The United States Department of defense applied for additional funds to supplement the two major projects are used to deal with China and Russia.

The U.S. Navy says there is a shortage of sonar buoys for detecting submarines because of increased Russian submarine activity in the Mediterranean and around Europe. So the Navy asked Congress in the Pentagon's comprehensive funding package for Congress to adjust $20 million to buy more detectors. The Navy says there is a shortage of airborne buoys capable of detecting diesel electric submarines and transmitting their positions in real time. In fact, all types / Models / series of buoys have experienced considerable consumption due to anticipated high-intensity anti-submarine activities in 2017.

While the U. S. Navy submitted the application, the United States and European allies alerts the high intensity activities of Russian submarines in the North Atlantic and the Mediterranean region. In support of Syria's operations, Russian submarines fired missiles at targets in Syria. According to media reports, American, British and Russian submarines have been "fighting" in the Mediterranean over the past few years. Applications for the navy have made it clear that the commanders in the region have attached great importance to the Russian cruises. Early July, during the "energy mongoose" exercise, ships, aircraft and personnel from 10 NATO countries conducted a drill in the coastal waters of Norway to search for mute submarines, which was the signal of NATO's attention to the Russian underwater war.

The comprehensive funding package includes tens of millions of dollars for accelerating R & D and deployment of hypersonic technology. Given the progress made in this area by China and Russia, Pentagon leaders have publicly declared that hypersonic technology is an important priority. The new funding for the application includes $20 million to speed up the air force's hypersonic conventional air - launched gliding weapon, which is expected to complete the flight test in 2020; it also includes $65 million to speed up a demonstration of a land launch version.

In April, the Air Force awarded Lockheed Martin's $1 billion hypersonic cruise missile contract to boost this critical capability. In addition to the hypersonic conventional strike weapon program, the US Air Force also collaborated with DARPA and Raytheon to launch a tactical boost gliding project, which was planned to get a prototype in 2023.

The development of hypersonic weapons is also the top priority of Michael Griffin, Deputy Defense Secretary for research and engineering. He said hypersonic "is an advantage that can't be compromised" and said "it will speed up the pace of testing and start delivering capacity in the early 2020s."
