HSY-55-class gunboat

The HSY-55-class gunboat is a class of naval vessel designed by the Hellenic Navy and built by Hellenic Shipyards (HSY). This class of ship uses the modular concept so that weapons and sensors can be changed as required. These vessels are similar in appearance to Osprey 55-class gunboat. The first pair was ordered on 20 February 1990, but completion was delayed by the shipyard's financial problems. Pyrpolitis (P57) was launched on 16 September 1992, and Polemistis (P61) on 21 June 1993. Each ship can carry 25 fully equipped troops. Alternative guns and Harpoon SSM can be fitted as required.

gollark: - it funds the BBC, but you have to pay it if you watch *any* live TV, or watch BBC content online- it's per property, not per person, so if you have a license, and go somewhere without a license, and watch TV on some of your stuff, you are breaking the law (unless your thing is running entirely on battery power and not mains-connected?)- it costs about twice as much as online subscription service things- there are still black and white licenses which cost a third of the priceBut the enforcement of it is even weirder than that:- there are "TV detector vans". The BBC refuses to explain how they actually work in much detail. With modern TVs I don't think this is actually possible, and they probably can't detect iPlayer use, unless you're stupid enough to sign up with your postcode (they started requiring accounts some years ago).- enforcement is apparently done by some organization with almost no actual legal power (they can visit you and complain, but not *do* anything without a search warrant, which is hard to get)- so they make up for it by sending threatening and misleading letters to try and get people to pay money
gollark: Hold on, I wrote a summary ages ago.
gollark: TV licenses aren't EXACTLY that, they're weirder.
gollark: The UK does free terrestrial TV, I don't think satellite is much of a thing here.
gollark: They were initially meant to be reducing the number of people going, in the UK.
