How Army researchers are using software and analytics to maximize battlefield power

By:

ABERDEEN PROVING GROUND, Md. — As soldiers at every level become more connected and devices proliferate, the strain on the field-level power grid increases.

Staff at the Army's Research, Development and Engineering Command dove into the finer details of power management, auto tuning and analytics to drive how soldiers use power in the field.

Most of that work is focused around the tactical microgrid, basically the network of power that runs tactical operations.

Think thick cables, generators and all the power that lets the computers, radios and networks run to digest the vast amounts of information, communication and other electrical needs consumed by a modern military.

In the not-too-distant past, generator operators and technicians played a sophisticated guessing game that involved a clock, multimeter, flashlight and notepad to measure and mark which power supplies were running, at what level, and where they were on fuel.

But by adding digital capabilities and software-driven devices into the guts of what were simple analog generators and boxes full of copper wiring and switches, they have created a type of brain for what was formerly a mindless system.

That's resulted in the new Advanced Medium Mobile Power Source, the first new generator for the service in years.

The combination of that device, controllers within the system, and advanced software gives the soldier a centralized place to monitor and manipulate the different devices in the microgrid that will help the flow of power move to where its needed.

“I can tell you if you're using too many lights or computers on one of those three phase lines and if you're out of balance,” said Bradley Stanley, an RDECOM computer scientist.

By using software to make those readings, the end user can then shift the strain to other parts of the system, maximizing power output and fuel use for what can be 24-hour, days long operations.

Another software improvement in “autotuning” is helping make what can be a multi-person with expert training four-hour job into an automated procedure handled by the computer.

    SpaceX and ULA win massive national security launch contracts

    Nathan Strout SpaceX and United Launch Alliance have won massive five-year National Security Space Launch contracts from the U.S. Space Force and National Reconnaissance Office, the Space and Missile Systems Center announced Aug. 7. The contracts will support more than 30 heavy lift launches planned between fiscal 2022 through 2027, with task orders to be made from fiscal 2020 through 2024. 60 percent of launch services orders will go to ULA, with SpaceX taking up the remaining 40 percent. The two firm-fixed-price, indefinite delivery requirement contracts included funding for the first year of launches: $337 for ULA and $316 for SpaceX. “This is a groundbreaking day, culminating years of strategic planning and effort by the Department of the Air Force, NRO and our launch service industry partners,” said William Roper, assistant secretary of the U.S. Air Force for Acquisition, Technology and Logistics, in a statement. “Maintaining a competitive launch market, servicing both government and commercial customers, is how we encourage continued innovation on assured access to space. Today's awards mark a new epoch of space launch that will finally transition the Department off Russian RD-180 engines.” Following a Congressional mandate, the Department of Defense began the NSSL competition in 2019 to end U.S. reliance on the Russian propulsion systems used for the Atlas V and Delta IV rockets. A four-way competition ensued, with Blue Origin, Northrop Grumman and ULA designing new rockets for the military and SpaceX submitting their already certified Falcon 9 and Falcon Heavy rockets. The Space and Missile Systems Center claimed that a report issued in April by think tank RAND supported its decision to award contracts to only two launch providers, arguing that the market could only support two. “This landmark award begins the dawn of a new decade in U.S. launch innovation, while promoting competition, maintaining a healthy industrial base, and reinforcing our global competitive advantage,” stated Lt. Gen. John Thompson, commander of SMC and program executive officer for space. “This acquisition will maintain our unprecedented mission success record, transition National Security Space payloads to new launch vehicles, assure access for current and future space architectures and cultivate innovative mission assurance practices.” With the announcement, SMC announced the first three missions to be assigned under the new contracts: USSF-51 and USSF-106 for ULA, and USSF-67 for SpaceX. All three will take place in fiscal 2022. https://www.c4isrnet.com/battlefield-tech/space/2020/08/07/spacex-and-ula-win-massive-national-security-launch-contracts

  • How U.S. Open Skies Exit Could Undermine Arms Control

    How U.S. Open Skies Exit Could Undermine Arms Control

    Tony Osborne Jen DiMascio May 28, 2020 The decision by the U.S. government to withdraw from the Open Skies Treaty signed two decades ago is creating ripples of discontent within the U.S. and in Europe. Washington announced on May 22 that it would end its obligations to the arms control treaty in six months, saying that it was “no longer in the United States' best interest to remain a party to this Treaty when Russia does not uphold its commitments,” in a statement put out by the Defense Department. The Open Skies Treaty permits its 34 signatories to conduct observation flights over each other's territory. Aircraft with four types of sensors—-optical panoramic and framing cameras, real-time video cameras, infrared line-scanners and sideways-looking synthetic aperture radar—may make observations anywhere over a country's national territory. Treaty rules say that the flight may only be restricted for reasons of flight safety, not for reasons of national security. NATO and European nations may share U.S. concerns about inconsistent flight restrictions imposed by Moscow but see a U.S. departure from the agreement, in place since 1992, as regrettable. According to the U.S. and NATO, Russia has imposed restrictions on the treaty, in particular those flying near Kaliningrad, Russia's enclave on the Baltic Sea, and near the country's border with Georgia. The Pentagon also says Moscow blocked the overflight of a major military exercise in September 2019, “preventing the exact transparency the treaty is meant to provide.” In an op-ed in The New York Times, Tim Morrison, a senior fellow at the Hudson Institute and a former member of this administration's National Security Council, added that Russia has been using its overflights to collect “military relevant intelligence on the other parties, like the means to target critical infrastructure.” NATO Secretary General Jens Stoltenberg, during the May 22 meeting of alliance members, called on the Russian government to return to compliance as soon as possible, noting that the U.S. could reconsider its position if Russia complied. European Open Skies Treaty member states—including Belgium, the Czech Republic, Finland, France, Germany, Italy, Luxembourg, Netherlands, Spain and Sweden—said they would continue to implement the treaty, saying it has a “clear added value” for conventional arms control architecture and cooperative security. Russia rejects the claims of flight restrictions and contends that the U.S. had limited Russia's own Open Skies flights over Hawaii and the Aleutian Islands. Senior Russian officials, including Dmitry Medvedev, deputy chairman of the Russian Security Council, denounced Washington's decision. Medvedev said the U.S. had taken another step down the “path of dismantling the international security architecture that took decades to lay down.” Moscow believes Washington's decision could also affect other arms control treaties, with negotiations on the next New Strategic Arms Reduction Treaty potentially at risk. In Washington, the leaders of the House Armed Services and Foreign Affairs committees (both Democrats) have written a letter to Defense Secretary Mark Esper and Secretary of State Mike Pompeo contending that withdrawal from the treaty is illegal. They say it violates the fiscal 2020 National Defense Authorization Act, which requires Esper and Pompeo to notify Congress 120 days before the intent to withdrawal is presented. “This notification must be based on your joint conclusion that withdrawal is in the best interests of the United States and that other states parties to the treaty have been consulted. To date, this requirement has not been fulfilled,” wrote Reps. Adam Smith (Wash.), the Armed Services chairman, and Eliot Engel (N.Y.), the Foreign Affairs chairman. President Donald Trump and his administration have support from Repub-licans who lead the Senate for their decision to exit the treaty. Sen. James Inhofe (R-Okla.), who chairs the Senate Armed Services Committee, asserts that the U.S. should withdraw if Russia is not complying with the agreement. “It will be critical for the Trump administration to continue working with our allies and partners, especially those in Eastern Europe, to ensure they have access to the intelligence they need to protect their security. That includes facilitating access to high-quality imagery.” The U.S. had planned to upgrade the two Boeing OC-135 aircraft delivered to the Air Force in 1996. Late last year, the U.S. issued a request for information saying it was considering awarding two contracts—one for the purchase of two commercial aircraft and another to modify the airframe and provide logistics support. But the Pentagon did not include funding for OC-135 upgrades in its fiscal 2020 budget request. And in March, Esper told Congress he was not prepared to authorize funding for those upgrades until a path forward is clear. Several signatories to the treaty have dedicated aircraft for the mission; others share or lease platforms from other nations for the task. Germany is the latest country to dedicate an aircraft for the mission, using an Airbus A319 converted by Lufthansa Technik. https://aviationweek.com/defense-space/budget-policy-operations/how-us-open-skies-exit-could-undermine-arms-control
