612X Operations (Surface) LDO
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 surface operations limited duty officer manages the operation, employment, and application of operations and communications equipment, systems, techniques, and procedures. The officer plans and directs operations and communications activities, trains personnel, advises commands, and may serve in combat information, warfare, combat systems, or tactical action assignments.
Notes & Sources
- NOOCS Part A (Edition 96, Jul 2026) prints officer code 612X as “A Limited Duty Officer…”, paired with its Limited Duty Officer billet row (billet 6120 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 612X officer’s duties depend on the assigned billet.
