Groton — A 400-foot barge built to help deliver Columbia-class ballistic missile submarines arrived Monday at Electric Boat, the prime contractor for the submarines.

The new Ocean Transport Barge Holland, constructed by Bollinger Shipyards of Lockport, La., was named after John Holland, the Irish-born immigrant who designed the first submarine purchased by the Navy. The original Holland was built at EB and delivered in 1900.

“We are happy to welcome Holland to her new home in the Groton shipyard,” EB President Kevin Graney said. “Our fellow shipbuilders at Bollinger have delivered a terrific asset, on time and on budget. Holland will play an important role in the construction of the Columbia class of submarines, which will carry nearly 70% of the nation’s nuclear arsenal.”

The Columbia class is being built at EB’s Quonset Point, R.I., manufacturing facility. Skilled tradespeople will construct and outfit Columbia modules at Quonset Point, and the modules will then be transported by the Holland barge to the company’s final test and assembly facility in Groton. The first Columbia module is expected to arrive in Groton in 2023.
