The Submarines HMS Seadog (foreground) and HMS Thunderbolt (background) at Holy Loch. 1942
A great period color shot of the S-class submarine HMS Seadog (P216), in the foreground moving off, Holy Loch, 1942. The Group 1 T-class submarine HMS Thunderbolt (N25) is in the background. Of note, Thunderbolt was originally HMS Thetis which sank with heavy loss of life in the Mediterranean just before the war and was subsequently salvaged. The two objects seen on her after casing are containers for human torpedo chariots. IWM TR 612
