What would be the ramifications of terrorists attacking the Panama canal and badly damaging the loch systems for an extended period. The Canal is vital for linking US shipping and trade (and other nations of course). How could such an attack be carried out and how would the US react?
It wouldn't be that hard to do. The designers of Panama Canal were worried about the possibility of an out of control ship ramming the gate on the top Pacific side lock on the way down. They designed a few systems to try to mitigate the danger such as arresting gear chains and a series of pylons that could be slammed into specially designed slots, but all those systems have since been removed and were never used when in service. The only system still in place are the double doors for the locks, the designers thought it unlikely a ship could ram through both doors at once. If the top gate were to fail there would be no way to stop Lake Gatun from rushing out and with it the water vital to the operation of the canal. The locks themselves aren't the weak point, it's the lake.
I thought Asia-Europe shipping normally went via the Suez?Every one of those ships would wind up with at least two extra weeks, most with more than three, sailing time, one way on the Asia-Europe and around two weeks on the Asia-New York transit.
Taking out the Canal is a LOT harder than you might think, although it could be done. The "best" way would be with a cargo ship rigged to detonate while in the lochs.
Nice quote from wikipedia.
Although I agree that a few of the safetymeasures have been deleted, it's still going to be very hard to get 4 sets of doors to go bust, as you'd need not only to bust the 2 doors on one side of a lock, but on both sides in order to be able to attempt to drain the lake.
So I agree with the previous poster that it'd be quite hard to damage the Canal for more then a few weeks.
AFAIK even if the lake is drained completely, I'd refill in approx one year.
Furthermore, AFAIK there's an enormous overcapacity in shipping at the moment due to the economic situation worldwide. There are shitloads of ships just anchored outside major harbours such as Singapore, Rotterdam and such. Probably a lot more then the 12% (why not 13% or 11% ) a previous poster mentioned... If anything transport is too cheap compared to the resources it costs and has been so for decades, this would remedy that.

The global economic impact would be incredible. Over 14,000 vessels, most of them cargo ships of one stripe or another, use the Canal every year. Every one of those ships would wind up with at least two extra weeks, most with more than three, sailing time, one way on the Asia-Europe and around two weeks on the Asia-New York transit. It would be like sinking 12% of the world's merchant fleet at a stroke.
In response to the OP :
That's not what terrorism is all about. Terrorism is a staged drama for a civilian audience.
The bad guys on 9/11 didn't crash those jets into a military target - a docked carrier at Norfolk naval base for example.
Blowing up or blocking the Panama Canal is something that no terrorist group would ever do IMHO.
