Naval rank

During the early days of the naval rank, a lieutenant might be very junior indeed, or might be on the cusp of promotion to captain; by modern standards, he might rank with any army rank between second lieutenant and lieutenant colonel. As the rank structure of navies stabilized, and the ranks of commander, lieutenant commander and sub-lieutenant were introduced, the naval lieutenant came to rank with an army captain (NATO OF-2 or US O-3). The insignia of a lieutenant in many navies, including the Royal Navy, consists of two medium

Lieutenant commander

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 Royal Navy followed suit in March 1914. The insignia of an additional half-thickness stripe between the two full stripes of a lieutenant was introduced in 1877 for a Royal Navy lieutenant of 8 years seniority, and used for lieutenant commanders upon introduction of their rank.
