They have some larger ships (pictures posted in another thread) that act as mother ships.
The larger ships were commandeered in the past.
I couldn't find any larger ship photographs although I tried.Maybe I need better search terms.
What many may have missed in this thread is the fact that "Private Security Firms" working in Iraq may get involved. We might see Blackwater teams on some ships, paid by Lloyds of London.
I have a feeling that if that is the case, we are about to see a fair collection of dead pirates in the future, and the larger pirate ships holed and sunk using shoulder launched anti-tank missiles.
That is a job I would apply for ;-)
