雷神與美軍完成「新型挑戰者防空搜索雷達」(EASR)測試

固定式與旋轉式兩款雷達,提升海上偵搜距離與性能

  美國海軍與雷神科技(Raytheon Technologies)旗下的雷神飛彈防禦部門,日前在維吉尼亞州的瓦勒普斯島(Wallops Island)海軍測試基地,完成新型挑戰者防空搜索雷達(Enterprise Air Surveillance Radar,EASR)系統的一系列測試。此次測試主要驗證兩款EASR雷達的性能,分別為SPY-6(V)2旋轉式與SPY-6(V)3

  SPY-6(V)2與SPY-6(V)3兩套EASR雷達系統為SPY-6系列的最新雷達,皆可同時執行防空與反水面作戰功能,同時包含無人空中載具之偵察與追蹤、電子防護與航空母艦及兩棲戰艦之飛航管制任務。

  雷神飛彈防禦公司海軍戰力部副總裁Kim Ernzen表示:「EASR能夠快速開發,要歸功於我們的工程師善用了研發SPY-6系列雷達時所累積的知識。透過SPY-6的通用架構可大幅簡化軟硬體的訓練流程與後勤作業所需時間及成本。」

  此次測試聚焦於防空作戰與飛航管制作業,以及SPY-6(V)2與SPY-6(V)3雷達的電力系統模型。未來EASR將取代單一功能的傳統雷達,進一步提升偵搜距離與性能。

  美國海軍整合作戰系統專案執行辦公室的水上感測器專案負責人Jason Hall上校指出:「在高雜波與多目標追蹤環境下,EASR展現了優越性能。研發團隊持續改良、優化系統,後續也會進行雷達與戰鬥管理系統整合之地面測試。」

  AN/SPY-6(V)2預計裝配在兩棲突擊艦與尼米茲級航空母艦上,AN/SPY6(V)3則將用於福特級航空母艦,亦可搭載於各國海軍的巡防艦。未來AN/SPY-6(V)3將成為美國海軍全新星座級巡防艦FFG-62的標準配備。

雷神飛彈防禦公司於2020年3月與美國海軍共同完成工程與製造發展測試,並於2020年7月取得金額1.26億美元的海軍標案,負責產製四套SPY-6(V)2旋轉式雷達以及兩套SPY-6(V)3固定式雷達。

 

 

New eyes for the fleet

Enterprise Air Surveillance Radar gets advancements - sees better and farther

Not so long ago, the U.S. Navy’s two newest radars were nothing more than ideas.

One would rotate. The other would stand still. Together, they would cover the skies nonstop, helping the Navy defend its ships, conduct air traffic control and increase its overall situational awareness.

Now, the SPY-6(V)2 rotating radar and the SPY-6(V)3 fixed-face radar – known together as EASR, or Enterprise Air Surveillance Radar – have completed testing and are about ready to deploy.

“Three years ago, it was PowerPoint presentations, analysis and spreadsheets and here we are preparing to deliver this capability to the fleet,” said David Fenn, senior program manager for EASR at Raytheon Missiles & Defense, a Raytheon Technologies business.

The Navy and Raytheon Missiles and Defense conducted testing at the Surface Combat System Center at Wallops Island, Virginia. The tests focused on anti-air warfare and air traffic control capabilities, weather operations, and power systems for both radars. The EASR will replace single-function legacy radars and improve range and performance.

The radars are part of the SPY-6 family – a group of advanced naval sensors that can find and track targets such as fighter jets, cruise missiles and ballistic missiles, all while resisting interference from the environment, like high waves on rough seas.

Engineers used lessons learned from earlier SPY-6 radars such as the AMDR, or Air and Missile Defense Radar, to develop the new EASR variants quickly.

“Normally, when you do a first-time production build, you have delays, but we finished the first array exactly to the day we said we were going to,” Fenn said. “A lot of that is a result of the work we did on AMDR (Air and Missile Defense Radar) previously.”

Both are highly customizable because they’re built from a common base unit – a two-by-two-by-two cube, and both use variants of the original SPY-6 software, which the Navy has already validated and the business has improved over time.

The AN/SPY-6(V)2 will be installed on amphibious assault ships and Nimitz-class carriers. The AN/SPY-6(V)3 will be incorporated on Ford-class aircraft carriers, and will be a centerpiece of the Navy’s new Constellation-class frigates (FFG 62).

 

One size fits all

The SPY-6 EASR radar is 20 percent smaller than the radars it’s replacing, freeing up deck space.

The smaller size and capabilities make EASR applicable for domestic and international navies. The SPY-6 V(3) version is designed to retrofit onto platforms that previously carried AN/SPS-48 and AN/SPS-49 radars.

 

Commonalities cut costs

Using the same building blocks and software as the rest of the SPY-6 program drives down the operating costs of the radar over its lifetime.

The radars are easy to maintain – they have four basic parts, and it takes only two tools to make any repair.

“The more we can help the Navy reduce their operating and sustainment costs, the better it is for the nation as a whole,” said Scott Spence, program area director for naval radars at Raytheon Missiles & Defense.

In July 2020, the Navy awarded Raytheon a $126 million contract to produce four SPY-6(V)2 rotators and two SPY-6(V)3 fixed-faced radars.

The business is building the first arrays and started near-field range testing in April 2021. The radars are expected to be delivered to the Navy by January 2023.

“The Navy had an idea of what their next-generation radar would be and we’re bringing it to fruition,” Spence said. “We’re not done – this radar will evolve with the threats it has to counter.”
