Golden Dome, Iron Dome, Steel Dome: Comparative Report

Executive summary

The three "domes" mentioned in the report are not comparable systems. The Israeli Iron Dome is a  short-range interceptor, Steel Dome is a Turkish national architecture now in delivery, while the Golden Dome is a US homeland initiative which remains a subject of ongoing debate regarding its architectural design, complete budget, and technical feasibility.

• Iron Dome (Israel)

Based on records, only Iron Dome has a substantial combat record. The 2026 Iran war has displayed that the layered system, not Iron Dome alone, carries the load, with interceptor stocks as the limit.

• Golden Dome (US)

The projected cost of the U.S. Golden Dome missile defense program spans a massive range, from $175 billion to $185 billion estimated by the White House and Pentagon, to $1.2 trillion over 20 years projected by the nonpartisan Congressional Budget Office (CBO), with some independent and congressional analyses warning costs could reach between $3.6 trillion and $6.2 trillion.

• Steel Dome (Türkiye)

The system links domestic radars, electronic warfare, guns, lasers and Hisar and Siper missiles under AI-assisted command. Erdoğan announced $24 billion in July 2026. The first integrated field exercise was in May 2026, with live intercepts unconfirmed at the moment.

Global Implications & Strategic Stability

Production Bottlenecks: The manufacturing capacity of Interceptors is the binding constraint globally, this raises the importance of affordable layers against drones and cruise missiles over primary interceptors.

Geopolitical Strain: The Golden Dome has created some complex issues with regards to strategic stability with Russia and China, turning allied participation into a bargaining chip for trade and territorial concessions.

Regional Dynamics (India & Pakistan)

India's framework is similar to the Steel Dome model rather than the Iron or Golden Dome. Rafael’s proposed Tamir production line links India directly to Iron Dome technology. Pakistan's increasingly dense, layered defense network demands ongoing evaluation.

Caveat: it is imperative to mention that the performance and cost data are primarily supplied by the developing or deploying parties; conflicting metrics are outlined in the contested-claims section.

Iron Dome (Israel)

Iron Dome is Israel's short-range counter-rocket, artillery, mortar and drone interceptor and the lowest tier of its layered defence. It is the only one of the three systems with a long combat record, and the model the other two are measured against.

Iron Dome is developed by Rafael Advanced Defense Systems with IAI's Elta radar and the IDF. It was selected as Israel's response to short-range rockets in February 2007. A battery combines a radar, a battle-management center and launchers firing Tamir interceptors. It fires only at projectiles predicted to hit populated or sensitive areas, which is the source of its cost efficiency.

Iron Dome sits below David's Sling (medium range), Arrow 2/3 (long-range and exo-atmospheric ballistic defence) and the Iron Beam laser. Based on several reports, Iron Beam was used operationally for the first time against Hezbollah rockets in March 2026.

Per-interception figures vary widely by source with regards to cost: approximately $30,000, about $50,000 in Israeli media reports, and $100,000-150,000 in other estimates are reported. Higher-tier interceptors can be placed above $2 million each. A battery is put at roughly $50 million.

Combat record

• Rafael chairman Yuval Steinitz stated in May 2026 that the system achieved around 98-99% against Hamas and Hezbollah rockets since October 2023. Other outlets cite 90% or more.
• In the 2026 during Iran war the relevant figure is for the whole layered system, not Iron Dome alone. The IDF reportedly claimed about 92% for ballistic missiles as of 27 March, with 9 single-warhead hits and 30 cluster-warhead hits.
• In the June 2025 the IDF said 80-90% across the layered network, including allied assets.

United States link

The US bought two batteries in 2019. Raytheon and Rafael's R2S joint venture in Camden, Arkansas has delivered the first Tamir interceptor entirely built in the US. The Marine Corps' MRIC programme uses the Tamir (marketed as SkyHunter) with American radar and command-and-control, planned at 44 launchers and 1,840 interceptors.

Golden Dome (United States)

Golden Dome is a US homeland missile-defence programme, not a single system. It is still in development, its public architecture is thin, and its cost and scope are the most contested of the three.

Origin and mandate. A January 2025 executive order (first styled "Iron Dome for America") called for a reference architecture against missile threats "from peer, near-peer, and rogue adversaries". Trump announced a $175 billion plan in May 2025 and stated it would be finished within his term. Space Force Gen. Michael Guetlein runs it as a direct-reporting program manager.

As reported by the Pentagon

Guetlein stated on 17 September that the priority is defence against "a coercive decapitation or rogue nation attack", not a shield against Russia or China's full arsenals. He described two stages:

1. By 2028: integrate existing sensors, interceptors and command systems against decapitation and rogue-state attacks.
2. By 2035: add next-generation technology, including directed energy, new communications and sensing, and quantum.

The architecture spans space-based sensors (including HBTSS tracking satellites), ground-based interceptors (CBO's costed design builds on GMD, Aegis Ashore and THAAD; the Pentagon has not published its own list), and a command-and-control layer Guetlein calls "secret sauce", built by a consortium with Lockheed Martin, RTX and Northrop Grumman as primes.

Space-based interceptors (SBI)

Guetlein calls SBI the highest-risk element, "an economics, scalability problem" rather than physics. Twelve contractors cleared the first gate of a four-milestone prize competition in August, with flight tests due from 2027 and about $3.2 billion in prizes. Full production contracts follow only if the directorate judges SBI feasible.

Cost: two incompatible numbers

• Pentagon: $185 billion for the "objective architecture" through about 2035, up $10 billion in March to accelerate space capabilities.
• CBO (May 2026): $1.2 trillion over 20 years for a system that fully implements the executive order, including a 7,800-satellite SBI constellation costing $743 billion to counter a raid of 10 ICBMs.
• Guetlein says CBO is not estimating what he is building. AEI's Todd Harrison reads the $185 billion as implying SBI will be a minor part of the architecture, if it leaves demonstration at all.

Funding and politics

Congress provided $24 billion for missile defence in the July 2025 reconciliation act, including $5.6 billion for SBI. The FY2027 request adds $18 billion via reconciliation plus $68 billion in the regular budget, but Senate Majority Leader Thune has signaled another reconciliation bill is unlikely before the November midterms. At a late-September Senate hearing, Sen. Angus King said nationwide coverage was "not in the cards" and questioned as to who is protected and who is not.

Organization (October 2026)

JTF-Gold under NORTHCOM now also holds the cyber-defence mission. Officials have not settled which assets fall under it, and a planning sprint is set for late October. SpaceX's reported defence obligations reached $5.9 billion in FY2026 to date, up from $1.8 billion in all of FY2025.

Steel Dome (Turkey)

Steel Dome (Çelik Kubbe) is Turkey’s national layered air and missile defence architecture. It is a network of domestic radars, electronic-warfare systems, guns, lasers and missiles under one AI-assisted command layer, and is already being delivered to the armed forces.

Origin. The program was approved by the Defence Industry Executive Committee on 6 August 2024. after circulating internally as "Gökkubbe". It is framed as an architecture connecting existing and future systems, not a new weapon. Aselsan integrates and leads; Roketsan, Havelsan, Tübitak Sage and MKE supply missiles, software, guidance and munitions. The head of the procurement agency, Haluk Görgün, cited hundreds of subcontractors, many of them small and medium firms.

Layers ( publicly reported).

Sources for the table: Warsight and Quwa. At SAHA 2026 the procurement agency announced contracts for Siper-A and Siper-4 ballistic-missile-defence layers; their performance has not been published.

Status.

• 27 August 2025: first major delivery, 47 vehicles worth about $460 million, including one Siper battery and three Hisar-O+ batteries.
• January 2026: Siper Block 1 entered service after acceptance testing that included discriminating friendly from hostile tracks.
• 20-21 May 2026: first integrated field deployment at exercise EFES. Quwa notes it is not confirmed that any layer made live intercepts, as opposed to coordinated tracking and cueing.
• Aselsan's CEO has set a target of more than 100 system-component deliveries in 2026. The $1.5 billion Oğulbey production base is meant to more than double capacity.

According to what is known, there is no single Steel Dome contract. The procurement agency reportedly signs piece by piece. Reported figures include $6.5 billion in contracts in November 2025, a €780 million (about $900 million) Aselsan deal in June 2026, and a €1.47 billion production contract in July. At the July 2026 NATO summit in Ankara, Erdoğan said Turkey had allocated an additional $24 billion. NATO also signed a $26.3 billion air and missile defence framework there. Its contents, including any Steel Dome interoperability or technology transfer, have not been published as of yet or known.

Strategic logic. Turkish officials have cited  the Ukraine-Russia and Israel-Iran war as examples and analysts quoted by Breaking Defense link the architecture to hardening Turkey’s position, including deployments on Cyprus. The stated aim is also industrial, it is to make Turkey a net exporter of air defence.

Side-by-side comparison

Iron Dome is a proven weapon system, Steel Dome is an architecture of systems now being delivered, and Golden Dome is a program whose objective architecture is not public. Comparing them one-to-one overstates how alike they are.

Countries and their positions

Israel, the United States and Turkey own the three systems. A wider set of states has either joined, bought into or copied the "dome" model, and the two largest nuclear rivals of the US have condemned it.

Two threads cut across the table. First, the Gulf war made interceptor supply the binding constraint for every Patriot and THAAD user, which is why Tamir and Siper production lines are suddenly strategic assets. Second, Golden Dome participation is being negotiated alongside trade, territory and burden-sharing, not on technical merit alone: Canada's price tag, Japan's reported use of it as a bargaining chip in trade talks, and Greenland.

Strategic implications for other nations

1. "Dome" now covers three different strategic logics. Iron Dome is tactical cost-exchange defence of populated areas. Steel Dome is sovereign integration and industrial scale-up of ground-based air defence. Golden Dome is strategic homeland defence with a space layer. Taiwan, India and Europe's Sky Shield borrow the label but face different threat sets and budgets, so the transferable lessons differ by case. Assessment: the branding is doing political work (deterrence signalling, budget advocacy) as much as describing architecture.
2. Interceptor depth, not technology, fails first.

Al Jazeera reported that Iran imposes costs by keeping air defences on constant alert and depleting stocks, and the Gulf data above bears that out. The response is evident in the industrial moves: Rafael-Raytheon's Arkansas line, Rafael's India talks, Japan's expected request to produce missiles for the US, and Turkey’s $1.5 billion Oğulbey base. The states without domestic interceptor production will face a supplier-dependence problem that outlasts any particular war.

3. Cheap layers matter more than the headline interceptor. Steel Dome's guns with programmable airburst ammunition, lasers, microwave weapons and electronic warfare, and India's IADWS laser, are aimed at the drone and cruise-missile volume that makes missile-for-missile defence unaffordable. The Iron Dome precedent supports this. Its economics depend on engaging selectively, and the layer above it costs more than $2 million per missile.
4. Strategic stability is the live cost of Golden Dome. Beijing and Moscow's May 2026 statement calls the program an "obvious threat to strategic stability" and ties it to the lapse of New START. Counter-arguments also exist. CSIS has highlighted both views, and Guetlein's stated priority of decapitation and rogue-state attacks is narrower than the executive-order language the Sino-Russian statement quotes. The gap between the classified architecture and the executive-order text lets adversaries plan against the broader reading, which can present to be far more dangerous for third countries sitting between nuclear powers.
5. Alliance bargaining is attached to the technology. Canada's price, Japan's trade leverage and Greenland all show Golden Dome being negotiated as part of wider US bargaining. Turkey shows the opposite pattern. A NATO member building a sovereign architecture while also signing a NATO air and missile defence framework, with contents unpublished.
6. Regional blocs may become channels for air-defence technology. Saudi Arabia, Turkey and Pakistan signed the Mecca Joint Defence Agreement on 7 August 2026, an attack on one is attack on all pact, and their defence ministry statements stress joint production and technology exchange.

India

Mission Sudarshan Chakra, announced 15 August 2025 with a 2035 target, is an umbrella for existing assets (S-400, Akash, Barak-8, Akashteer/IACCS) and new ones: DRDO's IADWS (QRSAM, VSHORADS and a 30 kW laser, first tested 23 August 2025) and Project Kusha, whose three long-range SAMs are due by 2028 with induction from 2030.

Comparisons that fit

• Steel Dome is the closer analogue than Iron Dome or Golden Dome. Both are sovereign, layered, networked architectures built largely from existing and near-term systems under one command layer. The difference visible from outside is procurement tempo: Turkey has published delivery ceremonies and contract values piece by piece, while India's contracting is far less visible. Steel Dome's integrated performance is still unproven, so it is a model for structure, not yet for results.
• Iron Dome is a component lesson, not a template. Swarajya magazine argues India faces nuclear-armed adversaries, hypersonics and a subcontinent-scale battlefield that Iron Dome never had to address. The relevant import is the Tamir interceptor. Rafael is in talks to build Tamir in India, in the context of the February 2026 Special Strategic Partnership.
• The Golden Dome initiative carries critical secondary consequences:

1. Heightened Regional Threats: Chinese and Russian strategic pushback will inadvertently aggravate India’s northern security challenges.
2. Strained Supply Chains: Simultaneous demand from the Golden Dome and operations in the Gulf will likely bottleneck the U.S. interceptor industrial base, extending lead times for American-made defense systems.

Contested claims and source discrepancies

How the sources differ in kind. The Golden Dome picture rests mostly on Arms Control Association, Defense One, Axios and Breaking Defense reporting of hearings and conference remarks. Steel Dome relies heavily on Aselsan and procurement-agency statements relayed by trade outlets such as Quwa and Warsight, with limited independent verification. For Iron Dome, the best-sourced numbers are the least independent.
