S-400 missile system

The S-400 Triumf (C-400 Триумф, Triumph; NATO reporting name: SA-21 Growler), previously known as the S-300PMU-3, is an anti-aircraft weapon system developed in the 1990s by Russia's Almaz Central Design Bureau as an upgrade of the S-300 family. It has been in service with the Russian Armed Forces since 2007. The S-400 uses four missiles to fill its performance envelope: the very-long-range 40N6 (400 km), the long-range 48N6 (250 km), the medium-range 9M96E2 (120 km) and the short-range 9M96E (40 km). The S-400 has been described, as of 2017, as "one of the best air-defence systems currently made."

Development
Development of the S-400 system began in the late 1980s, and the system was announced by the Russian Air Force in January 1993. On 12 February 1999 the first, reportedly-successful tests were performed at Kapustin Yar in Astrakhan, and the S-400 was scheduled for deployment by the Russian army in 2001.

In 2003, it became apparent that the system was not ready for deployment. In August, two high-ranking military officials expressed concern that the S-400 was being tested with "obsolete" interceptors from the S-300P system and concluded that it was not ready for deployment. Completion of the project was announced in February 2004, and in April a ballistic missile was successfully intercepted in a test of the upgraded 48N6DM missile. In 2007, the system was approved for service.

Structure
The 30K6E is an administration system which manages eight divisions (battalions). The 55K6E is a command and control centre based on the Ural-532301. The 91N6E is a panoramic radar detection system (range 600 km) with protection against jamming which is mounted on an MZKT-7930. The S band system can track 300 targets. Six battalions of 98ZH6E surface-to-air missile systems (an independent combat system) can track no more than six targets on their own, with an additional two battalions if they are within a 40 km range. The 92N6E (or 92N2E) is a multi-functional radar with a 400 km range which can track 100 targets. The 5P85TE2 launcher and the 5P85SE2 on a trailer (up to 12 launchers) are used for launch. The 48N6E, 48N6E2, 48N6E3, 48N6DM, 9M96E, 9M96E2 and the ultra-long-range 40N6E are authorised by a Russian presidential decree. According to the Russian government, the S-400 utilises an active electronically scanned array.

Optional elements of the S-400 (98ZH6E) include the 15I6ME–98ZH6E, with coverage of 30, 60 and 90 km beyond the 30K6E coverage. The 96L6E has a 300 km detection range. The 40B6M is housing for the 92N6E or 96L6E radar. The Protivnik-GE is an anti-stealth UHF radar with a 400 km range. The Moscow-1 passive sensor is $2 1/2$ times more effective than the Protivnik, with a 400 km range Orion for a target-designation on-the-air defence system, and the Avtobaza-M and Orion+ Avtobaza adds high-precision detection. The 1RL220BE versions were reportedly were used for jamming. The 400 km-range S-200D Dubna (SA-5c) missiles and S-300 P-family radar systems can be used without additional command-and-control centres. S-300 (SA-20A, SA-20B) missiles may also be guided. A-50 and A-50U aircraft provide early warning and command-and-control target designation.

The 30К6Е control system can be integrated with the S-400 Triumph 98ZH6E system; the S-300PMU2 (through the 83М6Е2 control system); the S-300PMU1 (through the 83М6Е control system); the Tor-M1 through the Ranzhir-M battery-command post; the Pantsir-S1 through the lead battery vehicle. The Protivnik-GE and Gamma-DE radars, integrated with the 92H6E radar system, enables communication between each battery with Baikal-E senior command posts and similar types; nearby 30К6Е, 83М6Е and 83М6Е2 administration systems; the Polyana-D4М1 command post; fighter-aircraft command post, and mobile long-range radars. The Nebo-M system is designed to hunt the F-35 joint-strike fighter. The system's VHF component provides sector search and tracking, with the X- and L-band components providing fine-tracking capability. Good placement of the radars relative to the threat axis enables the L- and X-band components to illuminate the incoming target from angles where the target RCS is sub-optimal. Attempts to jam the Nebo-M would be problematic, since all the radars have passive angle track capability against jammers; jamming permits passive triangulation of the target using three angle-track outputs. The RLM-S and RLM-D have better elevation-tracking accuracy than the RLM-M, and the Nebo M should be capable of producing high-quality tracks suitable for mid-course guidance of modern surface-to-air missiles and trajectory guidance of legacy SAMs.

The Gamma-C1E SHF mobile radar station has a 300 km detection range. The Nebo VHF mobile radar station and the Resonance-NE radar station have a detection range of 1200 km and 65 km to a height of 500 m. All Nebo-family locators are doubled for army air defence. During the 1970s, the long-range mobile UHF 5H87 and SHF 5H69 low-altitude locators were used. a 1980s goal was detection at a height of 10 m at a distance of 40 km.

For export to foreign customers, with the purpose of integrating existing customer air defence systems, additional work on improvement of the 30K6E administration system for information technology pairing with anti-kets is in progress.

Missiles
One system comprising up to 8 divisions (battalions) can control up to 72 launchers, with a maximum of 384 missiles (including missiles with a range of less than 250 km). The missiles are fired by a gas system from the launch tubes up to 30 metres into the air before the rocket motor ignites, which increases the maximum and decreases the minimum ranges. In April 2015, a successful test firing of the missile was conducted at an airborne target at a range of 400 km; TELs carrying the long-range 40N6 may only be able to hold two missiles instead of the typical four due to its larger size. Another test recorded a 9M96 missile using an active radar homing head, reached a height of 56 km. All the missiles are equipped with directed explosion warhead, which increases the probability of complete destruction of targets. In 2016, Russian anti-aircraft missile troops received new guided missiles for S-300 and S-400 defense systems. Anti-aircraft missile system, designed to destroy aircraft, cruise and ballistic missiles, it can also be used against ground objectives. The S-400 is able to intercept cruise missiles out to a range of about 40 km due to their low altitude flight paths.


 * The ABM capabilities of the S-400 system are near the maximum allowed under the (now void) Anti-Ballistic Missile Treaty.
 * The new anti-ballistic missiles 77N6-N and 77N6-N1 to enter service in 2014 supposedly add inert/kinetic anti-ballistic capability to the system. The same missiles will also be used by the S-500, which has a clearly stated anti-ICBM role.

Morpheus defence system

 * A separate independent air defence system 42S6 Morfey (Morpheus) is being developed. This system is designated as short-range air defence system to protect the S-400 from various threats at their terminal phases, and will also act together with the S-350E as a supplement to the SA-21 Growler. Together, these systems form part of the Aerospace Defence Forces.
 * Development of Morfey started in 2007 and was planned to be introduced in 2013, however was delayed until at least 2015.  The missile system consists of omnidirectional 29YA6 radar, infrared sensors and 36 missiles. The missiles have up to 10 km range and an altitude of up to 3500 m.

Deployment
A regular S-400 battalion consists of at least eight launchers with 32 missiles and a mobile command post. On May 21, 2007 the Russian Air Force announced that S-400 would be put on combat duty around Moscow and Central Russia by July 1, 2007. The S-400 was also deployed near the town of Elektrostal.

On August 6, 2007, the first regiment equipped with S-400 entered active service in Moscow Oblast near Elektrostal, according to Channel One Russia. This is the 606th Guards Anti-air Rocket Regiment, 9th PVO Division, 1st PVO Corps, of the Special Purpose Command.

On February 8, 2008, Lt. Gen. Vladimir Sviridov announced that Russia will be replacing the S-300 systems in the Northwest of Russia with the more technologically advanced S-400. Russian military experts expect that Russia plans for this system to be in place and represent a major component of their ballistic missile defense system until 2020.

In September 2006, Deputy Prime Minister Sergei Ivanov announced a new state program of armaments for 2007–2015. This program provides for the purchase of 18 missile battalions of S-400s.

On March 17, 2009, Russia's defense minister announced that a second regiment equipped with advanced S-400 Triumf air defense missile systems has been put into combat service.

On August 26, 2009, the General Staff said S-400 systems had been deployed in the Russian Far East to counter possible North Korean missile tests and prevent fragments from falling on Russian territory.

In February 2011, a second unit of S-400 missile systems was deployed at Dubrovki, north of Moscow. The 210th Air Defence Regiment consists of two battalions, each consisting of eight launch points, each with four missiles. In February 2011, it was also announced that the missile system will be deployed in southern Kuril Islands "to protect Russia's sovereignty in the Far East".

The Baltic Fleet in Kaliningrad received S-400 SAM systems in February 2012, and these went into operational status in April 2012. One S-400 division is deployed on combat duty in the Russian far east city Nakhodka.

As of 2012, one system (in Electrostal) was operational, with three more S-400 battalions being deployed. All 56 battalions will be delivered by 2020. Russia is also setting up two regiments of S-400 in Eastern Military district.

As of September 2013, the Russian Armed Forces had five S-400 regiments: two in Moscow, one in the Pacific fleet, one in the Baltic Fleet, and one in the Southern Military District. From 2014, the army was to receive two to three sets of regimental units of S-400 systems every year. Another S-400 regiment was to be put on combat duty around Moscow by the end of 2013. Russia plans to have 28 S-400 regiments by 2020, each comprising two or three battalions with four systems each, mainly in maritime and border areas.

In November 2015, it was announced that when the Kirov-class battlecruiser Admiral Nakhimov was recommissioned with the Russian Navy in 2018, it will be equipped with the 48N6DMK anti-aircraft missile derived from the land-based S-400. The inclusion of the 48N6DMK into the Kirov's arsenal extends its air defense range from 100 km with the 48N6E2 missile from the S-300FM to 250 km.

On 1 March 2016, acting commander of the 14th Air Force and Air Defense Army major-general Vladimir Korytkov said that six S-400 units had been activated pursuant to his order in the anti-aircraft missile regiment of the Novosibirsk air defense formation in Russia’s Novosibirsk region. TASS also reported that as of the end of 2015, a total of eleven Russian missile regiments were armed with S-400, and by the end of 2016 their number was expected increase to sixteen.

Syria
In November 2015, the deployment of S-400 was reported in Syria, along with the contingent of Russian troops and other military hardware in the course of the air campaign conducted by the Russian forces on the side of the Syrian government. However, those reports were refuted by Russia. On 25 November 2015, the Russian government announced it would deploy S-400 in Syria in response of the downing of its SU-24 jet by Turkey. On 26 November 2015, such deployment was reported by official Russian news media to have been carried out. The first S-400 system was reportedly installed at Humaymim Air Base in Latakia province.

Between April and July 2017, a second S-400 system was deployed 13 km northwest of Masyaf, Hama Governorate.

Foreign interest
On 23 August 2007, RIA Novosti reported that their sources indicated that Russia would not export the S-400 for the next few years.

During the 2009 International Defence Industry Fair in Istanbul, interest was expressed by Turkey in buying the system.

Vice Chairman of Russia's State Duma Vladimir Zhirinovsky has urged the fast delivery of the S-400 anti-aircraft missile systems to Iran.

On 24 August 2009, RIA Novosti reported that their sources indicated that Belarus had submitted a formal request for two battalions of S-400 systems.

In September 2009, it was reported that the S-400 system is part of a $US2 billion arms deal being negotiated between Russia and Saudi Arabia. As of March 2010, this was still under negotiation. The Saudis want to buy twelve systems, each of eight launchers. The Saudis were trying to buy the more modern S-400, but the Russians reportedly only wanted to sell the older S-300.

South Korea is developing a simplified version of the S-400 called M-SAM Cheolmae-2 with the help of Almaz (Russian). The prime contractor is Samsung Thales, a joint venture between Samsung and Thales (French). The M-SAM will be composed of an X band multi-function radar vehicle built by Samsung Thales in technical cooperation with Almaz, and fire-control vehicles and transporter erector launchers built by Doosan. LIG Nex1 will provide the missiles.

In February 2017, Sergey Chemezov, CEO of Rostec Corporation, stated that Egypt was interested in the S-400 system. He explained that Russia offered Egypt to purchase either additional Antey-2500 systems or the S-400 system which was much more expensive. Chemezov noted that Cairo had financial issues which delayed the negotiations.

China
In March 2014, it was announced that Russian President Vladimir Putin gave authorization to sell the S-400 system to the People's Republic of China. If China should acquire the S-400, reported to initially consist of six batteries, it would significantly improve China's ability to defend its own air space and serve as an effective stand-off weapon against air attacks. With a 400 km coverage range, aircraft in disputed areas off the coast could be targeted by SAMs from the mainland; all of Taiwan would be covered from Fujian Province, and the Diaoyu Islands would be covered from Shandong Province, making it difficult for the US and Japan to deploy combat aircraft over those airspaces. Taiwan seeks to address these potential advantages by locating S-400 batteries once activated using extensive SIGINT units and destroying them with stand-off weapons, cruise and ballistic missiles, and anti-radiation missiles.

On 13 April 2015, the chief executive of the Russian state-run arms trader Rosoboronexport has confirmed that China secured a contract with his company for the purchase of the S-400 air defence systems.

Although China's acquisition of the S-400 system has been viewed as a "game changer" in the region, several factors may constrain its effectiveness in East Asia. Though the 40N6 missile has a range of 400 km, it is not known if such a missile is available for export. Even if China does acquire the missile, the disputed Diaoyu Islands would be at the limit of its range if stationed along the coast, as would the Indian capital New Delhi if stationed right on the border and moved into the Himalaya Mountains. Against Taiwan, only the 40N6 could bring all its airspace in range, but deploying it along the coast of Fujian Province at sea level would prevent it from locating low-level aircraft at long range due to the Earth's curvature; the shorter-range 48N6 would be even less useful against maneuvering targets at long range. These issues, along with dangers of misidentifying and engaging friendly aircraft at such great distances, may restrict Chinese S-400 use to mainly defensive purposes.

India
In Oct 2015, it was reported that India's Defence Acquisition Council would acquire 12 units of S-400 for its defence needs. However, on 17 December 2015 it was confirmed that the final order will be for five units rather than 12 units as it is considered to be adequate for India's defensive needs. The deal is worth US$ 5 billion.

On 15 October 2016, on the sidelines of BRICS Summit, India and Russia signed an Inter-governmental Agreement (IGA) for the supply of five S-400 anti-aircraft missile systems and the final discussion of terms of the contract is underway as of 2 June 2017.
