Twelve aircraft, more than one burden
Ethiopia’s new Su-35 fleet begins with the number 12. Prime Minister Abiy Ahmed announced that delivery was a year early. The air force already has Su-27s and two Su-30Ks acquired in 2024. The shared design family means personnel are not entering an entirely unfamiliar world. Common ancestry does not erase the training and maintenance burden of separate types. The military weight of this purchase lies in the transition from aircraft delivered to aircraft kept available.[1]
The War Zone identifies concrete requirements: specialised pilot training, maintenance infrastructure, weapons integration and dependable spare parts. These are the services that make an aircraft usable. My assessment is that earlier delivery does not by itself complete that transition. An alternative is that preparations advanced before the aircraft arrived. The agreement’s price and readiness data have not been disclosed, so declaring the transition a failure would also be premature.[1]
The supplier has its own fleet
Russia also has its own Su-35 fleet to support. The war in Ukraine and sanctions restricting component access are two sources of supply pressure identified by The War Zone. That does not establish that parts shipments to Ethiopia have stopped. The militarily important issue is dependence: keeping the new fleet available continues to require Russian industrial support after the handover. Completing the sale and sustaining the support relationship are separate obligations.[1]
Existing Su-27 experience may ease the burden. That is the strongest counterargument: Ethiopia is not building a fighter organisation from nothing. Familiarity with the family nevertheless does not establish that every maintenance tool, trained person and part required by the new type is available. Reading the purchase solely as growing foreign dependence is therefore incomplete too. A modernisation gain and an operating burden coexist; aircraft numbers alone do not determine net readiness.[1]
The S-400 is a separate stage
The four S-400 batteries in the agreement have no announced delivery schedule. Adding them to the Su-35 announcement as a complete air-defence structure today confuses a plan with a delivery. Fighters and ground-based air defence require different service-entry processes. There is no announcement that Ethiopia has made both capabilities operational together. A military assessment needs to keep the aircraft reported delivered separate from the batteries without a stated date.[1]
Abiy presented the purchase as protecting sovereignty and deterring aggression. More capable aircraft can contribute to protecting airspace; force protection is a plausible alternative to interpreting the purchase as preparation for attack. The stated purpose does not establish a change in an adversary’s behaviour. The concrete advance is the announcement that a more developed fighter type has joined the fleet. My judgement is bounded: modernisation has value, but sustainable force availability determines the weight of a deterrent. Early delivery begins that calculation.[1]
