  Canadian Surface Combatant

  The Canadian Surface Combatant (CSC) project is the Royal Canadian Navy's acquisition programme to build 15 CSC multi-role ships which will replace both the retired Iroquois-class destroyers and the Halifax-class frigates. The Canadian Surface Combatant (CSC) project is the Royal Canadian Navy's acquisition programme to build 15 CSC multi-role ships which will replace both the retired Iroquois-class destroyers and the Halifax-class frigates. The project is estimated to cost between $56bn and $60bn and the new warships are being built by Irving Shipbuilding at its Halifax Shipyard. The CSC has the capacity to conduct air, surface, sub-surface and information warfare missions simultaneously on both open ocean and highly complex coastal environments. The multi-mission combatant can be deployed in a range of missions such as delivering decisive combat power and supporting the Canadian Armed Forces. It can also conduct counter-piracy, counter-terrorism, interdiction and embargo missions for medium intensity operations. Canadian Surface Combatant development details The Canadian Surface Combatant project is part of Canada's National Shipbuilding Strategy and is the biggest shipbuilding activity in the country since the World War II. Irving Shipbuilding was appointed as the prime contractor for the CSC project definition and implementation phases in January 2015. The Government of Canada and Irving Shipbuilding awarded a sub-contract to Lockheed Martin Canada for the design of CSC fleet in October 2018. In February 2019, the design of BAE Systems' Type 26 Global Combat Ship, the most advanced and modern anti-submarine warship, was selected for the CSC vessel. BAE Systems opened the first visualisation suite for the CSC vessel in Ottawa, US, in November 2020. The visualisation technology will create a virtual prototype which helps in better understanding of the vessel and offers detailed view of the ship's design from all angles. Rolls-Royce Centre of Excellence facility based in Peterborough, Ontario was expanded for supporting the CSC acquisition project. Design and features of the Royal Canadian Navy's CSC ships The CSC will have a length of 151.4m, beam of 20.75m and a navigational draught of 8m. With a displacement of 7,800t, the warship will accommodate up to 204 crew members. The warship can carry a CH-148 Cyclone helicopter and provide facilities for embarking remotely piloted systems. It will also feature reconfigurable mission and boat bays including a 9m rescue boat, two 9-12m multi-role boats, Rolls Royce' mission bay handling system, and modular mission support capacity. The Canadian Surface Combatant will also house a medical facility and dedicated gym/fitness facilities. Weapons The weapons suite for the CSC will include 127mm main gun, two stabilised rapid fire 30mm naval gun systems, LMC MK 41 missile vertical launch system, 32-cell MK54 lightweight torpedoes, twin launch tubes, and MBDA Sea Ceptor close-in air defence system. The warships can be armed with a wide range of missiles including Raytheon Standard Missile 2, Raytheon Evolved Sea Sparrow point defence missile, and Kongsberg Naval Strike Missile. Command and control of Canadian Surface Combatant The warship will be installed with various command and control systems including Lockheed Martin Canada's (LMC) CMS 330 combat management system with Aegis combat system, USN cooperative engagement capability, integrated cyber defence system, OSI integrated bridge and navigation system, and L3 Harris' internal and external communication suite. Sensors and countermeasures The LMC SPY-7 active electronically scanned array (AESA) radar will be installed for continuous surveillance and protection against modern threats. The combat ship will also be fitted with MDA's solid state AESA target illuminator, X- and S-band navigation radars, electro-optical and infrared systems, laser warning and countermeasures system, radio frequency and electronic jammers, and electronic decoy system. Underwater warfare capabilities of CSC ships The Royal Canadian Navy's future combat ships will be equipped with an integrated underwater warfare system, which includes Ultra Electronics' S2150 hull-mounted sonar, towed low frequency active & passive sonar, and SEA SENTOR S21700 towed torpedo countermeasures. General Dynamics' sonobuoy processing system and expendable acoustic countermeasures will also be installed aboard the vessels. Propulsion and performance of Canadian Surface Combatant The CSC combat ship will be powered by a combined diesel-electric or gas propulsion system (CODLOG) integrating two GE electric motors, a Rolls Royce MT 30 gas turbine, and four Rolls Royce MTU diesel generators. The vessel will be able to sail at a maximum speed of 27k and achieve a maximum cruising range of 7,000nm. Contractors involved Lockheed Martin Canada is collaborating with BAE Systems, CAE, L3Harris, MDA and Ultra Electronics for the design of the global combat ship. MDA signed a $2.99m contract with Lockheed Martin Canada for the initial phase of design work of the Canadian Surface Combatant ships in April 2019. Lockheed Martin will also be responsible to provide the electronic warfare suite system. Ultra Electronics Maritime Systems will lead the integration of sensors with sonobuoys and other capabilities for wide-area underwater battlespace surveillance. https://www.naval-technology.com/projects/canadian-surface-combatant/

  '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
