The Bulgarian Parliament on Friday approved the purchase of eight new US-made F-16 fighter jets for a hefty $1.3 billion (€1.1 billion).

"Bulgaria will be the first Balkan country to have this brand-new version of the aircraft," said Defense Minister Krasimir Karakachanov. 

Six of the F-16 Block 70 multi-role fighters will have a single seat while the other two will have two. They will replace the NATO country's Soviet-built MiG-29s of which only seven are still able to fly.

The F-16's manufacturer, Lockheed Martin, said the fighter jets are "a proven, capable, low-risk and cost effective solution for Bulgaria's national and NATO defense needs."

Way out of 'technological stalemate'

During a heated parliamentary debate, opposition Bulgarian lawmakers questioned the higher-than-normal price for the fighter jets.

Parliament had to widen Bulgaria's 2019 budget deficit from 0.5% to 2.1% of GDP in order to pay for the US military hardware. The deal represents the biggest defense acquisition since the fall of communism in the early 1990s.

But Bulgaria's air force chief Major General Tsanko Stoykov justified the price tag, saying the F-16s would provide Bulgaria a way out of "a technological stalemate."

Bulgaria is considered one of the poorest countries in the EU. It jointed the transatlantic NATO military alliance in 2004.
