India has historically leveraged its naval strength to exert strategic pressure on Pakistan, particularly through maritime blockades and port strikes. These actions have significantly impacted Pakistan's economy and military operations.
Pakistan’s heavy dependence on maritime trade makes it particularly vulnerable. The Indian Navy, with its superior surface fleet, submarines, maritime strike aircraft, and missiles, is well-positioned to exploit this vulnerability if required.
Given Pakistan's heavy reliance on maritime trade through Karachi, a blockade or targeted strikes by the Indian Navy could severely disrupt its economy and military logistics. Historical operations demonstrate India's capability to execute such strategies effectively.
How Indian Navy Could Cripple Pakistan’s Economy
1. Strategic Importance of Karachi and Gwadar: Pakistan’s economy relies heavily on maritime trade. Over 90% of its international trade (including vital oil imports) passes through the Port of Karachi. Other ports like Port Qasim and the relatively new Gwadar Port (China-funded) are growing but still secondary. Karachi remains the main artery, a vulnerability India knows and has exploited historically.
Possible Actions Indian Navy Can Take:
1. Naval Blockade: Preventing Entry and Exit of Ships into Pakistani Ports
Indian Navy warships, submarines, and maritime aircraft could enforce a blockade just outside Pakistan’s Exclusive Economic Zone (EEZ) - say, 200–300 nautical miles out, so as not to trigger direct combat with neutral commercial vessels.
Impact:
- No oil = Pakistan’s fuel supplies choke in weeks.
- Exports of textiles (Pakistan’s biggest export) stop.
- Food and industrial imports dry up.
- Foreign exchange reserves collapse rapidly.
2. Sea Denial Using Submarines
- INS Chakra (nuclear-powered) and conventional diesel-electric submarines (like Kalvari-class) can conduct sea denial operations.
- Methods:
- Laying sea mines near Karachi approaches.
- Attacking merchant vessels covertly using torpedoes or anti-ship missiles.
- Psychological Effect: Insurance premiums skyrocket for vessels visiting Pakistani ports. Many shipping companies avoid Pakistan altogether, even if no direct attacks happen.
3. Missile Strikes on Port Infrastructure
- Targeting:
- Fuel storage tanks.
- Cranes and container terminals.
- Naval bases like PNS Mehran, PNS Qasim.
- Weapons:
- BrahMos supersonic cruise missiles launched from Indian destroyers (like INS Kolkata) or submarines.
- Effect:
- Cripples Pakistan Navy’s ability to sortie ships.
- Disrupts cargo handling capacity for months.
4. E. Cyber and Electronic Warfare at Sea
- Indian Navy’s Information Warfare division can jam communications around Pakistani ports.
- Hacking into Pakistan’s maritime traffic systems (AIS - Automatic Identification Systems) could cause shipping chaos, collisions, and port slowdowns.
- Combined with physical disruption, this would paralyze Pakistan's port operations without necessarily escalating into full-blown war.
Summary of Economic Impact
- Immediate: Fuel shortages, inflation, panic buying, market crashes.
- Medium-term: Industrial collapse, textile exports crash, widespread layoffs.
- Long-term: Investor confidence in Pakistan collapses; foreign reserves evaporate.
Current Capabilities and Strategic Options
Western Naval Command (WNC): As the primary force on India's western seaboard, the WNC is equipped with advanced assets, including the aircraft carrier INS Vikramaditya, Delhi-class destroyers, Talwar-class frigates, and Sindhughosh-class submarines. This command plays a crucial role in any maritime strategy against Pakistan.
Surveillance and Intelligence: India has enhanced its maritime surveillance through platforms like the P-8I Poseidon aircraft, which provide anti-submarine warfare capabilities and real-time intelligence, crucial for monitoring Pakistani naval movements.
Indigenous Shipbuilding: India is focusing on strengthening its naval fleet through indigenous shipbuilding programs, including the development of advanced aircraft carriers and submarines, to maintain maritime dominance.
Historical Precedents by Indian Navy:
Operation Trident (1971): On December 4, 1971, the Indian Navy launched a surprise attack on Karachi port, sinking multiple Pakistani vessels and destroying vital fuel storage tanks. This operation marked the first use of anti-ship missiles in the region and led to a partial blockade of Karachi, severely disrupting Pakistan's naval capabilities and economy.
Operation Python (1971): Following Operation Trident, on December 8, 1971, the Indian Navy executed another assault on Karachi, causing further damage to port facilities and oil reserves. These operations collectively forced Pakistan to declare a complete blockade of Karachi harbor, effectively granting India control over the Arabian Sea during the conflict.
Operation Talwar (1999): During the Kargil War, the Indian Navy deployed its Eastern and Western Fleets to the North Arabian Sea, creating an unofficial blockade that choked Pakistan's sea-based trade routes. The Navy also intercepted a North Korean cargo ship carrying missile parts to Pakistan, highlighting its role in preventing arms supplies during the conflict.
