Washington conducts security measures in The Black Sea region after Russian jets' attacks
Two of the world's most advanced warplanes have touched down in Romania for the first time, near the shores of the Black Sea and just a short hop from Ukraine, the Crimean Peninsula and Russia.
The United States sent the F-22 Raptors to southeastern Europe two weeks after Russian fighter jets buzzed an American warship in the Baltic Sea.
Officially it was for a NATO training exercise, part of the Rapid Response program showcasing how effectively and quickly U.S. fighter jets, crews and support can be moved to a forward operating base.
The F-22s are known for speed and stealth.
But it was also a show of strength for NATO allies on the Black Sea, where Russia is rapidly building up its military hardware.
The F-22s are known for speed and stealth -- able to travel at twice the speed of sound and hard to spot on radar.
