History

Originally having fewer officer ranks than the Army, the Navy previously split some of its ranks by seniority (time in rank) to provide equivalence: hence a lieutenant with fewer than eight years seniority wore two stripes and ranked with an army captain; a lieutenant of eight years or more wore two stripes with a thinner one in between, and ranked with a major. This distinction was abolished when the rank of lieutenant-commander was introduced in March 1914, although promotion to that rank remained automatic following eight years seniority in the rank of lieutenant. Automatic promotion was stopped in 2000, with the introduction of Pay2000The Armed Forces Pay Model, with promotion thereafter awarded only on merit.

Insignia

lieutenant commander is two half-inch gold braid stripes with one quarter-inch gold stripe running in between, placed upon a navy blue background. The top stripe has the ubiquitous loop used in all RN officer rank insignia, except for the rank of

. The RAF follows this pattern with its equivalent rank of squadron leader.

Royal Observer Corps

Throughout much of its existence, the British Royal Observer Corps (ROC) maintained a rank of observer lieutenant-commander. The ROC wore a

uniform and their rank insignia appeared similar to that of an RAF squadron leader except that the stripes were shown entirely in black. Prior to the renaming, the rank had been known as observer lieutenant (first class).
