DE-403, 405 and 406 were sent Design 24D on 3/11/44 and 3/15/44. The drawings were returned from Houston Shipyard on 3/17/44 because they were for the wrong ship class.
The USS Richard M. Rowell (DE-403) is shown in Measure 32 Design 22D on September 18, 1944. Even though the hull number is not visible, the official U.S. Navy caption for this photo identifies this as Ensign Merville G. Knackstedt being transferred back to the USS Sangemon (CVE-26) after being picked up after ditching his aircraft in the sea. Photo source: NARA 80-G-283756.
