Citat:Engines
This section requires expansion with: describe original engine(s) used. (February 2013)
For a study for the U.S. Air Force in the mid-1970s, Boeing investigated replacing the engines, changing to a new wing, and other improvements to upgrade B-52G/H aircraft as an alternative to the B-1A, then in development.Boeing later suggested re-engining the B-52H fleet with the Rolls-Royce RB211 535E-4. This would involve replacing the eight Pratt & Whitney TF33s (total thrust 8 × 17,000 lb) with four RB211s (total thrust 4 × 37,400 lb)—which would increase range and reduce fuel consumption, at a cost of approximately US$2.56 billion for the whole fleet (71 aircraft at $36 million each). A Government Accountability Office study concluded that Boeing's estimated savings of US$4.7 billion would not be realized and that it would cost US$1.3 billion over keeping the existing engines, citing significant up-front procurement and re-tooling expenditure, as well as the RB211's higher maintenance cost. The GAO report was subsequently disputed in a Defense Sciences Board report in 2003; the Air Force was urged to re-engine the aircraft without delay. Further, the DSB report stated the program would have significant savings, reduce greenhouse gas emissions, and increase aircraft range and endurance, in line with the conclusions of a separate Congress-funded study conducted in 2003. In 2014, the U.S. Air Force was reviewing industry studies of engine replacement.[108] The re-engining has not been approved as of 2014.
Citat:Starting in 2016, Boeing is to upgrade the internal rotatory launchers to the MIL-STD-1760 interface to enable the internal carriage of smart bombs, which can currently only be carried on the wings.
Naredne godine bice 60 godina operativne upotrebe ,sluzice on jos najmanje pola od ovog sto je proslo ako ne i vise .
