Passive Detection System, IFF
all-weather, carrier-based airborne early warning
and control (AEW&C) aircraft that patrols
task force defense perimeters
- Provides early
warning of approaching enemy aircraft and vectors
interceptors into attack position
- In addition to its
primary AEW function, can also provide strike and
traffic control, area surveillance, search and
rescue guidance, navigational assistance,
communications relay, and drug interdiction.
- Group II upgrade to
E-2C+ is the biggest advance in AEW technology in
- AN/APS-145 radar
provides fully automatic overland detection and
tracking and significantly extends the radar
detection limits. The radar capable of
detecting targets anywhere within a three-million-cubic-mile surveillance envelope while
simultaneously monitoring maritime traffic.
- An Enhanced
High-Speed Processor, which expands the active
track file by 400% over previous versions, is
incorporated into the mission computer. Each E-2C can maintain all-weather
patrols, track, automatically and simultaneously, more than 600 targets, and control more
than 40 airborne intercepts.
- Enhanced Main Display
Units provide operators with improved visual
- Joint Tactical
Information Distribution System (JTIDS)
incorporates several anti-jam features to allow
uninterrupted voice and data communications,
thereby enhancing interoperability.
- In service with Naval
Air Forces Atlantic and Naval Air Forces Pacific,
as well as the armed forces of Israel, Japan,
Egypt, Singapore, and Taiwan
- Will be delivered to
France in 1997
- Discussions with
several other potential customers are ongoing.
- The Hawkeye entered
service in 1961 as the E-2A and was updated in
1969 to the E-2B.
- E-2C was introduced
- In 1978, the
AN/APS-125 Advanced Radar Processing System was
introduced and was succeeded in 1984 by the
AN/APS-138 (now referred to as Group 0).
- Retirement has begun;
only 53 of these aircraft remain in the
- In 1988, Group I
version was introduced; this featured an upgraded
T56-A-427 engine, which eliminated operating
restrictions imposed by growth in the
aircrafts gross weight due to incorporation
of new systems.
- Radar was updated to
the AN/APS-139 with a High-Speed Processor that
doubled the track files maintained by the system.
- Eighteen Group I
aircraft were built and are being upgraded to
Group II configuration.
- The AN/APS-145 radar
alleviates saturation, track overload, and
overland tracking clutter.
- Group II increases
radar and IFF range, radar volume, target track
capability, number of targets displayed, and
target recognition capability through the use of
- Group I and Group II
aircraft are also referred to as E-2C+.
