Capacitance based fuses became highly developed after the second
world
war due to their high resistance against jamming techniques.

It is unlikely that the shell could have been easily degraded by
jamming or chaff. (unlike the Allied shell).


What would have happened if the proximity fuse was not abandoned in
1940 but development continued such that it entered service in
1943?

The Allies would have developed specific ways of jamming the fuse -
nothing is unvulnerable.

Some things are so difficult they are not realistically viable. Laser,
Photoelectric and Capacitative proximity fuses are simply very
difficult to jam or deceive. The Allied VT was based on RF (radio
frequency) methods) and it was shown to be vulnerable to predetonation
becuase it was easy to get RF energy into the detection circuity using
a mechnically swept oscilator. Capacitence based fuses use much lower
frequencies that are effectively DC. They more or less rely on
detecting changes in 'fields'. It is very hard to radiate interfering
energy into the circuity while it is easier to introduce changes to
avoid deception. Getting sufficient range is more of a struggle with
these fuses.

Fuze jamming doesn't seem to be regarded as a very viable method today
excepting the most primitive of munitions.
