Construction Battalion Maintenance Unit 303 Disestablished After Decades of Expeditionary Excellence

U.S. Navy Sailors, veterans and naval leaders gathered on board Naval Base Ventura County, Port Hueneme, to formally disestablish Construction Battalion Maintenance Unit (CBMU) 303 during a ceremony held in Needham Theater, Oct. 16, 2026.

The ceremony marked the conclusion of the unit’s operational service following the formal disestablishment notice approved by the Chief of Naval Operations, effective Oct. 1, 2026. As part of ongoing Naval Construction Force redesign initiatives, the maintenance and public works support functions historically provided by CBMU 303 and its Pearl Harbor detachment have been consolidated directly into Pacific Fleet Naval Mobile Construction Battalions (NMCBs).

U.S. Navy Capt. Andrew Litteral, commodore, Naval Construction Group (NCG) 1, presided over the ceremony and praised the unit's legacy.

“To the Sailors, past and present, of CBMU 303: Be proud of what you have built and what you have accomplished,” Litteral said. “Your blood, sweat, and craftsmanship are etched into bases, airfields, and installations across the globe. You kept the Fleet fighting, you lived the motto of ‘Can Do,’ and no change in organizational structure can ever erase the legacy of your service.”

U.S. Navy Cmdr. R.J. Uglow, the unit's final commanding officer who led CBMU 303 through its critical transition planning prior to his turnover in July, delivered keynote remarks reflecting on the command's heritage and its personnel.

"The true strength of CBMU 303 has always been its deckplate leaders, the tradesmen, mechanics, operators and support personnel who turned raw materials into critical infrastructure," Uglow said. "It has been the absolute privilege of my career to lead these fine Seabees. Though the watch is secured here today, their craftsmanship and devotion to duty have set a standard that will endure across the Naval Construction Force."

The disestablishment was punctuated by the traditional casing of the CBMU 303 colors and the formal order securing the command watch.

CBMU 303 traces its roots through numerous Pacific deployments, disaster relief operations and theater security cooperation exercises. While also providing essential public works maintenance, airfield damage repair support and shore facility contingency operations for Navy and Marine Corps operating forces.
