el Martin PBM Marinero fue un bombardero de patrulla estadounidense volando barco de la Segunda Guerra Mundial y el período de la Guerra Fría temprana. Fue diseñado para complementar el PBY Consolidado Catalina en servicio. Se construyeron un total de 1.366, con el primer ejemplo volando el 18 de febrero de 1939 y el tipo entrando en servicio en septiembre de 1940.

The Navy’s Heavyweight Hunter
el Martin PBM Marinero was the larger, more heavily armed, and arguably more capable twin-engine cousin to the famous PBY Catalina. While the Catalina was the “eyes” of the fleet, the Mariner was its “fist.” Designed as a long-range patrol bomber and anti-submarine platform, the Mariner was a massive, gull-winged beast that could carry a larger bomb load than a B-17 Flying Fortress. It was built to endure the brutal conditions of open-ocean landings, serving with distinction in both the Atlantic and Pacific theaters as a sub-hunter, rescue craft, and transport.

Design Engineering: Gull Wings and Engine Nacelle Bays
- The “Gull” Wing: The PBM featured a distinctive “inverted gull wing” design. This was done to raise the massive engines as far away from the water spray as possible during take-off and landing, protecting the propellers from damage.
- The Bomb Bay Nacelles: In a brilliant bit of engineering, the Mariner’s bomb bays weren’t in the fuselage—they were located inside the engine nacelles. This kept the main hull clear for crew, fuel, and survival gear.
- Dreadnought Defense: The Mariner was bristling with guns. It featured powered turrets in the nose, dorsal (top), and tail positions, making it an incredibly difficult target for enemy fighters to approach.
- Retractable Floats: To reduce drag in flight, the stabilizing floats on the wingtips retracted inward. Unlike the PBY Catalina, which folded its floats to become the wingtips, the Mariner’s floats retracted into the wing structure itself.
Operational History: Submarines and “Dumbo” Missions
- U-Boat Scourge: In the Atlantic, the PBM was a terrifying sight for German U-boat crews. Equipped with advanced radar in the “teardrop” pod above the cockpit, it could hunt subs at night or in thick fog, ending the career of many Type VII and Type IX submarines.
- The “Dumbo” Rescue: In the Pacific, the PBM flew “Dumbo” missions—named after the flying elephant—to rescue downed pilots from the ocean. Its large size allowed it to carry a significant number of survivors and a full medical suite.
- The Flight 19 Connection: A tragic part of the Mariner’s history involves the “Bermuda Triangle” legend. A PBM-5 sent to search for the missing Flight 19 Avengers in 1945 exploded in mid-air shortly after take-off, likely due to a fuel vapor leak—a known hazard in early Mariner models.
- JATO Power: To get off the water when overloaded or in calm seas (where “suction” keeps the hull stuck to the water), the Mariner often used JATO (Jet-Assisted Take-Off) rockets strapped to the fuselage for an extra boost of thrust.
