It's really 2 carrier battle groups and 2 amphibious warfare battle groups, double the normal complement. The purpose is open to speculation: Most likely to add weight to diplomacy and shore up the Gulf States. Or for those of a more Machiavellian bent, to rope-a-dope Iran and shore up oil prices. The last time the Iranian navy took on the U.S. Navy, Iran lost 1/3 of its surface fleet in an afternoon. A naval attack would open the way for an aerial attack on Iranian WMD sities. For confirmation, watch for air assets to move to Incirlik and Al Udied.
Don't know about Turkey, but Qatar is still loaded from the Naval Interdict Ops held a coupla weeks ago.
Are all the ducks in a row yet?
Very interesting! Stay well armed and safe.............FRegards
