In addestramento sul Mare di Barents ...

Quote

The latest Bomber Task Force (BTF) mission in Europe occurred Thursday over the Barents Sea as a U.S. Air Force B-52 Stratofortress bomber aircraft conducted integration operations with NATO Allies.
The bomber, assigned to Minot Air Force Base’s 5th Bomb Wing in North Dakota, departed Thursday and flew to designated locations where the bomber integrated with Greek and Norwegian F-16 Fighting Falcon aircraft and conducted aerial refueling operations with U.S. and Turkish KC-135 Stratotanker aircraft. 
Upon completion of the missions, the aircraft and crew immediately returned to North Dakota. 
Missions like this demonstrate America’s continual global strike and global reach capabilities through the employment of strategic bombers.
The mission originally involved two bomber aircraft, but one aircraft safely diverted to RAF Fairford, England, Thursday afternoon due to a maintenance issue.

Scopo della missione?
La deterrenza ...

Quote

Two B-52s flew directly to the Persian Gulf from Barksdale Air Force Base, La., in what the military says is a message of deterrence to Iran.
The bombers, from the 2nd Bomb Wing, took off from their home base Dec. 9 and integrated with other U.S. Air Force and partner nation aircraft during the long-range mission, according to a U.S. Central Command release (*)
The tasking came on a short notice, with the goal of proving the U.S. can send bombers anywhere, anytime.

Un avvertimento all'Iran ...

Quote

The United States flew strategic bombers over the Persian Gulf on Wednesday for the second time this month, a show of force meant to deter Iran from attacking American or allied targets in the Middle East.
One senior U.S. military officer said the flight by two Air Force B-52 bombers was in response to signals that Iran may be planning attacks against U.S. allied targets in neighboring Iraq or elsewhere in the region in the coming days, even as President-elect Joe Biden prepares to take office. 
The officer was not authorized to publicly discuss internal assessments based on sensitive intelligence and spoke on condition of anonymity.

Ritorno a Guam ...

Quote

Four U.S. Air Force B-52H Stratofortress bombers returned to the Indo-Pacific region Jan. 28 for a Bomber Task Force deployment, conducting operations out of Andersen Air Force Base, Guam.
The bombers, from the 96th Bomb Squadron at Barksdale AFB, La., deployed in support of Pacific Air Forces’ training efforts with allies, partners and joint forces. 
These strategic deterrence missions reinforce the rules-based international order in the Indo-Pacific region.
“Deploying as a Bomber Task Force exercises our ability to produce agile, combat power in any location we are needed,” said Lt. Col. Christopher Duff, 96th Bomb Squadron commander. 
“Our strategic bomber missions demonstrate our always-ready global strike capability. We remain ready to deploy to reach anywhere in the world at any time.”

... It is still “too early to say ...

Quote

This summer, the U.S. Air Force expects to have all the data it needs from the three defense companies competing to replace the B-52 bomber’s engines, but it is still “too early to say” when a contract will be awarded, a top general said Feb. 25.
The service is waiting for the three competitors - General Electric, Rolls-Royce, and Pratt & Whitney - to provide more information about proposals each company submitted last year, according to Gen. Timothy Ray, who leads Air Force Global Strike Command.
“The request for proposals is out,” he told reporters during a roundtable hosted during the Air Force Association’s virtual Aerospace Warfare Symposium. 
“We should have this summer the answers back from the competitors to be considered. And so then, from that process, we’ll go from there.”

Sono anni che stanno discutendo dell'eventuale ri-motorizzazione dei B-52H ... nel frattempo i costi ...

Quote

The total program cost of re-engining the B-52H fleet of 76 airplanes will be about $11 billion, a 9 percent jump over a previous estimate because of more up-to-date data, Acting Air Force Secretary John P. Roth told lawmakers June 17.
Roth told the Senate Armed Services Committee that recent press reports of a 50 percent increase are incorrect. 
This new number reflects information obtained from virtual prototyping of the system, along with “a re-assessment of the requirement” and the inherent complexity of integrating a modern, commercial engine onto the “aging platform that the B-52 is,” he said.
The cost increase also takes into account the “realities of buying from the current industrial base,” Roth said.
The Air Force was not immediately able to provide precise numbers, or whether the 9 percent is a base year or then-year cost.

Rimotorizzazione ... sarà la volta buona?

Quote

A contract award for new engines for the venerable B-52 bomber is “imminent” and could occur as early as this month, the U.S. Air Force’s top acquisition officials said Tuesday.
The service is set to decide whether General Electric, Rolls-Royce or Pratt & Whitney will produce modified commercial engines to outfit the B-52, which is set to fly through at least 2050.
“We’re starting to wrap that work up. It shouldn’t be much longer,” said Lt. Gen. Duke Richardson, the Air Force’s top uniformed officer for acquisition.

Oltre alla rimotorizzazione ... vi sarà qualcosa d'altro ...

Quote

Boeing will integrate the selected engine onto the B-52, converting the jet’s old analog engine controls to digital ones. 
While Boeing provided “information” to the Air Force about which engines were relatively easier or harder to integrate - and what other changes might be required - the company did not make a recommendation of any particular engine, a Boeing program official said. 
Boeing will decide how the engines should be placed on the wings and whether to mount them in twin-engine nacelles, as the TF33s are mounted now. 
The official said the disused infrared blisters on the aircraft’s nose will be removed to improve airflow to the new engines, restoring the aircraft’s original profile.  
In addition to the B-52’s engines, the Air Force is planning to replace the bomber’s radar, communications systems, and much of the cockpit

Rimotorizzazione ... ha vinto Rolls-Royce ...

Quote

The Air Force has selected Rolls-Royce North America as its contractor for the B-52 Commercial Engine Replacement Program, or CERP, which will supply new F130 powerplants for all 76 of Air Force Global Strike Command’s B-52H bombers, the Pentagon announced Sep. 24. 
If all options are exercised, the work is worth $2.6 billion.
The F130 engine is flying on the C-37 transport and E-11 BACN (Battlefield Airborne Communications Node) aircraft. 
The first part of the indefinite quantity-indefinite delivery contract is worth $500.9 million. 
The contract calls for Rolls to supply 608 engines, to equip 76 B-52s with eight engines each, with manufacture and installation to be completed by Sept. 23, 2038. 
Rolls said the actual number of powerplants, including spares, is 650.
The Air Force did not say when the installs will begin. 
The engines will be built at Rolls’s Indianapolis, Ind., facilities, where the company said it has invested $600 million in an “advanced manufacturing campus.” 
The work will require 150 new hires, the company said. 
The contract value is substantially below initial estimates, which ran as much as $10 billion for the CERP.

I nuovi motori per il B-52H ... parla Rolls-Royce ...

Quote

To win the B-52 Commercial Engine Replacement Program, Rolls-Royce digitally “built” the bomber’s wing with the company’s F130 engines installed to demonstrate its advantages, Rolls-Royce North America President and CEO Tom Bell said in an online seminar.
“We digitally integrated that engine into the pod, into the pylon, into the wing, and dynamically modeled the entire system of operation to model for the customer exactly how efficient that product would be on that wing,” which was “designed … in the 1950s, early 60s,” Bell said in a streaming discussion with Defense One. 
He also revealed that Rolls’ proposal calls for modifying the wing “as little as possible” in order to reduce risk.
With the digital model, “We were able to demonstrate for the Air Force … how our engine, and this approach, would lower their integration risk, so as to integrate this engine efficiently, affordably, and on schedule,” Bell said. 
The digital model also demonstrated how maintenance could be accomplished more easily, he said.
