Been wondering the same, but it would not fulfil the flight time requirement?

Airtronic seems to have found a good solution with their featherweight RPG-7.

Such a weapon with clever rounds, and maybe some guided ones / smart optics, are probably good enough for a lot of situations.

Then again, other systems mentioned before have my administration - Russian (Bur, RPG-26 and GM-94) and Chinese (QLZ-87 and LG-5) systems, and their derivatives.

Probably not. It certainly couldn't put a round through a window, two stories up at 200 yards . . .

Considering that the British found the 40mm grenade launcher to be a very poor replacement for the 51mm mortar, I wonder if a 50 to 60mm mortar with a decent fire control system and the ability to launch guided munitions would be a better solution than any grenade launcher no matter how clever its sighting / fusing system is. 

A few years ago we had a 200-300 post thread on man portable HE systems. The general consensus on the 3 best bang for the buck western systems were:

-Milkor M32 w/ Medium Velocity Airburst Grenades + Fire Control Unit

-M72E11 Airburst Law + Fire Control Unit 

And then to your point

-Imortar lightweight (10lb) 60mm with Fire control unit + SAAB MAPAM 

Fire control unit:

Well that is the old soviet RPG with even the Russians make little use of any more. It is an RCL and a more accurate round is certainly possible. Rifling the tube and an expanding plastic driving band to start a slow roll that the fins maintain could be as accurate as the the CG and give much greater flexibility in warhead weight. Aimtronic got the weight to 3.5 kg.

Depends on the design parameters.  If the 84mm 441D warhead were scaled down to 66mm, it would be a lot smaller than the 66mm M72E11 warhead.

That raises another interesting question.

How large is the 84mm 441D warhead vs the M72E11?

E11 is 0.8kg HE + 4000 tungsten BB's. But I haven't found the specs for the 441D.

If it turns out the 84mm warhead is comparable in size to the 66mm LAW, then that calls into question the point of even having the CG as a HE lobber.

The reason why US troops walk so much is because they are often in 1. Vehicle unfriendly terrain, and 2. To get out and talk to the locals. This is the root of the problem of overloading of troops, and won't go away.

Sure it will, as soon as the US stops occupying countries with hostile populations.

441D fires a 5.07 lbs (2.3kg) projectile with 590g HE fill of PBXN-110, steel body containing an additional 800 steel pellets. Body splinters into fragments approximately the same size as the pellets (unknown if PFF / scored internally).  Safe to 40m, fully armed by 70m, not supposed to engage targets closer than 200m

TOF to 300m ~1.6s, to 700m 3.4s, to 1,000m 5.1s

"Max effective range" setting for airburst is 1250m, for impact is 1,300m

____


HEDP 502RS also fires a 5.07 lbs (2.3kg) projectile with 590g HE fill of PBXN-110 and steel body, not supposed to engage targets less than 150m away, has impact and delay function.

TOF to 150m ~.71s, to 300m, 1.49s, to 600m 3.36s

"Max effective range" 300m vs moving target, 500m vs stationary target, 1,000m vs exposed troops

____


ASM 509 Anti Structure Munition fires a 7.5 lbs (3.4kg)  projectile with 2,000g HE fill of PAX-47, aluminum body with enhanced blast explosive to be used against walls, bricks, concrete and LAVs. Not supposed to engage targets less than 12m(!) away (also the minimum arming distance)


TOF to 150m ~.9s, to 300m, 1.89s, to 450m 2.94s

"Max effective range" supposed to be 300m

All rounds have a limit on the number fired in a 24 hour period for crew/operator safety

441D's SAI (Safety, Aiming, and Initiation) unit has an additional 353 g or so PBXN, bringing the total HE fill to some 948 g, or about 41.2% of the shell mass. Better than the 25.7% of the HEDP 502RS but still a far cry from the 58.8% of the ASMB509!
