The Cannon class was very similar in design to the Buckley class, the primary difference being a diesel-electric power plant instead of the Buckley class's turboelectric design. The fuel-efficient diesel-electric plant greatly improved the range of the Cannon class, but at the cost of speed.
Except for the propulsion, the EDSALL class was nearly identical to the CANNON class in every respect. This fourth class of destroyer escort mounted a direct-drive diesel configuration that proved to be extremely reliable.
