What rank follows Rear Admiral Lower Half (RDML) in seniority?

The rank that follows Rear Admiral Lower Half (RDML) in seniority is Rear Admiral Upper Half (RADM). This is because the naval rank structure is hierarchical, and RDML is the junior of the two Rear Admiral ranks.

The hierarchy in the rank structure places RDML as a one-star admiral, while RADM is a two-star admiral. This means that RADM has greater seniority and authority than RDML. After RADM, the rank of Vice Admiral (VADM) follows, which is a three-star rank, but the immediate progression from RDML is to RADM.

Understanding the progression of ranks is essential in military operations where chain of command and authority levels are crucial for effective leadership and decision-making.
