- Prefix to a grade, rank, rate, or title, indicating that it is temporary and that the incumbent may not be fully-qualified for the post. acting sub-lieutenant: appointed by order rather than commissioned, this subordinate officer rank was introduced by the rn in 1860 to replace those of acting mate and passed midshipman. after completion of qualifying courses they were commissioned as sub- lieutenants. their status was somewhat nebulous until 1894 when admiralty order in council no.41 defined them as being “to all intents and purposes sub-lieutenants ... being merely styled ‘acting’ until they have passed the final examination for lieutenant.” the title fell into abeyance after the first world war, but in 1955, probably to introduce a closer equivalent to usn ensign, the royal and commonwealth navies re-instated it as a substantive rank, separate from and junior to sub-lieutenant. in 1993, the rn abolished the rank in regular service, but it continues in the royal naval reserve and in the canadian and australian navies. a similar rank exists in the pakistani navy.
