Swedish Project XXXX (1975)

[Hexelarity]

Does anyone have any information pertaining to the Swedish XXXX fighter; here is an image depicting what it looks like

Seems to be the same design as seen here in pre-Gripen studies topic:

The Rb.72 AAMs on the wingtips confirm an earlier date for this drawing - the Rb.72 AAM was cancelled in April 1978.

The XXXX looks to me like a not-so-distant ancestor of Boeing's just-selected TX contender (it doesn't have a real type name yet as far as I know), on which they partnered with Saab. If there's a real design lineage here, it went dormant for 40 years which must be some sort of a record.

Possibly by way of the Project 518 Eurotrainer, which has a similar planform (including the LERX not seen in the XXXX) but a single tail.

The design reminds me of some British projects from the 70's, mainly the P.110. Did BAe have any influence over this design? I know that at that time, they had been working together on what became the Gripen.

Not beyond the realms of possibility.
