The SM-6 ERAM (Extended Range Active Missile) is an under development upgraded version of the SM-2 designed to hit both aircraft and high performance cruise missiles. The missile combines the proven SM-2 airframe with a seeker from an AIM-120 AMRAAM missile. By utilizing the seeker from the AIM-120 AMRAAM missile, the SM-6 can offer the capability to hit targets outside the ships radar horizon, and therefore offer increased range as well as accuracy. The missile also takes advantage of both the SM-2 and AIM-120 AMRAAM's datalinking capability, and because it requires very little development is expected to be inexpensive to procure.

Standard Missile-6 Completes Key Design Review Early

By Marc Selinger

The U.S. Navy's Standard Missile-6 (SM-6) program has completed a key design review three months ahead of schedule and with a positive outcome, according to a service official.

이 미사일의 Key design review 가 3개월 일정을 당겨서 좋은 결과로 마무리 되었다고 합니다.

"We were pretty pleased with the overall results of the design review," said Capt. Mick Outten, who manages surface-ship weapons programs for Naval Sea Systems Command. "We don't see any major issues."

결과에 만족한다는 언급.

The preliminary design review (PDR) for SM-6, also known as the Extended Range Active Missile (ERAM), was moved up from September to the last week in June, as many activities leading up to the review took less time than projected.

SM-6(=ERAM) 의 PDR이 당초 9월에서 6월에 완료되었다는 내용.

"We've gotten through some of the wickets sooner than we expected," Outten told The DAILY in an Aug. 3 interview.

For instance, the program thought it would take 12 to 14 months to build and test the seeker's antenna, but that task ended up taking less than eight months because of knowledge the Navy gained from looking at other programs.

예를 들어 미사일 seeker 의 안테나를 시험하는데 통상 12~14개월이 걸리는데, 8개월 만에 끝났다는군요.

The biggest recommendation resulting from the PDR was that the missile's complex software undergo robust tests.

PDR을 통해 나온 최대 이슈가 미사일의 복잡한 소프트웨어에 대한 시험이라는군요.

The early PDR could pave the way to hold the critical design review earlier in 2006 than expected.

Homeland defense?

Designed as an extended-range, ship-launched missile to destroy aircraft and cruise missiles, SM-6 will combine the propulsion and ordnance sections of Raytheon's existing Standard Missile-2 Block IV with a modified version of the seeker used on Raytheon's existing Advanced Medium Range Air to Air Missile (AMRAAM). Raytheon was awarded a $440 million contract in September 2004 for ERAM's system development and demonstration phase (DAILY, Sept. 7).

이 미사일은 SM-2 Block IV 추진체와 탄두를, AMRAAM 공대공 미사일의 seeker와 결합시키는 것으로, 함상에서 발사하여 장거리의 적기 나 순항미사일을 격추하는 목적으로,

Raytheon 이 2004년 9월에 $440mil(4억 4천만 달러=약 4천4백억원)의 SDD 단계 개발을 수주하였다고...

The Navy and the U.S. Missile Defense Agency are looking at whether SM-6 could also be used to destroy short-range ballistic missiles in their terminal phase of flight. In addition, there have been talks about the utility of a land-based version of ERAM for homeland defense.

SM-6를 단거리 탄도탄의 마지막 진입단계에서 요격하는 목적으로 가능성을 주시하고 있으며, (함상용으로 앞서 올린 내용 참조하세요), 육상에서 사용하는 방안도 검토되고 있군요.

SM-6 is projected to have a range of more than 200 miles, compared with the 75-plus-mile reach of the Navy's main air defense weapon, the SM-2 Block IIIB.

사정거리가 200mile(320km)이상으로 계획/개발 중으로, 해군의 주력 대공미사일인 SM-2 Block IIIB 는 75mile+(120km+)의 사거리를 갖는다는 내용 입니다.

ERAM will combine a semi-active seeker with AMRAAM's active seeker. While a semi-active missile uses the launcher's radar signals to home in on a target, an active-seeker missile has its own radar for that purpose.

semi-active seeker와 암람의 active seeker를 조합하는군요.

"With semi-active missiles, you are relatively confined to the line of sight from the launch platform to the target," Outten said. "But once we can go to a full active missile, then that gives you the opportunity to reach out and touch things where we haven't been able to do it before from a surface ship."

각 seeker 유도 방식에 대한 설명... 생략

Despite the advantages of an active seeker, SM-6 also will have a semi-active capability to provide "a little more homing time" in some situations against fast, high-altitude targets at long ranges, he said.

장거리, 고고도, 빠른 비행 목표물에 대한 유도를 위해, semi-active를 함께 사용한다는 설명.

Advanced software will closely monitor the missile's condition aboard a ship, meaning that the weapon will have to be sent to a recertification facility only every 10 to 15 years compared with every four or five years for older Standard Missiles.

개량된 소프트웨어가 미사일 상태를 자동 점검하는 관계로 미사일을 과거 SM과 같이 4~5년 마다 재점검이 필요치 않으며, 10~15년에 한번 recertification facility 에 가면 된다고 합니다.

SM-6 is slated to begin flight-tests in late 2007, enter low-rate production in mid-2009 and achieve an initial fielding in fiscal 2010. The missile's cost goal is $2.2 million a copy, but the actual price tag could end up below $2 million, Outten said.

2007년에 발사시험, 2009년에 생산, 2010년에 배치를 목표로 하고 있으며, 비용은 1기 당 $2.2mil(약 22억원)을 계획하고 있으나, $2mil 이하로 가능할 것 이라고 합니다.

ERAM will be deployed on Aegis cruisers and destroyers and on the future DD(X) destroyer and CG(X) cruiser. The Navy has not yet determined how many ERAMs it will buy, partly because it is still assessing how many ships it will have, Outten said.

ERAM은 현 이지스 순양함/구축함 및 장래의 DD(X) destroyer 와 CG(X) cruiser 에도 장착 될 것으로 아직 해군의 구매 수량은 미정이라고 합니다. [유용원의 군사세계]
