U.S. missile-defense stocks are under mounting strain, the WSJ reports. CSIS estimates America has burned through half its prewar stocks of interceptors such as Patriot and THAAD and now has only 800 Patriot missiles left. Lockheed Martin delivered 620 PAC-3 MSE interceptors last year, up more than 20%. Russia, meanwhile, is estimated to produce more than 100 ballistic missiles and roughly the same number of cruise missiles each month, highlighting a widening production imbalance.
