Excalibur Army (Hall A, Stand A357) of the Czech Republic is expanding its range of wheeled armoured fighting vehicles (AFVs) with the introduction of the latest Tatra T815 Patriot (4x4) Medium Armoured Tactical Multi-Mission Vehicle (MATMMV), which is being shown at Indo Defence.
This has been designed as a private venture using company funding to provide the end user with a 4x4 vehicle with a high level of protection and mobility that can be used for a wide range of battlefield missions with little modification.
Based on a Tatra cross-country chassis, it features adjustable ground clearance, and a central background tube with independent swinging air-suspended half axles that have been designed to improve cross-country mobility as well as improving ride for the crew.
The gross vehicle weight is currently being quoted as 12 tonnes, but it has a stretch potential to 15 tonnes because each axle is currently rated at 7.5 tonnes.
The MATMMV is powered by a Cummins ISB six-cyclinder diesel developing 210kW (with a Tatra air-cooled diesel developing 230kW as an alternative), which is coupled to an Allison 3200SP automatic transmission with six forward and one reverse gear and a Tatra two-speed transfer case. This gives a maximum road speed of 130km/h and a range of up to 500km. Standard equipment includes a central tyre inflation system that allows the driver to adjust the tyre pressure to suit the terrain being crossed.
The Patriot MATMMV features an all-welded steel hull of a patented design that the company calls the ‘Kitted Hull Concept’ and which is claimed to provide ballistic protection up to NATO STANAG 4569 level 3 and mine protection to the STANAG 4569 Level 2a/2b standard. The baseline vehicle has a crew of two consisting of commander and driver, plus four dismounts.
The first version is referred to as the short wheel base (SWB) model and has a wheel base of 3.50m, but a 3.65m long wheel base (LWB) version is expected to be completed early in 2019, providing more volume and payload.
