The satellite box properly exceeds the 3.35 [meters?] limit.
We've seen Volga-Dnepr An-124's deliver satellites in China. Will the grounding effect any upcoming Chinese launches?Discussion (that I'm reading via Google translate) in the 9ifly 2020 "China Satellite Launch Plan and Launched Statistics Post" thread states that some satellites cannot be carried via domestic rail due to width or height clearances.QuoteThe satellite box properly exceeds the 3.35 [meters?] limit.Another member mentions use of the Il-76 for satellite transport. I assume that there are some large satellites that exceed its dimensional capacity?

But the satellite itself is most likely Chinese built.I remember a problem in translation from Russian (I think, or Chinese) of either NPO-PM or Luch.

Volga-Dnepr have now resumed AN-124 operations.https://www.scramble.nl/civil-news/volga-dnepr-resumes-an-124-operations
A smart production line capable of producing 240 small satellites per year has been put into operation in the central Chinese city of Wuhan, according to its owner, a subsidiary of China Aerospace Science and Industry Corporation Limited.
China plans to launch 7 satellites, "Fengyun" in the 2021-2025 years.Beijing, January 19 / Xinhua / -- China plans to launch two weather satellites, Fengyun-4B and Fengyun-3E, in 2021. During the 14th five-year plan (2021-2025), five more Fengyun satellites will also be launched.As the correspondent reported today. Xinhua in the China Meteorological Administration, the Fengyun-4B satellite is actually the first operational satellite of the Fengyun-4 satellite series. The Fengyun-3E weather satellite will become the world's first polar-orbiting satellite for morning and evening monitoring, will fill the current shortage of global meteorological satellite observations and will be able to provide significant support in the development of numerical weather forecasts.
On January 22, my country's first prototype of a 3.35m diameter composite material storage tank was born in the Rocket Academy. The storage tank is mainly used in liquid oxygen environment. Compared with the metal storage tank, it can reduce the weight by 30% and has higher strength. It can greatly improve the structural efficiency and carrying capacity of the rocket. It is a new type of lightweight storage tank. The birth of the prototype of the composite material storage tank marks that my country has broken the foreign monopoly and has become one of the few countries in the world that has the ability to design and manufacture composite material storage tanks.
The density of the composite material is about 1.7g/cm³, the density of the aluminum alloy is 2.8g/cm³, and the density of the aluminum-lithium alloy is 2.7g/cm³. The specific strength of the composite material is 8 times that of aluminum alloy and 6 times that of aluminum-lithium alloy.
The greater the rocket carrying capacity, the relatively large increase in the ability to enter space, opening up a larger stage for China's aerospace. The weight of the tank structure accounts for more than 50% of the total weight of the rocket body structure. Therefore, the lightweight of the tank is one of the important ways to improve the rocket carrying efficiency. Compared with the metal tank used in the liquid hydrogen and liquid oxygen environment, the composite material tank is mainly used in the specific liquid oxygen environment and can be used in the final stage of the rocket. According to data, every 1 kg weight loss of the rocket's final stage tank means an increase of 1 kg in carrying capacity. Moreover, the composite material storage tank has the advantages of fewer production procedures and short cycle. From the perspective of foreign research results, the use of composite material tanks can reduce the overall cost of rockets by 25% compared to metal tanks. In the future, the promotion and application of composite material storage tanks in the final stage of rockets will greatly increase the carrying capacity of the rocket, and will have a profound impact on the exploration of reducing rocket costs.
