M113 into the next Millennium
More than 80,000 M113 Family of Vehicle (FOV) systems have been produced over the past 34 years. As of this writing, new M113 FOV systems are being built while existing chassis are being upgraded to modern configurations.

Since their initial introduction in 1960, M113-based systems have entered service in more than 50 countries. The systems have been modified into more than 40 identified specific variants, with many times that number of minor field modifications. Many of these modifications have been developed by foreign governments to meet their specific national requirements. While some older M113 derivatives are being retired and removed from selected inventories, other FOV members are being upgraded, reconfigured, and introduced as entirely new systems.
The original M113 Armored Personnel Carrier (APC) helped to revolutionize mobile military operations. The vehicles were able to carry 11 soldiers plus a driver and track commander under armor protection across hostile battlefield environments. More importantly, the new vehicles were air transportable, air-droppable, and swimmable, allowing planners to incorporate APCs in a much wider range of combat situations, including many "rapid deployment" scenarios. The M113s were so successful that they were quickly identified as the foundation for a family of vehicles. Early derivatives included both command post (M577) and mortar carrier (M106) configurations.
The first major upgrade came in 1964 with the introduction of the M113A1 package which replaced the original gasoline engine with a 212 horsepower diesel package. The new power train was soon incorporated into the existing vehicle family as the M113A1, M577A1, and M106A1, as well as several new derivative systems. Some of these new derivatives were based on the armored M113 chassis (the M125A1 mortar carrier and M741 "Vulcan" air defense vehicle) while others were based on an unarmored version of the chassis (including the M548 cargo carrier, M667 "Lance" missile carrier, and M730 "Chaparral" missile carrier).
Continuing modernization efforts led to the introduction of the A2 package of suspension and cooling enhancements in 1979. As with previous enhancements, these upgrades resulted in further proliferation of the FOV.
Today's M113 fleet includes a mix of these A2 variants together with other derivatives equipped with the most recent A3 RISE (Reliability Improvements for Selected Equipment) package. The standard RISE package includes an upgraded propulsion system (turbocharged engine and new transmission), greatly improved driver controls (new power brakes and conventional steering controls), external fuel tanks, and 200 AMP alternator with 4 batteries. Additional A3 improvements, include incorporation of spall liners and provisions for mounting external armor.
The future M113A3 fleet will include a number of vehicles that will have high speed digital networks and data transfer systems. The M113A3 digitization program supports the Army's Modernization Plan by applying applique hardware, software, and installation kits and hosting them in the M113A3 FOV. Current plans call for these systems to be integrated into the M113A3 FOV by the year 2006.

Engine Upgrades
A major component of the RISE powertrain incorporated into the original M113A3 and M730A2 vehicles is the turbocharged 275 hp 6V53T engine from Detroit Diesel Corporation. Replacing the earlier 212 hp M113A2 engine with the turbocharged 275 hp model paved the way for improvements in performance as well as survivability enhancements such as the incorporation of spall liners and the possible addition of add-on armor. The improved performance and higher chassis load capacity has also opened the way for planners to consider additional M113 FOV derivatives.
Moreover, industry and government initiatives have revealed that the RISE engine rating can be increased to 300 hp through the conversion of injectors. Further testing is currently being conducted on a possible engine upgrade to 350 hp (6V53TA-350 hp) while still retaining the X-200-4A transmission. This additional upgrade requires the installation of glow plug heads (eliminating the need for the current air box heater) as well as changes to the air system and a few other components. The glow plug cold starting system also provides for improved engine starting down to -25°F unaided while utilizing 85 percent less battery power during cold starts (the cold starting system is adaptable to the M113A1, M113A2, and M113A3 engines). The glow plug system is now being installed in the 275 hp RISE engine. Initial testing indicates that the 350 hp engine retains the same external envelope size with a gain of only 45 pounds in weight. The higher horsepower makes a heavier vehicle possible; allowing heavier mission payloads and/or greater armor protection.

Transmission Upgrades
The new engine packages have also been accompanied by improvements in the RISE transmission component. The RISE program was introduced with the X200-4 transmission from Allison Transmission. The X-200-4 transmission replaces the three component A2 vehicle drive train (transfer gear case, transmission, steering differential). The new transmission, designed to provide longer life than the previous configuration, has proven durability that is five times greater than the TX-100-1 transmission that it replaced.
The Model X200-4 Transmission went into production in 1986 for both the M113A3 and M730A2 RISE powered vehicles. It was designed for use in vehicles up to 32,000 pounds, a top speed of 41 mph, a maximum engine speed of 2800 RPM, and a power rating up to 275 hp.
Development of the Model X200-4A Transmission was prompted by the heavier derivative vehicles that will utilize the 300 hp and 350 hp engines noted above. The "4A" model features durability and performance improvements in 6 separate areas. It is capable of operating in vehicles up to 40,000 pounds with a top speed of 41 mph. Most importantly, the new model allows for vehicle power growth up to 350 hp. Because of its application from 275- 350 hp, the X200-4A has been phased into production and is the only transmission currently being produced for the M113A3 RISE variants.

M113A3
The M113A3 is a product improved version of the M113A2 with improved transmission and engine. The U.S. Army first identified the need to up-power the M113A2 carrier in the mid-1970s. This need was driven by increases in vehicle weight and a requirement to increase the mobility and survivability of the system. As a result, the "RISE" powertrain was developed and tested at Yuma and Aberdeen Proving Grounds. However, application of the new powertrain was deferred due to a lack of funds.
In 1984 a decision was made to incorporate the RISE package, improved driver controls, spall liners, external fuel tanks and provisions for installation of an external armor kit on an M113 chassis. Additionally, a bolt-on armor kit providing 14.5 mm ballistic protection was developed and tested. Except for the mounting provisions the external armor applique was not incorporated for production.
The new X200-4/4A hydrostatic steer transmission permits use of a more powerful engine, the 275 HP turbocharged Detroit Diesel 6V53T, and eliminates the transfer case and controlled differential. The RISE powerpack increases fuel economy, acceleration, hill climbing speed and braking capabilities and allows the vehicle to maintain speed through corners by accelerating the outer track rather than braking the inner track as on the A2. The increase in horsepower also allows installation of an external armor kit (which increases the gross vehicle weight to 31,000 pounds) and provides mobility comparable to currently fielded vehicles such as the M1 tank and M2/M3 Bradley Fighting Vehicles.
Steering is improved with an automotive-type steering yoke and foot brake arrangement which improves driver control, lessens fatigue and simplifies driver training from that of the A1/A2 steering/braking laterals. Due to load matching ability and increased steering capability, cross country performance is also improved.
Crew survivability is increased by the addition of spall suppression liners and locating the fuel tanks externally, on the rear of the vehicle. The inside of the vehicle (sides, roof and rear) are covered with spall suppression liners which limit troop injuries from the effect of overmatching weapons by restricting the spread of spall when a round penetrates the hull. External fuel tanks free up 16 cubic feet of usable space inside the vehicle and reduce the fire hazard inside the crew compartment. Two tanks and independent valving provide redundancy in the fuel system allowing continued operation when one tank is damaged.

Photos of new Lynx KF31 Light Armored Infantry Fighting

Jun 14, 2016

 
The Lynx is a  light armored infantry fighting was designed by Rheinmetall.


Lynx features a Rheinmetall LANCE turret armed with a stabilized, externally powered, airburst-capable automatic cannon (either 30mm or 35mm). This enables Lynx to effectively engage targets with high precision at ranges of up to 3,000 metres – even on the move. Lynx can also be equipped with an antitank guided missile launcher and a secondary weapon station linked to the main optics (main sensor slaved armament).

Not only does Lynx have hunter-killer capability, it can operate in killer-killer mode, since the commander and gunner can observe and engage targets independently of each other.

The vehicle’s ballistic armour shields Lynx from antitank weapons, medium-calibre ammunition, artillery shrapnel, IEDs and bomblets. In addition, a spall liner in the vehicle interior protects the entire crew. Mine and IED protection packages, decoupled seats and the optional hard kill Active Defence System (ADS) significantly boost the vehicle’s survivability.

Lynx features an excellent power-to-weight ratio and can handle gradients of up to 60 degrees and lateral inclines of more than 30 degrees. It can cross ditches up to 2.5 metres wide and ford bodies of water up to 1.50 metres deep. Furthermore, it can climb over one-metre-high obstacles. The vehicle can run on either rubber or light metal tracks.




Another characteristic of Lynx is its versatility. For example, the new IFV comes in two versions: the KF31 and KF41 (KF stands for “Kettenfahrzeug”, or tracked vehicle in German). Weighing up to 38 tonnes, Lynx KF31 on display at Eurosatory and can seat 3+6 soldiers. Lynx KF41 is slightly larger and can carry 3+8 soldiers. Both vehicle classes – Lynx KF31 and Lynx KF41 – can be configured for other roles include a command & control, an armoured reconnaissance, repair & recovery and an ambulance.

Lazar-3 multirole armored vehicles

Read news from Defence Blog at Flipboard.com | Subscribe to the newsletter from Defence Blog

Serbian state-owned defence company Yugoimport has successfully demonstrated the capabilities of the Lazar-3 multirole armored vehicle during a visit of Defense Minister Aleksandar Vulin and Chief of General Staff of the Army of Serbia General Ljubiša Diković on the “Nikinci” military range.

Lazar 3 is a new Serbian armored wheeled vehicle designed for various applications and missions. Lazar 3 has a highly sophisticated, modular ballistic protection. The hull is made of armored steel and can be fitted with a spall liner.

The applied ballistic protection can be tailored to the specific needs of the user and allows for application of additional state-of-the-art ballistic protection technologies throughout the vehicle service life.

The vehicle floor has two levels of anti-mine protection. It is capable of sustained speeds of 110km/h on level roads.

Dimensions and weight

• Length: 7920mm
• Width: 2950mm
• Height (without turret): 2320mm
• Clearance: 420mm
• Approach angle: 45°
• Departure angle: 38°
• Wheel base: 2530mm
• Spacing between axles: 1500mm-1800mm-1450mm
• Engine space: 5m³
• Crew space: 15m³
• Combat weight (depending of mission and protection): 22-26t
• Max. weight: 28t

The number of the crew depends on the type of a mission and the weapons used in the vehicle. When the vehicle is equipped with the remote control weapon station (RCWS), the vehicle should be manned with 12 troops (commander, driver, gunner + 9 soldiers), while the version with a turret would be manned with one soldier less.

The Lazar 3 vehicle has a remote control weapon station (RCWS), which can be armed with one 30mm M86 automatic cannon or one 7.62mm M86 co-axial machine gun or one anti-tank guided missile (ATGM) for protection against light armoured vehicles, military installations and low-flying air targets.

The U.S. Army’s Bradley Fighting Vehicle Might Get Even Bigger

Sebastien Roblin
The M2 Bradley infantry fighting vehicle is nominally used to carry infantry into battle, but is frequently misidentified by journalists as a tank. This is understandable, as the tracked vehicle currently tips the scales at 33 tons from all the add-on armor it has received, and bristles with both a 25-millimeter Bushmaster automatic cannon and a TOW anti-tank missile launcher.

Oddly, critics of the vehicle have sometimes complained that the Bradley’s sheer firepower often makes the soldiers it carries onboard an afterthought. In theory, the onboard mechanized infantry squads are supposed to dismount in denser terrain to scout out enemy positions and ambushers, maintain defensive perimeters, and flush adversaries out of buildings and other built-up areas that the Bradley can’t reach.

However, a notable limitation of the M2 as a troop transport is that it can carry just seven dismounts — in earlier models, just six — while a mechanized infantry squad currently has nine. Each mechanized infantry platoon therefore has to divide three squads between four Bradleys, meaning that all the members of squad are not able to ride in the same vehicle.

The Army is halfway through a two-stage update process for its roughly 1,800 remaining M2 and M3 Bradleys, to restore automotive power to the chassis and upgrade its computer systems to be more accommodating of future improvements. In January 2018, it emerged that an even more ambitious M2A5 upgrade is being planned for the mid-2020s, which might stretch out the hull to carry more armor and personnel and install a more powerful 30-millimeter cannon turret.

That’s right: the Army’s biggest and baddest troop carrier might get even bigger.

More punch for AMV [IDEX19D1]

CHRISTOPHER F FOSS

17 February 2019




Patria of Finland is showing its latest Armoured Modular Vehicle (AMV) XP fitted with the Italian Leonardo Defence Systems HITFACT 120mm turret system for the first time (Stands 10-C09 and B10). This combination will provide potential customers with a highly mobile anti-tank capability, which can be rapidly deployed over long distances without the need for heavy equipment transporters (HETs), which are required for tracked vehicles with a similar capability.

The AMV XP has been developed by Patria to meet requirements for a 8x8 vehicle with extra payload, performance and protection. It is being marketed alongside its combat-proven standard AMV (8x8), which has now been sold to seven countries.

Nearly 1,600 AMVs are on order or have been delivered – more than 95 per cent for the export market.

Development of the AMV XP is complete and production can commence when orders are placed.

AMV XP has a gross vehicle weight of up to 32 tonnes and is fitted with a modular passive armour package that can provide protection up to STANAG 4569 Level 4+. It is powered by a Scania DC-13 in-line diesel developing 612hp coupled to a ZF 7HP 902 Economat automatic transmission, which gives a maximum road speed of 100km/h. With the 500-litre fuel tank, road range is up to 1,000km. Steering is powered on the four front wheels, and power steering is optional on the rear axles.

The Leonardo HITFACT 120mm turret has been ordered by the Italian Army for installation on its latest Centauro II Mobile Gun System, but its design is such that it can be fitted to a wide range of tracked and wheeled platforms. It is armed with a 120mm L45 high-pressure, low-recoil smoothbore gun than can fire standard NATO ammunition, including armour-piercing fin-stabilised discarding sabot (APFSDS) and the recently developed Rheinmetall DM11 programmable high-explosive (HE) round.

Mounted co-axial with the 120mm gun is a 7.62mm machine gun (MG) and a remote weapon station is on the roof, armed with a 7.62mm or 12.7mm MG and a pintle-mounted MG. A computerised fire control system is fitted, which enables stationary and moving targets to be engaged with a high first round hit probability while the AMV XP is moving.
