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.<sup id="cite_ref-22" class="reference"><a href="#cite_note-22"><span class="cite-bracket">[</span>22<span class="cite-bracket">]</span></a></sup> </p><p>The division admitted in July 2012 to providing engines and engine software for China's first attack helicopter, the <a href="/wiki/CAIC_Z-10" class="mw-redirect" title="CAIC Z-10">Z-10</a>.
