According to the views of the former head scientist USAF Mark Lewis (Mark Lewis), after the era of stealth comes brand new era, which will become part of hypersonic speed, Defense News reported on September 17.
«The United States have some tremendous advantages compared with other countries, including of cosmic and stealth technology,» said Lewis. Hypersonic speed promising tools, even when detecting radar network, the enemy will not leave time to take countermeasures, said the scientist.
Hypersonic weapon of the future can be created on the basis of X-missile technologies 51A WaveRider. Booster accelerates hypersonic platform up to speed more 4M, then the platform is separated from the RN, cut one scramjet (supersonic-jet engine), by which theoretically reach speeds of more than 6M (about 4,000 miles per hour, or 7,400 km / h) . For example, the Tomahawk cruise missile has a speed of only about 500 miles per hour (880 km / h).
X-51 is designed to reset with underwing pylons bombers B-52, but with a reduction in future versions can be located in the compartments of armament F-22 fighter or bomber developed distant. Prospective gun, weighing about 4,000 pounds (1,800 kg) and a range of 400 nautical miles (740 km) will be incredibly effective for overcoming enemy air and missile defense. There were four tests (two successful and two unsuccessful), the last time the X-51 has a top speed of 5.1 M in a few minutes.
But at the same time hypersonic weapon hardly one hundred percent will change stealth technology. «I do not think it will change stealth, most likely, it will complement stealth. It will be a combination of abilities. This is the direction in which the Air Force will develop, «said Lewis.
According to the views of a leading researcher at the Carnegie Endowment James Acton (James Acton), speed and stealth will be designed to perform 2-various missions. «I do not know what is best in 20-30 years to overcome enemy defenses — stealth or speed. This is a very important question that you must have to reflect reality. There was a time when defense spending was enough to explore all possible ways of development of weapons. But in times of austerity, it is necessary to assign a value to an instrument that will possess the minimum technological risk, «said the expert.
Acton is the creator of a lot of research on ordinary weapons frisky Global Strike (Conventional Prompt Global Strike — CPGS), which is also one of the options for overcoming strong defense / defense of the enemy. Creating a non-nuclear weapon with a large range of their own concept looks a routine task, but in practice is at a technical level complex process. These systems are designed with guns in 2003, and should be taken into service since the 2020s. At the theoretical level instrument frisky global impact quite suitable for implementation by countries with large areas, such as China. But taking into account the higher price of this gun, they will not be used for destruction, for example, anti-aircraft missiles, will be used against them KR type Tomahawk. It will not be perfect against mobile targets.
Their targets will be the main enemy targets such as command and detectability of the system, which comprise base control of the armed forces. «Conventional long-range missiles are part of the global strike weapon, not the best means to defeat mobile / moving targets, such as missile launchers, or fortified underground targets. This expensive instrument. For limited strikes on appropriate goals they can become perfect tool, as well as for the conduct of the air campaign against the harsh strong defense / defense, coupled with the enemy missiles penetrating type shock, «writes analyst at the Center for Strategic and budget estimates Ganzinger Mark (Mark Gunzinger).
Destruction of the enemy’s strong defense is unlikely to be achieved in only one class implements may be useful complement each other a number of technologies that can adapt to different situations. «Different tasks require the introduction of various types of weapons,» said Acton. He also said that the Pentagon must conduct a full-scale study of the effectiveness of different kinds of promising arms in accordance with the scenarios of danger.
