The decision followed high-level military talks between the two countries in Ankara, where Turkey agreed to supply the aircraft plus spares “gratis” to Islamabad.
Gen Naveed Ahmed, director general of defence procurement for Pakistan, signed the agreement with Maj Gen Serdar Gulbas, the Turkish chief of logistics.
Pakistan already operates 18 T-37s that entered service in June this year, and the only other current operator of the T-37 is the Columbian air force, Flightglobal’s Fleets Analyzer database shows.
Turkey's air force retired the T-37s in around 2009, replacing them with 40 Korea Aerospace Industries KT-1 trainers that were delivered this year. An additional 15 examples are covered by a letter of intent.
