NavyRecognition reports, “The State Department has made a determination approving a possible Foreign Military Sale to Qatar for Mk-V Fast Patrol Boats, equipment, training, and support. The estimated cost is $124.02 million.”
Based on the number of .50 calibers ordered, it appears that this will include four boats.
Looking back, in 2009 DefenseIndustryDaily reported the sale of ten of these craft to the Kuwaiti Navy under the Foreign Military Sales (FMS) Program for $61.6M. Saudi Arabia is also interested in these boats and is reportedly planning to buy 30 at an estimated $1.2B.
I don’t recognize the 27 mm reportedly included in the Qatar deal as a weapon in US service, but the Germans (Mauser, now Rheinmetall) do make a 27mm and this is the gun used on the Kuwati boats, and it appears to be gun used on the boats for Qatar.
The size of the boat seen on the stern ramp in the video is not clear.
These 90 foot boats is clearly optimized more for speed than our 87 footers. They also have a shorter range and with water jets, are probably less manuverable at the slow speeds often required for SAR.
