미 미사일방어국(Missile Defense Agency), 극초음 미사일 요격체계 개발 추진

본 블로그는 6월”미국 미사일 방어국, 극초음속 활강체(HGV, Hypersonic Glide Vehicle, 극초음속 미사일)요격 미사일 개발 관련 내용 공개”라는 제목의 포스팅을 통해서 미국의 극초음속 미사일 요격 시스템의 개발에 대해서 알린 것이 있지만 이제 그 개발이 더욱 실체화하고 있다고 생각된다.미국의 MDA는 11월 19일, 극초음속 미사일 요격 시스템(GPI, Glide Phase Intercepter)설계 때문에 록히드·마틴(Lockheed Martin), 노스롭·글망(Northrop Grumman), 레이시온·미사일&디펜스(Raytheon Missiles and Defense)의 3개로 각각 계약을 체결했다고 발표했기 때문이다.(아래 기사링크참조)https://www.defensenews.com/pentagon/2021/11/20/heres-the-three-companies-selected-to-design-hypersonic-missile-interceptors-for-mda?fbclid=IwAR1CwVmI8qAqrG4OYKPlW13BTE5nouFMUOI7_Hv4jDk8nqPGzjRdAzdAQXY

It is noteworthy that the GPI design will be promoted on a separate issue from the discussion on the Accelerated Concept Design Phase study, which appears to be aimed at intercepting the boost phase, which has been considered as a conventional hypersonic missile intercept system. However, since this blogger has no clear idea about the Accelerated Concept Design Phase, today’s posting will focus on the concept of GPI.

The reason for this is that it is still at the most likely stage to intercept. The Boost Phase is not easy to intercept in that it strikes deep into enemy territory. This is the same for conventional ballistic missiles, but gliding hypersonic missiles have a shorter acceleration stage than existing ballistic missiles. Ballistic Phase also takes place in a very short period of time, and Direct Re-entry and Pull-Up boot moments also take place in a short period of time. This means that even if the launch of hypersonic missiles is detected by early warning radar or satellites, it is difficult to complete preparatory procedures to intercept the hypersonic missiles. Therefore, unlike long-range ballistic missiles, even hypersonic missiles that fly below the atmosphere should be intercepted by the Glide Phase, which is the mid-course (space) of ballistic missiles. Of course, as explained several times in the image below, gliding hypersonic missiles fly in the atmosphere, so it is difficult to detect them with the air defense radar or early warning radar of NORAD. It will be possible to detect when a hypersonic missile falls toward the U.S. mainland. The reason for this is that it is still at the most likely stage to intercept.

The SM-3 Block IIA missiles can be intercepted in mid-course for IRBM class ballistic missiles and in up-and-down stages for ICBM class ballistic missiles, but hypersonic missiles with ICBM class range over 70 km above the ground may be intercepted in the pre-mid-course stage.

The U.S. military has expressed concern that the U.S. lags behind Russia and China in the hypersonic missile field every day, and the U.S. media has reported it every day, but it is judged that this is not comparable to the Sputnik shock. It is true that Russia is the master of hypersonic missile development and is one step closer to its actual deployment than any other country – they claim to have already deployed it, but I personally find it difficult to fully trust it. This is because the platform for operating the missile itself is still close to incomplete. However, recent reports suggest that the deployment of zircon missiles and Kinzal missiles has gradually become a reality compared to a few years ago. – This can’t be helped. Frankly speaking, the U.S. Department’s intention seems to be mainly to promote to U.S. taxpayers why the U.S. should develop and deploy hypersonic missiles at a huge cost. There is a fact that everyone overlooks, but it is the United States that has the most advanced system to defend itself against enemy missile attacks. The U.S. is building the most advanced missile defense system, and Aegis Ashow and THAAD are deployed or completed in U.S. allies to defend the U.S. mainland, but no other country has built such a missile defense system. (Japan’s Aegis Ashow, Poland’s Aegis Ashow, and South Korea’s THAAD radar can ultimately be seen as a missile defense system to defend the U.S. mainland.)

Of course, Russia has its own field air defense system and detailed missile defense system with S-400, but it can still be considered a base air defense system because it has only a system to intercept some ballistic and cruise missiles at the end of the day. In other words, it is not a system that neutralizes the U.S. before reaching the U.S. mainland like the U.S., but rather a level that enables the “survival” of retaliation capabilities from enemy attacks. It is hard to say that China has an effective missile defense system against U.S. ballistic missile attacks in the first place.

Regarding China’s missile defense capability, I would like to introduce the comments of Baek Sung-ho, a military expert and a petin who always supports China. The U.S. Department of Defense’s Annual Report to Congress – Military and Security Developments Involving the People’s Republic of China 2019 shows China’s BMD capability. (The reason for placing missiles in western China to intercept IRBM seems to be to be trying to stop missiles flying from India and Russia. アメリカはIRBMを現在持っていませんので、該当事項はありません。)Ballistic Missile Defense (BMD)China is working to develop ballistic missile defenses consisting of exo-atmospheric and endoatmospheric kinetic-energy interceptors. In 2016, official media confirmed China’s intent to move ahead with land- and sea-based midcourse missile defense capabilities. The HQ-19 mid-course interceptor has undergone tests to verify its capability against 3,000 km-class ballistic missiles, and an HQ-19 unit may have begun preliminary operations in western China. Indigenous radars including the JY-27A and JL-1A – the latter advertised as capable of precision tracking of multiple ballistic missiles – reportedly provide target detection for the system.The PLA’s long-range SAM inventory also offers a limited capability against ballistic missiles. China’s domestic CSA-9 (HQ-9) longrange SAM system likely has a limited capability to provide point defense against tactical ballistic missiles. China has fielded SA-20 (S-300 PMU2) SAMs, and its SA-21 (S-400) SAMs may have some capability to engage ballistic missiles, depending on the interceptors and supporting infrastructure.

In conclusion, it can be said that the perception that the U.S. is inferior in competition with small and medium-sized companies over the development of hypersonic missiles in the U.S. stems from the illusion that it does not even consider MD capabilities. In addition, the United States has begun developing an interception system for hypersonic missiles. Competition between the side with only a spear and the side with both a spear and a square back is naturally advantageous for the side with both a spear and a shield. However, the U.S. MD is actually designed to protect major bases deployed in the U.S. mainland and Guam, and although it provides nuclear umbrellas to U.S. arterial countries, it cannot be said that it also provides missile defense. Of course, the deployment of more advanced systems will not be an easy problem in Korea, where THAAD is difficult to deploy. In fact, technically, it is virtually impossible for the U.S. to defend South Korea and Japan against glide boost type hypersonic missile attacks by China and North Korea.
