, the Pakistan Navy eventually succeeded getting the proposal approved for building the nuclear-powered submarine whose delivery is expected to between 2028, according to the Pakistan Navy officials. In April 2014, the Navy announced that submarine operations would move from Naval Base Karachi to the new Jinnah Naval Base in Ormara. Submarine training takes place at PNS Abdoze in Karachi. In May 2008, the Navy established the Fleet Acoustic Research and Classification Centre to validate submarine safety standards and to act as an underwater listening post to track unauthorised submarines. Auxiliaries, mine countermeasures, and amphibious warfare The Navy has six replenishment oil tankers, three minehunters, and four Griffon 2000TD hovercraft for the amphibious warfare. The Landing Craft Mechanized (LCM) are the important and center pieces for the amphibious operations undertaken by the Marines Corps and expeditionary actions by the Army as the two of the LCMs are commissioned by the Navy after being handed over by the KSEW Ltd. in 2016. In 1987, the Pakistan Navy commissioned , the , fleet tanker from China that was followed by the commissioning of , of the Poolster class, from the Royal Netherlands Navy in 1988. In 1995, Poolster-class PNS Moawin was subjected to a serious fire accident that claimed valuable life during the refitting of the vessel in Karachi. The Navy also operates two coastal tankers that were indigenously designed and locally built at the Karachi Shipyard— PNS Gwadar and PNS Kalmat— commissioned in 1984 and in 1992. In 2011, the Navy commissioned two more small tankers/utility ships (STUS) —PNS Madadgar and PNS Rasadgar —to support the logistics and marine operations in the open sea. In 1992, the Navy increased its operational capabilities in mine countermeasures with the commissioning of from the French Navy, followed by the technology transfer to Pakistan which led the commissioning of two more mine countermeasure vessels from in 1996 and 1998. Together with the Munsif-class minehunters and the replenishment oil tankers, these classes of ships are commissioned and complemented in the 9th Auxiliary Squadron. In 2018, the Pakistan Navy commissioned another which was locally engineered and constructed from the crucial design guidance from Turkey– the fleet tanker is noted for being the largest warship ever built in Pakistan. In 2011, the Pakistan Navy established the 21st Auxiliary Squadron to further support its fleet's logistics operations to fulfill the requirements of hydrological survey in the ocean, and the
