US nuclear sub and destroyer enter Red Sea
Two ships of the US Navy, the nuclear submarine USS Annapolis and the destroyer USS Momsen have passed through the Suez Canal into the Red Sea. Although their destination is confidential, they are now getting dangerously close to the Persian Gulf.
'Dangerously'? I think they know their way around...
The shipsÂ’ passage was a major operation for the Suez administration as due to safety reasons they had to close off the canal to all other traffic and even shut down the bridge, disrupting the link between the banks for some four hours. The traffic on the roadways alongside the canal was also restricted, Interfax news agency reports.

There are no reports regarding the destination of the vessels, but the news come amid the ongoing crisis in the relationship between the US and Iran. There is mounting speculation that the Annapolis and the Momsen are heading to the Persian Gulf to reinforce the US naval forces already present in the region.
They might be going for anti-piracy duty off Somalia. Or a flag-showing exercise in Ruritania...
Currently the US has two aircraft carrier groups in the region headed by USS Abraham Lincoln and USS Carl Vinson. It is expected that another aircraft carrier, USS Enterprise, will join the strike force in March.
