When the Obama administration dispatched three B-2 bombers from a Missouri air base on March 19 last year to cross the ocean and reach Libya, it put roughly $9 billion worth of America’s most prized military assets into the air. The bat-shaped black bombers, finely machined to elude radar and equipped with bombs weighing a ton apiece, easily demolished dozens of concrete aircraft shelters near Libya’s northern coast.
The Air Force points to that successful mission, and thousands of others against insurgents in Afghanistan conducted by older B-1 bombers, while arguing that long-distance, pinpoint expressions of U.S. military power are best carried out by strategic bombers. As a result, the Air Force says, the country needs more and newer versions of them, at the cost of tens of billions of dollars.
Its claims over the last year have impressed Secretary of Defense Leon Panetta, who called the idea “critical” to national security in February budget testimony. They also charmed Congress, which in December slipped an extra hundred million dollars into the defense budget to speed the creation of a top-secret new “Long-Range Strike Bomber.” Only that bomber—among the dozens of major new weapons systems now in development—was honored with a specific endorsement in the Pentagon’s new strategic review, released on January 5.
But the new bomber’s future is not assured. While Libyan and Afghan gunners may be no match, the new planes seem likely to encounter major turbulence at home, as a climate of financial austerity begins to afflict the Pentagon for the first time in a decade and other weapons compete to serve its military role.
Critics have expressed concerns that the Air Force will not fit the bombers into its budget; that their preliminary design is too technically ambitious; and that a key potential mission—conducting bombing raids over China—is implausible. They also have asked why new planes are needed when old ones are undergoing multi-billion-dollar upgrades.
By all accounts, the Air Force’s track record of making bombers the country can afford is dismal. The B-1 program was cancelled mid-stream by the Carter administration after its cost doubled, then revived under President Reagan. The B-2 grew so costly in the early 1990s that the Pentagon ended up buying just a fifth of the aircraft originally planned. The B-2s are actually not used much now, partly because few targets justify risking aircraft that cost $3 billion apiece in today’s dollars, and partly because their flights by some estimates cost $135,000 per hour—almost double that of any other military airplane.
The Air Force says the new bombers are slated to cost roughly $55 billion, or about $550 million a plane—less than a quarter of the price of the B-2. If costs rise, “we don’t get a program,” Air Force chief of staff Gen. Norton Schwartz recently told reporters, citing a 2009 warning by then-Secretary of Defense Robert Gates, an airpower skeptic, as Gates cancelled an earlier attempt to build a new bomber.
One of the skeptics is Tom Christie, the Pentagon’s chief weapons tester from 2001 until his retirement in 2005. He says that if $550 million per plane is the target, “you’re talking $2 billion by the time they build the damn thing … How many times [have] we been through this with bombers? And look where we end up.”
“Besides, what do we need it for?” adds Christie, a sardonic scientist who, in his three decades working for the military, contributed to the design of many of today’s most successful warplanes. A jowly man with snow-white hair, Christie has devoted his retirement to highlighting and criticizing what he sees as wasteful Pentagon practices.
The new bomber program has been accelerated at a particularly risky moment, when its design—by the accounts of several top officials—remains up for grabs. The Air Force has said, for example, that it may or may not be given a nuclear mission at some point in the future, a feature that would add to its price tag. The Air Force has also said it is to be “optionally manned,” meaning it conceivably could be flown from a ground station, without a pilot in the cockpit. Nothing similar, involving unmanned, armed aircraft that must survive in a hostile environment, has yet been attempted.
That kind of technological ambition has doomed many weapons program—a reality the Air Force says it recognizes. In 2009, for example, the Obama administration ordered cancellation of an advanced fighter called the F-22 after its costs ballooned and it began to suffer technological and maintenance problems.
Besides Gates, no critic has been more vocal and posed more of an obstacle to the Air Force’s bomber efforts than Marine Corps Gen. James Cartwright, a former fighter pilot who served as the vice chairman of the Joint Chiefs of Staff from 2007 until retiring in August 2011. The charismatic Cartwright was instrumental in persuading Gates to kill off the Air Force’s earlier effort to develop a new bomber. It wasn’t until Cartwright’s influence waned that the Air Force succeeded in advancing its revived bomber scheme through the Pentagon bureaucracy and Congress.
Cartwright says the nation does need several hundred new “trucks” or inexpensive bomb haulers, without fancy sensors, capable of penetrating advanced air defenses to drop guided bombs. Such weapons can cost around $20,000 apiece, or about a fifth what modern cruise missiles cost.
But Cartwright says he doubts that the Air Force can develop an effective bomber cheap enough to be bought in adequate numbers. He predicts cost increases will result in the Air Force again buying fewer than two dozen new bombers—around a quarter of what the service says it needs. Cartwright adds that he is not sure why the Air Force feels a new bomber is needed now and, equally importantly, why the service believes it can afford it. “Those are the right questions,” Cartwright says.
A record of cost overruns and shifting timetables
The Air Force’s bomber troubles stretch a long way back. The last bomber to be developed and purchased without huge cost overruns was the B-52, which began development in the late 1940s. Twice in subsequent decades, the Air Force has launched a new bomber program in order to replace the now-classic B-52, only to see costs rise and production terminated early. Seventy years after its design was conceived, the B-52 remains America’s most numerous strategic bomber.
The Air Force now says it wants between 80 and 100 Long-Range Strike Bombers, the number planners say is required to carry out a sustained bombing campaign against a well-armed foe such as China or Iran. It has said repeatedly that the new planes, which it claims will use "off-the-shelf" technologies, will be ready for flying in the mid-2020s—when America’s list of friends and foes might be different.
Between now and then, the Air Force intends to hide the plane’s design, missions, operating costs, and basing plans in an enveloping shroud of secrecy, much as it did with the B-2. “There’s a competition. The program is underway. The requirements, the cost parameters have been set by the secretary of defense and we’re executing in that direction,” Air Force Secretary Michael Donley said at a conference in February. “That’s about all we’re saying.” Northrop, Boeing, and Lockheed Martin all said they would compete for the contract, but likewise declined comment about it.
The program’s current timetable represents a shift. A decade ago, the Air Force believed it could wait until 2037 for a new bomber. But in 2001, a Defense Department strategy review warned that another world power could launch a surprise attack on a U.S. ally that U.S. ground and naval forces could not prevent—an obvious reference to a sudden amphibious assault by China on Taiwan. It called for a robust capability to strike and maneuver “within denied areas.”
“What is this but a new stealth bomber?” says David Deptula, a retired Air Force lieutenant general and former deputy chief of staff for intelligence who helped plan bomber operations over Afghanistan and the Pacific and now teaches at the Air Force Academy in Colorado and is CEO of defense and aerospace contractor Mav6.
In 2006, under then-Secretary of Defense Donald Rumsfeld, the Pentagon blessed the Air Force’s plan to produce a new bomber by 2018—and began channeling money into design efforts. The new plane was supposed to include cutting-edge sensors, communications and weapons, potentially including the world’s first operational air-to-air laser cannon—all of which added to its pricetag.
But after Gates replaced Rumsfeld in late 2006 and Cartwright joined the Joint Chiefs of Staff the following year, Gates canceled the new bomber initiative, citing the same out-of-control technological ambitions that caused the B-2 to cost $3 billion per plane. “It makes little sense to pursue a future bomber … in a way that repeats this history,” Gates said.
“Gates was listening to Cartwright at this point in time,” says Barry Watts, a bookish former Air Force and Northrop Grumman program evaluator now working for the Washington, D.C.-based Center for Strategic and Budgetary Assessments.
To lower the cost, Gates proposed the Air Force return to the drawing board and look at an unmanned design, echoing Cartwright’s own preference. A strictly pilotless bomber could dispense with the cockpit, ejection seats, and onboard oxygen systems, thereby reducing cost, Cartwright claims. “Today’s weapons and platform technologies allow an aircraft to stay airborne far longer than a human can maintain peak mental and physical performance.”
The White House Office of Management and Budget, which vets all federal spending, endorsed Gates’s decision at the time. “Current aircraft will be able to meet the threats expected in the foreseeable future,” OMB said of the bomber fleet in 2009.
“The OMB statement was actually something of an anomaly,” counters Deptula, a former fighter pilot and air power champion. “OMB has no military competence and should not be attributed any.”
Paul Meyer, a Northrop Grumman vice president, says the extra funding was not a surprise when it was officially appropriated last fall.
Last spring, the House Armed Services Committee promised to give the Air Force $100 million more than the $197 million it requested for new bomber work for the 2012 fiscal year. The committee is chaired by Rep. Buck McKeon (R-Cal.), whose district includes a secretive Air Force research and testing facility in Palmdale, outside Los Angeles, where the B-1s and B-2s were built and where the new bomber will most likely be assembled, regardless of which company wins the contract.
“I’m proud of how both the Air Force and my committee are approaching the [bomber] development,” McKeon said in a May 5 speech at the Heritage Foundation in Washington, D.C.
McKeon’s staff did not respond to multiple requests for interviews. But his plan attracted bipartisan House support: George Behan, a staffer for Rep. Norm Dicks, D-Wash., the House Armed Services Committee’s ranking member and a longstanding supporter of Boeing—a potential bomber contractor—says the unrequested, extra funding “was needed to keep it on schedule.”
In May last year, Ashton Carter, the deputy secretary of defense, met with executives from Northrop Grumman, Boeing, and Lockheed Martin to discuss the bomber and its technologies in Palmdale. “His intent was to understand what was resident in various contractors’ capabilities,” a source at the meeting said of Carter. Details of the meeting have not been disclosed, but when Panetta left as head of the CIA to replace Gates and Carter became the deputy defense secretary, both embraced the bomber enthusiastically.
“Rebalancing our global posture and presence to emphasize the Asia-Pacific and Middle East areas … requires an Air Force that is able to penetrate sophisticated enemy defenses and strike over long distances,” Panetta said in a February press briefing. “So we will be funding the next-generation bomber.”
At the same time, Panetta required that senior Defense Department officials jointly oversee its development. He also opted to defer efforts to certify it for carrying nuclear weapons—a task that requires special communications and costly hardening against radiation effects and other consequences of nearby nuclear explosions.
That decision reverses the development course of the B-1 and B-2, which were designed to be nuclear-capable from the outset and then re-engineered to carry largely nonnuclear weaponry. That change cost around $4.5 billion for the B-1 fleet alone, in 2001. The Air Force has declined to say what the cost will be of “certifying” the planes later as nuclear-capable.
A cockpit without a pilot
While meant to be at least as stealthy as the B-2, the new bomber is not meant to fly mostly alone into battle, using its own sensors to spot targets and its own electronic defenses to defeat enemy radar. It “won’t be a Swiss Army knife” like the B-2, explains Air Force spokesman Lt. Col. Tadd Sholtis, “Instead, it will rely on its integration with other systems”—such as satellites, spy drones and radar-jamming planes.
But one challenging requirement has already crept into the design: It is supposed to be flown as a pilotless drone with only minor tweaks. “It could be manned; it could be unmanned,” Meyer says. On some missions, in short, it might look like a ghost-plane, flying perfectly with no crewmembers in the installed seats.
The Air Force is no stranger to drones—even large ones. The Northrop Grumman-built Global Hawk, with a wingspan greater than the ubiquitous Boeing 737 passenger jet, which can stay aloft for 35 hours. Even the Air Force’s standard Predator and Reaper, each around the size of a Cessna, routinely fly for 14 hours or more over Afghanistan.
But the Global Hawk is unarmed, and the propeller-driven Predators and Reapers are loud, slow, and intended only for patrols in undefended airspace. The Air Force has never fielded a large, high-performance, armed drone warplane—much less one that can switch between manned and unmanned modes with minimal changes.
From the mid-1990s until 2006, the Pentagon started to develop such a drone under a contract with Boeing and Northrop Grumman. Flying prototypes, known as the X-47 and X-45, were built under the $1-billion effort, called the Joint Unmanned Combat Air Systems initiative. But the program has not produced a combat-ready copy.
Cartwright and Gates said they favored a purely drone bomber—a sort of pilotless B-52 priced to buy in large numbers. But the Air Force, with a senior leadership dominated by traditional pilots, pushed back; it insisted that a drone would not save money.
“By the time you look at a payload of 40,000 pounds, onboard fuel and the airframe itself, adding a crew and cockpit module aren’t that big a deal,” Rebecca Grant, a consultant to major aerospace firms, told Aviation Week, a trade magazine. “We want the value of a manned crew compartment”—principally, a diminished need to ensure good communications back to a control center.” Even highly autonomous drones such as the Global Hawk require a steady satellite link to operators on the ground, which enemies might try to degrade.
In January, the Pentagon canceled one variant of the Global Hawk, admitting that the spy drone was actually more expensive to operate than the 60-year old, manned U-2 it was meant to replace. “Cost savings have not materialized,” the Defense Department reported. A pilotless bomber could incur the same unexpected expense.
The Air Force also refuses to accept the notion of a pilotless bomber with a possible nuclear mission. “Could you be comfortable with a nuclear-laden RPA [Remotely Piloted Aircraft]? I wouldn’t,” Air Force chief of staff Schwartz said in a recent speech. Drone advocate Cartwright wanted to change that policy. “I don’t remember the last time I manned an ICBM,” he told a group of Washington, D.C., defense reporters last July.
But with Cartwright out of the picture, the Air Force is not about to shift positions. That means that the new bomber will retain all the risks incumbent in drone design, without the benefit of the potential cost savings that attracted Gates and Cartwright.
A mission to bomb China?
In late 2011, Capt. James Perkins, a U.S. Army infantry commander in the eastern province of Paktika, saw bombs dropping from an unseen B-1 through thick cloud cover and striking Taliban fighters with precision. “It was pretty amazing,” he said But that type of mission—against an undefended foe—is not what the Air Force has in mind for the new bomber.
Deptula explains that since 2004, the United States has been stationing B-52s at its air base in Guam, just outside the range of most Chinese weapons. In November of that year, he organized tests to see if the planes could find and sink a Chinese invasion fleet steaming towards Taiwan. Two B-52s flew from Louisiana to the Pacific and hunted for the decommissioned U.S. Navy landing ship Schenectady, which had been deliberately abandoned off the Hawaiian coast.
Spotting the Schenectady with their sensors, the bombers dropped four tons of explosives on the 522-foot vessel, pulverizing it.
The continuing presence of B-52s and B-2s on the tarmac in Guam deters China, according to Bob Elder, a retired Air Force lieutenant general who commanded the 8th Air Force—the main bomber unit. “When we want them to be seen—when we’re trying to send a signal—they’re capable of doing that,” Elder says of bombers.
This signal is less and less credible, Air Force officials say, because China hasn’t been standing still. Their military budget tripled between 2000 and 2010, and the military acquired new jet fighters, radars, and long-range HQ-10 surface-to-air missiles, representing what Schwartz calls “one of the world’s best air defense environments.” And the Obama administration—which announced a “strategic pivot” towards Asia in recent months—has expressed concern that a failure to provide a U.S. military riposte might loosen America’s political ties to its closest allies in the region.
Lately Iran, too, has been investing in air defenses that could challenge U.S. forces, Schwartz added. Technologies meant to keep out U.S. military planes “are proliferating very rapidly,” Jamie Morin, an Air Force assistant secretary and comptroller, told the nonprofit Stimson Center in Washington, D.C., this month. “The technology is widely available and comparatively inexpensive.”
Against the best defenses, the Air Force can use only the radar-evading B-2s, and only half of these are ready for combat on short notice, analysts say. The non-stealthy B-1s and B-52s are too vulnerable, and fighters including the F-22 lack the range to hit Chinese targets from secure U.S. bases.
But some experts have said that using any American plane to conduct bombing raids over China is a remote possibility, given that Beijing has a stockpile of missiles tipped with nuclear warheads that can reach major cities in the United States. The idea is both unnecessary and dangerous, said Wayne Hughes, a retired Navy captain now teaching at the Naval Postgraduate School in Monterey, Calif.
“We should not adopt an air-sea strike plan against the [Chinese] mainland, because that is a sure way to start World War IV,” Hughes told an informal gathering of naval strategists in Washington in February 2011. “We need only enough access to threaten a war at sea that destroys Chinese trade and curtails energy imports.” That more limited deterrent capability does not necessarily require a new stealth bomber, he said, because inexpensive ships and planes firing guided missiles could pose enough threat to Chinese trade to prevent any conflict.
If Hughes is correct, bomber upgrades already in the works could render the new bomber redundant. The B-52, B-1 and B-2 are all being fitted with a new cruise missile with some of the same stealth qualities as the B-2, and which can hit targets up to 600 miles away. For the cost of the new bomber fleet, the Air Force could buy 50,000 of these missiles. It has fired just 2,000 cruise missiles since it began using the long-range weapons in combat in 1991.
All three existing bombers are also getting new sensors, new radios, and structural enhancements. The Air Force has acknowledged the B-1 and B-52 will be structurally sound for at least another 29 years—and the B-2 potentially for another 50 or more. The bill for the B-2 upgrades alone is projected to be $2 billion. Even the B-52 has vast potential, Boeing officials say. “Every aspect of the aircraft—structurally, the capability to hold weapons and avionics, the power—has large margins in it,” explains Scot Oathout, Boeing’s B-52 program manager.
Air Force spokesman Sholtis responds that “continued modernization of existing aircraft at the expense of any larger leap in technology comes with serious risk. To the extent that we may be required to put our existing, upgraded forces up against more fundamentally advanced air-to-air or surface-to-air threats, we’re looking at more airmen potentially dying and more battlefield targets not being hit.”
But Christie, a veteran observer of the military services’ budgetary stratagems, speculates that other factors are at play besides military need. “You have the new [Asia-centered] strategy which, on the surface, would seem indicate some rationale for something like this [bomber],” Christie says. But he says it’s really an effort to “take advantage of things and jump in there while we can.”
Christie says the service might be acting now to prop up its budget and thus protect itself from financial ruin in the early 2020s, when two other major Air Force programs—a new tanker and the stealthy Joint Strike Fighter—will also begin full-rate production, potentially under a flat or falling overall defense budget.
By starting a major program now—any major program—the service may keep its spending high enough to fend off Pentagon planners seeking funds for the Army, Navy, and Marine Corps “You strike while the iron is hot and look at where you are five to 10 years from now,” Christie says. Officials think that “hopefully nirvana will come and we’ll have double the budgets we had. We’ll have a new war which will cause budgets to increase or we’ll have allies on [Capitol] Hill to cause them to take money away from the other services.”
