Another one I've always wanted to do, especially after reading about the early battles so much recently.
This is HELENA (CL-50) at the conclusion of a refit at Mare Island in July of 1942. HELENA is camouflaged in the standard Measure 21 all-over Navy Blue (5-N) favored by the Pacific Fleet at the time.
CL-50 shows a typical mid-war electronics fit for a USN cruiser, with Mark 4 "FD" radars on the ship's Mark 33 directors, and Mark 3 Mod.1 "FC" antennas on the Mark 34 directors. HELENA's foremast mounts an SC air search antenna and an SG surface search radar below it. Waveguide losses with the early SG installations meant that they had to be placed close to the radar plot room, hence the SG's less than advantageous position. Once these issues were solved, the radar set could be relocated to the top mast as on almost all later combatants. A Curtiss SOC Seagull of Cruiser Scouting Squadron NINE (VCS-9) is spotted on the stern catapult.
HELENA was lost in this configuration after the ship was hit by three Japanese torpedoes during the Battle of Kula Gulf, with 186 men killed in action.
