Abstract : The United States Navy, while releasing "A Cooperative Strategy for 21st Century Seapower," does not have doctrine specifically written to address the issue of piracy. The U.S. Navy uses a Concept of Operations (CONOPS) to show how capabilities could be used to accomplish an objective, but this may not be enough given this newly published maritime strategy. The Navy needs to take charge of its doctrine development and not wait for piracy operations to be promulgated as formal Joint Doctrine from the Joint Staff. Writing doctrine would support the newly written. "A Cooperative Strategy for 21st Century Seapower," which stresses a unified maritime doctrine that integrates the sea services. A written doctrine would clearly delineate responsibilities, allow for consistent training, and codify vocabulary. Most important, writing Naval Doctrine for anti-piracy operations would provide for repeatable and proven procedures in this critical area of keeping the sea lanes open for global commerce.
