Yelm Class 1917 Group 2
The Group 2 machinery was upgraded with geared turbines and more efficient boilers allowing the top speed to be raised to 34 knots. Armament was changed with the removal of the aft 3"/40 (12 Pdr) and the stand being enlarged to accomodate a pair of 3"/45 HA guns. The twin torpedo tubes were replaced with triples. While officially known as Yelm Class group 2, it is frequently referred to by many naval scholars as the Port Ludlow Class.
