Astro II unguided rocket is now considered as obsolete, high
CEP, it is tactically useless at above 40km( as stated by Russian
Military scientist), just look at Hizboallah's unguided rocket
against Israel , nothing strategically impt was hit even after
thousands of rockets.
Here what I have posted earliar and you will understand the latest
trend for the new role of LR GPS guided rocket/missile
system:
My guess is if it is true that SAF is getting MLRS, it will not be
used as in traditional arty role but as a land based strategic
precision strike using LR GPS guided missiles as in US ATACMS or
Israeli EXTRA.
Read this for the future of MLRS:

Not as traditonal arty pieces especially those using unguided
rockets as even the US army has already stop buying unguided rocket
but going for LR GMLRS and ATACMS.
Here the quote:
In January 2006, the U.S. Army announced that the majority of
(possibly all?) future purchases of tactical MLRS rockets will be
M31s with unitary warhead. ( i.e. GPS guided, single warhead)

Here another quote:
The US Army is currently working on developing and fielding
unitary (one large warhead instead of submunitions) rocket and
ATACMS variants, as well as a guided rocket.
MLRS has recently been upgraded with guided rounds. Phase I testing
of a guided unitary round (XM31) was completed on an accelerated
schedule in March 2006. Due to an Urgent Need Statement the guided
unitary round has already been fielded and used in action in
Iraq.[1] Lockheed Martin also received a contract to convert
existing M30 DPICM GMLRS rockets to the XM31 unitary
variant

So from the above, US is not going for any unguided rocket like the
M26 but all single warhead GPS guided GMLRS and ATACMS, I believe
SAF is going toward the same direction.
