Here are the specifications and some history of HMS Quickmatch. Specifications usually come from Conway's All the World's Fighting Ships 1922-1946 and Fleets of World War II by Richard Worth. Also supplemented by other references when available or needed. In this case Destroyers of World War II by Whitley
HMS Quickmatch 'Q' and 'R' class Destroyer Commissioned: September 1942 Decommissioned: May 1950 Displacement: 1,705 tons standard Length (OA): 358 ft, 3 in Beam: 35 ft, 8 in Speed: 36.75 kts Armament: 4 x 4.7 in QF (4 x 1), 4 x 2 pdr pom-pom (1 x 4), 6 x 20mm AA (6 x 1), 8 x 21 in TT (2 x 4), 2 x DCR (45-70 DCs)
Notes: Repeat of J class, but with only 4 x 4.7 in guns instead of 6, and 8 TT instead of 10.
I think it useful to tease out there that Establish Screen is in discussion for another unit in the pool for the British/Commonwealth. Between the two DD's, I think Quiberon had the superior career, and Raider and SubHunter are a nice pairing for any DD.
