Hozer is dead on. Surface combatants are not like a tank or even a LPD. The LCS will be called upon to do independent ops in combat zones and yet we only give it last ditch defense weapons and a helo deck. Why don't you ask the Israelis how well their similarly equipped Saar V corvette fared off Lebanon in 2006. Gators serve a purpose but it is not as a regular combatant.
Every combatant ship in the Navy should be a self-sufficient weapon system, not reliant on other ships to protect it. Because no matter what is intended they will operate alone and unafraid, intentions or not. A few dinky little UAV's carrying tiny little rockets aren't going to do anything but show the 9 small speedboats with ASCM's heading for the ship, outside the range of its weapon systems, and the LCS ain't going to be able to do anything watch and wait for the 30-odd missiles heading for it. At that point, just bend over and kiss your ass goodbye.
I'm sure you are privy to info I don't have on the incident, but publicly, Israel alleged the Hanit's air defense systems were not turned on and fully ready due to friendly aircraft and no expectation of a ASCM threat. There was apparently also a communications breakdown between intel and the fleet, as the intel on Hezbollah possession of ASCMs did not translate to a warning to the fleet, which would have caused them to move out of visual range and increase threat warning/weapons posture.
If this is in fact true, even an AEGIS ship wouldn't have done better in that situation. Seems to me bad shipboard intel was the culprit, not the ship itself.
Frankly, I see no reason a stealthy platform like LCS not operating in visual range of the coastline would be an easy target for coastal ASCMs, or even FAC/FIAC boats.
The 9 speedboat scenario is too simplistic as well. What is ROE? Can the LCS simply turn and haul ass? It goes 40+ knots with blue water capability, it can ditch FIAC boats, and FAC boats would have a difficult time tracking it out in blue water.
And why would a lone LCS operate where we expect a high ASCM/ASUW torpedo threat? Do we send unescorted F/A-18 strikers into a highly sophisticated IADS?
