On the ARGO the officer quarters were located just forward of the control room and past the R.T. and hydrophone rooms. The captain had a private quarter separated from the square (officer quarters) by a curtain. The other three officers each had a private bunk. The non-commissioned officers shared the space aft of the control room, while the rest of the crew would use the temporary bunks in the forward and aft torpedo rooms.
On the ARGO there were two galleys, one powered by electricity and one burning diesel fuel located within the cunning tower. Eventually, the galley located in the cunning tower was found impractical. Meals at sea were very simple, and cooking underwater was discouraged due to the generation of water vapors which would eventually create further condensation.
There is no specific information available, but it should be assumed that these boats had at least two heads, while the early ARGO class had additional facilities located in the cunning tower.
The submarine had a small reserve of fresh water.
There was a small refrigeration system located in the auxiliary equipment room, quite far from the galley, which was located in the forward torpedo room. Non-perishable food was instead stowed in a small hold situated in the forward torpedo room.
The ARGO had a crew of 4 officers, 10 non-commissioned officers and 26 leading and enlisted men. The four officers were the commanding officer, usually a T.V., his second, the chief engineer and another engineer.
The ARGO class was not equipped with the expensive Gerolami-Arata lifts, a device consisting of a sealed chamber which would float to the surface by buoyancy and could then be retrieved by a tether connected to the bottom of it and secured to a winch. There were external hook ups to connect a sunken boat to external air and water lines. Also, each boat had two floating buoys installed above each torpedo room and which could be released to the surface. Each buoy was equipped with a telephone system and devices to have them easily located.
