The new generation Gripen will be equipped with sensors that can detect low-radar-cross-section (RCS) targets, and will provide the pilots in a Gripen formation with a new level of situational awareness, says Bob Mason, Selex-ES marketing director for advanced sensors.
According to a report in the Aviation Week, Gripen E will have three Selex-ES sensors and a new identification friend-or-foe (IFF) system with three electronically steerable antenna arrays, which matches the radar's range and field of view.
Mason describes that the IRST is capable of detecting low-RCS targets at distances compatible with a beyond-visual-range missile launch. Confirming that the Selex IRSTs have tracked low-RCS targets, he says, “We have seen them.”
The report adds that Selex IRSTs have undergone a lot of changes, the most important one is the development of algorithms, based on operational experience and the analysis of real-world imagery, that look at IR signatures in detail, including variations of color and brightness within the target, in order to filter out false alarms caused by everything from birds to barbecue grills.
“The IRST can give the radar a very accurate azimuth and elevation to the target, which allows it to focus its energy and increase the probability of achieving detection and track on a low-RCS target,” Mason says.

Production of the new Gripen is done primarily in Linköping and work is already in full swing. Test flights, where critical subsystems and their interoperability are tested to minimise risk, are already well underway. First delivery is planned for 2018. As previously reported, development is proceeding according to plan and contracts have been signed with all major subcontractors.
One of our engineers tells her story.
Saab successfully performed the first flight with the new sensor IRST (Infra Red Search and Track) which will feature in Gripen E, according to schedule this year. The IRST does not emit a signal and can, without revealing the aircraft’s own position, silently detect, track and identify all types of targets.
The IRST for Gripen E is produced by Selex in Scotland and is called Skyward G. It is a passive sensor: it does not emit any energy but only listens for energy coming from other sources.
“The first flight in the Gripen E test aircraft with IRST has been performed with very good results. Multiple targets were detected, tracked and identified and the system works perfectly as expected. IRST is a new sensor on Gripen, which allows pilots to see great distances in several directions,” says Saab’s Wing Commander Flying Hans Einerth.

Recently, aviation magazine AFM took a closer look at the history of Gripen and the factors that keep it ready to meet the future challenges. AFM paid a visit to the Saab development facility in Linköping and talked to Björn Johansson, the chief engineer on the Gripen E/F project about the technology that goes into the development of the new generation aircraft.
According to Björn, when the SwAF looked at potential future threats, it came up with a list of requirements for a new aircraft, including the need for extended range; increased weapons payload and more hardpoints; a MIL-STD 1760E Class 2 weapon pylon interface and further adaptation to modern standards; an upgraded sensor suite with active electronically scanned array (AESA) radar; improved communication and fighter link including satellite communications (SATCOM); an improved EW capability; a quick software-update capability; and a low life-cycle cost.
“The first thing we did was to find an engine that could do the job. It had to be powerful enough, cost effective, and reliable and fit in our existing airframe with reasonable modifications. We basically had two choices – the GE F414-400 or a modified RM 12. The choice fell on the F414, an existing and well proven engine (2.5 million-plus hours) with many of the safety features that were required on the RM 12 already implemented in the basic design. It has more thrust and approximately the same built-in centre of gravity [CoG] as the RM 12 in a similarly sized package. Some initial modifications were made to adapt ...

Hakan Buskhe, CEO of Saab, the company that sold the Gripen jets to Brazil, explains how education and the need to do more with less are key to the success of his company and his country.
Anyone arriving at Saab's offices in Stockholm, located on one floor of a small building without doormen, is shocked by the frugal atmosphere at what is one of the most cutting-edge companies in the armaments industry with almost 15,000 employees and which beat the Americans and the French to win a contract to supply Brazil with 36 fighter Jets – the Gripen NG, for Next Generation – at a cost of $4.5 billion. However, according to the 50-year-old company CEO Hakan Buskhe, it is this philosophy of simplicity which is behind Sweden's success. Before another trip to Brazil last week to meet with the commander of the Air Force and the minister of Science, Technology and Information, he granted us the following interview.
In 2009, when former President Lula announced that the government had chosen French jets to rebuild the Brazilian Air Force, what was the reaction like at Saab?
I hadn't joined the company yet, I arrived in 2010, but I heard that Saab executives and employees felt that the announcement by Brazil's former president came like a bolt of lightning out of a clear blue sky. It was totally unexpected, given their strong relationship with ...
"It is an opportunity for Brazil to reduce its dependence on technology in the industry. The choice of Gripen is the basis for the development of a Brazilian supersonic military aircraft," says Professor Abdalla Alvaro Martins, School of Engineering of São Carlos-USP.
In an interview in Noticias, Professor Martins talks about the opportunities that come with the Gripen Brazil contract in terms of sharing technology and co-developing a fighter aircraft with Sweden.
“More than technology transfer, it is important that Brazil could be a partner in the development of the aircraft. The Gripen NG is not quite ready. We can learn to design, modify and improve a combat aircraft.” Martins says.
Martins adds that depending on the agreement between Embraer and Saab, the partnership may result in benefits not only for military aviation, but also for civil aviation.
Another news report in Dinheiro also highlights that FAB’s agreement with Saab can put Brazil among the select group of countries that produce supersonic aircrafts.
The report adds that the Gripen contract is not restricted to just the import of aircraft but is much broader as it includes the development of Swedish - Brazilian military jets, which may even be sold to other countries.
The choice of Saab’s Gripen NG gives an impetus to the revival of the Brazilian defense industry, the report says.

Gripen has the world's most advanced military technology, says Muni Perez, a former Brazilian Air Force pilot in a report in canaltech.com.
Perez first talks about Gripen’s fly-by-wire system which enables everything to be controlled by a computer. For example, if the pilot gives a command to turn an aircraft, it goes through a computer first which analyzes if the aircraft can move safely at that time without damaging its structure.
A Gripen cockpit boasts of various advanced features including HUD, HMDS, multifunction displays and HOTAS. An HUD (Heads Up Display) helps a pilot to concentrate on flying the aircraft without having to look down for information. An HMDS (Helmet Mounted Display System), on the other hand enables the pilot to get all the information on the helmet itself, making it easier to focus on the mission even while looking outside the cabin.
The report adds that Gripen is made to be network connected i.e. it is in constant contact with other aircraft, stations and units on land and ships, sending and receiving data from sensors, radar and imaging through the DataLink system.
“Technology is constantly evolving. Saab provides an access to the source code of the system which makes it possible to upgrade the aircraft according to Brazil’s needs, and at a cost much lower than competitors,” the report says.

"To have a good surveillance capability, the possibility to move with the right equipment, to exact targeting will be very important in the future years, “says Saab CEO and president Hakan Buskhe in a video interview.
The video explores the biggest threats in the coming 10 years. The industry leaders talk about the threats as well as about the important capabilities for air forces to have in future.
Hans Einerth, Chief Wing Commander, Saab talks about what it is like to fly a Gripen and what makes the next generation aircraft unique.
“Gripen is a lovely plane to fly. The flight control system is simply terrific and the performance is outstanding. The next generation Gripen comes with a bigger engine that gives us better performance. It also comes with AESA radar that gives us the possibility to take targets farther away and also stealth targets,” Einerth says.
