Joint Assault Bridge

The Joint Assault Bridge (JAB) is a combat engineering vehicle designed to provide gap-crossing capabilities for armored and mechanized forces. It is built on the M1 Abrams tank chassis and is capable of launching and retrieving a 60-foot (18-meter) 'scissor' bridge.

The Joint Assault Bridge was developed by Leonardo DRS to replace the aging Vietnam-era M60-based Armored Vehicle Launched Bridge and the cancelled XM104 Wolverine program. Following rigorous testing, the system entered low-rate initial production in 2016 and was officially approved for full-rate production in 2021 to equip US Army and Marine Corps combat engineer units. While yet to see extensive large-scale combat, the vehicle has been deployed to forward-stationed units in Europe and the Indo-Pacific to support joint-force mobility and NATO deterrence exercises. Today, the M1074 JAB remains in active production and fielding, serving as a critical modernization pillar for heavy brigade combat teams by ensuring armored forces can rapidly cross wet or dry gaps under fire.
