About this file
The document is a Draft Technical Specification for a B-52 Hybrid SATCOM Demonstration, detailing a L3Harris Hybrid SATCOM System terminal with specific technical specifications. The terminal is a GetSat Slingblade Ka LW mobile terminal located in Salt Lake City, Utah, operating in the Ka-band frequency range (29.0-31.0 GHz transmit, 19.2-21.2 GHz receive) with a 4-port circular polarization feed assembly. Key technical features include an AESA antenna with a 13.5 dBi/K G/T, maximum linear and saturated EIRP of 49.0 dBW, and a L3Harris RASOR modem capable of 45 Mbps data rates.
The technical specification outlines planned network connectivity across multiple Air Force bases, including demonstrations at Salt Lake City (8/4/2025 - 8/22/2025), Eglin AFB, Florida (9/22/2025 - 9/26/2025), and Barksdale AFB, Louisiana (10/27/2025 - 10/31/2025). The system will use Single Channel Per Carrier (SCPC) with 99.5% link availability, transmitting 1000 Kbps data rates. The demonstration is part of a pre-solicitation (Solicitation Number: FA2541-25-013) by the Air Force Research Laboratory seeking commercial satellite communication transponded capacity and ground station services for a hybrid SATCOM system.
