⚓️ ACB-1 had an incredible time at Los Angeles Fleet Week!
We connected with the community, showcased our mission and capabilities, and joined fellow service members in celebrating the maritime services and the people who support them. We were honored to be part of such a memorable event and grateful to everyone who stopped by to visit.

Thank you to everyone who stopped by, asked questions, and shared in the experience. Events like these strengthen the bond between our military and the communities we serve. Until next year, Fleet Week! ⚓️🌊
