ALIS Biggest Challenge For F-35 IOC: Gen. Harrigianhttp://breakingdefense.com/2015/09/alis-biggest-challenge-for-f-35-on-track-to-ioc-gen-harrigian/ Un commentaire: Don Bacon•a day agoALIS is the biggest challenge. The engine, the major software delays, the sensor problems, the mission data load shortcomings, the poor reliability and the aborted procurement plans are smaller challenges. Meanwhile the Air Force plans IOC next year with insufficient Block 2 software, which they are calling "Block 3i" because it is Block 2 running on an updated processor. Who's fooled by that? The original plan was full combat capability with Block 3, but the MC and AF decided that half a cup is better than none.
