Had an interesting discussion about why the National Security Cutter retained the Phalanx Close In Weapon System (CIWS) while the very similar weapons suite on the Freedom class Littoral Combat Ship used the Rolling Airframe Missile (RAM) system instead.

My friend contended that, while the Phalanx is very maintenance intensive, the launcher for the RAM is virtually maintenance free, which would benefit the relatively small crew. He also noted that the current models have an excellent anti-surface capability and longer range than the Phalanx.
This got me to thinking. I won’t make a recommendation, but will discuss alternatives that might be considered. I’ll talk about who is using the RAM and how, and discuss how the Coast Guard might use it, and its advantages and disadvantages as a possible replacement for the Phalanx and possibly even the 57 mm. But before we get to that, as we are always told, you have to start with the mission.
