I think both SAAB's own estimates and claims from the recent Slovakian purchase re: op costs for Gripen and F-16 should be taken with a grain of salt.
EVERYTHING has to be taken with a grain of salt.
Vendors ALWAYS tell lies, big and small, uphill and downhill.
Who's to say that having a swarm of F/A-50s with some form of BVR and backed up by airborne radar platforms isn't the right way to go?
Myself, for one.

See below.
Launch and land from a distance instead of trying to tangle with J-11s. 
But which BVRAAMs would those be?
You can only shake wut ya momma gave ya...
Same applies to PGM's for moving sand or spearing fish, and besides, you might have to
rethink what OPFOR air would likely be trying to do, and what PAF would be trying to do,
if actual shooting ever broke out, and the conditions under which shooting would begin.
Try to rethink who would be the one
forced to enter the other's AD sphere.
As for the lack of "daylight" between a putative 39 C/D and a 50, I offer a different argument for the
acquisition of the 39 as a weapons platform... why not use the 39s as a dedicated maritime strike or
anti-shipping platform? They have the necessary AAR/IFR capability the current crop of 50s lack. They
also bring the requisite sensor and payload capacity expected of a dedicated maritime strike platform.
They also bring a built-in capability in the RBS-15 missiles instead of having a missile system integrated
on whatever platform we own/buy...
I prefer to think of it this way... the FA50s would act as our Mirages(lol), while the JAS-39s act as our
pissed-off, Exocet-slinging Super Etendards(lolol).
Okay, but you're not changing the level of pain, so much as redefining its purpose, and I
suspect many can point out that there are acquisition/sustainment-cheaper alternatives
as AAR-kitted AShM platforms: the runts of the litter perhaps being those mothballed AM
AMX pitched at PH awhile back (theoretically cleared, or at least successfully-evaluated
for Marte ER and Exocet). There are certainly more capable options that still cost so much
less (lifecycle) than 39, because most of them are EDA.... but I'm rambling now.
With your leave, m...
[soapbox]
We were (correct me if I'm wrong) talking about maritime strike, or worse, interdiction?
In like tone as my caution to Mr.S... just
whose AD bubble is this all taking place in?
What possible, effective role for a 'swarm' of AAR-illiterate, heater-only FA-50PH, then?
That far out to sea (or rather, that far into OPFOR AD), it's all on the AAR-fluent PGM-slinger.
Does ^that not then prescribe true, fully-capable MRF?
It still wouldn't be enough, no? Given the domestic EWR picture, even Viper is a limp dick.
We'd need true MRF operating within
a true AD-defeat system, which we can't afford.
It's something 99% of the nations upon God's green earth can't afford.
That's why, in that context again, we'd sorely need our MDT ally's superpower support.
PAF assets will have crucial roles to play, interoperating with the US in an MDT situation.
PAF assets have crucial roles to play, precursive or preventive to an MDT situation.
PAF assets include platforms other than combat jets, and its the "other than" category that
will play the BULK of those crucial roles, keeping our Republic safe from her enemies.

Would that lack of 'daylight' between 39C/D and FA-50 get even more pronounced should KIA get a go-ahead from LM to build and sell a single-seat version of the FA-50 with AAR capability and maybe even CFT? FA-50's in that configuration forming the bulk of our tactical fighter squadrons and acting as a 'node' in a fully functioning IADS might not be so bad.
One can dream.
Until there actually IS such an FA-50 iteration in LRIP
man lang and available to PH,
dreaming is all ^that is,
'di ba?
I'd rather focus on what FA-50
PH can actually do, before gauging what a putative 'kuya'
(elder brother) MRF should be able to do. What did Marawi teach us about FA-50PH's CAS
and Strike limitations, and in a zero-AD environment no less? What do FA-50PH's real world
(PAF) and theoretical loadouts, its combat radius thereby, and above all, the state of and
prognoses for PH EWR, tell us about FA-50PH's limitations in *gasp* OCA or (okay, I'll play
along with the most common armchair-gaming) DCA or
kahit man lang maritime strike?
I've been deliberately talking about a '
sweet spot', and about '
pain', for a reason.
Tell me if a comfort zone is compatible with military readiness.
I do hope PAF gets AH-1Zs because, based on their reaction to the American F-16 'overture', that might be the only "Viper" they're ever going to fly. 
You're brutal. I like you.

I doubt there will be Zulus though.
