I've uploaded a feature article on the British J-Class destroyer, which
greatly expands on the 'briefing' that's already on the site. You can find
it in the British Ships section.

Perhaps the most important British destroyer design of the war, this ship
formed the foundation of the 'War Emergency' program. 124 ships entered
service based on this type, they served all over the world and were operated
by the Australian, Canadian, Netherlands, Norwegian and Polish navies, as
well as the British.

Enjoy!
