The IAV Stryker is a family of eight-wheeled all-wheel-drive armored combat vehicles produced by General Dynamics Land Systems, in use by the United States Army. Based on the Canadian LAV III light-armored vehicle, which in turn is based on the Swiss MOWAG Piranha III 8x8, the Stryker is the U.S. Army's first new armored vehicle since the M2/M3 Bradley Fighting Vehicle in the 1980s.
The Stryker was championed by General Eric Shinseki when he was U.S. Army Chief of Staff. The vehicle is employed in Stryker Brigade Combat Teams, light and mobile units based on the Brigade Combat Team Doctrine that relies on vehicles connected by military C4I networks.
Design
Pneumatic or hydraulic systems drive almost all of the vehicle's mechanical features; for example, a pneumatic system switches between 8X4 and 8X8 drive.
The vehicle comes in several variants with a common engine, transmission, hydraulics, wheels, tires, differentials and transfer case. Two exceptions are the M1130 Command Vehicle and M1133 Medical Evacuation Vehicle, which have an air conditioning unit mounted on the pack. The medical vehicle also has a higher-capacity generator. A recent upgrade program provided a field retrofit kit to add air conditioning units to all variants.
[edit] Power pack and mechanical features
For its power pack the Stryker uses a Caterpillar diesel engine common in U.S. Army medium-lift trucks, eliminating extensive retraining of maintenance crews and allowing the use of common parts.[2]
Designers strove to ease the maintainer's job, equipping most cables, hoses, and mechanical systems with quick-disconnecting mechanisms. The engine and transmission can be removed and reinstalled in less than one hour, allowing repairs to the turbocharger and many other components to be done outside the vehicle.
Because of obsolescence concerns, the Caterpillar 3126 engine was recently replaced by a Caterpillar C7 engine. The C7 shares a common engine block with the 3126.
[edit] Command, Control, and Targeting
Extensive computer support helps soldiers fight the enemy while reducing friendly fire incidents. Each vehicle can track friendly vehicles in the field as well as detected enemies.
A day-night thermal imaging camera allows the vehicle commander to see what the driver sees.
Soldiers can practice training with the vehicles from computer training modules inside the vehicle.
The driver and the gunner have periscopes that allow them to see outside the vehicle without exposing themselves to outside dangers. The gunner has almost a 360-degree field of vision; the driver, a little more than 90 degrees.
General Dynamics Land Systems is developing a new Power and Data Management Architecture to handle computer upgrades.[3]
