So what would be your tips on how to use (or not to use) the SST's?
The first SST, the type Yu (10 of them), have a capacity of 40 and a range of 75 hexes, using 5 fuel a day. Their only gun is a 37mm AA.
Put in charge a timid naval officer. Set the task force to safe, low routing levels, cruise speed.
Never run out of fuel with these guys. They will die by either to air or enemy forces very quickly.
Don't disband them to port except where absolutely safe from strikes.
Since they are such fuel hogs, the best place to use them is in the SRA. The Central Pacific isn't so great because of their thirst. A secondary decent place is the Japanese Islands area or even the Yellow Sea if you have imbalance in Chinese supply late game. Perhaps running supply from Hokkiado to Kuriles/Marcus depending up on the game...
You can have them arrive in 43, but don't force their use. Save them for late game when you need them.
They work best running supply from bypassed SRA production centers...away from the deathstar, heavy aerial ASW search routes.
At only 40 units of capacity think about the impact those supplies will have versus the risk of running a 20+ VP gift to them.
Currently I am using them from Miri to China. They can make several runs a month, and China needs all the supplies I can get her, while the risk of blundering into the deathstar is very low currently.
