  The US Army is building a ‘cloud in the sky’ for its aviation fleet

  By: Jen Judson WASHINGTON — The Army is building what is essentially a “cloud in the sky” for its current aviation fleet as it prepares the aircraft to fight alongside a future fleet under development, according to Brig. Gen. Thomas Todd, the program executive officer for Army aviation. The general spoke to Defense News in an interview ahead of the Association of the U.S. Army's annual conference. The current fleet won't dissolve into thin air when future helicopters are fielded, and they will be expected to fly together in operational environments across multiple domains. The Army is aiming to field a future attack reconnaissance aircraft and a future long-range assault aircraft by 2030. “We have to figure out a way to host a common server so that we can store data, process data and transport data quicker,” Todd said. “So while they work on the future vertical lift architecture, we still have to make the enduring fleet, that will fly alongside it, work and be capable.” So the Army is building an Aviation Mission Common Server, or AMCS, that is a stack of storage, data processing and transport capability “that's very much a flying cloud, if you will,” Todd said. The AMCS “will reside inside every aircraft. It has to reside in every aircraft because there has to be onboard processing and storage power,” Todd said, adding that it will be the engine that drives the associated user interface and apps as well as provide connectivity to the network overall. The user interface will be built upon the technology developed by Northrop Grumman for the Victor-model Black Hawk. The "V" model is an L-model UH-60 with a digital, modern cockpit like the "M" model, the latest Black Hawk variant, but not with an M-model price tag. Additionally, the interface in a V model can take on new capability through apps like a smartphone. The V model wrapped up its initial operational test and evaluation in September at Joint Base Lewis-McChord in Washington state, Brig. Gen. MacMcCurry, who is the Army G-3/5/7 aviation director inside the Pentagon, told Defense News in a separate interview. He reported the tests went well and the service looks forward to building out the fleet. The Army is currently assessing integrating the same user interface into Mike-model Black Hawks, according to Todd. The effort to build the server is part of a larger effort to ensure the current fleet is ready to fight in multidomain operations. The Army wants to obtain multidomain dominance by 2035. “We took a look at Army Futures Command's guidance on exactly what those combat aviation brigades would have in them and what would be enduring. For example, the Apache would be there indefinitely,” Todd said. “We also found that the requirements for data, the transport of and use of was exponential. So ultimately it's a problem that exists for the entire fleet, so we need to get after, at a minimum, making the enduring fleet compatible with future vertical lift, if not more capable.” There are several cross-cutting initiatives for the current fleet to make the aircraft more agile, interoperable, survivable and integrated in multidomain operations, Todd said, and the network will play an integral role. For example, the Army is working with the network community to replace its AN/ARC-201 radios with radios with the TSM waveform, which will improve and comply with future air-to-ground radio communications, according to Todd. There is also work being done within the position, navigation and timing community and with the Air Force to develop antennas, processors and software that hep the current fleet to survive battle, Todd added. And the service is working to improve power sources onboard aircraft. “There is a huge demand requirement coming, a demand signal for onboard systems and the power requirements of those is exponential. So given that it's not linear and it's going to grow exponentially, we have to get after alternative means,” Todd said. The same team that is in charge of the Improved Turbine Engine Program — which will replace engines in Apaches and Black Hawks and be the engine for the future attack reconnaissance aircraft — is looking at supplemental power units, upgrades to generators and upgrades to batteries to better power onboard systems that may not require the main power system anymore, Todd said. https://www.c4isrnet.com/2019/10/15/the-us-army-is-building-a-cloud-in-the-sky-for-its-aviation-fleet

  Change of plans: Seoul decides to start from scratch with helo competition

  By: Jeff Jeong SEOUL — It looked like Italy's aerospace group Leonardo was going to be an easy winner for South Korea's second batch of anti-submarine helicopters. The procurement program would seek 12 more AW-159 “Wildcat” helicopters, with no other competitors for the $840 million program. But the Defense Acquisition Program Administration, or DAPA, threw a curveball, deciding to accept a U.S. proposal for alternate option and to begin the competitive bidding process from the scratch. The plan for the maritime operational helicopter, or MOH, was originally to sign a direct commercial deal with a foreign helicopter maker, with three bidders — Leonardo, Lockheed Martin and NH Industries — showing interest. The two latter contenders failed to submit their proposals by the Oct. 31 deadline, leaving Leonardo seemingly as the only remaining bidder. According to sources from DAPA, however, the U.S. government in November sent a letter of price and availability of Lockheed Martin's MH-60R Seahawk, causing South Korea's arms procurement officials o rethink the acquisition approach. “We've decided to consider the U.S. FMS option,” DAPA spokesman Park Jung-eun told Defense News. “We're going to weigh in on both options of commercial and FMS contracts.” As dictated by acquisition regulation, two successive failed biddings mean that the agency can make a private contract with a sole bidder, but that's not mandatory. The agency is expected to issue a renewed request for proposals as early as March, according to DAPA officials. Leonardo would be a direct buy, while the Sikorsky bid would be a foreign military sale. Leonardo said in a statement that it would still pursue the South Korean naval helicopter program “in a fair and transparent manner.” A Leonardo spokesman said the AW-159 is optimized for the Korean theater of operations, pointing to an active electronically scanned array (AESA) radar for detecting North Korea's coastal weapon system and a missile firing range that is more than three times longer than Seahawk. “We do not really know about the details of the U.S. Navy's latest proposal,” a Lockheed Martin communications official said, declining to elaborate. “After an RFP is issued, we could be able to discuss with the service.” Pundits here expressed different reactions to the renewed MOH bidding process. Shin In-kyun, head of Korea Defense Network, a Seoul-based private defense think tank, said it's a better opportunity to acquire state-of-the-art naval helicopters with better performances. “The Seahawk is estimated to be more expensive by 20 to 30 percent than the Wildcat, but the former has performances about two times better than the latter,” said Shin. “The unit price of the MH-60R could be lowered through the FMS, as the U.S. and Indian Navies are also said to be procuring more than 40 MH-60Rs.” Shin Jong-woo, a senior analyst at the Korea Defense & Security Forum, said an FMS deal may not guarantee economic benefit for South Korea. “You give up offset programs should an FMS deal be made,” he said. “I'm not really sure how much the unit cost of the MH-60R could be lowered. If lowered, we may have to lose some optional functions of the helicopter.” Moreover, a possible MH-60R selection will bring more work to change the designs of warships, he added. “The Navy's existing warships, including the KDX-III Aegis destroyer, are not able to accommodate the MH-60R, so it's inevitable to change the design should the American helicopter be chosen.” The South Korean Navy currently operates eight AW-159s acquired under a 2012 deal. The helicopters fly missions aboard KDX-series destroyers and Incheon-class guided-missile frigates. The service plans to commission at least 12 more new frigates fitted with a flight deck and a hangar that can accommodate one Lynx helicopter. https://www.defensenews.com/2019/01/23/change-of-plans-seoul-decides-to-start-from-scratch-with-helo-competition
