Looking at Barb/Archerfish, it's 14/15. Its SA is stronger than Barbs and it has one extra torp at range 2. Just Depends how you compare it to Archerfish two SAs. Torpedo Swarm is arguably the strongest of the lot. Archerfish has two but slightly lesser.
Probably 14?

I do seem to remember a discussion around this way back when. With hindsight and everything that's come along since Barb should have got the extra torp and been 13. If that reasoning was continued now, others including Tang would be penalised too. Torpedo swarm is stronger as it's not OPG.
But regardless, 14 pts is right as is for Tang.

TORPEDO SWARM: Whenever this unit makes a Torpedo attack, it may make an additional 1-die Torpedo attack against all other enemy Ships in the same sector.
USS Tang is credited with the largest number of sunken japanese ships, and greatest tonnage sunk. As well as the most successful patrol in tonnage sunk. This, her 3rd patrol saw her make 2 attacks on merchant ships in quick succession. It was only when Japanese records were examined post war that it was realised the Tang had sunk 4 ships from 6 torpedoes.
