* - Flotilla Leader

1:600 "G" class. They were shorter and beamier than previous ships due to addoption of side fired boilers. © Andrew Arthur.
HMS Griffin with wartime modifications. A 12pdr. AA gun replaced the after torpedoes, "Y" gun was removed to carry extra DC's, "A" gun was replaced by a hedgehog, and 20mm AA were the light gun fit. © Andrew Arthur. SW.272 was carried at the bridge head, and the after funnel was cut down. © Andrew Arthur.

As a result of ongoing weight and space-saving developments, this class returned to the smaller dimensions of the "A" class but with a larger beam to allow for one single and one double boiler room.
They carried two DC throwers and one rack for 20 DC's, and a prototype of quintuple tubes was fitted to the Glowworm although bunkering had to be reduced to alllow for it.
The leader had a Yarrow side-fired boiler and so was actually 13 feet shorter although again beamier.
All carried a tripod masts fore and aft.
All surviving units ( not Grenville and Gipsy ) replaced the after tubes with a 12 pound AA gun, lost the mainmast, carried AW type 286 RDF on the foremast and had the after funnel shortened.
Garland and Griffin, the only survivors replaced "Y" gun with more DC throwers and stowage, had the multiple MG's removed, four 20mm Oerlikon cannons added. Also Griffin replaced "A" gun with a hedgehog, and had SW type 271 RDF replacing the LA.DCT, no 12 pounder, extra depth charges and four more Oerlikon cannons.
