Background

Type 93 is the Royal Navy's planned extra-large uncrewed underwater vehicle, grown from the existing Excalibur programme for long-endurance underwater surveillance, with its role confirmed in July 2026 alongside sibling classes Type 91, 92 and 94.

Excalibur is the Royal Navy's existing extra-large uncrewed underwater vehicle development effort; Type 93 formalises that work into a named class within the four-strong family covered by a GBP 1.5 billion, four-year Ministry of Defence funding line.

Type 93 sits in the same category as the US Navy's CAMP design, led by Kongsberg Discovery and Oceaneering International , making it a British parallel to a design effort now underway on the other side of The Atlantic.
