Significant reforms were announced in late 2008 under Defence Minister Anatoliy Serdyukov (in office 2007-2012), and major structural reorganisation began in 2009. Key elements of the reforms announced in October 2008 included reducing the armed forces to a strength of one million by 2012 (planned end-date was 2016); reducing the number of officers; centralising officer training from 65 military schools into 10 "systemic" military training centres; reducing the size of the central command; introducing more civilian logistics and auxiliary staff; elimination of cadre-strength formation (military)s; reorganising the reserves; reorganising the army into a brigade system; and reorganising air forces into an air-base system instead of regiments. On 17 October 2012 the head of the State Dumas Defence Committee told RIA Novosti that Russia planned to boost annual defense spending by 59 percent to almost 3 trillion rubles ($83.3 billion) in 2015 up from $61 billion in 2012. "Targeted national defence spending as a percentage of GDP will amount to 3.2 percent in 2013, 3.4 percent in 2014 and 3.7 percent in 2015", Defence Committee chairman Vladimir Komoedov is quoted as saying in the committees conclusion on the draft budget for 2013-2015.
