A video clip that has been aired on YouTube since the end of May has been pulled amid security concerns. 

The video, intended to show that women in the US Navy can do the same jobs as men, was filmed aboard an aircraft carrier and could compromise security.
During the video, which also showed a sailor dancing in a radiation suit, the door to the ship's nuclear power plant flashed on to the screen.
Security regulations prohibit pictures of a ship's nuclear plant from being shown to foreigners.
