Below is a Coast Guard news release. It is otherwise a pretty typical patrol report, but I wanted to call your attention to one paragraph,
“Of note, this patrol marked a significant historical event for the Coast Guard’s Famous-class medium endurance cutter fleet. Mohawk was the last in its class to fire the onboard Mk 75 mm gun weapon system. The largest caliber weapon in the Coast Guard inventory, it has been utilized by Famous-class cutters like Mohawk since they were first commissioned in the 1980’s. Now, large caliber weapon systems onboard Famous-class cutters are being modernized for a service life extension program.”
Does this really mean the Coast Guard is stopping support for all 76mm gun and Mk92 fire control systems even though only six WMEC270s are expected to receive the full life extension program? USCGC Harriet Lane which went through a partial SLEP, has also swapped out her 76mm for a 25mm Mk38, but that still leaves six WMEC270s that will not go through the service life extension program. Will they also lose their 76mm guns?
The 25mm Mk38 is a poor substitute for the 76mm gun that is upgradable and still in service with about 40 countries.
Coast Guard Cutter Mohawk returns home from 62-day migrant interdiction operations patrol
KEY WEST, Fla. — The crew of Coast Guard Cutter Mohawk (WMEC 913) returned to their homeport of Key West, Oct. 11, following a 62-day migrant interdiction operations patrol in the Florida Straits.
Mohawk’s crew deployed in support of Homeland Security Task Force – Southeast (HSTF-SE) and Operation Vigilant Sentry (OVS) while underway in the Seventh Coast Guard District’s area of responsibility. While on patrol, crew members worked alongside additional Coast Guard units and partner agency crews to detect, deter and intercept unsafe and illegal migrant ventures bound for the United States.
While at sea, Mohawk crew members interdicted and rescued 41 migrants from unseaworthy vessels. Of these, Mohawk’s crew rescued 25 migrants aboard a single disabled vessel found taking on water in the Florida Straits on Aug. 20. Throughout the deployment, Mohawk cared for a total of 53 migrants, providing shelter, sustenance, hydration and medical care before conducting safe repatriation back to their country of origin.
On Oct. 3, Mohawk’s crew conducted a rescue of four personnel stranded on the remote island of Cay Sal, Bahamas after their seaplane was disabled. Mohawk coordinated with a U.S. Navy P-8 Poseidon airplane and a Coast Guard Air Station Miami HC-144 Ocean Sentry airplane to vector in Mohawk’s small boat crew for the rescue.
Most recently, the crew of Mohawk extended their deployment in response to the approach of Hurricane Milton. Mohawk sortied alongside other Key West-based Coast Guard cutters to avoid potential storm damage and ensure response readiness after the hurricane. Mohawk’s crew also conducted a tow of the Isaac Mayo during the sortie for several days of rough seas as the cutter was disabled due to scheduled maintenance.
Of note, this patrol marked a significant historical event for the Coast Guard’s Famous-class medium endurance cutter fleet. Mohawk was the last in its class to fire the onboard Mk 75 mm gun weapon system. The largest caliber weapon in the Coast Guard inventory, it has been utilized by Famous-class cutters like Mohawk since they were first commissioned in the 1980’s. Now, large caliber weapon systems onboard Famous-class cutters are being modernized for a service life extension program.
To successfully conduct the migrant interdiction mission, Mohawk partnered with U.S. Customs and Border Protection – Air and Marine Operations air and boat crews as well as additional Coast Guard units to include Coast Guard Cutters Charles Sexton (WPC 1108), Raymond Evans (WPC 1110), Isaac Mayo (WPC 1112), Maple (WLB 297), Coast Guard Station Key West, Coast Guard Sector Key West and Coast Guard Air Station Miami.
“Outstanding work by the Mohawk crew. I am very proud of our ability to secure our nation’s maritime borders while maintaining the safety of life at sea,” said Cmdr. David Ratner, commanding officer of Mohawk. “We understand the importance of deterring unlawful and dangerous maritime migration attempts on often overloaded and unseaworthy vessels. One such vessel with 25 migrants on board was disabled with insufficient fuel to make it to land and was taking on water.”
Mohawk is a 270-foot, Famous-class medium endurance cutter with a crew of 100. The cutter’s primary missions are counter-drug and migrant interdiction operations, enforcement of federal fishery laws as well as search and rescue in support of Coast Guard operations throughout the Western Hemisphere. Mohawk falls under the command of U.S. Coast Guard Atlantic Area, which is based in Portsmouth, Virginia. U.S. Coast Guard Atlantic Area oversees all Coast Guard operations east of the Rocky Mountains to the Arabian Gulf.

thanks Chuck, interesting.
We had a joint professional society (SNAME (Society of Naval Architects and Marine Engineers)/ASNE (American Society of Naval Engineers)) tour of the Coast Guard Yard last spring. My memory is that they mentioned that they were providing support for all 76mm gun systems including those on ex-USN FFG-7 class. It’s still listed under the capabilities for the Ordnance Shop (www.dcms.uscg.mil/Portals/10/CG-4/documents/SFLC/YardCapabilities.pdf).
I also visited the yard and they were still doing support for the weapon. That is part of the reason I was surprised to see this claim in the press release.
Given all 12 WHEC378s are still out there in service with 76mm Mk75s, I am sure they will need to continued support.
This may be another response to the Coast Guard’s personnel shortage.
I may be really the fire control system rather than the gun that is unsupportable. One of the new multifunction radars like those on the NSC and OPC could actually function as a replacement fire control system as could a Mk20 electro-optical system.
