Question

Which had the greatest effect on the Battle of the Atlantic: HF/DF, hunter-killer groups, escort carriers, long-range aircraft, or mass cargo-ship production?

Short answer

Escort carriers had the greatest individual effect, with long-range aircraft and HF/DF close behind and mass production enabling the wider system.

Notes

The answer treats the escort carrier as the most consequential single tool because embarked aircraft could suppress the snoopers that reported convoy positions and then extend the hunt far beyond surface escorts. Long-range aircraft and high-frequency direction finding follow closely, while mass-produced merchant hulls also enabled rapid escort-carrier construction.
