NORFOLK – Rear Adm. Dan Lannamann relieved Rear Adm. William Greene as Commander, Navy Regional Maintenance Center (CNRMC) at Naval Station Norfolk, Virginia, during a ceremony presided over by Vice Adm. James P. Downey, commander, Naval Sea Systems Command (NAVSEA), March 12.
Prior to transferring command to Lannamann, Greene served as commander for both CNRMC and Surface Ship Maintenance, Modernization, and Sustainment (NAVSEA 21) since Aug 2023. Under his leadership, the organization has transformed how the Navy plans and executes depot availabilities. On-time completion rates for Chief of Naval Operations depot availabilities climbed from 41% in fiscal year 2023 to 65% in fiscal year 2024. Greene also implemented surface maintenance acquisition strategies that help evolve and enhance repair capabilities and improve operational readiness.
“This is a great day for the Surface Sustainment Enterprise, and I want to thank Vice Adm. Downey for his leadership in championing this positive change. We have a great team working on surface maintenance, modernization, and sustainment challenges and this will allow additional focused leadership attention in these critical areas,” said Rear Adm. Bill Greene. “Going forward, SEA 21 and CNRMC will remain closely coupled and I’m looking forward to working with Dan to continue to drive progress on key improvement initiatives across the board.”
This formal return to separate leadership enables the CNRMC commander to focus on initiatives and actions to optimize readiness generation, a key line of effort in NAVSEA’s Enterprise Strategy. Lannamann is an Engineering Duty Officer, who most recently served as the Acting Commanding Officer, U.S. Naval Ship Repair Facility and Japan Regional Maintenance Center. His previous assignments include Commanding Officer, Mid-Atlantic Regional Maintenance Center; Executive Director, Navy Regional Maintenance Center; and Program Manager, Carrier Planning Activity. As commander, Lannamann will build on CNRMC’s progress to optimize availability processes and continue to drive rigor and efficiency within the surface maintenance enterprise.
Lannamann noted that the people of CNRMC are the heart and soul of the command and their excellence is foundational to the organization’s success. “Together, we deliver material readiness essential to the Navy’s ability to fight and win,” said Lannamann. “Combat readiness starts with all of you. We—this command and the Navy’s Regional Maintenance Centers—exist to ensure the on-time delivery of fully mission-capable combat warships.”
The two offices will remain closely aligned in support of the surface sustainment enterprise as Rear Adm. Greene continues to serve as the director for NAVSEA 21.

“No discussion of the world’s most powerful surface Navy can begin without reflecting on the work of SEA 21 and the RMCs,” said Downey. “Their expertise and skill continue to keep our surface fleet modernized, maintained and sustained, enabling them to deploy and to stay at sea to meet their mission. It is because of these teams that our surface ships are in the fight."
CNRMC oversees the operations of RMCs in their execution of surface ship maintenance, modernization and sustainment. The RMCs, located in Norfolk, Virginia; Mayport, Florida; San Diego; Naples, Italy; Rota, Spain; Manama, Bahrain; and Sasebo and Yokosuka, Japan; and Singapore, are responsible for coordinating depot- and intermediate-level maintenance of the Navy's surface fleet.
CNRMC is also responsible for the coordination of contracts management and oversight, technical assist, and intermediate-level maintenance activities at Northwest RMC at Puget Sound Naval Shipyard, Washington; and Hawaii RMC, embedded in the Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility.
SEA 21 is the dedicated life-cycle management organization for the Navy's in-service surface ships and is responsible for managing critical modernization, maintenance, training and inactivation programs. SEA 21 provides wholeness to the Fleet by serving as the primary technical interface, ensuring surface ships are modernized with the latest technologies and remain mission relevant throughout each ship's service life. The organization also maintains inactive ships for future disposal, donation, or transfer, to include follow-on technical support to our partner navies.
