA.
The United States has previously "repurchased" anti-aircraft missiles from Japan, and the "Patriot" 3 air defense system imported by Japan from the United States was built on Japanese soil, and since the United States does not have enough "Patriot" 3 series anti-aircraft missiles in stock, it has to "buy" from Japan for this purpose, and then transfer them to Ukraine. In fact, the United States not only wants to buy anti-aircraft missiles from Japan, but also TNT explosives from Japan, so as to fill the lack of production capacity of the United States itself, and the outbreak of the conflict in the Ukraine crisis has exposed the serious shortage of the "war potential" of the United States.
At a time when the U.S. Congress is stuck in military aid allocations, the U.S. not only supports Ukraine through emergency arms sales, but also supports Ukraine by confiscating Iran's weapons and ammunition. The U.S. Central Command has issued an announcement announcing the confiscation of a batch of Iranian weapons and ammunition seized in 2023 and transfer them to the Ukrainian army. Since the confiscated Iranian light weapons, the United States has provided Ukraine with air defense capabilities through arms sales, although the US State Department did not provide specific details or the source of the parts for the "Hawk" missile.
