Level 5 is the max level for special weapons. Not 10 or 15, like airplanes.

It is sometimes worth upgrading special weapons. All special weapons get a little boost in damage (Minus ECM and ESM), the range also goes up for some. The damage radius goes up for bombs, and the reload speed also increases.

If you are thinking of upgrading weapons, be aware of the prices.

Upgrading to level 2 usually costs around 40,000-65,000

Level 3 is mostly in the 100,000 range

Level 4 is in the 200,000-400,000 range

The max upgrade level 5 can cost around 700,000-900,000

Hope this helped!
