Leonardo DRS has been selected by the US Army to demonstrate its on-board vehicle power (OBVP) technology on the Terminal High Altitude Area Defense (THAAD) missile battery’s command and control and launcher vehicles

System improvements will provide air defence operators with immediate access to electrical power directly from a vehicle's power train, and under the terms of the contract, Leonardo DRS’ land electronics business will integrate OBVP systems into THAAD medium tactical vehicles to be demonstrated to the US Missile Defense Agency and the army.

The technology is designed to meet the DoD's growing power needs, DRS said, and the OBVP systems are integrated within the vehicle's transmission to generate up to 55kW of usable electrical power while on the move or up to 120kW of usable electrical power while stationary. 

Leonardo DRS, partnered with Allison Transmission, will jointly provide existing OBVP systems based on the Allison 3200 SP transmission, and will develop an OBVP system for the Allison 4500 SP transmission. 

This integrated power system powers the mission equipment package payload without taking up extra space like auxiliary power units, tunnel/skid-mounted generators or tow-behind generators do.

The Leonardo DRS OBVP system has proven it can increase battlefield agility, reduce deployment logistics costs, and improve mission readiness with no impact on vehicle functionality, the company added. 

A 2016 US Army Tank Automotive Research, Development and Engineering Center (TARDEC) Vehicle to Grid (V2G) study reported a 23% fuel saving in comparison to tactical quiet generators when employing OBVP technology for grid power.
