where do you install a laser pod? Because it's intensively used.
The LDP is only used for CAS, in which case you don't need the centerline tank on the EF anyway, since the CFTs alone hold 3000l, more than it carries today with external tanks!
Rafale in CAS would need 2300l in the CFTs + at least a supersonic fuel tank to be comparable.
No matter how hard you try, you can't negate the fact, that Rafales CFTs are not useful to replace external tanks, because the capacity is lower. Just as it is a fact that it can carry less Meteor, 1000lb bombs, or most A2G missiles (smaller than CMs), because of the advantages of the EFs weapons stations.
Rafale only on paper has many stations, but the 2nd pod station under the air intake, or the 2nd centerline station are useless and the external wingstations mainl meant for MICA, which so far no customer uses.
So as any fighter, it has it's pros and cons.
