Naval Operations
While the Army and the Air Force readied themselves for the battle on the heights of Kargil, Indian Navy began to draw out its plans. Unlike the earlier wars with Pakistan, this time the bringing in of the Navy at the early stages of the conflict served to hasten the end of the conflict in India's favor.
In drawing up its strategy, the Navy was clear that a reply to the Pakistani misadventure had to be two-pronged. While ensuring safety and security of Indian maritime assets from a possible surprise attack by Pakistan, the Indian imperative was that all efforts must be made to deter Pakistan from escalating the conflict into a full scale war. Thus, the Indian Navy was put on a full alert from May 20 onwards, a few days prior to the launch of the Indian retaliatory offensive. Naval and Coast Guard aircraft were put on a continuous surveillance and the units readied up for meeting any challenge at sea.
Time had now come to put pressure on Pakistan, to ensure that the right message went down to the masterminds in that country. Strike elements from the Eastern Fleet were sailed from Visakhapatnam on the East Coast to take part in a major naval exercise called 'SUMMEREX' in the North Arabian Sea. This was envisaged as the largest ever amassing of naval ships in the region. The message had been driven home. Pakistan Navy, in a defensive mood, directed all its units to keep clear of Indian naval ships. As the exercise shifted closer to the Makaran Coast, Pakistan moved all its major combatants out of Karachi. It also shifted its focus to escorting its oil trade from the Gulf in anticipation of attacks by Indian ships.
As the retaliation from the Indian Army and the Air Force gathered momentum and a defeat to Pakistan seemed a close possibility, an outbreak of hostilities became imminent. Thus the naval focus now shifted to the Gulf of Oman. Rapid reaction missile carrying units and ships from the fleet were deployed in the North Arabian Sea for carrying out missile firing, anti-submarine and electronic warfare exercises. In the absence of the only aircraft carrier, Sea Harrier operations from merchant ships were proven. The Navy also readied itself for implementing a blockade of the Pakistani ports, should the need arise. In addition, Naval amphibious forces from the Andaman group of islands were moved to the western sea-board.
In a skilful use of naval power in the form of 'Operation Talwar', the 'Eastern Fleet' joined the 'Western Naval Fleet' and blocked the Arabian sea routes of Pakistan. Apart from a deterrent, the former Prime Minister Nawaz Sharief later disclosed that Pakistan was left with just six days of fuel (POL) to sustain itself if a full fledged war broke out.
