Gerard Michael Muller, age 44, passed away in May 2026. A devoted son, brother, shipbuilder, sailor, and friend, Gerard lived a life defined by service, dedication, leadership, and commitment to those around him.

Gerard spent much of his life serving his country and supporting his community. He proudly dedicated more than a decade to military service in the United States Navy and Naval Reserve, where he earned the rank of Machinist Mate First Class and served in numerous leadership roles. Throughout his military career, Gerard demonstrated exceptional professionalism and courage, serving aboard multiple submarines, including the USS CHARLOTTE (SSN-766), USS NEWPORT NEWS (SSN-750), and USS HYMAN G. RICKOVER (SSN-709). He qualified as a Subsurface Warfare Specialist, completed extensive damage control and firefighting training, and served as both a Team Leader and Scene Leader. During a deployment to Afghanistan, Gerard supervised 45 sailors and more than 350 detainees, earning the respect of those who served alongside him.

As a member of the Naval Research Laboratory's Live Fire Test Facility in Mobile, Alabama, Gerard helped develop and test firefighting and damage-control technologies designed to improve the safety and effectiveness of naval operations. His leadership as Engineering Department Leading Petty Officer, Safety Petty Officer, and Fire Party Team Leader reflected his commitment to excellence and the welfare of his fellow sailors.

Beyond his military service, Gerard built a successful career in the shipbuilding industry. As an Outside Machinist and Test Engineer with Huntington Ingalls in Pascagoula, Mississippi, he contributed to the construction and testing of United States Navy vessels, including destroyers, amphibious transport docks, and amphibious assault ships. He worked closely with shipbuilders and government personnel to ensure critical systems functioned safely and effectively, taking pride in helping build ships that would serve future generations of sailors.

Gerard valued education and lifelong learning. He graduated with honors from Mississippi Gulf Coast Community College, earning an Associate of Applied Science degree in Food Production and Management Technology. He later pursued a Bachelor of Science degree in Business Administration with an emphasis in Entrepreneurship at The University of Southern Mississippi.

Those who knew Gerard remember his strong work ethic, steady leadership, sense of duty, and willingness to help others. Whether serving his country, mentoring fellow sailors, building ships, or spending time with family and friends, he approached life with determination and integrity.

Gerard was preceded in death by his father, Kenneth D. Muller; his grandparents, Alfred and Hazel Muller; and John and Erika Norfleet.

He is survived by his loving mother, Jackie Muller; his brother and sister-in-law, Chris and Amber Muller; his sister and brother-in-law, Meggan Muller and Steve Morris; as well as numerous extended family members, friends, shipbuilders, and fellow service members whose lives were enriched by knowing him.

Gerard's legacy of service, leadership, and dedication will live on in the hearts of all who knew and loved him. He will be deeply missed, forever remembered, and always honored.
