The Leander class' design was to have sides that would be impervious to 6" shells fired greater than 10,000 yards.
It was thought that the Leander class cruisers might be operating on their own in the shipping lanes.
The Leander was ordered in the 1929 Program. The Achilles, Neptune, and Orion were ordered in the 1930 Program. The Ajax was ordered in the 1931 Program.
Due to modifications during the construction of the Leander the followup ships had a wider beam.
Welding was used throughout the construction of the Leander class ships.
The cost was £1.5 million - £1.6 million each.
There was a single catapult to launch the aircraft.

There was only a single firing director installed so it was impossible to coordinate firing on more than one target at a time.
There were two turbine and three boiler rooms. The uptakes went to a large funnel.
