India's mainstay offensive weapon against Pakistan's frontline positions and aerial defense infrastructure comprises a combination of SU-30 MKI paired with a hypersonic Brahmos missile.
The age old dilemma of hypersonic missiles is that of speed vs. manoeuvrability. At hypersonic speeds, the missile does not have the luxury of deviating drastically from final trajectory if it is to have a reasonable level of accuracy. Classically, counter-measures have exploited this to propose relatively simple, linear attack patterns.

Here, we propose that MLRS type weapons are a very effective platform for the sequential launch of projectiles against incoming hypersonic threats such as Brahmos.
It is then significant, that the recent yearbook by MoDP lists MLRS as one of the systems in which Pakistan seeks to build indigenous capability.

b. Production and indigenous development of Rockets MLRS
d. Indigenous development of advanced MLRS
The indigenous production of guided MLRS rockets would be a significant step for Pakistan. Although it is tactically advantageous in its own right, but when seen in the light of defending against Brahmos, such a project takes on a vital importance for national security. Coupled with shoot and scoot type of launch vehicles, these systems would be a potent response to Brahmos, and could spell significant headaches for Indian plans in the future.
We end this article on a forward looking note. Once railgun technology matures to a point that it can be deployed easily on land based systems, it should be expected that Pakistan will invest in procuring this technology for its defence needs. Crucial projects to watch in this regard would be the Turkish and Chinese railgun systems that are currently under development.
