DD 21 Advanced Gun System will provide the volume of fires and sustainability, improved lethality, and increased range needed for 21st century warfare. It will provide extremely accurate sustained fires using precision-guided Naval and Joint Service munitions with nearly 10 times the range of current shipboard guns. Built by United Defense, the advanced gun will meet the Marine Corps surface fire support requirements. Additionally, the gun system will support other DD 21 requirements:


Reduced manning: The advanced handling system will be fully automatic and unmanned.

Reduced signatures: The gun design, with its above deck structure, will meet the stealth requirement of DD 21.

Reduced O&S Costs: The entire system will have reduced maintenance requirements.


The Advanced Gun System will expand on the Army and Marine Corps 155MM gun and will leverage existing ordnance technologies (ERGM, Army XM982 155MM projectile, SADARM / Unitary warheads, Army Crusader program).


United Defense recommended a traditional pointing gun for DD-21 and the Navy concurred. The Navy decided against a vertical gun for DD-21 in part because "stealth" technologies can reduce the signature of a traditional pointing gun mount and because a vertical gun would not always meet the 100-nm range requirement. Among other disadvantages, the vertical gun would have a shorter range and its projectiles would take longer to reach their target.


Plans now call for a fully automated pointing gun firing 12 rounds per minute. Associated with the gun are gunfire control functionality integrated into the DD 21 Total Ship Computing Environment (TSCE), an automated magazine, and low-radar and IR signatures for the gun and barrel. AGS design includes a family of 155mm extended range guided projectiles with warheads matched to the projected land attack target set. Efforts are underway to achieve as much commonality as possible with US Army 155mm projectiles.

Another DD 21 primary operational capability is maritime dominance - the seagoing component of Joint Vision 2010旧 tenet of dominant maneuver. Maintaining maritime dominance demands better situational awareness, full spectrum offensive engagement capability, robust self defense, and sufficient mobility to employ multi-dimensional forces to provide a decisive advantage over an enemy at sea.


Maritime Dominance is a prerequisite for land attack operations which allows naval forces to first control and then extend the littoral battlespace inland. The effect is to provide Joint and combined forces unimpeded access to strategic and tactical areas of interest ashore. DD 21 will establish and maintain superiority over the surface, subsurface, and local air battlespace by performing a variety of maritime missions including air, surface, submarine, mine, and special warfare, and other fleet support operations.

For air dominance, DD 21 will employ a leading edge radar suite tailored for littoral operations. This radar suite combined with surface-to-air missiles and cooperative engagement capability will support the requirement to establish and maintain local area air superiority. The Multi-function Radar (MFR) is a key part of the next generation AAW System. As low elevation air threats continue to evolve in capability, advances in radar technologies become essential to support operational and manning requirements. MFR, to be designed and built by Raytheon Systems Corporation, is a solid state active array radar system. This radar is more than a cruise missile defense radar. It must provide ulti-function surveillance that can meet the performance requirements in all related mission areas. The Volume Search Radar (VSR) will complement the MFR. It will provide situational awareness, air control, track identification and counter battery locating data. The VSR will provide cue quality track data to the MFR and complement MFR for ship self defense.

DD 21 will operate and support LAMPS helicopters and remote minehunting systems as well as broadband sonars. These organic systems will support a variety of littoral missions including battlespace surveillance, over-the-horizon identification and targeting, in-stride mine avoidance, and localization and destruction of enemy submarines.

To improve survivability in this complex and dynamic environment, DD 21 will be designed with 昼tealth?technologies to reduce its visual, radar, infrared, acoustic, and magnetic signatures. DD 21 will have an integrated topside design with an advanced superstructure and advanced multi-function apertures. In addition to improving self-defense, DD 21 revolutionary signature reduction will greatly enhance its offensive capabilities by allowing it to operate closer to shore despite threat conditions. The unique notional DD 21 hull form is a dramatic visual representation of the vastly reduced signatures envisioned for this combatant. As the first U.S. warship to incorporate an integrated approach to signature reduction, DD 21 is the critical bridgehead for development of these technologies. While specific types of signature-reducing technologies will not be disclosed until the Navy downselects to one industry team ship design concept in 2001, requirements to reduce DD 21's radar signature necessitate an integrated topside design

(i.e. reduced signatures through the use of an advanced superstructure incorporating embedded multi-function apertures for antenna and electronic systems). The ship design will also likely include radical composite construction materials, some radar absorbing materials, and optimized hull shaping both above and below the waterline. Extensive attention will also be given to acoustic quieting and degaussing for both equipment and propulsion systems. The integrated power system is expected to provide substantial quieting capability.

朱瓦特級艦 美造艦工藝總體結晶

（作者／資深軍事專欄作家-陳維浩 ）








美國國防部於一九九○年代展開的DD-21計畫，乃是設計建造一全新的未來水面作戰艦，並將以該型驅逐艦為基礎，發展包含巡洋艦、巡防艦等一系列大小不同的水面作戰船艦，構成美國海軍未來的作戰主力。DD-21計畫由於過於龐大，受到美國國會的預算監督，在經過重新調整後，於二○○一年十一月被名為DD（X）的計畫所承襲；二○○五年底，美國國會終於決定建造八艘DD（X）驅逐艦，並由美國國內兩大造船廠分別建造首批兩艘船艦，美國海軍則在二○○六年四月，將首艘船艦命名為DDG-1000朱瓦特（Zumwalt）號，預定二○○八年開始興建，二○一三年服役。

光電設備一體化於船艛內


朱瓦特級驅逐艦不僅是美國新一代海軍船艦，其在諸多方面，都為各國未來的海軍作戰艦立下標竿。該艦最明顯的特色，莫過於迥異於當代船舶的特殊外觀，從吃水線以上便完全朝內傾斜的船型，取消桅桿與煙囪，而將各種通信與雷達天線、光電設備完全內嵌於一體化的船艛內，加上力求簡潔的武裝與甲板佈局，使其雷達匿蹤效果較現今船艦更上層樓。吃水線較甲板突出的尖銳船艏，亦有別於一般船舶，除上述匿蹤考量外，這樣的設計能在惡劣海象航行時，獲得更佳的穿浪效果。


在水面下的輪機推進部分，亦屬先進科技，該艦以兩座燃氣渦輪推動發電機，並透過整合電力系統，將電力供應給兩座電力推進主機與船艦本身使用，此推進方式除了較傳統輪機更易於控制船速外，也能有效降低船身震動與水中噪音。不過相對於致力提高航速的濱海戰鬥艦(LCS)，朱瓦特級的最高航速僅為三十節，與現今水面作戰艦相去不遠。

掛載改良型戰斧巡弋飛彈

船殼採內外雙層構造，內層設有裝甲防護以提高防禦力。不同於現役美軍軍艦，朱瓦特級的新一代垂直發射系統設置於兩舷的內外船殼間，並分列在前段甲板與後方的直升機甲板旁，左右舷各有十座(四十組)，可發射改良型麻雀飛彈(ESSM)、標準二型與標準三型飛彈、垂直發射反潛火箭，以及射程可達三千公里的改良型戰斧戰術巡弋飛彈等。


此外朱瓦特級上用於對空、對海與射控的雙頻主動陣列雷達，除改進美軍現役神盾艦SPY-1雷達對低空目標因應能力不足的問題，利用強大的搜索追蹤性能，也能配合搭載的標準三型飛彈，構成彈道飛彈防禦的一環。
