In 1983 the Air Training Corps had a fleet consisting of three types of wood framed aircraft. These had reached the end of their life span and it was time to look for something new.After looking at several options the Air Cadets chose the Grob 103 or as we know it the Viking T Mk 1.

Over the next two years over 100 Vikings were delivered to RAF Syerston where they were given their service identities.

Initially our aircraft were maintained by RAF engineers at RAF Syerston. In 2008 a company called Serco were awarded a contract to maintain the aircraft.

Our aircraft were carefully looked after by one of Serco's regional teams that were based on site.

That was the case until, in April 2014, gliding operations were "paused" by 2 FTS due to a "Continued Airworthiness Issue".

When operations restarted in late 2016, maintenance was carried out by the centralised team at RAF Syerston.

There are now less than 50 Vikings in service and these need to last until at least 2025.
