Parliament has been assured that the Type 26 Frigate fleet will not suffer the same propulsion issues as the Type 45 Destroyers.
The propulsion system of the frigates will have a gas turbine direct drive and four high speed diesel generators driving two electric motors in a CODLOG configuration. In 2012 Rolls Royce repackaged the MT30 used in the Queen Elizabeth class aircraft carriers so that it would fit into smaller ships, the Type 26 will use the MT30 a different engine than the one used by the Type 45’s.
In June, the MoD admitted that the Type 45’s were breaking down because the Northrup Grumman intercooler could not cope with the warm waters of the Gulf. Manufacturers Rolls-Royce of the fully functioning, non-problematic turbines said that the intercoolers for the WR-21 had been built as specified, but that conditions in the Middle East were not “in line with these specs”.
Type 26 is not expected to have these issues at all.
Flick Drummond (MP for Portsmouth South) asked:
“To ask the Secretary of State for Defence, what steps he is taking to ensure that the Type 26 frigate will be able to operate across the full range of climatic conditions in which the Royal Navy operates.”
Answered by Philip Dunne:
“The Type 26 Global Combat Ship will be designed for joint and multinational operations from the tropics and Arabian Gulf in the summer to the sub-Arctic. The ship’s design will accommodate a broad range of environmental conditions to deliver a globally deployable ship throughout its planned life.
I am withholding further detail as disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.”
The Type 26 is due to replace the navy’s ageing fleet of 13 Type 23 frigates.
