A specialized vehicles with extreme capabilities

Specialized reconnaissance attack and transport system evolved from a proof-of-concept vehicle and is usually recognized as an SRATS. The SRATS uses popular Rock crawler and Sand rail Technologies popular in extreme off-road automobile racing. It is used to make an all-terrain vehicle that is designed for extreme terrain in all weather conditions.


In 2004, the Defense Advanced Research Projects Agency (DARPA) funded the development of two prototype vehicles as part of a proof-of-concept demonstration of a small vehicle that would bridge the gap between the soldier and the HMMWV. In 2007, the US-based BAE Systems and the SRATS developer specialty vehicle manufacturer announced their agreement to convert the militarized rock crawler into a mass-produced military vehicle. This was a direct response to the U.S. Army’s interest in acquiring new military vehicles to support their light brigades and special forces.


The SRATS combines commercial rock crawler and sand rail technologies. In addition to an automotive platform designed for mobility under extreme conditions, it is equipped for almost vertical climbing on rock or crossing gravel fields (maximum gradient of 80%). The vehicle also has high acceleration and speed so a quick chase or quick exit from a hot target area can be sustained with sustained firepower.

the Specialized reconnaissance attack and transport system went through field tests and demonstrations in November 2004. The tough demonstrations simulated reducing soldiers’ backpacks by 80 percent or more and providing logistical support to the infantry wherever a soldier could walk or climb. The SRATS vehicles demonstrated their ability to tackle extreme terrain, drive over rubble, and drive through roadless terrain. They have also been tasked with simulated high-speed convoy escorts, evacuating the injured, and tracking insurgents off-road.

Technical specifications

The SRATS weighs 4,700 pounds curb and is equipped with an upgraded HMMWV turbo diesel engine rated at 340 hp on JP8 fuel. A single Chinook CH-47 lift can carry two carriers. The carrier offers space for four passengers, another six sit on outboard platforms. It can be fitted with a 2,000 pound armor package that provides efficient protection against 7.62 rifle bullets and less caliber. The SRATS carrier can be configured with independent front and rear steering for maximum agility and maneuverability in extreme conditions.

The first SRATS was completed in 2006 as a “Proof-of-Principle” vehicle for the US Defense Advanced Research Projects Agency (DARPA) and aroused great interest among members of the special forces. The US military was ready to order over 100 of these in the first phase. Nonetheless, interest spread beyond the special forces, and the Army’s Rapid Equipping Force (REF) was interested in producing thousands of these vehicles. This potential motivated the SRATS developer to turn to the BAE Systems team to develop and produce a new armored version with improved capabilities.


Designed to bridge the gap between the current HMMWV (Humvee) military vehicle and the dismounted soldier, the SRATS armored carrier provides support and logistics for small infantry elements. It means escorting and mobilizing convoys on and off-road, performing clandestine reconnaissance missions, extracting high-quality assets in difficult locations, and performing quick off-road and on-road tracking, and being able to withstand gunfire.

SRATS is 175 ″ (4,445 m ‘) long and has a wheelbase of 132 ″ (3,352 m’), the vehicle curb weight is approximately 6,500 lbs (2,948 t.) For the unarmored version and 8,500 lbs (3,856 t.) For the armored version Vehicle equipped with handgun protection (7.62 mm) and run-flat tires.

In either configuration, the SRATS carrier can carry a payload of 4,000 lbs (1,814 t), including four passengers when fully equipped. The carrier is powered by an AM General 6.5 V8 turbo diesel engine with an output of 300 hp and a torque of 505 lb / ft. It uses standard fuel tanks to keep it operating at 375 miles (60 km) or to accommodate larger fuel tanks for greater range.

After years of testing and testing, SRATS finally comes out as an end product as ELSORV, which stands for Enhanced Logistics Off-Road Vehicle. It’s similar to a Humvee, but with a lot more agility and off-road capabilities. It is based on a SRATS design for SOCOM from the past five years.
