A detail from the Navy Ceremonial Guard performed a Gun Salute in honor of former President George H.W. Bush along the waterfront at the Washington Navy Yard Tuesday.

The first round was fired immediately following Morning Colors at 8 a.m., echoing along the shores of the Anacostia River. Following that, a round was fired every 30 minutes until Evening Colors at 4:46 p.m. The last round was fired at 4:30 p.m. for a total of 18 rounds.

The gun salute was one of the first military honors visible to the public in Washington D.C. for former President Bush, a decorated Navy pilot during WW II who passed away Nov. 30 at his Houston, Texas home at the age of 94.

Established in 1931, the United States Navy Ceremonial Guard is the official ceremonial unit of the Navy. Located at Joint Base Anacostia-Bolling, Washington, DC, the Navy Ceremonial Guard’s primary mission is to represent the service in Presidential, Joint Armed Forces, Navy, and public ceremonies in and around the nation’s capital.
