Post war the Algerine class minesweepers were used in a dual role - also coastal escort with Squid forward of the bridge. This design was based on that layout but was cancelled due to budget cuts and concern over the metal hull with modern magnetic mines. The R.N.did later build a metal hulled minesweeper in the River class. This design was approximately 230ft in length, and featured a d.p 3-in/50 besides the single 40mm Bofors, and of course Squid forward with a sonar. I've based the drawing on Freidman's information, but I will probably modify for AU.
