Armament Development and Test Center B-57G Project PAVE GAT

One B-57G was modified to house a special bomb bay installation of one Emerson TAT-161 turret with a single M61 20mm cannon as a gunship under project Pave Gat. After delays in testing at Eglin AFB, Florida, due to competition for mission time from the Tropic Moon III B-57Gs, Pave Gat tests proved "that the B-57G could hit stationary or moving targets with its 20mm gun, day or night. Loaded with 4,000 rounds of ammunition, the Pave Gat B-57G could hit as many as 20 targets, three times as many as the bomb-carrying B-57G.
