Per request. Two good looking airplanes (IMHO)

Beechcraft XA-38 Grizzly

Per Wiki:

The Beechcraft XA-38 Grizzly was a United States ground attack aircraft, fitted with a forward-firing 75 mm cannon to attack heavily armored targets. The first prototype flew on 7 May 1944 but after testing it became obvious it would not be ready for the projected invasion of Japan, and furthermore it used engines required by the B-29 Superfortress — which had priority - and so it was canceled after two prototypes had been completed.

The United States Army Air Forces awarded the Beech Aircraft Corporation a contract in December 1942 for two prototypes for their Model 28 "Destroyer". The requirement was for a powerful ground attack aircraft to replace the Douglas A-20 Havoc, with the ability to hit "hardened" targets like tanks and bunkers. This capability was achieved through a 75 mm cannon with 20 rounds, mounted in a fixed position on the nose as well as two .50 cal (12.7 mm) M2 Browning machine guns firing forward. Defensive armament consisted of remotely-controlled ventral and dorsal turrets, each armed with twin .50 cal (12.7 mm) machine guns. There were to be two crew members, a pilot and an observer/gunner in the rear cabin, using periscope sights to aim the guns.


On 7 May 1944, Beech test pilot Vern Carstens flew the XA-38 on its maiden flight from the company's Wichita airfield. The aircraft proved satisfactory in all respects and better than expected in some, including top speed.

During testing, the XA-38 prototypes were flown by U.S. Army pilots and serviced by military personnel, proving to be reliable and establishing a high level of serviceability.

The armament proved especially effective and had it not been for wartime priorities shifting in 1944, the aircraft would most likely have been ordered in quantity[citation needed], although the B-29 had priority for the Wright R-3350 engines. Instead, one prototype was scrapped and the other, intended for the USAF Museum, had an unknown fate.

Douglas XSB2D-1 & BTD Destroyer

Per Wiki:

On 20 June 1941, the United States Navy placed an order with the Douglas Aircraft Company for two prototypes of a new two-seat dive bomber to replace both the Douglas SBD Dauntless and the new Curtiss SB2C Helldiver, designated XSB2D-1. The resulting aircraft, designed by a team led by Ed Heinemann, was a large single-engined mid-winged monoplane. It had a laminar flow gull-wing, and unusually for a carrier-based aircraft of the time, a tricycle undercarriage. It was fitted with a bomb bay and underwing racks for up to 4,200 lb (1,900 kg), while defensive armament consisted of two wing-mounted 20 mm (0.79 in) cannon and two remote-controlled turrets, each with two .50 in (12.7 mm) machine guns.[1]

The prototype first flew on 8 April 1943, demonstrating excellent performance, being much faster and carrying nearly double the bombload of the Helldiver, and orders for 358 SB2D-1s quickly followed. The U.S. Navy changed its requirements, however, wanting single-seat carrier-based torpedo/dive bombers without defensive turrets, and Douglas reworked the SB2D by removing the turrets and second crewman, while adding more fuel and armor, producing the BTD-1 Destroyer. The orders for SB2Ds were converted to BTD-1s, with the first BTD flying on 5 March 1944

The first production BTD-1s were completed in June 1944. By the time Japan surrendered in August 1945, only 28 aircraft had been delivered, and production was cancelled, along with other aircraft types that had been designed from the start as single-seaters, such as the Martin AM Mauler.[3] None saw combat action. In any event, Heinemann and his team were already working on developing the single-seat BT2D that became the Douglas A-1 Skyraider.


General characteristics:
Crew: One
Length: 38 ft 7 in (11.76 m)
Wingspan: 45 ft 0 in (13.72 m)
Height: 13 ft 7 in (4.14 m)
Empty weight: 11,561 lb (5,244 kg)
Max. takeoff weight: 19,000 lb (8,618 kg)
Powerplant: 1 × Wright R-3350-14 Cyclone 18 radial engine, 2,300 hp (1,715 kW)

Performance
Maximum speed: 334 mph (290 kn, 538 km/h) at 16,100 ft (4,900 m)
Service ceiling: 23,600 ft (7,195 m)

Armament
2 × 20 mm AN/M2 (.79 in) cannons, 200 RPG
Up to 3,200 lb (1,450 kg) of bombs in the bomb bay or two 1,947 lb Torpedos

Interesting photo montage, especially the head on and tail on shots of the BTD-1 sitting among all those North American products at what appears to Grand Central Air Terminal in Glendale.

More really cool stuff!

Don't make me go get my flying monkeys-

My dad worked at NARF NAS Norfolk for 1959 to 1982 so I got to go down there and play around in a lot of aircraft. The BTD 1 was on the line near the old sea plane ramps in the early 70's. Never knew why it was there or what they did with it. For it to have survived that long I assume it had some use. Anyone know if it still exists ?

Still exists. The sole survivor was recently reported to be going to the Hixson Museum of Flight:

here's a few photos of the survivor.
According to Wiki: BTD-1, BuNo 4959, Wings of Eagles Discovery Center, Elmira-Corning Regional Airport, Elmira, New York. This aircraft had long been in the Florence Air & Missile Museum collection until the museum's closing in 1997

The XA-38 looks like a Twin Beech on some serious steroids. I don't think I'd want to be on the business end of that 75mm!

Does that Douglas XA2D that was in Idaho still exist?

In the next to the last photo, what's the t-tail aircraft in the background?

Elwyn--

Appears to be the Curtiss XF15C "Stingaree"...another USN bird that did not enter service. I vaguely recall that it too was in a museum collection at some point. NEAM, maybe?

I'm guessing the Curtiss XF15C jet/prop hybrid.

http://en.wikipedia.org/wiki/Curtiss_XF15C

Apparently it still exists, and is on display at the Quonset Air Museum in Rhode Island (painted a rather garish "blue angel blue.")

Thanks. I remember having seen photos of it now. Couldn't have pulled up the name from memory in a hundred years though.

Mark, thanks for posting another of your amazing photo threads.

While I was aware of it, I never truly understood how beautiful of an aircraft the BTD-1 was!
