P-8I Neptune: India strengthens the power of anti-submarine aircraft


Indian Navy will significantly increase its capabilities, receiving new naval aircraft aviationcapable of detecting and destroying enemy submarines.


We are talking about an improved multipurpose marine aircraft P8I, which is designed to patrol the entrusted territory, to identify enemy objects under water and take measures to destroy them. The Poseidon P-8 aircraft was developed by the American company Boeing on the basis of the Boeing -737-800ERX airliner for the needs of the US Navy aviation. The first flight of the aircraft was carried out in 2009. At the same time, India announced its desire to purchase a similar aircraft for the needs of its naval aviation.

To meet the needs of the Indian Navy, a special P-8I Neptune model was created, into which some systems developed and manufactured in India were integrated. The main task facing the manufacturer was to adapt the model of the aircraft for operation in the tropical climate of India. The company successfully coped with this task. As a result, the P-8I Neptune became one of the world's best naval patrol aircraft, capable of performing anti-submarine warfare tasks.

Given that India pays special attention to building up its naval capabilities to confront the main rivals in the region - Pakistan and China, the need to create and adopt a special anti-submarine aircraft seemed justified. Moreover, the discovery of submarines is not an easy task, implying the need for a raid of thousands of hours while patrolling a large territory and determining the noise coming from a submarine, against the background of a general increase in noise at sea due to an increase in cargo traffic.

Indian military experts believed that Indian Navy aviation needed a modern and effective alternative to the aging Tu-142 and Il-38 aircraft, which were formerly part of Indian naval aviation. Recall that the Tu-142MK-E in the amount of 8 pieces was adopted by the Indian Navy in 1988. He participated in many military operations, including Operation Cactus in the Maldives and operations on the border with Pakistan, until March 29, 2017, was withdrawn from service. At the same time, Admiral Sunil Lanba, Chief of Staff of the Indian Navy, noted the great contribution of these aircraft to the country's defense capability.

The new P8I patrol aircraft is equipped with modern equipment for searching and tracking submarines and has powerful weapons - harpoon anti-ship missiles, anti-submarine torpedoes Mk.54 and Mk.82 bombs.

Interestingly, an airplane flying at a low altitude and for a long period of time can operate at a higher altitude. It is perfect for patrolling India’s vast coastline of 7516,6 km.

A radar specially designed to work with marine and coastal areas is installed on board the aircraft. Also, the aircraft can carry out ground surveillance. The incoming images have high resolution, in addition, the operator can choose the functions SAR (synthetic aperture radar) and ISAR (synthetic aperture inversion radar). The aircraft also has equipment for detecting thermal signatures.

Exceptional opportunities for the aircraft crew to detect any signals, their classification and identification are provided by the modern EW kit installed on board the aircraft. EW airborne equipment is installed in such a way as to provide full coverage of three to sixty degrees for ESM and other countermeasures, such as jamming of the enemy and cyber response.

The P-8I is capable of launching sonobuys to detect submarines using transceiver systems and hydrophones for listening. Sonobuys transmit signals to an airplane, with one P-8I deploying more than 100 sonobuys as part of a naval patrol operation.

The P-8I can also work with the main aviation group, performing tasks to protect the ship’s group and aircraft carrier from any type of underwater attack. The main goal is to find the enemy submarine before it can launch a torpedo towards the Indian ship.

    P-8I Neptune: India strengthens the power of anti-submarine aircraft
    And to say that in return is impossible. So far, we don’t have anything serial and comparable in characteristics. Unfortunately, but necessary, very necessary. Our coastline is much longer than the Indian

      Boeing P-81 Poseidon
      Boeing P-81 Poseidon (Russian Boeing P-8 Poseidon) is a patrol anti-submarine aircraft developed under the program of a multi-purpose sea aircraft (English multimission maritime aircraft, abbr. MMA) to replace Lockheed P-3 Orion. Designed to detect and destroy enemy submarines in areas of patrol, reconnaissance, participation in anti-ship and rescue operations - both in coastal areas and in the oceans. It is based on the design of the updated Boeing 737-800 airliner, it is distinguished from its ancestor by a wing devoid of winglets, but having wingtips with increased sweep
      Poseidon is notable, first of all, for the most modern solutions in terms of equipment, systems, as well as methods for processing and exchanging information. Its key features include:
      Northrop Grumman AN / ALQ-240 (V1) airborne patrol hardware;
      Smiths Aerospace sighting and navigation system with an open architecture, which allows for the extension of tasks and their flexible reconfiguration;
      Raytheon AN / APS-137D (V) 5 multipurpose radar with an inverted synthesized aperture / synthesized aperture, which allows creating terrain maps, identifying stationary surface targets and (in a special mode) submarines located at periscope depth, fast moving vessels in the coastal zone, also detect aerial targets;
      Raytheon AN / APY-10 electronic intelligence system;
      gyro-stabilized digital optical-electronic station L-3 Wescam MX-20HD on a retractable turret;
      electronic countermeasure system EWSP;
      a digital magnetic anomaly detector that replaces a traditional magnetometer.

    Definitely, if the Indians did not hit them. Base for upgrades, not bad.

    And how can this be translated into the state language of the Russian Federation?

    It is interesting how the Burak-M complex (recognized as unpromising in Soviet times) is capable of deceiving a hundred sonabuys ???

    after 38 years of exploitation in a tropical climate?

    Well, you can only silently envy the Indians. In this direction, something is generally not visible to us. Tu-142 and IL-38 continue to modernize simply no longer makes any sense.

    The whole essence of anti-submarine aircraft is just in the "sonobuy" laughing laughing laughing Modern high-performance sonar buoys can not afford not only Russia but also many NATO countries. One hundred buoys of the R-8 will be pulled on the green lam. I wonder how many buoys will be enough for the defense budget of India, and all? Disposable systems, and in fact any PLO aircraft, are carriers of disposable buoys, which are now too expensive a toy. New solutions are needed.

    I thought how they can, sailor skins will help them, it seems, who believes in what ... I always wonder how many RF submarines go to IO, I know that we can only guess?

    you say sono-buoys, and how much will you take from such a buoy? do not forget about our stub!
