Don't forget most ammo bays were lightly armored as well, so that a lucky round would not damage your guns or ammo belts.

shame that plane was grounded fron CV use 4 times,till the brits showed us ho to use the

Actually, now, we didn't need the Brits to "show" us anything. VF-17 proved the Corsair could safely operate off the carriers during combat operations as early as 1943. Keeping them land-based largely became a logistical decision of not having to keep the carriers supplied with spare parts for F4Us in addition to what they carried for the Hellcats.

Saying the F4u4 is underpowered is only part of it.


"As compared to what?"

The F4u-4 was mostly a post-war plane, and most of the post-war variants that served in Korea and as export planes for foreign nations had cannons.

F4u4s in WW2 did not.

Also, if you're saying it's underpowered in the engine department, again take a look at the extensive post-war career this plane had. You may be mixing up Korean power settings with WW2 power settings, or Soccer War power settings, etc.

I'm just saying that the f4u-4 was rated at 446 mph on the deck and it does more then 50mph less then that in the game

he last major wartime production variant of the Corsair was the "F4U-4", which featured a P&W R-2800-18W Double Wasp with 1,567 kW (2,100 HP) takeoff power and water-methanol injection. The only visible differences from the F4U-1D were an inlet fitted in the lower lip of the cowling, giving the aircraft's nose a slightly different profile, and a four-bladed propeller. All following Corsair variants would retain the four-bladed propeller. The F4U-4's engine and propeller gave it a top speed of 718 KPH (446 MPH), about 48 KPH (30 MPH) faster than the F4U-1D.

Where does it say this is deck speed? The -4 most certainly hits 446mph at its best altitude. Actually, she exceeds 450 at about 26,000ft.

You're confusing ground speed with speed on deck. Just because article says prototype achieved "an average ground speed of 405 mph" doesn't mean it could fly that fast on the deck. It just means it was measured on the ground. Same mistake is on Vought's website.

Ground speed = true airspeed - + wind speed

It doesn't say at which altitude, but it probably was around it's best.

Your right - that 446mph was at 26,200 ft.

XF4U-1 vs F4U-1, notice anything different besides all the things previously mentioned?

I couldn't because your enormous pictures broke the Aces High Forum...   :)

How could anyone notice something that fat and ugly next to the graceful lines of gull wings? ;)

That picture's a GREAT reference for the F4U's fabric wing surfaces, too. The prominent ribs you see on so many skins--and plastic models, for that matter--just doesn't exist.

Ah yes, that elegantly-shaped oval cowl can only mean one thing--sweet perfection.

Any idea where that picture was taken?

I recall being chased by a mustang in a -4. Long chase on the deck from one base to another. As I arrived I seem to remember that my airspeed was 405. I couldn't believe it. The prop pitch was fully feathered and I may have been using WEP.

That white thingie is the night vision pod

The white thingy on the wing is RADAR. That would make it the F4U-5NL.
