JDAM Fuses- DSU-33

[H60MTI]

Has anyone used this fuse yet? Seems like it's an airburst nose fuse. Just curious if anyone has used it and know if it's worth using on enemy planes sitting on the tarmac.

 

I also noticed there's no forum for just the weapons...Don't know if that's something the moderators could look into...

You can tell it detonates a little above the target but not enough to make it have a bigger effect. I'd just stick with a normal fuse. That's just my opinion. If you could adjust the height of the detonation, especially with all 8 GBU-32's, then you could do some damage.

It's more effective than standard fuses on infantry and soft targets like logistics trucks.

Infantry is pretty soft *evil grin*

Technically, the DSU-33 is a proximity sensor for installation in the nose fuze well of general-purpose warheads. So it is not a fuze in itself, but it is a sensor that triggers the beginning of the functional delay of the actual fuze. 

As stated before, it's particularly well designed for personal in the open and non armoured vehicles. 

More details here if you want.

can't tell the difference. The fuze setting doesn't seem to make sense yet

Basically, if you're using a DSU-33, at about 20 feet above the surface (depending on the angle of impact, type of surface, etc...), the DSU will tell your tail fuze to start the functionning delay.

Knowing that a JDAM impacts at a speed of 250 to 300 m/s or 800 to 1000 ft/s, you can then determine the height of burst (HOB) above the surface: with a delay of 0 ms, HOB at 20ft, with 10 ms, HOB around 10 ft, with 25 ms, HOB around -5 ft, etc...

Note that a negative HOB can be useful (but in very specific situations), for example if you're dropping your bomb above the forest canopy: an impact fuze won't be triggered when it reaches the treetop, but a proximity sensor certainly will be, and by knowing the height of the trees and the bomb's dive angle, you can calculate the delay required for the fuze.

Has anyone tested effectiveness vs SAM radars and launchers? Irl I imagine they would be affected quite heavily due to the unarmored nature of radar and EW equipment and the rather explosive nature of rocket fuel and missile warheads

I have tested it and have to correct one of my earlier statements. DSU-33 currently makes no difference to Impact it could even have a detrimental effect.

 

I chose a flat surface on which infantrymen were standing and then measured the radius of how many died on Impact vs DSU-33. There was basically no difference. 

The impact fuze also triggers on vehicles, so if it also triggers on an airplane, the distance to the surrounding vehicles increases and the damage is even reduced.

they definitely havent modelled the airbust effect yet at all. I don't think that will happen till whatever this fragmentation model overhaul is
