Singapore
locally design and built Primus 155mm 39 Calibre Self Propelled
Howitzer
,when unveiled in 2003,was the then lighest armoured SPH
in the world.
USA Future Combat System Non Line of Sight Cannon (FSC
NLOS-Cannon)
is still under development.see 1.
"The
initial 5 prototypes(of NLOS Cannon), delivered in calendar year
2008."
pl see 4A below.
Although they share some basic features,
NLOS-Cannon possess some unique features:
1.a multiple round simultaneous impact (MRSI)
capability,see 2 below
2. precision fires, through the XM982
Excalibur,see2
3.“The laser ignition system offers much better
precision,
rapid fire, and automation than the
mechanical method, and it’s
safer,” "Sandia proposed a new isolaion
sys."see 3.
However,according to
SATCOM 2007,only the laser ignition was
then incorporated in prototypes.Read today's afternoon
posting.
some
interesting issues
4.weight of
NLOS-cannon increase from 20 tons to 27 tons.see 4
below.
Weight continues to be a concern for both the NLOS-C and other
FCS vehicles. Original plans called for the vehicles to come in at
20 tons, which would have allowed them to be transported on C-130s.
That plan has been abandoned and most vehicles are now at 27 tons,
meaning they must now be taken on larger C-17s, which cannot land
on all runways.
Signorelli# said 27.4 tons is the absolute limit to fit three
fully loaded NLOS-Cs onto a C-17. Any more than that, and only two
would fit, thus eroding further an FCS brigade’s mobility.
#Mark Signorelli, NLOS-C program manager at lead contractor BAE
Systems.
4A.two protoypes of 24 and 27 tons
The initial 5 prototypes, delivered in calendar year 2008, will
be the 24 ton MGV
configuration as previously discussed with Congress. The 3remaining
calendar year 2009 prototypes will be updated to the 27 ton configuration allowing for more
pertinent valuable test data to be obtained which, ultimately could
reduce
final configuration prototype testing costs.

5.Is there a
high risk combing few features in a new
platoforms
----much reduced weight
---multiple round simultaneous impact (MRSI)
capability,
precision fires through the XM982 Excalibur,and
the laser ignition system?
6.Are 2 crews
enough to man the NLOS-Cannon?
In this kind of platform,i think u need one driver who engage
most of his time,
if not all,to observe and navigate the route and drive.will
another man capable
to handle the rest of the jobs,like
help to observe the situation and effects of firings
comm,receieve info and feedback,SITREP etc
input target info into Combat Sys etc etc
There are few more interesting issues:
7.Date of
fielding units(2014) and 38 calibre chosen save 1367
pounds
http://sill-www.army.mil/FAMAG/2006/MAR_APR_2006/MAR_APR_06_PAGES_10_12.pdf
Projected for fielding in 2014, the NLOS-C will give the brigade
combat team (BCT) commander unprecedented responsiveness and
lethality.
The Army and Field Artillery selected the 38-caliber tube over the longer 39-caliber
tube. The 38-caliber tube trades the 39-caliber tube’s additional four kilometers of range (using
the M549 rocket-assisted projectile) but saves 1,367 pounds. With the weight
savings, NLOS-C will be C-130-deployable with about 25 percent of
its basic load of ammunition and still will satisfy the NLOS-C
operational requirements.end of quote
8.Is it
really Multiple Round Simultaneous Impact
(MRSI)?
I think few rounds reach the target at the same time
or within few seconds then can be called as above.
Pl forgive me if my military or language not so good.
But,....
August 2005
The NLOS Cannon CTD successfully fires six, four-round Multiple
Round Simultaneous Impact (MRSI) missions. During each mission, all
rounds impacted within four seconds of each other. The missions were fired at
Zones 2 and 3 using a combination of M231 and M232 Modular
Artillery Charge System (MACS) propellants, marking the first time
a U.S. howitzer fired a MRSI mission using more than one type of
standard MACS propellant.

http://www.baesystemspresskit.com/nlos_cannon/development_timeline.cfm
Does it mean it takes 12 seconds from 1 st to 4 th rounds
hitting the targets?

The NLOS-C is expected to be fielded to combat units
by 2017.
