Hi Defcon, I would be sceptical of that range figure for the ESSM if I were you. The actual range is classified, but from the more reliable sources I have seen, the range is between 15-20kms, which would sound about right as the ESSM is considered a short range defence missile to fit in between the Phlanax/Ram and SM2/3 in the USN layered defence.Defcon 6 said:No, ESSM has a range of 55km and SeaWolf has a range of 10 km. Then again ESSM is 6 times heavier.
