USS Card (CVE-11)

USS Card (CVE-11) was a Bogue-class escort carrier in service with the United States Navy during World War II and later operated commercially. She was notable for her prolific antisubmarine warfare operations in the Atlantic Ocean and for a high-profile loss years after naval service. Card earned recognition for supporting convoy protection and hunter-killer group tactics that aided Allied control of the Battle of the Atlantic.

Construction and Commissioning

Laid down as the Empire-class merchant hull at Seattle-Tacoma Shipbuilding Corporation under a Maritime Commission contract, the vessel was completed and converted into an escort carrier by New York Shipbuilding Corporation before transfer to the United States Navy. She was launched amid the wartime shipbuilding surge that also produced Essex-class aircraft carrier hulls and Liberty ship freighters, and was commissioned into USN service in 1943. The commissioning involved crew drawn from Naval Air Stations and officers who had served on CVE platforms in earlier Atlantic operations and in coordination with Commander, Escort Division staffs.

Design and Modifications

Originally based on a merchant ship hull similar to the Type C3 design, Card’s Bogue-class configuration featured a flight deck, hangar, catapult installations, and an armament suite intended for convoy escort and antisubmarine work. Her air group typically comprised Grumman TBF Avenger torpedo bombers and Grumman F4F Wildcat fighters, later supplemented by FM-2 Wildcat variants and SBD Dauntless-derived scout aircraft in carrier escort roles. Modifications over her career included enhanced radar suites such as air-search and surface-search sets, improved sonar coordination with convoy escorts like Destroyer Escorts, and augmented depth-charge and Hedgehog antisubmarine mortars adapted from lessons learned during engagements with German U-boat wolfpacks in the North Atlantic and the Mid-Atlantic Gap reduction.

Service History

Card operated as the center of several hunter-killer group task units that escorted transatlantic convoys between New York City, Bermuda, and Gibraltar as well as extended patrols into the approaches to the British Isles and the shipping lanes used by Royal Navy and Allied shippinges. Her air groups conducted search-and-destroy missions against U-boats using coordinated tactics with Destroyer screens and long-range patrols. Card’s squadrons claimed multiple submarine contacts and sinkings, working in concert with escort carriers such as USS Bogue (CVE-9) and HMS Tracker. During operations, Card coordinated with Task Group 21.11 and intersected intelligence from Naval Intelligence and Ultra-derived convoy routing. The ship supported air-sea rescue missions involving downed aircrews from RAF Coastal Command and United States Army Air Forces patrols, and her operations contributed to the eventual Allied dominance in the Battle of the Atlantic.

Sinking and Loss

After naval decommissioning in 1946 and sale into merchant service as SS Card, the vessel resumed commercial operations under various flags, linking North American ports with Panama and South America routes. On 2 May 1964, while laid up as a transport in the harbor of Haugesund/near Gulf of Guinea—an area of strategic maritime traffic—Card was attacked and sunk by operatives affiliated with the Algerian-backed Front de Libération Nationale-linked clandestine unit; the explosion controversially involved limpet mine devices and resulted in loss of the ship as a floating unit. The incident reverberated through diplomatic channels involving the United States Department of State and maritime insurance interests in Lloyd's of London, prompting debates in United Nations maritime security discussions and influencing counterterrorism assessments within NATO and regional navies.

Awards and Legacy

During her World War II service, Card earned commendations for her antisubmarine effectiveness and the crew received campaign ribbons associated with Atlantic Theatre operations. Her legacy includes influence on postwar anti-submarine warfare doctrine, carrier escort tactics adopted by navies including the Royal Canadian Navy and the Royal Navy, and study in naval historiography alongside other escort carriers like USS Bogue (CVE-9), USS Block Island (CVE-21), and HMS Audacity (D10). The sinking as SS Card is remembered in analyses of maritime terrorism and led to procedural changes in port security coordinated by organizations such as the International Maritime Organization and national coast guards. Artifacts and records related to Card are preserved in collections of the Naval History and Heritage Command and in museum exhibits addressing the broader escort carrier contribution to Allied victory.
