Deployable 'electromagnetic railgun'

Since it melts the projectile and shoots out a spray of molten bits, it's more of a short-range flamethrower.

Smaller Railguns

The high cost of advanced ballistics is driving the military toward cheaper alternatives like direct energy and electromagnetic railgun that hurl shells at hypersonic speeds. The Navy is planning an at-sea demonstration of a BAE designed railgun that can hurl 44-pound shells.

But Carter wants to shrink railgun technology until it can fit into “the five-inch guns at the front of every Navy destroyer, and also the hundreds of Army Paladin self-propelled howitzers. This way, instead of spending more money on more expensive interceptors, we can turn past offense into future defense – defeating incoming missile raids at much lower cost per round, and thereby imposing higher costs on the attacker,” he said.

He noted a January demonstration that equipped a Paladin with railgun capabilities.

From Military.com - "In fact, we tested the first shots of the hypervelocity projectile out of a Paladin a little over a month ago, and we found that it also significantly increases the range," Carter said

If you're at Paladin are you close to Abrams?

I think this misunderstands what the test was about. The Navy's Hypervelocity Projectile is intended to usable from railguns and also from conventional 127mm and 155mm guns by changing the sabot but using the same flight body. I believe the test referenced here is a launch of the HVP from a conventional 155mm gun. It will still be faster than a standard shell, roughly Mach 3 (versus 2.4 for a conventional shell) and range is significantly longer due to reduced drag, but this is not an electromagnetic railgun test.

And here's an article about Carter's speech that better explains the distinction:

Yeah secretary Carter is not the only one to make this mistake, Rear Admiral Fanta was talking about it recently and mistakenly said that the HVP fired from the Mk45 could match the range/speed of a Railgun. That said, the point about the benefits of sharing the HVP across multiple guns in multiple services is well made.

Something to consider is that some of those Projectile Tracking System radars for monitoring outbound artillery rounds can provide a weapons quality track of inbound threats as well.

Thank you Tom,
you are most gracious in assuring proper explanation.
