LOCKHEED AC-130E “PAVE SPECTRE”

Posted 1/8/2009 Printable Fact Sheet

Project "Pave Spectre" was the USAF program to acquire and modify C-130Es to gunship configuration. The initial plan called for converting eight aircraft, two prototypes (S/N 69-6567 and 69-6568) and six operational planes (69-6569 to 69-6574) for delivery no later than Jan. 1, 1972, since the gunships were needed for Commando Hunt VII -- interdiction of enemy trucks and sampans moving through the panhandle of Laos (Steel Tiger area). Six additional aircraft were reserved for Pave Spectre conversion; however, only three were modified (S/N 69-6575 to 69-6577).

The AC-130E was an improved version of the AC-130A "Pave Pronto" aircraft. The C-130E was equipped with more powerful versions of the Allison T-56 turboprop engines. The aircraft also had a maximum gross takeoff weight more than 30,000 pounds more than the AC-130A. Consequently, the AC-130E had more armor plating and could carry additional ammunition and equipment.

The AC-130E had an improved digital fire control system based on the LTV A-7 Corsair II system. In using an existing FCS, the program managers expected to take advantage of the training, maintenance, supply and logistics already in place to minimize the chances of a deployment delay for the operational aircraft. The FCS also featured a head up display gunsight for the pilot and a moving map display for the navigator. The AC-130E retained the low light level television, forward looking infrared, Black Crow ignition sensor, moving target indicator and beacon tracking system successfully used on the Pave Pronto AC-130A.
