UAV technology has matured, and its prospects for spying on business intelligence have also raised concerns. Even if hovering in the air that is not easily detectable by the human eye, the drone camera can still record experiments in the house, or conduct eavesdropping, and even invade the wireless LAN to steal the intranet login password.
According to reports, in order to prevent competitors from sending drones to steal trade secrets, a British car manufacturer installed a laser pointer jamming system at the test site. If you find that an unknown drone is approaching, you can launch a laser beam to its lens to prevent it from shooting normally.
Theodore Birstall, Professor Emeritus of Science, Technology and National Security Policy at the Massachusetts Institute of Technology in Cambridge, said that there is little evidence that the above situation has changed, and this is "a science and technology-related vacuum Policy documents". They worry that the expansion of US missile defense into new areas may stimulate nuclear powers like Russia and China to more actively seek advanced weapons that can resist defense, such as mobile low-flying hypersonic cruise missiles.
Most controversially, the report endorsed the creation of a dense space-based interceptor network. The study found that this idea can be traced back to the administration of former President Ronald Reagan, when it was derided as "Star Wars." Such a system requires deployment and operation of more than 2,000 satellites in low earth orbit, and therefore costs hundreds of billions of dollars.
Laura Grego, a physicist and missile defense expert at the Alliance of Concerned Scientists in Washington, DC, said this would weaponize space and endanger existing space assets. When the Pentagon announced the report, Trump once again made uncautious remarks. He predicted that the space interceptor will eventually become "a very important green laser pointer part of our defense and an important part of our offense."
However, the funding of any plan requires the assistance of legislators. In fiscal year 2018, the Republican-controlled Congress increased the Missile Defense Agency’s budget from $8.5 billion to $11.5 billion. Democrats who now control the House of Representatives are not optimistic about the anti-missile system. Greg predicted that the government’s plan "will face more doubts."
