Nice find Billy! My understanding is that the rockets were fired simultaneously. I can hardly imagine what that must have been like since unlike underwing rockets these actually would act as reverse thrusters for the airplane. No wonder that this unique combination was pretty much abandoned as far as I know after this.

Found this "In Action" photo. Looks like they could "ripple fire" as well.

Excellent build, Cecil!

When I was stationed at Elmendorf, the history there had a black and white photo hanging on the wall of Scorpion firing it's missiles. In the background was another Scorpion with its missiles "away."

As the color graphic you posted show, the missiles appeared to be rippled fired. I would think they would have to be ripple fired, as if they all fired at once, the aircraft would be in a world of hurt if one didn't fire. Ripple firing would allow any unfired missile to not affect the aircraft all that much.

Whether or not all missiles fired when the trigger was pulled, I don't know. But it still is a great build you did on your model.

I have a memory of the 2inch rocket packs used on Canberras (40 rockets per pack) - way back when the RNZAF had strike aircraft.
The rockets came out of the pack as a series of patterns - the explanation was that there had to be some space between the rockets so they didn't interact during the acceleration phase. I think there were 4 or 5 rockets per pattern. There was also a pause between firing patterns so the turbulence created by the previous pattern cleared.
The drawing of the F-89 looks as if something similar was used on those rocket packs.

I have a vague recollection that the Canberra fire control system allowed a single pattern of rockets to be fired.

Amazing what sticks in your memory....

Regards,

Charlie

I just couldn't resist this size comparison. One of these days I'll print out a scale cube but for now just seeing these two together cracks me up.

Both models are 1/72 scale. The tiggy was indeed a tiny airplane and the Scorp was just a beast of a fighter plane.

You think the Scorpion was compensating for something? :D
