The "Tiger" design had a broader beam from on which to accommodate the larger turrets. But it was preferred to complete "Superb" with the older Mk 23 turrets in 1945, a 64 ft beam 'Swiftsure'. The 1942 "Tiger" design was redesigned with better protection and internal division to take advantage of a three turret design with four 40 mm "Stabilized tachymetric anti-aircraft gun" (STAAG) for close defence with Type 262 radar, AIO, and more pumps and generators. However, by early 1944 it was obvious the turret weight, crewing, and electrical requirements of the "Tiger" design required a larger design. By March 1944 "Defence" and "Blake" were all but signed off for transfer to the RAN to be completed as 5.25-inch gun cruisers. British production of 5.25 turrets was slow and little work was done on the cruisers other than to launch "Defence" in September 1944. The fact that they were years from commissioning guaranteed Australia rejected the deal.
