Never Forget.

Today, NCB-18 joins our nation in remembering the lives lost on September 11, 2001.

25 years later, some still carry vivid memories of that day, while others know it through the stories and history passed down to them. Regardless of generation, we share the responsibility to remember.

We honor those we lost, the first responders who ran toward danger, and all who answered the call to serve in the years that followed.

NCB-18 remembers their sacrifice and honors their legacy.

We remember. We honor. We will never forget.

Our Seabees recently completed a specialized Planning and Estimating course focused on the Heavy Timber Bridge and SWA hut. During the training, they developed key skills in project planning and cost estimation, and learned how to put together a complete project package.

Not every contribution is measured in what gets built.
Throughout the AT on San Clemente Island, Seabees supported every corner of the mission. Crews offloaded the barge, restocked the galley, assisted with equipment maintenance, and worked alongside the galley staff to keep personnel fed and operations moving.

While these efforts may happen behind the scenes, they are essential to mission success. Every role mattered, and every Seabee helped keep the island running.

At San Clemente Islands, Seabees transformed a worn trailer into a functional living space through skilled craftsmanship and teamwork. From flooring and plumbing to new windows and a retrofitted kitchen and shower, every phase of the project challenged the crew to adapt as unexpected obstacles emerged.

The finished trailer reflects more than quality construction, it reflects the resilience, problem-solving, and teamwork that define our Seabees.

Our Seabees stationed at San Clemente Islands for AT accomplished many projects.

Here we have our road crew tasked to restore roads critical to island operations while strengthening the skills that keep our force mission ready. Working side by side, they trained on heavy equipment, learned new techniques, and tackled unfamiliar challenges with professionalism and determination.

The result was more than restored roadways. It was a team strengthened by shared purpose, hands-on experience, and the confidence that comes from accomplishing the mission together.

Things are moving at the RIMPAC Humanitarian Assistance and Disaster Relief camp!

The tent deck was completed, and Seabees are busy refueling generators to keep the power and A/C running. Monday morning an NCB 18 Equipment operator assisted some Expeditionary Surveillance Control Center personnel in positioning an important piece of equipment, meant to enhance our situational awareness. 👀

For 250 years, your story has been written by generations of Americans who believed in something bigger than themselves.

The Seabees have only been part of that story for a little over 80 years, but what a chapter it's been. Since World War II, we've built what others thought impossible, answered disasters, supported those on the front lines, and when called upon, fought beside them.

Today, another generation carries that legacy forward. The equipment has changed. The missions have changed. But the pride in serving this country hasn't.

As we celebrate America's 250th birthday, we remember the Seabees who built our legacy, honor heroes like Marvin G. Shields, and thank every veteran who helped shape the nation we know today.
