is already supplying
propulsion equipment on the first two Lockheed Martin vessels. This latest contract extends this with one firm order and options for a further nine ships of the same design. Te MT30 is derived from Rolls-Royce
aero engine technology, building on more than 45 million hours of operating experience and reliability. It also has the highest power density of any marine gas turbine – a key factor in naval propulsion where delivering a high power output in a compact space is essential.
