    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

  • Here’s what the Space Development Agency wants from its first 10 satellites

    Here’s what the Space Development Agency wants from its first 10 satellites

    Nathan Strout The Space Development Agency is seeking proposals for its first batch of satellites, which will make up its initial transport layer — an on-orbit mesh network that will connect space-based sensors with terrestrial shooters. According to the May 1 solicitation, SDA is looking to award two contracts to build a total of 20 small satellites, which will comprise Tranche 0 of the National Security Space Architecture, a proliferated, low-Earth orbit constellation that will fulfill a multitude of military needs, including tracking hypersonic weapons; providing alternative position, navigation and timing data; delivering beyond-line-of-sight targeting; and more. Ultimately, the agency envisions a constellation made up of hundreds of interconnected satellites. Ten of those Tranche 0 satellites will form the agency's initial transport layer. The spiral development approach The agency is taking a spiral development approach to its National Security Space Architecture. Tranche 0 will be a testing and training segment that will demonstrate the integration of the architecture with other war-fighting efforts and inform future SDA developments. Tranche 0 is anticipated to be on orbit in the fourth quarter of fiscal 2022, with the SDA adding new tranches of satellites every two years, increasing the constellation's size and capabilities. Launch services will be acquired through the Orbital Services Program 4 contract or follow-on contracts. The philosophy behind the spiral approach is that the two-year cycles allow the agency to rapidly put new capabilities on orbit in response to evolving threats. Instead of waiting years for the perfect satellite system, the agency wants to push technologies that are currently ready into orbit as soon as possible, giving war fighters increased capabilities in the near term. With Tranche 0, the SDA wants to achieve periodic, regional, low-latency data connectivity. With Tranche 1, which will add 150 satellites to the constellation, the agency plans to provide persistent regional connectivity. Building a mesh network The National Security Space Architecture will be made up of several layers serving different functions. Tranche 0 will establish the transport layer, a space-based mesh network that will be able to pass data from one satellite to the next. The mesh network will operate as part of the Integrated Broadcast System, the Defense Department's standard network for transmitting tactical and strategic intelligence and targeting data. The key technology that will enable the transport layer are optical inter-satellite cross links, providing approximately 1 Gbps connections between the satellites. Each Transport Layer satellite will have four such cross links — forward, behind, right and left — which will allow them to pass data on to the nearest or next-nearest transport layer satellite operating in the same orbital plane. The satellites will also be capable of cross-plane cross links, meaning they will be able to connect to non-transport layer satellites operating above or below them. Assuming that they also have optical inter-satellite cross links, these non-transport layer satellites would then be able to pass data through the transport layer's mesh network to another satellite or even to a terrestrial shooter. For example, it could work like this: A space-based sensor collects imagery that it wants to pass to a ground-based system, but it is not within range of any ground station. No problem. The sensor would pass on that imagery to a transport layer satellite via an cross-plane optical cross link. The data would then bounce from transport layer satellite to transport layer satellite until it arrives above its destination, where it would then be downlinked to an optical ground terminal or distributed to the appropriate weapons system via the Link 16 tactical data network. In theory, this would allow shooters to receive space-based sensor data in near-real time. Since the SDA plans to continue building on the transport layer in subsequent tranches across multiple vendors, the optical inter-satellite cross links will need to be designed with interoperability in mind. The SDA also wants radio frequency cross links as a backup to the optical cross links. Tranche 0 will include 10 transport layer satellites — three of which will include Link 16 payloads. During an April industry day, SDA Director Derek Tournear said this initial, space-based mesh network will form the space network component to the Defense Department's Joint All-Domain Command and Control enterprise, or JADC2. “The transport layer, which is what the draft [request for proposals] and the industry day was talking about today, is going to be the unifying effort across the department. That is going to be what we use for low-latency [communications] to be able to pull these networks together, and that, in essence, is going to be the main unifying truss for the JADC2 and that effort moving forward. That is going to be the space network that is utilized for that,” Tournear explained. The agency has six goals for its Tranche 0 transport layer: Demonstrate low-latency data transport to the war fighter over the optical cross link mesh network. Demonstrate the ability to deliver data from an external, space-based sensor to the war fighter via the transport layer. Demonstrate a limited battle management C3 functionality. Transfer Integrated Broadcast System data across the mesh network to the war fighter. Store, relay and transmit Link 16 data over the network in near real time. Operate a common timing reference independent of GPS. According to the request for proposals, the SDA plans to award a contract Aug 10, with delivery expected by July 31, 2022. Responses to the solicitation are due June 1. https://www.c4isrnet.com/battlefield-tech/space/2020/05/05/heres-what-the-space-development-agency-wants-from-its-first-10-satellites/

    Leonardo signs contract to upgrade Italian Armed Force’s identification systems to new NATO standard

    Rome, March 5, 2020 - Leonardo has signed a contract with the Italian Defence authorities to supply and install ‘New Generation Identification Friend or Foe' (NGIFF) identification equipment, updated to the latest NATO Mode 5 Baseline 3 standard, for the Italian Armed Forces' land and naval platforms. The contract is worth approximately €75 million and will last for six years. Leonardo will supply several hundred NGIFF interrogators and cryptographic units in order to upgrade dozens of land and naval platforms across 15 different classes and types. The NGIFF systems will allow the Italian Armed Forces to maintain full interoperability with other NATO forces in joint operations as the alliance mandates the use of ‘Mode 5'-capable systems in its Minimum Military Requirements (MMR) for Air-to-Air and Surface-to-Air Identification. The Mode 5 standard confers a number of benefits in terms of identification and security. Identification Friend or Foe (IFF) technology is essential to military operations as it allows allied forces to be distinguished from potential threats. Under this contract, the equipment for Italy's land and naval platforms will provided entirely by Italian industry. Notably, Leonardo's Mode 5 NGIFF equipment uses the company's own cryptographic unit, which is the only alternative to a U.S. cryptographic system available on the market. Future contractual developments are planned which will see Leonardo equip further Italian aircraft and helicopters with the same capability, bringing them in-line with NATO standards. Leonardo is a worldwide leader in Mode 5-capable NGIFF technology. Previously, the company has been chosen by the UK Ministry of Defence to upgrade the IFF systems of over 400 air, land and naval platforms in collaboration with a partner company.
