On January 11, 1944, FM-1 Wildcats and TBF-1C Avengers took off from the USS Block Island (CVE-21) to make the first aircraft rocket attack on a German submarine. While sinking the sub was unsuccessful, the anti-submarine hunter-killer task group, including the USS Corry (DD-463), eventually achieved their mission. During four anti-submarine cruises the hunter-killer task group sank two submarines.
The first on March 17, the group sank the German sub, U-801 and rescued it’s survivors.
Five months later the Block Island was sunk herself. A German sub slipped through undetected putting three torpedoes into the carrier.
