In February 2021, Progress Rocket and Space Center (Samara, part of Roscosmos) completed welding the first stage oxidizer half-tank assembly for the experimental Soyuz-5 perspective launch vehicle.

Structurally, the half-tank consists of a lower bottom, four cylindrical shells with a diameter of 4,100 mm and a technological shell. This assembly is necessary to confirm the ‘O’ tank lower part strength characteristics. The tests will confirm the characteristics of the design documentation.

Currently, the specialists of the testing section of the aggregate-welding-assembly shop are preparing the Soyuz-5 half-tank for strength and tightness tests.

  Light combat Yak-130M
  The presentation of the Ya-130M aircraft took place at the international military-technical forum "Army-2024", which was held from August 12 to 14, 2024 at the Patriot Convention and Exhibition Center. It should be noted right away that this is not just the modernization of the Yak-130 aircraft, but the transformation of a combat training aircraft into a full-fledged light combat aircraft. In the information field, this event was marked by a number of brief reports from federal news agencies. But the project, like the Yak-130 aircraft with its unique flight characteristics, deserves a more detailed review, which we decided to do.
