US NAVY RELEASES SEWIP BLOCK 3 RFP
Block 3 Statement of Work. Each hemisphere will provide 180 degrees of coverage divided into 90-degree quadrants.
Additionally, there will be two types of
coverage – one for ships with large radar
cross sections, such as aircraft carriers,

About the same time that the two
Engineering Development Models enter
government testing in early 2017, the
Navy also plans to begin low-rate production of six systems. Full-rate production is scheduled to begin in early 2019.

The Journal of Electronic Defense | March 2013

Naval Sea Systems Command (Washington, DC) has issued a request for
proposals (RFP) for development of a
new electronic attack subsystem to be
integrated into its SLQ-32 shipboard EW
system, which is widely deployed across
its fleet of surface combatants. Known
as the Surface Electronic Warfare Improvement Program (SEWIP) Block 3 (see
JED, January 2013, p. 24), the aim of the
$400 million program is to develop and
integrate a high-power jammer that can
defeat modern coastal and ship-based
radars and a wide variety of advanced
anti-ship cruise missiles.
For the past decade, the Navy has
been upgrading the SLQ-32’s processors
and implementing an open architecture
(SEWIP Block 1). In 2009, it began an effort (SEWIP Block 2) to replace the electronic support subsystem with a new
wideband digital receiver suite. Block
3 will add a robust jamming capability
that will help to ensure that Navy surface combatants can operate in complex
and high-threat littoral environments
in which an adversary may launch multiple simultaneous long-range anti-ship
cruise missiles from aircraft, coastal batteries, surface vessels and submarines.
According to the program schedule,
the Block 3 development contract will
be awarded in June. It will kick off
with a six-month Preliminary Design
(PD) phase that will include a System
Requirements Review and a Systems
Functional Review. PD will be followed
by an Engineering and Manufacturing
Development (EMD) phase scheduled to
begin in November. During EMD, the
contractor will deliver two Engineering
Development Models in December 2016
and January 2017. The first of these
two production representative systems
will include a full “Below Decks Equipment Group” providing 360-degree of
topside coverage configured to provide
two “hemispheres,” according to the

15

and one for smaller radar cross sections,
such as frigates. The second Engineering Development Model will provide just
90 degrees of topside coverage configured into one 90-degree quadrant for
ships with small radar cross section.
One important aspect of the program
is the requirement for a modular open
system architecture (MOSA) approach. In
addition, the program will focus on key
technical performance measures, such
as effective radiated power, technique
generation, interference mitigation and
conducting simultaneous engagements.
Some of the early technology maturation for SEWIP Block 3 has been
funded through the Office of Naval
Research-sponsored Integrated Topside (InTop) program, which has demonstrated, among other technologies,
active electronically scanned arrays for
jamming applications.

So far, only one team has announced
their intention to compete for SEWIP
Block 3. Lockheed Martin MST (Liverpool, NY) has teamed with Raytheon
Space and Airborne Systems (El Segundo, CA). However, the program is
likely to also attract other EW systems
manufacturers, such as Northrop Grumman Electronic Systems (Baltimore, MD)
and possibly BAE Systems Electronic
Systems (Nashua, NH) and ITT Exelis
(Clifton, NJ). All of these companies are
pursuing the Navy’s Next Gen Jammer
program, which is expected to make use
of Gallium Nitride (GaN)-powered AESA
technology to generate high-power, narrowly focused jamming beams that can
jam advanced radars and threats from
long distances. The SEWIP Block 3 requirement could be met by this type of
approach. Proposals are due April 15. –
