Max Damage on Bows?

Regarding the amount of CPs and $s invested into that ability, it doesn't strike me as particularly game-breaking. Considering that the same character dishes out 2d+3 swing damage without any advantages and a $40 axe, thus cleaving heavy plate in twain…

Of course there is no problem, but bows have the advantage of range, and a skilled enough archer could start shooting when enemies are at 200y and shoot 20 arrows before they come close.

All muscle-powered weapons – not just melee weapons – are limited to damage for three times the ST listed in the weapon tables. For bows of all kinds, the ST on the table doesn't rate user ST (which is a separate rating) but minimum ST to pick up and shoot a bow of that design without a penalty. See p. B270 for more. Just looking at the bows on pp. B275-276, then:

Short Bow or Crossbow (any kind): Min. ST 7, Max. ST 21. A bow can be designed to match user ST for ST 7-21; the user needs this much ST to operate the bow. The user has a skill penalty if his ST is 6 or less, regardless of the bow, because it's too bulky and heavy for him before he so much as draws the thing (which he might still be able to do with extra effort).

Regular or Composite Bow: Min. ST 10, Max. ST 30. A bow can be designed to match user ST for ST 10-30; the user needs this much ST to operate the bow. The user has a skill penalty if his ST is 9 or less, regardless of the bow, because it's too bulky and heavy for him before he so much as draws the thing (which he might still be able to do with extra effort).

Longbow: Min. ST 11, Max. ST 33. A bow can be designed to match user ST for ST 11-33; the user needs this much ST to operate the bow. The user has a skill penalty if his ST is 10 or less, regardless of the bow, because it's too bulky and heavy for him before he so much as draws the thing (which he might still be able to do with extra effort).

The same rule is why throwing knives and shuriken can't be as deadly as guns. They list ST 5 for the most part, which means that ST 16+ users are treated as if they had ST 15.

That said . . .

Agreed. Especially since this is true at later TLs even without much training. The latest, greatest rounds for reloadable RPG launchers and other LAWs do more damage per shot, with a greater rate of fire, than the lightest battery mortars and howitzers. What light artillery customarily gets you is sustainable fire and a wider range of ammunition options.

A 27" Scorpion (LT 82) does 3d imp with an average of 10.5 damage. The scorpion has a much less impressive rate of fire.

Am I missing something here? Can bows be built this strong?

What you are seeing is a result of GURPS' cinematic damage chart. According to the assumptions of the system ST 20 should do about twice the damage of ST 10, but actually it does about four times damage. Guns and artillery have their damage calculated differently, so a strong bow (cinematic scale) can do more damage than a powerful handgun or ballista (realistic scale). Realistically damage from a bow that an exceptional human being can draw caps around 1d+2 to 1d+3. Search the forums for various solutions: one would be to double HP and firearms damage and create a new damage chart where ST 10 = 1d thrust, 1d+2 swing; ST 20 = 2d thrust, 3d swing.
