I don't think any government has funded that much on R&D tbh. Most of the project throughout history of DRDO end up becoming internal projects. Even AMCA was one..This has been the issue since a long time. Every successive governments promise to increase the R&D budget of DRDO yet they only do some minor 2-3% increament at best. Let us not get into that it boils my blood and brings a bit of frustration. All our governments have been chindi when it comes to indigenous product development. The only difference is approach towards foreign system.
