GP-19 Extended Capacity Pod

Also known as
  • GP-19 ECP
  • GP-19 Extended Gun Pod
  • Fulcrum GP-19 Extended Capacity Pod

The GP-19 Extended Capacity Pod is Fulcrum Concepts' higher-capacity GP-19 aircraft gun-pod configuration for the GAU-19 .50 caliber Gatling gun. Public documentation covers product specifications, accessory compatibility, and host-aircraft integration, while the record does not document confirmed conflict use of the ECP itself.

Gun, Ammunition, And Aircraft Control Interfaces

Fulcrum presents the ECP as a higher-capacity podded aircraft installation for the GAU-19 gun family, its linked .50 caliber ammunition path, and Fulcrum's aircraft control equipment.

Why the support equipment matters

Fulcrum separately lists GP-19 ECP compatibility for its GCP/AIU equipment pallet, GAU-19/A-to-/B conversion hardware, and pod storage rack, which supports the ECP as part of a wider aircraft-integration and sustainment set rather than a standalone gun mechanism.

Integration And Sustainment Context

Fulcrum's ECP literature emphasizes a larger magazine and aircraft-interface package rather than a different gun. The public fact sheet gives an 861-round store capacity, 220-pound empty weight with gun, 462-pound loaded weight, 6,400-7,000 rounds before battery recharge, and 14-inch mounting lugs.

Aircraft interface

The ECP is described as interfacing with host aircraft through built-in gun-control battery equipment, 14-inch mounting lugs, optional last-round override, jettisonability, and integrated bore-sight adjustment.

Control equipment

Fulcrum's GCP/AIU equipment pallet can interface with mixed GP-19 ECP, GP-19, GAU-19, DAP-6, M134, and rocket-pod control configurations, giving the pod a documented place in a multi-station aircraft armament-control set.

Sustainment equipment

Fulcrum's GAU-19/A-to-/B conversion notes a relocated timing pin for use in GP-19 and GP-19 ECP pods, while the pod storage rack can hold GP-19 or GP-19 ECP gun pods with optional GCBU charging provisions.
