India vs Pakistan 2025: Nuclear & Strategic Capabilities in Detail
Published: Saturday, May 10, 2025 | By The Dainik News Team
The nuclear and strategic capabilities of India and Pakistan remain central to the security dynamics of South Asia. Both countries possess significant nuclear arsenals and delivery systems, shaping their deterrence postures and military doctrines. This detailed post examines the size, composition, doctrines, delivery platforms, and strategic implications of their nuclear forces as of 2025.
Nuclear Arsenal Size and Composition
According to recent estimates from the Arms Control Association and other authoritative sources, India possesses approximately 180 nuclear warheads, while Pakistan is close behind with around 170 warheads. Both nations have steadily expanded their arsenals over the past two decades, with India overtaking Pakistan in warhead count in 2024.
| Attribute | India | Pakistan |
|---|---|---|
| Estimated Warhead Count (2025) | ~180 | ~170 |
| Warhead Types | Plutonium and Highly Enriched Uranium (HEU) based | Primarily Plutonium based |
| Warhead Yield Range | 5 to 200+ kilotons | 5 to 100+ kilotons |
| Declared Nuclear Triad | Yes (Land, Air, Sea) | Partial (Land, Air; Sea under development) |
| Delivery Platforms | Ballistic missiles, cruise missiles, strategic bombers, SSBNs | Ballistic missiles, cruise missiles, strategic bombers (limited sea-based capability) |
Nuclear Doctrine and Command Structure
India adheres to a No First Use (NFU) nuclear doctrine, pledging to use nuclear weapons only in retaliation to a nuclear attack. India emphasizes credible minimum deterrence, aiming to maintain a survivable and effective nuclear force to deter aggression without engaging in arms races.
Pakistan, in contrast, has never adopted an NFU policy. Its doctrine includes Full Spectrum Deterrence, which allows for the use of tactical nuclear weapons to counterbalance India’s conventional military superiority and rapid mobilization doctrines such as "Cold Start." Pakistan’s nuclear command authority is civilian-controlled but closely integrated with military leadership.
Land-Based Ballistic Missiles
Both nations have developed an array of ballistic missiles capable of delivering nuclear warheads at various ranges:
| Missile | Country | Range (km) | Warhead Type | Notes |
|---|---|---|---|---|
| Agni-I | India | 700-900 | Nuclear/Conventional | Short-range ballistic missile (SRBM) |
| Agni-II | India | 2,000-3,000 | Nuclear/Conventional | Medium-range ballistic missile (MRBM) |
| Agni-III | India | 3,000-5,000 | Nuclear | Intermediate-range ballistic missile (IRBM) |
| Agni-IV | India | 3,500-4,000 | Nuclear | Advanced MRBM with improved accuracy |
| Agni-V | India | 5,000-5,500+ | Nuclear | Intercontinental ballistic missile (ICBM), MIRV capable |
| Shaheen-I | Pakistan | 750-900 | Nuclear/Conventional | SRBM, road-mobile |
| Shaheen-II | Pakistan | 1,500-2,000 | Nuclear/Conventional | MRBM, solid-fuel |
| Shaheen-III | Pakistan | 2,750-3,000 | Nuclear | Extended MRBM, strategic deterrent |
| Ghauri-II | Pakistan | 1,500-2,000 | Nuclear/Conventional | Liquid-fueled MRBM, less reliable |
Sea-Based Nuclear Capabilities
India has operationalized its nuclear triad with the deployment of the INS Arihant, an indigenously built nuclear-powered ballistic missile submarine (SSBN) capable of launching K-15 and K-4 submarine-launched ballistic missiles (SLBMs). This sea-based leg provides survivability and second-strike capability, critical for credible deterrence.
Pakistan is developing sea-based nuclear capability, with the Babur-3 submarine-launched cruise missile (SLCM) reportedly operational or near operational. However, Pakistan’s SSBN program is still in nascent stages, and the nuclear triad is not yet fully realized.
Air-Delivered Nuclear Weapons
India’s air force can deliver nuclear weapons via fighter-bombers such as the Mirage 2000, Jaguar, and the Su-30MKI. India maintains approximately 48 aircraft-based nuclear warheads.
Pakistan’s air-delivered nuclear capability is centered on modified F-16 and Mirage III/V aircraft, with an estimated 35 air-based nuclear warheads.
Tactical Nuclear Weapons and Doctrinal Differences
Pakistan maintains a policy of “full spectrum deterrence” which includes the use of tactical nuclear weapons (TNWs) to deter India’s conventional superiority and rapid mobilization doctrines. Pakistan’s TNWs are reportedly stored near the border and include short-range ballistic and cruise missiles with lower yields.
India officially adheres to a No First Use (NFU) policy, pledging to use nuclear weapons only in retaliation to a nuclear strike. However, recent statements from Indian officials have suggested a possible re-examination of this stance amid evolving security challenges.
Command and Control Structures
Both countries maintain civilian control over their nuclear arsenals through respective command authorities:
- India: Nuclear Command Authority (NCA), headed by the Prime Minister, oversees strategic decisions and control of nuclear weapons.
- Pakistan: National Command Authority (NCA), chaired by the Prime Minister, controls strategic forces and nuclear weapons deployment.
Strategic Implications and Regional Stability
The near parity in nuclear arsenals between India and Pakistan creates a delicate balance of terror, deterring full-scale conventional war but increasing risks of escalation through miscalculation or limited conflict. Both nations continue to modernize delivery systems, warheads, and command systems to maintain credible deterrence.
The ongoing tensions, including the 2025 cross-border strikes and military operations, underscore the critical importance of diplomatic efforts and confidence-building measures to prevent nuclear escalation.
“With nearly equal nuclear arsenals, both India and Pakistan walk a tightrope of deterrence and risk. The challenge lies in managing crises without crossing thresholds that could trigger catastrophic consequences.” – Arms Control Association, 2025
