The Aircraft Carrier Alliance fitted the Rolls-Royce MT30 into the Royal Navy's latest aircraft carrier which is a 36 megawatt (around 50,000 horsepower) Marine Gas Turbine.

The GTA is also the world's most power-dense, a key feature for naval ships where high power occupying space is essential.

Each 120 tonne GTA package consists of GE supplied alternator coupled to a Rolls-Royce supplied MT30 Gas Turbine contained within an enclosure.

Two MT30s are installed in each ship and will provide two thirds of the 109 megawatts needed to power the 65,000 tonne ship – enough energy to power a town the size of Swindon!

Jim Bennett, power and propulsion director for the Aircraft Carrier Alliance, said, "The Power & Propulsion Sub-Alliance is immensely proud of this significant milestone in the QEC project. It has been the culmination of many years of hard work to ensure the timely delivery of this first complete MT30 gas turbine alternator to HMS PRINCE OF WALES, which along with its twin will deliver around two thirds of the electrical power generated onboard. Congratulations to all involved, this is British engineering at its best!"

Angus Holt, delivery director, HMS PRINCE OF WALES, said, “The successful achievement of this major milestone is symbolic of the progress we are making with the build of the second Queen Elizabeth Class carrier.

“To have successfully lifted the most powerful engine in the Royal Navy onto the biggest ship ever built for the Royal Navy, using one of the biggest capacity gantry cranes in Europe, is an important event in the construction of HMS PRINCE OF WALES. Everyone involved should take huge pride in their contribution to this national endeavour.” Don Roussinos, Rolls-Royce, President - Naval said, “We installed the very first marine gas turbine more than 60 years ago, and are delighted to continue that long and proud history of delivering advanced marine gas turbine and propulsion technology to the Royal Navy.”
