Editing Stirling engine (section)

====Submarine use====
In 1996, the Swedish navy commissioned three [[Gotland-class submarine]]s. On the surface, these boats are propelled by marine diesel engines; however, when submerged they use a Stirling-driven generator developed by Swedish shipbuilder [[Kockums]] to recharge batteries and provide electrical power for propulsion.<ref name="Kockums" /> A supply of liquid oxygen is carried to support burning of diesel fuel to power the engine. Stirling engines are also fitted to Swedish [[Södermanland-class submarine]]s, the [[Archer-class submarine]]s in service in Singapore, and the Japanese [[Sōryū-class submarine]]s, with the engines license-built by [[Kawasaki Heavy Industries]]. In a submarine application, the Stirling engine offers the advantage of being exceptionally quiet when running.{{citation needed|date=July 2020}}
