Yeah, I corrected myself but I was too late,
You continuously talk about areas you simply don’t know much about. No offense.
But Fateh is a weird case, why weren't more of it built is a mystery but it points to a structural problem.
Again more incorrect analysis. Fateh is a new project there are 3 being built with 1 in service already.
Building submarines takes time especially on a restrained military budget.
I think it's the wrong size for Iran's needs anyway,
Based on what? your extensive experience in naval warfare?
Fateh is a sub made for PG/the opening of the Arabian sea. It’s an area denial weapon. It’s a perfect weapon as it’s a quiet diesel submarine that can lay mines and fire stand off anti ship missiles at battle fleets.
I think iran needs something around 1.000 tons..
Yeah it’s called the Besat project. Look it up. Will be 1300 tons. There are two types of subs Iran builds, ones for defense of PG and the opening area and ones for blue water.
Blue water has lower priority at the moment as that’s mostly a power projection tool. It makes sense to build blue water submarines when you have a blue water fleet of ships. Iran has just started building (in last couple years) its first destroyer class vessel.
Smaller than Kilo but definitely bigger than
Kilo is 1,000 tons and Fateh is ~600 tons fully loaded and submerged.
There is no marginal benefit to a sub between these two displacements. Your commentary is all over the place like usual.
It needs to be able to patrol the arabian sea while remaining submerged.
These submarines don’t “patrol”. They are warfare submarines. They are deployed to prevent conflict or engage enemy warships and lay mines in case of war.
Nonetheless Fateh can “patrol” Arabian for up to month. Which would mostly be training and intelligence gathering purposes as there is no point in a submarine patrolling these waters at the current moment.
And critically, Iran doesn't have AIP technology which is a huge issue.
No it is not. Fateh submarines can stay at sea for 35 days. That is plenty of time to inflict damage in case of conflict with US. Iranian coastline is littered with coves and inlets. Iran also has underwater sub bases. So refueling and hiding advantage goes to Iran.
Reverse engineering the stuff others make doesn't make you top 5 in the world, there's nothing original and it's doubtful if you can make the same quality.
Clearly you are not informed. If we are talking about small arms. You don’t make “new” rifles as the number of new rifle designs that get widely adopted around the world is few and far between. It is unlikely you will invent something better than what already exists. Most of the world still uses derivatives of AK-47 for a reason.
So you improve the cost, reliability, performance, and optics of already said successful designs instead of reinventing the wheel.
