The Estonian Air Force is to replace the two Antonov An-2 'Colt' transport aircraft it operates in favour of a pair of Shorts C-23 Sherpas, a service official disclosed on 17 December.
Speaking during a media tour of Amari Airbase, 2nd Lieutenant Pille Joala said that the An-2s, which have been in Estonian service since 1996 but date back to the former Soviet Union,
will continue to operate until the end of 2015,
before being replaced by two Sherpa aircraft that are to be procured from the United States.
According to Lt Joala, herself an An-2 pilot,
the Sherpas should arrive in Estonia a few months before they are due to take over the light transport role from the An-2,
and that the seven pilots assigned to the An-2 will shortly begin conversion training.

Yes, the Shorts cannot do some work that the Antonov An-2 CAN do...
