The findings come from a newly released Marine Corps report that’s over 600 pages long.
That report determined that the mishap was the result of a malfunction in the artillery’s fuze, which electronically controls the timing of detonation.
“The M767Al fuze is extremely reliable, with only one malfunction in its service history, in 2017, that was ultimately determined to be caused by an external factor,” the report said. “It is manufactured to a tolerance of one defect in a million.”
...
The report ruled out wrongdoing by Marines, interference by other unmanned aerial systems and birds.
Instead, the report suggested that several typically harmless conditions may have aligned in a way that changed the likelihood of a malfunction.
According to the Marine Corps, these factors could have been the close proximity of weapons to each other, blast overpressure and the potential presence of an electromagnetic charge.

According to the Marine Corps report, that metal fragment was about 2 inches long and half an inch wide and left a small dent and scratch on the hood of the vehicle.
After the incident, CHP notified the Marine Corps, which then canceled additional live-fire exercises.

When I was helping the IDF recycle fire base garbage, I found a 50mm ammo box with 8 of these in it in the dump pile.
Worth $2k each.
Accurate to 1/10th of a second, iirc.

Sent it back to the front lines for use.
Note: It was not a 155mm artillery shell explosion, only the fuse of a 155mm artillery shell. One has about 15 lbs of TNT, the other a “booster” pellet to initiate the explosion of the main charge.
The booster pellet is much less than an ounce, I believe.
Perhaps someone else can give the exact weight of the booste pellet.
It is the difference between a primer and the main charge in a rifle cartridge.
Report here:
Some redactions due to FOIA exemptions but still interesting.
It’s always that “one time” that gets you.
The Army hit a ranch near Fort Hood with a barrage of 155 a few years ago, damaging a house and other property. In another incident they hit an occupied building on base.
But shooting over an interstate sounds like a very bad idea.
But I imagine the Safety Officer, gun crew, gun platoon commander. CO and Gummy were all sh*tting bricks until that report exonerating them was issued.
According to the marines, it was a full-on shellburst.
Kinda hard for the shell not to off if the fuze does.
However, no harm, no foul. Very little harm in this case. We probably learned something worth while.

I recall one thast ended up (a dud, if I remember right) in the parking lot of a Walmart a few years ago.
Mm-hm.
Are they firing shells over the freeway?
Good, but s*** happens!
From that part of the story I figured the Marines returned fire....

The freeway was closed at the time of the shell fuse malfunction (hence the presence of parked CHP vehicles)(Pendleton property is on both sides of the freeway..they use the beach for exercises). It was closed for a “live fire” demonstration for J.D. Vance & Hegseth as part of the Marine Corps 250th celebration. The incident caused quite a stir among CA democrats of course:
