Another factor, electric primers. My cousin told me when they needed to load a Phalanx, all radios and radars were shut off; they could detonate primers if radiating.

This sounds to me like a serious shortcoming and design flaw.

EM hazards are a known thing. It’s called HERO.

Phalanx ammo is electrically primed, just like most (all?) aviation gun systems.

So is the ammo for the 120 mm smoothbore... but tanks do not have to turn off their radios.
There also was no concern with close by radar from SPAA.
Aircraft don't switch off systems when they are carrying ammo for guns.

So from my point of view there are two possibilities. Either the safety meansures are way to cautios and interfere with the sensible operation of the system or the ammo for Phalanx is more sensitive than others and this would be a flaw.

Another fairly rare Javelin video. Interestingly the operators are using CZ Bren 2's with LPVO's.

A couple of points about primers:

Not all aircraft guns use electric priming: the GAU-12/U (AV-8B) and GAU-22/A (F-35) fire NATO 25 x 137 ammo which uses percussion priming. The GAU-8/A (A-10 aircraft and Goalkeeper CIWS) uses percussion-primed 30 x 173 NATO.

The US has developed a percussion-primed version of the M230 Chain Gun for naval use (30 x 113B ammo), but I don't think it has any takers so far.

Interestingly, Nexter makes two versions of the 30M550 series cannon in 30 x 113B, differing in the characteristics of the electric priming (one being relatively insensitive, intended mainly for use by naval aircraft). The 30M791 (30 x 150B in Rafale) also has the insensitive priming.

Yes, the USN does take precautions in handling the electric-primed 20 x 102 ammo for the Phalanx system. When it is in the magazine, the base of the ammo, containing the primer, is protected from electrical interference.

Take it with a grain of salt with all the propaganda being published. So it was either Russians shelling themselves while in Bucha or Ukrainians shelling the Russians while they occupied in Bucha? Which sounds more likely? Both sides are using more or less the same artillery types and ordanance.

But even more amusing is a claim in another article that says flechettes are practically unseen in modern conflict.
