to survive this harsher gun launch environment,” said Gibbs. He went on to say, however, “the team learned that the new firing conditions had reduced or eliminated some of the structural capacity due to increased loads at the subsystem and compo- nent level.”
U.S. government and industry engineering teams collaborated in support of the campaign of learning to analyze the individual subsystems’ operating margins, structural integrity and safety margins in order to ensure that the demonstration would be safe and effective in the new ERCA system. With support from the Munitions and Weapons Division at the U.S. Army Test and Eval- uation Command Yuma Test Center, PM CAS and the Combat Capabilities Development Command – Armaments Center, along with Excalibur manufacturer Raytheon, its subcontractors and other industry partners, completed the necessary development and testing to reduce the risk and make the Excalibur 70 km demonstration possible.
CONCLUSION “Today’s demonstration marks a significant step forward in filling a capability gap in our Army of accurately reaching out to 70 km with cannon artillery. It’s the product of tremendous teamwork and initiative by multiple organizations and our industry partners to bring new technology to our artillery forces and regain over- match with our adversaries,” said Brig. Gen. John Rafferty, Long Range Precision Fires Cross-Functional Team director.
By leveraging the robust design of the current Excalibur, a GPS coordinate-seeking projectile with an average miss distance—how far from the target the round detonates—of less than two meters, Excalibur also represents a low-investment, high-payoff approach to meeting objectives in support of the Army’s top moderniza- tion priority, long-range precision fires.
