I worked for EB (General Dynamics Electric Boat Division) back in 1976. I worked on the actual Ohio that the Ohio class is named for, and the Los Angeles that the Los Angeles class (also known as the 688 class) is named for.
I have friends who are retired from there and others that still work there. It's an impressive facility. Yeah... Between Sikorski, Pratt and Whitney, and EB, you could say Connecticut is kind of big in the war business.
