Unmanned systems have become a ubiquitous threat and in many places the Coast Guard is the only military. Consequently it seems the Coast Guard needs a counter to this threat down to at least the Webber class WPCs. Multipurpose systems that would also be useful against low flying aircraft and surface vessels in addition to UAS would also be useful.
“A new and not immediately recognizable launcher has emerged on the U.S. Navy’s Arleigh Burke class destroyer USS Carl M. Levin. Last year, launchers for Coyote counter-drone interceptors appeared in the same general location on two other Burkes, the USS Bainbridge and the USS Winston S. Churchill. The Navy is currently known to be exploring several other options for integrating lower-cost anti-drone interceptors on various warships to bolster their defenses against this ever-growing threat. The new launcher could also be for deploying other kinds of munitions, drones, and/or decoys.
The Navy has been successfully countering this threat, but has been forced to use very expensive systems to counter very inexpensive, potentially numerous threats. Apparently they have been seeking lower cost counters. As a result some new hardware has been showing up on Navy destroyers.
Hopefully, the Coast Guard is following the progress of these lower cost options with an eye toward incorporating them into the Coast Guard.
The good news for the Coast Guard is that the systems appear to be relatively light and do not require extensive deck penetration.
These were believed to be for Coyote or Hellfire/JASM. Hellfire and JASM are pretty well known but Coyote is relatively new so I have selected a couple of short videos to explain what it is.
What does the Coast Guard have now?
The 57mm Mk110 particularly with ALaMO is probably a good self-defense counter to UAS. Unfortunately, it appears the more sophisticated MAD-FIRES round never became operational.
The Phalanx is certainly capable for self defense against a small number of UAS but it can use all the onboard ammunition in 20 to 30 seconds. Navy is replacing Phalanx on its destroyers with either RAM or SeaRAM Rolling Airframe Missiles. Hopefully SeaRAM will replace Phalanx on NSCs and be added to the OPCs.
The real problem with both of these systems is that they will only be on NSCs and only the 57mm on the OPCs. These large ships will generally be either in port or on patrol far from their home ports. They are not generally available for short duration force protection missions or for response to near term intelligence. We need a counter that can respond rapidly as threats develop.
The WPCs, WPBs, and to a lesser extent buoy tenders are the likely candidates to do force protection, respond to intelligence, or provide a movable cUAS platform, but the 25mm Mk 38s and .50 caliber machine guns are unlikely to successful against UAS and they can cause collateral damage if not used carefully. Better lead computing sights could be provided for the .50 caliber machine guns. Replacing the 25mm guns with 30mm guns capable of firing air burst projectiles would be a major improvement.
I would really like to see Hellfire or APKWS added to WPCs, WPBs, and yes, even buoy tenders.
