Lockheed Martin has opened a second production line to make two of the Pentagon’s most in-demand weapons: the LRASM anti-ship cruise missile and the JASSM-ER air-to-surface variant. Wargames have shown the utility of the missiles in countering a Chinese invasion of Taiwan. The problem is that the simulations also show that the stocks of AGM-158C LRASM and JASSM-ER from which it is adapted would be quickly expended in a conflict, putting pressure on the services to boost their modest inventories.
