WORKERS get to grips with a huge propeller for the first of the new aircraft carriers in construction for the Royal Navy.

Each ship will have two propellers, which together will be capable of generating 50,000 horsepower – enough to run 1,000 family cars or 50 high speed trains.

The nickel-aluminium-bronze propellers have been built by Rolls Royce in Sweden, where this photo was taken.

Each one is more than seven metres wide and weigh 33 tonnes – two and half times as heavy as a double-decker bus.

The new carriers, HMS Queen Elizabeth and HMS Prince of Wales, will be based in Portsmouth later this decade. Portsmouth Harbour is being dredged to accommodate them.
