HII’s GRIMM™ and VIPER® Gain Awardable Status in DoW CDAO Marketplace
HII•HII’s Mission Technologies division secured awardable status for its GRIMM™ and VIPER® products via the DoW’s CDAO Tradewinds Solutions Marketplace, enabling streamlined procurement. GRIMM delivers compact spectrum dominance with real-time geolocation, while VIPER provides high-resolution RF channel emulation to support AI-based EW and counter-UAS training.
1. Awardable Status Secured
HII’s Mission Technologies division achieved awardable designation for two products in the DoW’s CDAO Tradewinds Solutions Marketplace, marking them as ready-to-deploy solutions for government procurement. This status accelerates access for defense customers and reduces procurement barriers.
2. GRIMM™ Spectrum Dominance Solution
GRIMM™ is a compact, high-performance payload engineered for real-time geolocation and direction-finding of adversary signals. Designed for low size, weight, power and cost, it enhances situational awareness, intelligence support and force protection.
3. VIPER® Electromagnetic Modeling Engine
VIPER® (Volumetric Integrative Propagation Engine for Ray-Tracing) generates realistic RF scenario data as a high-resolution channel emulator. It addresses AI data scarcity in Cognitive EW and counter-UAS applications while reducing costs and risks of live-fly testing.
4. Strategic Implications for HII
Awardable status on Tradewinds positions HII for faster contract awards and wider defense adoption of its AI/ML-driven EW technologies. Integration of GRIMM™ and VIPER® onto manned and unmanned platforms could expand HII’s addressable market and strengthen its defense pipeline.
