Spacing out Durandals
-
See the Icarus pictures just don’t make sense to me. The bombing pattern is showing all the way back to the ends of the runway but at a pickle spot right in the middle of the runway you have already PAST the initial bombing impact points. How are the bombs flying BACKWARDS to make patterns like that?
-
It’s not really flying backwards, more like he’s releasing from a higher altitude. I doubt you can get that result from less than 1,000 ft AGL.

Released at 1500 feet AGL at 500 kts in this picture.
500 feet needs to be manual. 12 bombs at 800 feet spacing requires at least 1500 feet. 6 bombs you can go much lower.
When you pickle the center of the runway your jet is not even over the threshold. They start coming off immediately and start dropping on the front of the runway.

Ah yes there was the assumption of a low pass not 1500 feet AGL.

600kts 500 feet, ripple 12 800 spacing, aim a little early.

Personally I prefer manual. Gives you more options if things don’t go as planned.
This is not the purpose of the ripple mode anyway considering that IRL a runway is not attacked like this …
-
This is how durandals should be used. Flying right down the axis of the runway would be heavily defended against and would not work IRL. BTW, what’s the drag factor on those 12 BLU’s?
-
Ok, so supposed usage of the Durandal is to cut off the runway at 1 point like using a saw?
Spacing at 30ft should do the trick? -

Yes, I was just doing test runs to show what is possible in BMS, not whether it is correct or even realistic. I have no idea what is realistic, my only knowledge of what is realistic is what Stubbies tells me.;) I do not and have not used ripple on runways in BMS. BTW with 12 ripple 600kts 500AGL pass the pylons were protesting loudly. So its possible, but most inadvisable.

Well ironically now a days and with BMS directly into consideration how it handles runways the best way to attack those would be with JDAMs with penetrating warheads (GBU31(v)3/B) with precision steerpoints at the different runway bits. Depending on the runway the 3 or 4 precision steerpoints are all that is required to completely take out a runway as far as BMS is concerned. It also has the added bonus of allowing a completely stand off/ranged attack.
True, but there’s just more fun screaming over the runway at 500-600knots at 500ft compared to dropping GBUs from 20,000ft

What do you mean, Dee-Jay?

I’ve seen this pic before! Aside from the axis being defended, what other reason for dropping like this?

Icarus, thanks for the pics and confirming that it can still be done “the old way” with just a little more altitude. Might be a bit odd having to fly over an enemy airbase at 1,000-1,500ft… feels too exposed. But then again it could be remedied by a little more speed, I guess. More experimenting and practice to do! And yes, the pylons kinda start protesting past 500 knots.

I too feel more comfortable at 4-500 feet at 500kts with lots of countermeasures using manual release. I don’t like golden BB’s!

… That it is not made to drop bombs all along a 9000’ runway on the axis (which is also tactically not good).

This is why:
- BLU107 are no longer used.
- In the past when BLU107 (and BAP100) was used, attack doctrine was to be not aligned with runway axis and to perform the pass with 20° - 60° offset with several aircratfs and different DMPIs.
My advises.
- Drop bombs in PAIR. with a small interval (around 50ft - 100ft max)
- Do not attack on RWY axis but under 20 to 40°.
- Better aim intersection of RWY and taxiway.
- Altitude should be enough to allow chute deployment and rocket ignition. (Around 1500ft AAL)
- Remember to set a compatible arming delay and fuze.
- Concentrate on one section per a/c.

Try setting up PROF 1 and 2 as 500’, RP 1 and RP 9 respectively and watch the CCIP pipper jump up and down as you swap between the profiles when flying in Durandal release territory. The pipper should jump 2000’ ahead (shorter PBIL) for RP 9 compared to RP 1 because it’s showing center stick.
Also maybe post #3 is invisible to other users but I swear I covered the “how to do it like real” well enough.

Probably to saw across the entire width of the runway and to hit taxi entry points like in the picture. Say you bombed down the axis of the runway but those tough soviet planes could still use the edges… Just speculating.
I’ve also been told f-16’s would not go on combat missions without 2x wing bags. 12 BLU’s would cause an extreme amount of drag -

Meh. You shouldn’t be basing all of your knowledge of tactical use of an aircraft on a retired maintainer. Especially when we have some real combat drivers in the neighborhood. By no means am I the oracle of all things tactical.

True enough. As long as there aren’t strategically placed MANPADs it was always fun to be jinking around after the run dropping chaff/flare and looking over your shoulder to see your handiwork.

Yeah me I would feel like I was way too far above the runway for such an attack.

Yup I thought of this late last night and it makes perfect sense. Always love learning something new to put into the tool box.
