An American company (ATK, Alliant Techsystems Inc), is modifiying the same basic airframe used for the Coast Guard HC-144 (the EADS CASA, now Airbus Military, CN-235) into a miniature AC-130 for the Jordanian Air Force. Source.
“ATK will install and integrate electro-optical targeting systems, a laser designator, aircraft self-protection equipment, and an armaments capability that includes Hellfire laser-guided missiles, 2.75-inch rockets, and a M230 link-fed 30mm chain gun. ATK’s M230 family of guns serves on the Apache helicopter….ATK’s scope of work includes development, systems integration, aircraft modification, and testing. Work will be performed in Jordan and at ATK facilities in Fort Worth, TX, Mesa, AZ and Pelham, AL.”
Looks like if we ever want to add an “airborne use of force” to these aircraft, there is a source that will have already had the experience.
