HMIS Kistna (U46) was a Black Swan-class sloop which served in the Royal Indian Navy (RIN) during World War II.

With World War II underway, she was soon deployed for convoy escort duties between the UK and West Africa.

Wolfpack Schill was formed to attack the convoy, which was repelled by the escorts, including HMIS Kistna.

A mercantile vessel being escorted was sunk and another damaged by German aircraft with Hs 293 glider bombs.

HMIS Kistna was transferred to the Eastern Fleet and continued to escort convoys en route to Bombay.
