レイセオンが開発した新型のGPS誘導Excalibur N5 round弾は、
26海里(48km)先を、2ｍの誤差範囲のピンポイントで撃ち抜くことができるようになります。
従来は艦を中心に200平海里の有効射撃圏内だったものが、これによって2000平方乖離までになります。

A new Raytheon-developed GPS-guided Excalibur N5 round, however, can pinpoint target out to about 26 nautical miles, Paul Daniels, Raytheon business development, Excalibur, told Scout Warrior in an interview.

"We're more than tripling the max effective range of the Mk 45 five inch guns and providing
Excalibur precision with less than 2-meters miss distances at all ranges,” he said.
“Think of the area that you can cover as a commander of a ship -- that is about 8
nautical miles, 200 squared nautical miles around your ship to more than 2,000 square miles,” Daniels said.

遠距離精密射撃が可能になることで空母打撃群の防衛能力が上がるだけではなく
揚陸強襲部隊への強力な支援も可能になります。

we are not backing away in any sense from the
requirement to ensure the continued defense of our aircraft carriers, ensure the
continued defense of our amphibious ready groups, ensure the continued defense of our
logistics train,” Rowden said at the symposium.
The extended range of the Excalibur N5, Daniels explained, could prove valuable for
amphibious Marine Corps forces in need of fire support while approaching shore.
