Well since it’s based of the p800 and the full fat version of that is 600km the brahmos would be around the same. I don’t believe Russia would give the tech of giving India the ability to build India a long range variant of the brahmos. Remember what the mtcr is. It prevents the sale of missiles and technology that would allow a country to have a missile with a range of more than 300km and a warhead weight of 500kg. You can buy tech for missiles with in mtcr reg’s but not above. If you want to go long range you must do it on your own or get third party components with in mtcr regs and work on improving it so it can be supported to make longer range missile. Also do note it not about having the longer range missile. You may as well have a penis measuring contest and see whose is bigger. What the mtcr allows is for India to purchase parts that would make their missiles more robust and sophisticated. Personally if you want my take on it won’t bring much to India as India is making their own stuff the luxury of the mtcr would be to acquire kit that India can’t build.
Now since this is a Pakistani forum I shall drag them into this as well here. And they.......... don’t really care.
Why???.... They can buy them of the shelf and is able to modify them to their needs. They have china, mectron and denel who have deep history with Pakistan. They can go into a joint development in with them and share tech on standard aam's or agm's and it won’t violate the mtcr kind of like what India did with the brahmos. Denel has the marlin bvraam which is a good contender to buy parts of from. They can buy the active radar seeker or the dual pulse motor. And no one will be able to complain. Why? If they said it out loud countries (obviously India) will complain, but if kept quiet then no one is the wiser and its happy days. For both parties and nothing was violated. but Pakistan being the country what it is will only make wont it can’t buy (
@Oscar makes that very clear) and if it can buy missiles and they do not like it they can change it. Possibly violating the mtcr in the process.
