Spain is in a moment of weapons renewal. A few days ago we said that the country has been selling his old submarines for scrapa movement conditioned by something very specific: the new generation of S-80 submarines is beginning to gain traction. Or impulse, rather. And the ignition of engines S-82 Narciso Monturiol It is one more step towards delivery to the Navy.
And it has cost…
Milestone. It was last February 28 when S-82, the second submarine of the S-80 Plus series, started its diesel engines for the first time. The Ministry of Defense has become again echo of the achievement achieved a few weeks ago, and it is no wonder. The ignition is one more step in the commissioning of the submarine after the electrical ignition, the boarding of the batteries and the launching. Overcoming these phases brings the ship closer to its delivery.
The S-82. The Narciso Monturiol measures about 80 meters in length, has about seven meters in diameter and is capable of moving about 3,000 tons while submerged. It has capacity for more than 30 crew members and can last submerged for three weeks.
Regarding weapons, account with a system developed by Navantia and Lockheed Martin that allows launching ground attack missilesbeing the only of the European Union’s conventional submarines that have that capability. It can also arm DM2A4 heavy torpedoes with a range of up to 50 kilometers.
Issues. And if the ignition of the engines is announced as a milestone, it is because the S-80 program has not had it easy. These are the first submarines of Spanish design, and since 2004 they have been suffering delays. The first in the class, the S-81 Isaac Peralshould have been delivered in the early 2010s, but design errors and a budget that went from 1.8 billion euros to 3,900, ended up being delivered in 2023.
The biggest problem was weight, something crucial in a submarine. It had between 70 and 100 tons of overweightsomething that was discovered just when it was due to be delivered and that compromised the entire project because it is something that would cause buoyancy problems. There were also other problems in the propulsion system and disputes between the Spanish Navantia and the French Naval Group.
Next steps. And, again, completing these tests is the step prior to delivery at some point this year. It also shows that there is someone doing the calculations somewhat regularly because the S-82 was scheduled to be delivered at the end of 2024, generating a delay in the plans. This delay is what caused the very veteran S-71 to have to be revised so that Spain could keep two submarines operational at the same time, giving itself the situation of having a new generation one alongside the aforementioned S-71.
The next steps for the S-82 are to continue testing systems before delivery, and then the S-83 and S-84 will arrive, which were dated for 2026 and 2028 respectively and will arrive with a novelty: the BEST AIP system to improve immersion capability and long duration missions. Both the S-81 and S-82 will also be upgraded with the BEST AIP at some technical stop between 2029 and 3031, respectively.
After that ignition of the S-82 engines, they start the most critical tests, such as those of acoustic signature and immersion, key steps before it can be launched into the sea to definitively retire the S-71.
