Overview

  • On August 15, 2025, Pakistan Navy launched its third export-variant Hangor-class submarine, designated PNS MANGRO, at Wuchang Shipbuilding’s Wuhan facility.
  • Vice Admiral Abdul Samad said the new boat’s advanced sensor suite and weaponry will help sustain regional power equilibrium and maritime stability.
  • Under a 2015 agreement, four Hangor boats are built in China and four will be constructed at Karachi Shipyard and Engineering Works Ltd under a Chinese technology-transfer program.
  • The eight-boat acquisition, originally scheduled for delivery between 2022 and 2028, has experienced delays, with only three launches completed to date.
  • Pakistan has not revealed key subsystems or armaments for the Hangor class, fueling analyst assumptions of Stirling AIP propulsion and potential Babur-3 SLCM deep-strike capability.
