M1165A1 Special Operations HMMWV, United States of America
M1165A1 Special Operations high-mobility, multi-purpose wheeled vehicle (HMMWV or Humvee) is a variant of M1165 general-purpose HMMWV customised for the specific needs of special forces.
The vehicle is designed and developed by AM General, a vehicle manufacturer based in Indiana, US. An export variant of the M1165A1 was introduced at the Latin America Aerospace and Defence (LAAD) exhibition held in Rio de Janeiro, Brazil, in April.
The special operations Humvee variant is designed to be manoeuvrable in all terrain conditions, while providing increased protection for its occupants. It is suitable for missions such as patrol, command and control, utility, and special operations.
M1165A1 Special Operations HMMWV design and features
The M1165A1 Special Operations vehicle is based on a four-wheel drive chassis and is transportable by air, land, sea-based vehicles.
The gross and kerb weights of the vehicle are of 5,488kg and 3,279kg respectively. The vehicle can carry payloads weighing from 2,209kg to 2,245kg based on the mission requirements. It has a fuel carrying capacity of 95l.
The M1165A1 Special Operations HMMWV is manned by four crew members, including a driver.
The payload options include 2, 3 and 4 bay ammo can storage bins, equipment shelf with stowage box and hood-mounted Pioneer tool kit, and a spare tire carrier mounted on the A-frame.
An air-conditioning system is installed in the crew cabin to create comfortable operating conditions for the crew.
The vehicle is armed with a 12.7mm machine gun, installed on a weapons mount on top of the vehicle. The weapons mount can be accessed through a large circular roof hatch.
Up to three 7.62mm general-purpose machine gun mounts can be fitted to the side doors of the vehicle to provide defence against lightly armoured ground targets and personnel.
Additionally, the rear section can be equipped with up to four gun mounts with pintle.
Protection kits on the multi-purpose vehicle
The M1165A1 Special Operations vehicle features factory-installed armour packages along with ballistic and mine blast protection kits.
It can be optionally provided with additional field-installable armour and fragmentation protective kits to further increase protection from projectiles and grenade fragments.
Power for the M1165A1 Special Operations HMMWV comes from a single V8, 6.5l turbocharged diesel engine located in the forward portion of the vehicle. Developed by AM General's subsidiary General Engine Products (GEP), the engine generates an output power of 190hp at 3,400rpm and a torque of 515Nm at 1,700rpm.
A four-speed transmission system, also made by GEP, is connected to the engine to provide better driving performance.
The vehicle incorporates independent double A-frame suspension at both front and rear. Front suspension is provided by coil spring and telescopic shock absorbers, while variable rate springs, coil springs, and telescopic shock absorbers are fitted for rear suspension.
The M1165A1 HMMWV's powertrain also consists of hypoid gear differentials at the front and rear with a gear ratio of 3.08:1. A two-speed transfer case is installed to ensure increased mobility on off-road conditions.
The brake system consists of disc type service brakes and dual disc, independent parking brakes.
