Development History
The Gripen E's lineage traces back to the 1980s, born from Sweden's requirement for a cost-effective, multirole fighter capable of operating from dispersed road bases as part of its Cold War defense doctrine. The original JAS 39 Gripen A first flew in 1987, followed by the upgraded C/D variants in the late 1990s, which introduced NATO interoperability and enhanced avionics. The decision to develop the "E" variant, initially known as Gripen NG (Next Generation), was driven by the need to counter evolving threats and integrate 5th-generation technologies without incurring the massive costs of a completely new design. Saab officially launched the Gripen E program in 2007, focusing on a more powerful General Electric F414G engine, an active electronically scanned array (AESA) radar, increased fuel capacity, and enhanced weapon payload. The first Gripen E demonstrator flew in 2008, with the first production-standard aircraft taking to the skies in 2017. Deliveries to the Swedish Air Force and the Brazilian Air Force commenced in 2019 and 2021, respectively, marking a significant milestone in its operational readiness. This iterative development approach allowed Saab to incorporate advanced features while leveraging existing Gripen infrastructure and expertise.
