UK's DIP maps four autonomous platforms to power a hybrid Royal Navy and Atlantic Fleet

Britain’s Defence Investment Plan outlines four new platform types—two UUVs (Type 92 and the large Type 93 XL UUV) to bolster underwater sensing and ASW, plus Type 94 and Type 91 uncrewed platforms for sensing and missiles—to underpin a Royal Navy hybrid force and its Atlantic Fleet concept. The plan, tied to SDR goals and a £5 billion push into autonomous systems, envisions expanding Common Combat Vessels in the 2030s, expanding seabed security and air/ missile defense capabilities, and upgrading naval base infrastructure to improve readiness and deterrence in the underwater domain and beyond.
