 Each spring, naval and industry leaders gather at National Harbor for the Sea Airspace Expo. This conference gives leaders from around the globe a chance to interact with and see the best that the defense industry has to offer. Game changing technology is the theme of this year's Expo, and members from the Cyber, Electromagnetic and Information Dominance fields are displaying a variety of unmanned aerial vehicles and unmanned undersea vehicles. If you can't make it to the Expo, check out their website. On April 11th, two annual ceremonies took place in Washington, D.C., the Cherry Blossom Festival and the blessing of the fleet. In a centuries-old tradition created in Europe, sailors from the U.S. Navy's ceremonial guard poured water from the Seven Seas and the Great Lakes into the Granite Sea Fountains at the Navy Memorial to charge them to life. The ceremony ushers in the spring season and is believed to protect ships and their crews from the hazards of the sea.
