SPY-6가 납품돼면서 SPY-1이 달렸던 DDG로는 활용할 수 없었던 SM-3의 장사정 능력을 100% 활용할 수 있다고 레이시온의 켄 스펄록 국장이 주장했다고 합니다. 

SPY-6는 항공 및 미사일 동시 방어가 가능하며 유기적인 지역방공능력을 제공하고 전장인식 능력을 개선하며 종심방어 능력을 강화하고 우군오사 위험이 줄었으며 표적 격추에 필요한 미사일 숫자를 줄여 준다고 하네요. 

SPY-6 (V1): 알레이 버크급 플라이트IIIA에 장착. 4면 고정형, 면당 RMA(radar module assemblies) 37개

SPY-6 (V2) EASR(Enterprise Air Surveillance Radar): 회전식, 면당 RMA 9개, 아메리카급/와스프급 강습상륙함, 샌안토니오급 LPD, 니미츠급 항공모함에 장착 예정

SPY-6 (V3) EASR: 3면 고정형, 면당 RMA 9개, 포드급 항모와 콘스털레이션급 호위함에 장착 예정

SPY-6 (V4): 4명 고정형, 면당 RMA 24개, 알레이 버크급 플라이트IIA 일부에 교체장착 예정

The SPY-6(V)1 is being installed on Flight III Arleigh Burke-class DDGs. This air-and-missile-defense radar has been installed on the future USS Jack H. Lucas (DDG 125), shown here, scheduled to join the fleet in 2024. HII

ARLINGTON, Va. — The SPY-6 air and missile defense radar, the first of which has been installed on a guided-missile destroyer, will give the Navy a sensor worthy of its long-range Standard SM-3 Block IIA surface missiles, Raytheon officials said. 

Briefing reporters April 1, Ken Spurlock, Raytheon’s Strategic Missile Defense Requirements & Capabilities director, said the SM-3 missile “out-shot” the capabilities of earlier radars — presumably the SPY-1 on earlier DDGs. With the SPY-6, the SM-3 “can engage at the maximum range possible” for the missile. 

Spurlock said the SPY-6 allows a ship to provide air and missile defense simultaneously, provide regional defense organically, offer greater clarity of the battlespace, give more defense in depth, reduce the risk of fratricide and reduce the number of missiles needed to defeat a target. 

Also briefing was Michael Nulk, Raytheon’s associate director, Requirements and Capabilities – Naval Power, said the SPY-6 will give commanders the discrimination capability to make better decisions and to “change their shot doctrine.” 

“There is no other radar with the surface maritime capabilities of SPY-6,” Wes Kremer, president of Raytheon Missiles & Defense, said in a March 31 release. “SPY-6 is the most advanced naval radar in existence, and it will provide our military a giant leap forward in capability for decades to come.”  

Raytheon Missiles & Defense was awarded a $651 million Naval Sea Systems Command contract, with options totaling $2.5 billion, for “hardware, production and sustainment for full-rate production” of the SPY-6 family of radars. The contract provides for five years of production for radars for up to 31 U.S. Navy ships of seven types.  

Scott Spence, naval radars executive director at Raytheon Missiles & Defense, also briefing reporters, said the company had 46 SPY-6 shipsets under contract, with six of those in work at the Raytheon plant. He said the enlarged footprint of the SPY-6 production will help reduce sustainment costs.  

Spence noted the last transmitter that Raytheon builds for the SPY-1 radar will be delivered in April, concluding 41 years of production for the SPY-1. 

The SPY-6 family includes the SPY-6(V)1, being installed on Flight III Arleigh Burke-class DDGs. The (V)1 has four flat antenna faces each with 37 radar module assemblies. This air-and-missile-defense radar has been installed on the future USS Jack H. Lucas (DDG 125), scheduled to join the fleet in 2024. The second shipset has been delivered for installation on the future USS Ted Stevens (DDG 128). 

The SPY-6(V)2 Enterprise Air Surveillance Radar (EASR) has a rotating face with nine RMAs. The (V)2 will equip the America-class and Wasp-class amphibious assault ships, San Antonio-class amphibious transport dock ships, and Nimitz-class aircraft carriers. 

The SPY-6(V)3 EASR has three fixed faces each with nine RMAs. The (V)3 will be installed on Ford-class aircraft carriers and Constellation-class guided-missile frigates. 

The SPY-6(V)4 EASR will have four fixed faces each with 24 RMAs. The (V)4 will be back-fitted on some Flight IIA Arleigh Burke-class DDGs.

RCS가 낮은 표적은 SPY-1에 늦게 탐지되어 이런 표적에 대해서는 SM-3 Block IIA를 빨리 쏴서 촤대 사거리를 다 써먹을 수 없었지만 이제 SPY-6으로는 그것이 된다는 뜻이겠죠?

SM-3가 탄도미사일 방어용이니 아마도 대탄도탄 방어 능력이 좋아졌단 말이기도 한 것 같습니다.

미사일-항공기 동시방어가 가능해졌다는 얘기는 탄도미사일 방어에만 해당되는 얘긴지 대함미사일 등 요격에도 적용되는 얘긴지도 궁금합니다. 미사일 요격 모드면 항공기급 표적의 탐색-추적이 안된다는 얘긴지.. 탄도미사일 방어면 머리 위를 집중적으로 살펴야 하니 그럴 것 같기도 하고.

SPY-1도 베이스라인9부터 고고도의 탄도탄 임무와 저고도의 대공전 임무를 동시에 할 수 있게 되었다고 했던 것 같습니다만... (순양함용 B를 제외하면)SPY-1D보다 주사율의 향상이 있지 않을까요? 원래 SPY-1D는 1면씩 작동하다가 V형부터 2면씩 작동하여 주사율이 향상되었습니다. AESA인 SPY-6에서 4면이 동시에 작동한다면 더 나아지겠죠.
