They both have but in cooperation with foreign partners -
TATA Power SED's 155mm/52-cal Motorised Howitzer developed with South Africa’s DENEL Land Systems is dubbed as 55% indigenous by content. Indian Army has a requirement of 1,800 such Mounted Gun Systems.
The gun itself isnt though. They will start producing the gun eventually some time after they get the contract. And it's hard to say where this Denel partnership will lead if they dont get the Indian contract.
Kalyanis on the other hand have a gun being produced, as they bought out the whole line.
