Hypersonic weapons could give the B-1 bomber a new lease on life
By: Aaron Mehta
NATIONAL HARBOR, Md. — It's been a rough stretch for the U.S. Air Force's fleet of 62 B-1B Lancer bombers, with a pair of fleet shutdowns over safety concerns and the confirmation of plans to start retiring the plane as the new B-21 comes online, even as the much older B-52 remains in service.
But speaking at the Air Force Association's annual conference Monday, Gen. Timothy Ray, the head of Air Force Global Strike Command, seemed to throw his support behind keeping the B-1 around for quite some time. In fact, in Ray's mind, the B-1′s capabilities might expand.
Several times throughout the speech, Ray emphasized that while the B-21 is slowly spinning up, he can't afford to lose any capability. Indeed, Ray seemed to posture toward keeping the B-1 over the long term, according to John Venable, a senior defense fellow at the Heritage Foundation and former F-16 command pilot.
“One of the major takeaways [from the speech] is that the B-1 is not going to go away nearly as soon as people thought,” Venable said, “and that's a good thing.”
Under the Air Force's stated goal of 386 squadrons, the service's force mix requirement is about 225 bombers. The service currently has 156, Ray said, and even with the B-21 coming online sometime in the 2020s, planned retirements to the B-1 and B-2 would keep the bomber force under 200.
Ray's belief in the B-1 spans from two broad assessments. First, freed from the heavy workload of B-1s performing regular close-air support activities in Iraq and Afghanistan, the fleet will experience less wear and tear, and hence survive longer than projected.
“We're just flying the airplane in a way we shouldn't have been flying it, and we did for far too long. The good news is we're resetting that entire team,” Ray said.
“What we thought was a very sizable load of structural issues” ended up being a “fraction” of issues to deal with, he added.
Those structural issues have become particularly visible in the last 16 months, with the entire B-1 fleet grounded twice for mechanical issues. In June 2018, the fleet was grounded for two weeks following the discovery of an issue with the Lancer's ejection seat; in March 2019, another ejection seat issue grounded the fleet for almost a month. Members of Congress have since expressed serious concerns about the B-1's readiness rates, a number that was just more than 50 percent in 2018.
Ray expressed optimism about the mechanical issues, saying that any fallout from the ejection seat shutdowns will be completed by the end of October, which is “must faster” than the service predicted.
The second reason Ray believes there's still life in the B-1? The idea that there are modifications to the Lancer that would add new capabilities relevant in an era of great power competition.
In August, the Air Force held a demonstration of how the B-1 could be modified to incorporate four to eight new hypersonic weapons by shifting the bulkhead forward from a bomb bay on the aircraft, increasing the size inside the plane from 180 inches to 269 inches. That change allows the loading of a Conventional Rotary Launcher, the same system used inside the B-52, onto the B-1.
According to an Air Force release, first reported by Military.com, the bulkhead change is temporary, giving the B-1 flexibility based on its mission. Overall, the internal bay could be expanded from 24 to 40 weapons, per the service. In addition, the testers proved new racks could be attached to hardpoints on the wings.
“The conversation we're having now is how we take that bomb bay [and] put four potentially eight large hypersonic weapons on there,” Ray said. “Certainly, the ability to put more JASSM-ER [Joint Air-to-Surface Standoff Missile Extended Range] or LRASM [Long Range Anti-Ship Missile] externally on the hardpoints as we open those up. So there's a lot more we can do.”
Said Venable: “I think it's a great idea. Increasing our bomber force end strength, we're not going to get there just by buying B-21[s] and retiring the B-1s.”
“Adding a new rotary [launcher that] he was talking about, just behind the bulkhead of the cockpit of the B-1, freeing up the pylons to actually manifest more longer-range weapons and give it a greater penetrating strike capability — those are great takeaways from this particular event,” the analyst added.

SpaceX and ULA win massive national security launch contracts
Nathan Strout SpaceX and United Launch Alliance have won massive five-year National Security Space Launch contracts from the U.S. Space Force and National Reconnaissance Office, the Space and Missile Systems Center announced Aug. 7. The contracts will support more than 30 heavy lift launches planned between fiscal 2022 through 2027, with task orders to be made from fiscal 2020 through 2024. 60 percent of launch services orders will go to ULA, with SpaceX taking up the remaining 40 percent. The two firm-fixed-price, indefinite delivery requirement contracts included funding for the first year of launches: $337 for ULA and $316 for SpaceX. “This is a groundbreaking day, culminating years of strategic planning and effort by the Department of the Air Force, NRO and our launch service industry partners,” said William Roper, assistant secretary of the U.S. Air Force for Acquisition, Technology and Logistics, in a statement. “Maintaining a competitive launch market, servicing both government and commercial customers, is how we encourage continued innovation on assured access to space. Today's awards mark a new epoch of space launch that will finally transition the Department off Russian RD-180 engines.” Following a Congressional mandate, the Department of Defense began the NSSL competition in 2019 to end U.S. reliance on the Russian propulsion systems used for the Atlas V and Delta IV rockets. A four-way competition ensued, with Blue Origin, Northrop Grumman and ULA designing new rockets for the military and SpaceX submitting their already certified Falcon 9 and Falcon Heavy rockets. The Space and Missile Systems Center claimed that a report issued in April by think tank RAND supported its decision to award contracts to only two launch providers, arguing that the market could only support two. “This landmark award begins the dawn of a new decade in U.S. launch innovation, while promoting competition, maintaining a healthy industrial base, and reinforcing our global competitive advantage,” stated Lt. Gen. John Thompson, commander of SMC and program executive officer for space. “This acquisition will maintain our unprecedented mission success record, transition National Security Space payloads to new launch vehicles, assure access for current and future space architectures and cultivate innovative mission assurance practices.” With the announcement, SMC announced the first three missions to be assigned under the new contracts: USSF-51 and USSF-106 for ULA, and USSF-67 for SpaceX. All three will take place in fiscal 2022. https://www.c4isrnet.com/battlefield-tech/space/2020/08/07/spacex-and-ula-win-massive-national-security-launch-contracts/
