"The A-12 I did terminate. It was not an easy decision to make because it's an important requirement that we're trying to fulfill. But no one could tell me how much the program was going to cost, even just through the full scale development phase, or when it would be available. And data that had been presented at one point

1767-760: The Paris Airshow 2013, Pratt & Whitney President David Hess said he was confident that Canada would decide to stick with the F-35 program despite its recent discussions about having a new competition. If the orders did shift to another company, Pratt & Whitney could decide to move some of the industrial base work it is currently doing in Canada, Hess said. "We might reallocate the work elsewhere", he said, adding that reduced order volumes would likely trigger changes in Canada. The division admitted in July 2012 to providing engines and engine software for China's first attack helicopter,
