Secretive discussions are taking place among European Admirals regarding North Atlantic defense strategies, prompted by the shrinking presence of the RN and its unprecedented decline. The gathering, convened by the French Navy ahead of the Euronaval defence exhibition, highlights a growing shift among allies who are increasingly measuring Britain by the forces it can actually put to sea rather than its ambitions for the future.
At the center of these discussions is concern over the RN’s rapidly shrinking escort fleet and inability to deploy SSNs. Geography, past experience, and a successful legacy of sea power have traditionally led to the expectation that Britain would supply naval leadership within the High North and North Atlantic. However, other navies cannot base their planning on ships that exist only in future programmes.
The warning signs have accumulated for some time. While giving evidence to the Commons Defence Committee in March, Dr Marc De Vore of the University of St Andrews highlighted a growing gap between British rhetoric and available forces. Recounting a visit to the French Atlantic Fleet headquarters, he pointed to criticism from a French admiral regarding the scarcity of UK attack submarines available for operations in the High North.
Strategic Reality Versus Official Rhetoric
Deterrence is based partly on what an opponent believes can actually be deployed at short notice. Russian planners can count available hulls just as easily as NATO partners, rendering ambitious announcements regarding future frigates, autonomous vessels and force structures less persuasive against declining numbers at sea.
This tension was underscored when Gwyn Jenkins delivered a thoughtful speech on lessons from the wartime Battle of the Atlantic. Emphasizing that Britain’s security remains fundamentally dependent on control of the sea, he noted that the GIUK gap forms the open sea border with Russia. He challenged military readiness with a direct standard: asking whether forces can fight tonight, sustain the fight tomorrow, and adapt faster than adversaries.
Yet his assertion in the same address that Britain is “still one of the most powerful navies in the world” drew skepticism when measured against current outputs. Both of the fleet’s aircraft carriers are currently deployed at sea; however, HMS Queen Elizabeth is operating alone without defensive armaments while its crew undergoes work-up training. Meanwhile, HMS Prince of Wales has a single RN escort and is reliant on a Norwegian frigate for ASW capability beyond a handful of embarked helicopters. Providing a combat air patrol to safeguard the vessel is manageable for the 6 embarked jets, but their limited numbers fall short of creating a significant deterrent threat.
The Atlantic Bastion Concept and Short-Term Hurdles
To address these capability deficits, the official line is that the “Atlantic Bastion” concept is the answer. This framework aims to combine frigates, P-8A Poseidon aircraft, submarines, seabed sensors, uncrewed surface vessels (USVs), and underwater vehicles into a persistent anti-submarine network spanning the North Atlantic. European allies are also considering participation in various forms.
Nevertheless, the initiative remains in its infancy. Trials for the Royal Navy’s initial large uncrewed surface vessel prototype are not anticipated to commence until next year, and designs for the Type 9X LUSV remain far from fully developed. While distributed sensors will eventually alter the economics of anti-submarine warfare, networks still require aircraft, submarines, and suitably equipped surface ships to prosecute contacts and protect convoys or reinforcement routes.
Industry observers note that the only realistic short-term response is emergency action and additional funding to accelerate delivery of both Type 26 and Type 31 frigates. An unconfirmed report by The Times indicates that the RN is examining options to speed up Type 31 construction at Rosyth through additional recruitment and extra or double shifts. Bringing the Type 26 anti-submarine warfare specialists into operational service is vital, provided that accelerated build schedules are matched by a resolute commitment to fast-track acceptance, certification, crew training, and weapons trials.
Thirteen new frigates remain under construction, and the carrier force has demonstrated considerable reach. However, military experts warn that as European nations formulate backup plans to compensate for British naval shortcomings, stepping into the void left by the UK will transfer leadership elsewhere, making it notably more difficult to regain that trust later on.
