Navy Perfects New Gun For Air Defense
WASHINGTON—Announcement that the navy had perfected a five inch anti-aircraft gun which, in practice, has proved far superior to the three-inch guns now in use, was made at the navy department. No battleships have yet been equipped with the new arm, but plans are under way for installing the new guns together with improved fire control on the battleship Maryland this summer, when she is docked for overhaul.
