I can only see one situation when I might want to consider it.  Buy a carrier with two fighters (or use two of the starting fighters the US gets on their base) and pay one supply token to get that carrier onto the main map at the earliest moment.  I can’t see paying $2 to get anything else into the game early.  But getting $7 + $3 + $3 worth of stuff into the game quickly might be worth a look.  It could save a task force that just invaded New Georgia and took heavy losses in sea zone “I” but the ground units did OK.  Those extra two aircraft might make a big difference next turn if you need the ships to provide fire support to defend the counter attack next turn.

I may just have to look at that.  Turn 1 US takes Guadalcanal, Malaita and Santa Isabel.  Turn 2 US invades New Georgia from sea zone “I” pulling forces from Santa Isabel and Guadalcanal and resupplies Santa Isabel with stuff from Malaita if Japan doesn’t “counter invade” heavy in Santa Isabel from Choiseul.  If somehow the US ships lost many escorts in sea zone “I”, a rapid deployed carrier in “I” or “J” might keep the US navy afloat.

Speed kills.
