Were the Type 41 Leopard and Type 61 Salisbury classes designed for a repeat of the Battle of the Atlantic?
Short answerTo an extent: they were built when planners still expected a major war could remain conventional and last long enough to require a large escort force.
NotesThe Type 41 and Type 61 frigates belonged to a period when planners expected a war with the Soviet Union could remain conventional and last long enough to require many escorts. The comparison offered is with the reluctance of European powers to use their chemical and biological stockpiles against one another during the Second World War. Fear of retaliation could keep such weapons unused even during a major conflict. The argument then turns to conventional force cuts: reducing the means of fighting conventionally leaves leaders with fewer options before considering nuclear weapons.
