Extended-range precision artillery hits targets from 36 kilometers

Also WE know how mutch explosive the BER Version for 127 (13kg) and 155mm (7,5kg) have. If we have a diagram about how mutch the guidance takes of Volume we could guess how mutch there is.

So the 127mm contains more explosive than the 155mm? Must be a longer projectile I guess.

Ah yes, 1.5m long for 127mm vs 0.95m for 155mm, and also 40kg vs 36kg all up respectively.

Yeah. But thats only for BER but i think thats whats needed. Maybe a Future Variant of the 155mm Version If longer (probaly a limitation because of PzH 2k autoloader)
 
The whole point of adding electronics to a shell is to cut down the number of rounds necessary to perform a mission. When the Ukraine conflict began the Russian goal was quantity over accuracy. Russia was trying to deny movement and soften up targets for ground troops, requiring many rounds over time. Dumb shells were the shells of choice. The defender on the other hand could not match quantity and needed to make the most of each shot, therefore precision rounds were preferable. Shoot and move. Attrition favors the side with a non-existent to sustainable attrition rate. The results have been high on both sides initially, but have largely been mitigated with technology on the Ukraine side. Russia just keeps pouring resources in and it has taken a predictable toll.

There's reasons you want both lots of cheap dumb shells and some super precise shells. Which is what made the US Precision Guidance Kit so valuable, as it could turn any deep fuzed 155mm shell into a precision round. Not quite as accurate as an Excalibur, but good enough most of the time.

Agree, there's nothing on range or much else. Can only really assume longer range than existing PGK and better immunity to jamming.

That's because PGK is just a screw-in fuze, so its range is highly dependent on the range of the shell it is attached to. This version can work at longer ranges than the old one, but it isn't adding range to the shell by itself.
 
Any link to the source where it says GMLRS was withdrawn? I'm still seeing videos even today.

It seems hard to believe. All the 127mm are 66 cm (more or less), a 155mm like the M110/A1/A2 is 68.

The dart seems to extend well back into the body of the cartridge in the case of the 127mm though.
 
As I understand it BAE hypervelocity projectile family in which the XM1155-SC is part of, is neither ramjet or rocket assisted, so how did it achieve similar range to the Boeing/nammo shell?

Subcaliber with an optimised aerydynamic design.

Eyeah the XM1155sc.

That was just shot this past... February Irc, and broke the 110 km range mark.

Then this past October you had the Ramjet 155 breaking 100km from a M777.

Fun things been happening in the Arty world

I knew there were several long-range development items, just nothing deemed ready to field as such.

Lots of these design are still in the test phase.

But it the section of testing were Real Life Data from Combat be...

Priceless basically.

Like what going on in ukraine you can not properly simulate by any other way then doing it.

So any feed back even if its basically two lines of complaint be worth more then shooting a dozen on a close clean range.

Cause real life is not a close clean range.

It's a good place to iron-out the guidance and jam-resistance aspects as well as the implications of field use, i.e. dirt.

It's why the only testing done on the GLSDB was basic safety. Making sure they wouldn't blow up in the launcher and then getting live combat data is every ordnance engineer's dream.

Result: needs better GPS-degraded performance. Needs much better GPS-degraded performance.
 
I'm surprised they can make more accurate inertial guidance for these short-range munition these days when you look at the claimed accuracy of AIRS 40 years ago. Sure that was prohibitively expensive, but a short-range munition INS doesn't need anything like that level of accuracy to land within 10m from 100-150km away and then you'll be completely immune to jamming.
