This requires more space however, so the boats are growing in size and displacement despite carrying fewer missiles. The most noticeable stealt...

They are different; American and French designs will carry more missiles, wile the British design as the most obvious emphasis on new stealth technologies. But the bigger takeaway is that they are also in ma...
