Back to Commonwealth Ships List
The Leander class were important that they marked the return of the 6"
cruiser after ten years of the Treaty heavy cruisers. The British Empire
requires large numbers of cruisers, quantity rather than size. An 8000 ton cruiser
meant they could build 3 6" cruisers for the price of 2 of the County types. A
basic armament of 9 x 6" in triple turrets was deemed sufficient for this class
with first single 4" as the heavy AA, these being replaced by twin 4" as they
became available and as the ships went for refits. The ships were ordered in
four groups of four. The first RN group completing in 1932-33, the Australis
group in 1934-35, the next RN group in 1935-36 and the Southern African ships in
1936-37.
The four ships built for the Southern African Navy were the last overseas
built cruisers for the SAN. From this class onwards the SAN built its own
designs (with mixed results). With upright funnels and compact bridges these ships looked magnificent and
served in theaters throughout the world. Several being lost (I am just not sure
which ones yet and how).
Between 1939 and 1941 all of the ships that survived had electronic aids fitted
for all the different levels of armament. Sea search and Air search radar were a
must and improvements to these and other radars meant upgrades being put aboard
the ships at regular refit intervals. The extra topweight from the electronics
and extra AA weaponry meant the removal of the torpedoes and aircraft handling
facilities to balance things out
