AEGIS is an american weapons system using radar and stuff jointly developed by japan america and UK (UK supplying parts and japan supplying computer equipment).
Also the spanish have only a small navy and i would personally see this as a first generation of home built submarine it looks alot like the french scorpene submarines being built now and if i remember correctly a licence was agreed between the spanish and DCNS so the spanish could build thier own scorpenes.
So id hesitate to say its all spanish as well.
On top of that the USA have limited fuel cell AIP knowlege or even use for this technology, you would be better off shopping for it in sweden or germany.
