Russia has sent its most advanced fighter jet to Syria, a US military official reports.
It’s a deployment that could potentially increase the level of danger to US forces operating inside the country.
The Su-57 is Moscow’s most sophisticated military jet and comes equipped with stealth capability.
Russia’s move comes despite a promise from President Vladimir Putin to scale back Russia’s military commitment in the country.
The deployment comes on the heels of the United States employing its most advanced fighter jet, the F-22 stealth fighter.
It is unclear if their deployment is a response to US deploying F-22s to the region or if Russia is using the Syrian theater as an opportunity to test the new aircraft.
The Su-57 is the first Russian military fighter to use stealth technology and is designed for aerial combat and ground-attack operations.
According to the Russian Defense Ministry, the jets were scheduled to be introduced to Russian forces in 2018, and a total of 12 aircraft were initially ordered by the Russian government.
