bobbymike said:Work: New hypervelocity gun could displace rail gun in next administration
Deputy Defense Secretary Bob Work said Monday that current Pentagon leaders have made investments intended to position the next presidential administration to offset expected Russian and Chinese technological advancements, specifically lessons learned about a new hypervelocity gun.
TomS said:This is the same thing we've talked about before -- the Navy's Hypervelocity Projectile is compatible with both conventional propellant guns and railguns, with the conventional gun offering about half the range for the same flight body.
Moose said:Yeah, I'm not a subscriber but this is likely a reporter not understanding the HVP's cross-compatibility with conventional+AGS systems rather than the Navy moving away from railgun.

As an example, he pointed to the idea of a electromagnetic railgun. Initially, Work and his team thought that was an area that would be a major focus of development, but as they experimented they realized that a powder gun with a hypervelocity round could have almost the same impact — but at a fraction of the cost, because it did not require the development, testing and adaptation of a new gun.
“We’re going to say ‘look, this is the place where [we think] you want to put your money,’ but we’re going to have enough money in both the electromagnetic railgun and the powder gun that if the new administration says ‘I really want the electromagnetic railgun, this is the way I want to go,’ knock yourself out,” Work said. “We’ve set you up for success.”
TomS said:But I'm not sold. Railgun brings twice the range (four times the covered area) and more terminal impact. It's going to take a pile of cash up front to develop them, but the long-term impact is going to be too important to drop now.
some amount of money has been spent on scramshells and Electro-thermal chemical guns and even liquid guns and where are they..sferrin said:TomS said:But I'm not sold.

Wouldn't be the first time the US has foolishly tossed away technology only to have to reinvent it later. Ramjet/scramjets and BGVs come to mind. They've currently retreated to their safe space and are licking their wounds with no signs of ever leaving it. Russia and China don't seem to be deterred by learning experiences.

Especially since the USN said, essentially, they don't want to waste the time testing a railgun on a test ship but would instead prefer to mount it on a Zumwalt and do it all there.

And yet, there's a railgun sitting on USNS Trenton right now waiting for testing this summer.

Whoever pays for it owns it. Has BAE and GA been funding these railguns on their own dime?
how much for a final integration cost for a compact, efficient, tactical rugged system? meanwhile already paid for various propellant tech both multiple competing private and USG research (decades old combined emerging material science) would deliver far greater range.. as always EM may be good for high RPM point defense.marauder2048 said:sferrin said:jsport said:Any cursory look at the two prototypes displays quite clearly display the complexity requiring reduction (and "reduction to practice" and who pays for those intellectual rights?) as well as where energy "loss" is introduced throughout.

Both BAE and GA funded their launchers with IRAD in the pre-2012 NDAA regime.
