Algeria refuses to buy Su-35 due to lack of AESA on-board radar
ALGIERS, ($1=139.10 Algerian Dinars) – Algeria has refused to buy a Russian Su-35 fighter jet, despite reports in Russian media that negotiations to order these aircraft from North Africa are still in force, learned BulgarianMilitary.com, according to Express Defense.

Among the official reasons for this refusal is that Algeria plans to strengthen its air force in other ways. These include the retrofitting of Su-30MKA fighters with AL-41 and Irbis-E radar engines, as well as the possible purchase of a Russian Su-57.
However, Algerian military analysts say the main reason for abandoning the Russian Su-35 is the efficiency of the on-board radar station, which also costs about 60% more than the Su-30MKA.
It is noted that Algeria’s requirements for air superiority include the integration of active electronically scanned array radar [AESA], which Russia has not yet integrated into any fighter operating in the squadron.
Indonesia did the same
As we reported last december, the US Congress announced in a recent report the final termination of the Indonesian contract for the supply of 11 Russian Sukhoi Su-35 fighters [NATO code “Flanker-E”].
Moscow and Jakarta also agreed on the methods of payment for the 11 Su-35s: 50% of the amount will be offset by the supply to Russia of local products, mainly agricultural goods, including palm oil, but also rubber derivatives, footwear, paper, resins, plastics and products for the defense industry.
The delivery of the client’s aircraft was to be completed within two years from the date of signing the contract in two separate phases: 8 Su-35s in the first year and three in the second year.
Early last year, TASS reported that Indonesian authorities had abandoned all plans to acquire the Su-35 due to US pressure, threatening to sanction Jakarta with the help of Countering America’s Adversaries Through the Sanctions Act [CAATSA].
The phased array antenna does not need to be rotated. The beam is directed within 120 degrees simply by phase shifting of the emitters.
Consists of many individual transceiver modules, each with its frequency and phase. It emits many beams at many frequencies at the same time. Due to the use of different random frequencies and constant frequency switching, it is difficult to detect against the background of the general background. It is difficult to suppress using electronic warfare due to the constantly changing frequency. Can be used passively to locate the source of interference. More reliable, since the failure of one or the other module does not matter.
An active array in a compact design requires a large number of powerful microwave transistors, at least gallium arsenide, modern radars – gallium nitride [the power is an order of magnitude higher]. The latest technology is poorly developed in Russia.
Russia uses PESA radar. This radar has one large powerful oscillator and many phase shift modules. Passive emitters. One beam at one frequency at a time.
