The Crete campaign forced the Royal Navy to improvise while covering an evacuation under sustained air attack. Dido-class ships supplied heavy AA fire while also serving as screening cruisers in fleets short of destroyers. Between 15 and 27 May, Royal Navy AA claims of 20 confirmed kills, 11 probables, and 15 damaged aircraft broadly matched the listed Axis losses. Shortages of Merlin-engine spares reduced Formidable's available fighter strength and shifted more defensive work onto ships such as Dido. The pressure on close escorts is illustrated by the Tribal-class destroyer Nubian steering home on her propeller shafts after losing her stern and rudder.
