A Russian fighter spent 90 minutes making low-level passes near a U.S. ballistic missile defense (BMD) guided missile destroyer on station in the Black Sea, a defense official told USNI News on Monday.
The incident occurred on Saturday when a Sukhoi SU-24 Fencer flew as close as 1,000 yards from USS Donald Cook (DDG-75) at an altitude of only 500 feet, the official said.
The fighter made up to 12 passes on the destroyer after not responding to several attempts by the ship to contact the Fencer via radio. There was a second SU-24 in the region but did not engage Cook.
“This provocative and unprofessional Russian action is inconsistent with international protocols and previous agreements on the professional interaction between our militaries,” Pentagon spokesman Col. Steve Warren told reporters on Monday.
“We’ve seen the Russians conduct themselves unprofessionally and in violation of international norms in Ukraine now for several months, and … these continued acts of provocation and unprofessionalism do nothing to help de-escalate the situation in Ukraine, which is what we’ve called on the Russians to do.”

KNIRTI L175M Khibiny-M radar jamming pod
Recently sailors on the USS Donald Cook got owned by Russians:
“Dear Mary, you can not imagine what happened . Such a shame I have ever felt in my life . Some of the children were crying like little kids, our superiors drank half a bottle of whiskey to recover from this stupid Russian Hibiya ( Russian electronic warfare system ) and the master had become green from shame . ”
Russian Khibiny EW suite
The KNIRTI L005S Sorbtsiya-S mid/high band defensive jammer is carried in wingtip pods. Unlike competing Western designs, this system uses a steerable mainlobe to maximise the Jam/Signal ratio at the threat emitter. The design uses a wideband phased array and dielectric lens arrangement (KNIRTI).
Defensive systems in legacy and production Flankers include a Radar Warning Receiver, mostly variants of the SPO-32 / L150 Pastel digital receiver carried. The latest subtypes like the Su-35BM/Su-35-1 carry the KNIRTI L175M Khibiny M Radio Frequency Surveillance (RFS = ESM/RHAW) system, initially developed for the Su-34 Fullback. The Khibiny M is believed to use a channelised receiver and most likely employs a wideband dual baseline interferometer in the forward sector, to permit passive targeting of Kh-31P and R-27P/R-77P variants in defence suppression and air combat roles.
Newer Flankers carry the podded wingtip mounted KNIRTI SPS-171 / L005S Sorbtsiya-S mid/high band defensive jammer (ECM), this system being an evolution of a jammer developed for the Backfire C. The Sorbtsiya-S, unlike most Western jamming pods, is designed to operate in pairs and uses forward and aft looking steerable wideband phased arrays to maximise jamming effect, a similar arrangement to the Eurofighter Typhoon EWSP package. It is worth observing that the Sorbtsiya is clearly built to provide cross-eye jamming modes against monopulse threats, and the wideband mainlobe steering capability provided by the phased array permits best possible utilisation of available jamming power. A graded dielectric lens is employed. Russian contractors have been recently using Digital RF Memory (DRFM) technology, which is of the same generation as the US IDECM EWSP, and competing Israeli systems.
The most recent defensive jamming equipment to be offered on Flanker variants is the new KNIRTI SAP-518 wingtip jamming pod, displayed at MAKS 2009. Concurrently KNIRTI displayed a high power support jamming pod, the SAP-14, intended for centreline carriage on a large pylon. To date little has been disclosed on these pod designs, which are likely to retain the wideband phased array / lens antenna system first used on the Sorbstiya.
