London 2012 - One extraordinary year
During the Olympics, the Typhoon fighter jets - normally based at RAF Coningsby in Lincolnshire - will move to RAF Northolt in London.
Other measures will include placing snipers in helicopters, as well as having Rapier air defence missiles on high alert status.
More than 13,000 servicemen and women will be involved in addition to civilian security staff.
Sqn Ldr Gordy Lovett said: "The Typhoon is a world-class interceptor aircraft and we're very able and capable of doing the alert mission - identifying and intercepting aircraft that are potentially a threat.
"That could be from a lost general aviation aircraft up to a high-potential threat.
"We're able to go and identify those and then carry out extra measures as required to ensure the safety and security of the airspace is maintained."
