Angus Robertson MP, the party's Westminster leader, also said the figures reveal the importance of an integrated air defence.
RAF Quick Reaction Alert aircraft were launched eight times last year, 10 times in 2011 and 11 times in 2010 after Russian military aircraft approached or entered the Nato air policing airspace which the UK patrols. The Ministry of Defence said that at no time did the Russian planes breach UK airspace.
