SHIPBOARD ELECTRONIC WARFARE SYSTEMS
for operational testing. Full-rate production of Block 2 began
in October 2016. A variant of Block 2, the SLQ- 32(V) 6, known
as “SEWIP-Lite,” was developed for the LCSs.
Northrop Grumman was awarded a contract in October
2015 to develop Block 3 with improved electronic attack capabilities as the SLQ- 32(V) 7. Preliminary design review was
completed in August 2015. IOC is scheduled for 2019. A future
Block 4 will provide electro-optic and infrared capabilities to
the SLQ- 32.

SLD- 4 ESM SYSTEM
BRIEFING: The SLD- 4 is an ESM suite installed on LCSs. The
systems provide detection and identification of emitters for
integration into the ship’s combat system.
CONTRACTOR: . . . . . . . . . . Harris Corp.
WLR- 1 RADAR WARNING SYSTEM
BRIEFING: The WLR- 1 is installed on many Navy ships and
submarines. The latest version, the WLR-1H(V) 5, features
reliability improvements and is designed to perform area
surveillance for electronic emitters, as well as detection, classification and targeting of emitters.
WLQ- 4 ESM
BRIEFING: The WLQ- 4 is an ESM system installed on
Seawolf-class attack submarines. It can be operated fully
automatically to detect, identify and locate radar and communications emissions and, through digital computers, correlate
intercepts with other sources of intelligence.

SLR- 25(V) 1 ADVANCED
EXPLOITATION SYSTEM (ACCES)
AND SLR- 25(V) 2 SHIP SIGNAL
EXPLOITATION EQUIPMENT (SSEE)
BRIEFING: The SLR- 25 is a shipboard cryptologic exploitation
system used for tactical surveillance and targeting; indications
and warning; and passive detection, classification and tracking. The system also provides for interpretation and reporting
of intercepted signals, geographic plot and analysis and track
The SLR- 25(V) 1 ACCES is a portable version of the SLR-
25(V) 2 SSEE for ships without a permanently installed
cryptologic capability. When paired with a Transportable Radio
Direction-Finding System, the ACCES provides a complete
SIGINT collection system. The ACCES is being integrated into
amphibious assault ships and Arleigh Burke-class destroyers.

SSQ- 137 SSEE INCREMENT E/F
BRIEFING: SSEE Increment E is an evolutionary development,
spiral acquisition Tactical Cryptologic System whose function is to provide comprehensive tactical information warfare
(IW) exploitation and ESM capability to the Navy’s surface
platforms. SSEE Increment E, an afloat IW sensor, provides
commanders with threat search and identification information
and electronic attack options.
Increment E, an open-architecture system upgraded
with software changes, replaced an array of communications
intelligence systems. Increment F, which features improved
receiver sensitivity, signal acquisition and direction finding,
entered low-rate production in April 2010 and achieved IOC
The Navy has ordered 113 Increment F systems. In May
2014, the Navy ordered the first set of improvements under
the SSEE Modifications program to improve the ability to
detect, geo-locate and exploit signals.

LOGISTICS UPDATE (COBLU)
BRIEFING: COBLU is a joint U.S.-U.K. project to update the
SSQ- 108 Organizational Unit Tactical Baseline Operational
Area Radio Detection (OUTBOARD) direction-finding system
to provide comprehensive surface tactical IW exploitation
and ESM capability to surface ships. OUTBOARD has made
use of high-frequency deck-edge HF antennas and VHF mast
antennas, as well as a receiver that automatically searches for,
collects and analyzes signals.
