The State Bond Commission on Wednesday is expected to vote on a host of financial commitments that include $20 million for the Electric Boat submarine building facility in Groton.

EB is expected to receive $28 million total in grants-in-aid — $20 million in aid for its facility in Groton and $8 million for workforce training programs for EB and its supply chain in eastern Connecticut.

Electric Boat will use $20 million to help finance dredging to support the launches of new submarines, as well as a manufacturing superstructure being built to support new submarine construction, according to a joint statement from local state Reps. Christine Conley and Joe de la Cruz.

The Bond Commission also is expected to approve $750,000 to the Connecticut Port Authority for preliminary design for structural and utility improvements at Pier 7 at Fort Trumbull State Park in New London. The pier is used by the Coast Guard, Navy and visiting vessels.

The state Department of Education is expected to receive money to provide $594,017 to the Integrated Day Charter School in Norwich for debt repayment and building upgrades and $85,500 to C.B. Jennings Elementary School in New London for unspecified site, technology or equipment upgrades.
