On September 12, 2019, Congress was notified by congressional certification transmittal number 0Q-19 of an increase in capability from the Navigation Sensor System Interface (non-MDE) originally notified to the Global Positioning System (GPS)-based Positioning, Navigation, and Timing Service (GPNTS) capability, which is MDE. The total value of the GPNTS was $3,417,596, but the total estimated MDE cost and the total case program value remained the same at $.375 billion and $2.150 billion, respectively.
On December 14, 2023, Congress was notified by congressional certification transmittal number 23-0V of the following MDE items: two (2) AEGIS Weapon Systems; two (2) AN/SPQ-9B Radar Systems; two (2) AN/SLQ-32(V)6 Electronic Warfare Systems; two (2) AN/USQ-140 Multifunctional Information Distribution System (MIDS) on Ship (MOS), Modernization (MOS MOD); two (2) AN/USQ-190 Multifunctional Information Distribution System Joint Tactical Radio Systems (V5); three (3) Cooperative Engagement Capability (CEC), AN/USG-10s; and one (1) AN/UYQ-120(V) Command and Control Processor (C2P) Technology Refresh System. Also included were AN/SQQ-89 Underwater Sound Equipment Systems; Multi-Function Towed Array Systems; RT-1829 Ultra-High Frequency, Satellite Communications (UHF SATCOM) Terminals; OE-570D Antennas; MK20 Mod 1 Electro-optic/Infrared Sensor Systems; MK160 Mod 23 Gun Weapon Systems; MK-36 Mod 6 Super Rapid Offboard Countermeasures and Decoy Launching System (SRBOC); U.S. Government and contractor representatives technical, engineering, and logistics support services; installation support material; training, tool development, communications equipment, and associated spares; classified and unclassified publications and software; and other related elements of logistics and program support. The estimated total value of the new items was $0.570 billion. The net MDE value increased by $0.239 billion and the non-MDE value by $0.331 billion. The revised estimated total case value increased to $2.72 billion. MDE constituted $0.614 billion of this total.
This transmittal notifies the addition of the following non-MDE items: medium range ballistic missile live fire test targets; short range ballistic missile live fire test targets; additional AEGIS Weapon Systems components, spares, tech documents, and software required for use at Japan's computer test site; additional U.S. Government and contractor representative technical, engineering, test and evaluation, and logistics support services; installation support material; training, tool development, communications equipment, and associated spares; classified and unclassified publications and software; and other related elements of logistics and program support.
