Earlier this month, Electric Boat broke ground on the centerpiece of the company’s expansion plan in preparation for the construction of a new line of submarines. The Navy plans for Electric Boat and Newport News to continue to build two of these submarines a year, and three of them in 2023. The next block of subs will be larger, adding dozens of missile tubes and about 85 feet to each of the new Virginia Payload Module (VMI) subs. The cost will also increase, from about $2.8 billion to roughly $3.2 billion for each submarine. Right now, Congress is struggling to pass a 2020 defense budget that would substantially boost the Navy’s budget for submarines.
