Navy’s £1bn high-tech destroyers break down in warm water

The British military’s supposedly cutting-edge Type 45 destroyers are effectively overheating and shutting down outside of cold waters, the Defence Select Committee has heard.

On Tuesday defense chiefs admissions to committee suggested that the program is not as successful as made out. This is despite years of downplaying the vessel’s failures as mere teething problems.

They told the committee that the Type 45s could not handle warm waters and would have their apparently sub-standard Rolls-Royce WR-21 gas turbines replaced with diesel generators.

    Gee, guess what Trudeau will be buying.

    Haven’t read the piece yet but I wonder if the gas-turbines rather than diesel choice was motivated by enviro-crap?

    Addendum: doesn’t say.

      I think gas turbine engines have been used on warships for a long time. Someone must have screwed up big time with the engineering here if they have to go as far as changing out the entire engine.

        Thanks for the info. I was thinking it because the Americans’ air forces have some green fuel crap regulations and thought it might have been similar.

      The WR-21 GT uses a heat exchanger to cycle heat from the exhaust back into the engine, which increases the fuel efficiency. Someone used the wrong numbers to size the heat exchanger and now the main turbines overheat and shut down. The ship has an integrated electrical system, which powers everything including the propellors. Apparently, the diesel generators have insufficient excess capacity to take on load load when the GT generator shuts down.
      The Halifax frigates cruise on diesel with the GTs for sprinting.

    amateurs … Wynne could sleep walk that screw up

    for god’s sake why are the Brits STILL using lucas parts ? he really was the lord of darkness you know, still how about we magnanimously offer to trade the cold water hungry boats obviously designed for Canadian waters, as a straight accross fair trade for the dented sub they fobbed off on us ?.

      Jags , MGB , & warm beer

        Jags that take 28 litre oil changes because, due to under engineered rads and water cooling, they need cooled oil to avoid seizing up and every 4000 miles you have to dump the oil, now, i admit lord Lucas (the obscure) is not liable for that engineering bollocks, just creeping British torpitude that was pushed aside briefly under Thatcher then was snuffed out, forever under a swamp of multiculti.

    How do they store enough gas to run that thing?
