F-35B flies external captive carry with Paveway IV and ASRAAM AIM-132

This article (H/T from reader Nico) has some exclusive images and one non-exclusive image.

It shows the first flying captive carry of an external F-35B configuration of 4 Paveway IVs (these are a dual-mode PGM) and 2 ASRAAM AIM-132. (click for photo)

The non-exclusive image is from at least as far-back as 2010. It shows the ASRAAM in a mock-up of an F-35 internal weapons bay.

Here is some of the history of integrating ASRAAM with the F-35.

What I wrote in 2009:



For some time, the U.K. has been expecting to carry 4 AIM-132s internally in the F-35. At least they were until this came in early 2008. (JANES link now broken EP) They couldn’t do the work by the end of SDD so it was decided that the goal for the U.K. F-35 program would be to have 2 internal AIM-132s and 2 external AIM-132s on  low observable pylons.
The original UK intention was to clear four MBDA Advanced Short-Range Air-to-Air Missiles (ASRAAMs) for internal carriage but this has been revised to include two internal and two external weapons instead.
The configuration change was agreed with the JSF Program Office in the United States late last year and was shown in public for the first time during the Singapore Airshow in February. The external ASRAAM fit will be common across all three JSF variants and could therefore attract interest from other international customers, who will otherwise be tied to Raytheon’s AIM-9X Sidewinder.
The new ASRAAM plan is a ‘work swap’ that does away with the requirement to clear the ASRAAM on the F-35’s two internal air-to-ground weapon stations. The integration team now has the more straightforward task of providing underwing carriage on stations 1 and 11. The ASRAAM is a rail-launched missile and internal weapons must be carried on a trapeze that swings down clear of the F-35’s weapon bay before they can be launched.
It has always been a credo of the JSF programme that external weapons carriage fundamentally compromises the aircraft’s very low observable (VLO) design. Speaking at the Singapore Airshow, George Stanridge, Lockheed Martin’s vice president of F-35 Business Development, noted that, in general, “if you see something hanging on the aircraft it means you are not a VLO airplane”. A new ‘stealthy’ pylon has been developed for the external ASRAAM and MBDA notes that the finless missile already has a tiny radar cross-section.
Carrying the ASRAAM outside the weapons bay brings several advantages, primarily in allowing passive long-range – beyond-visual-range (BVR) – engagements cued by the missile’s seeker or the F-35’s infrared search and track sensor.
Now though, even that bit about the stealthy pylons seems to be off the table. In this recent article by Bjørnar Bolsøy on F-16.net, we have words from LM that the stealthy pylons are unfunded.
Development of a stealthy air-to-air pylon has been brought up from time to time. This would allow for reduced signatures when carrying missiles on the wing stations. But the project appears to have been put on ice for the time being. O’Bryan informs that the project is currently not funded. What is being studied, however, is a 6 air-to-air missile capability in the internal weapons bays, which would substantially increase the F-35’s stealthy fire power.


So they got pylons now. Are they stealthy as planned?

It will be interesting to see when new photos appear of a successfully integrated ASRAAM AIM-132 in the internal bays (as per the original SDD requirement). That could be a big "if". As for the AIM-132, it is a good missile. Compared to the AIM-9, I don't consider it "short-ranged".

Here are some of the challenges with rail-mounted missiles and the F-35 weapons bays.
