Created during WWII by the War Department, the Handbook on Japanese Military Forces was intended to familiarize command staff with nearly every aspect of Tojo's war machine. Originally classified "restricted", the Handbook was created from the best intelligence that the OSS and other military information sources could offer. It contains comprehensive information and analysis of the Japanese military system, and includes chapters on recruitment and training, field organization, tactics and fortifications. It also contains a description of Japanese insignia, uniforms and equipment. This includes discussions of mechanized forces and weapons from small arms to mortars, artillery, vehicles and tanks, as well as naval and land-based aircraft. Additional chapters describe the Special Forces and Military Police. While some of the details within this book may bear review in light of history, it remains one of the most comprehensive compendiums of information about the Japanese forces ever assembled. Although it was declassified after WWII, it's never been easy to obtain a copy of this book. This high quality reprint includes all the original text, diagrams and photographs from the final October, 1944 edition.

With the introduction of guided missiles to the U.S. Navy, the Gunner's MateMissile (GMM) rating was created. Tasked with operating, maintaining and repairing guided missile systems, the GMM had broad responsibilities. GMM training included two phases. GMM strikers studied for the Petty Officer 3rd Class rating (GMM3) and then advanced to 2nd Class (GMM2). From these candidates, some would be given additional training to obtain 1st Class (GMM1) or Chief Petty Officer (GMMC) ranks.This Gunner's Mate Missile M 2 & 3 manual was originally issued in 1972, when the Talos, Tartar and Terrier missile systems were in use. Chapter topics include an explanation of the Gunner's Mate (Missile) rating, how to hit a target from a moving ship, principles of missile flight and jet propulsion, missile guidance and control, launching systems, typical gun and missile systems, applications of servomechanisms, hydraulics and pneumatics, electrical devices, explosives / pyrotechnics and magazines, small arms andlanding party equipment and demolition, general maintenance, common test equipment and troubleshooting, launcher checks and missile replenishmentand servicing, and information input and output.

Created in 1946 as part of a 1,000 page Report on the Electronic Numerical Integrator and Computer (ENIAC), this ENIAC Technical Manual provides a fascinating glimpse into the technology behind the world's first electronic, general-purpose computer. Designed and built during WWII at the University of Pennsylvania, ENIAC was conceived by John Mauchly and J. Presper Eckert. It was financed by the Ordnance Department of the U.S. Army. The Army's intent was to use it to calculate artillery firing tables but ENIAC's digital, Turing-complete design meant that it could solve a wide range of problems. Eventually it was even used to compute data for the design of the hydrogen bomb. ENIAC represented a remarkable advance in technology. Its speed was 1000x faster than the electro-mechanical machines that preceded it, and it relied on no moving parts to produce calculations. Famously, the ENIAC contained almost 17,500 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors and 10,000 capacitors, and took up nearly 1800 square feet while consuming 150 kW of power. While vacuum tube technology was not the most reliable owing to frequent burn-outs, the ENIAC operated roughly 50% of the time it was in service. ENIAC was composed of individual panels that performed different functions, with numbers passed between the units by buses. It could be programmed to perform a variety of now-familiar operations including loops, branches and subroutines, and could hold a ten-digit decimal number in memory. It even had the ability to branch - triggering different operations depending on the sign of a computed result - and could print results to an IBM punch card. Programming the ENIAC was not easy and often took weeks of work, some of it spent mapping out the problem and much of it spent settingup the computer's numerous switches and cables. That task fell to several female programmers including the author of this book, Adele K. Goldstine. Created by the University of Pennsylvania in fulfillment of their contract, this ENIAC Technical Manual was originally restricted, and its publication limited to just 25 copies. Within its pages you'll find a complete explanation of the circuits of the machine. This text provides a unique and fascinating look into ENIAC, and is a must have for any student of computing theory and history. Please note: this book was made from an original mimeograph copy of the master typescript manuscript prepared in 1946. As a result some pages lack legibility.

The epitome of grace, beauty and design, the Supermarine Spitfire was one of the most deadly fighters of WWII. Manufactured in huge numbers - over 20,000 were built - the Spitfire was the only fighter airplane in production at thebeginning of WWII, that remained in production after the conflict. Many different variants were produced including the Seafire naval fighter. Nineteen Spitfire squadrons were available to the R.A.F. by the fall of 1940, when the Battle of Britain began in earnest. While the Hurricanes attacked Germanbombers, Spitfire pilots were most often tasked with engaging Luftwaffe fighters. With its superior maneuverability, the Spit proved more than a match.These pilot's notes for the Mark IIA and IIB were standard issue for R.A.F. pilots circa 1940. They contain information about aircraft operation, controls, handling and maneuvering, and emergencies. (An enhanced 8x10 edition is also available featuring ground crew maintenance and assembly information.)

The first monoplane fighter in the Royal Air Force, the Hurricane was designed by Sydney Camm in 1934 and first flew in 1935. A rugged,single-seat aircraft, the Hurricane was the first combat aircraft in theRAF capable of 300 mph in level flight. During the Battle of Britain,the Hurricane equipped more than three fifths of the RAF's fightercommand, accounting for 32 squadrons as opposed to just 19 for theSpitfire. While Spits took on fighters, the Hurricanes assaulted enemy bombers, forcing the Luftwaffe to use the Bf109 to protect its Bf110 escort fighters. Between 8 August and 21 September 1940, Hurricanes scored 1,593 kills out of the 2,739 total claimed by the British. The Hurricane's design evolved during the seven years (1937-44) itwas in production. Various versions of the aircraft flew as interceptors, fighter-bombers (sometimes called "Hurribombers"), in the ground support role, and for the Royal Navy as the Sea Hurricane. More than 14,000 were produced. Created by the R.A.F., these pilot's notes for the IIA, IIB, IIC, IID and IV aircraft were standard issue in 1940 They contain information about aircraft operation, handling, and emergencies.

North American's A-5 Vigilante served for nearly two decades as an all-weather supersonic strike aircraft and reconnaissance platform. An outgrowth of studies begun in 1953, the prototype first flew in 1958. Originally designed to operate as a nuclear delivery system, the Vigilante was at the time of its introduction the largest and most complex aircraft to operate from a carrier. Carrying a crew of two, the Vigilante was equipped with two General Electric J-79 turbojets, and utilized a single tailfin. It featured a high-mounted swept wing with aluminum-lithium alloy skins and no ailerons. The Vigilante featured cutting-edge technology and was one of the first aircraft to use fly-by-wire systems and a heads-up display, as well as inertial navigation among other advanced systems. The Vigilante's bomb bay was located between the aircraft's engines, giving it a streamlined appearance and making the large aircraft surprisingly agile. As a result of shifts within the Navy's nuclear strategy brought on by the advent of the nuclear ballistic missile submarine, the A-5 never served in a strategic role. Instead most were converted to the RA-5C reconnaissance platform. Beginning in 1964, Vigilantes flew missions in Vietnam. Although extremely fast and maneuverable, the RA-5C's combat record was far from stellar. Difficult and expensive to maintain in the field, the Vigilante also compiled a dubious loss record. Out of 156 built, 18 aircraft were lost in combat and nine more succumbed to accidents during the Vietnam conflict. After 1974, a phase out of the Vigilante began with smaller, less complex fighter aircraft taking on the recon role. The RA-5C was deployed for the last time in 1979.Originally printed by the U.S. Air Force, this A-5A Vigilante flight operating manual taught pilots everything they needed to know before entering the cockpit. Originally classified "Restricted", this manual was declassified long ago and is here reprinted in book form.
