September 22, 2005: Billions of dollars are being thrown at the IED (roadside bomb) problem in Iraq. This means that a lot of ideas that would, in normal times, never get money, now do. Some are strange, and useless, and diligent muckrakers will eventually get to them. But some are pretty interesting, and potentially useful. One of them is the ULTRA AP, a heavily modified Ford F-350 pickup. The 350 (and its cousin, the 250) are favorites with police and armed forces in many nations. The Afghan army recently bought 5,000 modified (for harsh cross country terrain) F-350s for their army. The ULTRA AP (for Armored Patrol) was designed to reflect some of the ideas coming out of Iraq, on how to design a more effective âarmored truckâ for combat patrols in an area where you are likely to encounter mines, roadside bombs and ambushes. The F-350 was selected because it is a mature, proven design that provides a good starting point. The Office of Naval Research (which does stuff for the marines), turned the Georgia Tech Research Institute (which does a lot of defense work, and is considered the âMIT of the Southâ) loose on the project. | They also had a little help from NASCAR |
The first mod was the use the light-weight armor that was being used by military trucks in Iraq. This included bullet and blast proof glass. The next mod was more interesting, and based on suggestions from the troops. The seating was changed from four people sitting two by two, to a diamond, one by two by one, arrangement. This meant replacing the current body of the 350 with a new one that made the ULTRA AP look more like an armored car. But this did two important things. It got the passengers farther away from the wheels, which are the things that go over mines and take much of the blast. Second, it put the four passengers in positions troops consider more useful. The driver is in front, taking care of driving. The two passengers behind the driver face the left and right. The fourth passenger faces the rear. This way, the passengers are always giving the vehicle a view of potential threats coming from any direction. The passenger compartment is actually a âblast bucket,â with armor beneath the passengers that deflects much of the blast away. The designers also took advantage of the computer networks that are now standard in motor vehicles, and provided the driver with more control over maneuvering the vehicle on roads, and cross country.
The Office of Naval Research will test the ULTRA AP to see if the design concepts are worth incorporating into future military vehicles. Some more may be built so that they can be tested with mines and roadside bombs as well. |
