US have always been known for its advanced technology. They are the same country who for the first time used nuclear bombs in this whole world practically. But I am here to talk about something else. I am going to talk about Stealth technology of US. It is one of the most superior technology ever made. This technology is alo known as Low Observability Technology. It is a sub discipline of electronic countermeasures which covers a range of technology utilised with aircraft, ships and missiles. Stealth has made their force more stronger. Just think that that you dont know that from where your enemy is attacking then what will you do. Stealth is skilled in doing this. All I can say that the pace with which america is advancing its very true to say that they are the biggest power of the world.
