Current service use not established
This code is listed in the directory. Inclusion alone does not confirm current service use.
A Navy officer classification, not an enlisted rating.
Overview
A Supply Corps Limited Duty Officer performs technical and management duties in supply, finance, inventory control, contracting, distribution, and material logistics. They may also work with computer systems, operations analysis, petroleum management, food services, and budgets while serving with ships, submarines, shore commands, or joint organizations.
Notes & Sources
- NOOCS Part A (Edition 96, Jul 2026) prints officer code 651X as “A Limited Duty Officer of the Supply Corps…”, paired with its Limited Duty Officer billet row (billet 6510 requiring the specialty); the row states who holds the code and which specialty the billet requires, not what duties every holder performs. See the cited block for the exact pairing text.
- Because the Navy carries no duty, training, or clearance prose at designator level, occupation-specific recommendations are not published here; a 651X officer’s duties depend on the assigned billet.
