The only active operational model of the B-52 is the B-52H. It is currently stationed at three USAF bases, flown by four wings: [1] 2nd Bomb Wing (AFGSC) – Barksdale AFB, Louisiana. 11th Bomb Squadron (B-52H, Tail Code: LA, Gold Tail Stripe) 20th Bomb Squadron (B-52H, Tail Code: LA, Blue Tail Stripe)
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
