Navy Hires Boeing To Develop A Very Fast And Long-Range Strike Missile Demonstrator

The Navy will use the new high-speed demonstrator to help refine its requirements for future stand-off anti-ship and land-attack missiles.

oeing has received a contract to help develop a ramjet-powered high-speed missile demonstrator for the U.S. Navy. The company says that the design will aid the service in identifying requirements for future air-launched missiles, possibly ones able to reach hypersonic speeds, that its F/A-18E/F Super Hornets and other combat aircraft within its carrier air wings will be able to employ against targets on land or at sea.

The company's Defense, Space & Security division announced that the Naval Air Warfare Center Weapons Division (NAWCWD), part of Naval Air Systems Command (NAVAIR), had awarded it this contract, worth approximately $30 million, on Oct. 20, 2020. The work will be conducted under what is officially called the Supersonic Propulsion Enabled Advanced Ramjet (SPEAR) program. The goal is to conduct the first flight of the demonstrator in late 2022.

"We have a talented team of engineers to meet the challenging technical demands and schedule timeline that the SPEAR program requires," Steve Mercer, the Program Manager at Boeing for the SPEAR effort, said in a statement. "We look forward to working with Navy experts to advance technologies for the Navy's future capabilities."

It's not entirely clear what kind of missile demonstrator the Navy is looking for exactly for the SPEAR program. The acronym includes the word "supersonic," but Boeing's press release cites its prior work on the X-51A Waverider, an experimental air-breathing hypersonic vehicle that featured a scramjet engine. Hypersonic speed is generally defined as anything above Mach 5.

At the same time, Boeing also highlighted its work on "the Variable Flow Ducted Rocket propulsion system under the Triple Target Terminator program in 2014." The Triple Target Terminator program, or T-3, which the Defense Advanced Research Projects Agency (DARPA) led, explored concepts for very-long-range air-launched missiles that would be able to engage hostile aircraft, cruise missiles, and air defense threats on the ground, hence the name.

A Variable Flow Ducted Rocket propulsion system is a kind of rocket ramjet, a relatively well-established concept at its core, in which gas produced by burning a source of solid fuel is mixed with compressed air fed into a combustion chamber via a duct or air intake to produce thrust. Advanced designs that allow for varying the flow of gas into the combustion chamber make it possible to throttle the thrust and adjust the speed of the vehicle the ramjet is powering. With this in mind, it's worth noting that NAWCWD issued a request for information regarding "Solid Fuel Ramjet Propulsion Manufacture/Test" in March, though it is unclear if that contracting notice is related in any way to SPEAR.

In addition, Boeing's press release says that it will "co-develop" the SPEAR demonstrator, but it's unclear if this means another company is involved in the effort or that the Navy's own engineers and scientists will be directly assisting with the work. The website of the Naval Aviation Systems Consortium (NASC) lists a contract award to the company relating to the SPEAR program on Aug. 31, valued at just over $32 million, but for the demonstrator's airframe only. NASC "has been formed to support the technology needs of the Naval Air Warfare Centers (NAWCs) and the Naval Air Systems Command (NAVAIR) through the use of Other Transaction (OT) Authority," according to the site.

There is no mention of this award in the Pentagon's daily contracting announcement for Aug. 31, which is supposed to include any deal valued at more than $7 million. The SPEAR contract that Boeing has just announced also does not appear in today's notice, so it's unclear when the Navy formally awarded these two contracts and whether or not they are, in fact, the same one. The War Zone has already reached out to Boeing for more information about its involvement in the SPEAR effort.

Whatever the company's role in the project is or isn't, the press release certainly indicates that it will be a stepping stone to the development of future anti-ship and land-attack missiles that will be integrated onto aircraft in the Navy's carrier air wings. This includes the services F/A-18E/F Super Hornets, another Boeing product, a significant number of which eventually slated to go through the Block III upgrade program, which will add a host of advanced features that you can read about in more detail in this past War Zone piece. At the same time, the clear indication is that any operational weapons that follow-on from the SPEAR effort could be added to the arsenal of the service's F-35C Joint Strike Fighters, as well.

An F/A-18E Super Hornet, at left, and an F-35C Joint Strike Fighter, at right, share space on the flight deck of the Nimitz class aircraft carrier USS Abraham Lincoln during tests in 2018.

"The contract award comes after the Department of Defense requested information from the defense industry to help the Navy determine technical requirements of future carrier-based land and sea strike weapons systems," Boeing's press release said.

"The SPEAR flight demonstrator will provide the F/A-18 Super Hornet and carrier strike group with significant improvements in range and survivability against advanced threat defensive systems," Mercer, the firm's SPEAR program manager, added.

Very-long-range, high-speed strike weapons could be very valuable for the Navy's carrier air wings, especially as potential near-peer adversaries, such as China and Russia, continue to develop and field increasingly longer-range and otherwise more capable surface-to-air missile systems and associated radars and other sensors. Aircraft carriers and their associated strike groups and air wings are also increasingly at risk from various anti-access and area-denial capabilities, further underscoring the need for weapons with greater range and that are able to prosecute targets faster to help ensure their survival.

At present, the primary air-launched stand-off anti-ship and land-attack missiles available to them are the AGM-84D Harpoon anti-ship cruise missile, the AGM-84H/K Standoff Land Attack Missile-Expanded Response (SLAM-ER), and the AGM-158C Long Range Anti-Ship Missile (LRASM), all of which are subsonic.

The service is in the process of developing the AGM-88G Advanced Anti-Radiation Guided Missile-Extended Range (AARGM-ER), which will have at some surface strike capabilities and will also serve as the basis for a Stand-in Attack Weapon (SiAW) for the U.S. Air Force. However, the exact speed and range of this weapon are unclear. The Navy is also developing a powered cruise missile derivative of its AGM-154 Joint Stand-Off Weapon (JSOW) glide bomb.

Boeing's SPEAR announcement comes as the U.S. military as a whole is pursuing a wide array of new hypersonic strike weapons, including unpowered boost-glide vehicles and air-breathing missiles. The Air Force is working toward its own "Expendable Hypersonic Multi-Mission Air-Breathing Demonstrator" as part of a program called Mayhem, which is linked to work on advanced turbine-based combined cycle engines.

That service is also working closely with DARPA on the Hypersonic Air-breathing Weapon Concept (HAWC) project and its own Hypersonic Attack Cruise Missile (HACM) effort. Lockheed Martin, which is leading the development of the HAWC missile, has proposed a follow-on design for use by the Navy in the past.

In August, the Air Force had said it was looking at designs from Boeing, as well as Lockheed Martin and Raytheon, to meet a requirement for "a solid-rocket boosted, air-breathing, hypersonic conventional cruise missile, air-launched from existing fighter/bomber aircraft." It's not clear if that announcement was related to HACM or not, but the following month, Boeing released a computer-generated promotional video featuring a B-1 bomber firing what the company described as a notional hypersonic missile. The company has subsequently released a more detailed still rendering featuring this conceptual missile that, at least visually, appears to be an air-breathing design.

All told, it's hardly surprising that the Navy is also in the process of pursuing its own high-speed strike missiles to arm its carrier aircraft. There's no reason to believe that the weapons that emerge from SPEAR won't be suitable for integration onto land-based platforms, such as the service's P-8A Poseidon maritime patrol aircraft, as well.

Whatever SPEAR's final design looks like, it's an important step forward for the Navy in providing this capability to its combat aircraft fleets in the future.

    Australian defense leaders defend submarine buy with France’s Naval Group

    By: Nigel Pittaway MELBOURNE, Australia – Australian defense leaders this week denied claims that their department was urged to consider alternatives to the navy's plans of buying 12 large conventionally-powered submarines from France's Naval Group. The claims, reported by local news media in the wake of an Australian National Audit Office (ANAO) report about the program earlier this week, suggested negotiations with Naval Group were at such a poor state the Commonwealth-appointed Naval Shipbuilding Advisory Board had earlier recommended drawing up contingency plans. However, in a statement released Wednesday by Secretary of Defence Greg Moriarty, Chief of Defence Force Gen. Angus Campbell, Chief of Navy Vice Admiral Mike Noonan and Deputy Secretary Naval Shipbuilding, Tony Dalton, denied the claims. “Contrary to media interpretations of ANAO's latest report on the Future Submarine Program, Defence was not advised to ‘walk away' from Naval Group by the Naval Shipbuilding Advisory Board,” the statement read. “In line with best practice and following the advice of the Advisory Board, Defence has continued to assess all of the risks that attend this highly complex program. At each stage, we are adopting relevant risk mitigation strategies. The ANAO acknowledges that Defence has taken steps to manage risks.” The 12 Attack-class submarines are being acquired under Australia's Sea 1000 (Future Submarine) program to replace six existing Collins-class boats which, without a major service life extension program, will need to be retired by 2036. The design is based on the French Barracuda-class nuclear attack boat, and the program is valued at either $34.5 billion (50 billion Australian dollars), or $55.2 billion (AUD 80 billion), depending on accounting practices. Either way, it is Australia's largest-ever defense acquisition program. The ANAO report, titled “Transition to Design,” found that the design phase of the program is already nine months behind schedule and two important milestones had been missed. It said Defence “could not demonstrate” its expenditure of $396 million (US $273 million) on the design to date has been fully effective in achieving the two milestones to date. The Defence Department has spent 47 percent of all program expenditure thus far on design work and, despite the risk mitigation strategies, it continues to describe program risk as “high”. “While the first scheduled major milestone under the Submarine Design Contract was reached five weeks later than planned, Defence and Naval Group are working towards the recovery of this delay by the next contracted major milestone in January 2021. Importantly, the delivery of the Attack-class submarine has not been delayed,” the statement continued. “Acknowledging the scale of this program, we remain confident that our work on the Attack-class program with Naval Group and Lockheed Martin Australia (as the Combat Systems Integrator) is progressing thoroughly and will result in the delivery of a regionally-superior submarine from the early 2030s, establishing a truly sovereign capability as we maximize the involvement of Australian industry.” The Sea 1000 program timeline calls for delivery of the first Attack-class boat in 2032 with service entry around 2034. https://www.defensenews.com/2020/01/17/australian-defense-leaders-defend-submarine-buy-with-frances-naval-group

  • UK facilities for American F-35 jets are delayed and over budget

    UK facilities for American F-35 jets are delayed and over budget

    By: Valerie Insinna WASHINGTON — The U.S. Air Force is on track to begin permanently basing its F-35 jets abroad next year, with RAF Lakenheath in England set to become the service's first international F-35 base. But construction on new hangars and facilities necessary for supporting the high-tech stealth jet have gone over budget and over schedule, and many buildings won't be ready when the first planes arrive in November 2021. On average, construction projects associated with the F-35 beddown at Lakenheath are about 25 percent over the initial $480 million budget estimated in 2015, said Lt. Col. Clinton Warner, who leads the 48th Fighter Wing's F-35 program integration office. “The overall trend has been projects are late and also over budget,” he told Defense News during a July interview. “A lot of the assumptions that were made back in 2015 weren't necessarily valid. There's been cost growth that was outside of the planning assumptions that were made back in 2015.” The cost increase is not the only problem. As RAF Lakenheath's first F-35 squadron stands up, neither the hangars planned to house the jets nor the headquarters building used for planning operations and maintenance will be ready, Warner said. A training simulator building will also be late. Despite the delays, the Air Force still plans to move forward with the beddown of the jet. Warner said the service is exploring options to keep operations on track, such having the new F-35 squadron share space with existing units — which include three American F-15 squadrons — or potentially leasing additional facilities on base from the United Kingdom. “In terms of getting here and flying the aircraft, we will still do that. [There is] really no difference in terms of the capability is going to be delivered, but it'll just look different in how we do it,” Warner said. “It will be some strain on the units here at the base, as there's more crowding and with waiting for those facilities to come online.” The arrival of U.S. Air Force F-35s in Europe has been a long-awaited milestone for the service, which announced in 2015 that RAF Lakenheath would become the first international location to get the jets. Since then, F-35s temporarily deployed to the base in 2017. “Having a fighter with the capability of the F-35s one hop closer to a part of the world that's seemingly less stable certainly will have a deterrent effect,” said Frank Gorenc, a retired four-star general who commanded U.S. Air Forces in Europe from 2013 to 2016. “Being able to daily train with the partners that have F-35s will have a deterrent effect,” Gorenc told Defense News. “It will cause interoperability to soar both on the maintenance side and on the operations side. I think the benefits of having that equipment — the demonstration of having a fifth-generation [fighter jet] in theater combined with F-15Es and F-16s — I think is the right signal.” Under the current plans, F-35 pilots and maintainers will begin to arrive at RAF Lakenheath in June 2021, with the first aircraft to follow in November. The base will eventually be home to two F-35 squadrons, each with a total of 24 jets. That beddown will follow more than five years of planning and development on the part of the Air Force, which stood up a team in 2015 to get the base ready for the incoming jets. In 2018, the U.S. Air Force chose Kier-Volker Fitzpatrick, a joint venture of U.K.-based design and construction firms Kier Group and VolkerFitzpatrick, to build and renovate all installations associated with the F-35 presence at RAF Lakenheath. Construction began in July 2019, with seven of 14 new facilities — which will include new hangars, a building for flight simulation, a maintenance unit and storage facilities — currently either being built or already complete. As unforeseen costs have mounted, the base's program integration office has had to request $90 million in additional funding from Congress, as well as permission from the Pentagon to revise the scope of the projects, Warner said. But there's no overarching answer for why costs have ballooned. “Each individual project had a different set of assumptions, a different set of risk profiles, and some were correct and some are not correct,” Warner said. With only a few years between the decision to base F-35s at Lakenheath in 2015 and the original planned start of operations in 2020, the U.S. government wanted to put a construction firm under contract sooner rather than later, said Stephen King of the Defence Infrastructure Organisation, a U.K. government agency charged with overseeing the building and maintenance of military facilities. But workforce costs grew as the project was discovered to be more complex than originally anticipated. “When the workers are tendered, the prices that are coming back in are found to be different from those originally estimated, and it seems to be the price of doing business on a military establishment. There seems to be an ‘add-on' to the outside market,” King said. Because the F-35 is a stealth jet that processes large amounts of classified information, many of the installations linked with its operations must meet certain security specifications. Building those structures to both U.S. and U.K. standards while using a foreign workforce of U.K. citizens posed challenges that the U.S. Air Force did not foresee during the design process, Warner said. “Luckily most of these problems are behind us, but they did cause delays in terms of when we were programming out in the schedule and looking at what we thought it would look like,” he said. “Some of the challenges associated with building those secure facilities were not fully understood.” Air Force officials have said keeping the projects on track was always going to be a challenge. In 2016, Col. Robert Novotny, who was then the commander of the base's 48th Fighter Wing, predicted construction projects could face troubles getting funding or finding a skilled workforce to build the new facilities, and that F-35s likely wouldn't begin to arrive on base until at least 2021 or 2022. “For me, the concern I have when I look at Lakenheath is not the F-35,” he told Defense News in July 2016. “For me, the concern I have is: Are we going to be able to build enough stuff fast enough?” https://www.defensenews.com/smr/nato-air-power/2020/08/06/uk-facilities-for-american-f-35-jets-are-delayed-and-over-budget/

    Industry could wait months for COVID reimbursements from Pentagon

    By: Aaron Mehta WASHINGTON — As the defense department seeks billions in emergency funding to reimburse industry for costs incurred during the COVID-19 pandemic, the Pentagon's top acquisition official pledged not to rush that money out the door. Speaking at the annual Defense News Conference, Ellen Lord, undersecretary of defense for acquisition and sustainment, said it will likely take five to six months before any reimbursements to industry under the Coronavirus Aid, Relief, and Economic Security (CARES) act will take place as the department seeks a “very data driven approach” to that money. Section 3610 of the CARES act allows firms serving the federal government to seek reimbursement for pandemic-related expenses, but Congress hasn't passed corresponding appropriations. Defense officials have said they need roughly $10 billion, and that without added funding from Congress, the Pentagon would have to dip into modernization and readiness funds. “We believe we need that appropriation to maintain readiness because if we do not get that what we are going to find is we are not going to get the number of units delivered, we are not going to maintain warfighter readiness, we're not going to move forward in modernization,” Lord said. “We would like to take the one-time hit and then see where we go from there.” Should Congress appropriate the requested funds, the Pentagon would issue a request for proposal, with the large primes gathering data from up and down their supply chains before returning with their requests to the Pentagon. That process will likely take two to three months, Lord said. “Then we want to look at all of the proposals at once. It isn't going to be a first-in-first-out and we have to rationalize using the rules we've put in place, what would be reimbursable, and what's not,” she added. “So overall, we think five to six months, in terms of a process.” When the COVID pandemic struck in March, hundreds of defense subcontractors had to close up shop. As of now, only 30 remain shuttered, Lord said, although she acknowledged that the department is keeping a wary eye on the situation. “What we are looking for is whether or not we're maintaining warfighter readiness for our production programs, and then relative to modernization, whether we are hitting key milestones relative to development programs,” she said. “We have seen some slowdowns. We are carefully monitoring, using monthly metrics, where we are.” While the most recent round of quarterly earnings reports from public defense companies did not show a major slowdown from COVID, Lord warned that those reports “in large part don't reflect the hits that were taken by business,” warning of a “delayed response” in terms of the diseases' economic impact on the sector. “I would contend that most of the effects of COVID haven't yet been seen, because most companies gave their employees time off, they stretched out production, paid a lot of people for working 100% when perhaps they were only getting 50% of the hours in and so forth,” she said. “So I think the system has absorbed it up to this point in time. Now when we get to the point where we're having payments and incentive fees and award fees earned, and if we haven't done the deliveries, that's where you're going to see the hit.” https://www.defensenews.com/smr/defense-news-conference/2020/09/09/industry-could-wait-months-for-covid-reimbursements-from-pentagon
