Waterjets

As the world leader in waterjet propulsion, Rolls-Royce provides solutions for customers around the world. Our Kamewa waterjets power the smallest inshore craft up to the largest ferries and the latest high speed naval craft.

Aluminium waterjets

Kamewa FF and A-Series, powers from 100kW to 2,800kW

Stainless steel waterjets

Kamewa S3 and SL Series, powers from 1,000kW to over 40MW.

Our Kamewa range is the broadest in the business. Manufactured in aluminium and stainless steel, power requirements from 100kW to over 40MW can be met to suit virtually any application.

Waterjets are in a class of their own because of their versatile operating characteristics, which permit easy and accurate control of the craft at all speeds and in waters too shallow for vessels with conventional propulsion systems.

At high speeds, the unrivalled efficiency of waterjet propulsion offers either a greater top speed or better fuel economy. No reversing gearbox is required, stopping distances are short and craft can turn on the spot or even manoeuvre sideways.

Rolls-Royce pioneered the application of waterjets in naval vessels and ongoing research and development with the US Navy has resulted in the AWJ-21, an underwater discharge waterjet design with remarkable stealth characteristics.
