3) Northrop Grumman X-47B
Military aircraft aren’t cheap, but if you want to win a war that’s far from your own country you need to be prepared to get over there quick smart and bomb the loving bejeezus out of ’em.
The Northrop Grumman X-47B is still in its testing phase, but what a beast? So far it has cost around $813 million, bargain. The amazing thing about this little space aged craft is that it is unmanned. It can take off from warships, go about its business and then land again without anyone having to sit inside it at all. If you ask me that’s a recipe for disaster. Clever though, huh?
