Scorpène-class

A Franco-Spanish diesel-electric attack submarine family with optional MESMA air-independent propulsion, exported to four navies and built under transfer-of-technology in India and Brazil.

Overview

The Scorpène-class is a conventional (diesel-electric) attack submarine designed by the French Naval Group (formerly DCNS) in partnership with Spain's Navantia. It forms the export backbone of French submarine industrial cooperation, with boats in Chilean, Malaysian, Indian, and Brazilian service. The design is notable for its low acoustic signature, a modular combat system, and the option of a MESMA (Module d'Énergie Sous-Marine Autonome) air-independent propulsion (AIP) module, which allows extended submerged endurance of more than three weeks without snorkeling. India's locally built Kalvari class and Brazil's Riachuelo class are the two largest Scorpène programs, both incorporating transfer-of-technology and indigenous content, while an evolved version was ordered by Indonesia in 2025.

Development

The Scorpène originated in the late 1990s as a joint development between France's DCN (now Naval Group) and Spain's Izar (later Navantia), aiming for a flexible, export-oriented SSK that could be tailored to customer requirements. The lead boat, O'Higgins, was built for the Chilean Navy at DCN's Cherbourg yard and commissioned in 2005, according to Naval Technology and Wikipedia. The design quickly attracted international interest, leading to licensed local construction programs in India and Brazil and direct exports to Malaysia. The program has since evolved into the "Scorpène Evolved" configuration, incorporating enhanced lithium-ion battery packs, a new sail, and an updated combat system, as seen in Indonesia's 2025 order.
