F-35C SpeedBrake-Ailerons? Rudder, Front & Rear Flaps
Looks like the F-35C uses ailerons as well as rudders and leading- trailing edge flaps for speedbrake - or do I see this photo incorrectly?
“On the F-35, speed brake functionality is provided through the use of the rudders & leading- and trailing-edge flaps.”

In an interview between John Beesly and Code One magazine, 15 Jun 2007, I'm guessing that the FLCS directs the rudders to rudders deflect outwards on the A & B, in conjunction with LEF/TEF actions mentioned here. Here's the quote from the article. I tried to link but I got "invalid session" error.
"The F-35, like the F-22, doesn't have a dedicated speed brake like most previous fighters. Instead, it decelerates through the flight control software by deflecting control surfaces in the same manner as the Raptor. We use the leading-edge flaps as well as the trailing-edge flaps and the rudders to slow the airplane. Unlike the F-22, the F-35A and F-35B have no ailerons. That explains why it uses a combination of leading- and trailing-edge flaps and rudders to slow down."

Same 'jetnerd' reference copy/pasted (thanks): "On Flight 7, we evaluated the speed brake operation. The F-35, like the F-22, doesn't have a dedicated speed brake like most previous fighters. Instead, it decelerates through the flight control software by deflecting control surfaces in the same manner as the Raptor. We use the leading-edge flaps as well as the trailing-edge flaps and the rudders to slow the airplane. Unlike the F-22, the F-35A and F-35B have no ailerons. That explains why it uses a combination of leading- and trailing-edge flaps and rudders to slow down. I found that the buffet levels were very low, essentially the same as buffet levels of the F-16 with the speed brake in operation. Deceleration rates in the F-35 are similar to the F-16 as well, which is a design goal."

UH, Well then I'll imagine that your Sluffing Super likely accelerates equally well with the giant single engine?
Completely OFF Topic and Counter Intuitive but relevant in the sense that some people argue the opposite - so this is for the FutureStealthySLUF squabbles:

Because it is not easy to find (NATOPS) Limits for some current USN aircraft here are the WOD limits (including Deck Pitch) for the T-45C Goshawk. Note that only a foot in Deck Pitch height separates the Students from others using the T-45C:
