The Z rocket was an anti-aircraft weapon developed in Britain in the Second World War and launched in numbers from projectors. Although it was not very accurate it was thought that, if fired in sufficient numbers, some success might be achieved. In April 1941 the first German plane was brought down by one, part of a battery defending Cardiff. Later
developments linked it to radar and equipment that could forecast aircraft flight paths.
Land-based batteries, known as Z batteries were usually operated by the Home Guard. They comprised 128-round launchers.
There follows a favourite clip from 'Dad's Army', a comedy series based on the Home Guard.
