  New USAF Materials Hint At High-Altitude Role For B-21

  Steve Trimble The design of the Northrop Grumman B-21's trailing edge has led to speculation about a high-altitude role for the secretive stealth bomber, and new U.S. Air Force statements appear to confirm that analysis. As the U.S. Air Force enters a legally required environmental impact review process for basing the new bomber, service officials disclosed a few new details about the design on large poster boards displayed at public meetings since February. The posters are now available on B21EIS.com, a clearinghouse web site set up by the Air Force to share data during the year-long process to complete the final environmental impact statement. “The B-21 is not expected to use low altitude training routes,” the Air Force poster says. The B-2 was originally conceived as a high-altitude bomber, but a last-minute requirements change during the development phase forced Northrop Grumman to redesign the bomber for a low-altitude mission. As a result, the trailing edge was transformed from a simple W-shape to the sawtooth design seen today. The B-2, like the preceding B-52 and B-1B fleets, need low-altitude training routes. The renderings of the B-21 released by the Air Force so far reveal a trailing edge that resembles the original, high-altitude design for the B-2. The Air Force has never confirmed operational details about the future stealth bomber. Another comment on the Air Force's poster provides the first official description of the B-21's acoustic signature, as well as the performance of the engines. “The B-21 engine noise is expected to be quieter than the B-1B and about the same or quieter than the B-2,” the poster says. Previously, the only detail released by the Air Force about the B-21's engines is that Pratt & Whitney is named as one of seven of Northrop's suppliers. The poster data appears to confirm expectations that the B-21 would use a non-afterburning engine, like the similarly subsonic, flying wing-shaped, B-2. The supersonic B-1B is powered by afterburning engines. The Air Force has selected Ellsworth Air Force Base in South Dakora as the site for the first B-21 operational squadron, followed by Dyess AFB in Texas and Whiteman AFB, Missouri. The environmental impact review is evaluating Ellsworth and Dyess for the main operating beddown 1 location. https://aviationweek.com/defense-space/aircraft-propulsion/new-usaf-materials-hint-high-altitude-role-b-21

  UK - MOD sets out vision to diversify supply base

  The Ministry of Defence has today announced plans for modernising its estate and establishing a broader and more diverse supply base. The Defence Infrastructure Organisation's (DIO) new procurement plan outlines a programme of major projects and contacts for the next five financial years. This includes work to construct new buildings, such as housing and accommodation, the refurbishment of current facilities; as well as services such as catering, waste management and cleaning. The plan also sets out ambitions to establish a broader and more diverse supply base, including doing more business with small and medium size enterprises (SMEs). Currently, around 75% of spending on maintenance at defence sites goes directly or indirectly to SMEs, and further diversifying the supply base will help build resilience into projects and provide more opportunities for smaller companies to work on key defence projects. By listing all the major projects and contracts, the procurement plan will make it easier for existing and potential suppliers to plan ahead, by offering advice on bidding for this work and greater transparency on working with the MOD. These measures will help in particular small businesses, who don't always have the skills and prior experience of working with the MOD in such areas. Minister for Defence People and Veterans Tobias Ellwood said: The defence estate is where our brave armed forces live, work and train and so it's crucial we give them the best supplies and facilities possible. Working with industry is critical to delivering this, and our new Procurement Plan ensures the private sector has a head start in bidding for this crucial work. Opportunities outlined in the Procurement Plan include the £4billion Defence Estate Optimisation Programme, the Future Defence Infrastructure Services contracts - which will provide facilities management across the UK's military bases- and the £1.3bn Clyde Infrastructure Programme. The plan also details several prominent works that demonstrate DIO's key role in supporting defence throughout the UK. These include essential maintenance work worth £568 million to support nuclear infrastructure capability at HMNB Clyde, as well as a £58m investment in a modern submarine training facility at the base. Alongside this, there are plans for an £8m investment in Bovington Camp to support the AJAX armoured vehicles which will enter service in 2020. Jacqui Rock, DIO Commercial Director, said: As DIO we recognise that our current and future suppliers are key to our success. We have worked with industry to produce the Procurement Plan and we are committed to building a broader, more diverse supplier base. We believe in being as transparent as possible in our procurements and through this new approach we are encouraging new entrants, including small and medium sized enterprises, to consider the benefits and opportunities that working with DIO can deliver. The Procurement Plan will help achieve the goals set out in our first ever Commercial Strategy. This set out our vision for how we do business and how we will work effectively with our suppliers. The Procurement Plan also sets out how DIO can deliver social and economic benefits throughout its supply chain by working to contribute to the government's aim of recruiting 20,000 apprentices through construction procurement and promoting sustainability through its supply chain. By 2020, DIO has committed to a reduction of greenhouse gas emissions by 30%, a 30% reduction in domestic business flights, a 50% reduction in paper usage and reducing waste going to the landfill to less than 10%.

  The US Military Is Genetically Engineering New Life Forms To Detect Enemy Subs

  BY PATRICK TUCKER The Pentagon is also looking at living camouflage, self-healing paint, and a variety of other applications of engineered organisms, but the basic science remains a challenge. How do you detect submarines in an expanse as large as the ocean? The U.S. military hopes that common marine microorganisms might be genetically engineered into living tripwires to signal the passage of enemy subs, underwater vessels, or even divers. It's one of many potential military applications for so-called engineered organisms, a field that promises living camouflage that reacts to its surroundings to better avoid detection, new drugs and medicines to help deployed forces survive in harsh conditions, and more. But the research is in its very early stages, military officials said. The Naval Research Laboratory, or NRL, is supporting the research. Here's how it would work: You take an abundant sea organism, like Marinobacter, and change its genetic makeup to react to certain substances left by enemy vessels, divers, or equipment. These could be metals, fuel exhaust, human DNA, or some molecule that's not found naturally in the ocean but is associated with, say, diesel-powered submarines. The reaction could take the form of electron loss, which could be detectable to friendly sub drones.
