In an unusual co-incidence both the DDS Aviation Service and the HCSAF announced at media briefings they are working on new fighter projects to replace their current front line fighters in the 2120s (the DDS were first, it is thought the HCSAF bought their announcement forward a few days).
The DDS project has been named as ADF (Advanced DDS Fighter) and will replace the F-10S as front-line fighter (and replace the F-10A in totality) in the mid-2120s. It will be a highly agile, stealthy fighter of course. Some design studies published show a hybrid of F-10S and the HCS F-45 which would make for an interesting type! This project replaces the previously announced (but scant detailed) F-10X. Also at the briefing the DDS announced that the light attack aircraft currently in development, the NDAA, will be known as the A-12 in service.
The HCS project is called NGCA (Next Generation Combat Aircraft) and is expected to enter service in the early 2120s (so before the ADF). This will replace remaining F-40s in HCSAF service. Details of NGCA are being kept under wraps for now, one rumour is that it will be an advanced development of the F-45, a design said to have a lot of life left in it.
