Aviation Standard Test Battery-E (ASTB E) Practice Test

The role that qualifies to command ships and aviation units is the Unrestricted Line Officer. This designation is essential within the Navy, as it encompasses officers who are trained in both surface warfare and aviation, allowing them to take command of naval vessels and aviation squadrons. Unrestricted Line Officers have a broad range of operational responsibilities and can advance to senior leadership positions where they oversee significant naval operations. Their training includes comprehensive learning in tactics and procedures relevant to commanding both ships and aircraft, ensuring they are equipped to handle the command of diverse naval units.

Other roles such as the Weapons System Officer focus on specific areas in aviation and do not have the broad command capabilities of Unrestricted Line Officers. The Executive Officer generally serves as the second-in-command, assisting the commanding officer but typically does not hold complete command authority themselves. The Chief of Naval Operations is the highest-ranking officer in the Navy and is focused on overall strategic directions rather than direct command of individual ships or units.
