I have been looking at including these in the VBAM stats, the problem being that VBAM does not have them.
In version 22 of the shipyard I have included the following change for dual mode fighters.
If you use VBAM please take a look and let me know what you think.
In order to carry the one shot weapon the fighter is increased one level in most respects.
The book example of the "Short" fighter with a striker load:
Fighter with Interceptor trait (Small flight of 4)
(Lt) Cost:1/5 Maint:1/16 DV:1 AS:0 AF:2
Becomes as Dual Mode:
(SF) Cost:1/4 Maint:1/12 DV:1 AS:2/0 AF:0/2 (Before/After strikers
are used)
Size cost and maintenance increased by one level, Anti ship increased
by 2 for one shot only and Anti fighter reduced by 2 until weapon is
used.
