UK is a signatory member - what are we signing up to buy?
Its not NATO ACCS, we pulled out if that, it’s not a common NAEW replacement, we’re committed to E-7. It’s not a common fighter, we are committed to Tempest. We don’t have any MSAM or plans - currently - to buy any for the homeland defence, we already have CAMM as part of Sea Ceptor and Sky Sabre.
And how does this fit in with PESCO?

14 NATO Allies and Finland agree to boost European air defence capabilities
Defence Ministers from 14 NATO Allies* and Finland came together in Brussels on Thursday (13 October 2022) to sign a Letter of Intent for the development of a “European Sky Shield Initiative”. Spearheaded by Germany, the initiative aims to create a European air and missile defence system through the common acquisition of air defence equipment and missiles by European nations. This will strengthen NATO’s Integrated Air and Missile Defence.
“This commitment is even more crucial today, as we witness the ruthless and indiscriminate missile attacks by Russia in Ukraine, killing civilians and destroying critical infrastructure. In this context, I strongly welcome Germany’s leadership in launching the European Sky Shield Initiative,” said NATO Deputy Secretary General Mircea Geoană. He added: “The new assets, fully interoperable and seamlessly integrated within the NATO air and missile defence, would significantly enhance our ability to defend the Alliance from all air and missile threats.”
The initiative will allow all participating nations to jointly develop an air defence system using interoperable, off-the-shelf solutions. This multinational and multifaceted approach offers a flexible and scalable way for nations to strengthen their deterrence and defence in an efficient and cost-effective way.
* The 14 NATO allies included: Belgium, Bulgaria, Czechia, Estonia, Germany, Hungary, Latvia, Lithuania, the Netherlands, Norway, Slovakia, Slovenia, Romania, the United Kingdom
