However, with Spain's positive attitude to cooperation with Turkiye on naval platforms such as TCG ANADOLU (L-400) LHD and interest in further joint programmes, Abengoa, responsible for S-80 submarines' ethanol-based AIP system, might be an option. It is also known that companies such as ASPİLSAN and AYESAŞ have developed various AIP R&D projects. Establishing a stable development for MİLDEN's AIP system, whether fully local or partnership, is important to avoid programme delays.
Turkish Submarine MİLDEN's Construction to Start in 2025 | TURDEF
Chief of the Turkish Navy Ercüment Tatlıoğlu has stated that the construction of MİLDEN national submarines will begin in 2025.turdef.com
I thought we're going to cooperate with the Spanish but it seems like no final decision has been made yet.
To be honest, I'd rather they pursue a hygrogen fuel cell based AIP rather than an Ethanol based MEMSA type AIP, that is legit trash, its not efficient, the endurance is not great, and not as quiet as Fuel Cells.
I was under the impression that the Spaniards had a Hydrogen Fuel cell, but if they don't the MILDEN subs will end up being lower endurance and noisier with the ethanol based MEMSA design than the 214s being put in service right now.
There is also the issue with the engine, have you heard anything about where they are getting the engines from? Everyone seems to be using the MTU engines. The only ones I know that have something different are the French, everyone else using diesel subs is using German engines.
The only alternative to Germany than built their own engine is Japan, but thats a whole lot of politics over export restrictions.
