We’ve gone from just supplying Javelin missiles to all of NATO pumping in everything under the sun.
Outside of Javelins, old Stingers, and artillery shells, we’ve barely scratched our inventory. Virtually nothing that would be of much value in a dustup with China.
Meeting Ukie needs for artillery shells is really the issue, this summer. But a shift toward the GLSDB’s could help with that: Russian artillery is useless if all THEIR shell stocks within 80 miles of the front get smacked. The US has said GLSDB’s are some months away, however, that may be a ruse.
If we simply sent the 96 HIMARS scheduled for delivery to US stocks in 2023 to Ukraine, that’d have quite an effect. (And we’d still have over 400 left.)
