Corps to upgrade aging LAVs while searching for a replacement

By: Lance M. Bacon, September 24, 2016

The Marine Corps' light armored vehicles qualify for antique license plates in most states, but the service is planning to upgrade half the fleet and keep them in service until 2035 while it searches for a next-generation replacement. 

It’s not a best-case scenario, officials said, but it is the best option as the Corps tries to find money to replace old vehicles and implement new technologies. 

The Corps is in a zero-sum game, according to Lt. Gen. Robert Walsh, commanding general of Marine Corps Combat Development Command. Because there is no new money coming in, leaders must get rid of one or more things to bring in something new. As the Corps develops new technologies to meet emerging threats, trade-offs will be necessary. 

“You're going to have to take away some of the current readiness, and take a little bit of risk to take some of that money to invest in future modernization and readiness,” Walsh told Marine Corps Times. 

Budget and time constraints mean the Corps will use part of its money to upgrade only half of its 800-vehicle fleet, doubling their service lives, and use the rest to develop a replacement. The hope is that upgrades will enable the aging fleet to meet all missions until that replacement comes online. Units that deploy will do so with upgraded vehicles, said Kurt Koch, the combat vehicle capabilities integration officer for Fires and Maneuvers Integration Division. 

The Corps is taking a similar approach with the amphibious assault vehicle. A portion of the AAV fleet is receiving major upgrades as two companies, BAE Systems and SAIC, compete to build the new Amphibious Combat Vehicle. 

The total number of AAVs and LAVs could change as service officials determine the size and shape of its future force, Walsh said. In the meantime, it must make the most of an aging LAV fleet that was supposed to retire in 2003. Repeated engine rebuilds and heavier armor have weakened the vehicle, but the Corps is not ready to put the pig out to pasture. 

Current A2s carry many upgrades such as better blast protection, an electronic LAV-25 turret, and an improved thermal sight system. The anti-tank variant will see the obsolete Emerson 901, an Army turret based on 1960s technology, replaced with the M220E3 TOW beginning next year. In coming years, a mobility and obsolescence kit will tackle the top three readiness drivers by providing a modern powertrain (new engine and transmission), drivetrain improvements to the transfer case and drive shafts, and an upgraded steering system. The kit will also replace the driver’s analog information panel with a digital board, and put a larger slip ring in the LAV-25 so it can pump more power to the turret. 

“The Marine Corps is taking adequate actions to keep the vehicle relevant and operational to 2035,” said Steve Myers, deputy program manager for Light Armored Vehicles. Recognizing he has no maneuver room in the budget, Myers said he would like to keep the cost at $525,000 per kit, but those decisions are still in the making. Specific vehicles to be upgraded has not been determined, but he expects that to be known within the year. 

The upgraded kits are in the engineering, manufacturing, development phase; production is expected in fiscal 2019. The first vehicles will roll out in 2021, and all planned upgrades will wrap up five years later. 

That’s good news for Maj. Christopher Ferguson, operations officer for 2 nd Light Armored Reconnaissance Battalion at Camp Lejeune, North Carolina. He has three LAV deployments under his belt, to include a combat tour in Iraq. While upgrades and service life extension “have absolutely helped,” there is no doubt his vehicles are getting older. He said upgrades to suspension must be a priority. With a salute to the Marines who keep them running, he said parts obsolescence is an increasing challenge. The need for maintainers to fabricate parts and tools is “a little above negligible,” he said. While there has been an increase in man hours, it has not been significant. 

Not yet. 

“We are annunciating a gap in capability,” Koch affirmed. “We are laying down where we are falling short and we will compete for resourcing for the next-generation armored reconnaissance acquisition effort. We are anticipating a program in the late 20s.” 

Koch doesn’t expect any leap-ahead vehicle technology in the coming decades. That means the next-generation vehicle may closely resemble the upgraded LAV. What he is looking for is “a good base vehicle with plenty of growth margin” that has sufficient maneuverability, protection, and lethality. The key is the ability to easily and incrementally add new technologies as they mature. 

“This is not merely a reconnaissance and surveillance asset. It possesses the organic ability to grab the enemy by the collar and punch them in the face in order to get information,” Koch said. “We’re going to have to improve the organic lethality, both direct and indirect fires. We think we will be doing that in a broader and more complex battle space. The ranges and capabilities and capacities will be stretched beyond what we currently treat as normal.” 

Koch spoke of expanded network capability, the need for more effective sensors, and the ability to counter unmanned air and ground systems. Topping Walsh’s list was more signals intelligence and longer range fires. Both spoke of organic electronic warfare, and a greater use of unmanned assets to extend the battlespace. 

“What we see in the future is these scouts launching an unmanned system off their vehicle,” the three-star said. “That UAS is out there scouting, and could be scouting autonomously to search a designated area for specific silhouettes. It may be programmed to report such findings, or pre-approved to attack.” 

Ferguson understands the need to evolve, but voiced concern that changes not become too complex, but instead “maintain a brilliance in the basics.” 

“Something that is survivable and reliable is good enough,” he said. “We’ve benefitted from not requiring contractor support to run and operate this system. I generally agree with a modular platform, as long as it doesn’t require extensive contractor support and crazy training.” 

While his Marines have used the Raven UAS with great results, he said such benefits should never come at the expense of having eyes on the objective.

The major said a new LAV should maintain the ability to maneuver water obstacles, commonly called its swim capability. If possible, he would like to see lighter and scalable armor. Increased weight has not been a problem, but is a consideration in amphibious delivery and combat maneuver. Simply put, “mobility is central to our platform.” 

Koch concurred. The LAV cannot remain mobile and effective if the Corps keeps piling on passive armor, he said. Developers are looking to lighten the load with scalable as well as active protection — soft- and hard-kill technologies to include directed energy.

Story by Ashley Calingo 

Marine Corps Systems Command  



Marine Corps Systems Command is modernizing the tank commander’s weapon station on the M1A1 tank by developing a suite of systems that give tank commanders and their gunners a hunter-killer edge over their enemies. 

The new Abrams Integrated Display and Targeting System, Tank Commander Single Handle and slew-to-cue capability make up the modernized trifecta that cuts time to enemy engagement by half while increasing accuracy, range and lethality on the battlefield.


Responding to feedback from Marines, the Abrams Integrated Display and Targeting System, or AIDATS, upgrades the thermal and day sights on the stabilized commander’s weapon station through a state-of-the-art, high-definition camera and permanently mounted color display. 

“The most significant benefit—the main reason why AIDATS was started—is the color display,” said Michael Kreiner, AIDATS project officer in MCSC’s Armor and Fire Support Systems. “Users didn’t like the black and white camera that was in the tank before, because they have a hard time distinguishing between different color trucks.” 

In battle, situational awareness is key for tank commanders. Kreiner and his team are leveraging technology currently available in the marketplace to provide a thermal sight that can be used around the clock and provide a color day camera with a color display.

“The thermal sight can be used for 24 hours,” said James Shaffer, systems engineer in AFSS. “It has low light capabilities, can see through obscurants, and works in the diverse environments under adverse weather conditions.”

The display for both upgraded thermal and day sights will be hard mounted in front of the tank commander, allowing him to minimize extra movement and focus on the action. Better optics enable commanders to increase identification and detection range while in the tank, which will improve situational awareness.

With AIDATS, tank commanders will have double the identification range with thermal sight and triple the identification range for the day sight, said Gunnery Sgt. Dennis Downes, M1A1 project officer in AFSS.

“AIDATS also has an azimuth indicator that will allow the tank commander to identify where his weapon is in relation to the vehicle at that moment,” said Downes. “On the legacy system, the tank commander had no situational awareness of where the weapon system is in relationship to the turret.”


In addition to providing tankers better line of sight, the AFSS team is improving tank handling for the commander.

“There’s currently one set of controls for the stabilized commander’s weapon station and another set of controls to operate the turret,” Downes said. “Combining the two handles into one gives the commander a better workspace.”

Reducing the number of handles the tank commander controls increases the overall efficiency of the system, leading to faster engagement times, he said.


The third upgrade to the tank commander’s weapon station has yet to be officially named, but the AFSS team currently refers to it as “slew-to-cue.” This new capability enables the tank commander to move the turret, typically controlled by the gunner, over to a target with the push of a button.

“With slew-to-cue, the tank commander can push a button on his single handle and, as long as the gunner has his handles engaged, the turret will automatically slew to what the commander is looking at on the 0.50-cal machine gun sight,” said Kreiner.

This additional capability allows the commander to assist the gunner when the tank is moving, making it easier to manipulate the turret toward a target, said Shaffer. Preliminary tests show the three systems used together reduce target engagement time from six seconds to three seconds. The team hopes to field all three systems simultaneously in the first quarter of 2018. Currently, the team is conducting qualification testing on five demonstration AIDATS systems at the Aberdeen Proving Ground in Maryland.

“We’re pushing the envelope where you can actually see the target, identify it and engage it at a farther range,” Kreiner said. “All three things combined will significantly reduce the engagement time, and essentially give tank commanders and their gunners a hunter-killer system.”

AFSS equips Marines with fire support systems, High Mobility Artillery Rocket Systems, Expeditionary Fire Support Systems, tank systems, information-related capabilities and radar systems to accomplish their warfighting mission.

Le déficit carabiné des États-unis va le freiner. 

Il ne pourra pas faire grand chose ici car les infrastructures seront prioritaires. Les dépenses militaires ne relancent pas une économie.

On verra si avec la Moumoute qui veut réaugmenté l'effectif de l'USMC si le sort des LAV va être chamboulé. Il est possible que plus d'engins soit remis a neuf.

@collectionneur@Serge .


Oui il est peut-être temps qu'ils remplacent leur LAV , Les engins commencent à fatiguer !
