"R" Class Destroyer (1916)
A total of 62 destroyers of the "R" Class were completed in 1916-1917 as part of the War Emergency Programme.
There was a mix of Admiralty design vessels (39) and a diverse set of builder's specials (12 ships), and a refined Admiralty design (11 ships) that is sometimes referred to as the Modified "R" Class.[1]

In 1916, it was stated that "new destroyers" have two 26.25 kw dynamos arranged in parallel.[2] It is likely that this applied to this class.
Armament
4-in Guns
The first 51 Admiralty design ships and specials had three 4-in QF Mark IV guns on P IX mountings as in the preceding "M" class destroyers.
The eleven modified "R" class ships had three 4-in QF Mark IV guns on CP III mountings capable of 30 degree elevation, increasing extreme range by 20%.[3]
Other Guns
By 1920, some or all had one 2-pdr pom-pom for air defence.[4]
