Any thoughts, comments on the Styker bridge layer?

Pearson Engineering has developed and tested an armoured vehicle-launched bridge (AVLB) for the General Dynamics Land Systems 8x8 Stryker M1132 Engineer Squad Vehicle (ESV).

The baseline Stryker M1132 ESV platform is retained with its roof-mounted remote weapon station (RWS) retracted, while a Pearson Engineering Jettison Fitting Kit is fitted to the front of the hull to support the Bridge Launch Mechanism (BLM).

Four hydraulic cylinders are used to articulate the BLM with hydraulic power being provided directly from the M1132 ESV platform. The BLM enables the crew of the M1132 ESV to launch or recover the one-piece bridge over the front of the vehicle in less than two minutes while remaining under full armour protection.

The 11.58 m long and 4 m wide one-piece bridge - with trackways that are 1.52 m wide - is rated at Military Load Class 50 (MLC 50), weighs 3,000 kg, and can be used to bridge wet or dry gaps up to 10.05 m in span. Pearson Engineering can supply alternative bridges if required.

When launching or recovering the bridge, the foot of the BLM remains in contact with the ground, which reduces the load transfer onto the M1132 ESV launch platform and provides greater stability.

While travelling the bridge is positioned horizontally and secured to the vehicle using a Rear Bridge Support (RBS), which is mounted above the rear troop compartment.

The Stryker M1132 ESV is deployed in large numbers by the US Army's Stryker Brigade Combat Teams (BCT) and the same equipment can be applied to other tracked and wheeled armoured vehicles.

The company has also supplied the US Army with a range of front end attachments (FEA) that enable the vehicle to be rapidly reconfigured in the field to address specific battlefield threats.

The FEA range includes the Pearson Engineering Straight Obstacle Blade (SOB), Surface Clearance Device (SCD), Light Weight Mine Roller (LWMR), Area Clearance Device (ACD), and the Obstacle Marker System (OMS).

That is not a very big bridge, and the MLC is disappointing for mechanized operations.

The launching system would also be a big signature for a watching enemy. 

If we want something to launch a bridge under fire, we are better with a tank platform.  We are not worried about launching under fire, there are plenty of more capable bridges that can be truck launched.
