In the article the loadout information seems incomplete, not mentioning a lot of the munitions that you would expect it to use, it concentrates on the lgb side of things:
During Torpedo Focus and Green Flag West, RAF Typhoons carried stores and weapons in one of three configurations.
» General ‘dry’ fit – two under wing fuel tanks, a Litening III targeting pod carried on the centreline station, and no weapons.
» Self-designation attack – a Litening III targeting pod carried on the centreline station, and up to six Paveway II laser-guided bombs.
» Co-operative attack – a fuel tank carried on the centreline station, and up to six Paveway II laser-guided bombs.
if it takes 2 wing tanks and a tgp then it can "only" take a maximum of four 1000lb bombs with a few spare stations for a-a missiles, which is pretty good for a multirole fj.
i would expect the current default loadout to consist of at least 2 wing tanks due to the way conflicts are going, in order to maximise time on station, plus how often are more than eight 1000lb bombs required by a 2 ship CAS flight?
im guessing that they were testing the Paveway II rather than the III for economic rather than capability reasons?
