MOSCOW, March 14. /TASS/. The Russian Defense Ministry jointly with domestic defense contractors is developing demountable auto bridges invisible for the potential enemy's detection systems, Deputy Defense Minister Dmitry Bulgakov said on Monday.

"The bridges must be invisible for [the enemy’s] modern detection means to raise the survivability of bridge-crossing," he said.

According to Bulgakov, the new structures are being developed of composite and other innovation materials to facilitate the bridges’ assembly and reduce their weight while the carrying capacity and the length of the bridge spans will be increased.

The costs of maintaining these bridges will be lower while their service life will be longer, the deputy defense minister said.

Russian industrial enterprises are carrying R&D to improve the operational characteristics of demountable auto bridges without attracting state budget funds, the deputy defense minister said.

Specialists of the Khrulev Military Logistics Academy will also be involved in the effort to create stealth bridges, the deputy defense minister said.
