The
TS-11 Iskra (Spark) is a two-seat primary and advanced trainer.
The prototype first flew in 1960 and
became operational with the Polish air force in 1964.
Throughout its development, the Iskra has
incorporated more powerful engines starting with the HO-10 (1,764 lb
thrust) and continuing in 1966 with the SO-1 (2,200 lb thrust) and
SO-3 in 1972. Other improvements include the addition of light attack and
reconnaissance capabilities.
The Iskra was also used by the Indian Air Force.
