The British NS (North Sea) class non-rigid airships were the largest and last in a succession of blimps that served with the Royal Naval Air Service during World War I; developed from experiences gained with earlier classes to operate off the east coast of Britain on long-range patrols. Despite early problems examples of the class went on to break all flying records for non-rigid airships and the type became regarded as the most efficient of its kind.
