Northrop Grumman 

Hello Sarah! I've edited the controversy section you added to Northrop Grumman a bit. First of all, I think it was a great addition, that really helped improve the article - a company like Northrop Grumman should definitely have a controversy section. But I thought the critisism was a little bit too heavy in places, and some POV shone through. So I edited it, hopefully making it somewhat more neutral. Please take a look.
