Maybe its just me but I don't think 2 Knox class FF's and 4 O.H. Perrys are such a big threat. Yes, the harpoons maybe. Thats not much of a navy. And the Perrys only can carrie 4 harpoons X 4 ships is 16 missiles, and if you want to count the 2 cells on each of the Knox class only brings the total to 20 of the 53 missiles. I think the barak missile system can handle that. With the experience Israel has in air to air combat, and tank to tank. They should be ok. Just a opinion.
