U.S. RC-135U reconnaissance aircraft was intercepted by a Russian Sukhoi Su-27 fighter jet over the Baltic Sea near Russia’s Kaliningrad Region, according to the Pentagon, which accused the Russian pilot of coming dangerously close to the US aircraft.

“On the morning of April 7, a US RC-135U, flying a routine route in international airspace, was intercepted by a Russian Su-27 Flanker in an unsafe and unprofessional manner,” the Washington Free Beacon (WFB) cited Pentagon spokeswoman Eileen M. Lainez as saying.

The official said that a Russian Su-27 (NATO designation – Flanker) passed within a few meters of the unarmed reconnaissance aircraft, whereas the Sukhoi’s wingspan is 14.7 meters. The Pentagon spokeswoman dubbed the behavior of Russian pilot “reckless” and endangering the safety of the RC-135 crew.

Major-General Igor Konashenkov, spokesman for the Russian Defense Ministry, said that the interception was launched after “Russian air defense radars spotted an unidentified air target over the Baltic Sea making steady progress toward the national border.” The aircraft had its transponder turned off, Konashenkov said.

The Sukhoi Su-27 dispatched to intercept the target identified it as a US Air Force reconnaissance aircraft RC-135U and reported the aircraft’s type and tail number to headquarters. After the Su-27 made several fly-bys around the spy plane, the RC-135U altered course and moved away from Russian border.

“No emergency situation was reported during the fly-by of the American reconnaissance aircraft,”Konashenkov said.

The RC-135 is a military version of a Boeing-707 and the intercepted RC-135U version is code-named Combat Sent, specializing in gathering intelligence on “enemy electronic signals and radar emitters.”

No details have been released on the mission of the RC-135, but the aircraft was reportedly in a position to monitor Russian military activities in western Russia and Kaliningrad.

It is in the Kaliningrad exclave where Moscow recently decided to deploy Iskander-M nuclear capable tactical quasi-ballistic missile systems.

The head of Russia’s Upper House Committee for Foreign Relations, Konstantin Kosachev, called on to NATO to stop their “hysterics” over flights by the Russian Air Force, “presenting them as aggression and demonizing Russia.”

“In connection with the incident over the Baltic one should keep in mind that Russia is a Baltic country, whereas the US is not,” Kosachev said.

On Tuesday, the same day that the incident with the RC-135U took place, the commander of the US Northern Command, Adm. William Gortney, expressed concern at the increase in Russian military flights.

“They are messaging us,” he told reporters at the Pentagon. “They’re messaging us that they’re a global power – we do the same sort of thing – with their long-range aviation,” Gortney said, noting that Moscow has adopted a new strategic doctrine.

Details about RC-135U Airplane:

The RC-135U Combat Sent is designed to collect technical intelligence on adversary radar emitter systems. Combat Sent data is collected to develop new or upgraded radar warning receivers, radar jammers, decoys, anti-radiation missiles, and training simulators.

RC-135 U

Distinctly identified by the antennae arrays on the nose, tail, and wing tips, three RC-135C aircraft were converted to RC-135U (63-9792, 64-14847, & 64-14849) in the early 1970s and 63-9792 was converted to Rivet Joint, late 1978, and all aircraft are based at Offutt Air Force Base, Nebraska.

Su-30MKI prototype and Kh-31 (AS-17 Krypton)

Kh-31P (AS-17 Krypton) – 55nogl

high-speed medium-range “air-to-surface” guided missile with changeable passive radar homing heads is designed to engage radars operating within long- and medium-range air defence missile systems, as well as other ground- and sea-based radars of different purpose, in the corresponding frequency band.

The Kh-31P missile can be efficiently launched either independently or in salvo, in fair and adverse weather conditions, to engage radar targets of opportunity or previously disclosed ones.

The missile can be equipped with changeable homing heads operating in corresponding frequency bands used by modern continuous-wave and pulsed radars of surface-to-air missile and anti-aircraft artillery systems.
