What would be classified as a proper rear gunner station?

First would be decent gunner arc in rear quarter. It is surprising that the SB2C Helldiver had such a poor rear gunner view, maybe the theory was the back seat gunner would call out to pilot to side slip so he could get a shot?

Second at least dual 0.30" or single 0.50" with ~150rd+ belt feed.

Third Some armour plate and glass for him!

They tried a turret installation on the SB2C but it was too heavy, for an already overweight aircraft.
 
The USN came to the conclusion that the rear gunner was unnecessary as seen in the single seater Skyraider and Mauler.
 
Saving the weight of a rear gunner and associated gun weight etc is an enticing reason to remove him, but in most cases the speed improvement would not be enough to have the light attack bomber escape fighters anyhow, its kind of a Catch-22 situation.

The Skyraider is a heck of a beast with a single B-29's 3000hp engine, and a bit outside my initial 2000hp ideas, the only other country to fully develop their light attack planes to their endpoint was USSR's Shturmovik il-2 then il-10 variation, interesting was they ended up with 12.7 then 20mm for rear gunner.

Marine Corps Skyraiders suffered heavy losses when used in low-level close-support missions. To allow low-level operations to continue without unacceptable losses, a package of additional armor was fitted, consisting of 0.25–0.5 inches (6.4–12.7 mm) thick external aluminum armor plates fitted to the underside and sides of the aircraft's fuselage. The armor package weighed a total of 618 pounds (280 kg) and had little effect on performance or handling.[14] A total of 128 Navy and Marine AD Skyraiders were lost in the Korean War – 101 in combat and 27 to operational causes.

A knew Mustangs and Corsairs fought in Korea but not much about Skyraider, I guess its no surprise Soviet AAA guns were effective after 4 years of WW2 development.
 
Getting rid of the rear gunner (and radio man) was probably more about increased payload (bombs or fuel) than increased speed.

I mean come on,

Forget the plane in the foreground, even the one in the back wasn't going to go very fast with all that stuff hanging out in the breeze, with or without a rear gunner.

AS I keep saying, if the defending fighters can get the "attackers" to drop their external weapons short of the target they have done their job and can go home without firing a shot.
The intended target/s are safe from bombs, rockets and torpedoes. The "self defending" attack plane is as big a myth as the self defending bomber. The ability to self defend only comes into play on the way back, not to the target.

Theory and practice was to fold down the 'turtledeck', so the gunner has a resonably clear field of fire. Check out the picture: link
 
I think all of these positions were somewhat similar. The guns themselves technically had large fields of fire but in practice employment was quite limited because eventually positioning / slipstream gets very awkward for the gunner.

The Barracuda had a Preston-Green mounting for the twin Vickers-K guns (pictured). This was supposed to be just an interim measure while the Rose Brothers developed a twin-Browning continuous feed setup. Testing was basically wrapped up in early 1944 but it doesn't seem to have been put into service at all.

Judging by a lot of official correspondence dealing with the Barracuda -- weight was an issue that was constantly obsessed about. My guess is the superior Browning mounting was left out for this reason.
 
Wow! never knew the Helldiver rear section folded down. I do like the different ways each country cobbled together guns to make duals etc. Although they were probably never more than deterrent or "vengence" weapon to a determined attacker there are quite a few references that when in tight formation the combined fire of light bombers did stop fighters from attacking closely!

Italian aviation did develop a typical late 1930's light attack bomber that they used in combat pre-ww2, the Breda Ba.65 using the typical Fiat 1000hp radial. They ended their service life in 1939-41 north african desert war vs British where they were too vulnerable to Hawker Hurricanes and Tomahawk P-40's.

After the "Fairey Battle experience" Britain seems to have been the first nation to drop the idea of land based light attack planes, to be replaced by fighter-bombers and medium bombers. (Apart from the Vultee Vengance which seems to have been ordered in desperation and was slow in arriving, in Australia we ordered VV's in 1941 and finally received our ordered 400 in early 1944! there was a political scandal about the cost of getting those planes that were obsolete).
 
The RN carrier bombers are ugly and slow but very interesting! The harsh North Atlantic conditions may be a reason they were so conservative in design, they did change to USN planes as soon as the had the chance.

The Fairey Barracuda must be a contender for the ugliest plane of the war, but was their only WW2 carrier bomber that got anywhere near world standards. How the heck was the main wing attached! Also no proper rear gunner station.

The Avenger is one of my favorite planes and was a great design for carrier light bomber, torpedo and long range recon. But infamously in their first fight at Midway 5/6 got shot down and the 6th was a right-off. Maybe the armour was not as heavy on the TBF-1 as TBM-3, but Japanese fighters guns had improved by 1945 also.

P.S. the lead plane is an Australian made Harvard/Texan trainer but with ~600hp engine and 2x0.3 cowl guns, famous as army front line observation/light bomber/supply drop plane in New Guinea campaign.
Off topic here. When did the US Army operate the T-28 ?
 
Heres an interesting article I found about the "4th" crew man that wasn't used in TBF Avenger,

The Mystery of the Middle Seat - Pearl Harbor Aviation Museum

The British did seem to use the extra 4th man in their Avengers. Or maybe the radioman decided to sit upstairs rather than in his "cave" below.

The Swordfish, Devastator and B5N torpedo bombers had 3 crewmen, considering they were rather underpowered I was surprised they could not have had a combined rear gunner/radio man task.

The Swordfish, would delete one crew member when using the auxiliary internal fuel tank.
