Detailed information is scarce. Although short ranged (hight by WWII standards) it had the highest explosive power of any torpedo and its hydrogen peroxide motor left very little bubble trail.

Basically a circle running mode is what they received sometime after the war. While its not known how many torpedoes were fitted with this, its safe to assume it was a substantial amount (or all) as the USN stopped development of a unguided pattern running torpedo in favor of equipping the Mk 16 with the feature. This could work out really well for setting up shots on surface contacts that are running scared from the Mk 37.
