DF-41 - Road Mobile
DF-41 is solid-fueled road-mobile intercontinental ballistic missile and one of its biggest advantages is its mobility and vitality. There is no point to put it inside a silo. Space technology missiles do not use the chassis of subsidiary companies. Taian and Wanshan are currently testing the super-heavy TEL chassis developed for the Dongfeng 41 missile.
On the rail mobile ICBM issue, US intelligence had not seen the Chinese pursue the rail option. They seemed to like the road option more, and their road infrastructure better suited them for mobility, for more mobile options. They are very concerned about the US ability to find and kill TELs so the roads give more ability to flush out and go to hide sites and get to launch locations.
The 16X16 chassis produced by Wanshan is readily available but needs improvement. Taian is a brand-new research and development company, but Taian's TEL is even higher performance. In addition to Dongfeng 41, the Dongfeng 31B missile also plans to replace the Hanyang HY4330 trailer-mounted launch vehicle with a TEL chassis.
As a road mobile missile system, the Dongfeng-41 intercontinental missile launch vehicle is developed by the 15th Institute of the First Academy of the Aerospace Science and Technology Group and the Taian Special Vehicle Company. The chassis model is HTF5980, including HTF5980A and HTF5980B, which may be launch vehicles and transport vehicles respectively.
The HTF series special vehicle chassis is a new generation of aerospace special vehicle chassis developed on the basis of more than 40 years of experience in the development of special aerospace vehicles and combined with user needs. It uses an integral welded structure frame, oil-gas spring independent suspension, and multi-axle Group steering and multi-axle drive are technical features that highlight the requirements for high mobility. In 2006, the design of the HTF 5980 chassis was completed within 3 months under the collaborative design mode, and the performance analysis of the entire vehicle and key components was completed simultaneously. The HTF5980 (16×10) chassis is the first eight-axis self-propelled chassis in China, equipped with a multi-axis steering system to meet the requirements of high maneuverability.
In recent years, the development of heavy-duty military special chassis in China has benefited from the introduction of technology from the Minsk traction vehicle plant in Belarus. The Minsk Traction Vehicle Plant was formerly known as the Maz (MAZ) of the former Soviet Union and is famous for producing super heavy military chassis. After the Soviet Union disintegrated, it was owned by Belarus. Since then, Russia’s heavy missile chassis has been imported from Belarus for many years. Now Russia is relying on the introduction of Belarusian technology to allow Kamaz to produce 16x16 heavy-duty chassis and prepare it as a launch vehicle for Yales and Baiyang ballistic missiles. However, the KAMAZ-7850 prototype developed by Kamaz on the basis of MZKT-79221 interrupted the shaft a few months ago, and the development progress was blocked, while Europe and the United States did not have the same type of chassis.
The 8-axis special vehicle chassis technology room has the world’s highest technology for missile TEL vehicles. Currently, only Belarus, Russia and China have mastered this technology. Such vehicles have extremely stringent requirements for integrated transmission and suspension systems. Currently, only Belarus Minsk Tractor Company has fully mastered this technology. Even at present, China had not fully mastered the comprehensive transmission and suspension system of 8-axle super-large special vehicles, and some technical difficulties are still in the state of technological research. As can be seen from the pictures, the missile launch vehicle chassis of the Dongfeng-41 missile is much lower than that of the Russian "Topol" M and "Yars" missiles. It overcomes the problem of the high center of gravity of the MAZ792 series chassis. The design of the Taian special vehicle is obviously The design of the Belarusian counterparts has undergone quite different changes, and these changes are the new 8-axis TEL cars developed by the Chinese in their own design style.
