ARRW hypersonic missile progress is not ideal, the US military will not consider purchasing next year

The AGM-183A hypersonic missile developed by the U.S. Air Force and Lockheed Martin failed three test launches last year. More testing means the missile has a very low chance of entering service next year.

The AGM-183A Air-launched Rapid Response Weapon (ARRW) is a hypersonic missile jointly developed by the U.S. Air Force and Lockheed Martin in 2018. It adopts a gliding projectile design.

The ARRW is expected to have a range of 1,600 kilometers, a maximum speed of more than Mach 20 per hour, and can be mounted on bombers and fighter-bombers such as the B-1B, B-52H and F-15E.

However, unlike the Common Glide Body (C-HGB) jointly developed by the Army and Navy, the ARRW body was directly tested in combination with the launcher during development. C-HGB is a more robust separation of the glide body from the propellant rocket. Therefore, the technical challenges facing ARRW are relatively complex.

Because of the failure of three test launches in May, July and December last year, the plan to purchase the first 12 ARRWs at $161 million this year cannot be implemented. Therefore, in next year’s budget, the US Air Force only allocates 46.6 million US dollars are used for R&D expenses.

Although Deputy Secretary of the Air Force Gina Ortiz Jones pointed out in response to the media interview that the Air Force will continue with the ARRW and the Scramjet-based Hypersonic Attack Cruise Missile (Hypersonic Attack Cruise Missile) two programs, but the Air Force Secretary Kendall (Frank Kendall) has recently expressed doubts about the ARRW program.

Compared with the relatively smooth development of the Army and Navy C-HGB program, the Air Force ARRW is bound to have a successful test launch this year in order to avoid the entire weapons program from being aborted.

“Ghost Bat” leaves factory, Boeing loyal wingman program enters mass production test stage

The AI ​​loyal wingman program developed by Boeing recently held a naming ceremony at the Queensland factory in Australia, officially numbered MQ-28A, and named after the local native species “ghost bat”. It is also the first military aircraft produced in Australia after World War II. aircraft.

The Loyal Wingman program is an AI combat unmanned aerial vehicle (UCAV) funded by Australia and developed in cooperation with Boeing. The fuselage is 11.6 meters long and has a maximum range of 3,700 kilometers. The /A-18 two-seat model is used for attack. After receiving the command from the captain, the AI ​​system in the aircraft can control the flight route and combat mode by itself.

Boeing’s Loyalty Wingman program, which took just over three years from the concept development stage to the naming ceremony, progressed fairly quickly, and the ceremony at the Amberly Royal Air Force Base in Queensland was based on local natives. Species, the Australian false vampire bat (Macroderma) nicknamed “Ghost Bat” named MQ-28A.

The factory naming ceremony of the ghost bat, in addition to representing Australia’s first development and assembly of military aircraft since World War II, also means that the MQ-28A has officially left the experimental stage and entered mass production testing, one step closer to official service and entering the international market.

“The choice of the name ghost bat not only represents the significance of Australian production, but also because this bat has always been known for collective reconnaissance and hunting, which fully reflects the type of MQ-28A missions in the future.” Boeing Australia program director Glen Ferguson said, after The team will continue to enhance the MQ-28A’s radar, detection systems and AI mission capabilities to meet the needs of the Australian Air Force.

MQ-28A has more than 35 local third-party manufacturers in Australia. It is an important revitalization plan for the local aerospace industry. It also represents that the Australian government will play a more active role than ever under the US Indo-Pacific strategy.

In addition to sending Ukraine’s star pattern, the United Kingdom will deploy the Tianjian air defense system in Poland

Three weeks after the start of the war between Russia and Ukraine, the United Kingdom is one of the largest arms supporters in Ukraine other than the United States. In addition to last week’s announcement to support 100 sets of star-patterned shoulder-launched air defense missiles, it also recently announced that it will deploy the newly developed Tianjian air defense system in Poland to reduce Allied air defense burden.

In response to Ukrainian President Volodymyr Zelensky’s repeated calls for NATO allies to continue to support air defense weapons systems, British Defense Minister Ben Wallace handed over the latest air defense weapons to Poland and Ukraine within two weeks to help the front line resist Russian air threats.

The star-patterned missile was launched by Thales Air Defence in Northern Ireland in 1997. It can be launched by a single soldier shoulder-launched, vehicle-launched or ground-mounted in three modes. The body is 1.4 meters, diameter 13 cm, Weight 14 kg.

The star pattern adopts two-stage rocket propulsion. After the second stage rocket starts, the maximum speed can reach Mach 3.5 per hour, which is faster than the American Stinger missile, the Chinese Hongying 6 (HN-6) and the Russian needle 1 (Igla-1). 1) The 2.2~2.5 Mach height is currently the fastest individual air defense missile system in the world.

The star pattern is the same as similar products in other countries. It adopts semi-automatic guidance within the line of sight. After the missile is launched, the shooter needs to keep the sight at the target to guide the missile. Therefore, the faster the missile, the shorter the exposure time of the launch crew.

Sky Sabre is a land-based version of the Common Air Defense Modular Missile (CAMM) developed by MBDA’s British and Italian branches. The CAMM sea-based version of the Sea Ceptor entered service in 2018, the first mass-produced land-based missile. The Sky Sabre only entered service with the British Army in December last year.

CAMM is divided into general version and Zengcheng version (ER), the projectile length is 3.2~4.2 meters, the diameter is 16.6~19 cm, the weight is 99~160 kg, the maximum range is 25~45 kilometers, and the maximum speed is up to Mach 4. It adopts active radar guidance. It belongs to the latest generation of anti-aircraft missile systems.

After the outbreak of the Russian-Ukrainian war, Poland not only accepted a large number of refugees, but also the border is not far from the big city of Lviv in western Ukraine. The Russian air strikes on the Ussi region have also greatly increased the pressure on Poland’s air defense, so NATO allies are required to support the air defense system.

Although NATO insisted not to set up a no-fly zone in Ukraine’s airspace to avoid a head-on conflict with Russia, the support of a large number of anti-aircraft missiles also put the Russian Air Force and Army helicopters at great threat. Complete air supremacy gives Ukrainian guerrilla action more space.
