The number of ATACMS in American stockpiles is fixed, awaiting replacement with the next generation, longer-range Precision Strike Missile, called the Prism, for PrSM, which is expected to enter service by the end of this year, officials said. Lockheed Martin still manufactures 500 ATACMS each year, but all of that production is destined for sale to other countries.

How is the stockpile fixed when i also says they making 500 each year lol? Are American's using them somewhere? Did Canada and Mexico get rowdy lol? 190 mile range isn't exactly something they need to stock pile in their own backyard as I would argue they would want something with a greater distance to hit enemies approach the US long before the 190 miles range. I could easily give up 1 year's worth supply. 

See the bit in bold.
