some of those German aircraft are quite scary

Had germany waited about 10 years to start the 3rd Reich,
they could of assaulted NYC with an aerial blitzkreig

The XF-85 Goblin. It was intended to parasite on the B-36 Peacemaker, but it didn't work out so well.

Looks like someone took the term "Fighter-bomber" a little too literally.

Or this one, the JB-17, single turbine-powered B-17 test bed.

B-17 nut that I am, I'm getting carried away...

Chuck Yeager flew chase on the Goblin test flights. He pulls zero punches in his assessment of the failure, laying blame squarely on the test pilot.

I love that. There's just something about the idea of mounting guns on an aircraft that recoil substantially enough to affect the flight characteristics. Had we sold this to the Russians the eastern front might have been quite messier. All in all a very russian engineering concept.

For it's lines that JB-17 is one of the prettiest aircraft I've ever seen.

IIRC that's a 40mm Bofors in the nose of that Lightning. Also, didn't they try to make a ship buster by putting a 105mm in the nose of a B25?

Also, a bit of trivia. What was the first piston-powered aircraft to exceed 500mph in level flight? (hint, it wasn't a P-51)

Brad, that is a B-25 in French G.'s post. It looks like one of the variants with a 75mm. 105mm were installed, too, as field expedients in the South Pacific. I forget who did the initial work on those.

ETA: Ah, yes, Major Paul I. "Pappy" Gunn was one of the first to do the field-expedient mods in the SouPac.

The B25-G and -H models came with cannon from the factory.

Brad, I'm thinking the P-47 Thunderbolt was the first that exceeded 500mph, but that might have been in a dive. Level flight, I dunno...

I do know they had severe compressibility issues with the P-38 in high speed dives. Same thing happened to the P-47. They lost a bunch of them during WWII, not really knowing at the time what they were up against.

Brad Johnson · « **Reply #17 on:** February 25, 2009, 01:41:39 PM »

Sorry, I had a crack moment when I called it a Lightning. Not even a close similarity. It's even more embarrassing because I love warbirds so much. Duh.

And that, kids, is why you shouldn't post and talk on the phone at the same time.

P-47 is right, though it wasn't a production version. It was the P47J, a radical experiment using a tightly cowled hotrod version of the Pratt R2800. Although it looked similar to a production P47 it shared virtually none of the production version's airframe components. It reached 504 mph. I understand there were also experiments with the largest production engine available at the time, the Pratt & Whitney R4360 Wasp Major, but it was deemed waaaaaay to large and heavy. (Chance Vaught also experiemented with this engine in it's Super Corsair tests).

My Dad told me during WWII he had an opportunity to ride along in a B25 armed with a 75mm gun. He said when it fired, it felt as if the plane had collided with something.

I don't recall that he ever mentioned a 105mm being mounted in one, field expedient or otherwise.

As for bigger engines, there's this monster, the Lycoming R-7755.

I could be mistaken, HankB. I cannot find references to it in my library. The 75mm variants are coming up all over the place.
