Dunno, never tried TMO. Quick way to find out, fire up the mission editor, open \Data\Campaigns\Campaign\Jap_HarborTraffic.mis and see if it's in Luzon Straits. If it is, change spawn probability and frequency to make it show up, then go there in a career and look around. I haven't looked at ALL the campaign missions (stock 1.4 there are 653 of the little beasts) but consensus indicates that it only shows up in Luzon Straits, so anyone who never goes there would never see it.
