The U.S. Navy has more than 10 aircraft carriers. Logically speaking, the U.S. Navy is one of the most powerful navies in the world. However, as powerful as the U.S. Navy is, it still has to hand over aircraft carrier-related technologies to the United Kingdom. Patent fees, the reason why this happens is actually very simple. The first is that the UK is actually the pioneer of aircraft carriers, so it has mastered a lot of aircraft carrier-related technologies, and naturally has a lot of patents. Secondly, although the British Navy has lagged behind, it still has a lot of technical reserves in aircraft carriers, and it also has its own set of ideas when it comes to building aircraft carriers.
First of all, Britain is actually the pioneer of aircraft carriers, so it also has a lot of aircraft carrier-related technologies, and naturally there are many patents. You must know that the first country in the world to begin testing aircraft carriers was the United Kingdom. Before World War I was over, some sharp-eyed people in the British Navy saw the huge role of aircraft in the pattern of naval warfare. Although the aircraft performance of that era was very backward, the United Kingdom still converted many ships into aircraft carriers for service.
Secondly, although the British Navy has fallen behind, the UK still has a lot of technical reserves in aircraft carriers, and it also has its own set of ideas when it comes to building aircraft carriers. This is unmatched by many countries. Since the UK is geographically located as an isolated island in Europe, it attaches great importance to the development of its navy and air force. So even though the UK is now unable to build a more powerful fleet because it has no money, the UK is still very strong in terms of technical reserves for aircraft carriers.
In fact, the UK has developed a lot of aircraft carrier technologies, such as steam ejection technology and the landing assist system, which were all invented by the British. The U.S. Navy pursues pragmatism and believes that British technology is more advanced than its own, so it began to adopt related technologies invented by the British, such as the beveled deck and what the author mentioned before. So it is not difficult to understand why the United States has to pay patent fees to the United Kingdom.
