Revealing Submarine Info: Gulf Crowded and ...
Consider the implications of these recent (and unrelated) news statements:“When we had submarines in the Gulf,” said Florida’s Chief of the Boat, Command Master Chief (SS) Harold Miller, “it’s a huge waterspace management issue to have multiple submarines in this area. If we had two of the [SSGNs] there, we could have launched more missiles and still not had the waterspace issue that we had.” source: Multimission-Capable Sub Readies for Full Operation
Add to the above Bubblehead's opinion: I will say that they are technically right when they say that "military experts opine that Iran has up to six Russian-built SSK or SSI Kilo-class diesel submarines prowling the Gulf." "Exactly three" could be included in "up to six", I suppose;
Who else's subs could be in the gulf? One thing is fairly certain -not Nigeria. Turkey, of course, would be around and the UK has also been working on blue colored subs for that type of environment. The Russians have had a few there, from time to time, also. And, there is this: Leading off the always lurking and deadly wolfpacks is Israel's fleet of Dolphin-class submarines, each carrying U.S.-supplied Harpoon cruise missiles - armed with nuclear warheads. source: Silent Nuclear Submarines Add to Iran Tensions. Again, if one beleves the writer has been careless with his source(s) as Bubblehead pointed out, there is little reason to believe Israel's boats are equipped with American-made Harpoon missiles modified to carry small nuclear warheads  . Except for the fact that Israel has proven it is not careless with its security.
Submarines are always silent and strange.
