I have always been a keen advocate of increased F-22 production. Based largely on the fact that it would provide a better balance of fighters and lower unit costs.
I always thought the "F-15 will do" argument was short sighted given that when all fully retired in 2025 timeframe, nothing will be in production (other than the F-35) to replace them. Granted, the F-35 provides a large increase in capability over the F-15 but the US's edge may be lost when relying largely on the F-35, especially in 2025.
However, it's good to see that the money will be diverted into a surge of very rapid initial F-35 production. Lowering initial unit costs of the F-35 is paramount and this will give it the boost it needs. I also, don't see job loss as a concern, given that the F-35 is an LM product and therefore many employees could be transfered. The only issue would be geographically.
It is just a shame that the money had to be found at the cost of the F-22. Personally I feel that programs such as the V-22, EFV and some components of the excessive FCS program, should have taken a backseat to the F-22.
With regard to the RAF's use of F-35s and Typhoons, I believe that this is where a split tranche 3 schedule would come in handy. Once the F-35 is in RAF service any weeknesses or strengths found in the F-35 would help inform a decision on a final typhoon buy.
