Several US Reapers have been lost in recent years, including to hostile fire

Moscow (AFP) - Moscow said Wednesday it would try to retrieve the wreckage of a US military drone that crashed over the Black Sea in a confrontation Washington blamed on two Russian fighter jets.

Russia also warned against “hostile” US flights as tensions simmered and Moscow denied its Su-27 military aircraft had clipped the propeller of the unmanned Reaper drone.

But Washington was unbowed, with Defense Secretary Lloyd Austin stressing the United States would continue flying “wherever international law allows” following an apparent de-escalation call with his Russian counterpart.

Austin called on Russia to “to operate its military aircraft in a safe and professional manner”.

Russia confirmed the call and said Washington had initiated it.

Kyiv earlier suggested the incident over international waters was evidence the Kremlin wanted to draw the United States into the Ukraine conflict.

Russian Security Council secretary Nikolai Patrushev said in televised remarks Moscow would seek to retrieve the downed craft but was unsure if the effort would be a success.

“But it has to be done. And we will certainly work on it,” he said.

The crash on Tuesday, which Washington said was the fault of reckless and unprofessional Russian conduct, further ratcheted up tensions between Moscow and Western allies, already soaring over the Ukraine conflict.

Patrushev said the incident was further proof that the United States is a direct party to fighting between Moscow and Kyiv and said Russia had a responsibility to “defend our independence and our sovereignty”.

Russia’s defence ministry said it had scrambled jets after detecting a US drone over the Black Sea and denied causing the crash.

The Pentagon said the drone was on a routine mission when it was intercepted “in a reckless, environmentally unsound and unprofessional manner”.

Russia said the aircraft had lost control but White House national security spokesman John Kirby said the US “obviously” refuted the denial.

He added the United States was trying to prevent the fallen drone from getting into the wrong hands.

“We’ve taken steps to protect our equities with respect to that particular drone – that particular aircraft,” Kirby told CNN.

- Regular intercepts -

Russian intercepts over the Black Sea are common, Kirby said, but this one was particularly “unsafe and unprofessional” and “reckless”.

Ukraine said the incident was “provoked by Russia” and cautioned that it signalled President Vladimir Putin’s aim to “expand the conflict”.

“The purpose of this all-in tactic is to always be raising the stakes,” Ukrainian National Security and Defence Council secretary Oleksiy Danilov said on social media.

Russia's campaign in Ukraine has led to heightened fears of a direct confrontation between Moscow and the NATO alliance

NATO diplomats in Brussels confirmed the incident, but said they did not expect it to immediately escalate into a further confrontation.

A Western military source, speaking to AFP on condition of anonymity, said diplomatic channels between Russia and the United States could help limit any fallout.

“To my mind, diplomatic channels will mitigate this,” the source said.

Russia’s campaign in Ukraine has led to heightened fears of a direct confrontation between Moscow and the NATO alliance, which has been arming Kyiv to help it defend itself.

Reports of a missile strike in eastern Poland in November briefly caused alarm before Western military sources concluded it was a Ukrainian air defence missile, not a Russian one.

- ‘Unflyable and uncontrollable’ -

The United States uses MQ-9 Reapers for both surveillance and strikes and has long operated over the Black Sea keeping an eye on Russian naval forces.

Pentagon spokesman Brigadier General Pat Ryder said the drone was “unflyable and uncontrollable so we brought it down”, adding that the collision also likely damaged the Russian aircraft, which he said was able to land following the incident.

Several US Reapers have been lost in recent years, including to hostile fire

Several US Reapers have been lost in recent years, including to hostile fire.

One was shot down in 2019 over Yemen with a surface-to-air missile fired by Huthi rebels, the US Central Command said at the time.

Reapers can be armed with Hellfire missiles as well as laser-guided bombs and can fly for more than 1,100 miles (1,770 kilometres) at altitudes of up to 15,000 metres (50,000 feet), according to the US Air Force.
