Interesting Photo Shows F-22 Raptor Landing At RAF Lakenheath With Open Missile Bay

This Is Something You Don’t See Too Often.

The photographs in this post were taken by our contributor Alessandro Fucito on Oct. 12, 2017. They show a U.S. Air Force Raptor jet, belonging to the 1st FW, Joint Base Langley-Eustis, Virginia, deployed to the UK, since Oct. 8, landing at RAF Lakenheath with the side weapon bay open.

The stealth multirole jet AF 08-154 is one of the six involved in a FTD (Flying Training Deployment) in Europe. The aircraft have just completed a tour of duty at Al Dhafra airbase, UAE, in support of Operation Inherent Resolve in Syria and Iraq.

Noteworthy, an AIM-9X Sidewinder can be seen inside the open weapon bay.

The latest variant of the Sidewinder missile is a recent addition to the F-22 Raptor inventory: the IR-guided missile has been integrated on Mar. 1, 2016, when the 90th Fighter Squadron (FS) belonging to the 3rd Wing stationed at Joint Base Elmendorf-Richardson, Alaska officially became the first combat-operational Raptor unit to equip an F-22 with the AIM-9X Sidewinder.

Most of US combat planes use the AIM-9X along with a Helmet Mounted Display since 2003 (by the way, one was fired at a Syrian Su-22 recently, but failed for reasons that are still unclear): with a HMD (like the American Joint Helmet Mounted Cueing System – JHMCS), information imagery (including aircraft’s airspeed, altitude, weapons status, aiming etc) are projected on the visor enabling the pilot to look out in any direction with all the required data always in his field of vision. The HMD enables the pilot to exploit the full HOBS (High Off-Boresight) capabilities of the AIM-9X and engage a target by simply looking at it.

However the AIM-9X will not be coupled to a HMD as the Raptor is not equipped with such kind of helmet that provides the essential flight and weapon aiming information through line of sight imagery as the project to implement it was axed following 2013 budget cuts.

In 2019, the Air Force plans to equip the F-22 with the AIM-9X Block II, the F-22 will probably fill the gap as the most advanced variant of the Sidewinder is expected to feature a Lock-on After Launch capability with a datalink, for Helmetless High Off-Boresight (HHOBS) at intermediate range: the air-to-air missile will be launched first and then directed to its target afterwards even though it is behind the launching aircraft.

This will not give the F-22 the same ability as an HMD-equipped aircraft, still better than nothing.

Back to the top photo, we don’t know the reason why the aircraft flew with an open weapon bay. Although the aircraft can take-off and land with the open side bays, it’s something that happens quite rarely and this leads to believe it might have been because of some sort of system fault that prevented it from being closed.
