Inscription. The Mark 27 "Cutie" torpedo was a modified version of the Mark 24 aerial homing torpedo, with wooden guidance rails that allowed it to be launched from standard 21 inch submarine torpedo tubes. It was intended as a defensive weapon against escort ships. In spite of its low speed and small charge, it had considerable success, scoring 33 hits out of 106 fired and sinking 24 of its targets.
