As built, armament consisted of a single 4.5 inch Mark 8 naval gun forward, and a four-round launcher for the Sea Cat surface-to-air missile aft, backed up by two 20mm cannon. A hangar and flight deck for a single light helicopter, intended to be the new Westland Lynx (although "Amazon" was first equipped with a Westland Wasp as the Lynx had not yet entered service). A Type 992Q surface/air search and target indication radar was fitted, together with a Type 978 navigation radar. Two Type 912 fire control radars (the Italian Selenia RTX-10X) directed the ship's gun and the Seacat, while a Type 184M medium range search sonar and a Type 162M bottom search sonar (modernised versions of the sonars used on the "Leander"-class) were fitted.
