When did navies stop using 100-pound bombs?

There is no single date here. Official withdrawal differs from the last time stocks were carried or used, which may survive only in an operations report.

The answer resists a neat date unsupported by the right kind of record. A weapon can disappear from official service lists before isolated stocks stop being carried or used. The comparison is with asking when the Royal Navy ended Swordfish combat operations, where a standard answer may conflict with an operations report. Equipment-retirement claims should specify whether they mean policy, inventory, carriage, or documented use.
