The B-52's US$72,000 cost per hour of flight is more than the B-1B's US$63,000 cost per hour, but less than the B-2's US$135,000 per hour. [ 233 ] The Long Range Strike Bomber program is intended to yield a stealthy successor for the B-52 and B-1 that would begin service in the 2020s; it is intended to produce 80 to 100 aircraft.
A Boeing 747-400's main landing gear. Note the toes-up bias angle of the bogies on the wing gear, to ensure correct stowage upon retraction: 707, 720, 757, 767, 787: 10 wheels [1x2]+[2x4] A Boeing 757-200 from British Airways: 777: 14 wheels [1x2]+[2x6] A Boeing 777-200 from United Airlines.
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.

B-52 54-2666. The B-52C used on the mission of Thursday January 7, 1971, with the call sign "Hiram 16", had been built in the summer of 1956 as one of thirty-five B-52C bombers. From 1952 to 1962 a total of 744 B-52s of all models were built. By January 1971, all thirty-one remaining B-52Cs were stationed at Westover Air Force Base near ...
Four B-52H Stratofortress bombers from the 69th Bomb Squadron were flown to Nellis Air Force Base to participate in exercise Red Flag 15-3, which took place 13–31 July 2015. [9] B-52 crashed on a heavyweight takeoff after aborting at high speed due to all right side engines failing after a perceived bird strike. All crew members survived.
Space Shuttle Discovery landing after STS-116, with its drogue parachute deployed and its rudder split to act as an air brake. Aircraft braking systems include: Aircraft disc brakes in the landing gear, used to brake the wheels while touching the ground. These brakes are operated hydraulically, pneumatically or electrically.
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)
