  Huntington Ingalls wins $175 million Navy contract for aircraft carrier maintenance work

  By DAVE RESS Huntington Ingalls Industries will provide maintenance, training and planning support for aircraft carriers over the next five years under a new contract worth up to $175 million. The contract covers engineering services, maintenance and operator training as well as technical and repair services. The focus is on continuing maintenance of the carriers' shipboard elevators and cargo-handling equipment, as well as on planning for the overhaul, modernization and repair of these systems. The work, contracted by Naval Sea Systems Command, will be performed onboard U.S. naval aircraft carriers in Norfolk, San Diego, Washington State and Japan. The elevators on the new USS Gerald R. Ford-class carriers built at HII's Newport News Shipbuilding yard represent a major redesign, using electric motor systems to replace hydraulic mechanisms that can leak flammable fluids in areas where bombs and other munitions are prepared. Last year, a team of Newport News Shipbuilding engineers and shipbuilders worked up a new design for the rails on which Ford-class carrier weapons elevators travel. The adjustable bedplate, deemed a “total rethinking of the entire stator installation process,” turned a 56-step installation process into a 16-step effort, eliminating 95% of the welding and 50% of the rigging. That simplifies the work of aligning the rails -- a task which much meet tolerances of a sixteenth of an inch or less over distances equivalent to several stories of a building. Those alignments are a key issue for certifying the 11 elevators on the Ford, work set for completion this spring. Separately, the Military Sealift Command awarded East Coast Repair and Fabrication a $12.1 million contract for repairs and maintenace work on the USNS Kanawaha to be done at East Coast's new Newport News facility. Kanawaha is a fleet oiler, designed to supply fuel to Navy ships at sea. It has been in service since 1991 and is assigned to the Atlantic Fleet. The work includes some structural and electrical work, and the contract includes options which if exercised would increase its value to $13.6 million. The work is expected to be completed by April 19.

  Canadian satellites vulnerable to cyberattack, internal Defence note warns

  Jim Bronskill / The Canadian Press OTTAWA — Satellites vital to Canadian military operations are vulnerable to cyberattack or even a direct missile strike — just one example of why the country's defence policy must extend fully into the burgeoning space frontier, an internal Defence Department note warns. The Canadian military already heavily depends on space-based assets for basic tasks such as navigation, positioning, intelligence-gathering, surveillance and communications. Canada is also working on the next generation of satellites to assist with search-and-rescue and round-the-clock surveillance of maritime approaches to the country, including the Arctic. But those important roles could be endangered as technological advances and lower costs allow more countries, including adversaries, to cause trouble in orbit. Powers such as China and Russia are developing the ability to wage technological attacks in space, the note points out. "Easier access could also open the door to non-state actors or to failed states with nothing to lose from disrupting space." Canada's new defence policy underscores the importance of space, creating a need for "innovative investment" to ensure National Defence has the tools and know-how to fend off threats, the internal document adds. A copy of the note, Space Technology Trends: Threats and Opportunities, was recently obtained by The Canadian Press through the Access to Information Act. Several sensitive passages were stripped from the note, prepared last November for the deputy minister of National Defence. In a statement, the department called the intention to protect and defend military space technology a "very important change" in the new policy. "What 'defending and protecting' these assets means in practice will evolve, as technology and international discussions mature." Despite public perception, the militarization of space actually happened decades ago, said Dave Perry, vice-president and senior analyst at the Canadian Global Affairs Institute. "Militaries the world over depend on an extraordinary amount of infrastructure that's space-based, even if there are no physical weapons in space," he said in an interview. "Space is well-emerged, but we keep calling it emerging." Even so, the internal note points out space is becoming ever more congested due to the advent of commercial space companies and the dawn of space tourism. "In addition, more and more nations are becoming space-capable and will expect their share of access to space." The most direct threat to Canada's space capabilities comes from adversaries with the ability to attack satellites, the note bluntly states. China, for example, has demonstrated the ability to destroy one of its aging low-orbit weather satellites with a ballistic missile, creating plenty of space debris. Other possible tactics include a directed energy attack, electronic jamming or a cyberattack, which can temporarily or permanently disable a satellite, the note adds. It says Canada is working with the U.S. and other allies on the idea of being able to quickly dispatch replacements for critical space assets that are damaged or destroyed. As artificial intelligence becomes more prevalent in operating space technology, such as a robotic arm, it will be easier for a hostile player to sabotage it, Perry said. "If you can figure out a way to affect the software, then that's a potential vulnerability. Whereas before you would have (needed to fly) someone there, and actually put them on the piece of equipment, to be able to do something." High-resolution images of the Earth captured by space satellites, once exclusive to the military, have become increasingly available to other government agencies, companies, the public and hostile players — essentially "whomever is willing to pay," the note says. The accessibility of this data and the ability to link it with other sources, such as social media, "will present immense challenges" to privacy and public safety. As space-based sensing and communication technologies rapidly improve, they become capable of scooping up more information, creating another headache for the military, the note says. "The challenge of collecting, handling, storing, processing and accessing this data will become more and more severe as the data volume, velocity and variety continues to increase." — Follow @JimBronskill on Twitter https://www.richmond-news.com/canadian-satellites-vulnerable-to-cyberattack-internal-defence-note-warns-1.23474192
