The Rizal class is a ship class of two patrol corvettes currently in service in the Philippine Navy, and its largest class of corvettes.  

These ships were formerly used by the US and Royal Navy as Auk class minesweepers 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 while those transferred were given "J" pennant number prefixs which formed the Catherine class.  

After the war, some of these ships found their way in to US Navy researve units. Until in the 60's , under the US Military Assistance Program, two of which were transfered to the Philippines.  These were: USS Murrelet in 1965 (renamed BRP Rizal); and USS Vigilance  in 1967 (renamed BRP Quezon).

When these ships were transfered to the Philipiine Navy, the two vessels have undergone upgrades and modification, and were categorized as corvettes.
