What are the bomb fusing times?

[Gunfreak]

They've added fusing on the ww2 bombs. But not the ability to set them yourself. Anyone have a list of the default fusing times on the bombs the mossie carries?

[DD_Fenrir]

What seems to be the case at this point:

500lb SAP - Confirmed instantaneous.

500lb MC Mk II - Confirmed instantaneous.

500lb MC Short Tail - Confirmed instantaneous.

500lb GP Mk.IV - Confirmed instantaneous.

500lb GP Mk.V - ED documentation says 30 min delay fuse.

500lb GP Short Tail - Confirmed instantaneous.

So the fusing isn't really useful yet for low level bombing in the mossies unless you wanna hang around for 30 minutes.

[DD_Fenrir]

Indeed. Bear in mind this is an iterative implementation; from the Discord the various fusing options are programmed in the coding but they ran out of time to finalise the GUI changes necessary to allow us to access them. They’ll come in due course.

The mk V bomb uses a no 17 pistol which has delay times of a minimum 30 mins, up to a max of 36 hrs. delay.

 

It is a "one off" bomb, specially made to use up a stock of old obsolete long fuses and cannot be used with anything else.

[Bozon]

That is perfect. In 30 min you have time to RTB, get a new plane, and come back to see your bombs explode…

In MP what is most likely to happen is that by the time your delayed bombs finally detonate, the target will already be destroyed by someone with instantaneous fuses.

I have updated the 2nd post after doing some testing.

So what about the Mk V, probably the most useless bomb in simulator history, if simulated correctly.

ROFL......nothing to get exited here then,so we've got one bomb a 500lb GP Mk.V - ED documentation with a  30 min delay fuse,going back to sleep,wake me up when there's a serious change to the timings,until then zzzzz.

currently, the only bomb with an acceptable delayed fusing so you can do a low level bomb run is on the Axis side, specifically a 500kg J bomb, it has either a 5 or 8 second delay and is .. awesome..

The Bomb Mk V was manufactured to use up existing stocks of the Pistol No. 17 (long delay), which is too long to fit in the Bomb Mk IV.

Mk V—Tail pistol No. 17 (Long Delay) only

DELAY TIMES

1/2 hour to 36 hours.

We only gave a 1/2 hour option as longer seems too extreme for most situations. 

(we may add more options for game play later, but right now its correct as is)

OK. So lets try out the No 17 pistol.

It has a tamper proof mechanism, so I hope nobody tries to disarm it, while I wait for half hour for it to go bang.

But think how fun it could be to seed an enemy runway with those

As I said I want to add another option to it, and I think I have something to add, but we are trying to be as real as possible with as much gameplay options, you can use the Mk IV and have more options 

[Holbeach]

Ok. A spectacular result.

I dropped 2 Mk V at Hornchurch, then landed and watched the 2 small craters with the speakers turned up.

This became quite nerve racking, with the 30 min time approaching.

By chance, the Red Arrows display team flew low over my house, with an enormous racket, which included my dog barking and my wife shouting.

With my attention diverted, the 2 bombs went off and I nearly <profanity> myself.

When granny visits on Sunday, I will place her chair near the pc and see what happens.

Is there any reason the 500lb Mk V is missing off the bomb bay option.

Is this intentional?

They are too long you need the short tail in there.

The 500lb Mk V short tail was made for the Mosquito bomb bay and is about half inch shorter than the 250lb long tail and the same overall size as the Mk IV GP.

The Mk V body is actually slightly shorter than the Mk IV.

The 500lb Mk V short tail with MK 17 pistol, will fit in the bomb bay.

A couple of things I noticed while trying these out, that you might like to look into.

Nose pistols don't use timed detonators and are always instantaneous (RAF). Timing is taken care of by the tail pistol/detonators.

The MC 500lb is a Mk VI (3 lug), not a MkII (1 lug obsolete).

The Mk V is a denial bomb, dropped on factories, airfields etc. so there are possibilities for missions.

They would be dropped by post raid recce aircraft in order to hamper the repair work, with the 30 min to 36 hour tamper-proof timers and during the raid itself.

The Mk IV can be fitted with a timer up to 144 hours, but that might be pushing it a bit.

The Mk IV has timings quoted for the Mk 28 tail pistol detonators.

The mk 30 pistol, as fitted, use the much more useful detonator timings of:-

Zero, 0.025, 0.04, 0.05, 0.14, 0.5, 1, 2, 3, 11, and 25 to 30 secs. delay.

These contain more useful low level delays and are correct for the pistol installed.

I was looking for 3 second fuse. But none of the bombs have it. 1 second might to to short to avoid splash damage from low level drop. And 11 seems in excess(given AI reaction time. I assume if you drop and 11 second bomb on a mobile target like a vehicle column. The vehicles will scatter before the bomb goes off.

Is what it is mate; these are the actual, prototypical fuse times as used by the RAF in WW2.

Bear in mind that in reality low level bomb releases were far more likely to result in bombs skipping:

 

1 or even 3 seconds could not guarantee you being clear of your own bomb blast if the bombs travelled significantly after dropping.

The RAF didn't come up with the 11 second fuse by plucking a number out of thin air; these timings would have come after much testing and include a safety factor to make absolutely certain you wouldn't get fragged by your own bomb detonation.

As for mobile targets, this isn't where you'd use skip bombing; skip bombing was used against shipping and for static precision targets for the very reasons you outline. Mobile vehicle targets are best attacked by dive or glide bombing profiles with pull out at sufficient altitude to mitigate any danger of being caught by the blast of your own bombs.

Zero, 0.025, 0.04, 0.05, 0.14, 0.5, 1, 2, 3, 11, and 25 to 30 secs. delay.

These real life timings for the Mk 30 tail pistol were:-

0.025, 0.04, 0.05, 0.14, 0.5. Penetration of buildings etc before exploding.

1, 2, 3 secs. Low level static or moving targets.

11 and (25/30 secs, ( added 1944)), were to protect following low aircraft on the same run, e.g. Amiens Prison.

In game we have 0, 0,12, 1, 11, secs. (no 28 pistol which we don't have).

I tried the 1 sec detonator at 290 mph with 4 500lb MC, dropped from 20' AGL, with no ill effect.

 

For skip bombing at a lower alt than this a completely new pistol was made, which would trigger on side impact.

290mph is about 130 meters a second. So mabye half a second for the drop. You'll get about 200 meters away from the bomb before it blows up. That's probably not within safety limits in real life. But I guess it works in DCS.
