We pulled out the batteries and APU from the aft fuselage which removed a lot of weight far aft of the center of gravity so we needed to balance out the nose heaviness. So, purely for CG reasons and nothing else, we were
forced to install the Martin 250CE top turret...
Out came the turret from storage which is sort of new old stock and still has cosomline on the armor plate. Its dusty but is really in good shape. It powered up and runs too.

Then the plug over the turret well on the Harpoon needs to come off





A sun roof?

We mooched a couple of guns from another turret in the museum until we can get the replicas purchased and installed. Hefting 60 pound guns inside the fuselage up to the turret when it is installed is not a lot fun so lets get them in place while the turret is on the ground.

The coolest part of this whole turret project for me is using the original equipment and tools. Any excuse to fire up the C-2 Wrecker truck. I'm sure there is some kind of a service conflict by using an Army Air Force truck to put a turret in a Navy aircraft but what the heck. Too cool:

Larry and Ricky are guiding the installation and are having almost as much fun as I am

Backing a 40,000 pound, 67 year old wrecker truck up to the Harpoon with 67 year old air brakes (we did rebuild them) is a bit intimidating. This trucks top speed is something like 27 MPH it is geared so low so it could back through the fuselage without much hesitation. No pressure...

A Lockheed Martin turret sling/frame was another cool original tool that sure came in handy

Next is fitting the new turret dome. There is a lot of trimming and fitting the dome to the turret. Only about a dozen trips with the dome back and forth from the top of the fuselage to the shop made me realize that next time I will fit the dome when the turret is on the ground. The dome will have to come off again for more trimming as there is still a conflict with the full elevation which didn't show up until the dome was bolted down. Azimuth is good though.


Here is the inside view. The turret matches our vintage interior very nicely

After wiring up the power to the turret the fairing can be installed and secured and there you have it: one Martin 250CE installed. Looks pretty darn cool.
