Blenny & Cochino 552k Looks like the start of another work day as E.B. employees climb up the stairwell past the "No Swimming at this site" sign near the new North Yard. An officer on deck of the soon to be launched Blenny (SS-324) looks across the opposite ways at the construction of a prefabricated section of the Cochino (SS-345).
The pace of construction progresses quickly as a worker tightens the bolts on part of her hull. The Cochino's keel would officially be laid 13 April. Construction of the boat will be moved over to the soon to be vacated way that the Blenny now occupies.
By early 1944, most of the building yards were forced to adopt some measure of pre-fabrication in order to expedite the building process. Manitowoc was the acknowledged master of this art and it allowed them to complete boats quickly in a limited amount of building space (Manitowoc built their boats to EB plans). While EB did not go to the same extent as Manitowoc, even they pre-fabricated some sections and attached them to the keel once it was laid.
The date of the photo is probably around the first week of April 1944. The Blenny would be launched on the 9th.
Note the Blenny's open outer torpedo door shutters still need to be affixed.

In Memorium:
In the Second Book of Shmuel (Samuel), 22nd chapter, 5th through the 20th verses, translated from the original in Hebrew and published by the Koren Publishers of Jerusalem, Israel, 1982, can perhaps aptly describe the fate of the crew and all other U.S. submariners who died defending their county:

"When the waves of death compassed me / the floods of ungodly men made me afraid; / the bonds of She'ol encircled me; / the snares of death took me by surprise; / in my distress I called upon the Lord, / and cried to my G-D: / and he heard my voice out of his temple, / and my cry entered into his ears. / Then the earth shook and trembled; /the foundations of heaven moved / and shook because of his anger /...the heavy mass of waters, and thick clouds of the skies /... And the channels of the sea appeared, / the foundations of the world were laid bare, / at the rebuking of the Lord, at the blast at the breath of his nostrils. / He sent from above, he took me; / he drew me out of many waters; / he delivered me from my strong enemy, and from those who hated me; for they were too strong for me. / They surprised me in the day of my calamity: / but the Lord was my stay / He brought me forth also into a large place: / he delivered me because he delighted in me./"
