Network appliances enabling distributed operational and exercise support between Active Component and ANG AOCs reached end of life 1 January 2021. The program office is executing a replacement plan but has not included ANG units, incurring risk to mission continuity and network security. This capability gap is independent from the Falconer Block 20 upgrade. Two appliances are required for each of 5 AOC locations to ensure redundancy and maintain parity with Active Component AOCs.
