Overview

A SEAL Delivery Vehicle MK-8 and MK11 Pilot conducts tactical Naval Special Warfare and unconventional warfare operations while piloting wet combat submersible platforms below the surface in denied environments. The pilot implements quality assurance procedures, performs parachuting and explosives demolition, and uses all types of underwater breathing apparatuses operationally.

Core Skills

  • Operational use of underwater breathing apparatuses
  • Implementation of quality assurance procedures
  • Explosives demolition and parachute operations

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Commercial Divers

Operational qualification with underwater breathing apparatuses and experience piloting wet combat submersibles provide a foundation for commercial underwater work.

How to prepare: Have a commercial-diving employer assess your existing qualifications, military training records and dive logs against its assigned tasks and OSHA 1910.410, identifying only gaps that need further training. For work covered by that standard, qualifications must address task-specific equipment, diving mode and emergency procedures, CPR and first aid, plus diving physics and physiology for personnel exposed to or controlling hyperbaric exposure.

What the civilian work involves
  • Take appropriate safety precautions, such as monitoring dive lengths and depths and registering with authorities before diving expeditions begin.
  • Descend into water with the aid of diver helpers, using scuba gear or diving suits.
  • Obtain information about diving tasks and environmental conditions.
Civilian tools and software (examples)
  • Diving logbook software
  • Diving table software

Notes & Sources

  • If pursuing an ADCI card, seek assessment of existing training for recognized equivalence: its Entry Level classification requires 625 documented hours of formal instruction or a recognized equivalent. Its Air Diver classification requires 100 field days and 30 working dives, with only surface-supplied dives counting toward the requirements. These are ADCI program standards, not a universal government license.
