This shit is not flying before 2033.Let's see now , the CCS approval for the Ghatak is expected to come in this FY. That's no guarantee for the funds being released but assuming it is , the prototype will take 3 years to be ready for Taxi & Flight Trials.
Moreover the power plant - the KDE is yet to be certified. Neither have we procured an FTB nor is the LCA Mk-1 LSP variant which was requisitioned by DRDO from IAF been allotted for testing or is there any news of the KDE being flight tested & certified on board a Russian FTB though I doubt this can be done for the process itself will be time consuming .
So news about the Ghatak already being fabricated aside ( I'd take such news with a fistful of salt given I've personally seen reports of the AMCA prototype undergoing metal cutting in 2022 - the golden year of Indian defence where a lot was predicted to happen & till date nothing has come out of it or the prediction ) , where's the power plant ?
Assuming through some miracle ADE , DRDO & IAF do manage to get it flying on board the LCA Mk-1 LSP variant , I suspect the testing & certification ought to take anywhere between 3-5 years . If this process begins in 2027 we can expect certification between 2030-32 .
Add another 4-5 years for flying & certification of the Ghatak post that as the entire system has to be validated which means testing it against various parameters including opening up of the flight envelope.
One more important point - since this is the first time we'd be testing both - the indigenous power plant : the KDE & a stealth UCAV we don't have any previous parameters to go by . So expect the testing to be that much more time consuming & laborious .
God forbid it there are glitches then time taken to rectify it will have to be factored in . Once it is certified comes our famed paperwork & negotiations for a contract.
In short don't expect the Ghatak to go in for mass production before 2040 at the very least.

By that time porkis will get their hands on Turkish & Chinese flying wing.
Both amca & ghatak are turning out to be a even bigger clown project than tejas.
