Should We Put Small Strakes and Vortex Flow Tabs on the Upper Wings of Stealth UAVs?
Up until now, most of the adversaries that the US military, and CIA have been flying their drones against do not have the anti-aircraft missiles needed to shoot them down. This is good for us, especially considering the tens of millions of dollars that these UAVs or unmanned aerial vehicles cost the US taxpayer. However, I would submit to you that in the future that will all change.
