“BAE Systems… today announced a critical program milestone with the successful insertion of new technology into its EW systems for the global fleet of fifth-generation F-35 Lightning II fighter aircraft”, the release said.
Upgrades to the AN/ASQ-239 will position it to meet future capability requirements and improve warfighters’ ability to conduct critical missions in contested airspace, BAE Systems said.
The improved EW system delivers the functionality of the previous system in a smaller footprint, reducing volume and power requirements – creating space for Block IV modernization upgrade… [and] also resolves issues with manufacturing obsolescence”, the release said. The ASQ-239 system provides fully integrated radar warning, targeting support, and self-protection capabilities to engage, counter, jam, or evade threats to improve survivability and mission effectiveness, BAE Systems said.
Other notable setbacks included issues with the Autonomic Logistics Information System (ALIS), a computerized maintenance tool that functions as the fleet's management backbone, and "unacceptable" accuracy in weapons systems used in air-to-ground.
