在现代战争中，一场看不见的战斗在电磁波谱中进行。查看和阻止对手攻击的能力需要不断发展的技术。10多年来，洛克希德·马丁公司一直与美国海军合作开发和生产AN/SLQ-32（V）6，这是美国海军水面电子战改进计划（SEWIP）的Block 2演变版。以下是有关此计划的关键功能的五个事实。
1、SEWIP Block 2部署在数十艘阿利伯克级导弹驱逐舰上，最终将部署在几乎所有美国海军水面战斗机上，包括两类濒海战斗舰（LCS）。此外，美国海岸警卫队将受益于其近海巡逻艇舰队的SEWIP Block 2能力。SEWIP Block 2系统为水面舰艇提供反舰导弹的早期检测，分析和威胁警告。它提供的态势感知可以帮助水手保护他们的船只免受这些看不见的射频威胁。
2、Block 2是美国海军用来添加新的防御技术和能力的一系列进化“块”中最新部署的改进。洛克希德·马丁公司的SEWIP Block 2系统于2016年9月从开发计划过渡到全速生产。该系统通过扩大频率覆盖范围、提高灵敏度、先进的电磁干扰保护、更低的生命周期成本和可扩展的开放式架构，在保护水手和船队的能力方面取得了重大进展。根据我们与海军的设计代理合同，SEWIP Block 2的能力和技术将继续发展，以超越现代威胁。

3、洛克希德·马丁公司在纽约锡拉丘兹的团队交付了100千今年夏天向海军提供SEWIP Block 2系统。
我们的团队正在进行第二次，为期五年的全速生产运行。最新的合同确保SEWIP Block 2系统生产到2022年，并可以行使其他选项以继续生产到2024年。
4、通过内部研发、美国海军投资和支持以及与美国海军研究实验室（NRL）和海军研究办公室（ONR）的合作，我们的工程设计团队开发并生产了一个较小的SEWIP Block 2。这种缩放的变体通常被称为SEWIP“Lite”。虽然它可能只有SEWIP的一半左右，但它仍然为尺寸，重量和功率限制有限的小型水面战斗机提供重要的电子支持能力。再加上较低的单系统成本，使SEWIP“Lite”成为许多小型平台（包括LCS）的强大电子支持解决方案。
5、虽然Block 2是美国海军舰队随着时间的推移而开发和实施的多个“批次改进”之一，但SEWIP仍然是美国海军电子战任务的核心。所有其他模块都是围绕Block 2促进的指挥、控制和集成构建的。该系统与宙斯盾作战系统对接，为水面作战指挥官提供电磁波谱的完全态势感知。它可用于提示和控制舰队现在和将来可用的威胁响应库。
In modern warfare, an invisible battle rages across the electromagnetic spectrum. The ability to see and thwart adversary attacks requires constantly evolving technology. For more than 10 years, Lockheed Martin has partnered with the U.S. Navy to develop and produce the AN/SLQ-32(V)6, the Block 2 evolution of the Navy’s Surface Electronic Warfare Improvement Program (SEWIP). Here are five facts about this critical capability.
SEWIP Block 2 is deployed on dozens of Arleigh Burke class Guided Missile Destroyers and will eventually be deployed on nearly all U.S. Navy surface combatants, including both classes of Littoral Combat Ships (LCS). Additionally, the U.S. Coast Guard will benefit from SEWIP Block 2 capability on their fleet of Offshore Patrol Cutters. The SEWIP Block 2 system provides early detection, analysis, and threat warning from anti-ship missiles for surface ships. The situational awareness it provides can help sailors protect their ships from these invisible radio frequency threats.
Block 2 is the latest deployed improvement in an evolutionary succession of “blocks” the Navy uses to add new defensive technologies and capabilities. The Lockheed Martin SEWIP Block 2 system transitioned from a development program to full-rate production in September 2016. The system provides a significant advancement in capability to protect sailors and the fleet with expanded frequency coverage, increased sensitivity, advanced electromagnetic interference protection, lower life cycle costs and a scalable open architecture. Under our design agent contract with the Navy, SEWIP Block 2 capability and technology will continue to evolve to outpace modern threats.
3. Lockheed Martin’s team in Syracuse, NY delivered the 100th SEWIP Block 2 system to the Navy this summer.
Our team is on the second, five-year, full-rate production run. The most recent contract ensures SEWIP Block 2 system production through 2022, with additional options that can be exercised to continue production through 2024.
Through internal research and development, Navy investment and support, and partnerships with the Naval Research Laboratory, (NRL) and the Office of Naval Research (ONR), our engineering design team developed and produced a smaller SEWIP Block 2. This scaled variant is commonly referred to as SEWIP “Lite.” While it may only be about half the size of SEWIP, it still provides significant electronic support capability to smaller surface combatants where size, weight and power constraints are limited. That coupled with a lower per system cost make SEWIP “Lite” a powerful electronic support solution for many smaller platforms, including LCS.
While Block 2 is one of multiple “block improvements” being developed and implemented over time across the US Navy Fleet, SEWIP remains at the core of the U.S. Navy’s electronic warfare mission. All other blocks are built around the command, control and integration facilitated by Block 2. The system interfaces with the Aegis Combat System, giving full situational awareness of the electromagnetic spectrum to the surface combatant commander. It can be used to cue and control the arsenal of threat responses available to the fleet now and in the future.
