    CAE wins US Navy contract to train UC-12 aircrews

    CAE USA has received a contract to provide classroom and simulator training for the US Navy's UC-12 aircraft's aircrews. As part of the training programme, the company will provide initial and refresher training courses for naval pilots and flight officers. The programme will include training on the King Air 200 Pro Line 21 and non-Pro Line King Air 200 cockpits, in addition to the King Air 350 Pro Line 21 and Fusion cockpits. CAE USA president and general manager Ray Duquette said: “CAE has an unmatched ability to leverage a global network of training centres and training programmes. “The award of this contract is a great example of CAE's Defense and Civil business units working together to deliver a comprehensive training programme for the US Navy. We are particularly pleased that navy C-12 aircrews will be joining the army and airforce in training C-12 pilots at our Dothan Training Center in Alabama.” Alongside Alabama, training will also be delivered at the firm's facilities in Dallas, Texas, and Morristown, New Jersey. The UC-12 is a military version of the Beechcraft King Air multi-mission aircraft. Variants of the Beechcraft C-12 Huron are in service with the US Air Force, Army, Navy and Marine Corps. The navy uses the UC-12 to transport personnel and cargo, as well as for range clearance, medical evacuation, and humanitarian assistance. The department's UC-12B/F/M Huron is based on the King Air B200 aircraft, while its UC-12W Huron is as a modified version of the King Air 350. In May last year, CAE was awarded a contract to deliver instructor support services for providing ground-based training to the US Navy. https://www.naval-technology.com/news/cae-wins-us-navy-contract-to-train-uc-12-aircrews/

  • Recalculating: GPS, L-band and the Pentagon’s untenable position on 5G

    Recalculating: GPS, L-band and the Pentagon’s untenable position on 5G

    Daniel S. Goldin Last week, Ajit Pai, the chairman of the Federal Communication Commission, submitted the L-band Ligado spectrum proposal for approval, which, he said, will “make more efficient use of underused spectrum and promote the deployment of 5G” with “stringent conditions to prevent harmful [GPS] interference.” All five FCC commissioners voted to affirm the proposal, which was formally published in a 70-page report. L-band is a critical piece of spectrum that will help accelerate the deployment of U.S. 5G so we can compete and ultimately win against China. The Department of Defense argues that use of the L-band (as Ligado proposes) will interfere with GPS, which is essential to our military and economy. The FCC's final order concludes that the testing upon which the DoD and other opponents based their GPS interference claims was invalid. L-band opponents' interference measurement (termed 1dB C/No) is “inappropriate” and “there is no connection presented in the technical studies” that prove this measure of interference “relates to performance-based metrics” of a GPS receiver. In short, the FCC said there is no harmful GPS interference, and opponents have been using a flawed methodology and an invalid test with which the FCC “strongly disagree[s].” The FCC's recent report is not the first time the Ligado proposal was determined to cause no GPS interference. In early 2019, the National Telecommunications and Information Administration under David Redl reviewed the Ligado proposal carefully — along with the 20 government agencies that comprise the review body — and determined there is no interference. The NTIA then wrote a recommendation for approval and, before it could get to the FCC, it was blocked, eventually leading to Redl's dismissal. Further, over 5,000 hours of testing, including 1,500 hours at a high-tech U.S./DoD-sponsored and designed facility (performed by the world-recognized standard-in-testing National Institute of Standards and Technology scientists and engineers), proved no harmful GPS interference. Afterward, a DoD expert who monitored and confirmed the testing results told me “there is no interference problem, only a bureaucracy problem.” Yet DoD has continued to blitz the executive and legislative branches, galvanizing opposition with a compelling plea: Ligado hurts GPS, which endangers military operations and will harm the economy. Powerful. But factually wrong. And if wrong, why is Defense Secretary Mark Esper continuing to lobby against the FCC? The FCC is an independent agency. The Communications Act of 1934 charged the FCC with regulating communications for important reasons, including “for the purpose of national defense.” So why is the DoD employing principles of war — offensive operations to mass upon and seize the objective — toward the demise of Ligado's proposal and, perhaps implicitly, Ligado itself? Members of the Senate Armed Services Committee and the House Armed Services Committee are weighing in on the DoD's behalf. They have been presented partial, one-sided information. Mr. Esper is a capable, reform-minded defense secretary who has brought much-needed change to the Pentagon. But he has also been advancing one-sided recommendations from his senior staff for GPS issues, some with longstanding connections to the highly influential Position, Navigation, and Timing Advisory Board — which enjoys a level of influence akin to a special interest group within the U.S. government. A reading of the defense secretary's November 2019 letter to the NTIA reveals that even the DoD was never really sure about its own GPS interference claims, stating merely there are “too many unknowns,” the “risks are far too great,” testing shows “potential for” disruption and the Ligado system “could have a significant negative impact.” Yet, once the Ligado proposal was presented for approval on April 15 — with no new testing or analysis since November — DoD leadership tweeted that Ligado's signal “would needlessly imperil” DoD capabilities that use GPS, and risk “crippling our GPS networks.” If taken at face value, this means the DoD has spent over $50 billion over 45 years on a military GPS system that is so fragile it can be rendered useless by a 10-watt transmitter (a refrigerator light bulb) operating 23 MHz away. If true, this would represent one of the most egregious mismanagements of taxpayer dollars in federal procurement history. The pandemic has shown that China is coercing nations in need of medical assistance to adopt Chinese 5G infrastructure. Coercion from Chinese dominance in 5G would be worse. Agencies like the FCC and NTIA are in the national security arena now. As Attorney General William Barr stated in February, “we have to move decisively to auction the C-band and bring resolution on the L-band. Our economic future is at stake. We have to bear in mind in making these spectrum decisions that, given the narrow window we face, the risk of losing the 5G struggle with China should vastly outweigh all other considerations.” It is time for bold, forward-looking leadership and a wartime mindset. Chairman Pai deserves credit for setting this example. His courageous decision, coupled with support from the FCC commissioners and the strong statements of support from Secretary of State Mike Pompeo and Barr, signals a new determination to win the 5G race. L-band spectrum will enable other key elements of the U.S. 5G strategy and private sector innovation faster than any other option. It also demonstrates that a science-based approach to technology and policy is critical, otherwise we will grind to a near halt on every major decision — like this one — to China's benefit. America is truly “exceptional,” and the envy of every political system the world over, because our system is anchored on the rule of law and institutions that allow stakeholders' competing interests to be adjudicated. All parties have had many years to make their cases. The FCC's world-class scientists and engineers have come to a conclusion. The DoD has no new information; it just does not like the result. After all the internal policy battles are fought, there is only one constituency that matters: the American people and their national and economic security, consistent with U.S. policy objectives grounded in facts. This is why we must embrace this scientifically sound and strategically wise decision by the FCC and move forward, guided by another more apt principle of war: unity of effort. https://www.c4isrnet.com/opinion/2020/04/24/recalculating-gps-l-band-and-the-pentagons-untenable-position-on-5g/

  • Hypersonic threats need an offense-defense mix

    Hypersonic threats need an offense-defense mix

    By: Melanie Marlowe Next week, people from across the missile defense community will gather at an annual symposium in Huntsville, Alabama, to consider how to adapt U.S. missile defense efforts to the challenge of renewed competition with Russia and China. A centerpiece of their discussions will be the emergence of advanced hypersonic missile threats and what to do about them. Over the past few years, the Pentagon has prioritized the development of offensive hypersonic strike weapons, with billions of dollars in contracts already awarded for each of the major military services to acquire hypersonic strike missiles of their own. The counter-hypersonic mission, however, received surprisingly short shrift in recent defense budgets, with progress on hypersonic defense thus far piecemeal and halting. Some leading military officials charged with procuring hypersonic strike missiles have said that defending against hypersonic missiles is too hard, so we shouldn't even try. That short-sighted approach is at odds with the vision of newly confirmed Secretary of Defense Mark Esper, who stated to Congress that he will advocate hypersonic missile defense, to include the development of new sensors, interceptors, and advanced command-and-control systems. Public commentary on hypersonic threats has been somewhat hyperbolic. Yes, hypersonics are fast — five or more times the speed of sound — but that's slower than many ballistic missiles. Aerodynamic maneuver makes for a less predictable flight path, but this also means that atmospheric friction would remove the kind of decoys that might accompany a ballistic reentry vehicle. Whether a boosted glide vehicle, a scramjet cruise missile or a maneuverable quasi-ballistic missile, hypersonics pose a complex air defense challenge, but they are not invulnerable. The strategic significance of hypersonics is nevertheless quite real. Today's Patriot, Terminal High Altitude Area Defense and Aegis defenses protect American carrier groups and ground forces against aerial and ballistic missile attack. Designed to go around or under those defenses, hypersonics are a more sophisticated means to hold forces at risk, and thereby undermine our broader defense goals and alliance system. Even if the United States catches up with the Chinese and Russians on hypersonic strike, our adversaries' ability to hold U.S. carriers and forward bases at risk will push back U.S. forces. They could certainly also be used to target the American homeland, but the more urgent threat is regional. Passive defense only goes so far — ships can only go so fast, and air bases cannot be moved. Active defenses must be part of a balanced strategy. The first priority here is a space sensor layer. Unlike ballistic missiles, hypersonic missiles fly at lower and changing altitudes, are harder to see, and travel an uncertain flight path. Current early warning satellites can detect the launch of boost-glide vehicles but are unsuited to tracking them during the glide phase. Today's surface-based ballistic missile radars would only be able to spot a weapon once it crosses the horizon. Only space sensors can provide birth-to-death, fire-control quality tracks for hypersonic missiles. Unfortunately, recent budget requests have been rather tepid in their commitment to space sensors. The administration's 2020 request virtually divested the program, and for the second year in a row the Missile Defense Agency listed the space sensor layer as its No. 1 unfunded priority. Thankfully, Congress seems to be in the process of restoring $108 million to return the program to the MDA to move out on development this year. The second element of hypersonic defense is interceptors. Although existing interceptors may well be improved, Secretary Esper has affirmed that new interceptors will have to be developed that are better suited to the mission's stressing thermal and high-maneuver environment. The MDA's third-highest unfunded priority for 2020 — $720 million for hypersonic defense — seems unlikely to be restored this year, but should be restored in the 2021 budget. Directed-energy weapons could potentially target hypersonic threats in their cruise phase or jam them in their terminal phase, but the mission's complexity will almost certainly require both kinetic and nonkinetic effectors. The most challenging element will be developing a command-and-control architecture that ties everything together. A long-range hypersonic glide vehicle of significant range could cross continents and multiple combatant commands. Even with better interceptors and an adequate sensor layer, information and fire-control solutions must be developed and rapidly passed to commanders. The Command and Control, Battle Management, and Communications network that supports the Ballistic Missile Defense System may be the foundation of such an architecture, but more dramatic upgrades will be required. The advent of the hypersonic era is central to the efforts by Russia and China to counter U.S. power projection in the world. The Pentagon's recent focus on hypersonic strike is necessary but insufficient. It falls now to congressional leadership and those assembling the 2021 budget to rebalance it with a more appropriate mix of hypersonic strike and defense. https://www.defensenews.com/opinion/commentary/2019/08/02/hypersonic-threats-need-an-offense-defense-mix/
