Spithead Royal ReviewFollowing a tradition dating back to the 14th century and as mobilization to war, First Lord of the Admiralty Winston Churchill assembled Britain's Grand Fleet for review by King George V in the summer of 1914. In what must then have been history's most grandiose flex of maritime muscle, hundreds of ships amassed, including: 55 Battleships, 4 Battle cruisers, 27 Cruisers, 28 Light cruisers, and 78 Destroyers. Making this event extra special was the appearance of the RNAS armada of seventeen airplanes, including 9 Shorts, 7 Farmans, 2 Royal Aircraft Factory BE's, and a Sopwith Bat Boat. Two airships also made an appearance.
