Surface Electronic Warfare

“Right now, every part of the Navy’s fleet has some ability to detect threats,” explains Joe Ottaviano, program director. “But it’s often happening in real-time. They see us, we see them, and both sides are trying to figure out what to do. The Navy’s goal is to get enough information so ships can detect a threat and respond before the other side even knows we’re there.”

The U.S. Navy surface fleet is providing an evolutionary succession of enhancements to its AN/SLQ-32 electronic warfare system currently installed on its ships, with Lockheed Martin’s proven Surface Electronic Warfare Improvement Program (SEWIP). This series of upgrades will incrementally add new defensive technologies and functional capabilities.

Advanced Off-Board Electronic Warfare (AOEW)


What Is It?

The Advanced Off-Board Electronic Warfare (AOEW) program will deliver persistent electronic surveillance (detection) and attack (countermeasure) capability against naval threats like anti-ship missiles (ASM). Lockheed Martin’s AOEW Active Mission Payload (AMP) AN/ALQ-248 system, is a self-contained EW pod hosted by an MH-60R or MH-60S Seahawk helicopter, which provides the Navy advanced ASM detection and response capabilities.
Why It Matters

AOEW allows the Navy to not only see incoming threats, but to respond to them. 
Fast Facts

  • The AOEW AMP AN/ALQ-248 can work independently or with the ship’s onboard electronic surveillance sensor, SEWIP Block 2, to detect an incoming missile and then evaluate where it is going.

Surface Electronic Warfare Improvement Program (SEWIP)

What Is It?

For many years, electronic warfare capabilities aboard surface ships were provided by a passive electronic countermeasures system called the AN/SLQ-32. But an increased— and increasingly more sophisticated—electronic warfare threat prompted the service to upgrade its systems. Enter the Surface Electronic Warfare Improvement Program…SEWIP.
Why It Matters

SEWIP allows sailors to protect the ship from the threats you can see (incoming missiles) to those you can’t (radar jamming). 
Fast Facts

  • SEWIP is a series of evolutionary developments, called block upgrades, which, at each stage improve and modernize the existing AN/SLQ-32 infrastructure.
  • The Navy established SEWIP in 2002. Block 1 provided enhanced electronic warfare capabilities to existing and new ship combat systems to improve anti-ship missile defense, counter-targeting, and counter-surveillance capabilities. The U.S. Navy awarded Lockheed Martin the SEWIP Block 2 contract in 2009 to upgrade the antenna, receiver, and combat system interface for the AN/SLQ-32.

Surface Electronic Warfare Improvement Program (SEWIP) Lite

AN/SLQ-32C(V)6 or “SEWIP Lite” is part of the Surface Electronic Warfare Improvement Program product line. The system provides early detection, analysis, threat warning, and protection from anti-ship missiles. SEWIP Lite is capable of both littoral and open ocean electronic surveillance. This system will be installed on fast frigate class and U.S. Coast Guard Offshore Patrol Cutters.

AN/BLQ-10(V) Submarine Electronic Warfare System

The AN/BLQ-10(V) electronic support system is helping to meet the challenges of today’s and tomorrow’s Navy with a proven, low risk and affordable, electronic warfare system, providing critical analysis in an uncertain and dynamic environment.
