== Overview ==

The '''PB-37 Sea Duck''' is the primary maritime patrol and anti-submarine warfare aircraft of the [[Gondaran Air Corps]].

Designed as a long-range flying boat capable of operating from coastal anchorages, inland lakes, rivers, and sheltered harbors, the Sea Duck combines reconnaissance, anti-submarine warfare, anti-shipping capability, troop transport, and search-and-rescue functions into a single aircraft.

An initial production run of 192 aircraft equipped twelve maritime patrol squadrons distributed throughout Gondara's states and coastal regions.

----

== Design Philosophy ==

The Sea Duck was developed to address Gondara's enormous coastline and maritime approaches.

Key design goals included:

* Long-range ocean patrol capability
* Anti-submarine warfare operations
* Maritime strike capability
* Search and rescue operations
* Limited troop and cargo transport
* Operation without reliance on conventional airfields

The aircraft's flying boat hull allows operations from virtually any sufficiently calm body of water.

|}

----

== Armament ==

=== Offensive Armament ===

* 2 × 25mm Revolver Cannons

The cannons are mounted high on the forward fuselage to reduce exposure to water spray and salt contamination.

The weapons are controlled directly by the pilot.

----

=== Defensive Armament ===

* 1 × Powered dorsal turret
** Twin 12.5mm Heavy Machine Guns

The dorsal turret provides defensive coverage across the upper hemisphere.

----

=== Anti-Shipping Weapons ===

* 2 × 1,900 lb aerial torpedoes

Mounted beneath the inboard wing sections.

----

=== Anti-Submarine Weapons ===

* 6 × 650 lb depth charges

Carried internally within the lower hull weapons bays.

----

== Sensor Suite ==

=== Air-to-Surface Vessel Radar ===

The PB-37 carries a downward-searching ASV radar system mounted within the lower forward hull.

The system is designed to detect:

* Surface vessels
* Submarines operating on the surface
* Coastal installations
* Convoy formations

----

=== Magnetic Anomaly Detector ===

A tail-mounted MAD boom extends from the rear of the twin-boom structure.

The system detects disturbances in the Earth's magnetic field caused by submerged submarine hulls.

----

== Transport Configuration ==

The Sea Duck incorporates a modular cargo and transport compartment.

Standardized internal rails permit rapid conversion between operational roles.

When configured for transport missions the aircraft can carry:

* 12–14 fully equipped infantrymen
* Routefinder teams
* Cargo pallets
* Medical evacuation litters

Troops embark and disembark through the rear loading ramp.

----

== Special Features ==

=== Rear Loading Ramp ===

A hydraulically operated watertight rear ramp permits:

* Cargo loading
* Troop deployment
* Casualty evacuation
* Sea rescue operations
* Beach landings

The feature greatly expands the aircraft's operational flexibility.

----

=== Wet-Float Fuel System ===

The wingtip stabilizing floats also function as auxiliary fuel tanks.

During flight the floats fold upward and outward against the wingtips, reducing drag while increasing fuel capacity.

This arrangement significantly contributes to the aircraft's exceptional patrol range.

----

== Operational Role ==

The PB-37 serves in numerous mission profiles:

* Maritime reconnaissance
* Convoy escort
* Anti-submarine warfare
* Anti-shipping operations
* Search and rescue
* Troop transport
* Disaster response
* Coastal surveillance

The aircraft's versatility makes it one of the most important force multipliers in Gondaran service.

----

== Summary ==

The '''PB-37 Sea Duck''' serves as the backbone of Gondaran maritime aviation. Combining the capabilities of a patrol aircraft, anti-submarine platform, transport aircraft, and rescue vehicle into a single flying boat design, it provides Gondara with a flexible and long-ranging maritime patrol capability unmatched by most contemporary aircraft.
