Radar MMS Production Company, specializing in the development and manufacture of unmanned aerial vehicles, has initiated another arbitration proceeding against JSC Instrument Design Bureau (KBP). The amount of the claim is 17.1 million rubles. The Tula enterprise is part of the state corporation Rostec structure — through the High-Precision Systems holding — and is known as the lead developer of the Pantsir-S1 anti-aircraft missile and gun systems.
The circumstances of the case are still unknown, but this is not the first legal dispute between the two participants in the defense-industrial complex. In 2025, Radar MMS applied to arbitration with a similar financial claim against KBP in the amount of 40 million rubles. In that process, the Russian Ministry of Defence acted as a third party, but the course of the case is currently suspended without a final decision being issued. In response, the Tula designers filed a counterclaim against Radar MMS for 2.5 million rubles, which indicates mutual claims within the framework of contractual relations.
According to analytics from the Rusprofile platform, in 2025 the enterprise acted as a defendant in 158 arbitration proceedings with a total value of 9.7 billion rubles. Since the beginning of 2026, the arbitration courts database has recorded another 15 lawsuits against the design bureau totaling 727.8 million rubles.
