It is not often that a weapon system is proving so popular that countries are waiting in line to buy it. Ironically, this appears to be the current situation with the Bayraktar TB2 unmanned combat aerial vehicle (UCAV). Already in service with or on order by 31 countries other than Türkiye, the TB2's commercial success currently looks to be without bounds. With new export agreements being signed with more countries to this day, there is little doubt that the TB2 will go down in history as world's most successful UCAV both in terms of export clients and numbers sold. In this capacity it is now consistently beating its main two competitors on the drone market of China and Israel, whose products though more attractive than expensive (and exclusive) Western wares or underperforming and politically-laden Iranian ones have shown their own deficiencies. The TB2's success should come as little surprise to those that examined the system in combat, as the TB2 is arguably the first UCAV that manages to combine reliability and affordability with devastatingly effective results on the battlefield: a capability keenly looked for in the 21st century.
