Was your Dad in the Asiatic Fleet at the beginning of the PTO of WW2. Not a lot of 4-pipers saw combat action, but several in the Asiatic Fleet did.
North Atlantic for most of the war then transitioned to Pacific and hit by Kamikazi in 1945. First German sub sunk off the coast of USA was in April 13-14 1942 off of NC was done by the Roper DD-147.

http://www.uboatarchive.net/U-85.htmThe story my dad told was a little different than this wiki page in that they did try to pickup survivors but they believed another sub was in the area and they continued to depth charge a contact and in the process killed all the survivors in the water.
http://en.wikipedia.org/wiki/German_submarine_U-85_%281941%29This sort confirms my dad's version of this story.
Former commander of German U-boat U-802 and author Helmut Schmoeckel suggested in a 2002 book that the failure of Roper to rescue the U-85 crew after they abandoned the submarine and Roper '​s subsequent depth charging of U-85 should be investigated.
Notable events involving Roper include:
23 Mar 1942
USS Roper sank the bow section of the damaged American tanker Naeco with gunfire. The Neaco was torpedoed by German U-boat U-124 about 65 nautical miles south-east of Cape Lookout, North Carolina in position 33°59'N, 76°40'W.
31 Mar 1942
USS Roper picks up 70 survivors of the American passenger ship City of New York that was torpedoed and sunk on 29 March 1943 by German U-boat U-160 40 nautical miles east of Cape Hatteras in position 35°16'N, 74°25'W.
14 Apr 1942
On this day USS Roper (Lt.Cdr. Hamilton Howe) sank U-85 near Cape Hatteras, USA.
U-85 was the first U-boat to be sunk off the North American coast after the start of the Operation Drumbeat (Paukenschlag) on 13 January 1942.
On the day that she was sunk U-85 stayed on the surface through the engagement. After repeated gunfire hits on the boat, fatally damaging her, the order to abandon ship was given and maybe half of the crew got into the water and then U-85 started to sink again fast. USS Roper then dropped 11 depth charges onto the already sinking U-boat and its 2 dozen survivors and in the process killed everyone in the water.
The wreck of U-85 is now a popular dive site.
23 Apr 1942
USS Roper picks up 30 survivors from the Panamanian merchant Desert Light that was torpedoed and sunk on 16 April 1942 east of Cape Hattaras in position 35°35'N, 72°48'W by German U-boat U-572.
29 Apr 1942
USS Roper picks up 14 survivors from the British merchant Empire Drum that was torpedoed and sunk on 24 April 1942 southeast of New York by German U-boat U-136. 13 more survivors from the same ship were picked up on 1 May.
Arriving at Norfolk on 21 December, Roper sailed again on 29 January 1945. On transiting the Panama Canal, she reported to the Pacific Fleet, and, after stops in California and Hawaii, moved into the Mariana Islands. On 11 May, she departed Guam for the Ryukyu Islands. Arriving in Nakagusuku Wan on 22 May, she circled to the Hagushi anchorage the same day. Three days later, while on screening station off that transport area she was hit by a kamikaze.
