The Pakistan Navy is reportedly facing significant challenges with the Turkish-led modernization of its Agosta 90B submarines, which has inadvertently increased their noise levels, making them more detectable by the Indian Navy’s advanced anti-submarine warfare systems. This upgrade, aimed at extending the submarines’ service life and enhancing their capabilities, has instead compromised their stealth features, with noise levels rising by 10-15 dB, significantly affecting their operational effectiveness. As tensions rise in the region, this development underscores Pakistan’s vulnerabilities in underwater deterrence and may compel a shift towards alternative suppliers like France or a reliance on Chinese submarines. For India, this situation validates the strategic advantages of its own submarine investments, reinforcing its dominance in the Indian Ocean.
