The Royal Navy currently has fewer than 20 vessels active, including coastal boats. This is not enough to secure fisheries, defend the home islands, interdict drugs before they arrive, and to keep open the global shipping lanes Britain relies on existentially. There is no redundancy. Until earlier this year, only one Type 45 destroyer was operable. It had to be removed from its duties and sent to defend Cyprus from air attack, but it took a week to get it ready to leave.

Since the 2010 Strategic Defence Review, British military capability has been gutted. A large investment is now needed to course correct. Many European powers fell into the same complacency trap at the same time.

Some countries, like Ireland, have never had adequate military capability. Ireland has no surface to air missiles - not even a radar tracking system - and no jet aircraft at all. Again, half of its 8 naval vessels are inactive. Russia has been camping out in or near Irish waters happily doing whatever they please. Considering the amount of European data going through Ireland, this is a concern and the Dail is considering whether they need a more comprehensive military.
