A PBM-5S2 "Mariner" from VP-731 was attacked on July 31, 1952, by two Chinese MiG-15s over the Yellow Sea resulting in two crewmembers killed and two more seriously wounded. The PBM-5S2 suffered extensive damage but was able to make it safely to Paengyong-do, Korea. The PBM-5S2 was based at Iwakuni, Japan.
On November 7, 1953, a PBM-5A ""Mariner" was over the Yellow Sea. The entire crew were lost. Three days later, the People's Republic of China claimed to have shot down a U.S. aircraft over the area. The possibility exists the Chinese had given the wrong date.
