Everyone is a little down on 'coastal' diesel-electric type
subs...but in a non-time limited anti-surface role such as
the Falklands I would prefer to use a modern diesel to a
nuclear propelled HK.
The nuclear plant provides real advantages in deployment
and speed but the submarine itself is far larger and
inherently noiser than a 'littoral defense' type diesel
sub.
My two pennyworth,
