In 2008 and 2009, personnel shortages reduced the number of submarines able to be deployed to three; the maintenance cycles of "Sheean", "Rankin", and "Dechaineux", and problems with "Collins" and "Waller" further reducing this to one, "Farncomb", in mid-2009. "Farncomb" was docked for repair after a generator malfunction in February 2010, by which point "Collins" and "Waller" were active (the former on limited duties because of defects), and "Dechaineux" was slated to re-enter service by May 2010. Workforce shortages and malfunctions on other submarines during the preceding two years impacted heavily on the maintenance of "Sheean" and "Rankin", with RAN and ASC officials predicting that they will not be active until 2012 and 2013, respectively. In June 2011, "The Australian" newspaper claimed despite two submarines ("Waller" and "Dechaineux") designated as operational, neither was in sailable condition. The initial findings from the Coles Review revealed significant, systemic problems with the submarines and noted the need for their management to be reformed. A 2014 statement by Vice Admiral Ray Griggs indicated that up to four submarines had been operational on most occasions since 2012.
