News of new developments in the military-industrial complex

American geophysicists have discovered a channel in the atmosphere that transmits sounds for hundreds of kilometers

Waveguides allow you to transmit sound (or light) for a great distance, enclosing them as if in a narrow corridor. One of these waveguides was recently discovered by American researchers after hearing an infrasound from a rocket hundreds of kilometers away from launch. At the Institute of Atmospheric Physics of the Russian Academy of Sciences "Newspaper.Ru" stated that this phenomenon has long been predicted theoretically and its practical benefits are not very great.

Chinese scientists from Nanjing University have found a way to convert lunar soil into carbon dioxide, oxygen and fuel. These works are described in Joule.

Deputy Prime Minister Yuri Borisov said that Russian high-precision weapons are undergoing modernization, including Kalibr cruise missiles and the Kinzhal hypersonic complex.

The newest EPF 16 expeditionary transport ship of the US Navy will be built by Austal USA. The corresponding contract in the amount of $ 230.5 million was signed recently. Now the company will be engaged in detailed design, and then the construction of the ship.

The Russian army used the latest automotive equipment, including the Ural-63706, also known as Tornado-U, in a special operation against the formations of Ukrainian nationalists.

For the first time, such an all-wheel drive three-axle all-terrain vehicle was demonstrated just two years ago, at the International Military-Technical Forum "Army" held in the Patriot Park near Moscow.

The long-suffering Space Launch System rocket with the Orion spacecraft was transported from the launch pad to the vertical assembly building a week and a half ago. It was planned that the entire system would be inspected once again and the shortcomings that prevented the general rehearsal of the launch would be eliminated. However, during the preparation for the repair, suspicious garbage was found, because of which the re-attempt of the final tests is postponed.

Armored vehicles K-43269, also known as "Shot", take part in a special operation in Ukraine. Previously, such equipment has already been tested in battles against gangs of international terrorists in Syria.

The economic war that began this year may last at least decades and raises the question: what do we fly? The "Dry Superjet" is too small and depends on imported parts. The MS-21 is difficult to quickly launch into a series, but at the same time it is promising. The Tu-204 is too voracious. In addition, all these Russian devices — as well as foreign ones — have fundamentally irremediable problems with the high price of flights. Will Russia decide on really radical steps in the development of the local aviation industry? Naked Science will try to understand this issue.

Roscosmos, in a Victory Day video presented to RIA Novosti, openly announced for the first time that its work is far from being limited to the launch of Soyuz and the International Space Station (ISS): the state corporation acts as one of the key segments of the defense industry, the manufacturer of Sarmats, Poplars and Iskanders.

The Presidium of the Scientific and Technical Council of Roscosmos will discuss with the Council of the Russian Academy of Sciences on Space the option of the inclination of the orbit of the Russian Orbital Service Station (ROSS) on May 26, the head of the state corporation Dmitry Rogozin said.

The head of Roscosmos, Dmitry Rogozin, said that the state corporation had begun to conduct mobilization training to accelerate the production of military products.

Apparently, the development of the long-suffering main competitor "Dragon" SpaceX is coming to the final stage. In less than two weeks, the CST-100 Starliner will embark on its second and final test flight. Boeing representatives assured that all the shortcomings identified during the previous test mission (unsuccessful) have been eliminated.

On May 6, 2022, the Naval Systems Command of the United States Navy (NAVSEA) announced that on April 28, baptismal ceremonies and launching of the first prototype of the promising large autonomous uninhabited underwater vehicle Orca XLUUV (Extra Large Unmanned Underwater Vehicle) took place on the Pacific Coast of the United States in Huntington Beach (California). The device was designed and built for the US Navy under the head role of Boeing Corporation, the subcontractor in the construction was the shipbuilding corporation Huntington Ingalls Industries (HII).

On May 6, 2022, Polish Minister of National Defense Mariusz Blaszczak approved a contract for the purchase by the Armament Agency (Agencję Uzbrojenia) from the Polish company WB Electronics S.A. (as part of the WB Group) of the first four battery sets (modules) of the new Gladius unmanned reconnaissance and strike complex for the artillery of the Polish Army. These kits should be delivered already in 2022 to the artillery regiments of the Polish army stationed in the eastern part of Poland. The contract includes an option for an undisclosed number of additional complexes.

British defense concern BAE Systems has introduced a compact HUD display LiteWave, which can be installed in the cockpit of almost any civilian or military aircraft. Modest dimensions (70% smaller than a conventional HUD helmet) allow it to be installed even in very small cabins. LiteWave is also easier to maintain and will cost customers much cheaper.

MIET scientists have improved the system of automated control of parachute platforms for cargo delivery to hard-to-reach areas.

As part of the diversification of production and an increase in the share of civilian products, JSC Obukhov Plant, part of the Almaz-Antey Concern of East Kazakhstan Region, is starting to manufacture industrial additive equipment.

Roscosmos has signed a contract with the Rocket and Space Corporation (RSC) Energia to develop a draft design of the Russian Orbital Service Station (ROSS) for 2.7 billion rubles, follows from the data of the public procurement portal.

Russian scientists from Tomsk Polytechnic University (TPU) have developed the first Russian-made 3D printer for printing in space in microgravity. This is reported by "Gazeta.<url>" with reference to the press service of the university.

Specialists of JSC "NIIgrafit" (part of the scientific division of the State Corporation "Rosatom" - JSC "Science and Innovation") were the first in Russia to develop a composite paste from domestic raw materials for 3D printing of silicon carbide ceramics, including bearings and impellers of pumps for advanced nuclear reactors.
