Used after the 1930s
The article says this wasn't used after the 1930s, but the IJN Shinano, an aircraft carrier (started as a battleship) had an anti-torpedo bulge, according to the Wikipedia article at
[2]. Was the Japanese navy the only navy that continued that?

After the sinking of the civilian cruise ferry
MS Estonia in the Baltic Sea in 1994 many ferries in northern Europe were retrofitted with "anti-torpedo bulges". Although the purpose of those bulges were not to protect against torpedoes, but to give enough extra buoyancy so that the ferries could stay afloat even if the car deck was flooded. Just like with the warships in the 1930's the newer ferries built after 1994 instead have more internal compartments.
