In response to the Russian war on Ukraine, neighbouring countries have decided to take concrete steps towards strengthening their air security. On October 13, 2022, fourteen NATO member countries, plus Finland, signed a Letter of Intent initiating the development of a “European Sky Shield Initiative” (NATO, n.d.). The European Sky Shield Initiative creates a joint defence system “through the common acquisition of air defence equipment and missiles by European nations” (NATO, n.d.). Furthermore, the project enhances interoperability between the countries and strengthens NATO’s Integrated Air and Missile Defence (NATO IAMD).
