Completing the cruisers was a controversial decision, reflecting exaggerated concern about Soviet cruiser construction, described as "chilling" by the director plans. The threat of the new "Sverdlov"-class cruisers was to be countered by the Blackburn Buccaneer strike aircraft, the "Tiger"s lacking the speed, range, armament and armour required and cruisers in number being seen as too expensive and as an outdated solution. Immediately post-war, the carrier and cruiser might have been complementary in the old cruiser role of defence of and attack on trade, but by 1954 trade protection was better provided by large carriers and by small and intermediate light fleet carriers operating the Hawker Sea Hawk and de Havilland Sea Venom fighters. For Australia by HMAS "Melbourne" with Sea Venom fighters and by the Canadian HMCS "Bonaventure" with McDonnell F2H Banshee fighters and 4X2 3-inch AA provided, as a priority for this role. "Hercules", completed for India as "Vikrant" and equipped with Sea Hawks and French Bréguet 1050 Alizé turboprop a/s strike planes, demonstrated its Sea Hawks in the classic attack-on-trade role to effect in the Indo-Pakistani War of 1971.
