k**0 发帖数: 1 | 1 Another major weakness of the F-35 project is the “Autonomic Logistics
Information System” (ALIS), which remains the property of the manufacturer
Lockheed Martin and is operated by them worldwide. ALIS is a complex
computer system consisting of 65 individual programs with 16 million lines
of code that continuously collects and analyzes aircraft data. It is used,
among other things, for resource planning, threat analyses, maintenance
diagnoses, and planning, and for ordering spare parts. All F-35s, including
those from partner countries or buyers outside the US, must update their
mission files and ALIS profiles before and after each flight. For this
purpose, the data from each F-35 is downloaded, then it is first
electronically sent to the ALIS mainframe in Fort Worth, Texas, which then
forwards it to the USRL and Lockheed Martin. From there, the updated data on
the mainframe will be transferred back to all F-35s, even overseas. If the
Internet connection from the US to Europe, for example, is interrupted by
cyber attacks on network nodes or sabotage to the underwater cables, the F-
35s cut off from ALIS, e.g., in Great Britain, Italy, and Turkey, will
remain on the ground until further notice (Giovanni de Briganti, “US
Software Stranglehold Threatens F-35 Foreign Operations“, Defense-Aerospace
.com, 11/04/2015). Data transmission via satellite is hardly possible due to
the high data volume requirements of only one F-35 squadron, as tests on
board the aircraft carrier USS George Washington in August 2016 demonstrated
. It took two whole days, among other things due to tactical radio silence,
limited bandwidth, and poor satellite connections, to send a 200 MB ALIS
file. It remains to be seen how these transmission problems will be solved
in the future when stationing entire squadrons of F-35 “B”/”C” models on
carriers and amphibious attack vehicles. The DOT&E called on the USN to
further investigate this matter. | d**********r 发帖数: 24123 | | xt 发帖数: 17532 | |
