The F/CA/1933 design
The F/CA/1933 design is actually better protected, due to the "all-or-nothing" approach. Belt is 16ft high and 10ft longer. The torpedo bulkhead is a foot higher. The armour deck is now 2.5in. The armament is somewhat improved, as the 13cm guns are now dual-purpose, and the heavy AA guns (perhaps redundant) are now 10cm. There are more light AA guns, as well. The torpedo armament is now 8-21.6in TT. The roll period is greater: 15.2 seconds. This is the Springsharp report:]
