The 40 mm Bofors has already returned

Could the two-pounder pom-pom concept return as an anti-drone weapon?

Its modern functional successor is already back: the 40 mm Bofors fitted to ships such as the Type 31 provides the relevant medium-caliber counter-drone capability.

The 40 mm Bofors is given as the existing answer to the proposed return of a two-pounder pom-pom. Type 31 supplies the ship example. Its gun fit is judged well suited to drone warfare, without a detailed ammunition or fire-control comparison in this short exchange.
