M734 Multi-Option Fuze
I'm wondering if maybe US (and others that use them) mortars might rate an increase to their lethality (HE Kill) based on the widespread use of the M734 Multi-Option Fuze since the mid 80's?
It's a rangefinder and collision detection system used on 60mm, 81mm, and 120mm mortar shells as a trigger to detonate the shells at height (i.e. ye old VT for mortars). |
Re: M734 Multi-Option Fuze
......I'll let everyone debate this then see what the result is
ALL 8x mm mortars in the game right now are HEK 11 so if we move say.... the M252 to 12 or 13 then what needs to be done is find out who else uses a fuse system like that and if it's justified to move 81mm mortars into the 90mm - 100mm kill range and if we want to avoid that then we are left with moving them to HEK 12 and I sincerely doubt a 1 HEK change will make any noticeable change to game play. Now..... if there is some proof this fusing system makes 81mm ( or 60mm or 120mm ) mortars as effective as a larger calibre then there is justification to make a change but we should see that proof So I'm not saying no, I'm just not saying yes Don |

Yeah, +1 would be pointless, is +2 "too much" and "reasonable"? Currently the 155mm goes from 21 HE Kill to 42 HE Kill for the VT version, which may be a bit much perhaps. I'm thinking a 25% increase maybe. So 60mm from 7 to 9, 81mm from 11 to 13-14, 120mm from 19 to 23-24, the 155mm VT from 42 to 26. Discussion? |
Re: M734 Multi-Option Fuze
If we compare the +25% rule to AMOS and STRIX I get the feeling that it's too high. Neither AMOS nor STRIX currently get any additional HEK bonus.
Swedish OOB (obat66, v. 5.5) 120mm AMOS ACC: 6 HEK: 19 120mm STRIX ACC: 10 HEK: 19 120mm Mortar ACC: 3 HEK: 19 81mm Mortar Acc: 3 HEK: 11 The fact that AMOS and STRIX rounds can be fired to hit simultaneously does not IMO seem to be reflected in the OOB. +2 might be reasonable for intelligent munitions all around with maybe some additional bonuses for big calibers. How about for every additional 10 HEK units (without VT) there's a +2 bonus with VT munitions? Howitzers etc., typical HEK (base) for mm, proposed addition, new HEK for VT and similar improved munitions Code:
mm base add hek Mortars, typical HEK (base) for mm, proposed addition, new HEK for VT and similar improved munitions Code:
mm base add hek |
Re: M734 Multi-Option Fuze
As it stands now all weapons across all OOBs have the same HE Kill from 1946 to 2020 based strictly on caliber (with a handful of exceptions like the US 155mm VT and cluster munitions).
One could (eventually) find out when each nation got access to sufficient VT type fuses to make an across-the-board improvement to that nations mortar/artillery effectiveness. And just because Russia gets this increase in say (and this is merely a number for the sake of discussion) 1990 doesn't mean the Mujahadeen who use Russian weapons will ever have a significant number of such fuses before 2020. What is a "significant number"? I'd say 50%+ of actually used ammunition. Having 10,000 in inventory that are only actually used on special occasions wouldn't count. Yeah, this IS a can-of-worms that may well be more trouble then it's worth to Don and Andy. Thus the reason for this thread. How much increase? What nations should get it? When? Just make an across-the-board increase at some date based on the more common availability of such things post 1970ish? For the US we can definitely identify the availability of the M734 Fuze for mortars as "justification" for when. Can we DEFINITELY identify something similar for other nations or are we just making (hopefully) educated guesses? |
Re: M734 Multi-Option Fuze
I remember reading a study on the effect on proxy fuzes a long time ago. IIRC the increase in lethality, compared to contact fuzes, varies widely depending on target disposition. The greatest increase,by some ludicrous high percentange, was against troops laying behind vertical cover but without overhead protection. The smallest was against troops standing in the open, though still in the double digit range; in any case it is not how you want be caught by an artillery strike.

Re: M734 Multi-Option Fuze
Saw VT demonstrated at RA Larkhill open day as a cadet back in the 70s.
It was (deliberately) fired over a bit of the landscape where the topsoil had been removed. Since Salisbury Plain is chalky (it's a pig to dig in there), it was quite impressive watching the white stuff go puff... Yes, against unprotected troops or trenches with no overhead cover, very nasty. Made me REALLY appreciate why stage 2 top cover (18 inches of soil or sandbag on top of some wood) cover AFAIR was considered so absolutely necessary when we did digging-in exercises. SP does not differentiate between stage 1 open topped entrenchments and stage 2 (L-shaped covered shelter bay) and further (bunkering up, basically)stages. Andy |
Re: M734 Multi-Option Fuze
Had to "dumb this down a little" so I found this article which I hope will help others on the various types of mortar fuzes out there, some background, how they work, what applications they're designed for and where the tech is going (Some already here now, article was written in 2004.). If you click on the authors name you'll find other articles he's written and a further search revealed he's also written many books on military avaition matters as well. Free Library is not a "WIKI" type site.
http://www.thefreelibrary.com/Fuzes+...s.-a0122105138 http://www.globalsecurity.org/milita...ef2.htm#fm7_10 This second ref. was most helpful in a discussion IMP started on dare I say it...maybe in a different way "Charlie Mike". Not to worry not going there again!?! Be careful Global Security doesn't want to be free anymore so you'll only get 7 visits per month free now otherwise it's 9.95 per, the dirty rotten...basses, and make sure you descale them good before cooking!?! Interesting research project all this though. Regards, Pat |
Re: M734 Multi-Option Fuze
That list of manufacturers in the first article is VERY useful.
As are the comments in the article about actual usage. |
Re: M734 Multi-Option Fuze
Last of fundamentals I promise, but goes beyond that as well. This will be most useful for newer and maybe not so new players as I think the game does a decent job with arty as a whole generally which is why this might be again useful for players especially the tables shown. This is taken from the USA FM 23-91 Chapter 2 Fundamentals of Mortar Gunnery.

Just saw your post as mine went up; check the following two websites I use for other purposes, but they both have an extensive company listing that might help all in the heart of this matter never mind...here http://www.army-guide.com/eng/firms.php http://www.army-technology.com/contractors/ammunition/ http://www.army-technology.com/contr...indexAtoZ.html Night Owls; somebody should put us out of our misery!?!
