X-band SATCOM On-the-Move Phased Array Antenna
August 6, 2012
BOULDER, Colo. – Ball Aerospace & Technologies Corp. has successfully demonstrated its Mobile Multifunction Low-Cost Array (MMLCA) system, a prototype X-band SATCOM On-the-Move (SOTM) phased array antenna, at the U.S. Army’s Aberdeen Proving Ground facility, Aberdeen, MD. The MMLCA system was developed for the Office of Naval Research (ONR) to demonstrate high data rate communications with military and commercial satellite systems. The system was developed under ONR’s FORCEnet Future Naval Capabilities program.
MMLCA is a self-contained low profile antenna system with no rotating parts for use by a variety of military combat vehicles and platforms. The system enables current and future military platforms to reduce the number of necessary antennas, provide better antenna coverage, and lower the overall silhouette of vehicles. Refinements identified during testing will be incorporated prior to fielding the system in an operational theater.
“MMLCA is significantly more rugged than competing conventional designs making it more impervious to weather and battlefield operations,” said Jim Oschmann, Ball Aerospace Vice President and General Manager for Tactical Solutions. “Additionally, it incorporates the advantages found in advanced phased array antennas including a lower profile design for hemispherical coverage, high-reliability, and lower total ownership cost.”

Link: TRADOC Assault Weapon System
Thanks to Joe Trevithick for making the site aware of this prototype.
FORT BENNING, Ga. (TRADOC News Service, Sept. 27, 2004) – The Army has developed a prototype of a vehicle that may change the future battlefield.
The Assault Weapon System, an experimental turret-mounted, multifunctional weapon system attached to a humvee, may put the firepower of an entire heavy-weapons platoon into one vehicle.
The system is the brainchild of Training and Doctrine Command, Raytheon and TRADOC System Manager-Close Combat Weapon Systems, and features an MK-19 grenade launcher, .50-caliber machine gun and two TOW missile-firing platforms.
All three of the weapon systems are connected to a central Improved Target Acquisition System that gives the gunner the option of firing each weapon with the flick of a switch and automatically gauges the range of the target by using an eye-safe laser range finder.
When the gunner flips a switch on the control panel and charges the weapon of choice, the display will change for the particular weapon and will show the sights for that weapon.
In older systems, the gunner would have to “walk in” the grenades when firing the MK-19, which means it would take several shots to hit the target. However, the ballistics for each weapon are already integrated into the ITAS, which gives the gunner better accuracy.
“This is probably the most flexible fire-support system to the day,” said Sgt. 1st Class Charles McCartney, Company A, 511th Infantry Regiment, Fort Bragg, N.C., who was showing the vehicle during the infantry conference Sept. 20-23. “The best part about it is its flexibility, the fact you can select the weapon you want to use.”
The system also features a networked, persistent, all-weather, extended range surveillance and target-acquisition capabilities for increased survivability and situational awareness.
The key to the improved communication is a system called Force XXI Command Battalion Brigade and Below, which provides a connection among all the elements on the battlefield. FBCB2 combines Global Positioning System technology with a long-range laser targeting system that keeps everyone on the battlefield connected using real-time audio video and text messages.
In essence, the unit’s operations center can watch the battle through the gunner’s sights and, if air support is needed, the position of the target will already be narrowed down to within 10 meters.
McCartney said it currently takes several vehicles and nearly a whole platoon to match the AWS’s versatility, and if the system is approved, it can greatly increase the Army’s fighting capabilities.
“We can have one vehicle doing the job of three, or we can have three vehicles doing three times as much,” he said.
The vehicle on display was a watered-down version of the tactical vehicle that is still in the construction phase.
Plans for the tactical version include a smaller, collapsible turret, removable composite armor plating, undercarriage protection from mines, a smaller targeting screen, and the gunner’s seat may be moved to the rear of the vehicle to allow for another team member and lower the distractions for both the gunner and the commander, said Wayne Spate, AWS program manager.

HMMWV With Chimney For Safety Draws Military's Interest
Special thanks goes to Patrick Keenan and http://www.warwheels.net/ for the notification of the story.
23 July 2011
An innovative chimney to vent blasts from buried bombs could make the Humvee safer and bring the most popular military vehicle since the Jeep back from the sidelines in Afghanistan.
The Humvee fell out of favor in Iraq and Afghanistan as homemade bombs, the biggest killer of American troops, ripped through its light armor and turned it into a death trap.
But recent blast tests show that Humvees built with the new chimney could provide as much protection as some of the heavier, and more costly, mine-resistant vehicles that have replaced them in many uses.
And if the final tests go well, the invention could save billions in new vehicle costs and restore much of the maneuverability that the Army and the Marines have lacked in the rugged terrain in Afghanistan, military officials say. Engineers say the chimney, which rises through the passenger cabin, releases some of the explosive gases — traveling at twice the speed of a fighter jet — that have mangled and flipped many of the vehicles.
Pentagon officials have said little about the 11 blast tests so far, in which the prototype vehicles are engulfed by a cloud of smoke, dust and fire, but the passenger cabin remains intact.
Dr. Leo Christodoulou, who has overseen the tests for the Defense Advanced Research Projects Agency, said in a written statement that the changes represented a “significant improvement” over the classic Humvees.
He said the new design also provided safety levels comparable to the smallest mine-resistant vehicles, which can weigh twice as much as the Humvees, and might be useful in protecting other military vehicles.
John M. McHugh, the Army secretary, recently told a Senate committee that the new approach held “a great deal of promise, and it’s exciting.” He said commanders had been reluctant to send Humvees off bases in Afghanistan “because of the problems with survivability.”
The chimney was designed by a small Maryland firm, Hardwire L.L.C., which is working with AM General, an Indiana company that has built 270,000 Humvees since the mid-1980s. Hardwire is run by a colorful group of aeronautical engineers who say they took a fresh approach to evaluating how to make the vehicles safer.
George Tunis, the company’s chief executive, likened the chimney to an exhaust vent on a rocket.
He said that rather than just piling on more armor to absorb the blasts, as has been typical in the past, the idea was to disperse as much of the explosive energy as possible.
Tests show that the explosive gas from a roadside bomb can accelerate to speeds as high as Mach 4 in less than a millisecond, Mr. Tunis said, or far less time than it takes to blink an eye.
Mr. Tunis said he was inspired to work on the vehicle’s safety after a chance meeting with Octavio Sanchez, a Marine staff sergeant who lost a hand and was badly burned when his Humvee blew up in Iraq in 2005.
Sergeant Sanchez said Friday that he told Mr. Tunis that small safety improvements might have saved his hand, “and I think that turned a light bulb on for him.”
Mr. Tunis said the chimney, which is hidden next to a gunner’s turret atop the Humvee, is the biggest change. But like the mine-resistant vehicles, the Humvee prototypes have V-shaped steel bottoms to deflect parts of the blasts.
Mr. Tunis said his engineers were inspired by sports gear in making other changes.
He said that Dyneema, a thin fiber that links surfboard riders to kite sails, is so strong that it is used in bulletproof vests, and that his team sandwiched plates of it between metal panels throughout the vehicles. It also adapted a rock-climbing device to drop the gunner into the vehicle when a blast occurs.
The Pentagon will conduct five more blast tests, and the Army could request bids this fall for a new version of the Humvee.
Several companies, including Oshkosh, BAE Systems and Textron, are expected to bid. Charles Hall, AM General’s chief executive, said his company had also been working with Plasan, an Israeli armor manufacturer, on another prototype.
But he said in an interview that the blast tests “demonstrate very clearly” that the chimney could offer protection well beyond what the Army was expected to seek.

TPI Composites and Armor Holdings, Inc. have unveiled a new light-weight, all-composite HMMWV. The new vehicle, which is part of the U.S. Army's All Composite Military Vehicle program, will be the first of its kind. The prototype vehicle was designed to demonstrate weight savings and durability in a tactical truck for the U.S. Army that can provide soldiers with maximum protection and performance.
The vehicle is the result of an 18-month research and development program with the U.S. Army TARDEC and AM General. The vehicle will serve as a demonstration of how TPI can apply its composites technology to other military vehicles or vehicle components produced by Armor Holdings. The All Composite Military Vehicle Program was a congressional initiative supported by Congressman Hobson. TPI's all-composite HMMWV saves approximately 900 pounds when compared to a current steel and aluminum HMMWV that is required to carry the same heavy armor. This weigh savings allows for the carriage of additional armor and other life-saving or important equipment.

Additional blast-protection is expected to become part of the recapitalization program for an estimated 60,000 U.S. Military HMMWVs, expected to be identified for repairs and underbody blast improvements. BAE is proposing the Integrated SMART V system, which stands for ‘Survivable, Modular and Affordable while utilizing a high Re-use strategy and proven innovative Technology.’
The ISV solution features a lightweight monocoque V-shaped hull with front and rear frame clips that attach to the hull to provide the most rigid side- and mine-blast protection available in one affordable package. According to BAE Systems, the ISV™ has significantly improved underbody protection with a highly survivable and adoptable modular design that has three distinct sections creating greater flexibility to tailor each vehicle. The ability to re-use the power train components and the use of low cost materials (not exotic) make this an affordable solution reducing the logistics footprint.
Oshkosh Defense is offering to upgrade the Marine Corps HMMWVs, enhancing its off-road mobility, maneuverability, and speed, while retaining, and even improving its ballistic protection and introducing V-shaped under armor for additional blast protection.

Oshkosh Defense is offering to upgrade the Marine Corps HMMWVs, enhancing its off-road mobility, maneuverability, and speed, while retaining, and even improving its ballistic protection and introducing V-shaped under armor for additional blast protection. The key for this miracle is the TAK-4 independent suspension system, customizing the tactical utility HMMWV into a customized off-road vehicle. Oshkosh is presenting the customized HMMWV at the Modern Marine expo in Quantico, VA.
The new suspension offers the vehicle a 70 percent off-road profile capability. The new suspension restores a 2,500-pound vehicle payload capacity in addition to the armor and occupants. Introducing 14 inches of independent wheel travel, the HMMWV can overcome obstacles and navigate rugged, mountainous environments. The vehicle’s performance is also improved in 40 percent increase in the maximum speed and a 46 percent improvement in braking. With ground clearance increases to 17 inches, and additional payload capacity, an under-vehicle V-shaped panel can be added, to further improve survivability from mine blasts and IEDs. The higher ground clearance further improves mobility and occupant visibility.

Link To Original Story: HMMWV Scorpion Mortar Carrier
Picatinny successfully designs mortar system for HMMWV
PICATINNY ARSENAL, N.J. -- An innovative team of armaments engineers here has successfully designed and tested a mortar that fires from a heavy military HMMWV , a technical breakthrough never before achieved.
Nicknamed Scorpion, the mortar could provide U. S. military personnel serving in hostile areas added protection, according to Anthony Franchino who headed the five person team.
Franchino led the effort to quickly find a way to equip the light, highly mobile, diesel-powered, four-wheel-drive vehicles with heavier firepower.
The HMMWV, which is designed for use on all types of roads, operates in all weather conditions and is extremely effective in the most difficult terrains.
It is used extensively by U.S. troops in Iraq and Afghanistan for a number of purposes including convoy protection, emergency response and mobile sentry.
Franchino said that the HMMWV’s light weight and compact size have limited it to medium caliber guns, soft-launch missles and small arms weapons until now.
“The vehicle’s mass acts as a significant constraint,” he said. “We believed that mounting anything larger than a medium-caliber direct-fire gun would exceed the structural limits of the HMMVW.”
The effort began when Col. Peter S. Janker, commander of Picatinny’s Armament Engineering Technology Center and Franchino’s boss, challenged the team to find a way to equip the HMMVW with a heftier weapon system than the one’s currently used.
“Col. Janker asked us to look for a fast, creative solution, not to develop a new armament capability,” Franchino said. “That’s exactly what we did.”
Utilizing a foreign-made 82mm auto-fire weapon that Franchino discovered while working on another program, the team began the project.
“We began tinkering with the mortar and a HMMVW that we obtained, often working on our own time during lunch, after work and sometimes on weekends,” he said.
During it’s initial test, the Scorpion successfully fired a single shot followed by several four-round automatic bursts at a remote location on the installation. Additional test firings were equally successful.
The Scorpion is both a direct and indirect fire weapon. It has a maximum range of 1000 meters for direct fire and more than 4,000 meters for indirect fire.
“It could allow military personnel riding in HMMVWs to destroy improvised explosive devices from greater distances than they now can, “ Franchino said.
