DoD seeks industry input on multibillion-dollar cloud collaboration solution
By: Jessie Bur
The Pentagon and General Services Administration released a request for information Oct. 25 for a new unified collaborative cloud solution that will unite the entire defense apparatus under one enterprise contract.
The Defense Enterprise Office Solution is the first capability set of three that the Department of Defense plans to use to capture its enterprise collaboration and productivity needs.
The DEOS capability set needs include a productivity suite, messaging capabilities, content management systems and collaboration tools.
“We operate pretty much in a disparate environment right now, and predominantly on-[premises] for these capabilities. So DEOS will give us an opportunity to tear down some of those barriers, posture us for increased interoperability while taking advantage of what the commercial community has to offer,” said Essye Miller, principal deputy to the DoD chief information officer, at a press roundtable.
“From a benefit perspective, for us: real-time upgrades, real-time refresh, real-time access to innovation as our industry partners make them available to us.”
The contract will be offered through GSA's IT Schedule 70, which Miller said has matured to the level that was needed to support Non-Classified Internet Protocol Router, Secret Internet Protocol Router and tactical environment needs.
“In fact, IT Schedule 70 is the vehicle GSA itself used to procure its own cloud-based email, collaboration and productivity solution,” said GSA Administrator Emily Murphy, adding that GSA is committed to working with vendors who would want to propose through the expedited Schedule 70 FASt Lane program.
“Using IT Schedule 70 to help DoD procure an enterprisewide solution for email, productivity and collaboration tools could establish a baseline for GSA to scale up this type of solution across the federal government in the future.”
In fact, according to Federal CIO Suzette Kent, the DoD solution moves the federal government forward on initiatives to use and procure scalable cloud solutions across agencies.
“When we look at where we were with the report to the president across the federal government, and the intent to leverage as many common solutions for purposes of interoperability, cybersecurity ... and the overall efficiency of how we go after those solutions and the ability to keep those current, this is a really positive collaboration, and something that we're incredibly supportive of,” said Kent.
Industry has just over two weeks to respond to the RFI, which closes Nov. 9, and the subsequent request for quotes will likely be released in early 2019, according to officials.
The DoD and General Services Administration also plan to hold industry days in early December 2018 to facilitate communication between government and industry on the best way to approach the contract.
The award for the eventual contract is planned for sometime in the third quarter of 2019, and would likely be set for approximately 10 years and $8 billion, according to Murphy, though that number could change depending on industry input.
The appropriate solution would likely have to be certified at FedRAMP Moderate, said Miller.
According to Murphy, GSA and DoD have yet to determine whether a single-award or multi-award contract will best suit the DoD's needs — a debate that proved highly contentious for the Joint Enterprise Defense Infrastructure cloud contract that opened for proposals July 26 — and the RFI asks respondents to provide pros and cons for each option.
But DoD CIO Dana Deasy said that the DEOS program is part of a Pentagon initiative to bring defense operations into a multi-cloud and multi-vendor environment.
“Our intentions are to have a cloud that can serve general purpose computing needs, as well as what I have coined a term as ‘fit-for-purpose' clouds, which could consist of internal clouds or commercial clouds that have a unique fit for purpose,” said Deasy, adding that DEOS would be one such cloud.
Because DEOS is one of three collaboration capability sets the agency is looking to fulfill, DoD could end up offering a total of three contracts in that space, according to Miller.

European Hypersonic Cruise Passenger Study Set For New Tests
By Guy Norris A team of European hypersonic researchers are preparing for wind tunnel tests of a Mach 8 concept that is designed to prove technologies for the development of future ultra-long-range, high-speed commercial vehicles and air-breathing space launch systems. Funded under Europe's Horizon 2020 research and innovation program, Stratofly (Stratospheric Flying Opportunities for High-speed Propulsion Concepts) is targeted at fostering hypersonic capabilities for a 300-seat passenger vehicle cruising above 30 km (19 mi.) to TRL (technology readiness level) 6 by 2035. The project builds on the Lapcat waverider concept developed under earlier programs by the European Space Agency/European Space Research and Technology Center. Using the 310-ft.-long Lapcat II MR2.4 version as a reference vehicle, the 30-month Stratofly effort is focused on classic hypersonic technology challenges such as propulsion integration, hot structures and thermal management. In addition, with environmental concerns at the forefront in Europe, the project also includes sustainability considerations such as fuel-burn efficiency, noise and emissions reductions, as well as operational issues such as life-cycle costs, safety and certification. Coordinated by The Polytechnic University of Turin, Italy, the project team believes that sustainable hypersonic travel is feasible through the use of liquid hydrogen fuel and new trajectories that would enable flights from Europe to Australia in 3 hr. Specific targets include 75-100% CO2 reductions per passenger kilometer and 90% reductions in nitrous oxide (NOx) compared to current long-range transport aircraft. A version of the vehicle could also be adapted into the first stage of a two-stage-to-orbit space launch system, says the group. Other members of the 10-strong consortium include the von Karman Institute for Fluid Dynamics in Belgium, which is focused on propulsion and noise; the Netherlands Aerospace Center, NLR, which is also part of the noise study; and CIRA, the Italian aerospace research center, which is conducting high-speed flow analysis. Propulsion systems and climate impact input is provided by Germany's DLR research organization, while ONERA, the French aerospace research center, is focused on emissions as well as plasma-assisted combustion in the vehicle's combined-cycle propulsion system. Sweden's FOI defense research agency is also part of the plasma combustion study. The French National Center for Scientific Research is also evaluating the vehicle's potential climate impact, particularly in areas such as the effects of water droplets from the exhaust in the upper atmosphere. Studies of the overall business plan, human factors and hypersonic traffic management are being conducted by the Hamburg University of Technology, while the Spain-based Civil Engineering Foundation of Galicia is focused on structural analysis and optimization. Like the original Lapcat design, the Stratofly MR3 waverider configuration is dominated by a large elliptical inlet and an integrated nozzle aft located between two canted tail fins. For takeoff and acceleration up to Mach 4.5, the vehicle is powered by six air turbo ramjets (ATR, also known as air turbo rockets) in two bays of three, each fed by secondary inlets in the primary intake. Above this speed, sliding ramps cover the ATR inlets as the vehicle accelerates and transitions to a dual-mode ramjet/scramjet (DMR) for the next phase of the flight. The DMR is housed in the dorsal section, nested between the ATR ramjets, and is designed to operate in ramjet mode to above Mach 5 and scramjet mode up to Mach 8. The scramjet will incorporate a plasma-assisted combustion system to maintain the stability of the flame front and prevent the potential for flameouts. Tests of the plasma system in a combustor will take place later this year at ONERA, where supersonic combustion testing also took place for Lapcat. The tests will be conducted in November-December at ONERA's ATD5 facility and will focus on inlet conditions at Mach 3.7. Also planned for later this year is a test of the full vehicle in the high-enthalpy wind tunnel at DLR's Gottingen research facility. Testing at DLR will run through September 2020 and is expected to target similar free-stream conditions as those tested on Lapcat II—around Mach 7.8. The work will assess aerothermodynamic characteristics and be used to validate the results of earlier computational fluid dynamics analysis of the MR3 design, which incorporates external and internal differences against the reference vehicle. “We elevated the canard [a retractable feature for lower-speed flight] and redesigned the vertical tails,” says Davide Ferretto, a research assistant on the Stratofly team from The Polytechnic University of Turin. “We also redesigned the leading-edge radius of the inlet for increased efficiency as it feeds both propulsion systems.” As part of the redesign, the enclosed passenger compartment, which was divided into two sections running along each side of the vehicle, has been combined into a single cabin in the lower lobe of the fuselage. https://aviationweek.com/propulsion/european-hypersonic-cruise-passenger-study-set-new-tests
