Re: UAVs, Drones, Remote Surveillance Tech

Well to be honest, 'educated' or otherwise, most people simply don't know the circus of the public procurement system. I myself didn't until I became part of it. The other major problem i...

I think the article is misleading. There is a reason why you may want to fill up the missiles with water and that is to prevent the missiles from buckling under the payload weight when they themselves are empty of weight/fuel. The reason the missiles are empty of fuel is because they couldn't make ...

Thanks for confirming my assessment. Converting technical capabilities to indigenous subsystems requires a national mission.
