One can get confused as to which deignation AC have, even after having over 4000hrs on them... I have over 4000 hours fixing them...
No, sorry to disagree with you, but they are KC-130s, most likley R or T models. After having over 4000 hours in one they become part of your life. HC-130s have a nose in the shape of a wedge, as well a a pronounced hump in the back aft of the cockpit. area Those noses are rounded. Also note the tri coloring. AF birds, including HC birds, are single color grey or camo.
