Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what analysis his Department has conducted on the strategic implications for NATO of Russia’s enhanced Arctic infrastructure, including air base expansions and deployment of advanced air defence systems such as S-400 on Novaya Zemlya.

The Ministry of Defence keeps Russian military capabilities and investment under continuous review. We work closely with our NATO Allies to understand the implications of Russian military capability development for Alliance security. NATO is strengthening its deterrence and defence as a result of the increasing threat from Russia and will continue to adapt as necessary.

Hypersonic missiles are just one type of many Russian air and missile capabilities. In light of the increasing threat the UK faces, His Majesty's Government announced up to £1 billion of investment for Integrated Air and Missile Defence in the Strategic Defence Review.

This is part of a comprehensive and integrated approach to deterring and defending against the range of strategic threats we face.
