Edit: Little change in what I said... the field of blue is the American Union Jack. The rattle snake with the "Don't thread on me" with the stripes was the first Navy jack which in 2003 under the Sec of Navy order, all US ships are to fly for the duration of the War on Terror.
Yes, we have a jack (ours is the canton of the US Flag) but the British Navy actually has a flag they fly in addition to the national flag. Civilian vessels fly a different colored ensign.
