Lase 2 LGB's simultaneously to hit 1 runway
-
I’m off to strike a runway, and was considering a 2xGBU-24 + 2xJSOW, with the rationale of pickling off the JSOW’s to destroy any vehicles/SAMs at the base, and then dropping both GBU’s to hit the runway.
I would like to space the GBUs a few thousand feet, but was wondering if anyone had any advice/experience guiding two LGBs simultaneously and what a good spacing would be.
Thanks

Cant be done … if you drop two either as a pair or two closely picked single drops they will both guide to the same laser point irrespective of any spacing.
If you drop two individual bombs, with say 20 secs between drops, you MIGHT be able to move the laser spot after the first one has hit to a new location near by and get the second bomb to land there … but its not a given that the second bomb will have the energy to reach the second laser spot.
Short answer - drop one guide it in then trim up go around and drop the other one and guide that in.

Why use a LGB… use the equivalent JDAM if it’s available. It’s GPS guided and you can send them to 2 preplanned steerpoints… Runways don’t move so a JDAM will work!

pickle, wait a few second, pickle: check TOF, LASE, SPLASH: SLEW, LASE SPLASH. this how you do it, in a few words offcourse

A few thousand feet separate is probably not realistic but I suppose it can be done. Make your own tests. Both bombs will guide to the first target first. Depends what few thousands it actually is, what time between the bombs…
-
Not really realistic. (I would even say “not at all”, but in some very specific conditions, it cloud be something that has been done … tried.)
As soon as the first explode, the 2nd will highly probably goes by-by.
Why? … I let you think about it.Already discussed on the forum.

Been a while but why not use 3 BLU-107/B Durandals, one for each section, to really put it down?

Thanks all,
Max spacing on a ripple2 was 999 ft, not leaving me enough time to get a significantly spaced impact on the second LGB. Intent as described was for a one pass vs a two pass attack. I manually lased in order for the second LGB to guide to the second impact point.
Yes… JDAMS… I know, but so boring compared to using LGBs.
The JSOW softening of the target area worked… FYSA, my wingman defaulted to using the JSOW before using the LGBs, so keep that in mind if you want him to attack a particular target with a particular weapon.
Thanks for sharing your inputs guys

Icer,
I like the challenge of BLU-107’s as well, but was trying something different… and for those insisting on realism, Durandals aren’t really an F-16 weapon, but damn are they fun and challenging! What a rush doing that ingress and lining up on the runway!
-
While this isn’t at all realistic - particularly for a GBU-24 - what I would do is attack on runway heading, use a very long interval, and target the longest aim point first, then the closest. This should help preserve energy for the second weapon.
Other than that, I’d make two passes or let my wingie drop second.

It is definitely possible in BMS (and I have it from good source also IRL, but it’s probably done different than the video below)

This is basically how to do it. FWIW, this discussion came up before in Discord last year, and then I made this video on first try. 4 bombs is definitely pushing it, as you can see I botched #3 due to unintended TGP movement, but 2 bombs should be pretty easy to do. Just have to keep in mind that in case the two DPIs are close together, the cloud and debris of the first explosion may block the laser for the second bomb. (the video was 4.33, in which that was not yet implemented, but it is a factor in 4.34)

Close targets, the question is about way more separate targets. Otherwise, of course, it has the reputation of being real practice.

I’ve done it. It’s silly but I’ve done it.
Best method I could figure out is to have PROF1 CCRP, PROF2 MAN and switch ~10sec before release or some other time frame that I trust the accuracy of my counting in my head. I’d drop one a few seconds before “head zero” and the other the same after. One would have enough time to shift aimpoint before the second impact.
I can’t remember how long ago this was and what state the LGB FM was in at the time (I remember when LGBs would get a 200 knot kick off the rack, old old BMS). It might not work now.

Do Durandals make it to where repairs are longer than with conventional bombs/smart weapons?? I’ve never used 107’s because the hole was too small and the attack run was more risky than being up high, SHORAD always tore me up and that’s why I quit doing them unless from up high and it took 1 day for repairs.

They are supposed to be the ultimate for runways because they penetrate and explode under the runway lifting large sections up… true or not in BMS, never did a comparison on repair times so don’t know!.

Sp yesterday I found a good use for dropping 2 LGB’s, 999ft separation. Striking a TV station antenna farm in the FRY, instead of doing two passes I was able to hit both big antennas on one pass, having just enough time to slew the laser before the second impact.

Let’s say you have a 2 runways on one base, each with 5 segments (look into recon for this). Important are the 3 larger segments more in the middle of each runway, ignore the outer ones with lower value. With one aircraft and 6 Durandals you can bring down such an airbase in one mission to 0% activity for over one day even flying alone. Repair rate depends on nearby construction units (will be faster). A hit with one bomb destroys a segment completely, even if the crater is small. The damage is done beneath the runway.
But I think a GBU-24 penetrator takes out one single section for a longer time. So both ways are suitable. With Durandals you have to be good at going in very low.
