Ordered by the Royal Navy in 1941, the destroyers of the 5th Emergency Flotilla became known as S-class and served as fleet and convoy escorts in World War II. In the last months of the war, three were transferred to the Royal Netherlands Navy for service in the Far East. HMS Serapis was renamed HNLMS Piet Hein and served in the Indonesian War of Independence and saw action in the Korean War. She was sold for scrap in 1962.

The ss 'Australis' was a well known ocean liner which entered service in 1940 as the
ss 'America' for the United States Lines. The ship was sold to the Greek Chandris Lines in 1964 and served until 1977 very succesfully on the route Western-Europe-Australia-New Zealand. Later the route became a full round-the-world-service. After her Australian period the liner sailed under the names of 'America' (for the third time), 'Italis', 'Noga', 'Alferdoss' and finally 'American Star'. In this volume of Liners the history of the great liner from when she was purchased by the Greek interest in 1964 until her sad wracking in January 1994.

This book provides an authoritative account of the current understanding of radar sea clutter, describing its phenomenology, EM scattering and statistical modelling and simulation, and their use in the design of detection systems and the calculation and practical evaluation of radar performance.

Sea Clutter: Scattering, the K Distribution and Radar Performance, 2nd Edition gives an authoritative account of our current understanding of radar sea clutter. Topics covered include the characteristics of radar sea clutter, modelling radar scattering by the ocean surface, statistical models of sea clutter, the simulation of clutter and other random processes, detection of small targets in sea clutter, imaging ocean surface features, radar detection performance calculations, CFAR detection, and the specification and measurement of radar performance. The calculation of the performance of practical radar systems is presented in sufficient detail for the reader to be able to tackle related problems with confidence. In this second edition the contents have been fully updated and reorganised to give better access to the different types of material in the book. Extensive new material has been added on the Doppler characteristics of sea clutter and detection processing; bistatic sea clutter measurements; electromagnetic scattering theory of littoral sea clutter and bistatic sea clutter; the use of models for predicting radar performance; and use of the K distribution in other fields.
