Harvest HAWK Completes Phase One Testing: "Harvest HAWK is a modular roll-on, roll-off weapons system for the KC-130J consisting of a Fire Control Console in the aircraft's cargo compartment, the Target Sight Sensor (TSS) mounted in the left under wing fuel tank and a launcher for four Hellfire missiles mounted on the left hand refueling pylon.
NAVAIR is working a complimentary effort to test and deploy the Standoff Precision Guided Munition (SOPGM) as a stand alone capability for Harvest HAWK. The 30 mm cannon, which will be mounted in the left side troop door, has been deferred to a later block upgrade."
