Pakistan Navy – Special Mention
The Pakistan Navy, though smaller in size compared to regional rivals, operates with a doctrine built around agility, precision, and sea denial. This strategy is tailored to its primary theater, the Arabian Sea, where geography and short engagement distances give the defender a unique advantage.
Today, Pakistan’s submarine arm remains its ace card. The Agosta-90B Khalid-class submarines, equipped with Air-Independent Propulsion (AIP), can operate silently for extended periods and strike targets with heavyweight torpedoes or Exocet SM39 anti-ship missiles. These subs can threaten high-value targets like aircraft carriers or large destroyers before they ever approach Pakistani waters. The confined North Arabian Sea further amplifies their lethality, as enemy warships have limited maneuvering space and reduced escape options.
The Navy’s modernization has also embraced indigenous missile technology. In 2018, the Harbah naval cruise missile was successfully launched from the fast-attack craft PNS Himmat, striking a target beyond the horizon. Harbah offers both anti-ship and land-attack capabilities with a range of up to 280 kilometers, surpassing older imported systems. Complementing this is the Zarb coastal defense missile, tested in 2017, which allows land-based targeting of hostile ships.
Additionally, new Type 054A/P frigates, equipped with advanced LY-80 long-range surface-to-air missiles, are expanding Pakistan’s defensive perimeter. This layered approach — combining submarines, fast-attack craft, shore-based missiles, and modern frigates — means that any adversary would face multiple, simultaneous threats.
In strategic terms, Pakistan cannot match the Indian Navy in numbers, but it does not aim to. Instead, it focuses on making the Arabian Sea a high-risk zone for hostile operations. The doctrine is simple: deny the enemy freedom of maneuver, protect maritime trade routes, and keep strategic ports like Karachi and Gwadar secure. With growing integration of drones, electronic warfare, and stealth platforms, the Pakistan Navy is positioning itself as a potent asymmetric deterrent, ensuring that any potential naval confrontation comes at an unacceptably high cost for its opponent.
