USCGC Seneca’s (WMEC 906) crew pulls into home port in Portsmouth, Virginia, Feb. 17, 2023, following a 24-day patrol in the Caribbean Sea. Seneca’s crew worked with Joint Interagency Task Force South and the U.S. Air Force to disrupt nearly 1,350 kilograms of narcotics from two law enforcement cases in the Caribbean Sea.

Not a big thing, but since we have been told USCGC Seneca was the prototype for the WMEC 270 SLEP,

“Coast Guard Cutter SENECA arrived in the summer of 2021 for the prototype Service Life Extension. Both SSDG and Emergency Generators replaced which included electrical upgrades to SSDG and emergency switchboards. SENECA was utilized as the prototype vessel for ISVS to the 270’ fleet that begins in 2022 with CGC HARRIET LANE.

and we have heard that the 76mm Mk75 gun and presumably the Mk92 Fire Control System are being removed during the SLEP, I wondered if the gun and firecorntrol had been removed?

A recent photo (above) accompanying a Navy League Seapower Magazine report of the return to homeport of USCGC Seneca after 24 day Caribbean Patrol clearly shows both the Mk75 and the Mk92 in place.
