Sukhoi vs MiG

With the re-appearance of the EtAF fighters over the battlefield, it became clear to the Eritreans and their Ukrainian instructors, that they would have to fight down the newly-arrived Ethiopian Su-27s, or the ERAF would not be able to effectively support the war effort. Therefore, on the morning of 25 February four MiG-29s were sent to intercept two Su-27s which were patrolling along the front-lines at Badme. Both Sukhois, flown by Ethiopian pilots, detected the appearance of their opponents in time and attempted to disengage, when - all of a sudden - they came under an attack by several R-27/AA-10 missiles. None of the weapons fired by the Eritreans hit, but after evading them, the Ethiopians decided to turn back and fight. The lead, Maj. Workneh, acquired the enemy and fired what was reported as a "salvo" of R-27s, targeting one MiG-29 after the other. However, all the missiles missed and the only result was that the Eritreans were forced to break their attack - only to be pounced by the faster Su-27s. The result of following dog-fight was one Eritrean MiG-29 shot down, probably by an R-73/AA-11 short range air-to-air missile (fired again by Maj. Workneh). The ERAF fighter came down near Ethiopian Army positions. The fate of the pilot, rumoured to have been the commander of the Eritrean Air Force, Brig. Gen. Habte Zion Hadgu, was not reported by either side. Like his deputy, Col. Abraham Oqbaselassie, Hadgu used to be a EtAF MiG-23-pilot during the Derg regime. He was never again mentioned in the public, but was apparently replaced by Maj.Gen. Teklay Habteselassie, who remains Commander-in-Chief ERAF until today.

Only 24 hours later, a new - but highly interesting - engagement developed over the Badme area. This time, a lonesome Su-27S, reportedly flown by female pilot Capt. Aster Tolossa, was escorting several MiG-21s on a strike mission, when a single aircraft was detected, closing from the direction of Asmara. Capt. Tolossa turned to intercept and identified the target as an - apparently unarmed - Eritrean MiG-29UB. After some manoeuvring, during which there was some kind of communications exchange between the crew of the MiG and the Sukhoi, the Ethiopian was high at enemy's 6 o'clock, when she realized that the pilot of the aircraft in front of her was her former instructor. Capt. Tolossa immediately warned him that she was about to shot him down, and requested the Eritrean to land at Debre Zeit. He disobeyed, and Tolossa pulled the trigger. Exactly which weapon was used remains unknown, but it is highly likely that the Ethiopian used at least two air-to-air missiles, both of which were evaded, and then finished the target with 30mm gunfire. The Eritrean pilot was certainly experienced enough to evade two missiles, and he also knew who and where was the enemy. While it remains unknown if anybody ejected from that MiG-29UB, it is certain that Capt. Tolossa was given a hero's wellcome back at her base; then she was the first female fighter-pilot to show down an enemy fighter-jet in the history of air warfare.

The authenticity of this version remains disputed by different sources. For example, some Ethiopian sources stress that there was no and still is no Capt. Asther Tolossa, flying Su-27s with EtAF at the time, and that the first female EtAF pilot graduated only in June 2004.

Whatever happened, upon obviously losing one more of their precious MiG-29s in effort to deny the air superiority to the EtAF, the Eritreans stopped challenging the Sukhois. On the other side, the Ethiopians would not let them give it another try: the Ethiopian Army already concentrated enough armour and artillery in order to achieve a small breakthrough near Badme. Eritreans managed to stop the enemy short behind their former lines, but their government immediately agreed to accept international peace proposal. Nevertheless, Ethiopians continued with probing attacks, preparing their forces for a final offensive.


There were many skirmishes during the next months and on 18 March 1999 the Eritreans claimed their first large success. On that day two EtAF Mi-35s were to attack Eritrean positions after approaching from the rear. While attacking one of them was hit in the fin area, on the right side, and forced to land behind the Eritrean positions. The other helicopter swiftly landed near the stricken bird, and managed to evacuate the crew, but the helicopter fell into Eritrean hands. Subsequently, the Eritreans proudly presented the captured Mi-35s at the Asmara IAP.

Couple of days later, a further clash between Ethiopian Su-27S' and Eritrean MiG-29s was reported, in which supposedly two MiGs were shot down. Again no better details are known about this air battle, except that quite a number of air-to-air missiles were fired without any hits.

Eritrean Claims

After another period of relative inactivity, almost two months later, on 21 May 1999, Eritrean forces claimed an Ethiopian MiG-23BN as shot down over Badme, however, Ethiopia denied the claim, which couldn't be independently confirmed. The losses of the EtAF were certainly pretty bad by this time: there were rumours of up eight fighter aircraft and three helicopters shot down so far during the engagements with Eritreans. Some reports indicated that most of Ethiopian aircraft claimed shot down by the Eritreans were actually lost to technical problems, or were flown by the poorly trained Tigreans. Indeed, there are indications that at the time the EtAF was engaged with intensive training of its pilots and personnel, flying many training sorties from Bahir Dar and Mekelle, before moving most of its combat aircraft to Gambela. For example, on 20 April 1999, two L-39s were lost during non-related accidents near the Arba Minch airport. Apparently, both were flown by new EtAF pilots, who were underway on their first solo flights. The remnants of at least one of the planes came down in the residential areas, killing 14.

Nevertheless, the operations over the Mereb-Setit front were continued, and on 24 March - as well as on 11 June 1999 - the Eritreans claimed to have shot down more Mi-35s. According to Ethiopian oppositional sources, the situation surrounding one of these two losses was quite chaotic: a Mi-35 flown by two Russian mercenaries and transporting a group of Tigrean militiamen was underway along the Mereb-Setit front, near Badme, when the pilot became disoriented because the Tigreans could not properly read their maps. After some time the pilot decided to land and ask the troops nearby for the way. This was a very dangerous mistake, as he landed behind the Eritrean lines. The Eritreans immediately captured the helicopter, the crew and eight militiamen. It remains unknown what happened to the two Russians subsequently; as mentioned, the Eritrean President promised to behead any captured Russian mercenary.

On 13 and 14 June, the Eritreans also claimed two EtAF MiG-23BNs as shot down, but such reports were never confirmed by independent sources.


Ethiopian "Left-Hook"

On the Eritrean side, Nefedow was underway to Moscow with a pledge for help - and more MiG-29s! However, as Russians were already too deep involved in Ethiopia and Eritrean request was rejected. Thus, Nefedow had to search for new equipment in Georgia and Moldova, where supposed deals for Su-25s combat aircraft and Mi-8 helicopters were made. Contrary to Eritreans, Ethiopians could acquire further planes, like some eight Su-25s, and prepare them for the forthcoming onslaught on Eritrea. Namely, even after experiencing extreme casualties during the fighting around Badme, in early 1999, Ethiopians never stopped announcing their "final" great offensive, which should bring them back territories right to the coast of the Red Sea. Even as a new round of Algerian-brokered peace talks was underway, Ethiopians continued their preparations by purchasing more heavy weapons and concentrating their ground troops, tanks and artillery on the front between Badme and Adigrat. The Eritreans did their best to prepare for defence, and were right in doing so: when on the 4 of May 2000 the peace talks failed because of technicalities of implementing a peace accord, Ethiopian army started its latest attacks.

The Ethiopian offensive came after lengthy preparations. On an unknown site in Tigray, the Ethiopians reconstructed the most important parts of Eritrean positions in the Badme area and studied them carefully. After running several simulations it became clear that a frontal assault would result in a massacre. Therefore, a decision was taken the Ethiopian Army to attack on the western end of Eritrean lines, near Shambukko, and exploit the fact that the enemy was expecting an offensive on the central part of the border. Two brigades of crack Ethiopian troops were trained for months in mountain warfare in order to prepare for this attack.

Upon crossing the Eritrean border unobserved, they reached Shambukko within two hours and then moved south-east, attacking Eritreans from the rear and flank while supported by artillery. Their penetration eventually allowed Ethiopian tank units to breach the main Eritrean position in the area and penetrate deep behind the border. After the initial attack, the EtAF support was crucial: a large number of sorties was flown by helicopter gunships and strike aircraft in order to keep the Eritreans down and preventing their counterattacks against exposed flanks of advancing Ethiopian units. Not only MiG-21s, MiG-23s and Mi-35s were used, but also newly acquired Su-25, one of which was claimed as shot down by an ERAF MiG-29, on 15 May 2000. The pilot. Flt.Lt. Wondu Ghenda was killed. The Russians originally delivered four Su-25UBKs to Ethiopia, all of which had advanced avionics and night-fighting as well as capability to deploy precision-guided ammunition (PGM).

On the same day the EtAF lost also another Mi-35, which was flown by pilot called Eshetu and underway to attack a water tank the EtAF was trying to hit for quite some time without success, when it stumbled over a newly-positioned Eritrean ZSU-23. The helicopter was several times hit in the engine area while attacking the target for second times with 250kg bombs. Usually, the Eritreans did not consider Ethiopian pilots as very bold, but in this case it was reported the pilot Eshetu, frustrated by previous own and failures of his comrades to hit this target, came very low in order to put two 250kg bombs at the tower, which was then indeed destroyed. Eritrean reports about this engagement indicate that they used their old tactics from the 1980s: they would monitor the operations of Ethiopian helicopters and aircraft very carefully, and then move their flaks somewhere along the usual routes. This allowed them to fire at the first aircraft or helicopter which appeared in the morning. This tactics caused several losses to the EtAF already before, and was now to prove once again the importance of pilots constantly changing their ingress-, egress- and patrol-routes.

Highly interesting were also reports which appeared at this time that during the fighting in those days, Ethiopians deployed two Ka-50 helicopter gunships, supposedly recently delivered to them by Russia and also flown by Russian mercenaries. According to some unconfirmed reports, both Ka-50s used only unguided rockets and their guns so far. Indeed, there were some traces - including photographs published in the African press - that the Ethiopian helicopter attacks were highly successful in these days, and that some guided anti-tank missiles were used by EtAF in at least one instance against one Eritrean supply column close behind the front. However, all the reports about the delivery of Ka-50s proved completely wrong: the EtAF flew no other combat helicopters but Mi-35s. Attacks by PGMs stood actually in relation to newly-delivered EtAF Su-25s.

On 16 May 2000 Eritrean Air Force flew couple of counterattacks. Even MiG-29s were deployed in air-to-ground sorties, and seen harassing Ethiopian ground forces several times: one of two incoming MiG-29s were intercepted by EtAF Su-27s. This was a situation which the Eritreans and the Ukrainians wanted to prevent, by challenging Ethiopian Su-27s. Such concerns proved right as at least one MiG-29 was damaged sufficiently to crash-landed at Asmara, obviously after being damaged by R-27. The ERAF remained stubborn. Only two days later, two MiG-29s were scrambled to intercept an incoming formation of EtAF MiG-21s. The leading Eritrean pilot missed with his R-27s, but then shot down at least one of Ethiopian fighters, using the 30mm gun during a short dogfight. Nevertheless, only minutes later, the same MiG-29 was in turn intercepted by a pair of EtAF Su-27s. As the Sukhois engaged, one of them collided with an Africa Buzzard (a very large bird), and had to return to base after sustaining heavy damage. The other Sukhoi -flown by one of former Derg pilots - continued, engaging the MiG and shooting it down by a single R-73.


In response to renewed activity of the ERAF, on 19 May Ethiopian MiG-23BNs bombed the Sawa military training centre and airfield. This operation stunned observers, because the installations at Sawa were considered as very good defended and fortified. However, all Ethiopian aircraft returned safely to their bases. In fact, instead of being shot down by Eritrean SA-6 SAMs, Ethiopian aircraft reportedly destroyed one site of those missiles, close to Mendefera, on 20 May 2000. Nevertheless, Eritrea - whose forces were now under heavy pressure along the whole central part of the front - claimed downing of no less than four Ethiopian MiG-23s on 24 of May. Two additional EtAF jets were also claimed as shot down during a bombing of Adi Keyib. Some reports indicate that the Ethiopians indeed lost many pilots and aircraft in these days, but mainly because of pilot mistakes and technical failures. In fact, a private contractor who used to work with EtAF at the time indicated the Ethiopians were losing pilots due to poor navigational skills, and run their MiGs out of fuel.

The Eritreans were in no better position on the ground. Ethiopian Army attacked along a very broad front, without revealing its actual target: cutting off of all Eritrean forces at Zalambessa. Thus heavy fighting was reported near Senafe, down to Mereb river valley, south of Tserona and toward Adi Quala, where Eritreans managed to recover a tactically important hill in hand-to-hand fighting. Both sides intensively used armour, artillery and rocket launchers during those battles causing a considerable surprise for the observers in the West. However, the EtAF stopped any operations over the front and operated with its fighters only over Asmara.

On 28 May 2000, Ethiopians escalated the war further by an attack of two MiG-23BNs against the newly built power-plant close to Hirgigo, near Massawa, sponsored by Mid-East donors and Italy. On the same day, during decisive battles in the mountains, Ethiopians broke Eritrean lines and captured Zalambessa. The city was completely destroyed during the fighting. Retreating in the face of the advancing Ethiopian columns, the Eritreans also abandoned Adi Keyih, south of Deke and just 96km from Asmara. The Ethiopians, however, concerned of fuelling Eritrean claims that Addis Ababa wants to re-annex whole country, stopped their advance short of this city, instead turning south and marching on Areza: their left hook brought the Eritrean front to collapse and the Ethiopians hoped the message was delivered.


Drive towards Aseb

The next escalation was achieved by Ethiopian strike against Asmara on 29 May 2000. At midday, four MiG-23BNs appeared over the Asmara international airport and attacked with rockets. The small control tower was hit and burned out. In their second turn, MiGs split their formation in two pairs: the first two attacked the military side of the airfield and tried to hit parked Eritrean aircraft and helicopters with bombs. However, they missed and at least one Eritrean MiG-29UB as well as one Mi-35 were not damaged even by bombs that fell relatively close. Two other MiG-23BNs bombed military buildings and set couple of them on fire. At least one Eritrean MiG-29A started immediately after the attack and gave Ethiopians a chase, but couldn't reach them any more. During the evening fighters of the ERAF continued their patrols over Asmara but, after this attack, the remaining commercial airlines flying to the capital of Eritrea have suspended their service as a precaution.


Fierce battles raged along the front in the following days, with Eritrean hit and run counterattacks near Barentu and Zalambess, staged in order to bolster the morale of their battered military, and bombing of the port of Assab by two Ethiopian MiG-23s, on 2 June 2000. However, in a flagrant violation of their own claims about a pull-back from all territories captured so far, on the morning of the 3 June 2000, Ethiopian troops started a new offensive at the front close to Burre, broke through and started operations against the second Eritrean defence line - only some 37 kilometres form Assab. This offensive was initiated under considerable constraints: the Ethiopian General Command wanted to employ the same tactics of deep outflanking of enemy positions, like previously in the Badme area. This, however, would result in capture of Assab, which was politically unacceptable. Consequently, a much more shallow attack profile was chosen instead, which resulted in no new deep penetration.

At the same time mediators from the OAU, the EU and Libya went to the region and tried to arrange a ceasefire. Their efforts became successful only two weeks later, after a new small Eritrean offensive, in which the city of Tessena could be liberated. On Saturday, 18 June 2000, under heavy pressure from outside, Ethiopia and Eritrea agreed immediate ceasefire. However, a comprehensive peace is still very far from being achieved, as this agreement falls far short of a full settlement and depends heavily of the arrival of some 5.000 UN Peacekeepers, which should arrive in the are during the nest two or three months. While new clashes on the ground and in the air could easily break out before the Peacekeepers arrive, the UN should have a considerably easier task in separating Ethiopian and Eritrean ground forces from each other, because both sides deployed good organized and trained armies during the fighting, which so far claimed lives of some 100,000 soldiers and displaced almost a third of Eritrean population.


Conclusions

Couple of events that happened in this two years long bloodshed are very interesting for all observers. Firstly, while there are still many observers in the West, which refuse to believe that two of the poorest African countries could "put up such a war" - and use such high-tech equipment like Su-27s, MiG-29s, Mi-35s, tanks, artillery and rocket launchers in large numbers and in tactically and strategically feasible manners - the fact remains that under a closer look the operations of both sides made very much sense. Consequently, both the Ethiopians and the Eritreans have carefully planned and ????uted their moves, even if not everything functioned.

As second, even if both sides suffered grievous losses during the fighting (according to some reports, possibly as many as 150,000 people already lost their lives during the fighting), some tactical decisions (supposedly "produced" by foreign "instructors"), like the Ethiopian left-hook at Barentu, with the closely-following push towards Aseb - were very interesting.

Very interesting were also clashes between Ethiopian Su-27S' and Eritrean MiG-29s. Besides taking out four Eritrean MiG-29s - plus writing another off due to damage received from an air-to-air missile - Ethiopian Su-27s flew many strike missions against the Eritrean ground forces, using unguided rockets and "dumb" bombs, and also escorted almost all MiG-23 deep strikes into Eritrea. Interesting is also, that most - if not all - Eritrean MiG-29s were shot down in close-quarters turning dogfights, where MiGs were supposed to have some advantages over larger and heavier Sukhois. Finally - except one - all the air-to-air kills were reportedly scored by R-73, even if quite a few (up to 24) R-27s were fired, pointing to some possible problems with R-27s, which is otherwise highly praised by quite a few air forces around the world! Supposedly, there should be no significant differences between early and new - or domestic and export - versions of R-27s, however, it seems, that this type so far has a worst combat record than even US Vietnam-era AIM-7Es or AIM-7Fs! This was certainly no good news for the Russians, which were keen to try out their new mounts and weapons under conditions of conventional warfare, and against a well organized enemy.

Finally, already in 2000, there was a question about the capability of both air forces to keep their aircraft up and flyable once their Russian and Ukrainian instructors would leave, while also the actual reasons behind the massive Russian support for Ethiopia were completely unclear.

By now, it is clear that the Russian interests were foremost of commercial nature. The subsequent commercial successes of the Su-27s and other Russian-built equipment on international markets, as well as the pull-back of almost all instructors after approximately 12 months in Ethiopia, seem to confirm this. Once most of the Russians have left, however, the situation of the EtAF detoriated again. Newest reports indicate that hardly four Su-27s are operational on average. The efforts to improve the situation with the help of the newly established "Ethiopian Aircraft industries" (DAMEC) works, built by the Russians at Debre Zeit in 1999, and now supposedly supported even by the Israelis, should not have brought any useful results so far. Nevertheless, at least theoretically, the Ethiopians are left in a slightly better situation than Angolans or the government of Sierra Leone, where the regular forces almost broke down after their foreign instructors have left. After all, a number of former officers and technicians of the Derg-times EtAF, who used to work as mercenaries in Angola, Sierra-Leone, Uganda and some other African countries as technicians and pilots in the 1990s, were allowed to return back to Ethiopian Air Force during the war with Eritrea.

Indeed, while the Eritreans are still not especially interested in revealing more about their experiences from this war, the Ethiopians are very proud about the achievements of their deadly Su-27s. Nevertheless, the Eritreans have continued their relations to the Ukraine, but also established better connection to Moscow. While only a small cadre of the Ukrainians remained there after the war, in summer 2001 the EtAF purchased four new MiG-29s from Russia, in order to replace the losses from the war with Ethiopia and bring their fighter squadron back to strength.
