O-12

O-12 Electrical Division, aka the "E-Div". The photo is reported to be circa 1917 but the O-12 was not in commission yet. Being commissioned on October 19, 1918. The photo is more likely to have been taken after the submarine arrival in Coco Solo, Panama soon after commissioning. The O-12 was decommissioned on June 17, 1924.

There are additional crew in the background at the left side of the photo. Note the O-12's rectangular conning tower deadlight windows, distinctive of the Lake design.

O-12 pierside for a crew photo opportunity, possibly at Coco Solo, Panama, circa 1921. There are numerous civilians on the pier, and this is probably a Navy Day celebration or some sort of holiday. The duty officer is standing aft by the fairwater chatting with a woman visitor. He is wearing a sidearm and carrying an overcoat. Both the deck gun and the torpedo loading skid are in the raised position.
