The class consisted of 93 ships, launched between 1954 and 1959. {{HMS|Inglesham|M2601|6}} was the first. They were built in three slightly different sub-groups, the first sub-group, the 26-group, is distinguished by [[pennant number]]s 26xx, and the second and third sub-groups, the 27-group, are distinguished by pennant numbers 27xx. The 26-group was of wood and [[non-ferrous metal]] composite construction and the 27-group was of all-wood construction. The third sub-group is distinguished by a prominent rubbing strake around the hull and slightly larger dimensions.

The vessels displaced {{convert|164|LT}} fully laden and were armed with one [[Bofors 40 mm gunAutomatic Gun L/60|40 mm Bofors]] or [[Oerlikon 20 mm cannon|20 mm Oerlikon]] gun. They were {{convert|32.5|m}} long overall with a {{convert|6.4|m|adj=on}} beam. The construction was of wood to minimise the magnetic signature. The crew complement was 15, rising to 22 in wartime.

The engines of this class were [[Paxman (engines)|Paxman]] [[diesel engine|diesels]], some of which were built under licence by [[Ruston (engine builder)|Ruston and Hornsby]] of [[Lincoln, Lincolnshire|Lincoln]]. Each vessel had: two 12YHAXM (intercooled) for main propulsion, rated at {{convert|550|bhp|abbr=on|lk=in}} at 1,000 rpm, plus one 12YHAZ for pulse generation. Maximum speed was {{convert|14|kn}} dropping to {{convert|9|kn}} when mine sweeping.
