At Weymouth Roads 28 May "McCook" was caught in an air raid in which she suffered damage to her radar, sound equipment, range finder, and main battery director in addition to having five guns disabled and losing steering control from the bridge. Luckily there were no personnel casualties. The damage threatened to keep her out of the upcoming invasion for which she had been training for the past month. But the fast and efficient craftsmen on board the destroyer tender quickly had her back in fighting trim.
