Radar Warning Receiver
Gripen is built for high survivability in a combat environment. Gripen tactics are based on smart use of a variety of electronic warfare capabilities. The RWR (Radar Warning Receiver) is the source for an accurate sensor for detecting emitting threats such as radar.
Missile approach warning system
Gripen E has a sophisticated Missile Approach Warning (MAW) system. The MAW system uses passive sensors and can detect and track incoming missiles of all types! Not only radar-guided missiles but also passively guided IR missiles can be detected and the correct defensive actions taken.
Gripen is a survivor. There are many reasons for this, one of them being the fact that it can carry a vast number of chaff packets and flares – substantially more than many competitors. For the Gripen E, this ability is further enhanced with an even greater number of chaff, flares and pyrophoric chaff – so called hot chaff.
If ever attacked, a Gripen pilot can rely on the strong protection provided by all the defensive countermeasures released, tricking incoming missiles to change their course.
Survivability and countermeasure summing up:
- Effective system awareness with
- AESA Radar
- EW system
- RWR – Radar Warning Reicever
- MAWS – Missile approach warning system
- Large amounts of countermeasure dispensers
- Chaff, hot chaff, flares in pre-programmed sequences
The Gripen project has quietly built momentum since it began in the early 1980s and now stands as arguably the most promising export-oriented combat aircraft programme in the world, says Angad Singh in an exclusive report on the fighter aircraft which featured as the cover story “The Gripen Forges Ahead In Super Mode” for the May-June issue of the Vayu magazine.
Gripen made its first flight in December 1988, and the first production aircraft was delivered to the FMV in 1993. In total, Sweden had ordered 204 fighter aircraft which were delivered in three batches. Though the first batch was delivered under a fixed price contract, Saab and FMV agreed on a ‘target price’ concept for the second batch. Taking it even further, the third batch was delivered in 2008 at a cost that was 10 per cent less than the agreed-upon price, impressively increasing the efficiency of the programme.
For Gripen’s new variant, Saab and its partners have invested heavily in cutting edge technologies such as gallium nitride (GaN) for sensors such as AESA radars and electronic warfare (EW) systems. Selex Skyward-G infrared search and track (IRST) sensor and a new IFF (identification friend or-foe) system have added to the buzz around Gripen E development.
The Gripen E test aircraft which has already shown its supercruise ability in 2009, has logged around 300 flights ratifying its vital systems and airframe attributes and generating unprecedented interest across the globe.

Gripen E represents that rarest of capability improvements, one that does not come with a correspondingly hefty price tag, says Angad Singh in an exclusive report on the fighter aircraft which featured as the cover story “The Gripen Forges Ahead In Super Mode“ for the May-June issue of Vayu magazine..
Gripen E development, right from the start has been focused on producing an aircraft that combines high performance and low cost. For example, GE F414 engine, with its high performance and reliability was the obvious choice for the new generation aircraft. Also, sensor development for Gripen E focuses on leveraging a mix of innovative solutions and proven technologies which eventually keep the cost down.
Gripen E would have sensors that are enhanced, not just in comparison to its earlier variants, but also to contemporary fighters worldwide. It would also feature GaN-based EW suite that provides tremendous situational awareness and BriteCloud which is an onboard active decoy from Selex.
All this, according to the report, results in an aircraft that looks much the same – and feels much the same – but brings a quantum leap in performance and combat ability to the type.
Saab has not only drawn on its experience from the Gripen A/B to C/D conversion programme, but also on industry best practices acquired from manufacturing work done for Airbus and Boeing commercial products.
More emphasis on pre-production design work has led to reduced parts count for the new airframe, and shorter component manufacturing times, making each aircraft less ...
Gripen has a very moderate life cycle cost compared to its competitors. Life cycle cost equals acquisition cost plus operational costs during the entire lifetime. Flight hour cost is a parameter included in operational cost. When comparing these costs, it’s important to calculate with equal conditions, i.e. to compare “apples with apples”. An independent study based on open source ordered by Saab was conducted by IHS Jane’s with the following results:
Gripen has a considerably lower flight hour cost than its competitors. Some competitors are even several times more expensive than Gripen. There are three main reasons for this:
Cost consciousness from the start:
- Cost has always been a design parameter and Saab’s engineers are asked to maximise performance at a given cost, not just to maximise performance freely.
- Cost is a design parameter
- Maintenance and mean time between failure is part of the design variables
We select the best suppliers
- Saab is a systems integrator for Gripen
- For every system category, we look for the best price-performance, choose freely, and select the suppliers that best meet our high standards
Lean and model based development
- The models provide early design validation which reduces risk
- The models help engineers to visualise systems’ behaviour and thereby help avoiding misunderstandings
Cost Summing up:
- Cost is not something that is added later. It is built in from the very beginning “as a design feature”
- Gripen is breaking the cost curve
- Lowest life cycle cost on the market
The IRST for Gripen E is produced by Selex in Scotland and called Skyward G. IRST stands for Infrared Search and Track and is an electro-optical system mounted in the nose of Gripen E. Its sensor sits on top of the nose, just in front of the canopy, and is looking forward in a wide sector registering heat emissions from other aircraft, helicopters and from objects on the ground and sea surface. The IRST is a passive sensor, meaning that it never emits any energy. It only listens for energy coming from other sources. The tactical advantage of a passive sensor is that it will not give your position away. Opponents will have no indication whatsoever that Gripen E is using its IRST to monitor their activities.
IRST Summing up:
- Totally passive – nobody knows you are looking
- Senses heat from aircraft, tanks, ships
- Range can be many times more than visual range
- Enables silent attacks
Today at 21.45 CET, Saab will receive the honor of ringing the closing bell at the NASDAQ Stock Exchange in New York.
Saab’s listing on the NASDAQ OMX Stock Exchange, starting from the year 1998, has been instrumental in the company’s success and brand building.
The closing bell ceremony will be accompanied by a short film featuring Gripen, live at the Market Site Tower.
The ceremony is live, not archived, so it is important to watch in real time. Watch the closing bell ceremony and the short film livestream here tonight.
The joint Parliament and the Swedish Government Committee on Defence Policy's chairman Cecilia Widegren announced at a press conference that the number of Gripen Sweden intends to order has increased from 60 to 70 as per a new proposal, reports Expressen.
According to Widegren, besides the number of Gripen, the number of submarines has also been increased to five in the new proposal.
The Defence also wants the Swedish combat units to be more accessible and the Swedish Navy to be more active in the Baltic Sea. The new proposal aims to increase the cooperation with other countries and organizations like UN and NATO.
The proposal will be submitted to the government soon.

Gripen embodies engineering excellence, innovation and clever solutions by bringing together performance, cost-efficiency and industrial cooperation into one, smart fighter system.
Further to the decisions by the Swiss Parliament in 2013 to procure 22 Gripen E, a national referendum was held yesterday in Switzerland on the funding law for Gripen. The result was ‘no’ which means that the Gripen E procurement process in Switzerland stops. For Saab, the Gripen E programme continues according to plan, with development and production of 60 Gripen E for Sweden ongoing and deliveries scheduled for 2018.

With its balanced design, Gripen has an equally great a capacity to perform fighter, attack and reconnaissance missions. Fighter actions are against airborne targets such as aircraft, helicopters and drones. Attack missions are against land and sea targets. Reconnaissance missions gather information on specific geographic areas.
Low radar detectability is important, for instance, for combat aircraft developed with only attack capabilities - which most often means that customers pay in the form of lower acceleration power and manoeuvrability. Gripen is a true multi-role fighter aircraft in the sense that the pilot can switch between fighter, attack and reconnaissance when the plane is in the air. This can be compared with early multi-role fighters, when pilots had to determine the type of mission the plane would be performing before taking off.
