Файл:USS Helena (CL-50) at the Mare Island Naval Shipyard on 27 June 1942 (19-N-31213).jpg

English: View of the starboard side amidships of the U.S. Navy light cruiser USS Helena (CL-50), taken at the Mare Island Naval Shipyard, California (USA), 27 June 1942, following repair of combat damage and an overhaul.
Note the ship's redesigned forward superstructure, including an open bridge and reduced lower bridge wings. The Mark 34 main battery gun director, with antenna for an FC gunfire control radar, is immediately in front of the foremast. The other director, just behind the open bridge, is a Mark 33, with antenna for an FD radar mounted on its front. The weight traversing gear on the main deck, between the forward superstructure and 6/47 gun turret # 3, indicates that Helena is undergoing an inclining experiment to determine her stability.
