HMS Attacker (D02) was an American-built escort carrier that served with the Royal Navy during the Second World War.
Converted from a merchantman under construction, she was commissioned by the United States Navy on 30 September 1942, as USS Barnes (CVE-7), a Bogue-class escort carrier; she was decommissioned and transferred to the Royal Navy on the same day under the Lend-Lease agreement.
Attacker served throughout the war, first as a convoy escort in the Battle of the Atlantic. After further conversion by the Royal Navy in October 1943, into an assault carrier, the ship was active in the Mediterranean, and later the war in the Pacific. In late August 1945, Attacker witnessed the Japanese surrender of Penang, in Malaya, as part of Operation Jurist.
