Russia is taking its export fighter to the Egyptian coast next week, and it is bringing something it has never shown anyone.

Rostec, the Russian state defence conglomerate, says the Su-57E will fly at the El Alamein International Airshow from 8 to 10 September carrying weaponry that has not previously been displayed publicly — not in Russia, not abroad. It will also fly an aerobatic routine.

Rostec has not said what the weapon is. That is, of course, the point of the announcement.

What Rostec is claiming

The company’s statement is a sales pitch wrapped in a combat record, and it is worth reading in full because the wording matters.

Note what is not there: no weapon designation, no named customer, no delivery numbers. Rostec says deliveries to foreign partners are under way but does not say to whom.

The customer nobody will name

Algeria is the answer everybody assumes. Algerian state television showed footage in February 2025, and in November 2025 United Aircraft Corporation director general Vadim Badeha said two Su-57Es had been delivered to an unnamed foreign partner. Neither Moscow nor Algiers has ever jointly confirmed it.

Rosoboronexport has separately said it signed further Su-57E export agreements at the DSA-2026 exhibition in Kuala Lumpur in April, again without naming countries or numbers.

This opacity is not accidental. Buying Russian combat aircraft now carries the risk of U.S. sanctions under CAATSA, and the quieter a customer keeps it, the longer the awkward conversation can be deferred.

Egypt has walked away before

Which makes Egypt an interesting place to hold this particular demonstration. Cairo agreed to buy around 30 Su-35s, then halted the deal in 2021 and 2022 over exactly those sanctions concerns — after Russia had already built roughly a dozen aircraft. Some of those jets were later reported to have been redirected towards Iran.

Egypt has since gone in a different direction. It flies Rafales, has just asked Dassault for 24 more, and hosted Chinese J-16s and a Chinese Y-20 tanker during the Eagles of Civilization exercise. The Egyptian market is genuinely open — and Russia is no longer the obvious winner in it.

A full Su-57 aerobatic display, filmed at Aero India 2025 — the kind of routine Rostec is promising at El Alamein.

What might the weapon be?

Nobody outside Rostec knows, and we are not going to guess a designation. What can be said is what the Su-57E’s export marketing has emphasised so far: internal carriage of air-to-air and air-to-surface weapons, compatibility with a broad Russian munitions catalogue, and a steady stream of incremental upgrades aimed at customers who want a fifth-generation aircraft without an American export licence attached.

Something genuinely new on the pylons — or, more interestingly, in the weapons bays — would be a real signal. Something repainted and relabelled would not be the first time an air show reveal turned out to be less than advertised.

We will know between 8 and 10 September.
