Well, this time last year- and even today... According to open sources we have six warships sitting there... I know you are good at looking stuff up, you could do a quick search and find news articles from recent years about the Somali pirates and our Navy's interactions.
Flash, whether you think its important or not pirate activity in that part of the world is something that we send assets to cover. Sometimes that means parking a DDG or 3 (yes, I've actually seen three sitting right off the shore there- with several other ships steaming in circles a little farther out) off the coast to encourage the release of hostages and vessels. I really don't forsee this changing in the near future.
Open source, huh? Well, all I can say is live by the gouge, die by the gouge. I know exactly how many ships we have there and if you have access to SIPR it would be very easy for you to know too.
Like I have said before there are usually several allied ships in the area, and supposedly a Russian one is coming soon, that keep an eye on the pirates. This includes the Brits, Danish, French and others, so you may have seen those ships. And occasionally we will 'surge' to a few more than usual and others will be transiting through there. But with all of our other numerous commitments, we do not have the ships to maintain a large standing force off the Somali coast. Believe me when I say this, Somali pirates are pretty damn low on our priority lists usually.
