But it's told by Tucker, we see in First Flight that he was assigned directly to the Warp 5/NX Programs under Archer.
The episode makes it clear there's one high warp engine in development. They need it to succeed, as they say that going back to design a second engine would take decades, there aren't any competing ones in progress.
The episode paves over Daedalus, and the Romulan War books continue the trend by having the Warp 5 program be the only one, the Daedalus class limited to warp 2 structurally, and mentioning the Warp 7 program is limited by them only having experimented with M/AM drives.
Best to just ignore some of the earlier novels based only off season 1 and the first half of season 2, as everything after that ignores them anyway.
