A US Navy P-8A Poseidon, an anti-submarine and anti-surface warfare aircraft, flying over the Mediterranean Sea on Wednesday was intercepted by a Russian Su-35 fighter jet, the Navy said.

"The interaction was determined to be unsafe due to the SU-35 conducting a high-speed, inverted maneuver, 25 ft. directly in front of the mission aircraft, which put our pilots and crew at risk," the Navy said.

The Navy said the crew of the P-8A Poseidon experienced "wake turbulence" during the 42-minute encounter.

The US Navy said on Wednesday that one of its aircraft was intercepted by a Russian jet while flying in international airspace over the Mediterranean Sea.

The US Navy P-8A Poseidon, an anti-submarine and anti-surface warfare aircraft, was flying over the Mediterranean Sea when it was approached by a Russian Su-35 fighter jet, US Naval Forces Europe-Africa said.

"The interaction was determined to be unsafe due to the SU-35 conducting a high-speed, inverted maneuver, 25 ft. directly in front of the mission aircraft, which put our pilots and crew at risk," the Navy said in a statement.

"While the Russian aircraft was operating in international airspace, this interaction was irresponsible," the Navy added. "We expect them to behave within international standards set to ensure safety and to prevent incidents."

A Russian Su-35 jet performed a similar maneuver toward a P-8A Poseidon over the Mediterranean Sea in June. The jet buzzed the US aircraft three times in three hours and conducted a pass directly in front of it.

"This interaction was irresponsible," the Navy said in a statement at the time.

On both occasions, the Navy said its aircraft was flying in international airspace and was not provoking the Russian aircraft.

Russia performed another provocative test by firing an anti-satellite missile on Wednesday, US Space Command said.

Russia's direct-ascent anti-satellite test "provides yet another example that the threats to US and allied space systems are real, serious and growing," Gen. John Raymond, the head of Space Command and chief of space operations for US Space Force, said in a statement.

"The United States is ready and committed to deterring aggression and defending the nation, our allies and US interests from hostile acts in space," Raymond added.
