10.5t and a road speed of 66kph powered by a GM V6 diesel. The crew
varied between 2 and 10 depending on the role of the vehicle.
The M113 fleet comprises a total of 766 vehicles; of which 431 are AS3/4
versions and the balance are A1 versions. The presently scheduled expiry
date of the AS3/4 vehicles is 2020.
Variants to the baseline M113 have been prolific. LAND 106 was endorsed
by Government in the 2000 Defence White Paper to provide a major
upgrade of 350 of the Army’s in-service M113A1 vehicles. Approval to
upgrade a further 81 vehicles was approved by Government in 2008,
bringing the total to 431 vehicles to be upgraded to the M113AS series.
The objectives of Land 106 are to extend the LOT of this series and to
provide significant enhancements in protection, lethality and mobility
while also providing improved supportability.
Seven variants of the M113AS series are being produced. These are:
Armoured Personnel Carrier (M113AS4 APC); Armoured Fitters (M113AS4
AF); Armoured Recovery Vehicle Light (M806AS4 ARVL); Armoured
Ambulance (M113AS4 AA); Armoured Mortar (M125AS3 AM); Armoured
Command Vehicle (M113AS4 ACV ); and Armoured Logistic Vehicle
(M113AS4 ALV Armoured Personal Carrier (APC). The APC can carry an
infantry section and, when the rear ramp is lowered, passengers can enter
or exit the vehicle quickly. In its class it is perhaps the most valuable APC
used by the Army.
The enhancements are being achieved as follows:
Protection will be significantly enhanced with the addition of appliqué
armour and spall curtains as well as a number of changes designed to
enhance the vehicle’s mine protection. It must be noted though, that The
M113 has a flat bottom.
Lethality will be increased with the incorporation of a totally new
electrically powered turret. The turret will be fitted with a quick-change
barrel machine gun and a new day/night gun sight.
Mobility will be provided by a new engine, transmission, drive train
and driver’s controls. To maximise the benefits of this new driveline the
suspension, track and road wheels are also being replaced.
Supportability improvements include new electrical and fuel systems,
improved habitability and a range of new stowage layouts to meet the
diverse requirements of the numerous user units.
There is a further upgrade of the AS3, designated as AS4, with the two
build standards and carrying capacity being differentiated by the overall
length of each of the two vehicles. The AS3 variant has five road wheel
stations per side and a recommended gross vehicle mass (RGVM) of 15000
kg. The AS4 variants have been stretched by 666 mm, with an additional
road wheel station per side and a RGVM of 18 000 kg.
LAND 112, ASLAV
ASLAV is the Australian designation of the LAV-25 produced by GMDLS
Canada with the original design being drawn from the MOWAG Piranha
The ASLAV Acquisition Program has four phases, of which three are
15 LAV-25s ex US Marine vehicles were purchased in 1990 by
Defence to trial the Wheeled Armoured Fighting Vehicle concept in
Northern Australia. The adoption of such a vehicle was supported, but
some shortcomings for the Australian Army application were evident.
approved August 1991 and contracted to the “Canadian
Commercial Corporation” (CCC) in December 1992 for 97 vehicles. The
contract scope was increased to 111 to provide for the replacement of
the 15 Ph. 1 vehicles. These vehicles were designated ASLAV. Also under
this phase three hull types to provide the basis for seven variants were
specified as follows:
- a turreted vehicle with a 25mm stabilised cannon and
thermal imaging weapon system. It is used for only one variant the
has greater internal capacity and no turret. Using a
common hull design installed with unique Mission Role Installation
Kits, it provides the Personnel Carrier, Command, Ambulance and
allows for the installation of a crane for the Fitter
(repair) variant or a heavy winch and support stands for the Recovery
variant, again each with its own Mission Role Installation Kits.
approved December 1997. 144 vehicles were ordered to give a
total number of 257 vehicles. Ph.3 . also included significant Australian
content, an upgraded EOS, a new turret, improved suspension and
crew airconditioning and was back-fitted to the Phase 2 vehicles. Turret
equipment, not included in the Prime contract, included the “Behind
Armour Commander’s Weapon Station (BACWS)” achieved through the
purchase of a Remote Weapon Station (RMS) from Kongsberg through
a series of acquisitions. By December 2005 all 59 Remote Weapon
Stations had been delivered on schedule and installed in ASLAVs by
The Multi-Spectral Surveillance System (MSSS), originally part of the
Prime Contract, was purchased direct from DRS. It is a reconnaissance
and surveillance package consisting of a laser rangefinder, thermal imager,
and ground surveillance radar integrated with a stabilized common gimbal
(SCG-100) and soldier machine interface provided by DRS. The MSSS is
capable of three modes of operation: mounted on the vehicle, connected
to the vehicle by a cable, and completely dismounted. The MSSS package
will be designed as a kit for installation on the ASLAV-S.
Second Pass Government approval on 01 June 2010. It will
address enhanced survivability, a half-life upgrade and standardisation
of the ASLAV fleet. Possible survivability enhancements against current
and future threats include:
containers, special tools and test equipment, consumables and other
repair parts; and training and provision of technical documentation.
the Crew Procedural Trainer are included in Phase 4.
113 ASLAVS are presently scheduled for Phase 4 with delivery
commencing April 2012.
It is notable that the Army has opted to maintain the ASLAV’s “swimming”
capability and mobility. Retaining these capabilities requires close
attention to the vehicles’ AUW and CG when any addition is proposed
that changes the vehicles’ mass and balance characteristics beyond those
approved by the Design Authority GMDLS Canada, particularly adding
armour protection. This has resulted in ASLAVs being fitted, amongst other
considerations, with a lightweight ‘cage’ designed to trap armour piercing
munitions before they hit the hull and low mass spall liners.
