fired at the maximum range impacted at within 2.2 meters (7.2
feet) from the target's center. Three additional rounds fired
5 degrees off-axis, over a range of 35 km, impacted between
2.8 (9.2 feet) and 6.1 (20 feet) from the target center. The
companies leading the Excalibur team are US based Raytheon and
Swedish based BAE Systems Bofors.
The Swedish Archer 52-caliber howitzer is predicted to achieve
an Excalibur range of approximately 50 kilometers (33 miles).
Upcoming Block Ia-2 tests include full system performance testing,
to include maximum range shots from the Archer, and safety testing
to validate projectile design margins under gun pressures exceeding
normal operating conditions.
