Many tanks from the Thailand Navy are left idle
in deports and are not being utilised due to budget constraints.
Some have their engines started once or twice a day to maintain
their usability. However, there are others left obsolete.
This has been the scenario since the 1997 economic crisis,
as tanks consume large amounts of fuel and are expensive to
maintain. A heavy tank like M60-A3 or M48-A5 consumes three
litres of diesel a kilometre. Smaller tanks use two litres of
diesel a kilometre.
Examples of tanks not used effectively include the T-85 APCs
from China and 106 American-made Stingray light tanks. Many
of these tanks are being used for mock army exercises. High
costs occur when it comes to the upgrading and the maintaining
of the tanks.
The Ordnance Department is now in the process of upgrading
25 British-made Scorpion amphibian tanks, for 12 million baht
each. These tanks are being equipped with a night vision system
to enable night combat, and their engines are being overhauled.
