 FIRST Naval Construction Regiment


Welcome to the FIRST Naval Construction Regiment, "The BIG ONE". We are located in Port Hueneme, California on Naval Base Ventura County. The FIRST Naval Construction Regiment has over 50 years of commissioned service and has earned a positive reputation for innovation, responsiveness, and accomplishment. During peacetime, we exercise command and control over three commissioned Naval Construction Force (NCF) units: Naval Mobile Construction Battalions 18, 22, and 25. The FIRST Naval Construction Regiment and its subordinate units continue to play a vital role in the Pacific Fleet Seabees’ mission as well as operations in the CENTCOM and AFRICOM areas of responsibility. We are proud to serve as a crucial element of Naval Construction Group ONE and an integral part of the Navy’s Sea Strike mission.




We welcome you to our website.  Thank you for your interest in the Seabees and our command!
