Subject: UK to test fire AS90 Excalibur combination
doggtag    10/7/2008 7:36:23 AM
A British Army AS90 155mm self-propelled howitzer is due to start firing trials with Raytheon XM982 Excalibur GPS-guided projectiles at the US Army's Yuma proving ground in October. It is understood that BAE Systems, as the original equipment manufacturer, has already completed preliminary AS90 flick rammer-compatibility and strength-of-design tests using representative Excalibur rounds [first posted to - 02 October 2008] ----------- (Still amazes me how many news items still list the "X" in the Excalibur's M982 designation. It's no longer an expiremental or prototype system: it is an in-production-status munition, so it's OK to leave the "X" bit off...) Well, our British allies are onboard. Wonder who's next? (Curious to see how far the 52-cal tube of a PzH2000 can toss this puppy...) Any thoughts, ArtyEngineer? (specifically, do you know if the Excalibur is rated/cleared for the higher chamber pressures and launch stresses that 52-cal tubes can generate?)

Yep, the M982 was designed to withstand launch stresses from the Swedish Archer which has a bigger chamber enabling the use of even higher zone charges than the US has the capability to use.  I know exactly how far the Archer can send it but that info not in the public domain so cant divulge sorry ;(  Yuu may have noted as well that the funding for development of Block 2 Excalibur just came on line and that will add rocket assist to the projectile further enhancing its range!!!!

A90 is a standard 39 calibre ordnance (unless the 52 cal is being used in these trials).  Flick ramming seriously 'thunks' the shell into the commencement of rifling.  Theres's also the issue of its handling by the magazine system (shouldn't be a problem) and interfacing whatever device is used to transfer data into the guidance system with the gun's system, which may have to wait for an upgrade to FC-BISA, unless it was designed to accomodate it.
