Thanks for the breakdown! Glad to see that opens up private (or DRDO/PSU) SPHs for the next round. And potentially 814 order for MGS.There were separate requirement for 814 MGS, then 200 Tracked SPH and 180 wheeled SPH.
The 180 wheeled SPH plan got shelved. And possibly added onto the tracked SPH.
Further the 200 SPH didn't account for systems along LAC. Therefore an additional 100 or so pieces. Add the 40 shleved arjun based catapults.
That's nearly 520 peices of tracked SPH, exactly what the Army is trying to get K9s of.
The 814 truck mounted howitzers are a separate requirement, not affected by tracked acquisition.
