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.
