The power of the M1152A1 HMMWV is a GM 6.5-liter V8 turbocharged diesel engine (formerly known as Detroit Diesel Engine, also used in other Hummer series vehicles), matched with a GTP 4-speed automatic transmission, outputting a maximum horsepower of 193 horsepower at 3400 rpm, Full-time four-wheel drive, strong off-road capability. The cab is armored. In addition to the Hummer, the chassis can also be replaced with other vehicles, such as the Mack Sherpa light tactical vehicle, which also uses an armored cab; standard pickup truck chassis, such as the Ford F-250, are also available.
Mack Sherpa Chassis
Designed to replace the 105mm towed howitzer, the Hawkeye has a modular design and is more automated than the latter and can be quickly redeployed. Its M20 105mm 27 caliber light howitzer can fire standard NATO 105mm ammunition. The maximum range when launching ordinary bombs is 11.5 kilometers; the maximum range when launching rocket-extended range bombs is 15.1 kilometers. Using a semi-fixed cartridge, the amount of propellant can be adjusted. In addition to curved shooting, the gun can also shoot directly, with a range of 2000 meters. Before launching, put down the 2 jacks on the front of the vehicle and the auxiliary hoe on the rear to fix the vehicle body, and the artillery can rotate 360°. Ammunition includes high-explosive, flare, rocket-extended range (RAP), high-explosive fragmentation (HEPF) and smoke.
The vehicle is designed to use barrels of various lengths, and customers can customize the length of the barrels according to their range needs. The gun has a fast rate of fire, basically equivalent to a 105mm towed howitzer, with a burst rate of 10-12 rounds per minute, a continuous rate of fire of 3 rounds per minute, and remote control shooting.
Due to the short range, the system needs to operate near the front line. The artillery is equipped with a hydraulic system and adopts soft recoil technology. Compared with traditional artillery, the recoil force is reduced by 50%, making the Humvee chassis strong enough to withstand the impact of the artillery launch.
In terms of fire control, the gun has an automatic digital fire control system, including LN-270 inertial navigation system (INS), MVR-700C muzzle velocity radar system, DFS-02 direct camera system, S67-1575-76 GPS antenna and DK10 gunner display ( GDU). Also equipped with an optical fire control unit with M187A1 telescope mount and M137A2 panoramic telescope.
In 2014, India publicly demonstrated its similar Garuda 105 light vehicle howitzer, which also uses the Hummer chassis, soft rear seat technology and a digital fire control system.
