Agree on the point that we can keep going with equipment that is indigenous but only matches 85-90% of the criteria instead of importing foreign equipment that matches 100%. In fact, we are already doing that in some areas like Tejas, LCH, and others.
However, comparing Predator MQ-9 which is a proven, war-tested platform for decades, packed with the latest sensors and weapons to Tapas BH-02, which is literally still in flying trials trying to reach the desired altitude is too much.
A UAV is not just a flying kite, endurance is not everything. We need sensors, especially high-resolution SAR, secure data link with over-the-horizon communication which is the most important factor, and light PGMs (I think SAAW might work).
Now, DRDO might have already figured all that out, I mean they have already taken a lot of time to develop this basic UAV.
