Polaris Defense debuted a modified MRZR-D4 high-mobility tactical vehicle at DSEI 2017 in London.
Speaking to Jane’s , John Olson, the company's vice-president and general manager, explained that Polaris’ UK business component led the development of the platform, the design of which enables the rear seats to be removed to accommodate an extended, two-level cargo bed that increases the payload capacity.
The modifications were in part driven by requirements from the UK’s Army Warfighting Experiment 2017 (AWE 17) that included increased capacity. AWE 17 culminated in March with a four-week live testing and experimentation period on Salisbury Plain Training Area (SPTA).
Olson said the two-level design is also intended to provide personnel with better access to equipment and improve how it is loaded and stowed.
Further features include SFC Energy’s EMILY 3000 methanol fuel cell, which according to Olson is able to recharge and support the power requirements of a unit’s batteries for 21 days and is covert, having minimal noise and heat signatures; the only bi-product form the operation of the fuel cell is water.
A number of tactical capabilities have been trialled recently, Olson said, including at Fort Benning, Georgia, where the ability to sling-load a single DAGOR or two MRZR vehicles – in both cases with full combat loadouts – under a UH-60 Black Hawk helicopter was proven. This effort was driven by US Army requirements, Olson said.
Elsewhere, Olson said the company’s DAGOR vehicle has recently completed trials in Arizona and described work earlier this year in the United Arab Emirates as the most challenging desert conditions in which the vehicle has been tested. A number of modifications have been made to DAGOR, Olson said, notably to enhance cooling systems to support operations in high temperatures.
