The unique design of the BARRACUDA Class makes this boat readily distinguishable from other US submarines, particularly in reference to its bulbous bow profile (see photos below). A larger conning tower and protected bridge were enhancements that continued in subsequent class designs. Innovations regarding the placement of additional buoyancy tanks, partial double hull construction and non-circular cross sectioning were included. Further improvements to hatch design and placement plus propulsion modifications along with the B class' three periscopes were held in high regard throughout the submarine community. However, the US Navy's quest for a reliable fleet boat was not to be found in the Barracudas.

Heavy in the forward section due to the hull design and its bow configuration, this resulted in extremely difficult handling. Unreliable engines and bow planes which retracted into the outer hull made adjustments difficult and only added to their operational woes. 

Their contribution to the war effort was a major disappointment. The USS Barracuda conducted six war patrols but was unsuccessful in making so much as a single enemy contact. Realizing that these boats were basically unfit for combat duty, they were relegated to supply and training duties until decommissioning and scrapping.
