Another great LIFE archive find are these color shots from Electric Boat in Groton, Connecticut during the 1940s. Electric boat is the premier submarine manufacturer in the U.S., possibly in the world. My grandfather worked for General Dynamics (who owns Electric Boat) in sixties overseeing the construction of nuclear missile installations all over the country. Eventually, the family settled in the Groton area after he moved to the Electric Boat division. My father was stationed at the New London naval submarine base, which is how my parents met. Long story short, that is my connection to these images — not considering the work wear quality of the photos. You really have to hand it to the women of the era, they stepped up in a major way. This first shot below — the woman with the Acetylene torch —is a really powerful image.
