The TF50 marine gas turbine, which uses conventional marine diesel fuel, is coupled to a lightweight reduction drive and is driven just like a conventional diesel engine, from idle to full power and everywhere in between. Some of the current TF powered yachts use only turbine engines, with no diesels on board. Either way, the result is the same, a tremendous amount of power in a lightweight package and compact space.

The world’s first truly stealth vessel was recently launched powered by four TF™50A marine aeroderivative gas turbines in a Combined Diesel Or Gas (CODOG) turbine configuration. The Visby-class corvette, also known as the YS 2000 series, was designed and built by Kockums AB at the Karlskrona Shipyard in Sweden.

This flexible stealth vessel takes advantage of the TF50A’s high power density, low vibration and noise characteristics and ease of maintenance attributes. The TF50A engines were selected for this project based on the long successful performance history of the TF™ Series engines in U.S. Navy service and for the operational flexibility afforded by the twin turbine per shaft line drive concept. The small size of the TF engines coupled with the cantilever mount from the combining gearbox provides a lightweight, compact propulsion package well suited to the Visby’s design.
