US P-8 Poseidon "Submarine Killer" Flying Off Syria Coast

A highly sophisticated US Navy P-8A Poseidon maritime patrol plane, also known as a "submarine killer" was observed by the Strategic Sentinel flying south of Cyprus, having likely departed from Naval Air Station Sigonella in Italy, and headed eastward toward Syria on Tuesday.

The flight comes at a time when not a single commercial plane can be observed over Syria, as per the guidance of Europe's Air traffic control which last night warned that airstrikes on Syria are imminent.

A recent flight path history shows the Poseidon engaged in heavy shore "sniffing" designed to uncover whether any Russian subs are hiding near Syria.

Below we present some more details on the P-8 Poseidon Submarine Killer courtesy of The National Interest.

There is a decent chance you have already flown on one of the U.S. Navy’s key new aircraft—or rather, the 737 airliner it is based on. The P-8A Poseidon maritime patrol plane may not be as sexy as an F-35 stealth fighter, but in some ways it is far closer to the forefront of international flashpoints in the Pacific Ocean. Maritime patrol planes are essential for tracking the movement of ships and especially submarines across vast oceanic waters—and potentially sinking them in the event of hostilities.

Hunting submarines from the air, however, is an airpower-intensive job that requires numerous airframes spending thousands of flight hours flying long-distance patrol patterns over the ocean. Since 1962, the U.S. Navy has operated the P-3 Orion patrol plane, based on the four-engine L-88 Electra airliner. The turboprop-powered aircraft could spend a dozen hours flying low over the ocean to drop sonar buoys, scan the water for metallic hulls of submarines with its Magnetic Anomaly Detector (MAD) and potentially launch torpedoes. After fifty-five years of able service, however, the P-3s have accumulated thousands of service hours and their hulls are growing fatigued.

In 2004 the U.S. Navy selected the jet-powered Boeing P-8 Poseidon to succeed the aging P-3. Development proceeded relatively smoothly, in part due to the use of a preexisting airframe and the decision to phase in the P-8’s advanced systems in a series of increments rather than delivering them all at once. This led the P-8 unit costs to actually come in under budget, at $150 million per aircraft.

The P-8 is based on the 737-800ERX short-to-medium-range airliner. It typically has a flight crew of three and boosts stronger power generators for its onboard electronics. The Poseidon reportedly offers a much smoother ride than the Orion, thanks to its broader-swept wings and flight computers. Orion crews were often nauseated by the strong turbulence their low-altitude flight operations required.

The Poseidon’s primary payload is its diverse array of sensors. These include an APY-10 multi-mode synthetic aperture radar, which not only can track the position of ships over hundreds of miles away, but possesses a high-resolution mode which can spot submarine periscopes poking above the waves and even identify different classes of ships. An MX-20 electro-optical/infrared turret provides a shorter-range search option, while an ALQ-240 Electronic Support Measure (ESM) derived from a system onboard the EA-18G Growler functions as an electromagnetic sensor, particularly useful in tracking the positions of radar emitters.

A recent addition is the Advanced Airborne Sensor, a dual-sided AESA radar that can offer 360-degree scanning on targets on land or coastal areas, and which has potential applications as a jamming or even cyberwarfare platform.

A number of key systems on the P-8 are designed to track submerged submarines. A rotary launcher system in the rear of the P-8 can dispense sonar buoys into the water. A recent upgrade allows P-8s to employ new Multistatic Active Coherent buoys that generate multiple sonar pulses over time, allowing for greater endurance and search range. The P-8 also has its own acoustic sensor, and even a new hydrocarbon sensor that can “sniff” for fuel vapor from submarines.

However, the P-8 lacks the tail-mounted MAD sensor of the P-3 Orion, useful for detecting the metallic hulls of submarines while flying at low altitude. Various reasons have been offered for its removal: the MAD weighed too much at 3,500 pounds, it did not fit with the high-altitude search profile of the P-8, or the new sensors on the P-8 rendered it unnecessary. However, the U.S. Navy is reportedly developing a variant of the an air launched drone, called the High-Altitude Unmanned Targeting Air System, which can carry a MAD sensor and transmit its findings back up to the P-8.

Five operator stations on the port side of the plane carry multifunction displays that can be configured to display whatever sensors and controls are most useful under the circumstances. The P-8’s computers are designed to fuse the data into a single coherent picture for the operators—and can then “push” that data to friendly ships and airplanes. This is a capability the U.S. Air Force has been struggling to integrate into its new E-3G radar planes. The P-3 is also designed to be especially compatible with Navy RQ-4N drones.

In the event of hostilities, the Poseidon can carry five missiles, depth charges or torpedoes in a rotary launcher in the rear hull, and six more on underwing racks. While the P-3 had to fly low to deploy its torpedoes, the P-8 can use a special High Altitude Air Launch Accessory to transform its Mark 54 324-millimeter lightweight torpedoes into GPS-guided glide bombs that can be dropped from altitudes as high as thirty thousand feet. These shed their wings upon hitting the water and hone in on targets using onboard sonar. Poseidons can also carry Harpoon AGM-184H/K antiship missiles with a range of 150 miles.

The Poseidon entered service with the U.S. Navy’s VP-16 squadron at Kadena Air Base on Okinawa in 2013, and around fifty out of a planned 117 are now operational in U.S. service.

The type’s patrol duties have placed it at the forefront of political disputes between the United States, China and Russia.

It was already a long-established and accepted custom for countries to intercept each other’s patrol planes over international airspace. However, this becomes risky when intercepting fighters perform unsafe maneuvers as part of their efforts to intimidate the observation planes. Such antics led to a collision between a Chinese fighter and an EP-3 observation plane in 2002 with fatal results for the Chinese pilot.

On May 9, 2017, a Russian Su-27 fighter buzzed within twenty feet of a Poseidon that was patrolling the Black Sea. The P-8s in turn have practiced chasing Russian submarines. According to the Aviationist, in December 2016 Poseidons were engaged in hunting one or two carrier-hunting Oscar-class submarines in the Mediterranean. Maritime patrol aircraft are one of the few weapon systems that can routinely practice hunting their adversaries under operational conditions—stopping just short of releasing weapons, of course.

If it has oil, if it has gold, if it want to by-pass the US $ or if the unmentionables want it, USA will oblige and attack.


If none of the above, it might do so in any case, if it feels like it, or if it does not like a leader or two.

USA, the world's deadliest, ugliest and most dangerous terrorist state bar none!.

Russian subs have always been excellent. And Americans know that they gamble their entire flotilla by poking the bear. 

But did they get the memo that Russian SAM defenses are also petty good, especially against flying irons like the Poseidon? 

P.s.: I hope trump removed the artwork from his trump tower penthouse...

Yes, maybe it's the illegal Isreali oil dealing with the Kurds, through Turkey?

Israel Is Secretly Buying Oil From Iraqi Kurdistan. Similar Channel Was Used For ISIS Oil


Israel has been secretly buying oil through the Turkish port of Ceyhan, which is supplied by the oil pipeline from Iraqi Kurdistan, the Israeli daily Haaretz reported on April 10.

According to Haaretz, in November Samir Madani, a Kuwaiti oil trader, noticed some oil tankers, heading to the Suez Canal from Turkey’s port of Ceyhan. It stopped somewhere in the eastern Mediterranean outside Israel’s territorial borders, turned off its identification transponder and “resurfaced” a few days later, “mysteriously” lighter than when it had left Ceyhan. Then the vessel sailed to Cyprus and returned to Turkey, loaded up on oil that had come from the northern Iraq and repeated the journey, including the act of disappearing.

LOL... the propaganda mills are convincing everyone that nothing has not been considered and no stone unturned... very convincing on paper... "Wars are good and easy to win" until the whole thing blows up.

Sort of like that insane Teacher in space concept... Looked like a real public relations home run for awhile... until the thing blew up over the centerfield wall.

The Russian submarine fleet is capable of sinking most of the US Navy’s boats in 48 hours.  


They can’t power project by air or sea like we can.  So they focused on missiles and submarines.


But right now American sailors are more at risk from an Israeli missile or torpedo than from Russia or Iran let alone Syria.


If one of these clumsy ass birds did manage to target and launch at a Russian sub it would never land.


Russia is lawfully and morally present in Syria while the US has backed ISIS and Al Qaeda Islamopsychos for reasons having much more to do with Israel than American national interest.   


Putin must by now know that only by making Israel a target will the ‘neocons’ reassess.  


Israel needs to get a very bloody nose if the world has any chance to avoid an ultimately nuclear ww3.

It's been proven the Russians have sailed well within the continental USA and never detected.  

How does anyone know if these bloated money machines even work.   


Id also say their aircraft killer and other ship killers work at a much further range than this thing   

This is flexing without proof that the muscle works.  Trying to scare Russian Chinese and Iranian naval forces.  


All this show of force is really showing desperation.

Ever occur to you that the Israeli missile attack was a test run with the new tech salvo the ones that got through while cheap crap dummies were put up to draw the "super duper" s300/s400 fire?

You think Mother Russia does not have Israeli spies and software in everything it does? You think there are no Israeli spies at Cozy Bear and Kaspersky and IRA and every fucking thing that Russia does? Because Russia pays SO WELL, and all Russians LOVE THEIR LIVES while Vladdies kleptigarchs live like Tsars and they scrape by in tiny shithole apartments and smoke cheap cigarettes like chimneys??

Yeah, I'd love my country too if American billionaires were buying $80 million penthouses in Moscow and trying to launder the entire GNP of the country through Cyprus like Vlad the Embezzler. 

On ZH, Russia=Heaven and US=Hell. That's why there are lines of US supermodels trying to get into Russia. 

Russia makes the most beautiful women in the world, and they all want to get the fuck out of there and go where the good life is, and that AINT ST PETERSBURG. Is that because Russia is soooooo wonderful??

Of course, good Christian Vlad has his concubines, because, after all, what good is it being an autocrat if you don't grab em by the... well, you know.
