When you say combat, what exactly are you referring to here? Why do you think the aerodynamics of the RQ, do not allow it to perform combat role such as BVRAA or Air to ground roles? These will be the main role of such a system. I don't see any limitation in the aerodynamics of the RQ. These stealthy UAVs all share similar layout.
Let's put it like this, it's like installing iOS on an android device.
The device is perfectly capable of running iOS, but it was never meant for that, and could very well run into major issues.
Same way here, while the rq170 is capable of being used in combat roles, it's list of munitions it can carry, and how much is limited due to the fact it is primarily used as a spy drone.
Another example is attack air to air missiles on a predator drone, it's technically able to, but it was never designed for it. The one time this was tried (during the us invasion of iraq), it was shot down quite quickly.
This is conjecture. We simply do not even enough information regarding the RQ-170 to comment on its stealth characteristics.
Conjecture is used when there is publicly available information. I'm using what we do know.
Even modern UAV's are prone to such a thing, its means little to be honest. It's one of the achilles heel of UAVs at this time.
I think we should clarify something here, when you say modern, you mean current generation, right?
In that case, the drone being proposed is a next gen drone.
What's important is for Pakistan to start getting into the mindset of mass making UAVs. In Iran for example, even universities make UAVs. It does not matter what level you start at, get enough people and industries involved, and that will greatly help.
Pakistan has been lagging behind. It has the Burraq UCAV, and the licence produced Falco, but other than that, it is far behind nations like Iran, Turkey, and Israel, even though Pakistan has a far greater need for it than the three mentioned.
