JAS 39 Gripen is a single-engine multirole fighter manufactured by the
Swedish aerospace company Saab. It was designed to replace the Saab
35 Draken and 37 Viggen in the Swedish Air Force. Gripen is a new generation,
multi-role fighter aircraft which uses state-of-the-art technology.
It is capable of performing an extensive range of Air-to-Air, Air-to-Surface
and reconnaissance missions employing the most modern range of weapons.
Gripen is designed to meet the demands of current and future threats,
while at the same time meeting strict requirements for flight safety,
reliability, training efficiency and low operating costs. The Gripen
fighter is in service with a number of air forces: Swedish, Czech Republic
and Hungarian Air Forces and has also been ordered by the South African
Air Force and the Royal Thai Air Force. The UK Empire Test Pilots’
School (ETPS) is operating Gripen as its advanced fast jet platform
for test pilots worldwide. Gripen is NATO compatible and globally interoperable
meeting the most demanding operational requirements and has now accumulated
well over 100,000 flight hours. A two-seat version of the Gripen, which
retains the full operational capability of the single-seater, is also
available for tactical weapons training, more specialized missions and

JAS NG/IN:. Gripen NG is a true multi-role
fighter aircraft that has the operational range, payload
and built-in Net Centric Warfare (NCW) capabilities
to meet all roles as defined.
Gripen:. Saab has already completed
detailed design pre-studies for the Sea Gripen in response
to earlier interest from Brazi, Indial and other countries.
The performance characteristics of the basic Gripen,
together with the structural improvements of the Gripen
NG should allow the Sea Gripen to fit the Indian requirement.
It is capable of operating from carriers at a maximum
take-off weight of 16,500 kg and a landing weight (with
weapons and fuel) of 3,500 kg. For carrier operations
the aircraft is designed to have a service life of 8,000
flight hours, equally split between shipborne and land-based
world’s most agile fighter for close combat. A combination of
advanced aerodynamic layout utilizing a combined close-coupled canard
– delta configuration and a triplex, digital Fly-By-Wire Flight
Control System (FCS) leads to a winning Dog-Fight capability.
Saab ultimately selected a delta wing-canard design with relaxed stability.
The configuration provides for a high manoeuvrability along with better
takeoff and landing performance. The Gripen also has a low drag, enabling
it to fly faster, have increased range, and carry a larger payload.
The totally integrated avionics make it a "programmable" aircraft,
changing the software can provide for additional mission profiles. The
Gripen was designed to provide for a fast sink rate and hard, short
fully integrated avionic mission system operating on five 1553B digital
data bus highways. This provides total sensor fusion resulting in enhanced
combat capability guaranteeing precision delivery of smart weapons.
A combination of low radar, IR and visual signatures, along with the
long range PS05 multimode radar and sensor fusion, including world leading
new generation weapon integration, ensure a high kill ratio in long
The JAS 39 Gripen uses the modern PS-05/A pulse-doppler X-band radar,
developed by Ericsson and GEC-Marconi, which is based on the latter's
advanced Blue Vixen radar for the Sea Harrier (which inspired the Eurofighter's
CAPTOR radar as well). The radar is capable of detecting, locating and
identifying targets 120 km (74 mi) away, and automatically tracking
multiple targets in the upper and lower spheres, on the ground and sea
or in the air, in all weather conditions. It can guide several air to
air missiles at beyond visual range to multiple targets simultaneously.
JAS 39 Gripen is powered by a RM12 Engine supplied by Volvo Aero, is
a development of the GE F404 engine from General Electric. A digital
engine control system automatically monitors the engine parameters and
switches on the back-up systems if required. A condition monitoring
system registers the flight data.The JAS 39 The Gripen can fly at a
maximum speed of 2,470km/h. The combat radius and ferry range of the
aircraft are 800km and 3,200km respectively. Its service ceiling is
15,240m. The aircraft weighs around 5,700kg and its maximum take-off
weight is 14,000kg.
from recent conflicts has confirmed that operational requirements are
changing. Users of airborne platforms have also recognized this trend
and are themselves imposing appropriate demands on equipment and systems
suppliers. Users no longer want a specific aircraft for each operational
role. They require a multi-role platform that is capable of undertaking
all roles (Air-to-Air, Air-to-Ground, maritime strike and reconnaissance).
Gripen has been developed to meet a wide range of operational requirements
which include a variety of missions. The multi-role capability of Gripen
and its ability to change roles in the air at the press of a button
results in a unique swing-role, multi-mission flexibility.
To fulfill the various missions that Gripen could be asked to undertake,
the fighter has a variety of stores integrated and freedom of choice
when it comes to the nationality of the weapons supplier. The customer
has the choice to match Gripen together with stores from the United
States of America, Europe and other regions of the world, or from indigenous
The internally mounted 27mm Mauser high-energy gun can operate in an
automatic radar-guided aiming mode. The stand-off dispenser is the DWF39
from EADS (formerly DaimlerChrysler Aerospace) and Bofors. The Bofors
ARAK 70 rocket pod is cleared for carriage on the Gripen.
JAS 39 Gripen is fiited with 8 hardpoints, three on each wing and two
under fuselage, which can carry combinations of: Missiles: 6× Rb.74 (AIM-9) or Rb 98 (IRIS-T), 4×
Rb.99 (AIM-120) or MICA, 4× Rb.71 (Skyflash) or Meteor, 4×
Rb.75, 2× KEPD.350, or 2× Rbs.15F anti-ship missile. Bombs: 4× GBU-12 Paveway II laser-guided bomb,
2× Bk.90 cluster bomb, 8× Mark 82 bombs
advanced fully digital cockpit layout with three large colour, Multi-Functional
Displays (MFD) and Hands- On-Throttle-And-Stick (HOTAS) provide the
pilot with a superior combat advantage.
