quote from linky...............

The 25mm round actually has two warheads that provide more explosive than the current 40mm grenade launcher
????WTF???????????????????

ok. now how the feck do you pack-in more explosive in a LOT smaller dia???
it cant all be extra length.

I was always told size doesn't matter ;)

but they could be using differrent explosives

$25k? versus how much for a javelin?

No contest in terms of price.

kryptonite or unobtainium based hi-ex?

I think they are allready filling rounds with the most lethal (and safe) stuff they can.

Smaller fuse wasn't the fuse for the 40mm ammo quite large compared to the payload?

Plus they may be comparing with a 40mm HEDP, which has a copper liner and a large void, both of which cut down on explosive content.

The septics have never really explained how a grenade the size of a large marble will be more effective than a 40mm. They claim that it has better accuracy than a UGL, but it seems likely that you would have to hit the target almost smack on for it to have any effect. It's just plain old RDX inside and 'ye cannae change the laws of physics'.

Plus you still have to carry your Individual Weapon as well - I really can't see it being too popular.

Won't be long till it's mounted on vehicles.

Wonder if you can get it on a shotgun licence...

I'm trying to get my head round one or two of the sentences in the report...

It seems its big advantage is that it operates by exploding at the required distance along its trajectory. You don't aim at your target (other than for ranging), but just above them. If it's always assumed that the baddies are below the round, then the round could be made to split (i.e. the two warhead comment) and rain its lethality downwards. By doing this, could it be that in one direction it has more nastiness than the 40mm?

The weight is a bit of an issue, you wouldn't want to carry one of those as well as a rifle - and without a rifle, you'd be the weakest link in a close quarter scuffle - but it could lead to some changes in patrolling. I'm thinking of a two part patrol where the rear part is armed with a few of these things and overwatches the front part of the patrol. Or maybe they'd only be really used as an alternative armament by the top cover... The tactics may take a bit of thinking about, but I reckon it's got a future.

What - like GMG? GMG has a bigger bang, more rounds, longer range - why on earth would you want something with less capability?

I think there is a comment in there from a current US 10th Mountain Sgt who quotes that he'd be happy to carry it in addition to his M4?

The 25mm grenade is centrally fuzed - i.e. the fragments burst both forward and backwards in an hourglass pattern. The airburst fuze times it so that it goes off over the target and in theory, either end of the pattern will catch the target.

40mm on the other hand is either nose or base fuzed and is ground burst only. But the grenade is the size of a golf ball and so has a good deal more oomph to it.

I have seen marketing videos for the project where 'target effect' for 25mm was demonstrated by bursting balloons. I'm not convinced!

Current 40mm is designed for defeating armour and has a shaped charge, it also has a mechanical impact fuze with takes up a lot of room...

I am speculating that the 25mm is an optimised frag warhead using electronic fuzing and is designed to airburst based on accurate laser rangefinding from the launcher.

The lethality may therefore be better for a smaller mass..

.. "kicks another lump of sh1t" ...

The picture is a bit big, but judge for yourself. The XM-25 round is on the left. Yes, it's an electronic time fuze.
