The Missile Defense Agency (MDA) lost twenty percent of their budget in 2010 which was a blow to Huntsville, AL. Their formally premier program of basing missiles in Alaska to protect the United States was halted and their focus shifted to sea based systems. Canceling installation of a radar and missiles in Eastern Europe upset the Poles and Czechs as well. Don't worry though, we can make ourselves a new logo. It is on the top of MDA's public homepage, here.
There are also some pointing out its similarity to the Obama Presidential Campaign logo -- so great minds think alike in logo design, I guess.
