USN Ship Protection: From “Slick 32s” to SEWIP
(click to view full)
The US Navy’s AN/SLQ-32 ECM (Electronic Countermeasures) system uses radar warning receivers, and in some cases active jamming, as the part of ships’ self-defense system. The “Slick 32s” provides warning of incoming attacks, and is integrated with the ships’ defenses to trigger Rapid Blooming Offboard Chaff (RBOC) and other decoys, which can fire either semi-automatically or on manual direction from a ship’s ECM operators.
The “Slick 32” variants are based on modular building blocks, and each variant is suited to a different type of ship. Most of these systems were designed in the 1970s, however, and are based on 1960s-era technology. Unfortunately, the SLQ-32 was notable for its failure when the USS Stark was hit by Iraqi Exocet missiles in 1987. The systems have been modernized somewhat, but in an era that features more and more supersonic ship-killing missiles, with better radars and advanced electronics, SLQ-32’s fundamental electronic hardware architecture is inadequate. Hence the Surface Electronic Warfare Improvement Program (SEWIP).

Overall, SEWIP is a $5.297 billion program, with spending ramping up sharply as of FY 2014.
Though SLQ-32 is a Raytheon system, SEWIP began in 2003 with General Dynamics as the lead integrator. Blocks 1A, 1B2, and 1B3 all use the improved control and display (ICAD) console, which is a GD-AIS upgrade based on the commonly used Lockheed Martin AN/ULQ-70 computing and display console.
SEWIP Block 1A adds the improved displays and a modern interface noted above, along with some hardware switchouts that add modern commercial-off-the-shelf hardware to drive the new display, and handle some signal processing (Electronic Surveillance Enhancements, or ESE).
SWEIP Block 1B1 made more changes to replace obsolete SLQ-32 electronics, some of which aren’t even manufactured any more, and improved the system’s ability to locate the source of incoming radar signals. SEWIP Block 1B1 provides a AN/SSX-1 stand-alone specific emitter identification (SEI) subsystem to ships with the active AN/SLQ-32(V) variant. For small ships, the Small Ship Electronic Support Measures System (SSESM) provides Specific Emitter Identification (SEI) capability in a stand-alone configuration.
SEWIP Block 1B2. For those ships which already have 1B1, this adds federated Specific Emitter Identification, and fully integrates SEI with Block 1A’s ICAD/Q-70 console.
SEWIP Block 1B3 adds additional display upgrades, and a High Gain High Sensitivity (HGHS) subsystem, to help ships deal with modern missiles that announce their presence less boldly and offer less warning time. It received its Milestone C/Low-Rate Initial Production (LRIP) go ahead in summer 2012, and is expected to hit Full Rate Production (FRP) in spring 2014.

Those low-cost, low-risk inserts deal with some of the SLQ-32 system’s issues, but not all. Over the longer term, the system’s fundamental receiver/emitter electronics need to be updated to modern technologies. Its software needs improvements that let ships take better advantage of the new hardware’s capabilities, make it easier to share SEWIP information with their own ship’s combat system, and allow sharing with other ships.
SEWIP Block 2 is described as an upgrade, but it’s more like a major home renovation. It replaces the old SLQ-32 receivers and antennas with modern digital technologies, adding new capability, flexibility, and signal processing muscle. Block 2 also modifies the software, creating a single, unified interface to the combat system in place of multiple interfaces to individual components of the combat system. This makes future upgrades simpler, and may also have the effect of improving performance. Lockheed Martin’s ICEWS materials touted under 200ms end-to-end latency, a low false alarm rate, and good high-pulse throughput for cluttered environments.
The Block 2 contract was awarded to a Lockheed Martin/ ITT partnership at the very end of FY 2009. June 2010 was the next key milestone, and a July 2010 contract continues development. The system passed its Critical Design Review in early 2011, and the partnership was scheduled to deliver 2 prototypes in 2012. This ACAT II program achieved Milestone C approval in January 2013, with approval to begin Low Rate Initial Production, and the contract was restructured to begin LRIP in March 2013. Contracts for production and installation are now underway.
SEWIP Block 3 and beyond could look very different. Block 3 looks to add improvements to SEWIP’s Electronic Attack (EA, or jamming) capability. The goal is a common EA capability to all surface combatants (CVN, CG, DDG, LHA) outfitted with the active V3/v4 variants of the AN/SLQ-32, mainly the (V)3 and (V)4, as well as “select new-construction platforms.” It builds on ESM improvements in Blocks 1 and 2, but isn’t expected to hit its Milestone C Low-Rate Initial Production approval until early 2017. Initial Operational Test & Evaluation isn’t scheduled until summer 2018.
A US Navy program called “Integrated Topside” aims to take all of the little bolt-ons and antennas used for communications, basic radar functions, and electronic warfare, and make them all part of 1 unified architecture. That could help improve ships’ anti-radar profiles, increase their communications bandwidth, and resolve electromagnetic interference and compatibility issues between different devices. New-generation AESA radars have already demonstrated communications and electronic jamming potential, and current research is focused on that technology as the way forward.
SEWIP Block 3T will provide “an initial interim capability of a focused application of the Naval Research Laboratory Transportable EW Module (TEWM) to meet an urgent operational needs statement.”
Contracts and Key Events

LM awarded $153.9M; NG awarded $91.7M
November 30/20: Engineering Services Lockheed Martin won a $14.1 million contract modification for AN/SLQ-32(V)6 design agent engineering services. The AN/SLQ-32 is a shipboard electronic warfare suite built by Raytheon and the Hughes Aircraft Company. It is currently the primary electronic warfare system in use by US Navy ships. AN/SLQ-32(V)6, the latest fielded variant of the AN/SLQ-32, incorporates receiver, antenna and combat system interface upgrades developed under the SEWIP Block 2 ACAT II program and adds the High Gain High Sensitivity adjunct sensor developed under the SEWIP Block 1B3 ACAT II program. Work will take place in Syracuse, New York, and is expected to be completed by November 2021.
January 30/20: Full Rate Production Lockheed Martin won a $185 million deal for follow-on full rate production of Surface Electronic Warfare Improvement Program AN/SLQ-32(V)6, AN/SLQ-32A(V)6 and AN/SLQ-32C(V)6 systems. The Surface Electronic Warfare Improvement Program or SEWIP is an evolutionary acquisition and incremental development program to upgrade the existing AN/SLQ-32(V) electronic warfare system. SEWIP provides enhanced shipboard electronic warfare for early detection, analysis, threat warning and protection from anti-ship missiles. AN/SLQ-32(V)6 is the latest fielded variant of the AN/SLQ-32. It incorporates receiver, antenna and combat system interface upgrades developed under the SEWIP Block 2 ACAT II program and adds the High Gain High Sensitivity adjunct sensor developed under the SEWIP Block 1B3 ACAT II program. Work will take place in New York and Pennsylvania. Expected completion will be by April 2022.
November 11/19: Engineering Services The US Navy awarded Lockheed Martin a $13.9 million contract modification, which is for engineering services and travel for the AN/SLQ-32(V)6 upgrades design agent contract under the Surface Electronic Warfare Improvement Program or SEWIP. SEWIP is an evolutionary acquisition and incremental development program. AN/SLQ-32(V)6 upgrades the existing AN/SLQ-32(V) electronic warfare system by incorporating SEWIP Block 1B3 and SEWIP Block 2 systems. The AN/SLQ-32 is an electronic warfare system that provides powerful countermeasures protection for small and mid-size surface ships. The SLQ-32 systems feature a lens-fed multi-beam array that generates very high jamming power at continuous wave so that an almost unlimited variety of jamming techniques can be used. Work will take place in Syracuse, New York and estimated completion will be by September 2020.
February 11/19: SEWIP full-rate production The Naval Sea Systems Command contracted General Dynamics Mission Systems with a $14.5 million modification to exercise options for Surface Electronic Warfare Improvement (SEWIP) Block 1B3 full-rate production. SEWIP is an evolutionary acquisition and incremental development program to upgrade the AN/SLQ-32(V) electronic warfare system. The AN/SLQ-32 Electronic Warfare Suite or „slick-32“ is the primary electronic warfare system utilized by the US Navy. The system achieves EW objectives by providing full threat band frequency coverage, instantaneous azimuth coverage, 100 percent probability of intercept and simultaneous response to multiple threats. It can detect aircraft search and target radars well before they detect the ship. SEWIP provides enhanced shipboard electronic warfare for early detection, analysis, threat warning, and protection from anti-ship missiles. SEWIP Block 1 focuses on obsolescence mitigation and special signal intercept. Work will take place in Pittsfield, Massachusetts and is expected to be finished by May next year.
December 13/17: Report-Wasting of Funds A report released Monday by the Department of Defense (DoD) Inspector General into the US Navy’s Surface Electronic Warfare Improvement Program has found that the service did not effectively develop and manage electronic warfare capabilities for upgrades to the AN/SLQ-32 Electronic Warfare Suite. The mismanagement resulted in the waste of almost $2 million and lengthened the acquisition process by about two years with inadequate results. Managed by the Program Executive Office Integrated Warfare Systems under Naval Sea Systems Command, the Inspector General found that Navy officials waived a step of the development process—details of which were redacted from the report—in order to stay on schedule instead of correcting problems before entering initial operational test and evaluation. This skipping resulted in additional costs of $1.8 million to conduct a second phase of initial operational test and evaluation on Block 2, delaying the acquisition schedule by almost two years. Program Executive Office Integrated Warfare Systems said it will continue to work with the commander for operational test and evaluation force to close the remaining deficiencies, according to the declassified report.
March 20/17: Lockheed Martin has won a $98 million US Navy contract to produce and deliver the service’s Surface Electronic Warfare Improvement Program systems. The modification covers work for the program’s Block 2 subsystems, which aim to expand upon the receiver and antenna groups necessary to support threat detection and improved system integration. Work will be completed by July 2019.
October 7/15: Northrop Grumman has been handed a $91.7 million contract modification for the SEWIP Block 3’s engineering and manufacturing development phase. The Surface Electronic Warfare Improvement Program (SEWIP)’s Block 3 increment is intended to provide a scalable electronic warfare and electronic attack capability, building on out-of-production AN/SLQ-32(V) electronic warfare systems. Block 2 is already in low rate initial production, following a $147.5 million contract to Lockheed Martin in September 2014.
July 13/15: Lockheed Martin has been awarded a $153.9 million contract modification to supply components for the out-of-production AN/SLQ-32(V) ship electronic warfare system as part of the Surface Electronic Warfare Improvement Program (SEWIP) Block 2 acquisition program.
