Originally an armament of three machine guns was planned, with two Lewis guns firing forwards and downwards through the cockpit floor as in the TF.1, and a forward firing Vickers machine gun. This was changed to a conventional battery of two synchronised Vickers guns in front of the cockpit, as on the Snipe, before the first prototype was complete. The guns were staggered, with the starboard gun mounted a few inches forward of the port one to give more room for ammunition. Four light bombs could also be carried.
