On 2 April 1944, "Carmick" made two depth charge attacks with inconclusive results on an enemy submarine detected by sound contact. Later the same day, she successfully dodged a torpedo. On 18 April, "Carmick" cleared Boston for Plymouth, England, arriving 28 April to prepare for her role in the mighty naval force mounting the invasion of Europe. On 6 June (D-Day), she took station guarding the flanks of the leading ships off Omaha Beach, acting as antisubmarine and anti-E-boat screen. As the infantrymen began to move ashore, "Carmick" provided pin-point gunfire support, knocking out enemy strongpoints. She remained off the beachhead through 17 June, firing against enemy air attacks and guarding the great numbers of ships moving into the area to support forces ashore. On 10 June, she splashed a Heinkel bomber.
