Had the same conversation @ ILA 2018 with a Belgian contact about the F-35 and the nuclear option as the Typhoon which is also being marketed to them, cannot carry bucket of sunshine.
Back to the Rafale debate - the Force de Frappe Air missions - they’re equipped with ASMP. For sure the Belgians contribution to the bucket of sunshine if they went for the French option will not include ASMp! And the Raale is not certified to carry the 61.
below is video of practice scramble for the nuke mission
