Shtil-1 for Indian Navy, fresh memoirs

...A serious test passed "Altair"   when working on ships built for India with   "Kashmir" AA system. Already in Soviet times, under a contract with India, our country started to supply anti-aircraft missile systems of medium-range "Shtil" to the ships of Indian Navy. The complexes were developed by "Altair". Delivery policy documents was carried out separately for different plants, but a prime contractor, responsible for the complex as a whole, was not pointed. In the early 90-ies our equipment was supplied and installed at the Indian ships. Testing began with failures. Missiles did not hit the targets. Who's to blame? Each vendor has starting to prove his innocence.
Then Rosvooruzheniye "addressed to Altair and required          sending a team of specialists headed by chief designer Alexander Sergeyevich Yevstigneyev to deal on the spot. And here revealed the failures of Indian designers on placement of equipment, the choice of general ship radar and other interfaced with SAM "Kashmir" systems. Our     shipbuilders  were not up to par too. It was spoken about inability of our complex to provide the required characteristics.

Evstigneev displayed enviable persistence, presented a compelling argument, proving the opportunity to correct the situation by software change. It was proved the need for an additional contract directly with the institute (Altair) for development a new memory block   with installed new BIOS program and technical documentation on the complex as a whole. The contract was signed. All questions on the Indian ships have been resolved, complex works as expected. "Altair" and the company Rosvooruzheniye "got serious lesson: the responsible part of such complex contract, like anti-aircraft missile system supply, must include its main developer. Further contracts         "Altair" was used to conclude on such conditions.

In 1997, India signed a contract for the construction of three frigates of Project 1135.6 at the Baltic plant with the installation of SAM "Shtil". In order to participate in this very lucrative contracts, the management of the 'Altair'  took the decision to modernize "Shtil" with the introduction of a new computing hardware and new anti-aircraft missiles 9M317E. The complex was named "Shtil-1. Sergey Sokolov Headed the development  . This modernized complex was decided to install on the new Indian ships.

The Work on  "Shtil-1" actually became a turning point in "Altair" modern history, took as a decade. First time in its history the Institute (Altair) took to develop, manufacture, install and test the final product - anti-aircraft missile system in cooperation with others. Director-General SA Klimov  has decided to change the entire structure of the company for this purpose.

Particularly difficult was to address the question of the serial manufacturing. According to the assessment of 'Altair's chief VD Ponomariov the state of 'Altair' serial production capability doesn’t allowed to deliver the complex in time. This was complicated by the fact that the Serpukhov Plant RATEP, the main producer of ship serial air defense missile systems, refused to participate in the manufacture of ZRK "Shtil-1. The newly appointed head of the pilot production VI Kharitonov, together with his deputies FM Shikin and VI Verbitsky have moved aggressively to reorganize and prepare manufacturing line for the new product. 

In an unprecedented short period of time - two years, whole design documentation for the export complex has been reworked, a new mathematical software was developed, hardware was made and carried out the bench tests, which confirmed the readiness for serial manufacturing for product as a whole. Despite vigorous attempts by our detractors to prevent the delivery of complex "Shtil-1" in due time, he was shipped to the shipyard between the first members  , and in March 2002, has successfully completed the   firing tests at a ship Program State tests program. However, the acceptance tests were not impressed.

There is a wonder why this class of complex, which works  well on the domestic ships and ground forces, failed on the Indian frigate. Firstly the suspicion fell on anti-aircraft missiles. But they have checked   the Army's complex in the same series as the ship. The Results were brilliant. A Miniature target was hit by the first missile struck.

Almost six months' work of a special commission allowed to understand all. It turned out that it is not in "Shtil-1", as it tried to prove our detractors, but it's the mistakes made in the whole design of the ship and errors in testing. There was a serious error - one of the ship gun systems worked on the same frequency as the radio equipment missiles. The powerful impact of this gun radar on the rocket when it was in flight, impeded the  missile's work-board, which leads to negative consequences.

But Instead correction mistakes in the design and construction of the vessel, ie create the conditions for the normal functioning of the complex "Calm-1", the leadership of the Baltic plant prefered to solve the problem of electromagnetic compatibility of radio electronic equipment of the new ship via changes in the serial complex "Shtil-1". This position has led to the failure to   transfer   the ship to the customer   in 2002, like it was planned under the terms of the contract. He was handed over to India a year later.

Together with "Amethyst", a developer of naval gun systems, it was managed to find the original technical solutions that reduce the influence of different radio-electronic devices installed on the ship. a number of measures to adapt   the complex Shtil-1 to ship was developed and agreed with the Indian experts

Further shooting tests have showed excellent results and  have confirmed the effectiveness of taken measures, all anti-ship missiles that were used as the target, were shot down. Sent to the customer, three ships of the project 1135.6 "Talwar", "Trishul", "Tabar successfully serving in the naval forces of India.

In the tests of "Shtil-1" SM Sokolov, AM Tomsk, AV Borzunov, EF Glagolev, AV Semigin, NV Alekseev, BS Stavitsky, VP Struchkov, VI Osipenko, VV Danilov actively participated.

Soon after the completion of pr. 1135.6 ships  India has designed its analogue of this project - the frigate "project-17", between the weapons of which   SAM Shtil-1 and EMC (electromagnetic compatibility) equipment "Podzagolovok" were also includes. The signed  contract provided   supply of three sets of these products. Despite some difficulties, the deliveries of "Altair" were performed just in time with consistently high quality. The completion of   project   17 ships and the final testing of weapons by Indian side was to completed in 2008-2009. In 2006, the contract to build three more frigates of Project 1135.6 was signed, it provides the organization of repair companies in India, including the SAM Shtil-1 and EMC hardware "Podzagolovok."

  2. Interesting article on PAKFA

    RIA news in Spanish

    "Russia has the capacity to export more than 600 fifth-generation fighter"

    "... Russian Air Force will acquire at least 400-450 of these aircraft between 2020 and 2040."

    Algeria (possible acquisition of equipment between the years 1924 to 1936 from 2025 to 2030), Argentina (12-24 aircraft between 2035-2040), Brazil (24-36 aircraft from 2030 -2035), Venezuela (24-36 aircraft between 2027-2032), Vietnam (12-24 aircraft between 2030-2035), Egypt (12-24 aircraft from 2040 to 2045).

    Other possible buyers of the fifth-generation Russian fighters are

    Indonesia (6-12 units between the years 2028 to 2032), Iran (1936 to 1948 units between 2035-2040), Kazakhstan (12-24 units between 2025-2035), China (up to 100 units between 2025-2035), Libya (1912 to 1924 units between 2025-2030), Malaysia (12-24 units between 2035-2040) and Syria (1912 to 1924 units between 2025-2030).

  3. Shtil-1 is a very costeffective SAM but its main drawback is its limited by its firecontrol channel and the ability of the FC radar to continuously track and keep a lock at the target till engagement is over.

    Since they have a active radar variant of BUK-M3 under state testing , hopefully we will see that on Shtil-1 and that should take care in some ways over its current limitations.

    Passive AAM systems have better steadiness against jamming. Hopefully they will do some mix between passive and pure active systems.

  5. AFAIK Shtil-1 is a command guidance missile and uses FC Orek radar on ships to guide it to its target.

    What do you mean by Passive AAM , Use of IIR seeker for Shtil-1 system ?

  6. In this case I think he means a missile that is guided to the target by external sources like SARH or radio command guided where the launch platform tracks the target and the missile follows the reflected radar energy (SARH) or is directed by the launch platform (Radio command).
    The reasons being that the size of radar that can be fitted to a SAM is not large and it wont have the power of a ship based radar, nor will it have the processing power or ECCM capability of a large radar. It would be easier to fry the 30cm wide radar in a missile than the enormous powerful radar on a ship.
    The best solution in my opinion is a mix of both SARH and ARH because cost wise it would be cheaper than all ARH, but offer more flexibility than all SARH in the even of a mass attack.

    Because of jamming problem I'm a supporter of combined multi-spectral guiding technique , which has future in my think.

  8. I agree with Igor, having different options makes a lot of sense. A good example would be the old SS-N-2 antiship missile with its old active radar homing. Some models were made with IR seekers and later models had combined IR and radar seekers and I believe India found them effective in a land attack role one time where they were fired at a port where the radar would not be much use with so many targets but the IR seeker locked onto Oil storage tanks that had been heated up by the days sunshine.
    The point is that you never know when such things will come in handy... when operating in an environment where civilian aircraft might operate the option to change target or simply stop illuminating is not really available to active homing missiles.

  9. Hi Igor, It appears that the JV for MRTA was finally signed.. Was there any delays or is this much time taken normal?
