A couple of stories brought to my attention by readers,
Bangladesh Navy , BNS Bijoy, armed with 1 x H/PJ-26 76 mm main gun, 4 × C-704 AShM, and 2 × Oerlikon 20 mm auto cannons
First a look at how Bangladesh has been using a couple of second hand British built Castle class OPVs. (Bangladesh now has two former USCG WHECs, so its good to see they take care of their ships. Thanks to Sven for bringing this to my attention.)
USV sighted in San Diego
Second, a report of a new unmanned surface vessel operating in San Diego. Looks like a test mule rather than a final product. (Thanks to CaptnMike for sending me the link.)

The Castles are lovely ships. The RN should have bought more of them!
Chinook capable flight deck too……..
Wow that is quite a picture. Not sure the USN would have considered that as an option
