An item referred to the magazine USR dated 31 August 1939 reporting that the British cruiser HMS Coventry and Curlew were fitted out with an anti aircraft armament consisting of 10-10,5cm/4.1” guns and 11 smaller guns. The Calcutta and Cairo were fitted out with 8-10,5cm guns and probably were the Capetown, Carlisle, Colombo and Curacao to be armed in similar manner. The Penelope-class cruisers with a main armament of 6-15cm/5.9” guns had also an anti aircraft armament of 8-10,5cm guns. It was the intentioned to convert also all D-class cruisers into anti aircraft cruisers.
