Getting some live-fire Griffin time in

Five TF55-based Cyclone-class coastal patrol ships —USS Tempest (PC 2), USS Squall (PC 7), USS Chinook (PC 9), USS Firebolt (PC 10) and USS Thunderbolt (PC 12)— recently had the chance to sling Griffin SSMs at moving target sleds to demonstrate their ability to hit surface targets, like small boats.

The tests came late last month, around the time of increased Iranian challenges in international waters from Revolutionary Guard small craft in the PG.

The MK 60 Griffin Missile System uses a four-cell box launcher about the size of a Barcalounger, with one each mounted port and starboard on the 179-foot PC, giving them 8 modified Hellfire missiles at hand to regulate small craft–and I would bet low/slow-flying aircraft as well.

The system began fielding in 2015 and uses a Battle Management System (BMS) based on a ruggedized “Toughbook” laptop is operated from the bridge drawing from target imagery from the ship’s mast-mounted Bright Star EO/IR camera. Range is listed at 3nm, but is likely a good bit longer.

While the 13-pound warhead isn’t likely to sink a frigate, it and the kinetic energy of the missile itself is probably good enough to scratch anything less than 100-footer while a salvo of four (as they can be ripple fired to the same illuminated target) could ruin the day of a corvette-sized warship if needed. Good news is they can’t be chaffed or EW’d away due to the IR nature of their warhead seeker. Bad news is the target has to be lit up the whole time by Bright Star which limits a shoot-and-scoot engagement.
