Artillery is considered to be single most lethal and widely used tool of battlefield since ages that’s more true in case of modern #artillery systems which are capable of introducing wide range and long distance precise damage to enemy’s camps, Given it’s huge importance in battle field India has not only procured new systems like M777 ultra light #howitzer and K-9 Vajra T from foreign vendor under joint venture with Indian firms, but has also worked in-house to develop multiple #gun systems, more importantly many of them coming from private sectors or through Strategic Partnership Policy between #DRDO and private companies.
105/37mm Indian Field Guns
This gun system is based on Light field guns of UK and was developed by ARDE. The gun produced since 1984 by Gun Carriage Factory, Jabalpur weights around 2.4 tons and can be easily air transported by current Indian MI17V5 helicopters.

Indian Army has concern with weight of ATAGS which is on the higher end of 18 ton as compared to other system around the world which weights around 13-15 tons. So this gun can get attraction of Indian Army however it lacks the burst firing capability of ATAGS. Currently this gun is being tested by Saudi Arabia for its army and recent news suggests it is also entered final testing phase of Indian Army.
155/39mm MARG-T/S
The gun developed by Kalyani strategic Systems ltd as a direct competition to M777 ULH of BAE, US currently being produced under a joint venture with Mahindra. The Titanium version weights only 4.5 tons and is easily deployable in mountain terrain and can also be airlifted using Chinook Helicopter of IAF. The steel version weights 6.8 tons and is cheaper option to titanium version as titanium is costly.

155/45mm Sharang
These are basically 130mm M46 guns of Russian origin which are upgraded by OFB with 155/45mm Sharang kit. Each upgrade costing less than Rs.75 lakh makes it almost a new gun. The upgrade kit include a new 155mm barrel, a new breech block along with hydraulic rammer to ease the loading. It will also feature a new sighting system. Basically cannot be strictly classified as a howitzer but artillery gun system, weighting around 8.5 tons and having elevation of 0 degrees to 45 degrees and traverse 25 degree to left and 25 degree to right. The range has been increased to 39km. Initially up-gunning 180 units was done with help Israeli company Soltam( now Elbit) under Project Karan. But now under new tender OFB is up-gunning 300 units on its own and is suppose to supply them to army by 2022.
