John Kettler Posted November 22, 2016 Share Posted November 22, 2016 (edited) Pericles, Appreciate your sharing this.Perhaps the investigation could be called (not shouting) BROKEN SWORD or somesuch?! In any event, it sounds as though someone's shell case manufacturing and associated QC sucks. Also, if the Wiki's to be trusted, the article overstates the per round cost by a factor of two. Is it possible the reporter cited the price for the drastically improved new Excalibur, rather than the early stuff the Canadians and US Army have in quantity? As for the missing rounds, bet someone's celebrating after that particular acquisition!

c3k Posted November 22, 2016 Share Posted November 22, 2016 I'd call it "premature fragmentation". Embarrassing, or worse, to anyone handling the big gun. But...have any actually failed? X-raying the entire inventory? Perhaps they'll use airport screening machines during lull periods. 0 Quote Link to comment Share on other sites More sharing options...

I know X-rays are a common way of inspecting welds for cracks, along with dye penetration. As far as I know, it's sometimes used on castings, too. It has the advantage of high throughput, so I imagine X-ray inspection is probably the fastest way to look through the entire inventory. With that said, it does seem a little overkill to look over the entire inventory unless there was no pattern in the cracked shells to narrow it down. Even then, perhaps before going crazy, inspect a random sampling of the various lots? Maybe the airports are having slow days! 0 Quote Link to comment Share on other sites More sharing options...

It being the Army, they will insist on having their own, fully mil-spec of course. Michael 0 Quote Link to comment Share on other sites More sharing options...
