The Porpoise class was an eight-boat class of diesel-electric submarines operated by the Royal Navy. This class was originally designated patrol submarines, then attack. They were the first conventional British submarines to be built after the end of World War II. Their design was, in many ways, influenced by the German World War II-era Type XXI U-boats.

  • Třída Porpoise byla třída diesel-elektrických ponorek postavených pro britské královské námořnictvo. Určeny byly především pro ničení sovětských ponorek v severním Atlantiku. Celkem bylo postaveno osm ponorek této třídy. Ve službě byly od roku 1958. Na svou dobu se jednalo o velmi vyspělou konstrukci. Ponorky byly velmi tiché. Jejich dalším vývojem vznikla úspěšná třída Oberon. Ponorky třídy Porpoise byly vyřazeny v letech 1977–1986. Důvodem byl nedostatek financí a potřeba posádek pro nové jaderné ponorky. (cs)

  • ポーパス級潜水艦 (Porpoise class submarine) とは、英海軍の潜水艦である。 独海軍のUボートXXI型の影響を受けた設計であり、在来型よりも水中行動能力の向上が図られている。船殻材にはUXWと呼ばれた新型鋼を採用し、可潜深度を増加させた。また、高性能な空気浄化装置により、潜航可能時間を増大させた。 キャビテーション抑制のため、新開発のハイスキュード・プロペラを採用したが、これによる推進効率低下により、最高速力は設計目標の18ノットから17ノットに低下した。だが、静粛性向上の利点は速力低下を上回ると判断され、問題とされなかった。 (ja)
