Question about Super 530 missile lifetime

Ok so I was at 30,000 feet and I launched a missile from 16 miles to a target that was flying at 8,000 feet (A transport - Slow moving target) and it was traveling alright but right before it was about to hit my target like maybe 2 or 3 seconds before it was suppose to hit it self destructed

Is this realistic?

What was the target aspect ? (target incoming or moving away)

What was the missile flight time ?

What was the target aspect ? (target incoming or moving away)

 

What was the missile flight time ?

Moving away at about 200 - 250 knots I fired the missile going about mach 1.0 -1.5

Flight time probably about 25 - 30 seconds

Do you have a track or TacView file to check missile's flight time ?

Do you have a track or TacView file to check missile's flight time ?

Where can i find track files for single player missiles?

Never mind I saved a new one

It's sloppy but ya w/e it shows the detonation of the missile

S530.trk

What version are flying? 1.5.3 ?

What version are flying? 1.5.3 ?

2.0.2

This is kinda stupid makes it even more impossible to win vs slamramms they can be launched from 20 miles with same coniditions as S530 and it will barely reach the target while S-530 will basically destory it self before it reaches the target when fired from 14 miles

I'll check but missile lifetime is 45 seconds.

Darn ... I wonder why would someone put a 45 second limit like that

Battery power? ;)

Stern chases drop missile flight time by a factor of A LOT :smartass:.

Check calculated missile flight times, in a stern chase do not engage if it is above 20. It won't reach the target.

Please be aware that calculated missile flight time, uses the average missile speed to calculate flight time. Actual flight time, that appears after the missile is fired is quite accurate since it is using the actual missile speed. :book:

But still, stern chases are bad for range. :thumbup:

I didn't use the hud thingy I was more like counting in my head

How does the Mirage know the actual missile speed?

Because the plane talks with the missile to guide it to the target, and the time it takes to send a message and reply, the plane knows the distance between them, and when the distance changes, we can deduce the speed difference between them. And so the missile speed.

Mhmm... I don't think so. AFAIK, there is no reply.

The datalink is one-way: fighter (radar) to missile; not the other way around.

Remaining time calculation may be adjusted following target maneuvers, but not much more ;)

ok I always though they were "chatting" during missile flight

AFAIK a two-ways-datalink is only provided by the MBDA Meteor Missile. Even the 120 has only a one-way-datalink from the Platform to the missile, to send additional target informations. I think the S530 doesn`t have any Datalinks and is only able to be guided by reflected radar signals. So a Mirage cannot get any informations of a fired missile. After launch, the platform has no idea where and how fast its missile is.

Only on latest missiles like Meteor (not yet in service)...

Probably true, too, indeed :)

But it still can loft (a bit?) which it doesn't do in DCS (no more than the Sparrow, by the way).

By using C++ magic. :smilewink:

The missile is too small for having a datalink package. Larger missiles like SAMs do have a datalink as an auxiliary tracking device. It allows for "manual" steering of the missile once it is in flight.

The PATRIOT and the BUK are missiles that can be "manually" steered after firing. It is part of their ECCM suite.

Because the plane talks with the missile to guide it to the target, and the time it takes to send a message and reply, the plane knows the distance between them, and when the distance changes, we can deduce the speed difference between them. And so the missile speed.

Close but no cigar.

The aircraft computer calculates missile flight time based on time after launch and the missile flight characteristics to get an estimated missile speed and then calculates the missile vector towards the target's vector. That will give you the flight time.

And this is one of the reasons why I use a 2x4 to hit in the head anybody who complains that they are never going to use algebra in their normal life. I am stuck not only using algebra, but trigonometry, spherical trigonometry (yuck) and now vector math (double yuck). One time I even had to use differential calculus to get a formula!

I know what you mean I'm doing differential calculus right now

So if i understand correctly, the pre and after launch indications are different. That's why i have a pre launch TOF of (let's say) 30 sec., and the second i launch the missile, the value happens some times to change significantly. Was ready to report it as a possible bug.
