Second of Algarves heavy cruiser classes, the four ships of the Torquay class were a major advance despite having similar dimensions and a comparable hull layout to the previous Penzance Class.
Numerous alterations were made between the two classes. The new Mk.XIV BD 4 twin turret was fitted hot off the press as it only entered service in 1934 just in time to be placed aboard the Torquays with two new HACS directors to control them. A new triple 8 and Director control units were fitted. The hangar was resited from around the after funnel to around the fore funnel. Slightly larger propulsion system, increased from 75,000 to 80,000 shaft horsepower which increased the speed from 31.5 knots to 32 knots, despite a bit of extra weight and breadth. Many more minor alterations made to enhance the ships over the previous class.
