The Type 216 is a submarine design concept announced by Howaldtswerke-Deutsche Werft based on the Type 212/214.^[3]

Development

The design is double hulled with two decks, includes a fuel cell, Permasyn motor, and lithium-ion batteries.^[2] It is a larger design targeted to meet the needs of the Australian Collins-class submarine replacement project, also known as SEA 1000, and the needs of other countries possibly including India and Canada.^[4] The Royal Australian Navy eventually chose the Shortfin Barracuda, a conventional variant of the French Barracuda-class submarine and no Type 216 was put in production,^[5] though this deal was later rescinded.^[6]

Successor

The AIP-equipped Type 218SG of the Republic of Singapore Navy is a modified design based on the Type 216.^[7] Four submarines were ordered by the Republic of Singapore Navy and the lead vessel RSS Invincible was launched in February 2019, followed by one more launched on 13 December 2022, with another two more under construction.
