Az23 fuze help
I have a az 23 fuze . I am confused about what type of shell it went with. Some sources say 75mm, 88m and 105mm and higher. While othes say it wasn't used on 88mm's .My question is , was the az 23 used on 88's . I have seen a small version of a az 23 which could be mixed up with the bigger az 23 if thats the case.
It definitely was a multipurpose fuse made in large quantities. I know they were used for 88mm and higher for sure. I'm not sure of the 75mm as the warheads are somewhat a bit rare here in the US.
There are various types of AZ23, which was a nose percussion fuze for HE shells. Those used with 88mm were often marked AZ23/28. AZ23s were also used for the 75mm HE - I have one in my collection.
Clearly visible in your photo is the screw-head for adjusting the delayed-action setting ; from 'superquick' ( OV = Ohne Versoegerung ) to 'delay' ( MV = mit Versoegurung ). These equated to instantaneous or a delay of 0.11 second.
There were essentially 3 different types of fuses for the 88. Zt. Z. S/30 spring wound timed fuse (30 second), Zt Z. S/30 Fg inertia operated fuse (30 second) and finally yours the AZ 23/28. The first two were used mostly in the anti aircraft role and could be quickly calibrated by the fire control unit using a fuse setter which could cut the fuse to the desired time. I believe the AT round had a base detonation fuse of some sort with a 0 sec delay. Maybe Martin can elaborate more on that one?
That's right. The AP shells have a BdZ or Bodenzunder - base fuze. This is armed by the rotation of the shell and initiated on impact. There is a fractional delay in order to explode the shell immediately it has penetrated the armour plate.
( BTW, there's an informative section on all these fuzes as well as the shells themselves in the US War Department's Technical Manual of 88MM Antiaircraft Gun Materiel from 29 June 1943, which I believe may be available as a reprint ).
is there explosives inside? They are very dangerous..
Gee this really is an old thread of mine hahahah.
Nah mate there is no explosives inside. All my ordnance is inert
By the way: Zt. Z. S/30 were still used until the 70ties on 100mm French navy inert/drill shells.
