Mission Sudarshan Chakra vs Golden Dome, Iron Dome & Steel Dome

Mission Sudarshan Chakra (MSC) is India's initiative to build an indigenous, layered air and missile defence which is anticipated to happen by 2035. MSC unlike the Israeli Iron Dome will interact as both shield and sword, pairing interception with retaliatory strike. Though it may resemble United States Golden Dome in ambition, Iron Dome in political purpose, and Turkey’s Steel Dome in method, it is in its initial stages and not as expensive as the three.

Key points on MSC

• It is a system of systems, not a weapon. MSC is meant to act like an umbrella within which it will knit together existing command networks (IACCS, Akashteer, Trigun), ballistic missile defence, Project Kusha, medium and short range missiles, guns, lasers and a counter-drone grid.

• Considered to be closest in method to Turkey's Steel Dome. Like the Steel Dome, MSC is to integrate nationally developed layers under one command architecture. Steel Dome is already ahead in terms of development, it began its  deliveries in August 2025 and a $6.5 billion contract has followed in November 2025.

• Closest in ambition to Golden Dome. Similar to US’s Golden Dome, the MSC too aims at a homeland-scale, multi-domain shield and will also focus on surveillance and tracking.

• Not quite like the Iron Dome. Though for shallow level comprehension, the analogy to Iron Dome is often used. But the analogy falls weak because the Iron Dome is a singular short-range counter-rocket system (4 to 70 km) and only the lowest tier of Israel's own multi-layer defence.

• No finalized budget for MSC exists. Unofficial estimates run to approximately ₹1.3 to ₹1.7 lakh crore (about $13 to $18 billion) up front. However, this remains unconfirmed and further developments may be revealed in future.

"Sudarshan Chakra": the name and the system

The Sudarshana Chakra is the discus of Vishnu, also carried by his avatar Krishna. In Sanskrit, the name is  read as "auspicious sight" (su, good, and darshana, sight). In context to the MSC plan, Prime Minister Modi made a reference to the killing of the Sindhu King in Mahabharata, during which Krishna eclipsed the sun  with his Sudarshan chakra, so that Arjuna could keep his vow and kill Jayadratha before the sun dipped into the horizon.

The Prime Minister’s speech came a day before Janmashtami (Birth Anniversary of Krishna). Later, at the Sri Krishna Mutt in Udupi, he framed the mission as an invincible wall of security encompassing critical and important places, tied to the principle of Dharmo rakṣati rakṣitaḥ (those who protect dharma are protected).

What Mission Sudarshan Chakra is

On 15 August 2025, Prime Minister Narendra Modi announced MSC from the Red Fort, New Delhi. The research and development of the system architecture and manufacturing of the components will be done in India on basis of the Atmanirbhar Bharat policy. Sudarshan Chakra is expected to have the capability to execute precise counterstrikes, and incorporate anti-cyber warfare capabilities. In collaboration with the Indian military and private sector businesses, Mission Sudarshan Chakra will entail cooperation between defense research organizations and civilian research laboratories.

Sudarshan Chakra architecture will encompass the Integrated Air Command and Control System, the Trigun system, and the Akashteer network into a unified, multi-layered air defense grid.

According to General Anil Chauhan, the multi-domain intelligence, surveillance, reconnaissance, and the integration of sensors placed on land, in the air, on ships, underwater, and in space will be crucial. The project will require building infrastructure and procedures for the detection, acquisition, and neutralization of the enemy’s threats.

On 28 November 2025, Defense Secretary, Rajesh Kumar Singh, announced that MSC groundwork had commenced. A combination of Make in India, imports, and IDDM (Indigenously Designed, Developed, and Manufactured) initiatives will be utilized to execute the project. According to reports, a comprehensive project study and feasibility plan will be prepared by a team under DRDO and Air Marshal Ashutosh Dixit. Defence capital expenditures will be also utilized to finance the entire project. Integrated air defense systems and counter-UAS grids are being developed by the Indian military.

Mandate and governance

• Lead agency:The legal agency is DRDO. Defence Minister Rajnath Singh said on 1 January 2026, that DRDO is responsible for equipping vital installations with air defence over the next decade.
• Phasing: on 16 September 2025, Singh said a committee would draft an action plan, with a medium-term plan to 2030 and a long-term plan to 2035.
• Funding route and sourcing: the Defence Secretary said on 28 November 2025 that groundwork for MSC had commenced and was to be paid from defence capital expenditure and delivered through a blend of Make in India, imports and IDDM (indigenously designed, developed and manufactured) projects.
• Stated goals: subsystems fully developed and produced in India, predictive technologies to anticipate future warfare and accurate systems able to retaliate quickly.
• Three layers: on 12 June 2026, at DRDL Hyderabad, Singh described MSC as a multi-layer missile defence providing three layers of protection and urged DRDO to move faster from development to production.

Architecture: what is being stitched together

The table lists the building blocks reported so far.

A tested integrated core already exists. On 23 August 2025 DRDO fired QRSAM, an advanced VSHORADS and a laser at two fixed-wing drones and a multicopter in one engagement under a common command center.

The development so far

The components are moving faster than the umbrella programme around them.

• Paperwork: the Defence Secretary said on 30 April 2026 that a team under the DRDO chairman had submitted a pre-feasibility report. An idrw report stated that the DRDO chief Samir Kamat detailed a completed feasibility report heading to the Defence Minister, with Phase 1 deployment possible within two to three years.
• Hardware tests: the integrated air defence weapon system (23 August 2025), BMD interceptors AD-1 and AD-2 (10 and 11 June 2026, from Chandipur) and Kusha M1 (23 July 2026, against an electronic target) have all flown. Kusha M2 and M3 trials are reported for 2027 and 2028.
• Command networks: on 27 March 2026 the Defence Acquisition Council cleared an Air Defence Tracked System to give real-time air defence control and reporting.
• S-400: the same DAC meeting gave Acceptance of Necessity to further S-400 systems within a ₹2.38 lakh crore package. The fifth squadron under the original $5.43 billion contract is due in November 2026. That outlet itself warns that approval and a Russian proposal are not a signed contract.
• Scale of the long-range pipeline: idrw reports a medium-term pipeline of 15 long-range squadrons (ten S-400 and five Kusha), with up to 23 possibly needed for overlapping cover.
• Timeline: Air Chief Marshal A.P. Singh has stated, the IAF aims to fully deploy Phase 1 by 2028 to 2029. The Defence Forces Vision 2047 document of 12 March 2026 also called for expanded ballistic missile and air defence.

Budget: There is no MSC cost published by the government. A Financial Express estimate cited puts initial spending at ₹1.3 to ₹1.7 lakh crore (about $13 to $18 billion), plus about ₹25,000 crore a year to run. For scale, the FY2025-26 defence budget was ₹6.21 lakh crore.

The comparison systems, by the numbers

Iron Dome (Israel)

• Origin: built by Rafael and Israel Aerospace Industries. Its development began in 2007 and the first units were deployed in 2011. It was declared operational on 27 March 2011 near Beersheba, and its first combat interception followed in April 2011.
• Role: it engages rockets and artillery shells from 4 to 70 km, and ignores projectiles that will not hit a populated area. A launcher holds up to 20 Tamir interceptors.
• Place in Israel's stack: it is the lowest layer. David's Sling covers medium-to-long-range rockets and cruise missiles, and Arrow 2 and Arrow 3 cover ballistic missiles in and above the atmosphere.
• Cost: a battery is commonly put at about $50 million. Tamir is often cited at $40,000 to $50,000, though a US Army budget line reportedly listed about $163,000, and various reports give $100,000 to $150,000 per interception. The US had spent over $2.9 billion on the program as per the Congressional Research Service
• Performance claims: Israeli forces reported above 85% interception in 2014 and 90% in 2021.

Golden Dome (United States)

• Origin: a January 2025 executive order titled "The Iron Dome for America" set the goal. The design was announced on 20 May 2025 with a $175 billion price and a three-year target. Space Force Gen Michael Guetlein runs the program.
• Role: homeland defence against ballistic, hypersonic and cruise missiles, with sensors and interceptors across land, sea and space. The order specifically required space-based interceptors.
• Cost, four numbers: Guetlein put the objective architecture at $185 billion out to about 2035, and the administration plans about $79 billion in the program’s own account over five years. The Congressional Budget Office's May 2026 illustrative estimate was $1.2 trillion over 20 years. The American Enterprise Institute's Todd Harrison estimated about $1 trillion for a specific architecture in 2025 (same article), and AEI has put a robust architecture including operations at about $3.6 trillion (Federal News Network). Guetlein has dismissed outside estimates as not pricing what he is building.
• Cost driver: about $730 billion of CBO's total goes to space-based interceptors, enough to destroy only about 10 incoming ballistic missiles (Defense One); the Atlantic Council puts their share nearer 70%. Without them CBO's total falls to $448 billion, but that system would not meet the executive order. Guetlein has said boost-phase interceptors will not go into production if they cannot be made affordable. In April 2026 the Pentagon awarded $3.2 billion to twelve companies for interceptor concepts and demonstrations (Atlantic Council).

Steel Dome (Turkey)

• Origin: approved on 6 August 2024 and unveiled by Aselsan's CEO the next day. On 27 August 2025 Erdogan marked the delivery of 47 vehicles worth $460 million.
• Role: a four-layer, network-centric system (very short, short, medium and long range) built by Aselsan, Roketsan and TÜBİTAK SAGE. It includes the Korkut guns, Hisar and Siper missiles and the AI-enabled Hakim command system. Siper is reported at 100 to 150 km.
• Money: on 26 November 2025 Türkiye signed a $6.5 billion contract with Aselsan, Havelsan and Roketsan. Aselsan's CEO said in May 2026 that it is evolving into a broader nationwide architecture.
• A useful caution: one Turkish academic called it less a new system than an effort to integrate air and missile defenses developed over the past decade, and said the Russian S-400 is outside it . The same description fits MSC.

Similarities and differences

MSC overlaps most with Steel Dome on method and with Golden Dome on scope and its stated offensive role has no counterpart in the other three.

Conclusion

Mission Sudarshan Chakra is India's version of the dome idea, but quite similar to  the Turkish way: integrate what exists, finish what is in test, and add a command layer. It shares same scope as the US Golden Dome's scale of ambition without its space-interceptor bill, and Iron Dome's purpose without its narrow technical scope. Its credibility will rest less on the 2035 slogan than on whether the 2026 to 2030 milestones (Kusha, the counter-drone grid, the linked command networks) arrive on schedule and under a published budget.
