Cockpits!
For those who haven't seen what the fighters look like from the inside, here you go:
Lockheed Martin F-35 Lightning II
There's no doubt about it, the F-35's cockpit is the future. A wide, full color, touchscreen is the dominant feature. With touchscreen capability and countless features, the F-35's display will no doubt be just the thing for a generation of pilots used to iPads and smartphones.
There is no heads-up-display (HUD). Vital information is instead relayed directly onto the pilot's visor using the helmet mounted display, simulated in green in this picture. Using the F-35's sensors, the helmet mounted display can even allow the pilot to "look through" the aircraft.
Future concepts for the Saab Gripen and Boeing Super Hornet show a very F-35-like cockpit layout.
Eurofighter Typhoon
The Eurofighter Typhoon sticks with a much more conventional layout. Three large multifunction displays (MFDs) along the traditional HUD, buttons, and dials. The Typhoon's cockpit ergonomics has been praised by its pilots, however. A helmet mounted cueing system is utilized, as well as a voice control allowing the pilot to select targets or perform many other functions simply by voice.
Dassault Rafale
The Dassault Rafale's cockpit is... Well... Different.
It certainly appears clean and uncluttered, with a traditional HUD, side mounted stick, and 3 MFDs. For some reason, however, the two touchscreen side MFDs are located far forward, with the center MFD magnified by a lens resembling an old fashioned microfiche reader. It's actually a head level display (HLD) that displays information at the same focal distance as the HUD.
While the Thales TopOwl-F helmet mounted display would seem like a no-brainer for the Rafale, it has yet to be realized in operational form.
Boeing F/A-18E/F Super Hornet
In comparison to the others, the Super Hornet's cockpit looks like a blast from the past with its monochrome green displays and array of dials, switches and buttons. This picture is a bit deceiving, however, as it is quite a few years old, and the Super Hornet has gone through a few changes since then.
The newest proposed Super Hornet cockpit would look eerily close to the F-35's, with a wide touchscreen and a HUD replaced by a helmet mounted display.
Saab JAS-39 Gripen
The current Gripen C cockpit very much resembles the Eurofighter Typhoon workspace, three large MFDs with a traditional HUD. No real surprises here.
The proposed "NG" models of the Gripen, the E and F, will likely adapt a similar single large touchscreen as utilized by the F-35. Again, it eschews a traditional HUD in favor of a helmet mounted display. Without a doubt, this is where fighter cockpit design is going.
Lockheed Martin F-22 Raptor
For sake of comparison, this is what the current "king of the sky" F-22 cockpit looks like. Nothing groundbreaking here. Just MFDs, and a traditional HUD. The F-22 still lacks a helmet mounted display, as well.
