DSTA helps develop the All Terrain Tracked Carrier (ATTC)
DSTA - May 2, 2001
The
Defence Science & Technology Agency (DSTA) worked hand in hand with the Army and ST
Kinetics to build an All Terrain Tracked Carrier (ATTC) to augment the Armys
mechanized force.
DSTA
engineers gave valuable inputs in the following areas of expertise:
1.
Programme management
The project
management team from DSTA managed the development of the ATTC and ensured that it is
delivered to the Army on time and on budget. Activities carried out by the team included
specifying technical requirements, reviewing designs and conducting evaluation trials.
The DSTA project team
was able to achieve synergies in the development of the ATTC, as members contributed
significantly in their areas of specialization.
2.
Ergonomics
DSTA harnessed human
factors engineering (HFE) to enhance the human effectiveness, comfort and safety of the
ATTC. A well-designed man-machine interface considers factors such as leg clearance, body angles and
functional arm reach to ensure crew comfort, reduce crew fatigue and get the best possible
human performance when using the ATTC. To ensure that SAF
servicemen can carry out their duties effectively, studies were carried out to
optimize the man-machine interface.
For example, visual contours were
mapped and analyzed based on the seated eye position to study the field of vision for the
driver and commander . The results were used to improve the design of the windscreen and
side windows. iterative prototyping
and innovative mock-ups were used in the design of the drivers seat and the layout
of the instrument displays. structured
questionnaires were used to get feedback from SAF servicemen during the design and
development phases to ensure that the user-system interface conforms to the required human
factor requirements. Even environmental
ergonomics was studied. DSTA engineers measured and evaluated the level of hazards like
noise, vibration, heat and toxic fumes during field trials. Changes in the design of the
ATTC were then introduced to ensure that hazard levels were kept below the safety
threshold.
3.
Communications systems integration
DSTA equipped the
ATTC with a digital intercom system, the first for an Army vehicle platform. This system
is cost-effective and compatible with existing SAF communications equipment.
DSTA carried out
technical evaluations to ensure that the ATTC communications systems can integrate
seamlessly with other sub-systems on the ATTC. DSTA engineers
performed electromagnetic analysis to position radio antennas on the ATTC for
optimal performance.
4.
Weapon integration
DSTA helped select
and integrate weapon systems that meet safety and effectiveness requirements.
Firing acceptance
tests were planned and conducted. DSTA analyzed the results from these tests and
recommended ways to enhance performance and safety of the weapon systems on the
ATTC.
5.
Reliability & Maintainability (R&M) assurance
DSTA saves
operational and support costs by ensuring that the ATTC can withstand harsh military
operating environments and has a high operational availability. Detailed tests were
carried out before the finalization of the design to ensure a reliable and maintainable
ATTC. Failure analysis was
one of the tasks conducted to identify R&M design improvement during developmental
trials.

As part of a determined drive to market its expanding range
of tracked Armored vehicles, Singapore Technologies Kinetics has brought
its new articulated All Terrain Tracked Carrier (ATTC) to Eurosatory.
Singapore Technologies Kinetics only revealed the ATTC in
March this year, so far two preproduction vehicles have been built - one
in a cargo carrier version and the other, shown at Eurosatory, in the
troop carrier configuration. The ATTC comprises two fully Armoured units, front and rear,
connected by a hydraulic articulated joint that features steering and
damping cylinders. The hull is of all welded steel armour which provides
the occupants with protection from 7.62mm small arms fire and shell splinters.
A German IBD passive armour package can be fitted to provide a higher
level of armor protection if required. When being used as a troop carrier, the ATTC can carry a
total of 16 - six in the front, including the driver and vehicle commander,
and 10 in the rear unit, plus their equipment. Maximum quoted payload for the front unit is 1,200kg and
for the rear unit 3,000kg. It is fully amphibious, being propelled in
the water by its rubber tracks at a maximum speed of 5km/h.
For local protection the ATTC can be fitted with a roof-mounted
7.62 or 5.56mm machine gun and banks of electrically operated smoke grenade
launchers. Optional equipment includes a passive night vision system and
a land navigation system. The endless molded rubber bank tracks were developed specially
for the ATTC by Soucy of Canada and are lighter and quieter than conventional
steel tracks. Mounted under the rear part of the front compartment is
the power pack, which comprises a Caterpillar 3126B four-stroke turbocharged
air-cooled diesel developing 350bhp, coupled to an Allison MD 3560P fully
automatic transmission.
Today, the Singapore Armed Forces use the Swedish Hagglunds
Vehicle unarmored Bv 206 for a wide range of battlefield support roles.
It is possible that in the future the new ATTC will gradually undertake
some of these roles as it is not only Armored, but has a significant
increase in load-carrying capability, which enables it to undertake a
much wider range of battlefield roles than the older Bv 206.
In addition to being used as a cargo carrier, other roles
suggested for the ATTC by Singapore Technologies Kinetics include use
as an ambulance, weapons carrier, reconnaissance platform command and
control vehicle, internal security and a number of specialized civilian
roles.

ST
Kinetics Wins Finnish Study Contract
(Source:Singapore Technologies; issued Oct. 25, 2004)
WASHINGTON --- Singapore Technologies Kinetics (ST Kinetics) has been
awarded a study contract in July 2004 by the Finnish Defence Forces
Materiel Command (DFMC) to explore the development of a Future All Terrain
Vehicle (FATV) for the Finnish Defence Force (FDF).
In the contract, ST Kinetics will evaluate new technologies for the FATV,
which is intended to replace the FDF’s current fleet of articulated
vehicles by 2010-2012. The study is expected to conclude by March 2005.
The study contract is an endorsement of ST Kinetics’ extensive
experience and technical competency in the development of both tracked and
wheeled solutions. Its experience with the Bronco All Terrain Tracked
Carrier in particular, has been extremely successful. In fact, the Bronco
has successfully completed exhaustive FDF trials for 6 months in 2003,
covering over 8,000 km of harsh Finnish arctic terrain and weather.
Today, the Bronco has been extensively tested through rigorous sand and
winterisation trials, and has passed the standards set by the US
MIL-STD-810E. It has thrived in hot chamber tests, mobility tests on sand
dunes and alpine snowfields at maximum load. Mobility trials were also
done in elsewhere in Europe, Africa and Asia-Pacific where it is being
actively marketed.
The FATV programme demands a completely new platform - one with challenges
for increased payloads, ability to move continuously at higher speeds and
over longer distances, higher protection levels and with all terrain
capability. ST Kinetics will draw on its lessons and experience with the
Bronco, whose operational status with the Singapore Armed Forces coupled
with the number of variants fielded, makes ST Kinetics a credible and
highly qualified candidate.
ST Kinetics is approaching the Finnish concept study with the readiness to
embark on innovative and in-depth component or subsystem-level proofs of
concept which will be required in the course of the development. One
example is the Active Articulated Vehicle (AAV) concept, which allows
articulated platforms to couple and decouple quickly to form two separate
and smaller driven vehicles, each operating independently from the other.
The concept offers a “plug and play” convenience, allowing the
swapping of abilities even while the vehicle is in operation. The AAV
features prominently as part of ST Kinetics’ proposal, and offers a
technology that is ready and working, and can be easily integrated or
adapted for requirements in the near future.

Finnish inputs
Apart from a revolutionary design approach to meet user requirements, ST
Kinetics has set up partnerships with reputable and established Finnish
companies to explore the inclusion of Finnish components and more
importantly, to leverage their experience with the local terrain and
operational requirements.
ST Kinetics is the land systems arm of Singapore Technologies Engineering
(ST Engineering). It provides design and engineering services for both
commercial and military vehicles and related products, ranging from
manufacturing, upgrading, repair and maintenance to complete life cycle
management. It also provides component and subsystem design and
development, and laboratory and industrial test services.
Bronco seeks first export orders
Christopher F Foss
The Singapore Technologies Kinetics (STK) Bronco All Terrain Tracked
Carrier (ATTC) has been fully operational with the Singapore Armed Forces
for several years. So far more than 600 have been ordered with production
still underway. Bronco has already undertaken extensive trials in Finland
and more recently in France as both countries have a requirement for a
vehicle of this type. Also competing for both of these requirements is the
BAE Systems Hägglunds BvS 10, which is in service with the Netherlands
and UK Royal Marines and has also undergone extensive trials in France,
including the Alps.
The French Army programme is called the Véhicule Haute Mobilité (VHM)
with a total requirement, funding permitting, of up to 400 units. Both
contractors have submitted their bids to France. A decision is expected
early next year, with first order expected to be for about 50 to 60 units.
For the French market STK (Stand H10) would send the vehicles to French
company CEFA, which would fit specialised mission equipment. The vehicles
would then go to Thales, which would fit the electronic equipment.
At Eurosatory, a Bronco is being shown in French Army markings and fitted
out as an Artillery Forward Observation Officer (FOO) vehicle. Mounted
over the front unit is a remote controlled overhead weapon station
supplied by Thales and armed with a 12.7mm machine gun.
Singapore has already deployed a number of versions of the Bronco,
including ambulance, repair and recovery, load carrier, troop carrier and
fuel resupply vehicle. Other versions are under development, including one
carrying the STK 120mm SRAMS (Super Rapid Advanced Mortar System). Bronco
is already being expanded, including use as a robotic vehicle, as well as
being fitted with a new advanced patented coupling that links the front
and rear units. This unique feature allows the user to “plug and play
“ so that different units can be attached as required by the mission. In
addition, each unit can be transported slung under a tactical helicopter
and then rapidly linked at their final destination.
The units provide the crews with protection from small arms fire and shell
splinters, with higher levels of protection being an option. The
Caterpillar diesel engine meets EURO III requirements, with the total
available payload currently being 5,000kg.
The Bronco is also fully amphibious, being propelled in the water by its
tracks at a speed of 5km/h.
