40-509: A timid statement about what they actually had said resulted in accusations of reneging on their promise. Continuous studies done by FMV and Volvo Flygmotor AB (VFA) throughout the 1970s meant the candidates for what the new engine should be based on were quickly reduced to Pratt & Whitney F100 that would have resulted in an aircraft larger than the targeted 50%, or the smaller Turbo-Union RB199 and General Electric F404-400 that did not offer enough performance. FMV had informal contacts with

Blazon : "Fessed in blue and yellow; on blue three open yellow crowns placed two and one, on yellow two blue batons of command with sets of open yellow crowns placed two and one in saltire." Every time a new Chief of Defence is to be appointed, there is some debate between the different services. Some feel that some kind of rotational system would be appropriate. In actuality, most Chiefs of Defence have come from

100-828: The Army , and only one, Håkan Syrén , from the Navy . Because he is a general of the Amphibious Corps , there has to this day not been a single admiral to hold the office. Until 30 June 1994, the Chief of the Defence Staff was the second most senior member of the Swedish Armed Forces .

Several subsystems and components were also redesigned to reduce maintenance demands, including a modular design that split the engine into 7 distinct parts that can be replaced independently.

200-731: The Israelis who were looking for an engine for their IAI Lavi as well as with P&W. Rather than joining in for the P&;W PW1120, IG JAS went for the GE offer of an updated engine that had promise of low cost maintenance, the F404J. This engine featured a more resilient first fan, a slightly higher turbine temperature. The F404's analogue Engine Control Unit was replaced with the Digital Engine Control, jointly developed by Volvo and GE, which communicates with

220-475: The Ministry of Defence interfered at random to prove that they were keeping things in control. In an effort to get enough support for the JAS project, Saab had promised to cut the costs to the point where the previous Viggen was 50% more expensive than the new one. Somehow, this had been turned around into a promise to make the new aircraft 50% smaller than the 37, and that was where IG JAS found themselves stuck after

It was decided that GE would produce 65% of the engine and send it as a kit to VFA, who would manufacture the remaining 35% of the parts and be responsible for final assembly and testing. Produced by Volvo Aero, the RM12 is a derivative of the General Electric F404J. The fan was completely redesigned with thickened first stage blades which deform (causing
