How B-52 Bombers Will Fly Until the 2050s

By

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.

  • Keep modernization of the Ground Based Strategic Deterrent program on track

    Keep modernization of the Ground Based Strategic Deterrent program on track

    By: Former U.S. Air Force secretaries and chiefs of staff In 1959, the U.S. Air Force deployed its first intercontinental ballistic missile at Vandenberg Air Force Base in California. A year later, the Navy deployed its first submarine-launched ballistic missile aboard the submarine George Washington. These systems, together with the Air Force's nuclear-capable bomber force, formed the United States' nuclear deterrence capability, which came to be known as the “triad.” The triad has been the foundation of U.S. national security policy for over 60 years, providing stability to America's global military operations and diplomacy efforts. The triad — and the security umbrella it extends to our allies and partners — has fostered decades of peace and prosperity. Nuclear deterrence has successfully prevented crises from escalating to conflicts and promoted cooperation and diplomacy in resolving disputes. Today, nuclear deterrence is more important than ever, which is why we must prioritize efforts to modernize the triad. Throughout the Cold War and into the 21st century, military and political leaders have worked together to maintain a credible, safe and reliable nuclear deterrence capability. As technologies and threats evolve, so has the triad. Over the years, each leg has been modernized several times. Currently, the Air Force is developing the B-21 long-range strike bomber, which will enter service later this decade, and the Navy is replacing its fleet of ballistic missile submarines with the Columbia class, scheduled to begin patrols in 2031. A replacement is also needed for the Minuteman ICBM system, which first entered service in 1962 and has been upgraded and extended 40 years beyond its original service life. In 2010, after affirming the importance of maintaining a land-based leg, the Obama administration initiated the Ground Based Strategic Deterrent program, a modern ICBM system that will improve reliability, lower operational costs, and respond to current and future threats. The Air Force will soon begin work on GBSD, which will enter service in 2029. Over 10 years of planning have led to this goal, with the program's necessity validated by two presidential administrations, six congresses and six secretaries of defense. ICBMs are an integral part of the triad, providing complementary capabilities to the sea-based and bomber legs that enhance our overall deterrence posture. For example, land-based missiles are the most robust and stabilizing leg of the triad. Consisting of 400 active, hardened missile launch facilities on sovereign U.S. soil and dispersed over 30,000 square miles, ICBMs pose a nearly insurmountable obstacle to those who wish us harm. They prevent any rational adversary from credibly threatening or confidently planning a strike. Failing to adequately maintain the land-based leg of the triad by fully funding the GBSD would threaten strategic stability and make remaining U.S. nuclear forces more vulnerable. America's ICBM force is both affordable and cost-effective — it features the lowest annual sustainment and recapitalization costs compared to the other two legs. It is vital the nation maintain its nuclear force posture, which has acted as a stabilizing element of global security for decades. Modernizing the triad is no small undertaking, and our current modernization efforts are the result of decades of careful planning and bipartisan support. Stewardship is handed down from one set of leaders to the next, and in this critical moment of transition it is imperative our current leaders keep these modernization programs on track. We strongly recommend that members of Congress support moving ahead with the GBSD program so it can join the other legs in providing effective deterrence for decades to come.

    Did your state receive the most defense dollars? We’ve got the numbers.

    By: Aaron Mehta WASHINGTON — California topped the list of states receiving defense dollars in 2019, a period in which overall Pentagon contracts and payroll spending in the 50 states and Washington, D.C., totaled $550.9 billion, the Department of Defense revealed Wednesday. Of that total, $403.9 billion (73 percent) were from contracts, with the remaining $146.9 billion (27 percent) tied up in DoD personnel salaries. Overall, defense spending represented 2.5 percent of the country's gross domestic product, according to a department statement accompanying the data. The numbers, released annually, are generally included in the case made by pro-defense lawmakers and Pentagon supporters for the benefits of a large defense budget. They come as defense spending is expected to be flat, with some progressives in Congress pushing President-elect Joe Biden to cut defense funding to support social programs instead. “The report compiled by the Office of Local Defense Community Cooperation can be a great tool to state and local officials,” Ellen Lord, undersecretary for acquisition and sustainment, said in a statement. “All of our work is aimed at supporting the National Defense Strategy and this report is key as we look to continue defense reform and modernization efforts.” The top 10 states are: California: $66.2 billion Virginia: $60.3 billion Texas: $54.8 billion Florida: $29.8 billion Maryland: $26.1 billion Connecticut: $19.7 billion Pennsylvania: $18.1 billion Washington: $17.8 billion Alabama: $16.0 billion Massachusetts: $15.8 billion California, Virginia and Texas historically rank among the top states in defense dollars. California is home to a significant aerospace presence, with all the major players in that sector bringing in large chunks of cash for their in-state work. Virginia's top firm was the major shipbuilder Huntington Ingalls Industries, but the state largely brought in funding for being the corporate home for many major defense firms — and for their lobbying efforts. And 41 percent of Texas' total comes from Lockheed Martin contracts; the company's Fort Worth facilities produce the F-35 Joint Strike Fighter, among other materiel. The top 10 overall contractors for the year were: Lockheed Martin: $45.6 billion Boeing: $25.7 billion Northrop Grumman: $19.5 billion General Dynamics: $18.6 billion Raytheon: $15.7 billion United Technologies: $10.3 billion BAE Systems: $7.3 billion Huntington Ingalls Industries: $6.7 billion Humana: $6.7 billion L3 Technologies: $4.9 billion https://www.defensenews.com/industry/2021/01/13/california-top-state-recipient-of-defense-dollars

  • If the money is there, new and improved F-15s could be coming soon to the Air Force

    If the money is there, new and improved F-15s could be coming soon to the Air Force

    By: Jeff Martin IN THE AIR OVER KENTUCKY — The U.S. Air Force could buy a new version of the F-15, known as the F-15X, as long as there is enough money in future defense budgets, Air Force Chief of Staff Gen. David Goldfein told Defense News Saturday. And regardless of whether the service does buy the new jets this year, Goldfein said the new aircraft won't be taking money from the Lockheed Martin F-35. “I'm not backing an inch off of the F-35” Goldfein said. “The F-35 buy that we're on continues to remain on track. And I'm not interested in taking a nickel out of it when it comes to buying anything else in the fighter portfolio.” The FY2020 defense budget has been the focus of speculation for months, and the Pentagon has still not released a final topline figure. Original planning had called for a $733 billion topline, which dwindled down to $700 billion after calls from President Donald Trump to slash federal spending and then ballooned up to $750 billion after the intervention of then-Defense Secretary Jim Mattis. In December 2018, Air Force Secretary Heather Wilson told Defense News that “all options are on the table," and on Saturday Goldfein acknowledged that the service had built multiple budgets as different figures were proposed. “We built the [$]730[billion] budget, and we went in and did a drill said what if we only get [$]700[billion] and what do we subtract, and what if there was a [$]750[billion] budget?” he said. Goldfein would not directly confirm that the Air Force has the money in the budget for the new planes. But he hinted strongly that the service would pull the trigger on acquiring them. The F-15X is an improved model from Boeing, teaming a new airframe with an improved radar, cockpit, electronic warfare suite and the ability to carry more missiles, bringing in upgrades that have been developed for the F-15s sold to Qatar and Saudi Arabia. Late last year, Bloomberg reported that the Air Force was planning to request $1.2 billion for 12 of the fourth-generation jets in the 2020 budget request. The report said the aircraft would go to the Air National Guard to replace the olders F-15Cs, which date to the 1980s. And that age is why the Air Force is looking at a new variant. The service currently has about 230 F-15C and D model aircraft in service. However, Goldfein acknowledged those aircraft don't have the lifespan to make it to 2030 like other current fourth-generation aircraft, such as the F-15E, the F-16 and A-10. “It [has] performed brilliantly, but the cost growth runs to a point to where you're spending too much money," Goldfein said. The Air Force's decision to buy new F-15s came as a surprise late last year, as Air Force leadership had previously pushed back on the Boeing sales pitch. As recently as September 2018, Air Force Secretary Heather Wilson said that the Air Force needed to prioritize buying fifth-generation aircraft. "We are currently 80 percent fourth-gen aircraft and 20 percent fifth-generation aircraft,” she said at the time. "In any of the fights that we have been asked to plan for, more fifth-gen aircraft make a huge difference, and we think that getting to 50-50 means not buying new fourth-gen aircraft, it means continuing to increase the fifth generation.” But, Goldfein said Saturday that the decision to possibly refresh the F-15 fleet comes down to the need for more fighters in service, regardless of generation. “They complement each other,” he said. “They each make each other better.” When asked if that meant compromising for quantity over quality, he said that would not be the case. “We've got to refresh the F-15C fleet because I can't afford to not have that capacity to do the job and the missions.” Goldfein explained. “That's what this is all about. If we're refreshing the F-15C fleet, as we're building up the F-35 fleet, this is not about any kind of a trade.” He added that Air Force needs to buy 72 fighters a year to get to the amount they need in the future — and to drive average aircraft age down from 28 years to 15 years. And while Goldfein might want all 72 to be fifth generation F-35s, budgetary concerns likely won't let that happen. “If we had the money, those would be 72 F-35s. But we've gotta look at this from a cost/business case.” he explained. “An F-15 will never be an F-35. Never. But I need capacity.” https://www.defensenews.com/newsletters/2019/01/26/if-the-money-is-there-new-and-improved-f-15s-could-be-coming-soon-to-the-air-force
