USS Bronstein

The Bronstein-class frigates were United States Navy warships, originally laid down as ocean escorts (formerly called destroyer escorts), but were all redesignated as frigates on 30 June 1975 in the United States Navy 1975 ship reclassification and their hull designation changed from DE to FF.

The lead ship of the class was Bronstein, laid down 16 May 1961 and commissioned 15 June 1963, at Avondale Shipyards, Louisiana.

This class comprised the second generation of post-World War II destroyer escorts. These ships can be considered developmental vessels as many new systems were installed to test for future use, such as a new hull design, larger bow-mounted AN/SQS-26AX sonar system, and ASW weaponry. This class was a new design from the keel up, incorporating the FRAM improvements, and was specifically designed to operate the DASH drone helicopter. The sonar was later upgraded to the AN/SQS-26AX(R).

The top weight of the new ASW equipment and the large bow-mounted sonar made the Bronstein frigates too slow to operate with the ASW task forces for which they had been designed. Thus the US Navy decided against any further procurement of ships of this class. The later Garcia-class frigates were given a larger power plant and greater speed.

Ships

Only two ships of this class were built: USS Bronstein (FF-1037) and USS McCloy (FF-1038). Both were later sold to the Mexican Navy.

Bronstein

McCloy

At one time USS McCloy held the record for largest military drug bust at 49.5 tons of marijuana (late 1980s). A sea-going tug was forcefully boarded after an over night chase while the tug's crew tossed bales of cocaine overboard and weapons fire was released the following morning at dawn. One of the tug's crew was wounded by .50 caliber gunfire and was helo'd off. A Coast Guard detachment estimated the amount and an attempt was made to tow the tug to port. The tug had too much damage and sank in the night after several attempts to salvage her.

McCloy made many drug busts late in her life, received several citations and was painted with marijuana leaves for each bust.

McCloy sustained major damage during Hurricane Floyd in 1987 losing a large portion of its mast during the storm. Shelter was sought in the city of Morehead, North Carolina while the storm passed and damage was assessed.

Other notables include involvement in the rescue of the crew of the submarine USS Bonefish. One of the last US Navy diesel submarines, it had a battery compartment fire and was abandoned by her crew off the coast of Florida. McCloy ran lifeguard ops and eventually was designated the tow vessel to bring Bonefish to Charleston, South Carolina.
