The '''Ham class''' was a [[ship class|class]] of inshore [[minesweeper (ship)|minesweeper]]s (IMS), known as the Type 1, of the [[United Kingdom|British]] [[Royal Navy]]. The class was designed to operate in the shallow water of [[river]]s and [[Estuary|estuaries]]. ItAll tookof itsthe nameships fromin the factclass thatare all the ship namesnamed werefor British place names endingthat inend with [[List of generic forms in British place names|-"ham"]]. The parent firm whothat werewas responsible for supervising construction was [[J. Samuel White|Samuel White]] of [[Cowes]], Isle of Wight.
The class consisted of 93 ships, launched between 1954 and 1959. {{HMS|Inglesham|M2601|6}} (M2601) was the first. They were built in three slightly different sub-groups, the first sub-group, the 26-group, beingis distinguished by [[pennant number]]s beginning with 26-26xx, and the second and third sub-groups, the 27-group, beingare distinguished by [[pennant number]]snumbers beginning with 27-27xx. The 26- group werewas of composite construction (wood and [[non-ferrous metal]]s composite construction and the 27- group werewas of all-wooden,wood ofconstruction. which theThe third sub-group differedis bydistinguished havingby a prominent rubbing strake around the hull and slightly enlargedlarger dimensions.
The vessels displaced 164&{{nbsp;}}[[long ton|tons]] fully laden and were armed with one [[Bofors 40 mm gun|40 mm Bofors]] or [[Oerlikon 20 mm cannon|20 mm Oerlikon]] gun. They were {{convert|32.5 metres|m}} long overall bywith a {{convert|6.4 metres|m|adj=on}} beam. The construction was of wood to minimise 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 550at [[Horsepower#Brake horsepower{{convert|550|bhp]]|abbr=on|lk=in}} at 1,000 rpm, plus one 12YHAZ for pulse generation. Maximum speed was {{convert|14|kn|km/h}} dropping to {{convert|9|kn|km/h}} when mine sweeping.
The class shared the same basic hull as theirthe [[minehunter{{sclass2|minehunting]] counterpart, the [[Ley class |minehunter|Ley-class]]}} and the [[{{sclass|Echo class |survey ship (1957)|''Echo''-class]]0}} inshore survey craft.
