S-81 Isaac Peral is not fitted with AIP.
S-83 Cosme Garcia, the third sub of the class, will be the first to run the BEST system. When it commissions in 2026.
Indeed. Re the S-80+ program:
The first, S-81 Isaac Peral, has already endured intense tests after its commission in 2023, including live torpedo launches recently at SINKEX-25. It has also taken His Majesty Felipe VI to maximum operational depth.
After partaking in DYNAMIC MARINER FLOTEX-25, the crew tied a broom to the sail when entering port, allegedly a sign for "we swept our rivals".
S-82 Narciso Monturiol will probably start sea trials this summer, to be commissioned around summer of 2026.
But S-83 Cosme Garcia, already sporting BEST, is now expected to be commissioned by 2028, and
S-84 Mateo Garcia de los Reyes, by 2029.
BEST AIP has been already fully tested in front of third parties (Indian Navy officers) and apparently results allow for some optimism, after such a strenuous development.
As for the submarine launched missile, it is to be the JSM-SL. Interestingly, confirmation was given recently by the Netherlands Prime Minister when announcing the missile selection for their Orka class submarine program.
I aimed for clean post, kindly ask for any particular and I will source a link.
Cheers!
