USS Block Island (CVE-21)

USS Block Island (CVE-21) was a Bogue-class escort carrier commissioned by the United States Navy in March 1943 during World War II. She played a critical role in anti-submarine operations in the Atlantic, notably helping to sink German U-boats and protecting Allied convoys. On May 29, 1944, Block Island became the only American aircraft carrier sunk in the Atlantic after being torpedoed by U-549. Despite the loss, her crew's swift evacuation efforts resulted in the survival of most personnel, and her legacy continued with the commissioning of a second carrier bearing her name.
