The SSN-AUKUS programme – the trilateral submarine project that will deliver next-generation nuclear-powered attack submarines for the UK and Australia – has had a productive few months. The UK’s commitment to acquiring up to twelve boats would represent the largest Royal Navy submarine fleet in decades, and the most significant commitment to undersea warfare capability in a generation.
The recent Defence Investment Plan outlined an important decision for the Royal Navy: the cancellation of the Type 83 destroyer, and its replacement with something genuinely new – a Hybrid Navy built around a family of autonomous surface and underwater platforms. The case for the Hybrid Navy is coherent, but its execution remains to be seen.

In 2025, Norway announced its intention to procure at least five Type 26 frigates – the country’s largest ever defence investment. In April 2026, it formally entered a four-nation partnership with the United Kingdom, Canada, and Australia to coordinate the development of a common class of surface combatants derived from the Type 26 design.
HMS Active, the second of five Inspiration-class Type 31 frigates, was rolled out of its construction hall at Babcock’s Rosyth facility in February 2026 and floated from its submersible barge the following month. Three of the five Type 31s are simultaneously in various stages of production: for a UK warship programme, that degree of concurrent activity is worth noting.
Directed energy weapons have been “just around the corner” for so long that healthy scepticism has become the default response to any announcement in the field. In March 2026, that changed. The Minister for Defence confirmed the acceleration of DragonFire’s deployment onto Royal Navy Type 45 destroyers by 2027 – a reduction of approximately five years compared to earlier planning timelines.
The UK has unveiled work on its Atlantic Bastion programme, aimed to counter Russian threats to undersea infrastructurein the North Atlantic. It heralds a transformation of the Royal Navy and its submarine-hunting capabilities.
