open-in-new
<h2 id="ships">Ships</h2> <p>The <i>Tridente</i>-class submarines are wrongly classed in the "diesel-electric" class. Their propulsion is exclusively electric, with electric motors powered by batteries. These batteries may be charged while submerged by "fuel-cells" (inverse electrolysis) for which, this submarine carries a huge supply of liquid oxygen and hydrogen. Also, and solely as a second solution for recharging the batteries, this submarine carries two powerful diesel-electric generators (1,000 KVA) for use only when surfaced, or at <a href="/facts/Submarine_snorkel/je7hKxVp">snorkel</a> depth. </p><p>Submerged, from <a href="/facts/Lisbon/zFTcC99e">Lisbon</a>, Portugal, submarines of the class may reach the <a href="/facts/Cape_of_Good_Hope/2gvK5uwP">Cape of Good Hope</a> and return, in 15 days. </p> <table><tbody><tr><th><a href="/facts/Pennant_number/1UvdSISw">Pennant</a></th><th>Name</th><th>Laid down</th><th>Commissioned</th><th>Status</th></tr><tr><td>S160</td><td><a href="/facts/NRP_Tridente/d0VDP7bn">NRP <i>Tridente</i></a></td><td>2005</td><td>May 2010</td><td>In service</td></tr><tr><td>S161</td><td><a href="/facts/NRP_Arp%25C3%25A3o/Wm9JlXNf">NRP <i>Arpão</i></a></td><td>2005</td><td>December 2010</td><td>In service</td></tr></tbody></table> <h2 id="image-gallery">Image gallery</h2> <h2 id="external-links">External links</h2> Wikimedia Commons has media related to Tridente class submarines. <ul><li><a href="http://www.marinha.pt/pt/amarinha/meiosoperacionais/subsubperficie/submarinos/submarinos209pn/pages/subsuperficie.aspx"><i>Tridente</i> class</a> <a href="https://web.archive.org/web/20160303192233/http://www.marinha.pt/pt/amarinha/meiosoperacionais/subsubperficie/submarinos/submarinos209pn/pages/subsuperficie.aspx">Archived</a> 2016-03-03 at the <a href="/facts/Wayback_Machine/nmQ3a6JC">Wayback Machine</a> information at the Portuguese Navy website (in Portuguese)</li> <li><a href="http://www.marinha.pt/pt/amarinha/meiosoperacionais/subsubperficie/submarinos/submarinos209pn/pages/caracteristicas.aspx">209PN profile</a> <a href="https://web.archive.org/web/20101111195314/http://www.marinha.pt/PT/amarinha/meiosoperacionais/subsubperficie/submarinos/Submarinos209PN/Pages/Caracteristicas.aspx">Archived</a> 2010-11-11 at the <a href="/facts/Wayback_Machine/nmQ3a6JC">Wayback Machine</a> at the Portuguese Navy website (in Portuguese)</li> <li><a href="http://arquivo.pt/wayback/20090525154402/http://www.areamilitar.net/DIRECTORIO/NAV.aspx?NN=28">Submarino de ataque (SSK) classe Tridente (tipo U-214) - <i>Área Militar</i></a>[<i>usurped</i>] (in Portuguese)</li> <li><a href="https://web.archive.org/web/20210828134443/http://www.areamilitar.net/analise/analise.aspx?NrMateria=42">Acquisition history of the U-209PN class</a>[<i>usurped</i>] (in Portuguese)</li> <li><a href="https://web.archive.org/web/20210211033708/http://www.areamilitar.net/analise/analise.aspx?nrMateria=15">Article about the differences between the U209, U212, U214 and U209PN</a>[<i>usurped</i>] (in Portuguese)</li></ul>
