  New armoured vehicle fleet faces more problems – civilian vehicle hit near Petawawa

  DAVID PUGLIESE, OTTAWA CITIZEN The Canadian military is investigating potential problems with brakes on its new armoured vehicle fleet which may have contributed to a number of incidents, including where one of the 18-tonne vehicles hit a car near Petawawa. There have been eight reported incidents involving problems with stopping or issues with brakes affecting the Tactical Armoured Patrol Vehicles, or TAPVs. A formal safety advisory was issued Feb. 12 to the army units using the $600-million TAPV fleet. But the use of the vehicles is not being restricted at this time. The brake issues started being reported in January 2018 and the intermittent problem has only occurred at speeds in the range of five to 15 kilometres an hour, according to the Canadian Forces. “We are working with experts to try and determine if there is a problem with the vehicles braking performance at low-speed, and if the problem is isolated to a few vehicles or the result of something that may affect the wider fleet,” noted army spokesman Lt.-Col. Doug MacNair. So far, the Canadian Forces and Department of National Defence has been unable to replicate the reported problem, nor have inspections uncovered any obvious causes. There have been no injuries as a result of the incidents. Among the eight incidents is a Feb. 3 accident during which a TAPV rolled through a red light and hit a civilian vehicle near Canadian Forces Base Petawawa. No injuries were reported, and Ontario Provincial Police issued a ticket to the TAPV driver for failing to stop at a red light. Driver error was the “apparent problem” according to the Canadian Forces. But sources point out the driver in question reported problems with the TAPV brakes. During a change of command parade in Halifax in November 2019 a TAPV hit a wall causing minor damage after the brakes failed to stop the vehicle. A soldier near the vehicle had to “take evasive action to avoid being struck,” according to the Canadian Forces. In one case the brakes on a TAPV caught fire. In the aftermath of several other incidents involving brake failure large amounts of ice were found in the brake drums. In another case a TAPV hit the side of a bridge during training. “Following each of these incidents, technicians were unable to locate a problem with the brakes after they conducted technical inspections,” the Canadian Forces added. In 2016 the TAPV fleet had brake issues. At that time it was determined the anti-lock braking system on the vehicles was engaging erratically at higher speeds. A retrofit was introduced across the entire fleet to deal with that problem. The military says there is no evidence to suggest a connection between the 2016 braking issues and these latest incidents. Last year this newspaper reported on a series of rollovers and fires affecting the TAPV fleet. Between April 2014 and January 2019 there had been 10 incidents when Tactical Armoured Patrol Vehicles have tipped on to their sides, six where they have rolled over completely, and four where they have caught fire. Pat Finn, then the assistant deputy minister in charge of procurement at the Department of National Defence, said at the time there have been no serious injuries as a result of the incidents. Finn suggested the rollovers might be caused because of the high centre of gravity the vehicles have. Training was improved to deal with the issue of rollovers. No explanation was provided at the time for the cause behind the fires. The TAPVs have also faced other problems, according to DND documents obtained by this newspaper using the Access to Information law. The TAPV program has “experienced a number of significant technical issues, particularly affecting vehicle mobility,” then-Conservative defence minister Rob Nicholson was told in August 2014. There have been problems with the suspension, steering and other items on the vehicle, according to the briefing document for Nicholson. The technical issues significantly delayed the test program for the vehicles, the document added. The Conservative government announced the TAPV contract in 2012 as part of its re-equipping of the Canadian Army. Canada bought 500 TAPVs from Textron, a U.S. defence firm, at a cost of $603 million. The TAPV is a wheeled combat vehicle that will conduct reconnaissance and surveillance, security, command and control, and armoured transport of personnel and equipment. The TAPV project cost taxpayers a total of $1.2 billion, which not only includes the vehicles but also includes the building of infrastructure to house them, as well as the purchase of ammunition and service support for the equipment. https://ottawacitizen.com/news/national/defence-watch/new-armoured-vehicle-fleet-faces-more-problems-civilian-vehicle-hit-near-petawawa

  HMCS Corner Brook to become first sub equipped with new communications system

  DAVID PUGLIESE, OTTAWA CITIZEN HMCS Corner Brook will be the first Canadian submarine to be equipped with a new communications system. The Universal Modular Masts or UMM for Canada's Victoria class submarines are part of an equipment suite provided by the Protected Military Satellite Communications project, according to the Department of National Defence. The estimated project cost for the submarine equipment suite, including installation, is approximately $70 million, while the overall PMSC project cost is approximately $592 million. The Protected Military Satellite Communication project is in collaboration with the U.S. and other allied nations and provides the Canadian military with secure, protected, jamming-resistant satellite communications on a near world-wide basis. The UMM will improve the Victoria-class as an intelligence, surveillance and reconnaissance platform, according to the DND. The mast and its associated equipment suite will provide near real-time high-speed communications with shore. Corner Brook is in its Extended Docking Work Period and installation of the mast is now underway. Babcock Canada Inc. is handling the installation under the aegis of the Victoria In-Service Support Contract. It is being done at CFB Esquimalt in British Columbia. The equipment was acquired through a foreign military sales acquisition. The cost for PMSC-supplied submarine equipment, including UMMs, is approximately $35 million, according to the DND. Installation of the UMM on Corner Brook will be complete in 2020. Installation on the other three submarines will be finished by 2026. https://ottawacitizen.com/news/national/defence-watch/hmcs-corner-brook-to-become-first-sub-equipped-with-new-communications-system

  RCAF working toward new sniper pod placement on CF-188 Hornet

  Chris Thatcher In a two-by-three metre wind tunnel at the National Research Council of Canada's (NRC) aerospace research centre in Ottawa, aerospace engineers are gathering data for the Royal Canadian Air Force (RCAF) this week to validate the placement of the sniper pod on the centreline station of the CF-188 Hornet. “For this configuration, we are running at close to takeoff and landing speeds to simulate the take off and landing of the F-18, about 100 metres per second or almost 200 knots,” explained Melissa Richardson, an aerodynamics research officer and the project manager for the testing process, as wind whipped over the inverted nose landing gear and sniper pod. The CF-188 fighter jet has carried a certified sniper pod on the left side of the fuselage, below the engine intake, since the aircraft were upgraded in the early 2000. But lessons from recent operations over Libya in 2011 and Iraq and Syria between October 2014 and March 2016 convinced pilots they would have a better view of possible targets with the centerline placement. “We found a lot of our missions revolved around looking at the ground, monitoring areas of interest and targets for missions that are four to five hours long,” said Capt Tom Lawrence, a CF-188 pilot and the project officer for fighter weapons and equipment. “When [pilots] are manoeuvring their aircraft, there is a chance of the aircraft actually masking the targeting pod. Putting [it] on the centre of the aircraft allows a larger field of regard.” Rather than bank left to maintain focus on a target, the new placement should ensure an uninterrupted view of the ground or target aircraft, “taking that frustration out of the pilot's mind,” he said. “They can just focus on the imagery and the task at hand.” Lawrence said it could also make it easier for pilots to employ weapons and assess battle damage effects. The purpose of the wind tunnel tests is to measure the aerodynamics created by the nose landing gear on the sniper pod mounted behind it at times when it is most exposed to turbulence, said Richardson. Among concerns before the tests began were the effect of significant vibration on the pod and the possibility of debris being kicked up by the wheels and striking its protective glass shield. “[We need to] make sure the aircraft is safe to operate with the sniper pod on this new location. That means it can take off and land without excessive vibration, that the loads are still within acceptable limits,” explained Capt David Demel, the certification authority with the RCAF's Technical Airworthiness Authority. “This is the goal of the current wind tunnel test, to confirm that before we move to the flight test phase in Cold Lake in the September timeframe.” A second a high-speed equivalent test will be conducted by the NRC at its high speed trisonic wind tunnel in about three weeks, using a six per cent scale model, that will include ensuring engine intake airflow is not affected. Test pilots with the Operational Test and Evaluation Unit in Cold Lake will then recertify operational airworthiness of the sniper pod in its new placement. While the testing facilities are being provided by the NRC, the vibration data is being gathered and analyzed by Bombardier, which has provided some of the instrumentation. The sniper pod and landing gear were installed in the wind tunnel by L-3 MAS, which will have the task of mounting the pods in the new location on the entire CF-188 fleet–including the 18 F/A-18 Hornets the government is negotiating to buy from the Royal Australian Air Force–once approved. “We're all collaborating on the project as it goes through each phase, from technical airworthiness to operational airworthiness,” said Lawrence. https://www.skiesmag.com/news/rcaf-planning-new-sniper-pod-placement-cf-188-hornet/
