About your question, you can get the following contents by searching related websites: Unmanned Combat Aircraft (UCAV) is a brand-new air weapon system, and its main function at this stage is air defense suppression and deep attack. In 1990s, the United States brought it into the military equipment development plan for the first time, which attracted great attention from the military circles of various countries and set off a worldwide upsurge of developing UCAV.

In August 2005, the U.S. Department of Defense revised the third edition of the Roadmap for UAV Systems from 2005 to 2030, stipulating that the number of UAVs will reach nearly 2,000 in 2065, with 438+05, and the number of models will increase to more than 20. In addition, India, South Africa and Japan are also actively developing drones and developing different types of unmanned reconnaissance aircraft. The research and development level of Russian military drones is seriously behind that of western countries, and it is planned to introduce "Hermes" and "Heron" drones from Israel.

Through similar literature, it can be concluded that big countries and regional powers, including China, are developing UAVs, but the level is uneven, and some are still in the primary stage. Countries like the United States, Israel, China and Britain have made remarkable achievements.
