S74 Zobel, fast attack craft of the Federal German Navy
Seen here near Gourock on the Clyde during the Joint Warrier exercise of April 2015. The ship displaces only around 400 tons and has a crew of less than 40 but is a very capable warship, especially when compared to something like the Royal Navy's River Class patrol vessels. Zobel was decommission in 2016 and will be replaced in the 2020's.
