See also the specs in the same article. Basically, the ships had their two twin 5"/38 cal gun turrets, one fore and one aft, removed, and replaced with a single 5"/38 cal gun in the bow. The two twin 40 mm antiaircraft turrets were also removed, along with most of the antisubmarine weapons.

The Coast Guard had prepared a design for a 316-foot (96 m) cutter that was to have been an austere 327. This design was cut down into the 255-foot (78 m) ship. To accomplish this, everything was squeezed down and automated to a degree not before achieved in a turbo-electric-driven ship.

The hull was designed with constant flare at the waterline for ice-going. The structure was longitudinally framed with heavy web frames and an ice belt of heavy plating, and it had extra transverse framing above and below the design waterline. An enormous amount of weight was saved utilizing the

Myths have long shadowed the design history of the 255-foot (78 m) class. These cutters were to have been much larger ships, and two theories persist as to why they were shortened. The first is that they were built to replace the ships supplied to

The 255-foot (78 m) class was an ice-going design. Ice operations had been assigned to the Coast Guard early in the war, and almost all new construction was either ice-going or ice-breaking.
