The US Army has been using jet fuel (JP8) for its tanks since 1995
The US Army has been using jet fuel, specifically JP-8 (Jet Propellant 8), to power its tanks since 1995. JP-8 is widely used by the US military and was introduced at NATO bases in 1978. It is derived from kerosene and contains additives for military use, such as corrosion inhibitors, lubricants, and antistatic agents. It is also used as a coolant in engines and other aircraft components.
The use of JP-8 in the US Army is part of the wider context of the 1986 NATO Single-Fuel Concept agreement, which aims to simplify logistics by using a single fuel type for land vehicles and aircraft. JP-8 is specified by MIL-DTL-83133 and British Defence Standard 91-87, and it is similar to commercial aviation's Jet A-1 fuel but with additional additives to enhance performance and safety.
While JP-8 has been a standard fuel for the US Army's tanks, it is important to note that tanks can operate on various fuels. For example, the M1 tank engine can use ordinary gasoline, diesel fuel, or jet fuel. The choice of fuel depends on factors such as fuel availability, engine specifications, and operational requirements.
The US Army's decision to adopt JP-8 as the primary fuel for its tanks was driven by several factors. JP-8 is known for its low flammability and reduced hazards, making it safer for both soldiers and equipment. It also offers logistical advantages by simplifying fuel supply chains and reducing costs. Additionally, JP-8's performance characteristics, such as its ability to function in a wide range of environmental conditions, contribute to its selection as the preferred fuel for military operations.
However, the use of JP-8 in diesel engines has presented some challenges. It has been associated with increased wear and tear on engine components, particularly during cold starts and idling due to low compression temperatures. Additionally, JP-8's lower density and viscosity compared to diesel fuel can result in slightly reduced torque and fuel economy. Despite these minor issues, the US Army continues to rely on JP-8 for its tanks, balancing the benefits of standardized fuel with the need for ongoing engine maintenance and performance optimization.
