Question: What class of submarines is based upon a class of diesel-electric attack submarines jointly developed by French Direction des Construtiones Navales and the Spanish company Navantia?
Context: The Sōryū"-class submarines (16SS") are diesel-electric attack submarines.  The first boat in the class entered service with the Japan Maritime Self-Defense Force in 2009.  The design is an evolution of the "Oyashio"-class submarine , from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders.  The "Sōryūs" have the largest displacement (ship) of any submarine used by post-war Japan. The "Los Angeles" class is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy.  The submarines are also known as the 688 class, after the hull number of lead vessel  .  They represent two generations and close to half a century of the U.S. Navy's attack submarine fleet.  As of 2017, 36 of the class are still in commission and 26 retired from service.  Of the 26 retired boats, 14 of them were laid up half way (approximately 17–18 years) through their projected lifespans due to their midlife reactor refuelings being cancelled.  A further four boats were proposed by the Navy, but later cancelled.  The class has more operating nuclear submarines than any other in the world.  All submarines of this class are named after American towns and cities (e.g., Key West, Florida, and Greeneville, Tennessee), the exception being USS "Hyman G. Rickover" .  This system of naming broke a long-standing tradition in the U.S. Navy of naming attack submarines for creatures of the ocean (e.g., USS "Nautilus" ). The "Heroj" class (English: Hero ) was a class of diesel-electric attack submarines built for the Yugoslav Navy during the 1960s.  The three strong class was the second generation of domestically built submarines, representing a significant improvement compared to the earlier "Sutjeska" class .  Built at the Brodogradilište specijalnih objekata (eng.  Special objects shipyard) in Split, the new class featured a streamlined hull design and four bow facing torpedo tubes that could also be used for minelaying. The "Virginia" class, also known as the SSN-774 class, is a class of nuclear-powered fast attack submarines (hull classification symbol SSN) in service with the United States Navy.  "Virginia"-class submarines are designed for a broad spectrum of open-ocean and littoral (shallow coastal water) missions.  They were conceived as a less expensive alternative to the "Seawolf"-class attack submarines, designed during the Cold War era.  They are replacing older "Los Angeles"-class submarine s, many of which have already been decommissioned.  "Virginia"-class submarines will be acquired through 2043, and are expected to remain in service past 2060.  Based on recent updates to the designs, some of the "Virginia"-class submarines are expected to still be in service in 2070. The Scorpène-class submarines are a class of diesel-electric attack submarines jointly developed by the French Direction des Constructions Navales (DCN) and the Spanish company Navantia, and now by DCNS.  It features diesel propulsion and an additional air-independent propulsion (AIP). The "Oyashio" class is a series of Japanese diesel-electric attack submarines operated by the JMSDF.  The submarines entered service in the late 1990s.  The submarines are larger than the earlier "Harushio" class , to provide space for a flank sonar array. The "Marlin"-class submarines are a class of diesel-electric attack submarine.  It features diesel propulsion and an additional air-independent propulsion (AIP), developed solely by the French company DCNS, formerly DCN, after the Spanish company Navantia (Formerly Bazan, then Izar), its partner in the Scorpène design, went with Lockheed Martin to build the competing S-80-class submarine , which was selected by the Spanish Navy to form its next-generation submarine force, at the expense of Scorpène. The S-80 Plus class (or "Isaac Peral" class) are AIP (air independent propulsion) submarines currently under construction for the Spanish Navy.  Four boats have been ordered, three of which are under construction by the Spanish company Navantia at its yard in Cartagena.  The submarines are being fitted with a new propulsion system designed for a high degree of autonomy under water.  Their mission includes: projection of naval power onto land, naval special warfare, surveillance, protection of naval forces and deterrence.  The first was planned to enter service in the Spanish Navy in 2015, with a second in 2016, but a weight imbalance issue has been identified which is to delay the project between 12 and 24 months.  The construction of the third in the series began in 2009.  The Indian Navy is considering this submarine for its next generation of submarines under Project 75I. The "Canberra" class is a ship class of two Landing Helicopter Dock (LHD) ships built for the Royal Australian Navy (RAN).  Planning to upgrade the navy's amphibious fleet began in 2000, based on Australian experiences leading the International Force for East Timor peacekeeping operation.  With a new climate for growing Australian Navy spending, a desire existed for forward defense capability for landing and supporting troops on Asian territory, that had never existed in Australian history, even with the old "Majestic"-class light fleet carriers, HMAS "Melbourne" and HMAS "Sydney" in the 1970s.  In 2004, French company Direction des Constructions Navales (DCN) and Spanish company Navantia were invited to tender proposals, with DCN offering the "Mistral"-class amphibious assault ship and Navantia proposing the ""Buque de Proyección Estratégica"" design (later commissioned as "Juan Carlos I").  The Spanish design was selected in 2007, with Navantia responsible for construction of the ships from the keel to the flight deck, and BAE Systems Australia handling the fabrication of the superstructure and fitting out. The "Kalvari" class is a class of submarines based on the Scorpène-class submarine being built for the Indian Navy.  It is a class of diesel-electric attack submarine which is designed by French "naval defence and energy" company DCNS and being manufactured by Mazagon Dock Limited in Mumbai.
Answer: Scorpène-class submarine
