The day starts with the most iconic event; the military parade through the city centre at 9:30am.
There will be over 1,300 military personnel taking part in the parade, including six bands and a military dog unit. In Hudson's Field the parade will be broadcast on big screens, so everyone will have the chance to watch it.
The celebrations take to the sky at 2pm for a display from a number of different aircraft, including an Apache helicopter, historic plane Swordfish and the Battle of Britain Memorial Flight, supported by Old Sarum Airfield.
Throughout the afternoon there will be live music performances from local musicians. Master choir leader, Gareth Malone's Invictus Choir will be performing, as well as one of the Military Wives Choirs, including other musical performances.
The evening finishes with indie rock band the Kaiser Chiefs taking to the stage and showing their support for the Armed Forces.
