Electric Boat Submarine Wharf

Owner: Electric Boat

Trevcon partnered with Skanska USA Civil Northeast via a joint venture for the largest expansion of Electric Boat’s Groton shipyard in more than 45 years.

Trevcon installed five hundred caissons to complete the 200,000 square ft (about twice the area of a Manhattan city block) South Yard assembly building. This facility will enable Electric boat to US Navy’s next class of submarines – the Columbia class next generation ballistic missile submarine.
