Comparing India and Pakistan’s Air Defense Systems: A Strategic Assessment

SOURCE: AFI

In the volatile South Asian geopolitical landscape, India and Pakistan maintain robust air defense systems to counter aerial threats, reflecting their ongoing rivalry and mutual deterrence strategies. A comparative analysis of their air defense systems, as detailed in a recent infographic shared on X, reveals stark contrasts in range, radar technology, and target engagement capabilities.

With India’s layered, multi-tiered defenses contrasting against Pakistan’s more limited but evolving systems.

India’s air defense architecture is designed to counter a wide spectrum of aerial threats, from fighter jets to ballistic missiles, reflecting its need to address both Pakistan and China. The systems listed in the infographic highlight a multi-layered approach:

• S-400 Triumf (400 km, Multi-AESA, Long-Range): India’s acquisition of five S-400 regiments from Russia, with deliveries ongoing since 2021, provides a significant strategic advantage. Capable of engaging targets at 400 km, the S-400 can track up to 300 targets simultaneously using its multi-AESA radar suite, countering aircraft, cruise missiles, and ballistic missiles at speeds up to Mach 14. Deployed along the LAC with China and the LoC with Pakistan, the S-400 gives India a deep-strike interception capability, potentially neutralizing Pakistani aircraft before they reach Indian airspace.
• Barak-8 (70–100 km, EL/M-2084 AESA): A joint Indo-Israeli system, the Barak-8 (MR-SAM/LR-SAM) equips both the Indian Air Force and Navy. With a range of 70–100 km, it can engage targets at speeds up to Mach 2, using its active radar homing and EL/M-2084 AESA radar for 360-degree coverage. Its versatility makes it ideal for protecting high-value assets like airbases and naval fleets, countering Pakistan’s subsonic cruise missiles like the Babur.
• Akash (Mk1/NG, 30–70 km, Rajendra III AESA): The indigenously developed Akash system, with its Mk1 and Next Generation (NG) variants, offers medium-range defense. The Akash-NG extends the range to 70 km, engaging targets at Mach 2.5 using the Rajendra III AESA radar. Deployed extensively along the LoC, the Akash provides cost-effective protection against Pakistani fighter jets like the JF-17, though its range is outclassed by longer-range threats.
• SPYDER (15–35 km, Electro-Optic/Radar Platform): The Israeli SPYDER system, with Python-5 and Derby missiles, offers short-range defense with a 15–35 km range. Its electro-optic and radar-based targeting ensures flexibility against low-flying threats, complementing India’s layered defense.
• QRSAM (25–30 km, AESA, 360° Coverage): The Quick Reaction Surface-to-Air Missile (QRSAM), developed by DRDO, provides rapid-response defense with a 25–30 km range and 360-degree AESA radar coverage. Designed to counter agile targets, it enhances India’s ability to protect forward positions along the LoC.
• SRSAM (25 km, Naval AESA): The Short-Range SAM, primarily for naval use, offers a 25 km range with AESA radar, protecting Indian Navy assets like INS Vikrant from close-in aerial threats.

India’s systems emphasize AESA radar technology, providing superior tracking, resistance to jamming, and multi-target engagement. The S-400, in particular, gives India a significant edge, with its long-range interception capability unmatched by Pakistan.

Pakistan’s Air Defense Systems: A Defensive Posture

Pakistan’s air defense systems, while modernizing, are more limited in scope, focusing on countering India’s conventional air superiority. The infographic lists the following:

• HQ-9P/HQ-9BE (100–200 km, Mach 14): The Chinese-supplied HQ-9P and its upgraded HQ-9BE variant form the backbone of Pakistan’s long-range air defense. With a range of 100–200 km, the HQ-9 can engage targets at speeds up to Mach 14, making it capable of countering Indian aircraft like the Sukhoi-30 MKI or Rafale. However, its radar technology (likely based on the H-200 phased array) is less advanced than the S-400’s multi-AESA suite, and its deployment is limited to key strategic areas like Karachi and Rawalpindi.
• LY-80/LY-80E (40–70 km, Mach 2.5): The Chinese LY-80 (HQ-16) system provides medium-range defense, with a 40–70 km range and a target speed limit of Mach 2.5. While effective against subsonic threats like cruise missiles, its capability against high-speed targets, such as India’s BrahMos (Mach 3+), is limited. The LY-80E variant improves tracking but lacks the 360-degree coverage of India’s Barak-8 or QRSAM.
• FM-90 (15 km, Mach 1.2): The short-range FM-90, also Chinese-supplied, has a 15 km range and can engage targets up to Mach 1.2. Its limited range and speed make it vulnerable to India’s faster, standoff weapons like the SCALP missile on Rafale jets.
• Crotale (Command-Guided, Mach 2.3): The French-supplied Crotale system, used by Pakistan since the 1990s, is a command-guided SAM with a target speed limit of Mach 2.3. While effective against older threats, its technology is outdated compared to India’s AESA-based systems.
• MPQ-64 Sentinel (Mach 2.5+): The U.S.-supplied Sentinel radar, used for target detection, supports Pakistan’s air defense network but lacks the integration and range of India’s Rajendra III or EL/M-2084 radars.

Pakistan’s systems are heavily reliant on Chinese technology, with the HQ-9 offering the most credible long-range defense. However, their overall coverage, radar sophistication, and target engagement speeds lag behind India’s.

Comparative Analysis

1. Range and Coverage:
   • India’s S-400 (400 km) vastly outranges Pakistan’s HQ-9 (100–200 km), enabling India to engage threats deep inside Pakistani airspace, potentially as far as Lahore or Islamabad. The S-400’s multi-AESA radar provides superior situational awareness.
   • Medium-range systems like the Barak-8 (70–100 km) and Akash-NG (70 km) give India an edge over Pakistan’s LY-80 (40–70 km), with better radar technology and engagement envelopes.
   • Short-range systems show parity, with India’s SPYDER (15–35 km) and Pakistan’s FM-90 (15 km) offering similar ranges, though India’s AESA-based QRSAM provides better flexibility.
2. Target Speed and Engagement:
   • The S-400’s ability to engage Mach 14 targets outclasses the HQ-9’s similar capability, as the former’s radar and missile suite (e.g., 48N6E3 missile) are more advanced.
   • Pakistan’s LY-80 and Crotale struggle against high-speed threats like the BrahMos (Mach 3+), while India’s Barak-8 and Akash-NG can handle such targets more effectively.
   • The FM-90’s Mach 1.2 limit makes it ineffective against India’s Rafale-Meteor combo (Mach 4.5), whereas India’s SPYDER and QRSAM can engage faster threats.
3. Radar Technology:
   • India’s reliance on AESA radars (S-400, Barak-8, Akash, QRSAM) provides better tracking, resistance to electronic countermeasures, and multi-target engagement compared to Pakistan’s phased array (HQ-9, LY-80) and command-guided (Crotale) systems.
   • The S-400’s multi-AESA suite and the Barak-8’s EL/M-2084 offer 360-degree coverage, a capability Pakistan’s systems largely lack, except for the planned NASAMS.
4. Strategic Depth:
   • India’s layered defense, with long-, medium-, and short-range systems, provides depth and redundancy, crucial for a two-front scenario against Pakistan and China. The S-400, in particular, acts as a force multiplier, deterring Pakistani air incursions.
   • Pakistan’s systems, while improving with the HQ-9 and potential NASAMS, are more defensive, focusing on protecting key cities and military installations rather than projecting power.

India’s air defense superiority gives it a significant edge in a potential conflict. The S-400’s range and radar capabilities allow India to dominate airspace, forcing Pakistan to operate cautiously, especially with assets like F-16s or JF-17s. India’s ability to counter Pakistan’s subsonic cruise missiles (e.g., Babur) with Barak-8 and Akash systems neutralizes a key asymmetric threat. Moreover, India’s indigenous systems like Akash and QRSAM, developed under Make in India, reduce reliance on foreign suppliers, ensuring operational sustainability.

Pakistan, however, faces challenges with its shorter-range systems and less advanced radar technology. The HQ-9 provides a credible deterrent against Indian aircraft, but its limited deployment and inferior radar capabilities compared to the S-400 constrain its effectiveness. The planned NASAMS acquisition signals modernization, but until operational, Pakistan’s air defenses remain vulnerable to India’s standoff weapons, such as the Rafale-Meteor (150+ km range) or BrahMos.
