SHIPBOARD RADAR SYSTEMS
optimized to track small, fast-moving targets such as swarming
small boats. The SPS- 75 is installed on Freedom-class LCSs.
Beginning with LCS 17, the TRS-4D will be installed on the
Freedom class. The TRS-4D is a software-reprogrammable C-band
active electronically scanned array radar allowing for greater sensitivity to detect smaller targets with greater accuracy.

SPS- 77 SEA GIRAFFE AMB RADAR
BRIEFING: SPS- 77 is the new designation for the Sea Giraffe, a
three-dimensional agile multibeam (AMB) radar designed to perform surveillance, fire-control, gunfire support and helicopter
control. The radar is optimized to track small, fast-moving targets
such as swarming small boats, anti-ship missiles and anti-radiation missiles. The Sea Giraffe is installed on the

BRIEFING: The BPS-15/16 radars are installed on submarines
for navigation and surface surveillance. Variants are installed on
all current classes of U.S. submarines. The X-band radars feature
Automatic Radar Plotting Aid support for target tracking in real
time, along with user configurable target symbols to assist in
accurately determining past, present and future target positions.
The newest version, being installed on Block III Virginia-class
SSNs, is the BPS- 16(V) 5, fully integrated with the submarine’s
tactical local-area network.
CONTRACTOR: ...........Northrop Grumman Corp.
BRIEFING: The AIS is a commercially available shipboard broadcast VHF maritime band transponder system that can transmit
ship information, including navigation, identification and cargo.
AIS is mandated by the International Maritime Organization for all
merchant vessels of more than 300 tons. Warships are exempt.
AIS significantly increases the ability of the Navy and allied
nations to distinguish between normal and suspicious merchant
ships headed toward U.S. and allied ports. Navy warships using
AIS have observed dramatic increases in situational awareness,
ship safety and intelligence gathering. In 2005, Navy leaders identified AIS as an urgent capability and directed fielding of standalone AIS on all warships by fiscal 2006 and integrated AIS
(machine-to-machine data integration with GCCS-M) in 2007-
2011. AIS was granted Rapid Deployment Capability authority in
January 2006 and transitioned to a program of record in 2008.

BLQ- 10 ELECTRONIC SURVEILLANCE
MEASURES (ESM) SYSTEM
BRIEFING: The BLQ- 10 is an advanced SIGINT surveillance
system for submarines, designed to support operations in the
littoral or open-ocean environment. It enables detection, identification (to a specific emitter), analysis and direction finding of
radar and communications signals of interest. The BLQ- 10 also
aids in gathering intelligence. First deployed in 2000, it is being
installed as a common SIGINT suite in all operational Navy submarines.
CONTRACTOR: ...........Lockheed Martin Corp.
SLQ- 25 NIXIE
BRIEFING: The SLQ-25C is a towed decoy electro-acoustic
jammer designed for torpedo defense of surface ships. It emits
simulated ship noise intended to draw away incoming torpedoes.

SLQ- 32 ELECTRONIC WARFARE SYSTEM/
SURFACE ELECTRONIC WARFARE
IMPROVEMENT PROGRAM (SEWIP)
BRIEFING: The SLQ- 32, introduced in the early 1980s, is the
Navy’s primary shipboard electronic warfare system. It has provided the capability to passively detect threat radar emissions,
particularly those from radar-guided anti-ship cruise missiles,
and classify the type of radar. About half of the fleet’s SLQ-32s,
predominantly those on larger ship classes, also have an active
radar jamming capability. The SLQ- 32(V) systems are undergoing an evolutionary upgrade through the Surface Electronic
Warfare Improvement Program.
SEWIP is an incremental block upgrade and replacement program for the SLQ- 32 aboard several classes of Navy combatant
ships. The Block 1A upgrades, approved for full-rate production
in August 2006, replace the original signal processor with the
COTS Electronic Surveillance Enhancement processor and the
display console with the Navy standard UYQ- 70, both of which
are integrated with improved control and display software.
Block 1B integrates a standalone SSX- 1 Small Ship Electronic
Support Measures System already in production at General
Dynamics, adding a specific emitter identification capability.
The Coast Guard also has ordered SSX- 1 systems.
Block 1B3, approved for low-rate production in August
2012, provides improved situational awareness.
Lockheed Martin was selected in November 2009 to produce
a preliminary design for the Block 2 phase that will entail more
significant improvements, including a new antenna and receiver. Block 2 was approved for low-rate production in January
2013. Ten systems were procured, with 14 more ordered in
September 2014 and additional units ordered in 2015. The
Block 2 was installed on USS Bainbridge in July 2014 for operational testing.
A variant of Block 2, the SLQ- 32(V) 6, known as “
SEWIP-Lite,” is being developed for the LCSs.
Northrop Grumman was awarded a contract in October 2015
to develop Block 3 with improved electronic attack capabilities as
