May 28 (Reuters) - Union members at General Dynamics' ( GD )

Electric Boat submarine-making unit have voted to ratify

a new contract, the United Auto Workers said on Wednesday.

The union, representing over 2,400 marine drafters at

Electric Boat, said 85% voted in favor of the ratification of

the new five-year agreement which secures a 30% wage increase

over the life of the contract and an improved wage progression.

In total, members will see a cumulative $115,000-per-member

increase in total compensation during the agreement, UAW said.

The ratification comes over a month after members authorized

a strike, demanding cost-of-living adjustments (COLA) to keep up

with inflation.

Electric Boat is a part of the defense contractor's marine

systems segment, which assembles nuclear-powered submarines for

the U.S. Navy.
