The DRDO Sarvatra (Everywhere) [1] also known as Sarvatra Multi-span Mobile Bridge System is a truck-mounted, multi-span, mobile bridging system developed by Armament and Combat Engineering Systems (ACE) and Research and Development Establishment (R&DE) Engineers of Defence Research and Development Organisation (DRDO) [2] for the Indian army. Its production public company is Bharat Earth Movers Limited (BEML), Bangalore.

Design

The Sarvatra is a 75-meter, multi-span, mobile bridging system consisting of five scissor bridges made of aluminum alloy with a span of 15 meters, each mounted on a separate mobile platform. Each mobile platform is a modified Tatra T-815 VVN 8 x 8 chassis, drivable from both ends from a small cabin with required driving controls. Further, a microprocessor based control system is utilised to deploy and operationalise the system in less than 2.5 hours.

When the scissors bridge is opened, it is fitted with adjustable trestles to enable multiple units to be used to bridge wet and dry gaps. Five sections provide a total bridge length of 75 m, and four meters in width. The bridge is launched/recovered from either end. With the help of telescopic legs, the height of the bridge can be adjusted from 2.5 m to 6 m to reduce visibility.

The Sarvatra project was sanctioned in 1994 and completed development in October 1999 at a total cost of ₹230,000,000. It was approved for production in March 2000 after trials. The Sarvatra was to replace the East European PMS Bridges in the Indian army, which requires 57 Tatra vehicles to bridge 100 meters. In contrast, the Sarvatra, with just five sections, bridges 75 meters. At ₹600,000,000 per set, the PMS costs almost three times as much as a Sarvatra.

A 20 m variant of Sarvatra bridge system capable of bridging a gap of 100 meters has also been developed.

HVF was set up in 1961 by the Ordnance Factory Board to manufacture heavy battlefield equipment and was later made part of AVANI during the re-organization in 2021. The factory is powered by a 16 MW solar power plant, spread over 80 acres (32 ha), commissioned in 2018 and installed by Bharat Electronics Limited (BEL) at a cost of 1,050 million (US$13 million). The plant helps reduce carbon dioxide emissions to the extent of 26,000 tonnes per annum, saving 45 million (US$560,000) annually. Products of HVF include Vijayanta, Kartik BLT, M-46 Catapult and T-72 Ajeya, Arjun MBT and T-90 Bhishma tanks.

<span class="mw-page-title-main">Armoured vehicle-launched bridge</span> Military engineering vehicle

An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines, when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located, or sufficiently sturdy, a substantial concern when moving 60-ton tanks.
