The Army has long attacked forces at sea. Why should land-based fires be wrong simply because they have greater range?
The Army is aiming at China's fleet with its effort to create a joint fires network:
Project Convergence is aimed at rapidly accelerating the Army’s ability to find and take out targets by connecting people, vehicles and weapons through a massive, interconnected sensing and shooting kill web.
Which is fine.
The Air Force may complain but the Navy wants all the help it can get. The Army is creating a new and useful capability for INDOPACOM operations.
But the Army's core competency is large-scale ground combat. The Army needs to think about how it will take aim at China once control of the seas is established. The tyranny of the shores is absolute, as I discussed in Military Review.
Think about what comes after controlling the seas.
