Radar is a legal necessity for the safe navigation of merchant ships, and within vessel traffic services is indispensable to the operation of major ports and harbours. Target Detection by Marine Radar concentrates solely on civil marine operations and explains how marine surveillance radars detect their targets. The book is fully illustrated and contains worked examples to help the reader understand the principles underlying radar operation and to quantify the importance of factors such as the technical features of specific equipment, the weather, target reflection properties, and the ability of the operator. The precision with which targets are positioned on the radar screen and with which their progress is tracked or predicted depends on how definitely they have been detected, therefore a whole chapter has been devoted to the issue of accuracy. The various international regulations governing marine radar are examined, a brief historical background is given to modern day practice and the book doses with a discussion of the ways in which marine radar may develop to meet future challenges.

A revealing study on the little-known and misunderstood provincial navies established by North American British colonists.

In The First Fleets, Benjamin C. Schaffer reveals how, contrary to widespread beliefs, the American colonies had a long tradition of independent naval defense decades before the Revolution. He demonstrates that Anglo-American governments established and maintained significant provincial naval forces and that the history of provincial navies illuminates broader aspects of colonial history and the colonies’ ultimate break with the British Crown.

Based on meticulous research, Schaffer recounts the sea-borne threats that American colonies faced from the French, Spanish, pirates, and others. He reviews colonial governance and the relationships between colonial governments and Great Britain. Highlighting Britain’s scant naval power in North America, Schaffer demonstrates how the vulnerable coastal colonies undertook their own self-defense.

Schaffer’s readable study offers many fascinating episodes from colonial history. Establishing a navy was controversial in pacifist-minded, Quaker-dominated Pennsylvania. South Carolina deployed its scout-boat navy to pursue enslaved Africans who fled colonial capture. The first paper money issued in North America was an initiative to pay for a naval expedition against French Quebec in 1690. These and other episodes show the intimate connection between these little-known provincial navies and the major sociopolitical developments of their day.

The First Fleets will be of great interest to historians and readers of early American history, particularly colonial maritime and naval activities. Readers interested in the political and military dynamics of pre-Revolutionary America, as well as enthusiasts of naval history and maritime trade, will find The First Fleets both a valuable resource and an engrossing narrative.

Engineering the battlefield—one armored advance at a time.

For centuries sailing vessels crept along the coastline, ready to flee ashore in case of danger or trouble; this worked well until weather or poor sailing drove these ships against an unforgiving coast. Saviors and salvors (often the same people) struggled to rescue both humans and cargo, often with results as tragic for them as for the sailors and passengers.

Joseph Francis (b. Boston, Massachusetts, 1801) was an inventor who also had the ability to organize a business to produce his inventions and the salesmanship to sell his products. His metal lifeboats, first used in survey expeditions in Asia Minor and Central America, came into demand among the world’s merchant marine, the U.S. Navy, and the U.S. Revenue Service. His corrugated “life car” was the keystone to development of the U.S. Life-Saving Service. Francis’s metal bateaux and lifeboats played an important role in the Third Seminole War in Florida. His metal pontoon army wagons served in the trans-Mississippi campaigns against the Indians.

In Europe, he was acclaimed as a genius and sold patent rights to shipyards in Liverpool and the Woolwich Arsenal in England, Le Havre seaport in France, in the free city of Hamburg, and in the Russian Empire. But while Francis was busy in Europe, Captain Douglass Ottinger, U.S. Revenue Marine Service, claimed to be the inventor of Francis’s life car and obtained support in the U.S. Congress and the Patent Office for his claim. Francis had to battle for decades to prove his rights, and Americans remained generally unfamiliar with his devices, thereby condemning Civil War armies to inferior copies while Europe was using, and acclaiming, his inventions.

In the eighties, the Royal Netherlands Navy acquired 15 minehunters of the Alkmaar-class. They were deployed worldwide in conflicts (the Red Sea, the Persian Gulf and the Libyan Sea). In all European waters they exercised and cleared historical ordnance. HNLMS Haarlem represents the rich history of the tripartite minehunters of the Royal Netherlands Navy.

The primary role of the Type 42 destroyers was providing air defense for the fleet. With their long-range sensors, the ships could also act as radar pickets, sailing ahead of a task group. HMS Southampton was the eighth ship originally destined to be a 16-ship class – two of these ships have been exported to Argentina. The type 42 comprised eight Batch 1 vessels, four Batch 2 and four Batch 3 Stretched Type 42.

After World War II, the Royal Netherlands Navy ordered new ships to counter the growing threat coming from the Soviet submarines. These ships were classified as ASW destroyers (onderzeebootjagers), but close to contemporary destroyers in terms of specifications. The national industry designed and constructed two classes of these ships. Drenthe was of the more capable Type 47B series.
