My contribution. The helos are civilian registered belonging to my private security company that I rarely write anything about because I'm busy with Atlantia...
She's armed with a BK-27 forward in an Oto Melara Marlin. Moving back there are assorted machine guns M3Ms are shown but they could equally be GAU-19s, M134s GPMGs etc. Moving further back there is a pedestal launcher for a variety of munitions, Hellfire is shown but seeing as Atlantia operates SPIKE they'd most likely be used. Again up to the end use what they fit on them. Below the launcher is the helicopter hangar which is large enough to hold two Huey sized helicopters with ample room to complete maintenance without having to move one outside. aft of that is the helipad which is strong enough to take anything up-to an S-92 sized helicopter. Under the helipad are a pair of remote weapon stations able to be fitted with the same weapons that are crew served further forward. Finally at the stern there is space for a number of small boats, I've got two quite substantial RHIBs shown, recovery and launching is done up a ramp whilst semi submerged.
XPV-A has a crew of around 35 plus 20 for the air assets and two 8 man SOF teams. There is room on board for a further 12 personnel for medium duration visits as well as detention facilities, max speed of around 20 knots and endurance for around 60 days.
