For use in northern frontier defense, across border stand off anti-missle defense as well as ground support missions, supply introdiction in any weather day or night, early warning, and just generally kick rear and take names when it counts these are the aircraft for extended ground opperations.

They will make Hezbollah wet their pants and scream like little girls!


The AC-130H Spectre gunship's primary missions are close air support, air interdiction and armed reconnaissance. Other missions include perimeter and point defense, escort, landing, drop and extraction zone support, forward air control, limited command and control, and combat search and rescue.
These heavily armed aircraft incorporate side-firing weapons integrated with sophisticated sensor, navigation and fire control systems to provide surgical firepower or area saturation during extended periods, at night and in adverse weather.

AC-130U Spooky


Continuing the distinguished combat history of side-firing AC-130 gunships, the new AC-130U Spectre gunship is being fielded as a replacement for the AC-130A aircraft. This program acquires 13 new basic C-130H aircraft for modification and integration by Boeing to the AC-130U Gunship configuration. The AC-130U gunship airframe is integrated with an armor protection system (APS), high resolution sensors (All Light Level Television (ALLTV), infrared detection set (IDS) and strike radar), avionics and EW systems, a sophisticated software controlled fire control system, and an armament suite consisting of side-firing, trainable 25mm, 40mm, and 105mm guns. The strike radar provides the first gunship capability for all weather/night target acquisition and strike.

The acquisition program for this new gunship evolved from a Congressional mandate in the mid-1980s to revitalize the special operations force capabilties. Following the contract award to Rockwell in July 1987, the aircraft was first flown on 20 December 1990. FY92 procurement funding was increased to provide the 13th aircraft to replace the AC-130H lost during Desert Storm. Upon completing an exhaustive flight test program at Air Force Flight Test Center from 1991 to 1994 the first aircraft was delivered to AFSOC on July 1, 1994. Boeing’s contract includes: concurrent development, aircraft production, flight test, and delivery. All aircraft have been delivered and the program is transitioning to the sustainment phase. A competitive contract for sustainment was awarded in July 1998.
The AC-130U is the most complex aircraft weapon system in the world today. It has more than 609,000 lines of software code in its mission computers and avionics systems. The newest addition to the command fleet, this heavily armed aircraft incorporates side-firing weapons integrated with sophisticated sensor, navigation and fire control systems to provide surgical firepower or area saturation during extended loiter periods, at night and in adverse weather. The sensor suite consists of an All Light Level Television system and an infrared detection set. A multi-mode strike radar provides extreme long-range target detection and identification. It is able to track 40mm and 105mm projectiles and return pinpoint impact locations to the crew for subsequent adjustment to the target. The fire control system offers a Dual Target Attack capability, whereby two targets up to one kilometer apart can be simultaneously engaged by two different sensors, using two different guns. No other air-ground attack platform in the world offers this capability. Navigational devices include the inertial navigation system (INS) and global positioning system (GPS). The aircraft is pressurized, enabling it to fly at higher altitudes, saving fuel and time, and allowing for greater range than the AC-130H. Defensive systems include a countermeasures dispensing system that releases chaff and flares to counter radar infrared-guided anti-aircraft missiles. Also infrared heat shields mounted underneath the engines disperse and hide engine heat sources from infrared-guided anti-aircraft missiles.

The AC-130U P3I program develops and procures modifications that correct software and hardware deficiencies of the AC-130U fleet discovered during flight tests and that were outside the scope of the original FY86 contract. These modifications will include the following: combine all necessary software requirements for the System Integration Test (SIT) system and hardware and software improvements for the APQ-180 strike radar system; upgrade the Tactical Situation Map; improve core avionics and computers required for the multi-mission advanced tactical terminal/integrated defense avionics system installation; upgrade the EW suite; and modify the software/hardware required for the trainable gun mounts.

The AC-130H/U, AAQ-26 Infrared Detection Set (IDS) Upgrade program modifies the optics on the AN/AAQ-17 Infrared Detection Set (IDS) currently installed on 13 AC-130U and 8 AC-130H Gunship aircraft to the AN/AAQ-26 configuration. The AC-130U wiring, Operational Flight Program (OFP), Control Displays Program (CDP), Trackhandle, bus multiplier (BMUX), control panels, and variable slow rate feature will be modified. The AC-130H will also be modified. Support equipment, spares, and tech data for both aircraft will be modified as required to support the AN/AAQ-26 configuration. Mission requirements dictate a significant enhancement in target detection, recognition, and identification ranges to decrease aircraft vulnerability. A sole source fixed price incentive contract was awared to Raytheon for design, modification, and installation; with directed sub to Lockheed Aerospace Systems Ontario (LASO) for integration of the AN/AAQ-26 on the AC-130H and Rockwell for software integration of the AN/AAQ-26 on the AC-130U.

The United States Special Operations Command (USSOCOM) has a requirement for a C-130 engine infrared (IR) signature suppression system to provide Special Operations Forces (SOF) C-130 aircraft with an IR signature reduction equal to or better than existing systems at a lower cost of ownership. The primary difficulties with present suppressor systems are low reliability and poor maintainability. This C-130 Engine Infrared Suppression (EIRS) Program system will be used on AC-130H/U, MC-130E/H/P, and EC-130E aircraft. The key requirements for the Engine IR Suppression system are: (a) improved reliability and maintainability over existing systems to result in lower total cost of ownership; (b) IR signature suppression levels as good as the current engine shield system (aka. Tubs); (c) no adverse impacts to aircraft performance and ability to accomplish SOF missions; (d) complete interchangeability between engine positions and identified aircraft types. The suppressor is expected to be a semi-permanent installation, with removal being primarily for servicing, allowing the aircraft to perform all required missions with the suppressors installed. There will be up to two competitive contracts awarded for the initial phases of development with a downselect to one contractor for the completion of development and production. The contract will contain fixed price options for procurement, installation, and sustainment of the system.

The Directional Infrared Countermeasures (DIRCM) program develops and procures 60 systems and provides 59 SOF aircraft (AC-130H/U, MC-130E/H) with a DIRCM system capability. The DIRCM system will work in conjunction with other onboard self-protection systems to enhance the aircraft’s survivability against currently deployed infrared guided missiles. Growth is planned to add a capability to detect and counter advanced threats.
