PNS Shah Jahan (DDG-186) was a Tariq-class destroyer in service with the Pakistan Navy since being recommissioned in 1994. Based on the British design, Type 21 frigate, she previously served in the Royal Navy as HMS Active as a general purpose frigate.^[3]

In 1998–2008, the extensive engineering modernization and midlife upgrade program by the KSEW Ltd. at the Naval Base Karachi reclassified her status as guided missile destroyer.^[4]

Service history

She was designed and constructed by the Yarrow Shipbuilders, Ltd. at Glasgow in Scotland, she was laid down on 30 October 1974, and was launched on 19 July 1978.^[3] She eventually commissioned on 19 July 1978 in the Surface Fleet of the Royal Navy as HMS Active.^[3] During her service with the Royal Navy, she was notable for her wartime operations during the Falklands War with Argentina.^{: 104 [5]}

On 3 October 1994, she was purchased by Pakistan after the successful negotiation with the United Kingdom, along with PNS Tippu Sultan.^: 51 [6]

Upon arriving in Karachi, she underwent an extensive modernization and mid-life upgrade program by the KSEW Ltd. at the Naval Base Karachi in 1998–2002.^[3]

Her wartime performance included in deployments in patrolling off the Gulf of Aden, Gulf of Oman, Persian Gulf, Arabian Sea as well as deploying in the Mediterranean Sea when she was part of the multinational CTF-150.^[7]

On 12 January 2021, Shah Jahan was sunk as a target by the Pakistan Navy during a live-fire drill in the North Arabian Sea.^[8][9]
