Rostec State Corporation supplied domestic spark plugs for SaM146 aircraft engines, a fact highlighted by company communications. The SaM146 powerplant is installed on the Sukhoi Superjet 100, and the shift toward homegrown components has grown increasingly urgent as Western sanctions intensified. The push to source critical parts locally emerged as a strategic response to disrupted collaboration with foreign partners and the broader challenge of import substitution facing the Russian aviation sector.
Industry officials note that the move to replace imported parts with domestic equivalents began amid tightened restrictions and the need to safeguard transport security. Vladimir Artyakov, the first deputy general director of Rostec, emphasized that rapid efforts were launched to substitute key components, including spark plugs, to ensure the reliability and continuity of essential air operations within the country. This stance reflects a broader policy goal of maintaining aviation capability and resilience in the face of external pressure.
The production of new spark plugs for the SaM146 engine was commissioned by UEC-Saturn, with manufacturing responsibility assigned to the Ufa Aggregate Production Association. The initiative reflects a coordinated effort across the Russian defense and industrial sectors to sustain critical supply chains while reducing dependence on imports for high-demand aviation equipment.
Prior to these developments, Rosatom engineers contributed to the domestic market by developing specialized rope cutting equipment. This equipment was designed to meet the needs of Russia’s industrial base, illustrating how aerospace, energy, and manufacturing entities intersect to strengthen national production capacity and technical self-sufficiency.
The backdrop to these advances includes ongoing concerns about international restrictions and the evolution of sanctions policies that have influenced procurement strategies across the aviation and manufacturing ecosystems. The focus remains on ensuring that domestic capabilities keep pace with evolving global conditions while maintaining safety, performance, and reliability in Russian aviation hardware.
