USS Grampus SS 207 seen sliding down the ways into the Thames River at Electric Boat Corp. on December 23, 1940. There appears to be mostly civilians on the deck of the submarine. We can see no Navy personnel in this photo. Prior to WW II the Navy sent a minimum of sailors to new construction billets while the vessel was still on the ways. Quite an elaborite collection of bunting on the bow.

USS Grampus SS 207 on November 1, 1941 undergoing post-overhaul shakedown trials off Portsmouth, N.H. She had gone to the yards for a brief overhaul after having returned from the Caribbean with USS Grayback SS 208, where they conducted modified war patrols. December 22, 1941 saw Grampus on her way to the Pacific to join the war.

The object in the right foreground is the top of the Jack Staff. It was a two part unit. The bottom being the fore most stanchion of the life lines and the top half having the bow light and flag hoist folded to the deck when not in use. (See photo below)(Thanks to Dave Johnston for the heads-up on this)

Note the ladder over the side. No doubt to get the photographer into the small boat and back aboard.

READ WAR DAMAGE REPORT #58

"On the night of 17 May 1942, while conducting a surface patrol off Truk during her second war patrol, Grampus was detected by a Japanese patrol vessel and forced to make a quick dive. While passing 30 foot depth, one shell, believed to have been a 3-inch or 4.7-inch common projectile, struck the starboard bulwark of the cigarette deck and detonated approximately three feet beyond its point of impact about two feet above the cigarette deck over the main engine air induction trunk. While no damage of a serious or military nature was caused, and Grampus experienced no difficulty in subsequently evading the enemy, the action has been included in this report to illustrate the shrapnel effect of medium caliber projectiles and the obvious vulnerability of submarines to such attacks. While other U.S. submarines have been more heavily damaged by gunfire attack, this experience of Grampus was chosen wince it is the only such action in which photographs of the damage were available to the Bureau.
