Hey has anyone figured out WTH the settings in Cruise Activity on a weapon actually means?

We have Primary Dist / Alt and Secondary Dist / Alt

Presumably at X distance it flies at X altitude and Y distance at Y altitude but I remember messing with these way back when and getting terrible results so I never really went into figuring out what they mean.

I would love to make a cruise missile like the AGM-86/BGM-109 hug the ground and fly as well as something like the Kh-15 / AIM-54 fly up at maximum height and then come down.

You cant get a cruise missile to go below standard elevations because they wont do terrain avoidance like an AI aircraft will so they will simply fly into the side of a mountain instead of skirting over it to target...

I have built a cruise missile that is actually an aircraft that will do terrain avoidance and I can set minimal altitudes via waypoints and set minimal altitudes the cruise missile can fly at (0) in the PT file and then set the fuel to 0 at the attack point after I have have it drop a load of invisible CBUs to mimic the dropping of a submunition warhead...

Great to use to simulate a mass cruise missile strike to try to intercept and it allows SAMs, AAA, and ships Phalanx to shoot them down as well...

That could work for a mission where you have to engage and shoot them down; however, my goal was to have the cruise missiles launched from ships to do some sort of different behavior as well as allow AIM-54s and AIM-120s to fly up near 80,000 ft.

You can make cruise missiles targetable and engageable so that they can be shot down (as JT files) but they're tricky and you can't detect them on radar if I remember right. I always remember getting them on IR or visual.

You can detect them on radar and IR if you increase the cross section enough for both forms of tracking.... but you cant make them do terrain avoidance.

Ah so you can get them on radar - it's been a while obviously. Yes I know they won't do the terrain avoidance. Moreover though do we know what the values correspond to in the Toolkit categories?

Yes and even my old tip files - never found much though.

Are the cruise missile speed values in foot per second or nautical miles per hour or just regular miles per hour? I seem to remember something about that being FPS...

At least it is in the PT File...

By the way have you checked the help files in the FATK?

Cruise Altitude = increments of 250 feet (above the target)
Found it out by accident, when I was testing some SS-Ns flying at 10,000 feet and realized cruise alt was set to 40.
So I moved it up to 66 and sure enough they went up to 16,500 feet.

Still not sure how distance correlates.

I have the following:
> Primary Dist = 50
> Primary Alt = 66
> Secondary Dist = 25
> Secondary Alt = 1

Basically they do a near vertical drop onto the target.

It's supposed to be this (at least per the help file)
Primary = If distance is greater than this, do this
Secondary = If distance is greater than this but less than primary do this

Been testing a little on the AIM-54C.
Put it up to 80 (20,000 feet) and just nothing hit
Down to 40 (10,000 feet) and some better success

The distances are odd because no matter what I change the secondary to, it doesn't start its descent until it's almost on top of the target.

Yes I figured that out as well... Allows you to build a cruise missile that will fly high enough to skirt the mountain tops inland and then when closer to a ship off shore drop down and sea-skim at 250 ft... Unfortunately my testing of aircraft as cruise missiles only works if you edit the mission file and give it just enough fuel to get it to the target where it runs out of gas and crashes.. Hopefully into the target if it isn't shot down first by AAA, SAMs, and aircraft... You have to guess at fuel levels to use the fuel command at the start of the mission file to get it to work well enough... The trick is to get it to drop invisible cluster bombs so it looks like the missile warhead went off...

Pretty neat.
Yeah I was working on it mainly for AShMs (particularly the Soviet ones that come down from high up) so the terrain situation wasn't too big of a problem.
I was trying to put AIM-54s and AIM-120s on a very high lofted trajectory but they kept not coming down to the target and missing or coming down too late and coming behind it.
I think I still need to understand the distance aspect.

How high of an altitude are you using? Soviet antiship missiles, the big ones, flew a very straight course to the target. They just came straight in and lost altitude in a direct line to target.

So I was working on a few actually that fly various trajectories.

The P-700 or SS-N-19 flies at 14,000 - 17,000 meters for ranges exceeding 100 km and then come down to 25 meters for the final strike and I wanted to have the Kirov's engage at long range vs. shorter range so that it puts a little more pressure to sink them in missions.

The P-500 or SS-N-12 does a little bit of a tricky move in that 1 missile flies around 4,000 - 7,000 meters and the other 7 stay down low around 100 meters. So I am going to simulate 1 missile flying up high and the rest being down low (just 2 different missiles with 2 different cruise settings loaded into the tubes).

Most of the others just fly down at > 100 meters.
