  For US Air Force pilots, the toughest training flights are going virtual

  By: Valerie Insinna NELLIS AIR FORCE BASE, Nev. — A new simulator campus at Nellis Air Force Base could be key for the U.S. Air Force as it grapples with the question of how it can train pilots against complex threats like Russia and China at a budget-friendly cost. On Aug. 17, the Air Force opened the doors of the Virtual Test and Training Center, or VTTC, a new, $38 million building where pilots will practice advanced tactics in a simulated environment that replicates war against a near-peer nation. “When you think about great power competition and where we might have to fight — shipping out to fight a China or Russia, particularly — there is no live training venue for the joint force, certainly for the Air Force, that's big enough, that has the threat density that can replicate what China or Russia can do,” said Maj. Gen. Chuck Corcoran, who leads the U.S. Air Force Warfare Center at Nellis. While live exercises will remain an important component of pilot training, the VTTC will give the Air Force a way to simulate a vast battlespace populated by high-end threats. Users will be able to network with other pilots on the system — who fly F-16s, F-22s, F-35s and F-15Es, with perhaps more to come — and fly complex missions against virtual enemies that are impossible to emulate in live training exercises like Red Flag. The VTTC building, which Defense News toured during an Aug. 21 visit to the base, is currently empty. But it won't stay that way for long, said Lt. Col. Chris Duncan, an F-35 operational test pilot and commander of Detachment 1, 29th Training Systems Squadron. F-15E Strike Eagle simulators are slated to be delivered to the center in October and will go online in April 2021. The joint simulation environment — a government-owned virtual training environment currently under development at Naval Air Station Patuxent River, Maryland, and when finished will emulate high-end threats — is set to be fielded at the VTTC in October 2021. “Typically aircraft simulators have taught pilots how to fly them and basic employment,” Duncan said. “We're not worried about those things. We're assuming they already know that.” Instead, the training will focus on more robust mission sets, including advanced training for Air Force Weapons School students, operational testing of new platforms and large-scale war games, he said. The Air Force is deliberating how best it can expand the VTTC's capabilities over time on a limited budget. Among the factors under consideration is whether to buy additional simulators, such as ones for the new F-15EX. It may roll out the Nellis Mission Operations Network, on which the VTTC will run, to other bases such as Whitman Air Force Base in Missouri — the home to the service's only stealth bomber. There is also discussion about how to integrate the simulators on the network with live aircraft flying on the Nevada Test and Training Range, which would allow the VTTC to project synthetic threats to jets practicing midair tactics. Historically, the Air Force has been hard-pressed to fund advanced simulation efforts. The ultimate success of the VTTC may ultimately come down to whether there is enough money to continue funding simulators for additional aircraft and to keep upgrading hardware and software. Duncan said the Air Force is already keeping that point in mind. Instead of simulators that provide a completely accurate cockpit experience, the service is looking to save money by prioritizing simulators that can provide the experience of advanced missions, even if the simulator imagery or cockpit experience isn't completely realistic. But he underscored the cost-effectiveness of virtual training when compared to its live counterpart. “The payoff, the bang for the buck,” Duncan said, “it far surpasses what we can do in live flying.” https://www.defensenews.com/air/2020/08/25/for-air-force-pilots-the-toughest-training-flights-are-going-virtual/

  Canada reviews footage of destroyed and captured Canadian-made Saudi armoured vehicles

  By DAVID PUGLIESE, OTTAWA CITIZEN The Canadian government says it is examining video footage which appears to show Canadian-made light armoured vehicles captured by rebels in Yemen. Yemen's Houthi rebels released the footage Sunday of the aftermath of a battle with Saudi Arabian forces. The fighting started as an ambush inside Saudi Arabia but then turned into a major cross-border battle, according to the rebels. The footage of the battle was shown on Houthi-run Al Masirah TV and Al Jazeera. Saudi Arabia has not acknowledged the fighting and the Houthi claims have not been independently verified. The footage shows the captured and destroyed light armoured vehicles as well as Saudi troops taken prisoner. Over the years, Saudi Arabia has purchased light armoured vehicles from Canada's General Dynamics Land Systems-Canada in London, Ont. In 2014, the then Conservative government announced a deal worth an estimated $15 billion to sell Saudi Arabia more than 700 light armoured vehicles. That controversial deal was later approved by the Liberal government. Besides the armoured vehicles, the video shows large amounts of captured small arms. It is not clear whether the Houthi forces took possession of some of the armoured vehicles or left them at the ambush site. Houthi spokesman Brig. Gen. Yahya Saree told Al Masirah TV that the captured soldiers were moved to “secure places.” Doug Wilson-Hodge, spokesman for General Dynamics Land Systems-Canada, said the company is declining to comment on the footage. Global Affairs Canada spokesperson Adam Austen said Friday that department officials are reviewing the footage. It is unclear what would be done after the footage is examined. Austen also noted the government is reviewing all export permits to Saudi Arabia but no final decision has been taken. “During this review, no new permits have been issued,” Austen added. A March 21, 2016 Global Affairs Canada memo released under the Access to Information law noted that officials in the department pushed for the sale of the light armoured vehicles to the Saudis despite concerns about human rights abuses and the possibility such equipment could be captured by rebels from Yemen. The memo pointed to the appearance of a Canadian-made LRT-3 sniper rifle photographed in the hands of a Houthi rebel in Yemen. More than 1,300 sniper rifles have been exported from Canada to the Saudi Arabian military and security forces, including several hundred of that particular model, the document added. “Canada's Embassy in Riyadh assesses that this rifle, along with other Saudi military equipment, was likely captured from Saudi fighters by Houthi fighters during military operations along the Saudi-Yemeni border,” then Foreign Affairs Minister Stephane Dion was told. The Liberal government launched the review of the light armoured vehicle contract after the murder of journalist Jamal Khashoggi inside the Saudi consulate in Turkey. Earlier this year a United Nations report determined that Saudi Arabia was responsible for the killing of Khashoggi who was a critic of that country's regime. A dozen organizations sent Prime Minister Justin Trudeau a letter earlier in August, questioning the status of the review and pointing out that no updates on progress have been provided. The lack of such information has brought “the sincerity of the effort into question,” according to the letter endorsed by organizations such as Oxfam Canada and Amnesty International. Relations between Canada and Saudi Arabia soured last year after the Canadian government called for the release of two jailed Saudi human rights activists. The Saudis have also fallen behind in their payments for the light armoured vehicles received from General Dynamics. It was revealed in December that the Saudis owed Canada more than $1 billion for vehicles already delivered. A Saudi-led coalition, which has been provided with arms and intelligence from the U.S. and other western nations, intervened in Yemen in 2015 after the Houthis overthrew the government. Saudi Arabia has faced severe criticism for its role in the ongoing war in Yemen, with allegations it has conducted unlawful airstrikes on civilians.
