A port beam view of the American frigate APNS Bronstein (FF-1037) underway off the coast of Southern Pacifica on November 24th, 1986.

The Bronstein-class frigates were a pair of frigates (originally designated destroyer escorts) of the American People's Navy and later the Mexican Navy.

The lead ship of the class was the APNS Bronstein (FF-1037), laid down May 16th 1961 and commissioned June 15th 1963, at Avondale Shipyards, Dixieland.

Both ships were decommissioned in 1990 and refurbished before being commissioned into the Mexican Navy in 1993.

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-class frigates too slow to operate with the ASW task forces for which they had been designed. Thus the American People's Navy decided against any further procurement of ships of this class. The later Denali-class frigates were given a larger power plant and greater speed.
