A SM1 light tank replacement is my personal
guess. My opinion is that a heavy / light
tank mix will give SAF operational flexibilty for
different scenarios , although light tanks do not have
a very successful operational history in warfare. But with
new technologies ( eg APS, sensors, hybrid electric
drive etc ) , light tanks can be viable for
certain scenarios. Also, trend is towards lighter AFVs
as proposed in USA.
As can be seen, ST & MINDEF will develop own equipment
for SAF as far as possible if off the shelf not
suitable. It cud be a modified / upgraded Bionix type chassis
with off the shelf turret or cud be off the shelf
chassis with locally developed turret ......etc
Currently there is no new generation type of light tank in
development that I know of which incorporates most or all
the new / future technologies. There are also only a
handful of off the shelf light tank options available now
which incorporate some of these new/future technologies.
