Actually information on the operational readiness and how
well-equiped our RSN ships are, enemies need not tap from our SAF
personnel. They can get from their own citizens. Do you know
operational ships or rsn contract out ship husbandry contracts to
outsider contractors and most or 95% workers at least are
foreigners, if one or two are spies, they will get lotsa info
liao.
regarding the challenger sub, dismantling of eqiupment will not be
done by rsn personnel but by ST personnel and with the ST Marine
workers, be it bangla, indians, chinese etc.. they go onboard to do
servicing, engine or whatsoever, they will get valuable intel
liao.
So, look how well-protected are saf in intel.
