Russia’s Roselectronics claims to have made a breakthrough in low observable materials, with a composite capable of absorbing a wide range of radar frequencies.

The company, a unit of state arms manufacturer Rostec, says the lightweight material is composed of glass fibres with a metal core, and is suitable for the manufacture of aircraft parts.

“In the process of creating a radio-absorbing material, several layers of fiberglass were connected to each other,” says Rostec.

“It is based on thin threads with a metal core in glass insulation. Due to its exceptional characteristics, the new material absorbs up to 95% of the incident electromagnetic radiation of radars and significantly complicates the detection of an air object using radar equipment.”

Rostec adds existing stealth coatings require regular restoration, while its new material requires no maintenance.

Rostec makes no mention of whether the new radar absorbent material will be incorporated into the Su-57, or into the developmental Su-75 Checkmate.
