In the Defence White Paper of March 1987, the Government
stated that Australia’s northern defences would be strengthened.
For the Australian Army, this would be first achieved by basing a cavalry
(reconnaissance) regiment in the Darwin area, beginning in 1992.
The regiment would be tasked with mobile reconnaissance and surveillance
over a wide area, and would have its capability expanded with the acquisition of
new equipment. In particular, a new wheeled armoured vehicle was to be given
consideration, based upon the large distances which had to be covered during any
type of ground reconnaissance or surveillance mission in Northern Australia.
By
late 1988, the Wheeled Armoured Fighting Vehicle project (WAFV) was underway,
with the main contenders under consideration being the GM Canada LAV25, the
Steyr Pandur and the Saviem VAB. However,
in an unprecedented move in 1989, the Australian Government approached the US
Government about a direct purchase of vehicles from United Sates Marine Corps
Stocks. In 1989 the purchase was
approved, and the Australian Army ordered 14 LAV-25’s and one LAV Recovery
from USMC Stocks. These vehicles
were to be used for evaluation over a two year period, and were used for
organisation trials, validation of employment in Northern Australia and a
comparison of performance with existing tracked light armoured vehicles (the
M113A1 family).
The USMC vehicles arrived by ship in Newcastle in April 1990, and were transferred to the 21 Supply Battalion depot at Moorebank, south west of Sydney. An inspection revealed that a number of the vehicles were suffering from severe water damage, probably having been transported as deck cargo. The vehicles were dried out and repaired, and issued to the 2nd Cavalry Regiment, Royal Australian Armoured Corps, then based at Holsworthy. After familiarisation training had bee conducted withing the Regiment, the vehicles were first deployed to Northern Australia in October, 1990, and operated during the hot-dry season where temperature inside the vehicles reached around 55°C. This first exercise saw vehicles covering some 6500km, with one troop returning from Tindal to Sydney, some 4000km, on their own wheels. During the evaluation period, several deficiencies were found in the vehicles for use under Australian conditions - the tyres were easily staked by the bush in the north of Australia; the vehicles were exceptionally hot inside during daytime operations (true of any AFV in that climate) and some of the hull fittings were easily damaged. The tyre problem was a constant one, and was solved by the carriage of one or two spare wheels complete, mounted on a hinged carrier frame on the rear of the hull. Although they blocked the rear doors from use, the LAV25 was never considered in Australian service to be anything other than a reconnaissance vehicle.

Four
Canadian Bison Armoured Personnel Carriers were evaluated in 1992 as part of the
ABCA (America, Britain, Canada and Australia ) loan agreement, and with their
larger hull giving a roomier interior, were found to be more ideal for the
carriage of Assault Troopers than the LAV.
(These vehicles were returned to Canada at the end of the evaluation
period.)
After
almost two years of trialing, it was announced in December 1992 that Australia
would purchase 97 LAV’s from Canada, to supplement the 15 vehicles already
held. The vehicle family was
designated ASLAV – Australian Light Armoured Vehicle - (AS is the NATO
abbreviation for Australia), and the purchase of 97 vehicles was to be made up
of:

The
ASLAV hulls with automotive components and fitted with the turret for the gun
versions were built in Canada, and then sent to Adelaide, South Australia for
fitting out by British Aerospace Australia, the local sub-contractor of Diesel
Division General Motors of Canada. The ASLAV is an eight wheeled vehicle, with
the front two axles steering, and having the ability to operate in either four
or eight wheel drive. Rear mounted
propellors give the vehicle a speed of 10 km/hr in water.
The turbocharged GM 6V53T diesel engine gives a top road speed in excess
of 100 km/hr. A range of 600
kilometres is possible. A front
mounted self-recovery winch is fitted.
The
standard vehicle of the family is the ASLAV-25, the reconnaissance variant. Its
Delco designed turret mounts the M242 25mm
Cannon, which has a selectable rate of fire varying from single shot to
100 and 200 rounds per minute. Two
MAG 58 7.62mm Machine Guns are fitted, one co-axially with the M242 and the
second on the turret for use by the commander.
A thermal imaging day/night sight is fitted. The turret rotates 360º and
is fully stabilised.

Although
the vehicles use the LAV basic hull, the protection level can be increased by
the addition of ceramic armour tiles. The
purchase of this additional armour is currently deferred.
Crew protection is increased by the fitting of a automatic fire
suppression system.
The
ASLAV specification included a climate control system for the crew compartment
and the fitting of Australian made Raven radio equipment. Michelin XML tyres are
fitted, larger in diameter and
cross – section than the original tyres, and with a more aggressive tread
pattern. Vehicles carry a puncture repair kit to allow speedy tyre repair.
Different exhaust system, guards for the propellers, different external stowage,
different turret stowage, improved barrel for 25mm gun, infantry/tank telephone
and differing aerial mounts are some of the many other detail differences which
exist between the original LAV and the new ASLAV vehicles.
The variants of the ASLAV Family are based on three
distinct hull types. The Type 1
hull is the standard vehicle with turret. The
Type 2 hull has no turret but a higher rear superstructure, and is the basis for
the Personnel Carrier, Command, Surveillance, Ambulance and Logistic variants.
The Type 3 hull is similar to the Type 2 but is strengthened to allow the
mounting of the Fitters and Recovery configurations.
The Type 2 and Type 3 hulls are fitted with Mission Role Installation
Kits (MRIK) which are non-permanent, so that several variants can be configured
from the same hull type. These
Australian developed kits can be installed and changed at the unit level. The variants will be described in the next article.
The first vehicles arrived in Adelaide in February 1995, with instructor and crew training taking place at the School of Armour, Puckapunyal, from October 1995 until the end of 1996. The 2nd Cavalry Regiment became fully operational by 1997 with some 86 ASLAV variants equipping the unit. The remaining vehicles of the 97 total equip the Mounted Combat Division (MCD) of the Army Combined Arms Training Centre (ACATC), formerly the School of Armour, at Puckapunyal and the Army Logistic Training Centre in Bandiana.
The
first big test of the ASLAV Family came during Exercise Phoenix, which was the
culminating event in the
Restructuring of the Army Task Force. The
exercise was held in the Northern territory, in an area of some 200,000 square
kilometres. Emphasis was placed
upon the aquisition of intelligence, the main gatherer of which was the 2nd
Cavalry Regiment and their ASLAVs. In
this role they were highly successful. The
vehicles’ ability to deploy quickly over very long distances, and their
day/night operating capability, proved their worth.
The
exercise also trialed a number of vehicles, including the DDGM 120mm Armoured
Mortar System and a TOW anti-armour missile turret mounted on an ASLAV hull.
Along with a Paladin 155mm Self Propelled Gun and a Palletised Load
System (PLS) resupply vehicle, they gave the Australian Army a close look at
these modern battlefield systems in an operational environment.

litre water can is stowed in the rack on the hull. |
September
1999 saw the Australian Army involved in its biggest operational deployment
since the war in South Vietnam, when it responded to the United Nations request
for a peacekeeping force to be involved in the independence of East Timor from
Indonesia. Some 5000 Australian
troops were deployed, including a composite squadron from 2nd Cavalry
Regiment. Although trained as a
reconnaissance organisation, the squadron was deployed as an APC unit, having
only four ASLAV 25 vehicles, the remainder being mainly the APC variant.
Phase 3 of the ASLAV project will be the purchase of a
further 150 vehicles, sufficient to equip another two regiments.
At present the planning is for an in-service date of 2004
The ASLAV-25 is the base vehicle of the family. As noted previously, all variants currently in service are based upon the Type 2 and Type 3 hulls. However, the MCD has one variant of the ASLAV-25, this being the Driver Training vehicle.

Training vehicle from the side-rear. The Driver
Training Turret retains its Canadian Army green camouflage paint. |
It is a standard
ASLAV-25, with the Delco turret removed and a cabin fitted in its place.
The cabin seats two personnel in comfortable “armchairs”, and has two
roof hatches,radio aerial mounts and windscreen wipers.
The cabin fits directly on the turret ring of the ASLAV-25, but does not
rotate. The Delco turrets when removed are placed on stands and used
for the training of crew commanders and gunners, so that one vehicle can provide
training for three AFV trades.
The ASLAV family usually carry some generic markings, such as the ARN, bridge
classification and “Caution Left Hand Drive” warnings, as well as special to
unit markings. The ASLAV-25 (Type 1
hull) carries ARNs in the range 16001 to 16100 in black on the right front
angled upper nose plate and on the left rear door. The Bridge Classification
sign, 15 in black inside a broken circle is below the front ARN. Vehicles of the
2nd Cavalry Regiment normally have an inverted black triangle on the
rear door and the turret sides, together with the radio callsign (C/S), for
example 12B, with the numerals and letters on different sides of the triangle.
(The inverted triangle used by 2nd Cavalry Regiment dates back
to the Second World War, when Armoured Brigade Reconnaissance Squadrons carried
an inverted triangle marking, denoting their independent nature and their recon
role.
All ASLAVs are finished in the standard Australian Army
three colour camouflage scheme.
