Project history

Adventure was built under 1922 Programme as replacement for minelayer Princess Margaret. The first large ship built in Britain after the First World War. Many innovations have been brought in the design: for example, experimental machinery consisted of 2-shaft geared steam turbines sets (similar applied on cruisers of "C" and "D" types) on which shafts there were 2 2000hp electric motors. The electric power for them was produced by 4 diesels-generators with total 6600 kW power. Gases from diesels were deduced to own thin funnel standing end-to-end to the second main funnel. Diesel-electric propulsive plant was removed in 1941 as its funnel too.

Adventure became the first British ship with transom stern: it was supposed, that it will increase a propulsive efficiency but trials were found out, that mines can be attracted to a transom because of an arising zone of underpressure. It has compelled to rebuild in 1932 an aft end, having given to it more traditional "cruiser" outlines that has increased maximal length almost by 6m. Hull of Adventure in the plan had the same form, as Kent class cruisers: a trapezoid transferring to bulges below waterline. The short 25mm belt covered only machinery.

Protection

25mm belt and deck protected machinery only. There were bulges.
