By 16 June,
IAF was able to open up the laser-guided bombing campaign with the help of Jaguars and Mirage-2000. Daily photo-recce along the LOC by Jaguars escorted by Mirage-2000s, which had continued from the beginning of operations, proved crucial to both the aerial bombing campaign as well as the Indian artillery, helping the latter in accurately shelling Pakistani positions in the Dras-Kargil and Gultari Sectors. While the photo-recce missions typically did not involve deliberate border violations, there were a total of 37 technical violations (which emanate as a consequence of kinks and bends in the geographical boundaries). Typically, these averaged to a depth of five nautical miles, except on one occasion when the IAF fighters apparently cocked-a-snoot at the PAF and came in 13 miles deep.
The Mirage-2000s scored at least five successful laser-guided bomb hits on forward dumping sites and posts. During the last days of operations which ended on 12 July, it was clear that delivery accuracy had improved considerably. Even though night bombing accuracy was suspect, round-the-clock attacks had made retention of posts untenable for Pakistani infiltrators. Photo-recce of Pakistani artillery gun positions also made them vulnerable to Indian artillery.
The IAF flew a total of 550 strike missions against infiltrator positions including bunkers and supply depots. The coordinates of these locations were mostly picked up from about 150 reconnaissance and communications intelligence missions. In addition, 500 missions were flown for air defence and for escorting strike and recce missions.
PAF in a Bind
To prevent the mission from being seen as an escalatory step in the already charged atmosphere, PAF had to lure Indian fighters into its own territory, ie Azad Kashmir or the Northern Areas. That done, a number of issues had to be tackled. What if the enemy aircraft were hit in our territory but fell across, providing a pretext to India as a doubly aggrieved party? What if one of our own aircraft fell, no matter if the exchange was one-to-one (or better)?
Finally, even if we were able to pull off a surprise, would it not be a one-off incident, with the IAF becoming wiser in quick time? The over-arching consideration was the BVR missile capability of IAF fighters which impinged unfavourably on the mission success probability.
While the PAF looked at some offensive options, it had a more pressing defensive issue at hand. The IAFs minor border violations during recce missions were not of grave consequence in so far as no bombing had taken place in our territory; however, the fact that these missions helped the enemy refine its air and artillery targeting, was, to say the least, disconcerting. There were constant reports of our troops on the LOC disturbed to see, or hear, IAF fighters operating with apparent impunity. 
A flight of F-7s was, nonetheless, deployed primarily for point defence of the important garrison town of Skardu as well as the air base.
F-16 CAPs could not have been flown all day long as spares support was limited under the prevailing US sanctions. Random CAPs were resorted to, with a noticeable drop in border violations only as long as the F-16s were on station. There were a few cases of F-16s and Mirage-2000s locking their adversaries with the on-board radars but caution usually prevailed and no close encounters took place.
After one week of CAPs, the F-16 maintenance personnel indicated that war reserve spares were being eaten into and that the activity had to be rationalised, a euphemism for discontinuing it altogether. That an impending war occupied the Air Staffs minds was evident in the decision by the DCAS (Ops) for F-16 CAPs to be discontinued, unless IAF activity became unbearably provocative or threatening. 
Those not aware of the gravity of the F-16 operability problem under sanctions have complained of the PAFs lack of cooperation.
It also must be noted too that other than F-16s, the PAF did not have a capable enough fighter for patrolling, as the minimum requirement in this scenario was an on-board airborne intercept radar, exceptional agility and sufficient staying power. F-7s had reasonably good manoeuvrability but lacked an intercept radar as well as endurance, while the ground attack Mirage-III/5s and A-5s were sitting ducks for the air combat mission.
