The Combined Joint Operations from the Sea Centre of Excellence (CJOS COE) was established in May 2006, to provide a focal point for Joint Maritime Expeditionary Operations expertise for allied nations. With 13 nations represented, CJOS COE is the only Centre of Excellence in the United States, and is one of 20 NATO accredited Centres worldwide, representing a collective wealth of international experience and expertise, and best practices.

Independent of the NATO Command Structure, CJOS COE draws on the knowledge and capabilities of Sponsoring Nations, United States Fleet Forces, and neighboring U.S. Commands to promote “best practices” within the Alliance. CJOS COE also plays a key role in aiding NATO’s transformational goals, specifically those focused on maritime-based joint operations. We enjoy close cooperation with Allied Command Transformation (ACT), other maritime COEs, NATO Joint Forces Commands, various national commands, academia. 

With almost 30 permanent staff and 20 USN reservist, CJOS COE is highly flexible and responsive to its customers' needs.  The Centre has worked to reduce consultations between COE staff and key exports within individual Sponsoring Nation and other customers setting up “Focal Points of Contact” that put the Centre directly into contact with their Subject Matter Experts
