On-Board Vehicle Power (OBVP) provide Mobile Forces Power- Anywhere, Anytime

Current military threats have created a tremendous requirement for mobility for successful execution of missions. Therefore military is now in a rapid transformation to become a lighter, more agile, mobile, networked and more lethal force. To become more lethal and better networked involves new weapons systems and more sophisticated electronic systems, both of which demand more DC and AC power. On-board devices such as sensors or communication and weapon systems require a continuous power supply.  Militaries have traditionally solved this by hauling larger, heavier diesel generators around on a trailer.


OBVP refers to providing an alternative source of AC power on the battlefield that is generated from the vehicle itself which can solve many technical and logistical problems.   For example, by providing the HMMWV with a 10 -KW OBVP system supplying continuous AC power, the need to trailer a diesel generator is reduced significantly. In addition, now the HMMWV can negotiate terrain that it could not previously engage while towing a generator, thus leading back to the more agile concept.


The OBVP system is compatible with the Department of Defense’s objective of evolving from conducting operations from forward positioned bases, common in Iraq and Afghanistan, to an expeditionary mindset where units rapidly deploy to austere environments and are immediately prepared to begin operations.



The OBVP systems also have potential uses off the battlefield. State and local emergency response agencies could use such systems during natural disasters to power emergency shelters, for example. When daisy chained, such systems could power hospitals, senior citizen homes, water purification plants or other vital infrastructure.



TITAN On-Board Vehicle Power (OBVP) vehicles can support a variety of military missions: Mobile Command Posts (MCP), Tactical Operation Centers (TOC), Combat Operations Center (COC), Company Tactical Command Post (TAC), or may be used to power a variety of emergency facilities such as field hospitals, triage units, fueling stations, or any other component requiring clean, reliable power.


The TITAN OBVP system has been designed, tested, and delivered to address the military’s increasing need for more electrical power to support missions. OBVP also reduces the logistical complexity by significantly reducing or eliminating the need for towed or tunnel generator requirements.


TITAN  equipped vehicles greatly improve the operational adaptability of the advancing forces by providing mobile, expeditionary power when speed, range, agility, and flexibility are critical to mission success. Whether it’s providing power to a tactical security checkpoint in Afghanistan or emergency power to critical facilities such as medical care or fuel and food distribution centers in time of Humanitarian need, Leonardo DRS’ TITAN OBVP solutions provides Power- Anywhere, Anytime!


Allison broadens onboard electrical power development for army

Allison and Leonardo DRS are exploring OBVP uses throughout the full range of wheeled and tracked vehicles.

Allison Transmission, in partnership with Leonardo DRS is developing On-Board Vehicle Power (OBVP) systems for  the 44-ton Oshkosh Heavy Expanded Mobility Tactical Truck (HEMTT) equipped with Terminal High Altitude Area Defense (THAAD) anti-ballistic missile launchers.


A generator will be fully integrated within the housing of an Allison 4500 Specialty Series™ transmission and installed into the HEMTT’s driveline in its original configuration, without affecting vehicle functionality. In fact, the OBVP will improve agility and reduce logistics costs because the vehicle will no longer have to be equipped with a separate generator. In addition, the OBVP is intended to improve mean time between mission failures.


The electrical loads on vehicles have increased dramatically. It’s getting more and more difficult to produce that level of power with an engine-driven generator/alternator. Allison is proud to be partnered with Leonardo DRS in the development of OBVP technology that will result in innovative and adaptive propulsion solutions that provide capabilities not available today,” said Dana Pittard, Major General (Ret.) and vice president for defense programs at Allison.
