Royal Navy air defense assumed fighters, heavy anti-aircraft guns, escorts, and multiple ships would thin an attack in layers. Two cruisers caught without that formation faced experienced carrier aviators from three Japanese carriers in numbers the doctrine had not been designed to absorb. HMS Enterprise and two destroyers nevertheless entered the danger area to rescue survivors, reflecting confidence in their own air defenses and a determination to recover the crews. Bofors might begin disrupting an attack farther out, but changing the medium gun could not replace absent fighters and escorts. The missed chance for a British night carrier strike remains a major counterfactual, while intelligence and reconnaissance failures explain how the actual encounter developed. The Force Z comparison makes the wider lesson explicit: deploying a force without the carrier support assumed by its doctrine was an operational decision, not a defect one medium gun could repair.

Isolated cruisers faced a carrier strike without layered air defense
The loss of isolated cruisers in the Indian Ocean was an operational failure that neither all-Bofors nor all-Pom-Pom armament could have corrected.
