aircraft carrier. It combines an air search radar and precision-tracking radar into a single system, with each operating simultaneously in a different frequency band while sharing a common processing and control suite. Both are advanced, electronically
steered, phased-array radars that will be the first to enter service
on a Navy ship.
The S-band three-dimensional VSR will search for high-flying
threats at long range and hand over targets to an X-band fire-control radar, the SPY- 3. The SPY- 3 will search close around the
ship and rapidly out to the horizon to detect fast, low-altitude anti-ship missiles and aircraft. The DBR will be fully automatic, requiring no dedicated operator and no manned display consoles.
The DBR completed its critical design review in November
2009. In 2010, the Navy decided to install only the SPY- 3 on the
Zumwalt-class destroyer, with software modifications to compensate for the lack of a VSR.

SPY- 6 AIR AND MISSILE DEFENSE
BRIEFING: The SPY- 6 AMDR is a program to develop the next
generation of shipboard air defense radars. The AMDR X-band
radar will provide horizon search, precision tracking, missile
communication and terminal illumination.
The AMDR S-band radar provides volume search, tracking,
BMD discrimination and missile communications. A radar suite
controller will integrate the radars with the ship’s combat system. The AMDR suite will be scalable for multiple platforms.
In October 2013, the Navy selected Raytheon to design and
build the S-band portion of the AMDR and the radar suite controller. A version of the SPQ-9B radar will fill the X-band requirement. In July 2014, the AMDR completed its hardware preliminary design review and integrated baseline review. The radar conducted a successful tracking of a simulated target in November
2014. Critical design review was completed in May 2015.
The AMDR will be installed on Flight III Arleigh Burke-class
DDGs beginning in 2016.

ENTERPRISE AIR SURVEILLANCE
BRIEFING: The EASR will be a new-design air surveillance radar
for the second Ford-class aircraft carrier, John F. Kennedy — in lieu
of the Dual-Band Radar — and the America-class amphibious
assault ships starting with LHA 8. It also will be installed on the
LX(R). The Office of Naval Research is working with Raytheon on
development studies. The EASR program will be competed.
Initial operational capability (IOC) is planned for 2025.
CON TRACTOR: ........... TBD
BRIEFING: The SPQ-9B is an X-band, high-resolution, rotating
phased-array radar designed to detect and track low-altitude
cruise missiles in a high-clutter environment. The pulse-
Doppler track-while-scan radar allows detection and tracking at
long ranges, giving a ship’s combat systems time to engage an
incoming supersonic missile at the maximum ranges of its
defenses. The SPQ-9B is integrated with the SSDS onboard air-
craft carriers and amphibious assault ships and with the Aegis
Combat System as part of the Cruiser Modernization Program
and Destroyer Modernization Program.
CONTRACTOR: ...........Northrop Grumman Corp.
SPS- 48 RADAR
BRIEFING: The SPS-48E S-band three-dimensional radar is a
long-range air-detection and tracking radar installed on aircraft
carriers and some amphibious warfare ships. In April 2006, the
Navy awarded ITT Gilfillan a four-year contract with a potential
value of up to $30 million to develop a modernized SPS-48G(V)
under the Radar Obsolescence, Availability Recovery (ROAR)
program. ROAR will cut the total cost of ownership (including
maintenance) by reducing the impact of obsolescence in major
subassemblies and improve operational availability. Once fully
implemented, it will enable the SPS- 48 to remain in service
through 2050. The first SPS-48Gs were delivered in October
2009. The SPS-48G is being installed on aircraft carriers,
amphibious assault ships and amphibious transport dock ships.
The Navy has begun a study to explore options to replace the
SPS-48/49 on aircraft carriers and amphibious assault ships.

SPS- 49 RADAR
BRIEFING: The SPS- 49 L-band radar is a long-range, two-dimensional, air-search radar installed on many Navy ships. On
Ticonderoga-class Aegis cruisers, it also complements the SPY- 1
radar suite. The Navy has begun a study to explore options to
replace the SPS-48/49 on aircraft carriers and amphibious
CONTRAC TOR: ...........Raytheon Co.
BRIEFING: The SPS- 67 and SPS- 73 are surface search and navigation radars used on many classes of surface ships. The SPS-
74 is an X-band surface search radar optimized for submarine
periscope detection and installed on four aircraft carriers.
Further SPS- 74 production was canceled in favor of the SPQ-9B
with periscope-detection capability.
CONTRACTORS:.........Northrop Grumman Corp. (SPS-67/74),
Raytheon Co. (SPS- 73)
SPS- 75 TRS-3D RADAR
BRIEFING: SPS- 75 is the new designation for the TRS-3D, a three-dimensional multimode radar designed to perform surveillance,
fire-control, gunfire support and helicopter control. The radar is
