Bye Bye Prowlers

I should probably have planned this post better and timed it to coincide with the actual event but that didn’t happen.  The Marine Corps recently retired their last EA-6B Prowlers and the web was full of shots of Prowlers to celebrate the event.  I like the Prowler a lot so I thought I would get in on the act.  I have shot Prowlers a bunch of times over the years whether it was on flight lines, on exercise, during training or at an air show.  Here is a selection of some of my favorite Prowler shots.

What Goes On These Pylons?

An older generation of Learjet was heading out from Boeing Field.  I almost ignored it but I got a few shots as it rotated and climbed out.  As it did so I noticed it had a pod on an underwing pylon.  A little further research shows it belongs to Phoenix Air.  Apparently, they have a few Learjets that have electronic gear fitted – sometimes on pylons and sometimes internally.  This pod appears to have dielectric elements front and rear so may well be an EW pod of some sort.  I wonder if anyone knows more about these guys and what they would be up to.

Dormant Centerline Jammer

The Growlers use the same jamming pod that came from the Prowler.  A new jamming system is in development but, for now, the ALQ-99 is the system that they have and the pods are the same pods.  The jamming power comes from a generator that is powered by a turbine mounted on the front of the pod.  As the jet flies along, the turbine spins in the airflow and provides the “juice” to power the electronics within.  Even at relatively low speeds the turbine gets rotating.  However, when the jets come in to land, if they have a centerline pod, the turbine is not moving.  I don’t know whether the blockage from the nose gear doors is enough to stop it or whether it is deliberately switched off.  However, the turbine blades are feathered and it is not moving.  Compare the wing mounted pods and the motion and blade angle is clearly different.
