High Speed Ramp (shuttering fixed to the sides of the ramp).
High Speed (cargo) Door (slightly different actuator(s)with or without fuselage rib/skin changes).

C130K and J, 185 Kts for the door only.

So what type of ramp is this :E

Cameroon Air Force C-130H damaged after overshooting runway

Thank you for the explanation of those abbreviations. No such 'go faster' devices on the 'K' during my time on the a/c. We even had to bunt the a/c slightly to get the cargo door into the uplock.
Interesting about the speed of the C130J. IIRC this could be north of the VNO of the 'K.'

Long article from the HERC crew about the collision by the F-35B. Appears the F-35B pilot closed TOO FAST but there could be other explanations but not in this good story from the SUPER J crew:

Raider Five Zero on Fire: An Impossible Story of Survival 2 Miles High

"...The pilot of Bolt 93 replied, “Yeah, stand by.” He later told investigators he then went “heads down,” checking bingo math and distances on a kneeboard as the formation continued the slow turn back to the south.

But that turn was now complete. Just as the pilot of Bolt 93 went “heads down,” Jones began to roll Raider 50 onto a straight heading. There is no rule in Marine aviation that requires tanker pilots to announce turns. In combat, air refueling is often done with no radio chatter at all. As Raider 50 leveled out, Bolt 93 stayed in a 17-degree left turn — directly toward Raider 50.

A loadmaster called out on the tanker’s intercom: “Nine Three’s coming in fast!” He turned away to shelter from the impact when the jet was about 10 feet from his window.

The fighter tore into both of the tanker’s engines, shattering the propellers. The doomed jet twisted into the side of the tanker’s fuselage, tearing a gash through the plane’s landing gear compartment.

At 4:03 and 55 seconds, the pilot of Bolt 94 realized a disaster was unfolding with Bolt 93 in an “uncontrolled vector” toward the tanker. He called out helplessly, “Easy, easy, easy, PUSH OVER, PUSH OVER, PUSH OVER!” —an instruction equivalent to “Dive!”

Inside Raider 50, the loadmaster on the right side simply yelled into the intercom: “Oh ****, oh ****, oh ****!”

At 4:03:57, 13 seconds after Bolt 93’s pilot went “heads down,” the F-35’s nose slammed into the bottom of Raider 50’s right wing at 16,920 feet and 264 mph. The fighter tore into both of the tanker’s engines, shattering the propellers. It also ripped loose the hose pod, causing a torrent of fuel to begin spraying out. Finally, the doomed jet twisted into the side of the tanker’s fuselage, tearing a gash through the plane’s landing gear compartment.

In Bolt 94, the pilot watched a momentary fireball engulf the F-35 and most of Raider 50’s right wing. When it cleared, Bolt 93 was gone, tumbling away. In the next minute, the pilot of Bolt 94 called out three times for his wingman to eject. He got no response...."
