The cockpit is analogous in principal to the “armored bathtub” that protected the Il-2’s crew, with 24 mm of all-welded titanium alloy. Redundant controls and armored gasoline strains permit the plane to maintain injury and nonetheless be able to being flown again to base, but when all else fails the pilot can resort to his Okay-36L Zvezda ejection seat.
The Su-25K has a wingspan of 47 toes and 1 inch, a wing space of 365 sq. toes and a size of fifty toes, 11 inches. Empty weight is 21,605 kilos, and most takeoff weight is 42,549.
