A bunker-busting shell that gets so hot on impact that it burns its way through concrete and steel is being developed by the US Navy's Warfare Center in Virginia.

The shell contains a mixture of aluminium polytetrafluoroethylene (PTFE) and perchlorate oxydiser, moulded together into an aerodynamic shape. To prevent the mixture from disintegrating as it travels through air at high velocity the shell is wrapped in a soft Teflon tape, which is wound tight under high tension, heated and topped with epoxy glue to prevent unravelling.

Its high-velocity impact acts as a catalyst, forcing the two chemicals together in a red hot reaction. The projectile gets so hot so fast that it should instantly burn its way through armour plating or other defences.

And the burning shell would avoid the environmental pitfalls of radioactive depleted uranium - currently the most common material used in armour-piercing shells.

I wonder if they would make good bunker busters? Burn through the ground and then through concrete.

It sounds like it could work well. Can they somehow put an explosive inside the round? Would just burning a hole into a bunker do much damage without an explosion or fireball? If they can somehow get an explosive charge inside the round that won't detonate from the casing burning it could be really lethal. Do you think they could use the burning part as a way to deliver an explosive?

put an explosive in it? if the cap was metal it would then basically act like a shaped charge..in fact it is sort of acting like a shaped charge, but instead of using holt molten metal to makea jet through its kinda...turnings itself in to er..molten metal to burn though?

I went to the marines a few years ago and the showed me a piece of weaponry
against armored vehicles and/or tanks, it was really small and you had to plant
it next to the road and put a line to the other side of the road, when a hostile
vehicle passed it something really hot just penetrated the vehicle melting
everything and everybody inside. They also told me that if it missed, you had to
walk about 2 km before you would find the thing to use it again.

I understand that it would create a jet of molten metal when used against armor, but what about concrete in the bunker busting role?

This is from the article

"A bunker-busting shell that gets so hot on impact that it burns its way through concrete and steel is being developed by the US Navy's Warfare Center in Virginia."

When I was talking about putting an explosive in it I meant when used against concrete. Could this create a jet of molten concrete?? Bunkers are much bigger than armored vehicles so I don't think burning a hole into one or even spraying molten anything would be as devastating compared to an armored vehicle. I hope that makes sense.

I don;t think this is correct. As I read it this is essentially an incendiary/explosive device triggered by impact; the patent does not mention penetration effects. The high temperature will not aid penetration - think for a moment about the time required for heat transfer.
New Sci are normally excellent but Barry Fox is not a specialist in this area
