HMS Dragon is undergoing “planned maintenance” in advance of further operational commitments.
Mr Quin told MPs on the committee: “We have two Type 45s embarked with the CSG, Diamond has got current issues but I hope they will be able to be rectified shortly.”
Mr Ellwood said: “HMS Defender is now our only current operational Type 45.
“If that ship experiences propulsion problems as we have seen across the Type 45 family, then our carrier group would have to be forced to lean on a Nato ally to ensure that we have destroyer protection.
“That really indicates – bottom line – we need a bigger navy.”
