Signals intelligence (SIGINT), or the collection of intelligence by the interception of communications or monitoring of other electronic signals, is the most productive source of intelligence available to governments and their defence establishments. In the Asia-Pacific region, there are moves to greater defence self-reliance. Throughout the region there has been a significant expansion of SIGNIT capabilities and operations over the past decade, and this is expected to continue over the foreseeable future. Signals Intelligence in the Post-Cold War Era describes these recent developments in global and regional SIGINT capabilities and operations, and provides some explanation for their developments.

In recent years the importance of Signals Intelligence (Sigint) has become more prominent, especially the capabilities of reading and deciphering diplomatic, military and commercial communications of other nations. This work reveals the role of intercepting messages during the Cold War.

SIGNALS INTELLIGENCE, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War.In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty’s famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers."SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." THE ST ERMIN'S HOTEL INTELLIGENCE BOOK OF THE YEAR AWARD 2014.

The following paper will examine the nature of the Soviet electronic penetration and the damage assessment of Soviet access to typewriters at the U.S. embassy in Moscow. This history of Project GUNMAN will also answer such questions as how the typewriter bugs were discovered and how they worked.

Presents a history of the agency, from its inception in 1945, to its role in the Cold War, to its controversial advisory position at the time of the Bush administration's search for weapons of mass destruction in Iraq, shortly before the invasion of 2003.

A comprehensive & authoritative history of the CIA's manned overhead reconnaissance program (MORP), which from 1954 to 1974 developed & operated 2 extraordinary aircraft, the U-2 & the A-12 OXCART. Describes not only the program's technological & bureaucratic aspects, but also its political & international context. The MORP, along with other overhead systems that emerged from it, changed the CIA's work & structure in ways that were both revolutionary & permanent. The formation of the Directorate of S&T in the 1960s, principally to develop & direct reconnaissance programs, is the most obvious legacy of the events in this study.
