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
Explosive Ordnance Disposal Limited Duty Officers lead and manage explosive ordnance operations, expeditionary diving, and the elimination of explosive threats on land and in waterways. They conduct operations in contaminated environments, support special operations, plan missions, oversee command and control, manage training, and evaluate combat readiness.
Notes & Sources
- NOOCS Part A (Edition 96, Jul 2026) prints officer code 648X as “A Limited Duty Officer…”, paired with its Limited Duty Officer billet row (billet 6480 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 648X officer’s duties depend on the assigned billet.
