In today’s operational environment, nothingis certain except for uncertainty. The demandsposed by an evolving threat and challengingterrain make it essential that light tacticalvehicles are as capable and flexible as possiblein order to complete the full spectrum ofmissions demanded of them. Iveco DefenceVehicles identified this trend early on,undertaking extensive research to identify andquantify the key factors which were likely ordrive the user’s requirements in the conflictsof the early 21st century.

Based on the output of this research, and onthe company’s own extensive experience ofthe market sector, a programme was initiatedto develop an innovative and highly adaptableLight Multirole Vehicle (LMV). The LMV wasdesigned to fill a wide variety of rolesincluding:

Command, reconnaissanceand liaison vehicle

Patrol vehicle, with four dismounts

Light weapon systems platform

Medevac

Logistic carrier

Artillery tractor

Meeting these roles effectively was paramount.Accordingly, the design process began byidentifying the most demanding militaryrequirements and ensuring that thespecification met these in terms of:

Crew protection

Versatility/modularity

Mobility

Payload capacity

Reliability and maintainability

Towing capacity

Low observability

Transportability

Designed to meet the challengesof an uncertain world

Crew protection was accorded particularpriority, reflecting the importance of achievingmission success with the minimum of risk topersonnel.

The protection system is based on a crew cell,or citadel, with the remainder of the vehiclebeing configured around this central feature.

In this weight class of vehicle, blast effect canonly be reduced by venting the blast awayfrom the crew cell and by absorbing andmanaging the residual energy. In order toachieve this, the crew cell is decoupled fromother components, minimising the transmissionof blast energy from the chassis. Both the frontand rear of the vehicle are designed to besacrificial, and can be blown off, enablingfurther mitigation of the blast energy.

The principal driveline assemblies are locatedto the front and rear of the vehicle, preventingthem becoming secondary projectiles in theevent of a mine blast. The integrity of thecrew cell is maintained through a series ofdesign features. The bonnet is hinged to thechassis rather than the crew cell, and the rearcargo compartment and fuel tank are sodesigned that they will readily blow off, againallowing blast energy to dissipate.

The fuel tank is filled with explosivesuppressant foam and the filler cap ispositioned as far as possible from the doorsto the crew cell further reducing risk in caseof fire. The crew cell is unprotected in its basicform, with protection being afforded by aseries of composite armour ‘skins’. Dependingon which is fitted, these provide a variety ofprotection levels which can accordingly beadapted to meet the predicted threat.

This protection solution exploits the latestarmour developments and can be redesignedto incorporate further innovations as thesebecome available, so future proofing theprotection solution.

By virtue of an innovation patented by IvecoDefence Vehicles, the Customer can readilychange the level of protection within the spaceof a few hours, even under field conditions,by replacing ballistic panels which fit betweenthe internal structure and the outer cladding.This greatly facilitates replacement andupgrading of protected panels compared withmonocoque vehicles.

The protection levels provided by the ballisticglass in the windows can also be increased toa level commensurate with the opaque armour,whilst maintaining the vehicle’s external profileand inherent low observability.

The vehicle can accordingly be fitted withLight, Medium or Heavy protection kits,depending on the mission profile - for example,on lower risk missions, a light protection kitcould be used to maximize the payload. Onmissions judged to pose a higher risk,additional protection can be provided up toSTANAG 4569 Level 3 (ballistic) and Level 2a(mine).

The general design features which contributeto the protection of the crew against mineattack, are complimented by a highly effectivesystem of protection for the crew citadelagainst mine blast. This incorporates a multi-layered floor structure designed to manageand absorb both blast and fragments fromsmaller mines, with protection against anti-tank mines being provided by the installationof a blast shield.

Effective management of the blast energythrough dissipation and absorption is achievedthrough a series of design features

Large tyres fitted with run-flat inserts provideabsorption, whilst dissipation is enhanced bythe fitting of deflectors along the wheel arches.All occupants are provided with speciallydesigned shock dampened seats which aresuspended on elastic mounts, avoiding directtransmission of blast shock to the crew. Theseats incorporate moulded padding and five/sixpoint seat harnesses to reduce sudden bodymovements caused by both the primary (rising)and secondary (falling) effects of blast, andpossible negative “G” in the event of roll-over.Specially designed wrap-around head-restsprovide protection from whiplash in case ofRoadside IEDs.

The roof of the LMV is readily adaptable tocustomer requirements and can be fittedwith hatches that can be opened from insideor outside.

A weapon ring mount or protected cupolacan be mounted on the vehicle roofstructure, carrying a variety of weaponsdepending on the customer’s need.

A remote weapon station is an increasinglypopular option, with no fewer than 5different models being mounted on theLMV fleet by different customers.

Internally, different types of roll bar areavailable, providing the vehicle’s occupantswith roll-over protection and withstandingacceleration up to 7.5 g.

Particular care has been taken to provideergonomically sound and comfortableworking positions for all occupants. Thevehicle complements this by providing highlevels of vibration control and shockabsorption.

The vehicle’s controls are designed to providethe perfect balance of automation andlightness of touch, making the vehicleresponsive and easy to handle.

The LMV is an extremely mobile and agilevehicle which is capable of operating across awide range of demanding terrains. It is alsowell adapted to operations in demandingclimatic environments, within temperatureextremes of -32oC to +49oC including highhumidity.

The vehicle’s particular mobility featuresinclude:

Independent suspension.

Permanent four wheel drive.

ADM (Automatic Drive-Train Management)as an option.

ABS system designed specifically for on/offroad conditions.

Air-over-hydraulic braking system, allowingrapid braking even when heavily laden.

Mechanical hand-brake allowing immediatemovement when required.

A 140 kW (190 HP) engine delivering apower to weight ratio of some 20 kW/T.

A six speed automatic gearbox with hydro-dynamic coupling converter with two geartransfer-box (flanged to the rear differential).

Central Tyre Inflating System (CTIS) allowingthe tyre pressure to be adjusted to terrainconditions from within the cab and while onthe move.

The transfer-box is integrated in the reardifferential therefore allowing better weightdistribution, an underneath flat floor andallowing optional mine blast resistance.

One of the key innovations which has beenmade in the drive train is the adoption ofinboard brakes positioned near thedifferentials and fixed elastically to the chassis.This reduces the unsprung mass of the vehicle,so enhancing performance, whilst alsosignificantly increasing protection from anti-personnel mine blasts and fragmentation.

Mobility Operational and Tactical

LMV’s overall configuration takes full accountthe joint requirements of protecting againstmine blasts and negotiating obstacles.

Features which contribute particularly to thevehicle’s exceptional mobility include:

High approach and departure angles.

Excellent ground clearance.

Independent suspension with long travel.

High level of stability on longitudinal andtransverse slopes.

325/85R16 tyres or 335/80R20 with CTIS,providing an excellent mean maximumpressure (MMP).

CTIS with electronic pressure regulation andmonitoring, ensuring outstanding terrainaccessibility.

Tyres high traction.

High power-to-weight ratio combined withcompact size ensures ease of use on mountainstracks and public roads alike.

Reduced turning circle.

Large wheels in combination with automatictransmission, locking differentials, 2 speedtransfer case and independent suspensionsystems enable use in extreme off-roadconditions.

In its basic configuration, LMV is capable offording depths of 0.85 m unprepared by virtueof its waterproof electrical system.

As an option, this can be extended to a depthof 1.5 m under STANAG 2805 conditions byadding extensions to the air intake andexhaust.

For night driving, the vehicle is designed tobe compatible with thermal imaging drivingaids and NVG.

LMV’s weight and size ensure that it is highlytransportable:

By rail transport on standard flatbeds.

By RO-RO ferry.

By air, with two LMVs with a full battle loadfitting onto a C130J. LMV can also betransported by heavy strategic airlift such asC-5, C-17, A400M.

By helicopter, underslung from a CH47. LMVis also airdroppable on a suitable platform.

Transportability Strategic MobilityHigh reliability, ease of maintenance and lowthrough life costs were key considerationsduring the design of LMV.

The vehicle benefits particularly from Iveco’sengineering experience on its truck rangewhich has allowed incorporation of a numberof innovative design features.

The use of COTS main assemblies such as thegearbox and engine ensures that performanceand reliability have been proven over manymillions of road miles in demandingenvironmental conditions. This provides anoutstanding level of reliability andconsequently excellent fleet availability.

The design has led to a reduction in Level 1maintenance requirements.

LMV is fitted with a 2nd generation high speedCANBUS which links the electronic controlunits of the engine, gearbox and ABS. Byinterrogating the system with a diagnostictool, the maintainer can gather diagnostic andprognostic information in real-time, enablingpre-emptive maintenance to be planned.

Ease of maintenance has received a very highpriority, with ready access being provided toundertake checks and routine servicing tasks,and maximum use being made of repair byreplacement. All Level 1 checks can be carriedout by the crew without dismantling any majorassemblies, or using special tools.

An innovation designed to allow the crew tomove out of immediate danger, even whenthe vehicle has malfunctioned, is the limphome facility. This is controlled by an onboardsystem integrated into the enginemanagement software and is aimed atallowing a sufficient degree of mobility, albeitwith limited power, in the event of an onboardautomotive system or sensor malfunction. Anover-ride facility is also provided for this device.

The ability of the LMV design to accommodatethe variety of design developmentswhich are demanded by the user has enabledIveco’s engineering team to implementthe vehicle family approach which has alwaysunderpinned the LMV design concept.

By monitoring and anticipating the user’sneeds, and exploiting best engineeringpractice to meet them, Iveco has ensured thatthe LMV will continue to expand theroles it can undertake, moving seamlessly intothe field of protected utility vehicles.

The evolving demands of the user broughtIveco’s engineering team to focus on a longervariant derived from the standard LMV, witha 3520 mm wheelbase design. Besides enablingmore room to be provided in the crew cell,this variant can also incorporate a longerstowage pod, substantially increasing thevehicle’s capacity.

New design features include an integral hardtop in place of a roll cage, altering the roofhatch design, incorporating new seats andchanging the design of the transparentarmour. At the same time, the allowable GVWof the vehicle has been increased from 7,000to 7,500 kgs through developments on theframe, brakes and suspension.
