I've asked before, but the answer eludes me, but why don't we have more Ada-class Corvettes. If we had them with VLS like Pakistan's wouldn't we have more room to maneuver ? Is it the cost/pricetag ?
Would Ada class be able to sail all the way from Turkey to Libya without resupplying. I don't think the waters in Mediterranean would pose a problem.
No, not pricetag but capabilities!
There are 2 (main) matters
You have to see that Turkish defense industry made an enormous growth in the past 10 years.
When was Milgem developed? It started in 2008 (if I recal well), the tech level we had 13 years ago and now is not comparable anymore. When Milgem was being developed people did not even believe Turkey could design a warship. The designers had to fight against a mountain of taboos, convince not a few but whole Turkey that they could design a ship as good as western counterparts.
If we have to describe Milgem, I would describe it as a revolution that broke many taboos, close mindedness, low self esteem, doubts and vested prejudices. Despite that the designers achieved a miracle. Not only the Turkish people did not believe we could not make a good warship, so did foreigners. They were like "ah you have nice ambitions, but it's more than you can chew."
And now we have become so spoiled to criticise what was deemed impossible just 13 years ago, why was it not build with VLS, why not with own radars, why not with own engine.
Coming to your question of why we do not have more Ada-class corvetters, well we all remember that back 10 years ago Turkish requirement was for 12 Milgem class boats, but half way our navy must have realised once the Milgem was build we can build better, more armed. Milgem had grown the confidence that we could even design our own destroyer TF2000 (that began as let us assemble a foreign design as TF2000 and evolved into a full fledged 100% Turkish design).
Instead of Milgem the choice became like you say a milgem with VLS (I-class), as you know since now foreigners are aware that we can design kick ass battle ships we get all kinds of embargoes to slow it down, no VLS sales, no ESSM etc.
