    'Shields Up': Defence Department looks for new ways to protect Canada's satellites, with a nod to Star Trek

    Enemy action against satellites could include cyber-attacks, jamming, lasers or missiles, while natural threats could be solar flares or space weather The Defence Department wants to take a page out of Star Trek and has asked researchers to develop ways to protect Canadian satellites from such threats as laser attacks and missiles. Dubbed the “Shields Up” project, the plan would see the development of innovative capabilities that could be incorporated into the design and operation of Canada’s space-based systems. The Shields Up terminology is a nod to the sci-fi TV and movie series Star Trek in which the USS Enterprise starship is protected by deflector shields that can be instantly activated in response to a threat. “Satellites are vulnerable to natural and artificial threats as well as, increasingly, threats from adversaries who seek to disrupt or destroy allied space systems,” said Dan Le Bouthillier, a spokesman for the Department of National Defence. Enemy action against satellites could include cyber-attacks, jamming, lasers or missiles, while natural threats could be solar flares, space weather or collisions with debris in space. The Defence Department and the Canadian Forces are the only Canadian entities with the mandate of protecting and defending the country’s space capabilities, Le Bouthillier noted. The call for proposals is part of a DND science innovation program. Ideas that are accepted will receive $200,000 to further the proposal over a six-month period. The most promising solutions could receive another $1 million for additional development, Le Bouthillier said. Most satellite services are commercial in nature and defensive measures have not been a primary criteria in their design. But the DND wants that to change. The concepts or designs have to provide a reasonable method to deal with the threat. They also have to take into account Canada’s international relations and obligations and the fact that various satellites operate in different orbits, which could influence the type of threats they face. There are 1,950 operational satellites in Earth orbits. Le Bouthillier said militaries are increasingly dependent on space-based systems for communication, surveillance, environmental monitoring and navigation. The DND has a growing interest in keeping Canadian space systems safe. In August the department put out a request to Canadian scientists to try to come up with a way to rid the Earth’s orbit of the millions of pieces of space junk that pose a threat to satellites and other spacecraft. But the task is daunting; no other researcher has figured out how to collect the debris, which can be as small as one millimetre. The DND noted that the request at this point is not about funding a system but investigating new ideas to eliminate the space junk. The total number of “debris objects” in orbit is estimated to be about 129 million. That includes 34,000 objects greater than 10 centimetres in size, 900,000 objects one cm to 10 cm, and 128 million objects one mm to one cm, according to the DND. The debris has been created by decades of space travel and operations. In 2007, for instance, China conducted a military test using a missile to destroy one of its satellites. The warhead obliterated the spacecraft, creating an estimated 300,000 pieces of debris. The U.S., Russia and India have conducted similar military experiments. “There are no operational debris removal capabilities in use, globally, and existing prototypes lack important capabilities and have proven ineffective,” the DND noted in its request to researchers. DND is also interested in ways to track some of the smaller pieces of space junk as well as methods to remove multiple pieces of debris of any size. Space surveillance networks regularly track about 22,300 objects in Earth orbits. https://nationalpost.com/news/canada/shields-up-defence-department-looks-for-new-ways-to-protect-canadas-satellites-with-a-nod-to-star-trek

    French and Italian governments endorse long-shot bid for 15 new ships for Canada's navy

    DANIEL LEBLANC OTTAWA PUBLISHED DECEMBER 8, 2017UPDATED 3 DAYS AGO The French and Italian governments are officially backing an unsolicited proposal to supply 15 military vessels to the Royal Canadian Navy outside of the ongoing competition for the $60-billion contract, documents show. The French and Italian ministers of defence submitted a letter last month to their Canadian counterpart, Harjit Sajjan, stating that they "fully support" the joint bid by Naval Group and Fincantieri to replace the RCN's existing frigates and retired destroyers. The support from the French and Italian governments could give additional weight to the long-shot proposal, which aims to bypass the official procurement process for new Canadian Surface Combatants. "Under the umbrella of an intergovernmental agreement, we will provide project management support so that the Royal Canadian Navy can operate the purchased warships, sustain their operational capabilities and manage their evolving capabilities throughout their entire lifecycle," said the letter from French Defence Minister Florence Parly and Italian Defence Minister Roberta Pinotti. The submission from Naval and Fincantieri has shaken up the process put in place by the federal government to acquire 15 new vessels. Halifax-based Irving Shipbuilding Inc. is the government's prime contractor, with a competition under way to select a warship design. Defence-industry sources said the leading contender in the process is a joint bid by U.S.-based Lockheed Martin and British-based BAE Systems. The same sources said only three of the 12 prequalified bidders submitted a formal proposal by the Nov. 30 deadline, a number the federal government will not confirm. Under Canada's defence policy unveiled earlier this year, the federal government is planning to get its first Canadian Surface Combatant in 2026, with the entire project costing between $56-billion and $60-billion. Under the Franco-Italian proposal, the 15 vessels would also be built at the Irving shipyard. Based on production costs in Europe, the two companies said they could provide the vessels to the Canadian government for $20.9-billion (€13.8-billion), with construction starting in late 2019. The bid from Naval and Fincantieri was unsolicited, essentially relying on the possibility that none of the bidders under the existing process will be deemed compliant. The defence-industry sources described the offer as a "Hail Mary" that could succeed if the ongoing process unravels, like many previous military procurements. "Everything depends with what happens with the process that is under way right now," said David Perry, senior analyst at the Canadian Global Affairs Institute. "If they can get two compliant bids or ideally all three … I wouldn't see a need to go back and do a comparison with the [Naval/Fincantieri] bid." The federal government said this week that it will not even analyze the unsolicited bid. "To be clear, any proposals submitted outside of the established competitive process will not be considered," Public Services and Procurement Canada (PSPC) said in a statement. "The submission of an unsolicited proposal at the final hour undermines the fair and competitive nature of this procurement suggesting a sole-source contracting arrangement. Acceptance of such a proposal would break faith with the bidders who invested time and effort to participate in the competitive process, put at risk the government's ability to properly equip the Royal Canadian Navy and would establish a harmful precedent for future competitive procurements," the statement said. In addition, the government rejected the notion that the Franco-Italian bid could generate significant savings, stating that the acquisition of the ships accounts for only about half of the price tag. "It is important to note that a warship project budget must cover more than just delivering the ships. It must also include the costs associated with design and definition work, infrastructure, spare parts, training, ammunition, contingencies and project management," PSPC said. The Naval/Fincantieri proposal is based on the European multimission frigate program, under which the two firms are supplying 18 ships to the French and Italian navies. The two companies said their "off-the-shelf solution" is less risky than other projects still in development. https://www.theglobeandmail.com/news/politics/french-and-italian-governments-endorse-long-shot-bid-for-15-new-military-ships/article37275099/ CSC
