Armor plate weight

Sat Jul 27, 2013 1:02 pm

Does anyone have an idea of how much weight protective armor added to the various fighter aircraft that used it? How about bombers as well? Aside from the pilot armor, in what other areas was it usually found?

In a P-51 the Firewall, fwd bulkhead of the cockpit/aft end of the engine area, is 3/8" thick steel plate side to side and top to the wing at the botto. (The rest is S/S from bottom cowl to the top of the wing and also behind the oil tank) It is a part of the structure so you keep it even today for most A?C. Some racers use a thin sheet of S/S on alum plate to replace it.
So not all the armor is removed, however we don't have the plate behind the seat and a smaller one under the windscreen.
The one behind the seat is thicker from the top of the seat up and thinner for the remainder down to the bottom of it.
On the mk 18 Spitfire it is around 3/16 / 1/4" thick steel plate and attached to the seat back and bottom of the seat. You have to remove the seat for maint and its heavy. There is a small piece behind your head. They also had small pieces front and rear of ammo in the wing, at least in our wing, but don't know specifics for other Spit models.
How much it weighs/ed I would have to look up. Each type will vary and probably different models of the same type depending on turret type, ect.

it was also in various areas of the b-17. I know on the one I work on, the top turret armor was 2 pieces and i believe 3/8 to 1/2 in thick and was extremely heavy. I'll ask the boss and get better numbers for you.

Corsair had armor plating behind the pilot. I believe when the au-1 was made for low level ground support, they added more to vital areas.

The B-26 Marauder had quite a lot of armor sections protecting the gunners and the cockpit. Also some in the nacelles covering, I presume, the carbs or other vital engine accessories. One of these engine sections still lies at a B-26G crash site in the Welsh mountains.

It was a bit too heavy and a long walk down! Back in the 1960s a friend and I carried a .50 machine gun back from the site and took it home in an MG Midget boot (trunk). We had some trouble disguising the protruding barrel :wink: . From the broken lugs on it it looked like one of the side guns. Sadly, the Snowdonia National Park authority had the engines and some other big bits such as the top turret area removed by helicopter in the 1980s.
