The U.S. Army began fielding the new second generation Improved Outer Tactical Vest (IOTV), with first kits delivered to soldiers scheduled to deploy to the Afghan theater. Shipments will soon follow to units already in theater. “The latest design Gen-II IOTV vest includes 17 improvements over the Gen-I vest. The new IOTV is designed with more versatile, modular approach, allowing units to configure their gear to better confront multiple threat levels in their unique environment” said Major Craig Fournier from PEO Soldier.

Improvements include a totally redesigned and removable yoke and collar, reversible and detachable side carriers and universal side pouch, and equipment anchor points on the front and rear which interface with items such as hydration systems and the Tactical Assault Panel or (TAP). In addition, the new design has better adjustability in the shoulders and hips, to better fit all sizes. The newly designed location for the side-plate is also adjustable to the wearer. Given the enhanced flexibility and modularity of the new kit, soldiers will be able to wear a more comfortable vest, and carry just the equipment they need for a mission. When required or possible, they could strip the IOTV down to its basic function, becoming a light weight load carrying vest, retaining effective protection, maneuverability and flexibility.

“A mounted soldier manning an MRAP turret has the option to utilize all accessories such as deltoid, front, and back protectors for maximum protection, while a dismounted soldier in the mountains can strip the IOTV down to the base vest, removing the side pouch, side plates, and accessory pieces, slimming the IOTV down to a trim 9.86 pounds, minus the plates” Maj. Fournier added, “this configuration gives the commander the flexibility to reduce the combat load while still maintaining increased fragmentation and 9mm protection.” Kits are currently produced in Operational Enduring Freedom Camouflage Pattern (Multicam) and the Universal Camo Pattern (UCP).

The U.S. Army Research Development and Engineering Command (REDCOM) have ordered 660 Enhanced Night Vision Goggles (ENVG) from three manufacturers for testing, toward massive fielding of new ENVGs in upcoming years. The awarded companies are ITT, L-3 Insight Technology and DRS Systems. The three contracts, each valued around US$250 million, cover the delivery of the 220 systems in the base year, (2010) and options for the delivery of production quantities in the years 2011-2013. The Army is expecting to field new and improved digital fused imaging goggles by 2014.

Sofar ITT has been producing the Army’s first generation AN/PSQ-20 ENVG under a sole source indefinite-delivery, indefinite-quantity (IDIQ) contract worth about $560 million. This contract expires by the end of 2010. ITT has already provided over 2,400 ENVG systems with another 6,500 to be delivered on the current contract.

The development of the ENVG began in the year 2000. First models were fielded in 2008 with special operations units. By early 2009 the 10^th Mountain Division was the first regular Army unit to receive few hundred items . The recent follow-on contracts address an ENVG follow-on program, with ITT has addressed with an updated version of the current ENVG system, called ‘Spiral Enhanced Night Vision Goggle’ (SENVG). This new device is designed to meet high volume production rates and the critical performance requirements of the ground-based soldier.

The SENVG incorporates the 18 mm image intensifier tube and a display beam combiner assembly (DBCA) utilizing an OLED-XL microdisplay produced by eMagin. The SENVG utilizes several qualified ENVG subassemblies and is powered by three AA batteries, which reduces the logistics burden and gives the customer an estimated $130 million savings over the product’s life cycle. Through various system enhancements the SENVG has a digital upgrade capability that will allow the goggle to export fused imagery for transmission via battlefield networks.

Since the fielding of the ENVG PEO Soldier has been delivering ENVGs and in parallel, developing a lighter, more rugged digital system (ENVG-D), that will also support image transfer and display of images from other sensors and sights, Digital Video Recorders (DVR) and remote computing devices. The current systems are significantly more expensive and heavier, compared to the systems they are intended to replace – PVS-7 and PVS-14. The new ENVG (D) is expected to overcome these weaknesses and meet the Army’s objective weight and cost requirements.

Elbit Systems is expanding its family of man portable unmanned ground systems with the introduction of two new models. During a recent exhibition the company displayed the new robots, in addition to a wide range of advanced land and C4I solutions. The new members of the VIPeR family of intelligent and portable robots include the Mini-VIPeR and Maxi-VIPeR, which join the VIPeR robot, already operational in the Israel Defense Forces under the Hebrew name “Pazit.”

All VIPeRs are designed for portability and high mobility; the robots are configurable for multiple types of missions by add-on sensors, modules and payloads, tailored to specific tasks. The Viper is controlled by a single operator, and is designed to negotiate obstacles typical of an urban environment, such as climbing stairs and rubbles, when performing surveillance, reconnaissance and support troops in urban warfare missions.

The VIPeR vehicle uses the “Galileo Wheel”, a patented wheel that can be transformed on the move into a triangular track, developed by Galileo Mobility Instruments ltd. This unique automotive system enables the robot to climb stairs, negotiate difficult terrain, move over barricades, dense vegetation and other obstacles.

The Mini-VIPeR and Maxi VIPeR robots use a more common track system. While the two new robots bear some resemblance to the Beagle, developed by Elbit Systems of America, a closer look at the two new robots reveal more similarities to the locally designed VIPeR. The larger version uses a wide, heavy duty track system, adapted from the VIPeR for outdoor operation over rugged terrain. The smaller robot uses a narrow track, more suitable for indoor operation.

Both have body mounted sensors, flat top and bottom surfaces, for the mounting of mission payloads.  The Mini-VIPeR is a light-weight, one-person portable system (weighing approximately 3.5 kg), equipped with advanced sensors that allow full operation in adverse terrain. Thrown into a dark tunnel or tossed through a window, into a room, the mini-Viper allows warfighters to survey structures before entering. The larger, yet compact Maxi-VIPeR robot is designed to carry sensors and tele-operated manipulator arms, for the handling of unexploded devices and other hazardous materials including radioactive materials.

Seeking innovative solutions to lighten the load carried by dismounted warfighters, the U.S. Army Natick Soldier Center awarded US$1.1 million for the testing and evaluation of Lockheed Martin HULC advanced robotic exoskeleton, designed to augment Soldiers’ strength and endurance, as well as reduce load carriage injuries. Dismounted Soldiers often carry heavy combat loads that increase stress on the body, leading to injuries and exhaustion.

HULC is designed to transfer the weight from heavy loads to the ground through the robotic legs of the lower-body exoskeleton, taking the weight off of the operator. An advanced onboard micro-computer ensures the exoskeleton moves in concert with the operator. HULC is an un-tethered, battery powered, hydraulic-actuated anthropomorphic exoskeleton capable of performing deep squats, crawls and upper-body lifting with minimal human exertion.

Under this contract the U.S. Army will test an upgraded HULC system, that includes optimized control software, extended battery life and human factors improvements for quicker and easier sizing to each user. 

The contract includes options for field trials to test the system’s utility in operational environments. According to David Audet, leader of the Soldier Mobility and Mission Enhancement Team at the Natick Soldier Research Development and Engineering Center in Massachusetts, the test will assess the contribution of Exoskeletons which have the potential to reduce stress on the body from heavy loads.

Researchers at Natick will evaluate how the HULC affects Soldiers’ performance through biomechanical testing, measuring the energy expended by a Soldier when using the HULC. Lab testing will also assess how quickly soldiers learn and adapt to the system, carrying different loads and moving at various speeds. The exoskeleton test will help “redefine what is possible for our Soldiers… HULC will meet Warfighters’ future mobility and sustainment needs” determined Rich Russell, director of Advanced Programs at Lockheed Martin Missiles and Fire Control. Lockheed Martin is also exploring exoskeleton designs beyond military uses, among them supporting industrial and medical applications.
