The M and N class destroyers are basically improved I/J class types with heavier AA (double the original design) and slightly more shell capacity for the main guns.

L class, Atlantean Destroyer laid down 1936

As done with the M/N class in regards to their improvements over their predecessors (I/J class) the L class destroyers represent a similar design process when designers looked to improve on the K class. Their AA was increased as well as their electronics outfit. While the K's did away with torpedo reloads the L class reverted to the standard modern destroyer outfit at the expense of half their depth charge capacity, landing their depth charge throwers and reducing the number of depth charges carried.

A refit is planned for these ships to extend their service life when funds and shipyard space becomes available, most likely when M class ships are completed. During their original design process the 5.5" gun was considered for their main armament but the new 5.1" Mk 1 gun was chosen instead.
