The Rudderow (DE-224) class was originally to comprise 72 modified Buckley class destroyer escorts which would be completed to a new specification. Fifty of these were completed as high speed transports (APD) instead leaving only 23 DE's built to the DE-224 specification. A further 179 units were cancelled in Sep-Oct 1943.
DE-224 and 225 were completed with Babcock & Wilcox boilers. DE 230, 231, 684-686, and 706-709 were fitted with Combustion Engineering boilers and DE-579 thru 589 had Foster Wheeler boilers. Endurance was 15,000 miles at 15 knots with 378 tons oil. This class replaced the three 3-inch guns of the Buckley class with two 5-inch/38 dual purpose guns in a single turret forward and aft and placed an additional twin 40mm mounting forward. The bridge and funnel were reduced in height.
Fifty units of this class were completed as fast transports (APD.87-136 and 139) and one (APD.137) was converted to this role in 1945 while the conversion of two further units (APD.138-139) was cancelled. As APDs, they could carry 162 troops.
In 1945 some units had their torpedo tubes removed to make way for a further six 40mm AA or a tripod mast stepped for carrying anti-submarine radio direction finding equipment for duty as radar pickets.
These ships were decommissioned and placed in reserve following World War II with few exceptions. Many APDs were recommissioned for service in the Korean War; these were again decommissioned in the late 1950s. By the mid 1970s most had been scrapped. Twenty five were foreign military sales.
