New Guns for 1 RCHA...

I doubt if the LAV, which is essentially an armoured 2.5 tonne truck, could support a 12.5 tonne payload in the form of an armoured turret.  Keep in mind as well the need to absorb recoil forces.

The LWSP system basically just carries the gun externally, with autoloading and auto arc adjustment and elevation.  When fired recoil forces are transferred directly to the ground through what appears to be a baseplate.

It is necessary to fit hydraulically operated stabilisers and firing spades to wheeled platforms for the vehicle to withstand the recoil. The LAV would not have any rear compartment but the AGM instead so weight would be reduced compared to the G6 turret on a LAV, for example. It would also probably need stronger suspension.

It has an aotoloader? Can you give me your link because Mr. Google dosen't want to give me any site that says more than '' The LWSP is a variant of the XM777''. Thank you.

Your wish is my command, sire. 

The LWSP is designed for mobility on the ground in support of rapid-manoeuvre forces and in the air by strategic airlift.

The Howitzer is based on the LAV series of fighting vehicles integrated with the ordnance of the ultra lightweight field Howitzer. It weighs 20 tonnes and can be carried by a C130 aircraft. The LWSP is automatic, has 42 rounds on board, a crew of three, and can fire a three-round burst in under 12 seconds.

The LWSP programme is still at an early stage of development, design concepts are being formulated and analysed and there are plans to develop a working prototype by 2004-5. The 120mm AMS (armoured mortar system) is the most mobile and responsive mortar solution, offering maximum crew and system protection and delivering effective firepower to a range of 9.2km.

Only question is: Is this still and ongoing project or has it been back-burnered indefinitely?  The reference is 2002 but the LWSP is still listed on this BAE site as one of their product lines.

LAVs have better armor than M113 and better mobility than Archer.
What is more important is commonality. We already have a lot of LAVs but we do not have any Archer trucks.

The Archer is using a 6x6 Volvo A30D articulated truck, which is commercially available. Additional A30D's can be purchased for other CF needs, but the vehicle is a good off-roader; it serves in particular the mining industry as a hauler, and the vehicle is designed for low maintenance needs. For example, the articulated steering unit is greased for life, and the few fittings that need to be greased are easily accessible through a 90° tilt-up hood, swing-down front grill. The vehicle is also fully controlled by computer; if there is something wrong with the truck, the truck through the computer tells you what is wrong, simplifying maintenance. Parts can be commercially acquired from Volvo, just like with the HESV.

What is of note is that Australia is looking into replacing its 105mm L119 towed howitzer and its M198 155mm towed howitzer through the Land 17 Artillery Replacement Project. Current companies tendering for the project, with first delivery expected in 2010, is Tenix Defence / Bofors Defence AB which is offering the Bofors Archer and the FH77B05 towed 155mm howitzer, and ADI Limited / Giat Industries, which is offering the GIAT CAESAR 155mm howitzer. Since Canada still wants to have a self-propelled howitzer, observing what the Australians will purchase to replace their howitzers can speed up procurement.
