Missing stock vehicles

[Youre_avarage_Kerbal]

where's the Aeris 1 and 2? Albatros 1 and 2? Ravenspear Mk2?

Why are they missing?

Maybe because they are way too old? Or maybe because old and not up-to-date vehicles get scapped!?

I don't know. I was there when the first stock crafts were added, there were no Aeris 1, 2, etc. Its just the name. You could make them yourself.

Check your .craft files. You may need to re-download them.

Pretty sure there never were any Aeris or Albatross 1s and 2s.

I don't remember on the Ravenspear.

Since the start, the Ravenspear Mk2 was missing for me.

The Stearwing D45 was removed from game a few versions ago.  The only stock two stage spaceplane, it had some aerodynamic problems that always made it hard to fly, and by later versions was completely unable to make orbit.

I tried to reinvent the craft, it suffers some appearance changes but can actually reach Minmus if flown correctly

I can confirm that the crafts listed by the OP have not existed since at least .235, and may've never existed, considering that was August of 2013.
