Ok Still not the entire swedish navy. And yeah you could probably destroy those easy but not before they get their missiles in the air, which means both sides are destroyed. How many SSM do you think the rest of the world can scrounge up? How many ASM? Because it basically comes down to that, do they run out of missles before you run out of ships, not likely.

Each with enough rb-15s to cause consierable damage to any target even if they get blown up directly afterwards.
Phalanx CIWS.
Every single US Navy ship has at least one of these.

And:
SeaRAM
