History
The Auk class of naval ships were Allied minesweepers serving with the United States Navy and the British Royal Navy during the Second World War. In total, there were a recorded 95 Auk class minesweepers under Allied command during that time.
Thirty-two minesweepers were ordered by the US (as BAM-1 to 32) intending them to be supplied to the Royal Navy under Lend-lease but 12 were retained for USN use and given names and "AM" hull classification prefix. Those transferred were given "J" pennant number prefixs and formed the Catherine class
Eleven minesweepers of the Auk class were lost in World War II; only one (USS Skill) was sunk — by U-593.
Out of the reserved US Navy units, two were transferred to the Philippines as part of the US Military Assistance Program, these were USS Murrelet (renamed BRP Rizal) in 1965, and USS Vigilance (renamed BRP Quezon) in 1967.
Both ships were stricken in 1994, but were overhauled with assistance from Hatch & Kirk, Inc., and returned to service in 1995-1996. Recent upgrades includes a satellite radio dish for communications. As of 2008, both ships are still on the active roster of the Philippine Navy, and are assigned with the Patrol Force.
With 40 years of active duty with the Philippine Navy, both have been involved local and international crisis, exercises, and incidents.
