On display at Pima Air & Space Museum. The PBM Mariner was designed by the Glenn Martin Company to challenge the PBY Catalina. It was superior to the PBY, though it served in smaller numbers in WW2. The gull wing PBM-3C was powered by two 1,700 hp Wright R-2600-12 Twin Cyclone engines, which were upgraded to the "C" Series 2,100 hp P&W R-2800-34 radials on the PBM-5A amphibian with a retractable tricycle undercarriage. The PBM-5A was the final Mariner variant flown by the USN and USCG in the SAR role. This is the only surviving Mariner in the markings of VR-21 based at NAS Barbers Point.

Only survivor of the type. Delivered to the US Navy as 122071 in 1948. Sold in 1956 and registered as N3190G. Stored at Thermal, CA. Acquired by the National Air and Space Museum in 1972. Loaned to Pima Air and Space Museum. Restored and repainted into US Navy colours as 122071 by 2000.
