Air Operations
From May 11 to May 25, ground troops supported by the Air Force tried to contain the threat, assessed the enemy dispositions and carried out various preparatory actions. Entry of the Air Force into combat action on May 26 represented a paradigm shift in the nature and prognosis of the conflict. In operation Safed Sagar, the Air Force carried out nearly 5,000 sorties of all types over 50-odd days of operations.
The Western Air Command conducted the three-week-long exercise Trishul three weeks before Kargil. During Trishul, the IAF flew 5,000 sorties with 300 aircraft using 35,000 personnel and engaged targets at high elevation in the Himalayas. The IAF claimed to have flown 550 sorties in Kargil, though just about 80 were on or close to the target. Soon after Kargil, both the commander-in-chief and senior air staff officer of the Western Air Command were mysteriously transferred to the Central and Eastern commands.
Operations in this terrain required special training and tactics. It was soon realised that greater skills and training were needed to attack the very small/miniature targets extant, often not visible to the naked eye.
The shoulder-fired missile threat was omnipresent and there were no doubts about this. An IAF Canberra recce aircraft was damaged by a Pakistani Stinger fired possibly from across the LoC. On the second and third day of the operations, still in the learning curve, the IAF lost one MiG-21 fighter and one Mi-17 helicopter to shoulder-fired missiles by the enemy. In addition, one MiG-27 was lost on the second day due to engine failure just after the pilot had carried out successful attacks on one of the enemy's main supply dumps. These events only went to reinforce the tactics of the IAF in carrying out attacks from outside the Stinger SAM envelope and avoiding the use of helicopters for attack purposes. Attack helicopters have a certain utility in operations under relatively benign conditions but are extremely vulnerable in an intense battlefield. The fact that the enemy fired more than 100 shoulder fired SAMs against IAF aircraft indicates not only the great intensity of the enemy air defences in the area but also the success of IAF tactics, especially after the first three days of the war during which not a single aircraft received even a scratch.
The terrain in the Kargil area is 16,000 to 18,000 feet above sea level. The aircraft are, therefore, required to fly at about 20,000 feet. At these heights, the air density is 30% less than at sea level. This causes a reduction in weight that can be carried and also reduces the ability to manoeuvre as the radius of a turn is more than what it is at lower levels. The larger radius of turn reduces manoeuverability in the restricted width of the valley. The engine’s performance also deteriorates as for the same forward speed there is a lesser mass of air going into the jet engine of the fighter or helicopter. The non-standard air density also affects the trajectory of weapons. The firing, hence, may not be accurate. In the mountains, the targets are relatively small, spread-out and difficult to spot visually, particularly by pilots in high speed jets.
The Indian airfields nearest to Kargil were Srinagar and Avantipur. Adampur near Jalandhar was also close enough to support air operations. Therefore, the IAF operated from these three bases. The planes used for ground attack were MiG-2ls, MiG- 23s, MiG-27s, Jaguars and the Mirage- 2000. The Mig-2l was built mainly for air interception with a secondary role of ground attack. However, it is capable of operating in restricted spaces which was of importance in the Kargil terrain.
The MiG-23s and 27s are optimised for attacking targets on the ground. They can carry a load of 4 tonnes each. This could be a mix of weapons including cannon, rocket pods, free- fall and retarded bombs and smart weapons. It has a computerised bomb sight which enables accurate weapon delivery. These planes were, therefore, ideal for use in the mountainous terrain of Kargil.
However, on May 27, the MiG-27 flown by Flt Lt Nachiketa, while attacking a target in Batalik sector, developed an engine trouble and he had to bailout. Sqn Ldr Ajay Ahuja, in a MiG-2l, went out of the way to locate the downed pilot and in the process was hit by a Pakistani surface- to-air missile (SAM). He ejected safely but his body bearing gun- wounds was returned subsequently. The state-of-the-art Mirage-2000s were used for electronic warfare, reconnaissance and ground attack. This fighter delivers its weapons with pinpoint accuracy. In addition to carrying free-fall bombs, it also fires the laser-guided bomb with deadly effects. In fact, it was this weapon that caused considerable devastation to Pakistani bunkers on the ridges at Tiger Hill and Muntho Dhalo. In the Mirage attack on Muntho Dhalo, Pakistani troops suffered 180 casualties.
Because of the need to engage Pakistani targets in the valleys and on ridges, the slower helicopter gunship became an important requirement. The load-carrying Mi-17 was modified to carry 4 rocket pods with air-to-ground rockets. This helicopter proved effective in engaging Pakistani bunkers and troops. On May 28, while attacking Point 5140 in Tololing sector, one helicopter and its crew were lost to a Stinger heat-seeking missile. Thereafter, because of the number of SAMs being fired, helicopters resorted to evasive tactics but persisted with the attacks.
The operations restricted to Kargil area did not lend themselves to the use of air power. There was a constraint of not crossing the Line of Control (LoC) to the Pakistan side. The IAF was, therefore, not at liberty to destroy the Pakistani supply lines and smash the logistic bases across the LoC. However, such attacks were done on Pakistani facilities on the Indian side of the LoC. The targets were identified along with the Army and engaged by day and by night in precision attacks by Mirage 2000s and Jaguars. Supply lines, logistic bases and enemy strong points were destroyed. As a result, the Army was able to pursue its operations at a faster rate and with fewer losses.
To obviate the threat from SAMs, bombing was done accurately from 30,000 feet above sea level or about 10,000 feet above the terrain. In these high level attacks, the infantryman does not see his own fighters and, therefore, feels that air support is not there. It is estimated that in operation Vijay, about 700 intruders were killed by air action alone. The IAF has intercepted a number of enemy wireless transmissions indicating the effectiveness of IAF attacks.
Pakistan Air Force fighters were picked up on the airborne radar of our fighters but the PAF planes did not cross to the Indian side of the LoC. Nevertheless, as a precaution, IAF , strike aircraft were accompanied by fighter escorts. After all, in the recent past no war has been won without control of the air space in which operations are conducted.
