The PZL TS-11 Iskra (English: Spark) is a Polish jet trainer, developed and manufactured by aircraft company PZL-Mielec. It was used by the air forces of Poland and India. It is notable as being the first domestically developed jet aircraft to be produced by Poland, its service for over 50 years as the principal training aircraft of the Polish Air Force, and at the time of its retirement was the oldest jet-propelled aircraft still in service in Poland.

The PZL TS-11 Iskra is an all-metal jet-propelled trainer aircraft. It is relatively conventional in layout, featuring a trapezoid-shaped mid-wing arrangement. These wings, which only had a gentle angle of sweep along the leading edge, feature air intakes embedded into the wing root. The TS-11's single turbojet engine is accommodated within the main fuselage, its exhaust is located beneath the boom-mounted tail fin, which provides the aircraft with a fairly unusual silhouette. Both of the crew, typically being the student in the front and instructor in the back, are provided with ejector seats for emergency egress.

Some models of the TS-11 can be armed; armaments have consisted of a single nose-mounted Nudelman-Rikhter NR-23 cannon with 80 rounds, along with a total of four underwing hardpoints that were compatible with a variety of different weapons, including bombs and rockets. Most models of the aircraft lack a radar set; however, the specialised TS-11R reconnaissance variant is provided with such equipment. The TS-11 can also be outfitted with various cameras for the purpose of performing aerial photography missions. Poland is currently developing the new TS-11S Iskra (Spark) as a future jet trainer. It will be equipped with new avionics, strengthened structures and a more powerful engine..Wiki Link
