Subject: Re: About Iran’s Navy “At the Bottom of the Sea”
Except for a brief showing of the flag in the strait by two Arleigh Burkes, the US Fleet hasn’t ventured into the Persian Gulf- because of that speedboat with the AK toting Iranian Guard in the back that you mentioned.

Just looked up the info on the Persian Gulf, and it does strike me as being remarkably shallow:

Average depth 50 m (160 ft)
Max. depth 90 m (300 ft)

Still plenty deep enough for the Navy though I'd imagine. And not that different than the depth of the Great Lakes:

Lake Erie	        Lake Huron	Lake Michigan	Lake Ontario	Lake Superior
Average depth[13]	19 m (62 ft)	59 m (195 ft)	85 m (279 ft)	86 m (283 ft)	147 m (483 ft)
Maximum depth[15]	64 m (210 ft)	228 m (748 ft)	282 m (925 ft)	245 m (804 ft)	406 m (1,333 ft)
