As I have suggested several times, there is a place for this system in the Coast Guard, here, here, and here, as a weapon that would allow even small units like patrol boats and FRCs to quickly and accurately deal with a range of threats, while minimizing the risk of collateral damage inherent in the use of our current weapons, e.g. 7.62mm, .50 cal., 25mm.
These weapons are not exotic. tens of thousands are produced annually.
Interesting to see how simply the pulse repetition frequency code is set to match it to the laser designator.
(I would also argue that the Coast Guard needs to have available laser designators in order to allow us to specifically identify threats for DOD aircraft that might be called in to help the Coast Guard deal with a threat.)
The first place to mount APKWS is on the FRCs going to PATFORSWA.
It is probably possible to mount launchers on the Mk38 gun mount. There is also the four round FLETCHER launcher (see below) that can be fitted in place of a .50 cal.
