The cockpit and parts of the flight-control system are protected by 1,200 lb (540 kg) of titanium aircraft armor, referred to as a "bathtub".[61][62] The armor has been tested to withstand strikes from 23 mm cannon fire and some strikes from 57 mm rounds.[57][61] It is made up of titanium plates with thicknesses from 0.5 to 1.5 inches (13 to 38 mm) determined by a study of likely trajectories and deflection angles. The armor makes up almost 6 percent of the aircraft's empty weight. Any interior surface of the tub directly exposed to the pilot is covered by a multi-layer nylon spall shield to protect against shell fragmentation.[63][64] The front windscreen and canopy are resistant to small arms fire.[65]
