Who Has MIRVs? An Overview of Countries with MIRV Ballistic Missiles (2026)

A Multiple Independently Targetable Re-entry Vehicle (MIRV) allows one ballistic missile to strike multiple targets by deploying separate nuclear warheads. As of 2026, six countries are known or widely believed to have operational nuclear-capable MIRV missiles: United States, Russia, China, United Kingdom, France, and India. Pakistan and North Korea have claimed or are developing MIRV-capable systems (e.g. Pakistan’s Ababeel missile tested in 2017 and North Korea’s Hwasong-17 ICBM development), but public details are sparse. We will summarize each nation’s status (year of first test/deployment, missile types, warheads per missile, confidence level) and highlight others. We also explain the MIRV technology (how one missile carries multiple warheads), its strategic effects (such as strengthening deterrence and complicating arms control), and recent news (tests, treaties, modernization up to 2026). The report includes a comparative table of operational vs claimed MIRV programs and a timeline chart of key events. All claims are cited from defense sources, SIPRI/IISS reports, and reputable news.

Countries with Operational MIRV Weapons

• United States: The U.S. pioneered MIRVs in the late 1960s. Its land-based ICBM LGM-30G Minuteman III entered service in 1970 and was initially fitted with 3 nuclear warheads (each ~300–350 kt). Under current treaties, Minuteman III missiles carry only one warhead, but they retain the capacity to return to three if needed. The U.S. Navy’s UGM-133 Trident II D5 SLBM (submarine-launched) has been deployed since 1990. Each Trident II D5 can carry up to 8 MIRV warheads (though New START limits deployed load to 8) – this missile is used by both U.S. and UK submarines (see UK entry below). The U.S. is developing a new ground-based ICBM (LGM-35 “Sentinel”), expected by 2030, which will carry up to 2 warheads (down from 3) on a modernized W87 warhead.

• Russia: The Soviet Union first deployed MIRV ICBMs in the 1970s. The R-36M (SS-18 “Satan”) heavy silo-based ICBM entered service in 1975 and carried up to 10 warheads. (Russia is replacing these with newer systems.) The mobile RT-2PM Topol (SS-25) ICBM was single-warhead, but its successor RS-24 Yars (SS-27 Mod 2), deployed around 2010, is MIRV-capable with up to 4 warheads. Russian SLBMs: the legacy R-29R (SS-N-18 “Stiletto”) had 4 warheads (service from 1970s), replaced by the RSM-56 “Bulava” (SS-N-32) on Borei-class subs, deployed in 2013 with up to 6 warheads (though New START deployments usually carry 4). Overall, Russia maintains dozens of MIRVed missiles in its ICBM and SLBM forces (confidence high).

• China: China fielded MIRVs more recently. Its DF-5B (CSS-4 Mod 4) silo-based ICBM, an upgrade of the 1980s DF-5A, became MIRV-capable in the 2010s and can carry up to 5 warheads. China’s road-mobile DF-41 (CSS-X-20) ICBM (tested late 2010s, deployed 2020s) likely carries 3 MIRV warheads. (China’s older DF-31 series are single-warhead.) The exact loading (number of warheads per missile) is uncertain, but SIPRI notes China is expanding silos for DF-5B and DF-41 and could field dozens of MIRVed missiles. China publicly acknowledges MIRV tech and US intelligence confirms DF-5B and DF-41 MIRV capability.

• United Kingdom: The UK’s Trident II D5 SLBM carried on its Vanguard-class submarines is MIRV-capable. Each missile can hold up to 8 warheads (same as U.S. specification), but the UK limits total warheads to 48 across its 16 missiles (an average of 3 per missile). The UK deployed Trident II starting in 1994; thus its MIRV force has been operational since the 1990s. (Under the 1998 Strategic Defence Review, the UK announced a 3-per-missile loading; the number may be adjusted by future policy changes.)

• France: France’s sea-based deterrent uses M51 SLBMs on its Triomphant-class submarines. The M51 entered service around 2010. Its first version, M51.1, is armed with up to 6 TN75 warheads (each ~100 kt). An upgraded M51.2 also carries 6 (with a new warhead type). France is upgrading to M51.3/M51.4 by mid-2020s with similar MIRV loads. With four SSBNs, France keeps its MIRVed missiles at sea continually.

• India: In March 2024, India successfully tested a MIRV-equipped missile. Prime Minister Modi confirmed that Agni-V, India’s long-range ballistic missile (ICBM), carried multiple warheads in the test dubbed “Mission Divyastra”. This made India the sixth country to demonstrate indigenous MIRV capability. (India has not publicly disclosed how many warheads Agni-V can carry, but 3 is often reported.) Agni-V (range ~5,000 km) entered service in 2022 for single warhead, and the 2024 test showed it can carry a MIRV payload. Indian sources say this enhances deterrence, but full operational deployment details are still under study. Given the official test and DRDO announcements, India’s MIRV status is confirmed.

Other declared nuclear states (Pakistan, North Korea, Israel) do not yet have proven MIRV arms.

Countries Developing or Claiming MIRV Systems

• Pakistan (claimed): Pakistan has publicly stated an interest in MIRVs. In 2017, Pakistan’s military press release announced a test of the Ababeel missile, and U.S. intelligence specifically referred to it as “the MIRV version of the Ababeel”. The Ababeel is a medium-range missile (reportedly ~2,200 km range) that is believed to carry 3–6 warheads in design, but Pakistan has not disclosed exact payload. These claims have not been independently verified; satellite images and analysts have noted possible changes to the missile body, but warhead tests are secretive. We mark this as claimed development: evidence is limited to the 2017 test and Pakistani statements, so confidence is moderate.

• North Korea (developing): North Korea has signaled interest in multi-warhead missiles. Its large Hwasong-17 ICBM (first successfully tested Nov 2022) has a big payload fairing suitable for MIRVs. Supreme Leader Kim Jong Un said in 2021 that North Korea was finalizing “guidance technology for multi-warhead” missiles. No test has yet confirmed actual MIRVs; all North Korean launches so far released a single warhead or mock-up. Analysts see North Korea’s actions and statements as a pursuit of MIRV capability, but without public tests of multiple warheads. So we list North Korea as developing MIRVs – possibly demonstrated as concepts but not yet deployed. (Some open sources warn DPRK’s claims may be propaganda.)

• Others (not confirmed): No other states are known to have functioning MIRV missiles. For example, Israel’s Jericho ballistic missiles are not confirmed as MIRV-equipped, and Iran has no operational nuclear-armed ballistic missiles. South Africa, once interested in advanced re-entry vehicles, dismantled its arsenal. Thus no data to list for these.

How MIRVs Work: Technology and Limits

A MIRV system has a post-boost vehicle (bus) on top of the missile’s final stage. After booster burnout, the bus maneuvers, using small thrusters, to aim different warheads at different targets. Each warhead sits in its own reentry vehicle (RV). During reentry, each RV follows a separate trajectory toward its assigned target. This lets one missile strike several targets (even hundreds of kilometers apart).

Advantages: MIRVs greatly multiply destructive capability without more launchers. They make it harder to shoot down all warheads (an ABM defense must kill multiple warheads per missile). They improve deterrence “punch” – a nation needs fewer missiles to threaten many targets.

Limits: MIRVs also have drawbacks. Each warhead is smaller (to stay within payload weight). Modern MIRVs must weigh less, so yields can be lower than an equivalent single warhead. Also, MIRVs require very accurate deployment (guidance precision and bus control). Developing MIRV reliability is technically challenging. Treaties like New START place limits on warhead deployments, which partly restrict how many MIRVs a country can field on missiles.

Strategic Implications

MIRVs complicate strategic stability. On one hand, they strengthen a country’s second-strike deterrent by enabling assured large nuclear responses even if some missiles are destroyed. On the other hand, MIRVs can spur arms races: if Country A can target many sites in Country B with fewer missiles, Country B may feel vulnerable and build more missiles or ABM defenses. This can erode crisis stability, as each side worries about preemptive strikes wiping out forces.

Arms control is harder with MIRVs. A missile count can be cut while warhead count remains high. Verification of exact warhead loadouts (for instance under treaties) is complex. This is why treaties often limit MIRV specifically (e.g., New START limits deployed warheads) or testing bans on new warheads. MIRVs can also reduce the value of fixed silo commands, pushing countries toward mobile launchers.

In short, MIRVs make nuclear forces more efficient but risk a new arms competition. Experts warn that countries with MIRVs can threaten “hard targets” (like missile silos or command bunkers) with fewer missiles, raising pressure on adversaries to respond in kind.

Recent Developments (up to 2026)

• India: As noted, India’s first MIRV test (Agni-5) in March 2024 is a major recent development. India announced more tests planned. (Some reports mention an upcoming Agni-VI with MIRVs). This puts India in the global MIRV club in the 2020s.
• USA/Russia: Both superpowers continue modernizing. The U.S. is preparing its Sentinel ICBM (with 2 warheads) and upgrading Trident II (Life Extension II). Russia has begun deploying the RS-28 Sarmat ICBM (first flight tests by 2022, early deployment by 2026); Sarmat will carry 10+ MIRVs (officially up to 10) and enter service soon. Russia also is developing the RS-28 and Kinzhal hypersonic systems (some non-MIRV). Both US and Russia have left the New START treaty in 2023, which may alter MIRV loadings (they are no longer bound to reduce to 1550 warheads each).
• China: The PLA has accelerated silos expansion (over 300 silos spotted by 2023) and is deploying more DF-41 units. China’s policymakers say they aim to “no first use,” but with MIRVs they add conventional threat as well. Also, China is developing a hypersonic glide vehicle (DF-ZF) that could someday carry multiple warheads, though current tests (late 2020s) have been limited-range.
• Pakistan: No further public MIRV tests since 2017. Pakistan is instead focusing on tactical nuclear weapons (battlefield nukes) and cruise missiles. But some analysts say development of MIRV technology is likely ongoing in secret. Pakistan’s ballistic missile inventory (Shaheen, Ghaznavi) remains mostly single-warhead, aside from Ababeel.
• North Korea: After early 2020s ICBM tests, DPRK has not officially confirmed any MIRV payload test. However, its state media continues to develop missile capabilities in speeches. Satellite imagery of missile infrastructure suggests DPRK working on multiple warhead re-entry vehicles, but confirmation is lacking.

On arms control, key events include: the end of New START in 2023 (both US/Russia free from treaty limits), Iran nuclear talks (no direct MIRV relation), and renewed proposals to regulate MIRVs by arms control advocates (Stimson Center workshop 2025 on MIRV arms control).

Proliferation Risks and Controls

MIRV technology is sensitive: it requires advanced manufacturing and guidance expertise. Non-nuclear countries have little incentive to pursue MIRVs unless also seeking nuclear arms. Export controls under MTCR (Missile Technology Control Regime) restrict sharing of long-range missile tech, including bus guidance. No known proliferation networks for MIRV specifically exist (unlike for ballistic missiles generally). Countries like North Korea and Pakistan have received foreign help for basic missile tech, but MIRVs are largely developed indigenously. Still, illicit networks could theoretically transfer components or know-how (e.g. precision microelectronics). Monitoring exports of space guidance and warhead miniaturization tech is important.

Verification Challenges and Indicators

It is hard for outsiders to verify how many warheads a deployed missile carries. Satellite imagery can spot new silo fields or missile deployments, but not warhead counts. Test launches revealing multiple reentry vehicles are rare (they risk revealing design). Open-source indications include: small warhead RV shapes in missile parade footage, statements by leaders, mentions in defense budgets (e.g. France’s mention of M51.3 warhead upgrade). Intelligence agencies rely on signals (text intercepts) and debris recovery from tests. For example, the US detected Russian tests of the Topol-M MIRV variant by analyzing flight data. In treaty inspection regimes, inspectors can count missiles and warheads under warhead counting protocols, but MIRV buses add complexity.

FAQ

Q1: What is a MIRV and why does it matter?
A1: A MIRV (Multiple Independently Targetable Re-entry Vehicle) is a missile payload carrying multiple nuclear warheads, each aimed at a different target. This means one missile can hit several targets. MIRVs matter because they greatly increase a missile force’s firepower and complicate missile defense. They allow a nation to hold more targets at risk and can destabilize nuclear deterrence if rivals feel pressure to match them.

Q2: How many countries have MIRV-capable missiles?
A2: As of 2026, six countries have operational nuclear MIRVs: USA, Russia, China, UK, France, and India. Each of these has ballistic missiles (ICBM or SLBM) that can carry multiple warheads. Pakistan and North Korea are also developing MIRV systems, but their status is not confirmed.

Q3: Which missiles carry MIRVs in those countries?
A3: Examples: USA’s Minuteman III ICBM (3 warheads) and Trident II SLBM (8 warheads); Russia’s R-36M ICBM (10 warheads) and RSM-56 Bulava SLBM (6 warheads); China’s DF-5B ICBM (up to 5 warheads) and DF-41 ICBM (3 warheads); UK’s Trident II SLBM (8 warheads, 3 carried per policy); France’s M51 SLBM (6 warheads); India’s Agni-V ICBM (tested with multiple warheads in 2024).

Q4: What are the challenges in verifying MIRV deployments?
A4: Verifying MIRVs is hard because satellites or sensors cannot count warheads in a silo or submarine. Countries only declare overall warhead numbers. Test flights normally release only one re-entry vehicle, so multiple-warhead tests are rare. Open-source experts look for clues like specialized bus vehicles, warhead shapes, and official statements. Treaty inspections (like under START) require counting each missile and warhead, but MIRVs make simple launcher counts misleading. This ambiguity complicates arms control.

Q5: What is a recent news on MIRV development?
A5: A big recent event was India’s first MIRV test in March 2024. Also, Russia is deploying its new Sarmat ICBM (10-warhead MIRVs) starting mid-2020s, while China is fielding more silos for its DF-5B MIRVed ICBMs. In arms control, the US and Russia have ended New START (in 2023), which may influence future MIRV limits. DPRK’s leadership has announced work on “multi-warhead” missiles, but no public launches have tested multiple nuclear re-entry vehicles yet.
