Hmm... maybe Bogdan was thinking of that graphic when he mentioned the possibility of adding a second missile to the by door? :wink:

I thought there was talk a number of year's ago - Aviation Week? - where there was a discussion of increasing the internal weapons load. The best I could find is a reference to the USAFRL saying that the F-35 could carry 12 missiles internally - divided between the two bays.

I think someone else on this forum mentioned it, but I will mention it also. Why can't the F-35 carry 8 per bay - one on each door and two where the SDBs are mounted?

12 missiles internally refers to the Small Advanced Capabilities Missile (SACM), also known by it's Lockheed entry named CUDA (Raytheon however has so far been the victor of the SACM R&D funding competitions). A SACM is designed to be half the length of an AMRAAM; as such you'd fit 2 where you can fit 1 AMRAAM or 1:1 for where you can fit a Small Diameter Bomb.

As for why 8 isn't possible; it's a matter of space and separation safety - it's unlikely you could fit 8 internally (that fan art earlier in the thread is wrong about the size of the bays; they're scaled up in that image). But even if fitting 8 AMRAAMs was possible, you have the issue where if a missile on the outer door (today AMRAAMs are carried on the inner doors) failed to launch / eject, you've now blocked at least one (very likely both) of the two AMRAAMs that sit on stations 4 and 8 (where internal bombs normally go).

Also, note that those compartments also have pipelines, wiring and various other gadgetry. It's not spacious in there...

Wait, that’s a missile on each of the four doors? I thought that wasn’t possible.

:devil: It is CGI where the aircraft MAY NOT be an F-35B on a future LHA (see ersatz deck Island) with an HUD goldarnit! :doh:

I'm rewarding myself a cookie for calling that years ago if that configuration proves to be accurate in the future. Less separation issues if the 3rd missile per bay is mounted on the outer bay doors.

I know that I am probably just seeing things, but it does look like the ones on the outer doors are smaller than the ones on the inner doors. . . . . and the ones on the outer doors are the same size as the ones under wing. Is there a way to put a rail mounted system for AIM-9x on the outer door?

I understand it is CGI -- quite pretend. It did spark the question " Is there a way to put a rail mounted system for AIM-9x on the outer door?" I imagine someone here has a reason why it would not be possible, and I would like to learn from that answer.

Years ago there was a forum thread about such a question. Some TRAP EASY info from 'SWP':

viewtopic.php?f=22&t=24350&p=256283&hilit=rail+door+trapeze#p256283

Use the search text string: +rail +door +trapeze for more....

So what's the real story? Are 6 Internal AMRAAMS no longer even on the radar for Block 4?

Seems like hypotheticals all around until someone commits to pay for it. I wouldn't be suprised if USAF at least is priortizing funds for SBD II integration.

Yes they are, just not attached to the outer doors.

The cost of SDB2 "integration" into the F-35 will depend on one "which cam first, the chicken or egg" factor. SDB2 is already part of UAI so if UAI is concurrent with SDB2 in the F-35, then it will be cheap and quick. If UAI comes after they want to have SDB2 integration, then it will be more substantially expensive, in money and time.

The LAU-147 are attached at the hinge, Bogdan’s statement about the possibility of a second pair on the weapons bay door was vague. Adding a second launcher in the bay looks to be tight unless there is a modification for a double launcher fitted to the A-G attachment point. The outer door hinge is clear, but looking at this picture, there might not be the depth.
Any other information on this?
