The Indian Air Power has acquired a brand new regiment’s value of S-400 long-range air defence programs from Russia, with native sources reporting on the supply noting that the service is scheduled to obtain a fifth last regiment earlier than the top of the yr, marking a serious milestone in a program meant to revolutionise the nation’s lengthy vary air defence capabilities. 5 regiments’ value of the programs had been ordered underneath a $5.43 billion greenback contract in October 2018, with every regiment is shaped of two battalions, every of which deploys eight missile launchers and supporting radars, command centres and reloading autos. After the S-400 system noticed its first excessive depth fight take a look at outdoors Russia in Could 2025, with its efficiency towards Pakistani forces that month receiving appreciable reward, the Indian Defence Ministry Defence Procurement Council in March 2026 authorised the acquisition of an extra 5 regiments, bringing the full deliberate arsenal to twenty battalions.
Following the disintegration of the Soviet Union, the numerous decline of the Russian fight aviation trade and termination of the MiG 1.42 fifth technology fighter program left the Russian Armed Forces very closely reliant on ground-based programs for air defence, with the Defence Ministry having invested greater than twice as closely in procuring S-400 than it has procuring all fighter varieties mixed over the previous three a long time. Commenting on the S-400’s efficiency, CEO of the Almaz-Antey Group chargeable for creating the system, Yan Novikov, in a December 2025 interview elaboratedon the system’s options and fight document. He noticed: “The parameters of its effectiveness have been confirmed in precise fight, and no international air defence system can rival the S-400 in its class to this point.” “The large modernisation potential of the S-400 air defence missile system, which permits us to shortly mitigate rising threats in the course of the particular navy operation. Owing to this potential, the Triumph has acquired new capabilities and properties which are typically uncharacteristic of air defence programs,” Novikov added.
Notable options of the S-400 system embody its excessive mobility, its excessive 400 kilometre engagement vary, and its means to shoot down very quick targets utilizing missiles with speeds of over Mach 14, which it has used to shoot down U.S.-supplied surface-to-air missiles from the MIM-104 Patriot system within the Ukrainian theatre. The system was developed from the late Nineties particularly to reply to rising challenges from plane and missiles with superior stealth capabilities and lowered radar cross sections, and makes use of a number of varieties of radar working in complementary wavebands to offer excessive ranges of situational consciousness together with towards very low observable targets. Its main sensor, the 91N6 ‘Huge Fowl’ panoramic surveillance radar, has a detection vary of as much as 600 kilometres and may observe tons of of targets concurrently. The newer integration of Nebo-M multi-band 3D radar programs has additional considerably improved situational consciousness for S-400s in Russian service.
The development of recent factories and modernisation of older ones has facilitated a really giant scale of manufacturing of the S-400 in Russia, permitting a number of regiments’ value of the programs to be produced yearly. Essentially the most notable amenities which acquired funding to assist the realisation of a manufacturing surge from the mid-2010s included a brand new wing of the Obukhov Plant in St. Petersburg, the Avitek Plant in Kirov which was throughly modernised, and the NMP Plant in Nizhniy Novgorod. Regardless of the system’s excessive charge of manufacturing, the Russian Armed Forces’ pressing want for extra S-400 battalions within the face of ongoing hostilities with Ukraine and excessive tensions with NATO has resulted in repeated delays to deliberate deliveries to equip Indian forces.
Throughout clashes with Pakistani forces in Could 2025, the Indian S-400s had been credited with having shot down least 5 hostile fighters and one giant plane, which was reportedly both an ELINT or an AEW&C system. The shootdown of the massive excessive worth plane was achieved at a 300 kilometre vary, highlighting the significantly lengthy attain of the S-400’s distinctive 40N6 missiles. Plans to double S-400 procurements have materialised as negotiations have additionally reached superior phases each to rework the capabilities of the Su-30MKI lengthy vary fighter via in depth Russian upgrades, and to acquire Su-57 fifth technology fighters. Russian authorities sources’ affirmation that new purchasers have signed contracts to acquire the Su-57 have fuelled hypothesis {that a} contract for the sale to India could have already been signed.
