The Hamilton-class cutters were one of the first naval vessels built with a combined diesel and gas turbine propulsion plant. “The twin screws can use 7,000 diesel shaft horsepower to make 17 knots, and a total of 36,000 gas turbine shaft horsepower to make 28 knots. The diesel engines are Fairbanks-Morse and are larger versions of a 1968 diesel locomotive design. Her Pratt-Whitney marine gas turbine engines are similar to those installed in Boeing 707 passenger jet aircraft.”
