  How B-52 Bombers Will Fly Until the 2050s

  By Kyle Mizokami The Air Force's fleet of Cold War bombers will fly longer than most people will live, allowing B-52 crews to work on planes their great-grandfathers flew. A series of upgrades to the B-52 Stratofortress bomber could keep the remaining fleet of Cold War bombers going until 2050. The planes, built during the Kennedy Administration, are expected to receive new engines, electronics, and bomb bay upgrades to keep them viable in nuclear and conventional roles. The B-52 strategic heavy bomber is a true survivor. It was designed to fly high over the Soviet Union carrying atomic bombs if necessary. But the B-52 is the do-it-all tool of strike warfare, taking on whatever mission is popular at the time. B-52s were modified to drop conventional bombs during the Vietnam War, where they proved they could fly low to penetrate enemy defenses, gained the ability to drop precision-guided bombs, and swapped their nuclear bomb loads for nuclear-tipped cruise missiles. The B-52s also can carry Harpoon anti-ship missiles, lay minefields at sea, and provide close air support to troops on the ground. B-52s have even flirted with air-to-air warfare, with their tail gunners reportedly shooting down two MiG-21 fighters over Vietnam. Of the original 102 B-52Hs built between 1961 and 1962, 76 are still flying with the Air Force's Global Strike Command and Air Force reserve. B-52s regularly fly to Europe and Asia, and in early June, two B-52s stationed on the island of Guam flew to the South China Sea in protest of Chinese territorial claims. Now the U.S. Air Force is embarking on a series of major upgrades that could give the B-52 another 30 years of service. According to National Defense, a key improvement will be re-engining the big bomber. Each B-52 still operates eight original TF-33-103 engines. Not only are those engines generations behind the state of the art, but their age, and the difficulty to source spare parts, puts their future use in jeopardy—a problem Popular Mechanics covered last year. Rolls-Royce, Pratt & Whitney, and GE Aviation have all expressed interest in the new B-52 engine, but only Pratt and Whitney has actually chosen a potential replacement: the PW815 engine used in the Gulfstream G500 passenger jet. The Air Force would like to replace the bomber's APQ-166 terrain following and mapping radars, which are essential for low-level flight. A bomb bay upgrade will allow the B-52 to carry JDAM satellite-guided bombs and Joint Air-to-Surface Standoff Missiles (JASSM) in its internal bay. Storing weapons internally reduces drag, increasing range. Alternately a B-52 could carry both internal and external stores. A single B-52 can carry eight JASSMs internally and twelve externally, for a total of 20 of the precision attack missiles.

  The new Air Force One just racked up its first cost overrun

  By: Valerie Insinna WASHINGTON — Boeing will have to pay $168 million out of pocket to cover increased costs on the VC-25B Air Force One replacement program, the company said Wednesday. Boeing attributed the overrun to “engineering inefficiencies” caused by the impact of COVID-19, but Chief Financial Officer Greg Smith said the program remains on schedule with a projected delivery of the first VC-25B in 2024. However, Boeing's quarterly report to the Security and Exchange Commission noted future risk to the program's cost and schedule as a result of the engineering challenges. “We believe these inefficiencies will result in staffing challenges, schedule inefficiencies and higher costs in the upcoming phases of the program,” the company stated in the report. It was not immediately clear how work on the VC-25B program had been disrupted. “That charge was really associated with COVID-19,” Smith told reporters in an April 29 phone call. “As we have folks working virtually — particularly on the engineering side — as well as that's gone, we certainly experienced some inefficiencies that has caused us to re-evaluate our estimates to complete those efforts. And that's essentially what you saw today in our results and the charge associated with that.” Smith added that although the program team has done a “good job” of managing the program in the face of changes caused by the novel coronavirus pandemic and is “executing very well on many fronts,” Boeing could not mitigate the added cost to the program this financial quarter. Air Force acquisition executive Will Roper said he spoke with Boeing Defense CEO Leanne Caret last night about the problem, but because the issue was “late breaking,” he referred detailed questions to the program office. On Wednesday night, the Air Force released a statement that — like Boeing — attributed the cost increase to “engineering inefficiencies.” Just two weeks ago, Roper praised the progress of the program, which used virtual tools to complete its critical design review in March and wrap up a modification readiness review in April. At the time, the program was on schedule with no disruptions due to COVID-19, he said then. The Air Force One replacement drew considerable attention in 2016 after then-President-elect Donald Trump tweeted that the program was too expensive and should be cancelled unless the cost—then projected as more than $4 billion—came down. In 2018, the Air Force awarded Boeing a $3.9 billion fixed-price contract to modify two 747s into the VC-25B configuration. " There has not been an increase to the $3.90B firm-fixed price contract with Boeing or the $5.3B VC-25B total acquisition cost," said Air Force spokeswoman Ann Stefanek. Although the total price of the program is estimated to hit $5.3 billion once ancillary costs such as new hangars and revised technical manuals are included, the fixed-price ceiling on the $3.9 billion deal ensures that Boeing will have to pay for any cost growth incurred while building the two new Air Force Ones. In February, Boeing began making structural changes to two Boeing 747s at its facility in San Antonio, Texas — paving the way for those jets to become VC-25Bs. The jets will also receive upgrades including enhanced electrical power, specialized communication systems, a medical facility, a customized executive interior and autonomous ground operations capabilities. “As planned in the baseline schedule, the next phase of modification is on course to begin in June 2020,” Stefanek said. https://www.defensenews.com/air/2020/04/29/the-new-air-force-one-just-racked-up-its-first-cost-overrun/
