It is indeed add a punch to JFT if news is true, no doubt about that. It is a great addition indeed.
It will rather be used against stationary land targets such as radar stations etc than moving sea targets which need greater accuracy. Diffcult to intecept since it is launched from air and the tragectory is different.
But it is not a game changer. Can't compare with Brahmos since it si quite different from this weapon system.
But, it is not a 'game changer'
Not in the traditional meaning, but as a stand-off weapon that is difficult to intercept and gives a higher guarantee of a hit. It puts pressure on the Indian ADGE. Given that the aircraft that is to equip a large section of the PAF , it does change the equation to a certain extent.
After all, Brahmos enjoyed a certain edge over any system employed particularly due to its high speed which made it difficult for SAM's or AAA to bring it down. Here is a weapon that balances that ability out.
However, unlike the Brahmos this weapon has less growth capability beyond its current form. Unless the Chinese can come up with a sea launched version. Its destined to remain a stand-off weapon that will have a restricted range and possibly restricted launch parameters.
