Navy Rear Adm. Mark D. Behning nominated for promotion to vice admiral
The Undersea Warfare Division director would become deputy commander of U.S. Fleet Forces Command in Norfolk, Virginia, if the Senate confirms the three-star nomination.
Navy Rear Adm. Mark D. Behning drew a nomination for promotion to vice admiral, a move that would place him at the command that mans and equips much of the U.S. fleet.
The Department of War announced the nomination July 16, 2026. Behning would serve as deputy commander, U.S. Fleet Forces Command, and commander, Task Force EIGHT ZERO, in Norfolk, Virginia. He currently directs the Undersea Warfare Division, N97, within the Office of the Chief of Naval Operations at the Pentagon in Washington, D.C. The nomination requires Senate confirmation before it takes effect, according to Google.
U.S. Fleet Forces Command organizes, mans, trains and equips naval forces for combatant commanders, and it sets fleet warfighting and readiness requirements for the chief of naval operations, according to wikipedia.org. The command deters, detects and defends against homeland maritime threats as the Navy’s service component to U.S. Northern Command, according to wikipedia.org. Its deputy commander sits at the center of that force-generation mission, overseeing readiness and deployment for forces that operate worldwide. A third star would place Behning among the small tier of senior flag officers who shape how the Navy readies ships, submarines and aircraft for global operations. Task Force EIGHT ZERO adds an operational command to the assignment, tying the deputy role to fleet employment as well as force provision.
Behning’s undersea warfare background aligns with the command he would help lead. As N97 director, he oversaw submarine and undersea programs for the chief of naval operations, a portfolio central to the Navy’s deterrence mission. The move to Norfolk would shift him from resource planning toward the readiness and force-generation work that defines U.S. Fleet Forces Command. For most Americans, the appointment sits far from daily life yet touches the machinery that keeps sea lanes open and homeland maritime defenses staffed. Fleet readiness determines how quickly carrier strike groups and submarines can deploy in a crisis, a national security factor that rarely surfaces in public view.
Submarine officers have moved into this seat before. The deputy commander post routinely draws senior officers from across warfare communities, and aviators, surface warfare officers and submariners have led and deputized the command across its history. Adm. Karl O. Thomas currently commands the force, according to wikipedia.org. The Senate Armed Services Committee reviews flag officer nominations before the full chamber votes, and a date for a confirmation vote has not been announced.
The command carries a long lineage that predates the modern Navy’s global reach. It began as the United States Atlantic Fleet, which President Theodore Roosevelt established on Jan. 1, 1906, alongside the Pacific Fleet, to protect Caribbean bases gained after the Spanish-American War, according to wikipedia.org. Rear Admiral Robley D. Evans became its first commander, hoisting his flag in the battleship USS Maine, and the next year he led 16 battleships known as the Great White Fleet on a round-the-world cruise that ran until 1909, according to wikipedia.org. The Atlantic Fleet took the name United States Fleet Forces Command on May 25, 2006, reflecting a post-Cold War focus on scalable readiness, according to grokipedia.com.
