Incapable to intercept enemy aircrafts in autopatrol.

As commented, but slightly better explained:

Employing the simple F-35A Lightining II Learning Curve scenario (GIUK Battleset):

The F-35 in patrol can't intercept or attack the Flankers in patrol in the Russian base, after detected at medium-long range by ESM.
When F-35 are ordered "to attack" the Russian base, clicking on the own F-35 group (pretending to attack the Flankers in autopatrol entouring Kaliningrad) the answers is "we have not weapons to attack a surface target", not giving the option to attack the aircrafts in autopatrol.
When ordered "intercept" the Russian base, cliking on the Russian base (pretending to attack the Flankers in autopatrol) the answers is the same: "we have not weapons to attack a surface target", not giving the option to attack the aircrafts in autopatrol.

Attached filed are scenario and savegame with the depicted situation.
