About this file
This memorandum from the 39th Electronic Warfare Squadron (39 EWS) at Eglin Air Force Base details technical requirements for a ruggedized Sensor Open Systems Architecture (SOSA) chassis. The chassis must be built to CMOSS and OpenVPX standards, designed for integrated front loading, and ruggedized to meet MIL-STD-810G and MIL-STD-461C environmental and electromagnetic compatibility specifications.
The chassis requires a 100 GbE backplane with 7 specific card slots, including a 600W power supply, dual enclave Ethernet switch, position navigation and timing card, single board computer with 128GB RAM and 2TB SSD storage, and a general-purpose GPU card capable of 10-17 TFLOPS. It must support multiple external interfaces such as power connectors, network ports, transceiver signal ports, zeroize switch, and various specialized connectors for GPS, PNT, and RF blocks. The VPX backplane configuration includes 4 dedicated CMOSS payload slots, 1 timing slot, 1 Ethernet switch slot, and 1 VPX power supply slot, with power input compatibility for MIL-STD-704, MIL-STD-1275, and DEFSTAN 61-5 standards.

MEMORANDUM FOR PZIOA
FROM: 39 EWS
SUBJECT: Ruggadized SOSA Chassis
1. Technical Overview
The 39 EWS is in need of an integrated ruggedized Sensor Open Systems Architecture (SOSA) chassis built to
CMOSS and OpenVPX standards. The chassis needs include any support equipment that would enable the seamless physical and network integration of 3U VPX/SOSA aligned RF transceivers. The chassis needs to have the integrated cooling required for conduction cooled cards. The chassis needs to accept MIL-STD-704, MIL-STD-1275, and DEF-
STAN 61-5 power input options.
