The corresponding rank in most armies, (armed services) and air forces is Major, and in the Royal Air Forceand other Commonwealth air forces is Squadron Leaderalso.
A Lieutenant Commander is a senior department officer on a large
shipor shore installation. They may also be commanding officeror executive officer( second-in-command) of a smaller ship or installation.
Lieutenants were commonly put in command of smaller vessels not warranting a Commander or Captain: such a Lieutenant was called a "Lieutenant Commanding" or "Lieutenant Commandant" in the
United States Navy, and a "Lieutenant in Command" or "Lieutenant and Commander" in the Royal Navy. The USN settled on "Lieutenant Commander" in 1862, and made it a distinct rank; the RN followed suit in March 1914.
The insignia worn by a
Royal NavyLieutenant-Commander (Lt Cdr) is two medium gold braidstripes with one thin gold stripe running in between, placed upon a navy blue/black background. The top stripe has the ubiquitous loop used in all RN officer rank insignia. The RAF follows this pattern with its equivalent rank of Squadron Leader.
Having fewer officer ranks than the army, the RN 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, the new rank taking the insignia and army equivalence of a senior Lieutenant.
Similar insignia is worn by Lieutenant-Commanders in other Commonwealth navies, such as the
Royal Australian Navy(which uses the abbreviation "LCDR"), the Royal New Zealand Navyand the Canadian Forces Maritime Command(formerly the Royal Canadian Navy; which uses the abbreviation "LCdr"). Unlike the United States Navy, personnel in the Royal Navyor other Commonwealth Navies addressing a Lieutenant-Commander do not abbreviate the rank to "Commander."
Royal Observer Corps
Throughout much of its existance, the
Royal Observer Corpsmaintained a rank of Observer Lieutenant Commander. The rank insignia was similar to that of an RAF squadron leader except that the stripes were shown entirely in black.
The corresponding rank to Lieutenant Commander is Captain 3rd Rank.
