  • Western Connecticut Navy League Adopts Submarine USS Connecticut (SSN 22)
    Western Connecticut Navy League Adopts Submarine USS Connecticut (SSN 22) STAMFORD, Conn, (July 12, 2016) - - The officers and crew of the nuclear pow- ered, fast attack submarine, USS Connecticut (SSN 22), were officially adopted by the Western Connecticut Council of the United States Navy League on June 10, 2016. The Connecticut, whose ship’s motto is the “Arsenal of the Nation”, is commanded by Commander Brian C. Taddiken and is comprised of approximately 20 officers with 150 enlisted crewmembers and is attached to Commander, Submarine Devel- opment Squadron 5 (COMSUBDEVRON FIVE). The adoption formalizes the Western Connecticut Council's commitment to en- hance the morale and general well-being of Connecticut’s crew and their families throughout the life of the ship. Both the ship’s leadership and the Council’s Board are looking forward to forging a strong relationship. Taddiken commented, “As we prepare for moving out of the yards and into an op- erational status, we are thrilled to have sponsorship by the Navy League’s Western Connecticut Council. This relationship will result in extending the state’s western borders all the way out to Bremerton, Washington and will greatly benefit the War- riors of the Double Deuce and their families.” Since its inception more than a century ago, the U.S. Navy League has been recog- nized for patriotism, strength of spirit and commitment to provide support for the U.S. sea services. One of the ways the Navy League provides this type of support is through the ship adoption program. Retired Captain Gerry Tighe, President of the Navy League’s Western Connecticut Council reflected, “Our organization has been very active supporting a number of initiatives in support of the sea services, including youth programs such as Stam- ford, Connecticut based “Dealey Division” of the US Naval Sea Cadet Corps.

Marshall (SSBN 654) as told by Dutch Kaiser This is an account of an event that I participated in, in 1967. This is how I remember the events that occurred; but of course, due to the time that has elapsed, some of the details may not be as accurate as I describe. My memory is not as good as it used to be, but the incident described did occur and this is how I remember it. I was a member of the Gold crew of the George C. Marshall (SSBN 654) when the Blue crew had a collision with a Russian Submarine while on patrol in 1967. The change of crews was to take place in Rota, Spain. The tender was the Canopus. We arrived before the boat and were standing on the deck of the Canopus when the Marshall arrived. We no- ticed that the boat was listing to port badly. When she was tied up along side the tender and we were allowed aboard, we found out the news that she had a collision with a Russian submarine and that the port side forward ballast tanks had been punctured from the collision. The Blue crew had surfaced using the Low Pressure blower. We were warned by the squadron commander and several admirals to keep our mouths shut about what had happened.
