In October 2009, Saab proposed to replace the Swedish Air Force's Sk 60 trainers with the Embraer Super Tucano. In March 2014, the Swedish Air Force publicly acknowledged that it was to begin studying replacement options for the Saab 105; Major General Micael Bydén observed that multinational training opportunities were being examined and that prospective replacement aircraft include the Alenia Aermacchi M-346, BAE Systems Hawk and Pilatus PC-21. On 28 March 2014, Saab and Pilatus Aircraft signed a memorandum of understanding to offer the PC-21 to the Swedish Air Force. On 29 April 2015, a request for information (RFI) was issued by the Defence Materiel Administration (FMV) for a new Military Flying Training System to provide long term basic and advanced training fleet functions; the advanced trainer requirements specify the presence of an embedded training capability including simulated radar and weapons use, as well as tactical displays in both cockpit positions resembling fourth and fifth-generation jet fighter aircraft.
