The United Engine Corporation (UEC) showcased its cutting-edge developments in aero-engine design and defence industry technology at Aero India 2025 in Bangalore. Participating in Aero India enables UEC to introduce prospective Russian developments to a wide range of international stakeholders, consolidate its position in the Indian market and expand its export opportunities.

Making its international debut is the UEC’s latest innovation – the VK-650V turboshaft engine, which has completed certification and is ready for series production. This engine is designed for installation on the Ansat and Ka-226T helicopters. The VK-650V’s modular design simplifies its maintenance and repair. It is anticipated that the introduction of the VK-650V will enhance the competitiveness of Russian helicopters in the international market.

Also on display at the UEC stand is the fifth-generation 177S engine, designed for tactical aircraft. This powerplant delivers increased thrust and boasts an extended service life of up to 6,000 hours. The 177S engine has been developed using state-of-the-art technologies aimed at improving fuel efficiency and reducing operational costs.

UEC first presented the 177S engine in November 2024 at Airshow China. It has a thrust rating of 14,500 kgf, with fuel consumption reduced by at least 7% across all regimes. By relaxing service life requirements, thrust can be further increased to meet the demands of fifth-generation aircraft. The UEC’s stand at the Zhuhai Airshow featured photographs of the 177S engine in association with the Su-57, and considering that the Su-57 was also marketed in an export version – the Su-57E – it is possible that this power unit is intended specifically for this aircraft.

Furthermore, in India, the UEC is showcasing the AL-55E engine, specifically developed for the Indian HJT-36 intermediate jet trainer. The engine was designed at UEC-Saturn and is produced through a collaborative effort between UEC-Saturn and UEC-UMPO. The powerplant features a modular design, ensuring high manufacturability and low operating costs, while a modern digital control system guarantees flight safety and ease of maintenance. The engine has a maximum thrust of 1760 kgf.

As part of the Aero India 2025 exhibition, Russia is also demonstrating the Su-57 fifth-generation fighter and the Lancet loitering munition. On the first day of the airshow, Sukhoi Design Bureau’s chief test pilot, Sergei Bogdan, showcased the Su-57’s aerobatic performance to the Indian public, military personnel and international attendees. UAC presented this flight both from the ground and from the aircraft’s cockpit.

The Lancet loitering munition is designed to engage a wide array of targets, both on the ground and in the air. This kamikaze drone is equipped with an electric motor and twin X-configured wings. It employs an inertial navigation system for autonomous guidance and also features the option of optical guidance via an operator.

In addition to aircraft and related technology, Rosoboronexport presented air defence systems at the exhibition, including the S-400 Triumf and Tor surface-to-air missile (SAM) systems, as well as a broad spectrum of missile armament. In particular, the R-77-1, R-37M, Kh-35UE anti-ship missile and Kh-69 low-observable cruise missile are on display. This wide range of presented products underlines Russia’s commitment to strengthening military-technical cooperation with India and other nations in the region.
