With the improvement of equipment information, unlike the original blind technology stacking, installing phased array radar for aircraft carriers now seems to have become a necessary "retro style". However, with Britain and Russia, phased array radar will be deployed. It is different on the bridge, whether it is the original "Enterprise" or the latest "Ford" class aircraft carrier. They have a phased array radar under the bridge to ensure that the bridge has sufficient height. This layout of U. S. aircraft carrier bridges will limit the detection range of phased array radar, but the United States, the world's leading carrier, knows which phased array radar and bridge are more important. According to this text, the following statements are incorrect:. ['At the height of the bridge, there is a certain gap between Britain, Russia, and the United States.', 'Britain, Russia, and the United States attach importance to deploying phased array radar on aircraft carriers.', 'The U. S. Navy does not pay much attention to the actual combat effectiveness of aircraft carriers.', 'Phased array radar is more reasonable to deploy under the bridge than above.']
