720X Diving Officer CWO
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
Diving Officers lead manned and unmanned diving and hyperbaric operations at sea and ashore, including underwater ship husbandry, salvage, special warfare, and undersea research and development missions. They supervise diving methods and hyperbaric systems, manage diving program administration and life-support system certification, oversee operational risk and procedural compliance, and advise on manpower, equipment, requirements, and policy.
Notes & Sources
- NOOCS Part A (Edition 96, Jul 2026) prints officer code 720X as “Diving Officer…”, paired with its Chief Warrant Officer billet row (billet 7200 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 720X officer’s duties depend on the assigned billet.
