From what I understand Pakistan's air defence capabilities are somewhat lacking. What I propose Pakistan do is simple, buy more air defense systems comprising Short Range Air Defense (SHORAD) and High to Medium Air Defense (HIMAD). The most likely supplier would be China which would be the best choice in terms of the supply of parts, radars, and associated equipment in conflicts. I know Pakistan has purchased the LY-80 and the FM-90 but the number purchased was insufficient and their engagement ranges aren't very far. The KS-1 SAM is a good missile for Pakistan because of a variant called HQ-22 which has performance comparable to the HQ-9
- HQ-22: The HQ-22 (export version FK-3) is China’s new generation medium-range, radar-guided surface-to-air missile. It is a second-generation variant of the HQ-12, has a range of up to 170km and an effective altitude from 50 m to 27 km. It is relatively cheaper to produce than the HQ-9 and will form one of the mainstays of China’s air defense system, replacing the Cold-War era HQ-22. Command guidance/semi active radar homing guidance.
If Pakistan purchased 10-20 of these spread around the country in strategic positions India would surely suffer aircraft losses that are unacceptable.
If you have any input be sure to tell me.
Now I will talk about SHORAD procurement that I think would do Pakistan good. The Sky Dragon 50 is a SAM developed from the PL-12 air to air missile that is comparable to the NASAMS.
The Sky Dragon 50 uses the DK-10A missile derived from the surface-to-air missile PL-12 series. The DK-10 is derived from SD-10A, and the missile is lengthened with an additional booster stage, which has larger diameter than the original air-to-air missile. SD-10 is the export version of the PL-12. The DK-10A has a range from 3 to 50 km and can be used from altitude of 30 m to 20 km. The missile flies at a velocity of more than 1,000 m/s and is highly maneuverable, with a maximum overload of up to 38 g. To hit the target, the missile uses an inertial guidance system and data-link. The missile has a 20 kg High Explosive (HE) fragmentation warhead. If 20-30 of these systems were purchased an additional defense against Indian aircraft and even if India achieves air superiority they can still be harrased by SAM systems.
For short range air defense on a mobile system I think the Sky Dragon 12 and it looks pretty similar to the Pantsir and would be a good system to purchase for short range air defense. The Sky Dragon is fitted with 12 Tianlong 12/ SD-12/ FK-1000 missiles which is Russian 9M311 missile exported to China in 2005. The 9M311 missile (NATO designation SA-19 Grison) has semi-automatic radar command to line-of-sight guidance, weighs 40kg with a 9kg warhead. It is 2.5m long with a diameter of 1.7m and wingspan of 2.2m. The missile's maximum speed is 900m/s and can engage targets travelling at speeds up to 500m/s. The range of the FK-1000 missile is from 2 to 12 km for and can be used has an altitude from 15 m to 5,000m. This is the missile from the Tunguska.
