    Displaying standard war modifications: torpedo-launching racks (with only mounting pads fitted for after pair), a 40mm gun aft, a 20mm gun forward, and two free-swinging single machine guns abaft the torpedoes. Note the smoke generator aft and the pipe guard just forward of the 40mm gun that prevents it from firing into the boat; the free-swinging single guns have no such guard. The "Ski pole" antenna forward of the radome is an IFF transponder
