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 with the introduction of ‘Pay2000’ and promotion is now only awarded on merit.
