Generational exchange is due to take place in the mid-30s. In this way, Singapore's combat aircraft fleet will decrease from 3 types to two. The F-35A and B are very different machines, but nevertheless have a large structural similarity. Singapore presently has a fleet of 40 heavy-duty F-15SG multi-purpose aircraft, which are comparatively fresh and were delivered in 2009-2018. They are a multi-tasking version of the F-15E Strike Eagle and represent 1 of the highest F-15 standards presently in operation in the world.
