Book excerpt: Following on from the collection of successful ' Famous Russian Aircraft' titles, Yefim Gordon has teamed up with Keith Dexter and Dmitriy Komissarov to produce this insight into the Sukhoi fighter bomber family. In the early 1950s the reborn aircraft design bureau headed by Pavel O. Sukhoi started its renewed activities by creating two aircraft sharing the same fuselage design and powerplant – the delta-wing T-3 and the swept-wing S-1. The former became the progenitor of several interceptors, starting with the Su-9; the other aircraft became the Su-7 tactical fighter but soon evolved into the Su-7B fighter-bomber. Known to the West as the Fitter, the Su-7B and its improved Su-7BM and Su-7BKL versions formed the backbone of the Soviet fighter-bomber aviation. They were also exported to many "friendly nations" – first and foremost to some Warsaw Pact member states (Poland and Czechoslovakia), as well as to non-aligned nations like India, Algeria, Egypt, Iraq and others. The Fitter saw action in quite a few wars – the Indo-Pakistani border conflict of 1971, the Arab-Israeli wars. The initial Su-7 Fitter-A was superseded by the Su-17 which differed primarily in having variable-geometry wings. The prototype made its maiden flight in 1966; the production version completely supplanted the original Su-7 in Soviet Air Force service in the 1980s. The "swing-wing" Su-17 proved highly efficient in the Afghan War, earning the affection of the pilots who flew it. Its high combat capabilities were duly recognized abroad; apart from the Warsaw Pact (Poland, Czechoslovakia, East Germany, Hungary and Bulgaria), the Su-20 and Su-22 export variants were delivered to Egypt, Iraq, Peru, Yemen, Afghanistan and other nations. Iraq used its Su-22s against Iran in the war of 1980-88, and the ultimate Su-22M4 is still in service with the Polish Air Force – albeit with upgrades to make it compatible with NATO operational standards. This new title written by 3 aviation enthusiasts, including expert in the field Yefim Gordon, and is illustrated with a whole host of unpublished photos, as well as numerous line drawings and colour side views, which will undoubtedly be of interest to aviation enthusiasts and scale modellers alike. The "in service" and "operators" chapters feature insignia and unit badges/nose art worn by individual aircraft, making this a must have for any aviation and scale model enthusiast's collection.

Available in PDF, EPUB and Kindle. Book excerpt: Thorough Aerofax-series coverage is given here to the 'Fitter' family of Soviet fighters and fighter-bombers, with masses of fresh information and images emerging from previously unseen Russian sources. The Su-7 was first flown in 1958, with deliveries to the Soviet Air Force beginning in the same year. It could be seen as the Soviet contemporary of the F-100 Super Sabre. The original high-speed, highly-maneuverable single-seat fighter was developed in several versions and produced in large numbers for the VVS and Warsaw Pact countries during the 1960s. It was developed in the late 1960s with a completely new variable-sweep wing as the Su-17 fighter-bomber, again further modified during its long life to take on many other roles including reconnaissance, training and so on. The Su-22 was an export version of the Su-17, and the 'Fitter' family has served with many air forces in Europe, Libya, Peru, Vietnam and Syria.

Available in PDF, EPUB and Kindle. Book excerpt: As early as 1979, Soviet aircraft designers started work on a program called I-90, a fighter for the 1990s. Two Soviet aircraft design bureaus took on the task, Mikoyan and Sukhoi. Work began in 1983 but with the dissolution of the Soviet Union the project stalled. In 2002 the Russian government kicked off a new program under which Sukhoi began development of what was then known as PAK FA (Future Tactical Aviation Aircraft System). Known in house as the T-50, this aircraft strongly resembled the American F-22 Raptor in overall appearance. The first prototype took to the air on January 29, 2010 and in 2017 the fighter was allocated the service designation Su-57. In 2018 the aircraft had its combat debut when four of the prototypes were briefly deployed to Syria during the Russian campaign against the IS terror network in that country. Production was officially launched in May 2019, with the Russian Air Force having 70-plus on order. This work charts the development and trials history of the 1.44, Su-47 and Su-57, as well as other project versions that did not make it to the hardware stage. It is illustrated with numerous previously unpublished photos and drawings.

Available in PDF, EPUB and Kindle. Book excerpt: The Su-25 ground attack aircraft made its first flight on February 22, 1972. After five years of tests the aircraft reached its definitive configuration with new engines, a revised airframe and new armament, entering certification trials which were completed in 1981. A year earlier, however, the initial production Su-25 had received its baptism of fire in the Afghan War. Gradually the Su-25 became the progenitor of a family. The Su-25UB combat trainer came first; the single-seater and two-seater were also built for export as the Su-25K/Su-25UBK. A new line of development began in 1979 with a series of single-seat 'tank buster' variants based on the Su-25UB's airframe but featuring more advanced sighting systems and weapons. The first of these was the Su-25T of 1984, followed by Su-25TM (Su-39) of 1993 making the Su-25 in the end the sole Russian light attack aircraft. The Su-25 has been widely exported, serving with air forces in Europe, Asia, the Middle East, Africa and South America. Apart from the Afghan War, it has seen action in Iraq, Angola, Congo, Eritrea, Ethiopia, Macedonia, Côte d'Ivoire, Sudan and in conflicts between the former Soviet republics. More recently the Frogfoot has been used in the Russian participation in the civil war in Syria War. The book describes the full development and service history of the Su-25, featuring fleet lists and a design descriptions. It is illustrated throughout with numerous photos and color profiles.

Available in PDF, EPUB and Kindle. Book excerpt: The establishment of NATO posed the need for the Soviet war machine to create a fast jet bomber capable of reaching targets throughout Western Europe and combatting the carrier task forces with which the US Navy could throw its weight around the world. The basic Tu-16 which first flew in the mid-1950s was developed into nearly 50 versions adopted for various roles, including nuclear-capable bombers, anti-shipping missile strike aircraft, torpedo-bombers and minelayers, numerous reconnaissance and ECM variants, assorted development aircraft for testing new engines, avionics and systems. The Tu-16 even found civil uses as a fast mailplane and a weather research/rainmaking aircraft! The Badger, as the bomber was known to the West, served as the basis for the Soviet Union's first jet airliner, the Tu-104. The nearly 1,500 Tu-16s built in the Soviet Union were an important factor in preventing all-out military confrontation between the East and the West. Since the mid-1950s and until the 1980s the Badger has been a regular picture on the pages of the Western press, snooping around Western naval groups every now and then. The type also had its share of 'hot' wars, getting its baptism of fire in the Six-Day War of 1967. Apart from three factories in the USSR, the Tu-16 was built under license in China as the H-6 and remains in service with the People's Liberation Army Air Force. Other foreign users were Egypt, Indonesia and Iraq. All known versions are described and a full account is given of the Tu-16's operational career in the USSR and abroad during the Cold War and in the days after that when many of the surviving Badgers were used as target drones. The book features many previously unpublished photos and a detailed production list.

Available in PDF, EPUB and Kindle. Book excerpt: This volume details the technical features and operational performance of the Soviet Su-25 'Frogfoot', which proved itself as a durable and versatile attack aircraft in a variety of theatres such as Afghanistan, Georgia and Ossetia. Today it is widely accepted as the true successor to the types of specialised ground--attack aircraft that emerged during World War II. This book illuminates the service history of the 'Frogfoot' in over 30 years of combat using first-hand accounts and revealing archive photographs. The awkward-looking Su-25 has often been underrated, but the faithful 'Frogfoot' is now slated to remain in service with most of its current operators across the globe until at least 2020. This study explores the successes of the 'Frogfoot' in full, demonstrating its strengths as a formidably armed, armoured and very agile attack aircraft.

Book excerpt: At its height during the Cold War, Soviet tactical aviation was a large force of fighter, bomber, and attack air regiments with a high degree of readiness - many units stationed outside the Soviet Union saw actual combat. But, even as progressively more refined jet aircraft came into service - Yak-23, MiG-17 fighters and IL-28 tactical bombers, the attack aviation units still flew outdated IL-10 piston-engined aircraft well into the 1950s. Soviet pilots in combat over the People's Republic of China, North Korea, and Cuba, and their role in Eastern Europe combine with more than 500 color photographs, 50 color profiles, details of units, and insignia to give an in-depth look at this important era.

Available in PDF, EPUB and Kindle. Book excerpt: Born in the 1930s, the Soviet Air Force's long-range bomber arm (known initially as the ADD and later as the DA) proved itself during the Second World War and continued to develop in the immediate post-war years, when the former allies turned Cold War opponents. When the strategic bomber Tu-4 was found to be too 'short-legged' to deliver strikes against the main potential adversary - the USA, both Tupolev and Myasishchev OKBs began the task by creating turbine-engined strategic bombers. By the Khrushchev era in the mid/late 1950's the Soviet defence industry and aircraft design bureaux set about adapting the bombers to take air-launched missiles for use against land and sea targets and in 1962 the DA fielded its first supersonic aircraft - the Tu-22 Blinder twinjet, which came in pure bomber and missile strike versions. The Brezhnev years saw a resurgence of strategic aviation with the Tu-22M Backfire 'swing-wing' supersonic medium bomber entering service in the mid-1970s followed in 1984 by the Tu-95MS Bear-H and Tu-160 Blackjack which were capable of carrying six and 12 air-launched cruise missiles respectively. Soviet Strategic Aviation in the Cold War shows how the DA's order of battle changed in the period from 1945 to 1991. Major operations including the air arm's involvement in the Afghan War, the Cold War exercises over international waters in the vicinity of the 'potential adversary' and the shadowing of NATO warships are covered together with details of Air Armies, bomber divisions and bomber regiments, including their aircraft on a type-by-type basis. Over 500 photos, most of which are previously unpublished in the West, are supplemented by 61 colour profiles, colour badges and line drawings of the aircraft and their weapons, making this an essential reference source for the historian and modeller alike.

Available in PDF, EPUB and Kindle. Book excerpt: By the mid-1950s the export of Soviet arms expanded into the Middle East and were immediately sent to war. Forming the backbone of, amongst others, the air forces of Iraq and Syria, Soviet aircraft were involved in major conflicts such as the Suez Crisis, the Six-Day and Yom Kippur Wars, the Iran-Iraq War, the First and Second Gulf Wars and, more recently, the civil war in Syria. Mikoyan MiG-15 and MiG-29 fighters, Sukhoi Su-7 and Su-22 fighter-bombers, Su-24MK tactical bombers, Su-25 attack aircraft, Mil' Mi-8/Mi-17 and Mi-24/25/35 helicopters, Antonov An-12, and Il'yushin Il-76 transports all played their parts in the region's conflicts. Wars which included Egyptian and Iranian forces also took place entirely in the Middle East and full details of both forces using genuine Soviet types (obtained either from Russia or from Iraq) and their Chinese derivatives are examined. Arranged by country and using previously classified sources, "Soviet and Russian Military Aircraft in the Middle East" includes details of combat use and comprehensive fleet lists of all known Soviet/Russian military aircraft. Highly illustrated with over 375 photographs, national insignia and over 150 color profiles the book forms an invaluable reference for modellers, enthusiasts and aviation historians alike.

Available in PDF, EPUB and Kindle. Book excerpt: A fully illustrated technical guide to the Sukhoi Su-25 Frogfoot. The Sukhoi Su-25 Frogfoot was the Soviet Air Force's first mass-produced jet purposely designed for the close air support (CAS) role and was a simple, effective and durable attack aircraft that, by 2012, had seen combat in no fewer than 40 conflicts. Some 630 Su-25s were built between 1979 and 1991, as well as 185 export Su-25Ks, 70 Su-25UB/UBK Frogfoot-B two-seaters that rolled off the production line at the aviation plant in Ulan Ude (UUAP), Russia. The Frogfoot is known as the most cost-effective ground attack aircraft available to the Russian Air Force (RuAF) and, between the RuAF and the Russian Navy's aviation assets, there are some 200–220 Su-25s still in operation. Illustrated throughout with photographs and colour artwork, this title examines the development history, evolution and combat performance of the Su-25 Frogfoot, and details its effectiveness and reliability. Such is the reputation the Su-25 has earned, 19 of the 25 nations to have deployed a Frogfoot variant continue to operate them today.

Available in PDF, EPUB and Kindle. Book excerpt: Closed in 1949, the Sukhoi Design Bureau was reborn in 1953 to meet an urgent demand for a fast interceptor that would counter the threat posed by NATO bombers. It wasted no time developing a succession of missile-armed, Mach 2 interceptors characterized by delta wings; the single-engined Su-9 entered service in 1960, followed by the up-armed Su-11 in 1964 and the twin-engined Su-15 in 1967. Though built in modest numbers, the three types became an important asset for the Soviet Air Defense Force--particularly the more capable Su-15, which unfortunately became notorious for shooting down two intruding South Korean airliners within five years. The Su-15 outlasted the Soviet Union, the last being retired in 1996. There were also several Sukhoi interceptors that remained in prototype or project form. All known versions are described, as are operational details. The book features many rare and previously unpublished photos.

Available in PDF, EPUB and Kindle. Book excerpt: The Su-30MKI family of super-manoeuvrable multi-role combat aircraft share the same numerical designation as the Su-30MKK/MK2 family of combat aircraft although both design groups, despite being directly descendant from the first generation Su-27, took different evolutionary paths. Numerical designation and some first glance looks aside, the Su-30MKI family are fundamentally different designs from the Su-30MKK/MK2 family in terms of primary design role, internal systems and structure; certainly in regards to the latter the Su-30MKK/MK2 having more in common with the Su-27M (first generation Su-35) than the Su-30M from which the Su-30MKI is clearly derived; this design clearly having evolved from the Su-30M which was developed from the Su-27UB two-seat operational conversion trainer variant of the Su-27S single-seat air superiority fighter. This volume covers the evolution of the Su-30 design from the Su-27, which was born out of the T-10 development program of the 1970's. The evolution of the Su-30M interceptor into the multi-role Su-30MK and ergo the Su-30MKI 'super-manoeuvrable' series is detailed. The various design models, the Su-30MKI for India, Su-30MKM for Malaysia, Su-30MKI(A) for Algeria and the domesticated Su-30SM (Russian CM) for Russia and Kazakhstan are described in detail, as are the weapons that can be employed by the respective variants. All technical information regarding the aircraft, systems and weapons have been provided by the respective manufacturers, as have many of the photographs and graphics. Certain elements of text, when pertinent, are taken from the volumes 'Sukhoi Su-35S 'Flanker' E, Russia's 4++ Generation Super-Manoeuvrability Fighter' and 'Sukhoi T-50/PAK FA, Russia's 5th Generation 'Stealth' Fighter'.
