The PNS Mehran attack was an attack/shooting by Tehrik-i-Taliban Pakistan (TTP) and Al Qaeda which took place on 22 May 2011, at PNS Mehran, the headquarters of the Pakistan Navy's Naval Air Arm and the most populous Pakistani military installation, located near the PAF's Faisal Air Force Base of Karachi, Sindh.

In the course of the event, 15 attackers killed 18 military personnel and wounded 16 in a sophisticated terrorist attack which lasted 16 hours. Two American-built P-3C Orion surveillance aircraft were destroyed.

According to the United States and Western intelligence sources, the attack was far more dangerous than the 2009 Pakistan Army General Headquarters attack, and was better planned and more rehearsed than the previous attack. It was the biggest attack on the Navy and its assets since 1971, and is believed to have been the last major attack of militant mastermind Ilyas Kashmiri. The Special Service Group (Navy) (SSG (N)), carried out the counter-attack, which was the largest operation led by SSG (N). Provided by Wikipedia
