Naval Technology: the DD(X)

The Weekly Standard covers the Navy's new DD(X) destroyer, the aquatic equivalent of the stealth bomber. Its unique electronics, low profile in the water, and construction using radar-resistant materials are all interesting facets. But:

...the most intriguing element of DD(X) is its guns. Each 155mm gun will fire a Long Range Land Attack Projectile (LRLAP). The LRLAP has already been successfully tested to 83 nautical miles. Though it only carries 24 lbs of high explosives, the Advanced Gun System (AGS) is fully automated and holds a magazine of 300 rounds. With a rate of fire of 10 rounds a minute, the AGS should be able to provide the volume fire capability the Navy so desperately needs, and with GPS-guidance the LRLAP will be extremely accurate. Critics of the AGS point out that accuracy of fire may be less important than the volume of fire when softening up onshore targets for an amphibious assault, but because the DD(X) can be replenished while at sea (and while firing), she will be able to fire at least one gun continuously for an indefinite amount of time. In addition, each gun will be capable of putting up to eight rounds on a target simultaneously. To achieve this effect, shells will be fired in rapid succession at different trajectories. In conjunction with the counter-battery capability of the dual band radar, any enemy troops who fire on U.S. forces will have only minutes before the 2 guns of DD(X) can return fire with devastating accuracy: Tests have shown the guns accurate to within two meters at a range of 68 nautical miles...
