The Rocky History of Ariana Afghan Airlines

Ariana's logo- note the use of the Pan Am font

Prior to the Second World War, air services to Afghanistan were adventurous to say the least, given the inhospitable terrain of the area. Most air links to South Asia of the day that connected the region to Europe passed via India and were controlled by primarily the British. The first air links to Afghanistan, however, came by way of the Soviet Union starting on 14 September 1926 when the Russian airline Dobrolyot connected Kabul to the other Central Asian cities under Soviet control with Junkers F13 monoplanes. Dobrolyot was founded in 1923 to develop air services in the Soviet Union and in 1932 it was Dobrolyot that formed the nucleus of a new airline, Aeroflot. Dobrolyot's air services to Kabul continued until the outbreak of the Second World War. Interestingly enough, Dobrolyot was not the only foreign airline active in Afghanistan in the interwar period- DLH (Deutsche Luft Hansa, predecessor to today's Lufthansa) also opened air services to Afghanistan. At the time, DLH was looking to extend its route network to China where there were substantial German business interests. However, remaining bitterness from the First World War stymied DLH's attempts to open routes to China via India, so going through Afghanistan was seen as a short cut around British influence in the area. DLH extended its network eastward from Istanbul to Baghdad in October 1937 and then extended again from Iraq to the Iranian capital of Teheran in April 1938. Two weeks later, DLH extended its network again, this time connecting the Afghan cities of Kabul and Herat via Teheran and at the time, it was the furthest corner of DLH's airline network. Services ended abruptly, though, in August 1939 on the eve of the outbreak of the Second World War. 

Air services to Afghanistan were spotty at best and ad hoc for the duration of the Second World War  and aside from a small air mail service using Hawker Hart biplanes, it would be an American businessman in India who would forge new air links into Afghanistan again at the end of the war. New York native Peter Baldwin had served with the US Army Air Force in India during the war and returned in 1945 leading a US government mission to oversee the disposal of surplus USAAF aircraft in the region. His job finished, he elected to stay in India and in 1947 formed a company in Bombay (Mumbai today) for the sales of light aircraft and airport equipment. By 1950, he had his own fleet of thirteen Douglas DC-3s that he was flying all over the region on charter flights all over India, the Middle East and as far as Africa. His small charter operation even operated Hajj flights to Mecca. It was in this capacity that he came into partnership with the Afghan government. 

The DC-3 services were a boon to a country without railroads.

In 1951, the Kabul government established a branch of the Royal Afghan Air Force that was tasked with civil aviation development with Colonel Gulbar Khan as the head of what was called the "Hawabazi Mulki". Colonel Khan worked out a partnership with Peter Baldwin to form a new Afghan airline which was established on 27 January 1955 as Aryana Afghan Airlines in Kabul with Peter Baldwin holding 49% ownership of the airline and the Kabul government owning 51%. I haven't been able to determine if the airline's first three DC-3 aircraft were from Baldwin's charter operation, but it would make sense given his signifcant ownership in the new venture. The first services were launched at the end of 1955 connecting Kabul to Mazar-i-Sharif in the north near the Soviet border via the city of Kunduz. What had taken a week on the region's poor roads now only took three hours. 

During the Pan Am years, the Ariana chief pilot was a Pan Am pilot

On 27 June 1956, the Kabul government signed an air transport and development agreement with the United States. At the time, both the Soviet Union and the United States were eager to get Kabul's business and the Afghans astutely played both sides off each other to get economic development agreements. The air agreement with the United States included Pan American buying out Peter Baldwin's interest in Aryana. As a result, Pan Am become responsible for all operational and technical matters and also changed the spelling of the airline's name to Ariana, ostensibly to eliminate any possible references to the word "Aryan" that had been corrupted by the Nazi regime during the Second World War. On 3 June 1956, an Ariana Douglas DC-4 with an all-Afghan crew trained by Pan Am departed New York for Kabul to begin Hajj flights to Mecca. The DC-3s were used for internal domestic services that connected Kabul to Herat, Kandahar, Kunduz, Mazar-i-Sharif, and Maimana. New Delhi was connected to Kabul via the Indian city of Armistar and Karachi, the Pakistani port city, was connected via Kandahar. The DC-4 was used to connect Kabul to Teheran, Beirut and Damascus via Kandahar where American economic development funds were used to build a modern airport and terminal facility. 

Ariana launched services to Europe on 11 September 1959 on what they called the "Marco Polo Route" which used the DC-4 on services to the Turkish capital of Ankara via Beirut. The flight then continued on to Prague and then terminated in Frankfurt. The airline had to replace its DC-4 with a larger DC-6B as adventurous European tourists began to fly the "Marco Polo Route" to Kabul. The airline soon found that it was more profitable for the DC-6B services to bypass Kabul and instead fly Kandahar to New Delhi. Political instability in the region in the 1960s resulted in the termination of services to Karachi and the services that connected Frankfurt to New Delhi could only be flown twice a month- soon after, European services were cut altogether with Ariana's westernmost destination being Beirut by 1962.

Ariana Afghan 727-200

Ariana was near dormant when American development funds arrived again in 1963. This was a time of superpower rivalry and Afghanistan was no different than any other non-aligned nation of the time that had both American and Soviet interests competing for influence. Ariana got an extremely low-interest loan (it was pretty much a gift) that included a second Douglas DC-6 and two ex-Pan American Convair CV-340s to replace the DC-3 on the domestic services. A third CV-340 was purchased from Allegheny Airlines and this allowed a return to Karachi via Kandahar as diplomatic relations between Pakistan and Afghanistan improved. In July 1965, Ariana opened DC-6 services to the Uzbek capital of Tashkent in a pooling agreement with Aeroflot and in the following month, services to Europe resumed with DC-6 services from both Kabul and Kandahar to London Gatwick, stopping only in Beirut and Frankfurt. In April 1968, Ariana got its first jet equipment with a Boeing 727-100 which replaced the DC-6s on the European services. The route to London was reconfigured to route via Teheran, Istanbul and Frankfurt, but as Ariana had no fifth freedom rights, only Kabul/Kandahar-bound passengers could be boarded at London Gatwick. That first 727 crashed in dense fog on approach to London on 5 January 1969, but two more 727s were added- the first a lease from World Airways that was bought outright and a second purchase from Executive Jet Aviation, arriving in 1971.

The domestic routes of Ariana were spun off under a subsidiary airline called Bakhtar Afghan Airlines. This was a political move more than anything else as some Afghan officials wanted to limit US influence in the northern tier of cities along the Soviet frontier- this was accomplished by cutting Pan Am out of Bakhtar's operations. In 1973, Bakhtar took delivery of three Yakovlev Yak-40 trijets, becoming one of the few non-Soviet client state customers for the 28-seat feeder jet. Pan Am was still needed in the Ariana international operation, though, as Pan Am sold Ariana a Boeing 720B on very generous terms (again, it was pretty much a gift) in May 1973. That year, though, on the heels of a severe drought 1971-1972, Prime Minister Mohammed Daoud Khan seized power in a non-violent coup, deposing King Zahir Shah and ending the Afghan monarchy. A republic was proclaimed to institute economic reforms but only political instability was established as various Afghan leaders relying on tribal loyalties began to vie for control of the country. A series of coups followed starting in 1978, but despite this, Ariana launched Douglas DC-10 Series 30 services with a single aircraft in October 1979 on its services to London which could now be served nonstop. On 24 December 1979, the Soviet Union invaded Afghanistan which for all intents and purposes ended Ariana's operations. The two 727s and DC-10 were parked and eventually sold off under Soviet pressure by 1985. Its regional subsidiary, Bakhtar, took over Ariana's operations with two Tupolev Tu-154M aircraft starting in 1987, but the following year the Ariana name was resurrected and Bakhtar's domestic routes and operations folded into Ariana. 

Ariana's sole Douglas DC-10

The country descended into outright civil war following the Soviet withdrawal in 1989. Communist President Najibullah's regime only lasted to 1992 and with the Taliban takeover in 1996, worldwide sanctions crippled what was left of Ariana's operation. Pakistan set up a temporary maintenance base for the airline in Karachi, and only Dubai remained as the airline's only international destination. During the Taliaban's regime, Al-Qaeda operatives were given Ariana identification to allow them to move arms, personnel and opium shipments between Dubai and Pakistan. There were indications that Russian arms dealers were operating Ariana during this period. By November 2001, only a month before US-led forces toppled the Taliban regime, Ariana was finally grounded for good. Ariana would be resurrected in the post-Taliban era, but that's a subject for another blog posting in the future!

How Aleksandr Yakovlev's Rivalry with Pavel Sukhoi Did Him In

Aleksandr Yakovlev

The 1950s and 1960s in Russian combat aircraft development were marked by intense rivalries between the various design bureau (OKBs) heads. Nowhere else was this seen than with the rivalries between the respective OKBs of Artem Mikoyan, Pavel Sukhoi, and Aleksandr Yakovlev. During the Second World War, Yakovlev's OKB was one of the dominant forces in Russian aviation, having built thousands of fighters for the Soviet air forces. OKB MiG (Mikoyan and his partner, Mikhail Gurevich) was rapidly rising to prominence during the war. OKB Sukhoi really didn't start to establish itself until well after the war (some say that Stalin had a dislike of Pavel Sukhoi as one reason). As the jet age dawned, Yakovlev took a conservative approach that saw the first Yak jet fighters as jet derivatives of his wartime piston engined designs whereas MiG and Sukhoi were willing to push the envelope and advance the state of the art. A rivalry between Sukhoi and Mikoyan developed with Mikoyan gaining the upper hand against both Yakovlev and Sukhoi with the MiG-15, MiG-17, and MiG-19 fighter designs which outclassed comparable aircraft from Yakovlev. When in the 1950s the Soviet military command wanted a supersonic interceptor, it was Sukhoi's delta winged Su-9 (NATO code name Fishpot) that edged out Mikoyan's design based on an enlarged MiG-21 fighter. First flying in October 1957, the Fishpot was certainly fast, but it was handicapped by the poor reliability of its Lyulka AL-7F turbojet. In those days, it was rare for an AL-7F engine to last beyond 200 flight hours- and that's not time between overhauls, the reliability of the engine was so poor that few engine units lasted past 200 flight hours, an abysmal figure. The radar set in the conical shock cone of the nose inlet was limited as well. 

Sukhoi Su-9 "Fishpot"

Of course, having the Su-9 having much in common with the Su-7 (NATO code name Fitter) tactical fighter did make selecting the Su-9 for production much easier. But the Sukhoi OKB knew that the Soviet Air Defense Forces (PVO) was not pleased with the performance of the Su-9 and with only 924 examples built, an upgraded Su-11 was introduced. But it would be built in very limited numbers. At the time, the Soviet leadership had decreed that the "missile age" had made many aircraft designs obsolete, and like the infamous Duncan Sandys Defence White Paper in the UK that mortally wounded the British aerospace industry, numerous aircraft and engine projects were canceled and only those designs that were developments of existing designs were allowed to continue to develop. As the Yakovlev OKB had already in production the Yak-25/26 interceptor (NATO code name Flashlight) and attack variants, it proceeded with a supersonic design in the Yak-28 (the interceptor variant having the NATO code name Firebar and attack version being the Brewer). Three features made the Yak-28 more attactive than the Su-9/Su-11 family- first, it used the Tumansky R-11 turbojet was showing itself in the MiG-21 to be much more reliable and durable than the Lyulka AL-7F, secondly it had two engines which gave in a perception of safety over the single-engined Su-9/Su-11 family, and thirdly, having a nose free for a larger radar set than what was possible with the nose intake arrangement of the Sukhoi design meant that production was switched over to the Yak-28 instead, the interceptor version being the Yak-28P. 

Yakovlev Yak-28P "Firebar"

Sukhoi wasn't going to be one-upped by Yakovlev, though. Taking as a baseline the limitations of the Su-9/Su-11 family. OKB Sukhoi set about to create a vastly improved interceptor in the shape of of the Su-15 (NATO code name Flagon). The Su-15 was designed from the outset to be superior to the Yak-28P- it used two of the same Tumansky R-11 engines and used lateral box intakes to leave the nose section free for the same large radar set used on the Yak-28P, the Oryol-D radar. Being a development of the Su-9/Su-11 family, though, it managed to avoid cancellation like so many other projects in the 1958-1959 timeframe in the Soviet Union. Interestingly, the Yak-28P and the Su-15 were produced in the same factory- in the Soviet Union, the OKBs only did design and flight test work with workshops for building prototypes. The designs were then handed off to independent factories for production.  At the time, the Novosibirsk aircraft factory No. 153 was responsible for the Yak-28P production and it was assigned production of the Su-15 once it had passed its State acceptance trials in 1962. Given that both the Yak-28P and the Su-15 used the same powerplant and radar, producing both at the same plant made logistical sense. And there was irony in the decision as the same plant built the Su-9/Su-11 interceptors that were replaced in production at that very plant by the Yak-28P. And now the plant was gearing up to produce more Su-15s with the intent of replacing the Yak-28P with the PVO. 

The sole Yakovlev Yak-28-64 prototype

Not willing to lose out to Pavel Sukhoi, Aleksandr Yakovlev dispatched one of his sons to the Novosibirsk plant to learn as much as he could about the Su-15 design (Yakovlev had two sons who worked for him- one would end up designing the Yak-40/42 airliners and the other would be responsible for the Yak-52 trainer). Seeing the threat posed by the Sukhoi design to the Yak-28P, Yakovlev set about designing an upgraded version provisionally designated the Yak-28-64 (due to work on it beginning in 1964). Many of the features of the Su-15 were incorporated into the Yak-28-64, primarily in moving the Tumansky R-11 engines to the rear of the fuselage from the wings. One of the criticisms of the Yak-28P was that having wing-mounted engines gave the aircraft a poor rate of roll and adverse handing characteristics in an single engine-out situation. Moving the engines to the fuselage resolved these concerns. The tail unit and the wings remained close to that of the Yak-28 and the unique bicycle landing gear was retained. The single ventral fin of the Yak-28P was changed over to a twin ventral fin arrangement for stability. Given that OKB Yakovlev had little experience with fuselage-mounted lateral intakes, Yakovlev incorporated a copy of the Su-15's lateral box intake design on the Yak-28-64. 

Yak-28-64

The prototype Yak-28-64 was rolled out in 1966 and it proved in flight tests right off hand to be a dog. In fact, the Yak-28-64's performance was even worse than that of the Yak-28P, the very aircraft that was being superseded by the Su-15. Numerous unpleasant handling characteristics were also uncovered and some of the landing issues present in the Yak-28P thought to be cured in the Yak-28-64 persisted (such as aileron reversal at high speeds). It didn't take long to realize that the Yak-28-64 was a dead end and the project was abandoned by Yakovlev. 

Sukhoi Su-15 Flagon

A look at some of the production figures during this rivalry is telling. Just over 900 Sukhoi Su-9s were built at the Novosibirsk factory. Less than 100 Su-11s were built. Replaced in production at the factory by the Yakovlev Yak-28P, over 400 examples were built before it was completely supplanted by production of the Su-15, of which over 1,200 were built. The attack versions of the Yak-28 had to be continually upgraded with no less than 10 versions, each in relatively small production batches around 200 or so. Having been topped by Sukhoi in the interceptor arena with the Su-15, the Soviet air forces replaced the attack versions of the Yak-28 with another Sukhoi design, the Su-17/Su-22 family (NATO code name Fitter) which proved more reliable and versatile operationally. 

The Yak-28-64 and the rivalry with Pavel Sukhoi damaged OKB Yakovlev for good. His designs were considered by the Soviet air forces to be unreliable and obsolete, at the worst, limited in performance at best. For years no other Yakovlev combat aircraft design was taken seriously by the Soviet military high command and even the VTOL Yak-36 design was supremely limited in its utility. Even Yakovlev's submissions to the  competition that resulted in the MiG-29 Fulcrum and the Sukhoi Su-27 Flanker (Yak-45 and Yak-47, respectively) were decidedly archaic in appearance and failed to use some of the latest advances in aerodynamics. Most Yakovlev designs following the abandonment of the Yak-28-64 were either light aircraft or airliners, areas that were more heavily influenced by his sons than by Aleksandr Yakovlev himself.

Soviet Wild Weasels: Part Two (Aircraft)

Yakovlev Yak-28PP "Brewer-E"

Last night we took a look at the nuts and bolts of Soviet suppression of enemy air defenses (SEAD) doctrine and tactics. Tonight we'll continue along that them with a look at the aircraft that filled the role of  "Wild Weasels" in the Soviet air forces. Like the United States, the Russians had put into service several specialized aircraft that were used to knock out and/or jam enemy radars and surface-to-air missile sites. These aircraft were based upon established production types much in the same way the USAF Wild Weasels were adaptations of production fighter aircraft. The first aircraft to fill this role was the Yakovlev Yak-28N, an experimental adaptation of the Yak-28 "Brewer" attack aircraft. This version of the Brewer was the first Russian development for a Wild Weasel-class aircraft; work began by OKB Yakovlev in 1964-1965 with a production Yak-28I being set aside in 1965 for conversion to the -28N configuration. The attack Yak-28I had the "I" suffix as it was equipped with the Initsiativa-2 ground-mapping/bombing radar in a ventral radome aft of the nose gear. On the Yak-28N, the Initsiativa-2 radar was replaced by radar pulse detection unit that would seek out and locate enemy radar emissions and provide targeting data to Raduga Kh-28 (NATO code name AS-9 "Kyle") missiles, one each under the outer wings. The Kh-28, which I'll discuss in a subsequent post, was the first Russian anti-radiation missile to be fielded with the first operational examples coming out in 1964. 

By the time operational testing of the Yak-28N was completed around 1972, it had been far outclassed by contemporary Russian and American designs and the project was canceled. However, the work that had been put into the Yak-28N wasn't wasted as the Soviet air forces still needed a battlefield electronic warfare aircraft that better performance and was more flexible than the existing design in use, the Tupolev Tu-16PP Badger which clearly by 1972 was too big and too slow to survive in hostile airspace. The Yak-28 was again used as the basis for the Yak-28PP electronic warfare aircraft that crammed the jamming equipment of the Tu-16PP into a much smaller airframe. All of the armament provisions of the Yak-28 were deleted and four different jamming systems were installed in the Yak-28PP, which was marked by a number of dielectric bulges and blisters on the fuselage. The jamming systems generated so much heat that two heat exchangers were installed in the lower aft fuselage ahead of the aft bicycle gear to help cool the avionics. The outer wing pylons were fitted with rocket pods that fired chaff ahead of the aircraft to help sow chaff corridors to protect inbound strike packages. Below each engine nacelle of the Yak-28PP was a system for deploying bundles of fiberglass-based chaff strips in mass quantities. The role of the Yak-28PP was to accompany inbound strike packages with three of the ECM -28PPs sowing a chaff corridor on each side of the strike aircraft formation as well as using its powerful jamming equipment to blind NATO air defense radars. The first Yak-28PPs completed their State acceptance testing just as the Yak-28N was canceled. Most of the Yak-28PPs that were built (NATO code name "Brewer-E") were based with the Soviet forces in East Germany. 

MiG-25BM armed with Kh-58 missiles

The cancellation of the Yak-28N in 1972 came about due to the arrival of an aircraft with significantly higher performance that would become the first Russian production Wild Weasel-class aircraft, the Mikoyan MiG-25BM "Foxbat-F" based on the production interceptor version. It was recognized early on in the Foxbat's flight test program that a high-flying, high-speed aircraft would make an ideal SEAD aircraft- as it was proved itself immune to interception during operations over the Sinai prior to the Yom Kippur War, a SEAD Foxbat could out-fly defending fighters, fire its anti-radiation missiles, and streak back with impunity. While early anti-radiation missiles like the Kh-28 mentioned already were heavy, the newer generation of anti-radar missiles like the Raduga Kh-58 (NATO code name AS-11 "Kilter") were much lighter and imposed little performance penalty on the Foxbat. 

Mikoyan MiG-25BM Foxbat-F in East Germany

At first the MiG-25BM was to be a dual-role reconnaissance/SEAD aircraft, the concept being that it would use its SEAD capability to allow it to penetrate deep into NATO airspace to complete its reconnaissance mission. By 1977 both the Soviet air forces and Mikoyan realized that the aircraft would be compromised in both roles and different Foxbat variants were developed for each role, with the MiG-25BM being the definitive SEAD variant. The MiG-25BM featured an integrated avionics package called Yaguar (Jaguar) that not only detected and located enemy radars, but it also networked with the Yaguar systems of other MiG-25BMs to allow a "wolf pack" of SEAD Foxbats to operate deep into NATO territory and share data and targeting information with other members of the wolf pack. The Yaguar system included target designation functions that cued the seeker heads of the four Kh-58 missiles that the MiG-25BM carried. In addition to the missiles, nuclear warheads could also be delivered to either knock out SAM missile sites or generate an EMP to short out communications and electronic systems. Several internal active ECM jammers were also carried which not only protected the MiG-25BM from air defense radars but could also counter fighter radars as well. The Foxbat-F was in production from 1982 to 1985, but the complex systems of the aircraft meant that only 40 examples were built. Nearly most were assigned to units stationed in East Germany and were unusual in being the only Foxbats to wear camouflage as the reconnaissance and interceptor variants were gray in color. Despite production ending in 1985, continued technical problems that had to be resolved meant that the first MiG-25BMs weren't operational in East Germany until 1988 with the Group of Soviet Forces Germany (GSFG), which ultimately withdrew from German soil in 1994.

The last SEAD aircraft developed for the Soviet air forces was the Sukhoi Su-24M "Fencer-D", but by this time the Fencer-D was less an dedicated SEAD asset and more an attack aircraft that had SEAD capabilities. Unlike the Yak-28N and the MiG-25BM that housed a large amount of equipment internally, technological advances meant that the Fencer-D could carry most of the radar detection and location equipment in a pod mounted on the centerline underfuselage which was called Fantasmagoria, with -A, -B, and possible -C version depending on the internal configuration of the pod. This was similar to the USAF where the Lockheed Martin F-16CJ replaced the specialized F-4G Phantom Wild Weasel. The F-16CJ had a small pod called the HARM Targeting System (HTS) that performed the same role as the Russian Fantasmagoria pod. The Su-24M could carry two kinds of anti-radiation missile, either the Kh-58 as was used by the MiG-25BM or the newer Kh-31 (NATO code name AS-17 "Krypton") missile. 

Sukhoi Su-24M Fencer-D, note the Fantasmagoria pod

The closest that Russian SEAD aircraft came to being committed to action came during the Soviet invasion and occupation of Afghanistan fron 1979 to 1988. During the war, Tupolev Tu-16 Badgers were used to bomb Mujaheddin positions, but were often tracked by Pakistani air defense and early warning radars. It was proposed to use the Su-24Ms to knock out the Pakistani radars which were providing warning information to Mujaheddin forces, but it was realized that it represented a significant escalation of the conflict and only limited cross-border raids were conducted with SEAD protection. During the Russian-Georgian War of 2008, it is believed that Su-24Ms were used against Georgian air defense positions, but poor tactical coordination resulted in the Georgians shooting down two Fencers. 

The last installment of this series will take a closer look at the anti-radar missiles that the Russians fielded for their SEAD assets. Stay tuned!

While most nations that had used assault gliders operationally in the Second World War had already abandoned the concept with the end of the war, development continued in the Soviet Union on gliders not only for combat assault, but also for use internally for the delivery of cargo to inaccessible areas of the country. In 1947, the Soviet Air Force issued a specification for an assault glider for use by the Aviation of the Airborne Troops that could transport over 3.5 tons of cargo. Both OKB Yakovlev and OKB Ilyushin were selected to build prototypes- Ilyushin instructed to develop an all-metal design (the Il-32 and was generally unsatisfactory) and Yakovlev's design was to be all-wood and became the second use of the designation Yak-14 (the first Yak-14 was the original designation of the Yak-10 light liason aircraft and was one of the reasons the NATO code name system was created to avoid confusion).

The Yak-14 had a wooden structure with fabric skinning with a hinged nose section as well as a hinged tail section, both of which could be swung to one side to allow straight-through loading and unloading to a square-section cabin with a floor strong enough to carry tracked vehicles. The cockpit was curiously offset to one side and was above the cabin and the high-mounted wing. Up to 35 fully-equipped troops could be carried.

Flight testing of the Yak-14 began in 1948 with the planned tow aircraft either a Tupolev Tu-2 light bomber or a Ilyushin Il-14 transport. In March 1954 four Yak-14s were used to deliver heavy equipment to a research station on an ice floe in the Arctic Ocean, becoming the first glider to overfly the North Pole in the process.

With the arrival of twin- and four-turboprop transports from Antonov in the late 1950s, the Yak-14s were phased out as the last assault gliders in operational use. Approximately 413 were constructed and assigned the NATO code name "Mare".
