U.S. Military Manufacturing a Hybrid and Silent Motorcycle

According to science news article.

Significant to many a successful military assault is the element of surprise. If an attacking force can arrive undetected through terrain thought to be impassible the battle is half won. The American Defense Advanced Research Projects Agency, the arm of the Pentagon most responsible for shiny, futuristic technology, recently gave a $100,000 grant to Logos Technologies, Fairfax, Va.-based defense Tech Company, to develop, a hybrid silent -engine motorcycle for the armed.

What kind of activities or perform do the military with a motorcycle that runs nearly silently?

According to Wade Pulliam, the program manager at Logos Technologies” Popular Science that while there’s “no CONOPS concept of operations set in stone,” it would be ideal for missions deep into hostile territory. Helicopters and V-22 Ospreys could deliver troops and bikes to where they’d start the mission, and then troops would ride the bikes farther into difficult terrain. The bikes would use gasoline, JP 8 (a military jet fuel), diesel, and other fuels that could recharge the batteries as they propel the bike in the absence of electric power. The motorbike could also be used to charge electronic devices carried by the hordes.

In the words with Pulliam “DARPA wants, military users to be able to scavenge fuel while on missions,” so compatibility with a range of fuels is important. The bikes are also two-wheel drive, which gives them even greater ability to maneuver difficult terrain, such as narrow mountain paths and over collapsed trees.

The silent hybrid off-road motorcycle has a strange paternity. The body comes from BRD’s Redshift MX, an off-road all-electric motorbike. Its engine is based on a hybrid electric/fuel drone engine that Logos Technologies is currently developing. The point of the hybrid motorcycle is not fuel efficiency, though there could be some gains there. Instead, the military motorcycle would run electric only for up to an hour straight, which is one hour of nearly silent use. This is less than the two hours of running time that the civilian RedShift MX gets per charge, but the DARPA-funded bike project isn’t a direct modification of the RedShift; it’s a new hybrid bike that borrows some features.

DARPA’s noise goal is 55 decibels while running electric only, which is slightly louder than the ambient sounds of a quiet office and quieter than a normal conversation. That should be good enough to escape notice from all but the perkiest of ears. When running normally, the motorcycle will be 75 decibels slightly louder than a normal conversation but quieter than a debris dumping.

Hero Moto Corp of India makes one type of motorcycle already so it is not the first hybrid-electric motorcycle. But Pulliam raising points that this is the first developed that’s “multifuel and with two wheel drive.” Pulliam also expects that his team will start development of a prototype in the coming three months.

The capability of a military mounted on 2 wheels to launch a surprise attack was best demonstrated during World War II’s Fall of Singapore. Alan C. Headrick, in his excellently titled study “Bicycle Blitzkrieg: The Malayan Campaign and the Fall of Singapore,” describes how the Japanese attackers managed to catch the British defenders from an approach they through was impassible.

Prejudiced by the penetrating heat and impassable jungle, Japanese planners decided from the beginning to use bicycles rather than horses as a means of troop and light material transportation. This decision allowed the foot soldiers to travel farther, faster, and with less fatigue. Due to the vast number of rivers on the Malay peninsula, and the British propensity to destroy the more than 250 bridges they crossed during their retreat, bicycles allowed the infantry (to continue) their advance, wading across the rivers carrying their bicycles on their shoulders, or crossing on log bridges held up on the shoulders of engineers standing in the tributary.

However another Fall of Singapore-scale motorbike assault is unlikely, a silent and capable bike increases the reach of a military to otherwise inaccessible nooks and crannies of the world.
