Naval Mobile Construction Battalion 133 — Built to Build. Trained to Fight.

The Naval Mobile Construction Battalion 133 (NMCB-133) is part of an elite lineage of Seabees — the U.S. Navy's legendary construction warriors who have built airstrips under fire, erected field hospitals in remote jungles, and kept the mission moving when it mattered most. This premium tee is a tribute to every Seabee who wore the NMCB-133 patch with pride.
