UTILITIESMAN (UT)
The U.S. Navy Seabees (Naval Construction Force) utilitiesman rating — UT.
OVERVIEW
Utilitiesman (UT) is the U.S. Navy Seabees' plumbing, water, sewer, and HVAC rating. UTs install and maintain potable-water and waste-water systems, plumbing, fuel and steam distribution, water-treatment plants, and HVAC systems at Seabee projects worldwide.
The Seabees — the Naval Construction Force (NCF) — are the U.S. Navy's expeditionary engineers, building airfields, camps, bridges, roads, and piers in austere locations worldwide. Seabees deploy with Naval Mobile Construction Battalions (NMCBs), Underwater Construction Teams (UCTs), and Naval Construction Regiments. Their motto, "Construimus, Batuimus" — "We build, we fight" — captures their dual role.
A-school for the rating runs ~9 weeks at Naval Construction Training Center, Gulfport MS, where Sailors complete the technical foundation needed to report to their first fleet command. Entry requires the ASVAB line score AR+MK+EI+GS=200 and an enlistment obligation of 4–6 years. UTs advance through the standard enlisted paygrade structure (E-1 through E-9), competing in the Navy-Wide Advancement Examination (NWAE) at E-4 through E-6 and via the Selection Board at E-7 through E-9. Senior UTs typically serve as Leading Petty Officer (LPO), Work Center Supervisor, Leading Chief Petty Officer (LCPO), or Command Master Chief (CMC), and may pursue Limited Duty Officer (LDO), Chief Warrant Officer (CWO), or commissioning programs such as STA-21, MECP, or OCS.
Across the active force, UT Sailors are essential to the Navy's mission readiness, and the rating remains an in-demand career field with strong reenlistment bonuses (SRB), advancement opportunities, and pathways into Navy Reserve, civilian DoD, and industry careers after service.
WHAT UTs DO
UTs install plumbing, potable-water and waste-water systems, water-treatment and reverse-osmosis water-purification units, fuel and steam distribution, boilers, and HVAC systems at expeditionary base camps and permanent shore installations.
RESPONSIBILITIES
- UTs install plumbing, potable-water and waste-water systems, water-treatment and reverse-osmosis water-purification units, fuel and steam distribution, boilers, and HVAC systems at expeditionary base camps and permanent shore installations.
- Stand watches and qualify on the rating's Personnel Qualification Standards (PQS), maintain training jackets, and mentor junior UTs as required by the chain of command.
- Lead the UT work center as Leading Petty Officer or Work Center Supervisor — managing maintenance documentation in 3M/MFOM, parts ordering, and personnel qualifications.
- Support general military training (GMT), damage control, force protection, and watch-bill assignments common to every Sailor regardless of rating.
HISTORY
Utilitiesman was established during World War II within the Naval Construction Force to provide the utilities expertise needed for advance-base operations across the Pacific. The rating remains a core Seabee specialty.
The Naval Construction Force was established on 5 March 1942 by RADM Ben Moreell of the Civil Engineer Corps to provide militarized construction units for World War II — replacing civilian contractors who, under the laws of war, could not resist enemy attack. The Seabees built bases, airstrips, and pontoon causeways across the Pacific and Europe and have deployed in every conflict since.
Today the Utilitiesman (UT) rating is overseen by the Enlisted Community Management (ECM) office at My Navy HR and the Center for Personal and Professional Development. Modern UTs benefit from the Sailor 2025 personnel-system reforms, the Ready Relevant Learning (RRL) training continuum, and credentialing through the Navy COOL program — turning rating qualifications into industry-recognized certifications and licenses.
The rating's structure, training pipeline, and operational employment continue to evolve alongside the Navy's transition to Distributed Maritime Operations (DMO), Project Overmatch, and the Force Design 2045 fleet architecture, ensuring UTs remain central to the warfighting mission.
