Low Altitude Navigation and Targeting
Infrared for Night, or LANTIRN, is a system for use on the Air
Force's premier fighter aircraft -- the F-15E Eagle and F-16C/D
Fighting Falcon, as well as the Navy's F-14 Tomcat. LANTIRN significantly
increases the combat effectiveness of these aircraft, allowing
them to fly at low altitudes, at night and under-the-weather
to attack ground targets with a variety of precision-guided and
unguided weapons.
LANTIRN consists of a navigation
pod and a targeting pod integrated and mounted externally beneath
the aircraft.
The AN/AAQ-13 navigation
pod provides high-speed penetration and precision attack on tactical
targets at night and in adverse weather. The navigation pod also
contains a terrain-following radar and a fixed infrared sensor,
which provides a visual cue and input to the aircraft's flight
control system, enabling it to maintain a preselected altitude
above the terrain and avoid obstacles. This sensor displays an
infrared image of the terrain in front of the aircraft, to the
pilot, on a head-up display. The navigation pod enables the pilot
to fly along the general contour of the terrain at high speed,
using mountains, valleys and the cover of darkness to avoid detection.
The pod houses the first wide-field, forward-looking infrared
navigation system for Air Force air-superiority fighters.
The AN/AAQ-14 targeting
pod contains a high-resolution, forward-looking infrared sensor
(which displays an infrared image of the target to the pilot),
a laser designator-rangefinder for precise delivery of laser-guided
munitions, a missile boresight correlator for automatic lock-on
of AGM-65D imaging infrared Maverick missiles, and software for
automatic target tracking. For a Maverick missile, the pod automatically
hands the target off to the missile for launch with pilot consent.
For a laser-guided bomb, the pilot aims the laser designator,
and the bomb guides to the target. For a conventional bomb, the
pilot can use the laser to determine range, then the pod feeds
the range data to the aircraft's fire control system. The designator
is a four-digit PRF-coded laser that can designate for its own
weapons or for other acquisition devices or munitions. These
features simplify the functions of target detection, recognition
and attack and permit pilots of single-seat fighters to attack
targets with precision-guided weapons on a single pass.
The research and development program began in September 1980
with Martin Marietta Corp. [now Lockheed Martin, Inc.], Orlando,
Fla., as contractor. Initial operational test and evaluation
of the LANTIRN navigation pod was successfully completed in December
1984. The Air Force approved low-rate initial production of the
navigation pod in March 1985 and full-rate production in November
1986. The first production pod was delivered to the Air Force
March 31, 1987.
In April 1986, initial operational
test and evaluation of the LANTIRN targeting pod proved that
a low-altitude, night, under-the-weather, precision attack mission
was feasible. The Air Force approved low-rate initial production
in June 1986. Introduction of the LANTIRN revolutionized night
warfare by denying enemy forces the sanctuary of darkness.
Originally built for F-15E and
F-16C/D fighters, LANTIRN was modified for the F-14 to include
a global positioning system and an inertial navigation subsystem
in the AN/AAQ-14 targeting pod [the F-14 does not carry the navigation
pod]. The modification was ordered in response to a Navy decision
to phase out the A-6 carrier-based ground-attack aircraft by
mid-1996. The Navy has ordered LANTIRN targeting pods to equip
a total of 19 F-14 Tomcat Strike Fighters. VF-103, the first
Strike Fighter squadron which became operational in June 1996,
saw action in Bosnia and Iraq while deployed aboard the USS Enterprise
(CVN-65). The LANTIRN pods flew a total of 1,575 hours on 750
sorties, with a mission availability rate of 93 percent. This
LANTIRN upgrade is part of a broader initiative to add a ground
attack capability and other improvements to 210 F-14 Tomcat fighter
aircraft (53 F-14Ds, 81 F-14Bs, and 76 F-14As). The F-14As of
VF-154 on the USS Independence (CV 62), normally forward deployed
in Yokosuka, Japan, were equiped with LANTIRN prior to their
deployment to the Persian Gulf, as ar the F-14Bs of VF-102 on
the USS George Washington (CVN 73).
An upgraded software package,
installed beginning in 1999, for the LANTIRN pod allhws the F-14
to more accurately employ weapons as well as record more accurate
target coordinates. Using the Fast Tactical Imagery (FTI) system,
the F-14A Aircrew can transmit digital images captured from the
LANTIRN pod video to another Tomcat or to the Battle Group Commander.
These images could be used for immediate attack by another aircraft,
for damage assessment, for locating targets of opportunity, or
simply for determining precise coordinates for targeting by other
weapons.
The LANTIRN Bomb Impact Assessment
(BIA) Modification Program, formerly known as the Bomb Damage
Assessment (BDA) Mod Program, consists of detailed design, manufacture,
integration, and test of a radiometer, digital recorder, and
portable data transfer device with the current LANTIRN Targeting
Pod on F-15 aircraft. Software and hardware updates will also
be completed on associated support equipment and image interpreter
workstations. This modification would be done on existing LANTIRN
targeting pods with no degradation in current mission performance
and would be transparent to the pilot. A production/retrofit
decision will be made following successful completion of the
EMD program and authorization to proceed for retrofits of 43
Targeting Pods spread out over a three-year period. Delivery
of the first production LANTIRN BIA Pod is anticipated to occur
in January 2002.
The currently unfunded TESSA LANTIRN upgrade would integrate
a 3rd Generation Staring Array into the existing LANTIRN Targeting
pod. The upgrade will increase acquisition, identification and
weapon employment ranges by a factor of four over the current
1st Generation Scanning Array in LANTIRN. This program will also
incorporate an Automatic Target Cuer (ATC) to assist the WSO/Pilot
in the detection and identification of targets in the viewing
area. The ATC will provide a limited target recognition capability
and display by class or vehicle type. The ATC performance is
enhanced by incorporating an IMU for sensor stabalization. The
upgrade improves standoff range (4-5 fold) for autonomous detection,
acquisition, and attack of Time Critical Targets. It provides
a higher probability of first-pass acquisition and attack of
unsheltered mobile targets, enhances target re-acquisition following
target hand-off from off-board sensors, and provides increased
all-weather target acqusition , identification and assists in
defeating passive CCD. |
