The Sukhoi Su-28 is a downgraded variant of the Su-25UB/Su-25T, with reductions in avionics and aircraft systems, together with a full reduction of weapon-carrying capability.
The Su-28 trainer is intended for technical skill, general flight and formation flying training. It is also used as a demonstrator of advanced aero-maneuvers.

[edit] Technical Description
The Su-28 is a highly maneuverable and robust aircraft with the ability to perform take-off and landing with only one of its two engines running. The aircraft's engines can also run on a diesel based fuel as opposed to more traditional aviation fuel. Like the Mig-29 it also has the ability to operate from unpaved runways while maintaining high reliability and a low maintenance requirement. It will withstand heavy landings, allowing it to be more forgiving in the training role. Range can be extended by up to four PTB-800 drop tanks, each of 800 litres capacity.
Differences between the Su-28 and it's parent Su-25UB model include the absence of targeting systems, weapon-operating systems, internal guns, wing pylons (used on military aircraft to mount weaponry such as bombs and missiles). It also lacks armor protection for the engines, advanced fly-by-wire controls, electronic countermeasures and any systems dedicated to ground attack operations.
