Thanks to Mark Braunlich, grandson of Frank C. Johnston, for submitting the photo scans to The Subchaser Archives. Among the boat builders awarded contracts to build 110' submarine chasers was Matthews Boat, in Ohio. Frank C. Johnston and his brother Ben worked at Matthews Boat on the submarine chaser construction project before entering military service. Ben served in France; Frank in a motor pool garage in Kentucky. These photos show the construction of chasers at Matthews Boat.
