Navy Rail Gun at it again. Yeah!

Nice pic in the release, but the Forum won't link to an .ashx file. Sorry.

Better pic:

Here is the 2008 test plan brief. ONR appears to be commencing INP Phase II.

And finally here is the photo of the gun installed at the Dahlgren test building I tried to post earlier.

Still no data released about the wear on the rails, which is the only remaining technological challenge I'm aware of. They seem to have solved the wear on the projectile itself, though we won't know until they actually try to fire the thing 110 miles.

The delivered test article from BAE is designed for 100 shot proof. The existing ONR Lab Test gun has fired over 1000 rounds. Everyone I know expects the BAE article to do well beyond the 100 mark.

General Atomics claims even better performance with the Blitzer gun. They essentially claim to have cracked the nut and are pressing for near term ship installs to replace Mk 45 5inch 54/62 mounts. They say the Pulse Former and gun are essentially ready to go and provide for improved performance over the Mk 45s. They point out that the system they have is a 'variable yield' providing for tactically relevant use from 5MJ for low angle horizon shots and dial-a-round up to 20MJ for long range indirect fires or Anti-Ballistic work.

I think GA is angling to get a fullup DEMO mount and then jump start for existing hull retros. I think they may-be can pull it off. ONR will get a crack at GA's gun right behind BAE. They are stacked for testing now. BAE is installed, and will run the program this month. GA is expected to install and run the same program in March.
