Rolls-Royce Formally Enters B-52 Re-Engining Competition

July 22, 2020 | By Brian W. Everstine

Rolls-Royce formally entered the competition to re-engine the B-52 as expected, offering its F130 engine already in use in some USAF aircraft to power the bomber.

The Air Force on May 19 issued its request for proposals for the B-52 Commercial Engine Replacement Program, with responses due on July 22 and a contract award expected in June 2021. In addition to Rolls-Royce, GE Aviation and Raytheon Technologies' Pratt & Whitney will compete for the award.

The service wants to buy 608 engines for 76 B-52s to keep the bomber flying through 2050. The bomber currently uses Pratt & Whitney TF33 engines, and the service is calling for fuel efficiency savings of about 30 percent and an increase in range of up to 40 percent.

Rolls-Royce, in a July 22 statement, said the F130 engine has “the perfect size and thrust, and features a modern, efficient, and proven design.” The engine, a variant of the BR725 commercial engine, is in use in E-11s and C-37s.

GE Aviation is offering the CF34-10 and Passport engines, touting that the company has already done re-engining for the KC-135, C-5, and U-2 programs along with providing engines for the B-1 and B-2 fleets. Pratt & Whitney is offering the PW800 engine, and the company has said it has expertise on the B-52, having provided the legacy powerplant.

    Pentagon tests first land-based cruise missile in a post-INF treaty world (WATCH)

    By: Aaron Mehta WASHINGTON — The United States has tested a new ground-based cruise missile that is capable covering 500 kilometers in range, less than three weeks after officially exiting an arms treaty that banned such systems. The test occurred 2:30 PM Pacific time Sunday at San Nicolas Island, California, according to a Pentagon announcement. The missile “exited its ground mobile launcher and accurately impacted its target after more than 500 kilometers of flight,” the release said. “Data collected and lessons learned from this test will inform the Department of Defense's development of future intermediate-range capabilities.” The United States exited the Intermediate-Range Nuclear Forces (INF) treaty Aug. 2, following through on a decision made late last year that the treaty no longer benefited American interests. The INF was a 1987 pact with the former Soviet Union that banned ground-launched nuclear and conventional ballistic and cruise missiles with ranges of 500 to 5,000 kilometers. However, the United States and NATO allies have for years declared Russia in violation of the agreement. American officials have stressed they do not plan on building a nuclear ground-based cruise missile capability, but Secretary of Defense Mark Esper has said his department will “fully pursue the development of these ground-launched conventional missiles as a prudent response to Russia's actions and as part of the joint force's broader portfolio of conventional strike options.” Imagery of the test shows the weapon was launched from a Mark 41 Vertical Launch System, the same launcher used in the Aegis Ashore missile defense system. That is notable, as Russia has often claimed the Mk41 presence in Europe as a violation of the INF treaty, with the belief that the Aegis Ashore systems in Poland and Romania could be converted to offensive systems. “The launcher used in Sunday's test is a MK 41; however, the system tested is not the same as the Aegis Ashore Missile Defense System currently operating in Romania and under construction in Poland," Lt. Col Robert Carver, a Pentagon spokesman, said. “Aegis Ashore is purely defensive. It is not capable of firing a Tomahawk missile. Aegis Ashore is not configured to fire offensive weapons of any type.” The weapon itself is a variant of the Tomahawk Land Attack Cruise Missile, and was made by Raytheon, Carver said. During a recent trip to the Pacific, Esper also said he would like such weapon systems to end up in Asia as a deterrent to China. The governments in both Australia and South Korea quickly denied that any discussions about such a deployment had occurred, and Esper later downplayed his comments as a future objective. Congress will have a say in how such systems are developed or deployed. On Capitol Hill, a flashpoint in the fight is $96 million the administration requested to research and test ground-launched missiles that could travel within the agreement's prohibited range. The Democrat-controlled House passed a spending bill that would deny the funding ― and a defense authorization bill that would deny it until the administration shares an explanation of whether existing sea- and air-launched missiles could suffice. Senate Republicans are expected to fight that language during the reconciliation process. https://www.defensenews.com/pentagon/2019/08/19/pentagon-tests-first-land-based-cruise-missile-in-a-post-inf-treaty-world/

    NATO’s ‘startup’ charts a bold future in maritime unmanned systems

    By: Michael D. Brasseur , Rob Murray , and Sean Trevethan Last December, at their meeting in London, NATO leaders declared: “To stay secure, we must look to the future together. We are addressing the breadth and scale of new technologies to maintain our technological edge, while preserving our values and norms.” These two sentences were, in part, a nod to a significant piece of work the alliance is undertaking within the broader mandate of alliance innovation — NATO's Maritime Unmanned Systems Initiative. Granted, on its own this sounds both technical and narrow within the context of emerging technology, a context that includes: artificial intelligence, data, space, hypersonic weapons, bio technologies, quantum research, autonomy and more. So why are maritime unmanned systems relevant now? Simply put, developing the numbers of manned submarines, aircraft and ships required to keep pace with potential adversaries is simply not economically viable (almost $3 billion per Virginia-class U.S. submarine). Not since the Cold War has NATO needed the volume of maritime forces to protect our seas and oceans from would-be foes. NATO's areas of interest are expanding. As climate change affects the Arctic, new maritime routes are being created, which Russia in particular is exploiting with its submarines and ships. This matters because it exposes a new flank on NATO's high-north periphery, and if left unchecked is a potential vulnerability whilst also being a potential opportunity; this, coupled with an increasing need to protect our undersea data infrastructure means NATO's geostrategic responsibilities continue to grow. Therefore, if allies are to reinforce NATO's maritime posture, deter Russian aggression, guard against Chinese activity, and protect both critical national infrastructure and our sea lines of communication, NATO must do things differently and at the speed of relevance. NATO's Maritime Unmanned Systems Initiative was agreed by 13 defense ministers in October 2018. Since then, the initiative's success has attracted the participation of three more allies and garnered significant interest from all of NATO's maritime nations. The political agreement struck in 2018 provided the mandate for NATO to bring together disparate strands of common work ongoing within nations. NATO, acting as a network, enabled allies to become greater than the sum of their parts. The focus is threefold: utilize world-leading research to increase allied interoperability between conventional forces and unmanned drones; establish new tactics for our sailors to truly leverage these technologies; and develop secure digital communications for military drones across all domains (air, sea and land). Addressing these priorities together will enable this effort to be scaled across the alliance, at pace. To date, the speed of this effort has been breathtaking. So much so that even the United States and the United Kingdom — two allies who have invested the most in this area — are using the NATO initiative as a catalyst for their own national efforts. The last 12-plus months has seen the creation of a NATO project office, a governance body, as well as the planning and successful execution of the world's largest and most complex maritime unmanned systems exercise off the Portuguese coast in September 2019. This event brought together the very best from our navies, industry, scientific institutes and academia. The results were hugely impressive, with many “world firsts” including maritime unmanned systems augmenting conventional forces through multiple scenarios. We now have vast swaths of insight and information to start achieving those three goals of improving interoperability, enhancing our tactics and developing secure communications. The goal of improving allied interoperability is actually about enhancing standards. A topic often overlooked at the policy level but critical to the DNA of the NATO alliance. Standards drive interoperability, which in turn drives readiness, which ultimately aids deterrence. As NATO leads the development of new technologies, so too must come new standards that our industries and military can implement. Open architectures will be key, but allies and industry need to realize that we need to solve problems — not address requirements. No perfect solution will ever be delivered on the first attempt. The alliance will need to both innovate and iterate on operations in order to maintain advantage. This may be a cultural shift to some acquisition purists who are used to developing complex warships over 20-plus-year time frames. However, the challenge remains our ability to scale. With this project we have an agile global team functioning across multiple national and allied bureaucracies, each with their own culture and ways of working. Through engagement and investment, this team is yielding disproportionate results. Indeed, 2019 demonstrated what can be done with some imagination, effort and focus. But continual growth at speed will require faith by allies to maintain the course. Such is the nature of true change and innovation. There is a lot to do, and the stakes are high. Near-peer competitors are once again very real. Despite the global lockdown caused by the new coronavirus, COVID-19, the initiative continues to progress through synthetic networks and simulation, driven by passion and intent. Our economy, our data and its infrastructure still need protecting, now more than ever. This effort strives to accelerate maritime unmanned systems into NATO's arsenal to patrol the vast swaths of ocean and offset evolving threats. Success will be seen because it is being built on allied nations' shared values and norms, the same values and norms that NATO leaders recognized in London last year. Michael D. Brasseur is the director of naval armaments cooperation for the U.S. mission to NATO. He is also the first director of NATO's “startup,” the Maritime Unmanned Systems Innovation and Coordination Cell. Rob Murray is the head of innovation at NATO Headquarters. Sean Trevethan is the fleet robotics officer of the British Royal Navy, working in the future capability division at Navy Command Headquarters in Portsmouth, England. https://www.defensenews.com/opinion/commentary/2020/04/20/natos-start-up-charts-a-bold-future-in-maritime-unmanned-systems/
