What are a Lieutenant's Responsibilities?

A Lieutenant is the third rank among officers in the USN. This is not to be confused with LTs of the Army, Marines, and Air Force, who are O-1s and O-2s.

The expectations for a LT are ever higher than for a LTJG. At this point, the officer is expected to be fully warfare qualified and demonstrate sufficient leadership qualities as to take charge of tactical watch teams and casualty situations. They are the principal mentors of Junior Officers and provide much training and direction for the rest of the crew. On a ship, they can make emergency decisions on behalf of an absent Commanding Officer, such as sailing the ship underway from port if a damaging storm is imminent. They may even be Commanding Officers or Officer-in-Charge (OIC) for small ships or units -- like a SEAL Platoon or small Naval Support Activity (NSA).

In most communities, Lieutenants achieve their rank shortly before leaving their first sea-going command, then work at a shore-based command for two years before going to Department Head training and their next sea-based assignment. LTs then serve as Department Heads, responsible for a collection of related Divisions (e.g. Combat Systems, Engineering, Supply), and may promote to the next rank during this tour.

In the Direct Commission Officer community, LTs are fully qualified professionals, such as MDs, JDs, or PhDs.
