June 28, 1941 - The keel is laid for U.S.S. Wahoo (SS-238) on the newly completed No. 3 Ways at the Navy Yard, Mare Island, California. On the platform, Commander A.D. Peters reports that "The keel is well and truly laid."  All photos on this page courtesy Steve Reichmuth, Tom Anderson & Jack Kocher. 
February 14, 1942 - Eight months later, U.S.S. Wahoo (SS-238) is prepared for launch. The Mare Island Navy Yard "Grapevine", a semi-monthly newspaper, describes the occasion as a "grim Valentine for Hirohito."
Final preparations
The Christening Party - Preparing to break a bottle of champagne across Wahoo's bow is Mrs. William C. Barker, wife of Captain W.C. Barker (left). Behind her is Admiral Friedell, commander of the Navy Yard. 

Seconds after her christening, Wahoo heads down the ways.

She enters the water stern first, with flags flying, a thrilling sight to the large crowd.

The christening party watches as Wahoo enters the channel.

She slides past the end of the pier.

Coasting into the channel, the tug tug stands by as the boat floats free of the launch cradle.

The tug nudges her back towards the pier. Another four months of fitting out
will take place before she is commissioned on June 15, 1942.
