The canopy is approximately 140 inches long, 45 inches wide, 27 inches tall, and weighs approximately 360 pounds. It is a rotate/translate design, i.e. comes down, slides forward, and locks in place with pins. It is the largest one-piece canopy in production today.[2]

The canopy's transparency (by Sierracin) features the largest piece of monolithic polycarbonate material being formed today. It has no canopy bow and offers the pilot superior optics (Zone 1 quality) throughout (not just in the area near the HUD) and offers the requisite stealth features.[2] The 3/4 inch polycarbonate transparency is actually made of two 38-inch-thick (9.5 mm) sheets that are heated and fusion bonded, with the sheets melding to become a single-piece and then drape forged, i.e. not laminate as in the F-16.[2] A coating of iridium-tin oxide gives the canopy a gold color and is used to reflect radar waves away from the inside of the cockpit.[6]

Post-ejection canopy-seat-pilot collision has been designed out as the framed canopy weighs slightly more on one side than the other and slices nearly ninety degrees to the right as it clears the aircraft. The canopy is resistant to chemical/biological and environmental agents, and has been successfully tested to withstand the impact of a four-pound bird at 350 knots. It also protects the pilot from lightning strikes.[2]
