I don’t see the point.
Poor range and slow reaction time to deliver over-the horizon anti-ship missiles. You want the missiles off as soon as you can after getting a contact.
Vulnerable to interception.
The only advantage I can see is the ability to use terrain to hide in until they pop up to fire.
That would work if there is terrain.
Harpoon is a pretty big weapon. I would think they would want something smaller like a Penguin.
Me neither. That's why the Navy spent a gazillion dollars on Seahawk gunship upgrades - this is a mission that is already being done.
I’d wager the driving factor here is the currently nonexistent offensive capabilities of the LCS class.
