Griffin it up

ARABIAN GULF (Nov. 05, 2021) The Cyclone-class coastal patrol ship USS Firebolt (PC 10) fires a Griffin missile during a test and proficiency fire in the Arabian Gulf, Nov. 5, 2021. Firebolt, assigned to Commander, Task Force (CTF) 55, is supporting maritime security operations and theatre security cooperation efforts in the U.S. 5th Fleet area of operations.

Technically the BGM-176B Griffin B, or the Sea Griffin, is the navalized ground-launched version of Raytheon’s low-cost (compared to more advanced missiles) 34-pound bunker/tank buster that was lighter than the Hellfire used by the Army was originally designed for use from helicopters, UAVs and Marine KC-130s/USAF MC-130s.

Originally pitched as an add-on for the LCS to enable it to zap especially rowdy pirates and asymmetric fast boat threats, the 13-pound warhead would only really be effective against a larger ship in the case of bridge shots and needs an operator with a semi-active laser to paint a target. With that, the Navy opted for a modified Longbow Hellfire– which can use the ship’s radar and be used against multiple targets at once– for the LCS, along with the Naval Strike Missile for heavy work.

However, adopted as the MK-60 Patrol Coastal Griffin Missile System (GMS), the chunky Griffin B has been getting it done on the 170-foot Cyclones, in twin four-cell topside mounts, since 2013. This gives each of these short boys eight decently powerful close-in (3-5nm) missiles, coupled with the ability to use the ship’s mast-mounted Bright Star EO/IR camera for targeting, which gives them a solid stand-off capability against Iranian Boghammars and similar threats. 

Personally, I’d like to see it installed on the Coast Guard’s very similar 158-foot Sentinel-class Fast Response Cutters, at least for the six of the class intended to operate forward deployed with PATFORSWA in the Persian Gulf under CENTCOM. They could also likely be of use on the USCG’s increasingly WestPac units of the same class

New Sentinels for the Persian Gulf

This weekend Coast Guard Sector Key West waved goodbye to the newly delivered Sentinel (Webber)-class Fast Response Cutters USCGC Robert Goldman (WPC 1142) and USCGC Charles Moulthrope (WPC 1141). The 154-foot cutters were recently delivered by Bollinger and were purpose-built for their new mission.

The two cutters are headed to the Arabian Gulf in support of Coast Guard Patrol Forces Southwest Asia in Bahrain. They are equipped with the CG-HALLTS system, a hailer that has laser and LRAD capabilities, as well as a special S-band radar with full-time 360-degree coverage, and other goodies. 

If you note, they four have Long Range Acoustic Devices (LRADs) on the O-1 deck as well as four Sierra Nevada Modi RPS-42 S-Band pulse doppler radar arrays on their masts. The cutters’ Mk38s are also painted FDE.

Note the 270-foot Famous-class medium endurance cutter USCGC Mohawk (WMEC-913) in the background– the last class in American service with a MK 75 OTO.

As noted by the Coast Guard:

PATFORSWA works with Naval Forces Central Command to conduct maritime operations forwarding U.S. interests. These efforts are to deter and counter disruptive countries, defeat violent extremism, and strengthen partner nations’ maritime capabilities to secure the maritime environment in the Central Command area of responsibility.

Under Naval control, PATFORSWA first deployed to the region in 2002 in support of Operation Iraqi Freedom with six Reagan-era 110-foot Island-class patrol boats and has been extensively involved with Iranian Revolutionary Guard forces there ever since, augmenting the Navy’s 170-foot Cyclone-class PCs.

Much more capable craft than the aging 110s, the FRCs are expected to replace the latter on a one-for-one basis.
