What is the rank of a Navy officer who wears 1 silver star insignia?

The rank of a Navy officer who wears 1 silver star insignia is Rear Admiral Lower Half. In the Navy, the insignia system designates ranks with gold or silver stars to denote levels of seniority. Specifically, a silver star is representative of the rank of Rear Admiral Lower Half, which is equivalent to a one-star admiral. This insignia is distinct and different from other ranks, such as Commander, Captain, or Lieutenant Commander, which do not utilize the silver star designator in their insignia.

Commander typically features a gold oak leaf insignia, whereas Lieutenant Commander is denoted by a silver oak leaf. Captain is represented by a silver eagle insignia. Therefore, the presence of 1 silver star is specifically indicative of the Rear Admiral Lower Half rank, clarifying its unique position within the Navy’s ranking structure.
