Were Bitterns really flak sloops?

The four-inch battery could fight aircraft and small craft, but the sloop's escort mission was broader than a dedicated anti-aircraft label suggests.

Question

Is describing HMS Bittern as a flak sloop accurate?

Short answer

Only partly: her guns provided air defense, but they also fought small craft while depth charges supported a broader convoy-escort role.

Notes

High-angle four-inch guns made air defense important, but the same weapons could engage small surface craft. Their higher rate of fire also made them effective against E-boats, a use associated here with Tribal-class destroyers. Depth charges covered submarines. A sloop was not expected to duel major warships; its practical escort job was to protect a convoy against aircraft, U-boats, and fast small attackers.
