Presumably, the multi rails were all fuse set well prior to the engagement (proximity fuses in later models?) whereas the 2 rails had a body each to and could be fuse set and loaded in response to commands from the prediction set up.

It`seems to have been a two man job to set the fuze: IWM H 021133

Tehre was a desire and belief that they'd have proximity fuse ready. Which made it vastly simpler to do. No idea how well that went. I think some one up thread was talking about a photo receptive fuse.

I'm not aware of a radar type proximity fuze being used on UP rockets. There were attempts to make photocell type fuzes, but they never got past the trials stage. I think they were all time fuzed using El Cheapo burning fuzes. I would imagine the multi launch setups were all pre-fused to create a standard box barrage at various set heights, and you basically wait for a suitable bomber stream to fly at the selected height!

The radar type VT fuzes used on 3.7 and artillery natures needed to be spun to arm the fuze and energise the power pack. The 3" UP did not spin! (UP = "Unrotated Projectile")

I suppose you could coax a bit of nuance out of the timimg by engaging at longer ranges?

Did the V1s come in at a consistent altitude?

Yes,

They had an auto altimeter that kept them at a set altitude until the range gear cut in and the bomb dived.

But were they set at significantly different altitudes to confuse defences?

I think it probably didn't matter in the case of V1s as they did't vary course either. If they travelled over AAA they didn't do anything to defeat the prediction so the guns or rockets could be layed on without any interruption.
 
Some light viewing for the casual reader...


Z Battery fire seems to be form of predicted concentration.

Now there's a find... I wonder if we can confirm it?

Apparently the Admiralty requested PAC for defence of aircraft carriers. Now, did it happen? I'm guessing its going to be an escort carrier, not a full fat carrier.

Edit:
Apparently it was Carriers in the Med, date of early 41.
