Aircraft guns
Starting with the German BK-5 50mm cannon
The BK-5 was an adaptation of a tank gun and was intended primarily for use against Allied heavy bombers. Its magazine held 22 rounds, and the gun had a rate of 45 rounds per minute. BK-5 cannon were installed in some Me 410 twin-engine interceptors and experimentally in the Me 262 fighter, but the war ended before testing with the latter aircraft could be completed. Only about 300 of the guns were produced and combat usage was limited. When Reich Marshal Hermann Goering was captured and questioned on May 10, 1945, he mentioned the BK-5 experiments translated as follows:

"You might find around Germany some jet airplanes equipped with anti-tank guns. Don't blame me for such monstrosities. This was done on the explicit orders of the Fuehrer. Hitler knew nothing about the air. He may have known about the Army or Navy, but absolutely nothing about the air. He even considered the Me-262 to be a bomber and he insisted it should be called a bomber." http://www.nationalmuseum.af.mil/Visit/MuseumExhibits/FactSheets/Display/tabid/509/Article/196225/german-bk-5-50mm-cannon.aspx

Big, automatic anti-tank guns like these may be derided as needlessly complicated and heavy jam-prone weapons unsuited for aircraft that can instead carry rockets, but these big guns are fascinating.

The Beechcraft XA-38 Grizzly was an American 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 Boeing 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. https://en.wikipedia.org/wiki/Beechcraft_XA-38_Grizzly

Beech Aircraft Company XA-38 Grizzly
In March 1942, the Beech Aircraft Company began design work on a two-seat heavy fighter to destroy enemy bombers. Since the Curtiss XP-71 had already been delegated this task, the Beech design evolved into an attack aircraft to replace the Douglas A-20 Havoc. Beech gave this aircraft the in-house designation Model 28 and submitted its proposal to the US Army Air Force on 23 September 1942. On 2 December 1942, the AAF ordered two prototypes and designated the aircraft XA-38; this was Beech’s first combat aircraft. Beech originally called the aircraft Destroyer, but the AAF changed the name to Grizzly. The XA-38 was similar in appearance to the Beech 18, but it was an all-new aircraft. The project was led by Bill Cassidy, and the aircraft was to be strong, maneuverable, and well-armed. Its mission was to destroy fortified gun emplacements, armored vehicles, tanks, submarines, and coastal surface vessels.

The XA-38 was a two-place, mid-wing aircraft with a slim fuselage and twin tails. The gunner sat in the rear of the fuselage and operated remote upper and lower turrets, each fitted with two Browning .50 cal guns. The ventral turret could be locked in the forward position and fired by the pilot in strafing attacks. In the nose of the aircraft were another two Browning .50 cal guns and a T15E1 (M10) 75 mm cannon. The nose swung open to service the guns and was even removable so that different armament could be used. The .50 cal guns each had 500 rounds, and the 75 mm cannon had 20 rounds. Each wing supported two hard points that could carry a combined total of 2,650 lb (1,200 kg) of ordinance or 600 gal (2,270 L) of fuel. https://oldmachinepress.com/2013/05/12/beech-aircraft-company-xa-38-grizzly/

The T15E1 75 mm cannon had an 84 in (2.13 m) barrel that extended about 2 ft (.61 m) beyond the aircraft’s nose. The cannon was self-loading, 144 in (3.66 m) long, and originally weighed 1,800 lb (816 kg). However, through further development, the weight was reduced to 1,138 lb (516 kg). It fired a 26 in (.66 m) shell with a 15 lb (6.8 kg) projectile. The cannon consisted of a 75 mm gun (T9E2), 75 mm feed mechanism (T13), and the 75 mm gun mount (T15E1).

The Grizzly’s aluminum skin was entirely flush riveted, and the fully retractable gear, including tailwheel, was engineered for operations out of unimproved airstrips. The aircraft was powered by two Wright R-3350-43 engines producing 2,300 hp (1,715 kW) each. Each engine turned a 14.2 ft (4.32 m), three-blade Hamilton Standard propeller. The XA-38 could carry 640 gal (2,423 L) of fuel in its wings and an additional 185 gal (700 L) in the fuselage behind the pilot. The aircraft had a wingspan of 67.3 ft (20.5 m) and was 51.8 ft (15.8 m) long. It weighed 22,480 lb (10,197 kg) empty and had a maximum takeoff weight of 35,265 lb (15,995 kg). The XA-38’s climb rate was 2,170 fpm (661 m/m), and it had a service ceiling of 27,800 ft (8,475 m). Maximum speed at 3,100 ft (945 m) was 376 mph (605 km/h), and cruise speed at 16,000 ft (4,877 m) was 344 mph (554 km/h). The 45-degree flaps allowed the aircraft to land at 97 mph and operate out of a 2,500 ft (762 m) runway.

The aircraft program was met with long delays due to the unavailability of the R-3350 engines, remote turrets, and the 75 mm cannon. The Boeing B-29 had engine priority; the Douglas A-26 had the turrets; and the cannon was still being developed. The first XA-38 (serial no 43-14406) took to the air on 7 May 1944 with Vern Carstens at the controls. The turrets were still not available, so dummy turrets were substituted. In July 1944, the aircraft was flown to Tulsa, Oklahoma, where the 75 mm cannon was fitted and ground fired. Later in July, the Grizzly fired the cannon in-flight over Great Bend, Kansas.

Flight tests continued and minor issues were worked out. The aircraft performed very well, and during one early, low-level test flight, the XA-38 was able to pull away from the P-51B chase plane. Capt. Jack Williams evaluated the aircraft for the AAF and made 38 flights in the XA-38 between 13-24 October 1944. The aircraft was reported to be very maneuverable for an aircraft of its size and easy to fly through most aerobatic maneuvers. The aircraft was transferred to Dayton, Ohio for further evaluation on 7 July 1945. At some point, at least a mockup of the upper turret was added to the aircraft.

The second aircraft (serial no 43-11407) took to the air on 22 September 1945; Carstens was again at the controls. This aircraft had the correct turrets installed, and all weapons were operational. After initial flight tests, the XA-38 was transferred to Eglin Field, Florida for armament trials. Here, it amassed an additional 38 hours of flight tests, but there was little interest since the war was over.

The Grizzly’s main problem was that its engines were needed elsewhere. B-29 production left no spare R-3350s available for any type of A-38 production until mid-1945. By that time, the war was winding down, and there was no foreseeable need for the A-38. One of the XA-38s reportedly went to Davis-Monthan AFB, Arizona, but its ultimate fate is not recorded. The other aircraft was believed to be scrapped. The only remnant of the XA-38 Grizzly is the T15E1 cannon on display at the United States Air Force Armament Museum in Eglin AFB, Florida.

To arm the A-38 was the new-designed T15E1 (M10) 75 mm cannon. It was designed to enable the A-38 to destroy enemy bunkers, tanks, and positions with just a single shot, while it also placed random surface ships and submarines on the menu. The gun, in essence, could assassinate a building or destroy a destroyer if given the opportunity.

Air cooled with an 84-inch long barrel, the gun was huge, being 12-feet long from end to end when fully assembled. However, it was extensively stripped of excess material, making it 'just' 406-pounds in weight, which is pretty light for a 75mm cannon. Semi-auto, it could fire a 15-pound, 26-inch long shell every two seconds. These rounds, fired at 2030 fps, could penetrate nearly four-inches of steel armor.

With the gun, mount, and 20-round magazine installed, the M10 tipped the scales at 1063-pounds (just over a half ton). On the bright side, the A-38 got almost 15-pounds lighter every time the gun fired. Watch out for falling brass from this bad boy. http://www.gunownersofcanada.ca/showthread.php?17661-Forerunner-of-the-A-10-Tank-Killer&s=a6f3984b040d9f544dfd9e7913979d93

The US WW2 B-25 G & H Mitchell attack bombers had up to eight (4 nose & 4 cheek/fuselage) forward .50cal HMGs and a 75mm gun.
XB-25G - Modified B-25C in which the transparent nose was replaced to create a short nosed gunship carrying two fixed .50 in (12.7 mm) machine guns and a 75 mm (2.95 in) M4 cannon, then the largest weapon ever carried on an American bomber. (Number made: 1, converted.)

B-25G - The B-25G followed the success of the prototype XB-25G and production was a continuation of the NA96. The production model featured increased armor and a greater fuel supply than the XB-25G. One B-25G was passed to the British, who gave it the name Mitchell II that had been used for the B-25C. The USSR also tested the G. (Number made: 463; 5 converted Cs; 58 modified Cs; 400 production.)

B-25H - An improved version of the B-25G. This version relocated the manned dorsal turret to a more forward location on the fuselage just aft of the flight deck. It also featured two additional fixed .50 in (12.7 mm) machine guns in the nose and in the H-5 onward, four in fuselage-mounted pods. the T13E1 light weight cannon replaced the heavy M4 cannon 75 mm (2.95 in). Single controls from factory with navigator in right seat. (Number made: 1000; two airworthy as of 2015) https://en.wikipedia.org/wiki/North_American_B-25_Mitchell

In anti-shipping operations, the AAF had urgent need for hard-hitting aircraft, and North American responded with the B-25G. In this series the transparent nose and bombardier/navigator position was changed for a shorter, hatched nose with two fixed .50 in (12.7 mm) machine guns and a 75 mm (2.95 in) M4 cannon, one of the largest weapons fitted to an aircraft, similar to the experimental British 57 mm gun-armed Mosquito Mk. XVIII and the German Ju 88P heavy cannon (up to a 75 mm long-barrel Bordkanone BK 7,5). The shorter nose placed the cannon breech behind the pilot where it could be manually loaded and serviced by the navigator; his crew station was moved to just behind the pilot. The navigator signalled the pilot when the gun was ready and the pilot fired the weapon using a button on his control wheel.

The RAF, USN and USSR each conducted trials with this series but none adopted it. The G series comprised one prototype, five pre-production C conversions, 58 C series modifications and 400 production aircraft for a total of 464 B-25G. In its final version, the G-12, an interim armament modification, eliminated the lower Bendix turret and added a starboard dual gun pack, waist guns and a canopy for the tail gunner to improve the view when firing the single tail gun. In April 1945 the air depots in Hawaii refurbished about two dozen of these and included the eight gun nose and rocket launchers in the upgrade.

The B-25H series continued the development of the gunship concept. NAA Inglewood produced 1000. The H had even more firepower. Most replaced the M4 gun with the lighter T13E1, designed specifically for the aircraft but 20-odd H-1 block aircraft completed by the Republic Aviation modification center at Evansville had the M4 and two machine gun nose armament. The 75 mm (2.95 in) gun fired at a muzzle velocity of 2,362 ft/s (720 m/s). Due to its low rate of fire (about four rounds could be fired in a single strafing run), relative ineffectiveness against ground targets, and the substantial recoil, the 75 mm gun was sometimes removed from both G and H models and replaced with two additional .50 in (12.7 mm) machine guns as a field modification. In the new FEAF these were re-designated the G1 and H1 series respectively.

The H series normally came from the factory mounting four fixed, forward-firing .50 (12.7 mm) machine guns in the nose; four more fixed guns in forward-firing, individual gun packages; two more in the manned dorsal turret, re-located forward to a position just behind the cockpit; one each in a pair of new waist positions, introduced simultaneously with the forward-relocated dorsal turret; and lastly, a pair of guns in a new tail gunner's position. Company promotional material bragged that the B-25H could "bring to bear 10 machine guns coming and four going, in addition to the 75 mm cannon, eight rockets and 3,000 lb (1,360 kg) of bombs."

The H had a modified cockpit with single flight controls operated by pilot. The co-pilot's station and controls were deleted, and instead had a smaller seat used by the navigator/cannoneer, The radio operator crew position was aft the bomb bay with access to the waist guns. Factory production total were 405 B-25Gs and 1,000 B-25Hs, with 248 of the latter being used by the Navy as PBJ-1H. Elimination of the co-pilot saved weight, moving the dorsal turret forward counterbalanced in part the waist guns and the manned rear turret.

Stukas equipped with twin 37mm cannon for tank busting operations on the Russian front.
Both tank killing variants featured a twin MG 81Z 7.92mm machine manned by the radio operator and two Bordkanone BK 3,7 37mm cannons on the wing stations. The cannons were mounted in streamlined pods which hpoused the firing chamber, recoil damper, electro-pneumatic charging mechanism and an electrically powered trigger assembly. The ammunition was fed from two box magazines holding two frames of six rounds each. The magazine was placed on the the right hand side of the cannon. Spent shells were ejected through an opening on the opposite side of the weapon. After the last round had been fired, the lock would remain in the open position, which in turn triggered illumination of a cockpit annunciator on an SZKK 2 (Schußzahl-Kontrolltaste 2) ammunition counter.
The most commonly used ammunition was armor-piercing (Panzergranate) type. Each cartridge weighed 1,460g including a 623g bullet. New M and L types of armour-piercing ammunition were introduced in 1944. The L type bullet was 124.5mm long and featured a tungsten core which gave it a capability to penetrate a 120mm armor plate, provided it was not angled at less than 60 degrees.

...In total, 20 Ju87G-1s and 210 Ju87G-2s were manufactured.

> You might find around Germany some jet airplanes equipped with anti-tank guns. Don't blame me for such monstrosities.

That's hilarious.

War is Boring just had an article about Columbia's re-engined upgraded AC-47s. The "T" model uses PT6 turboprops instead of the radial engines, a good call, and infrared imaging to find motherhumpers in the jungle to blast to hell.

The Westland Whirlwind was a British twin-engined heavy fighter developed by Westland Aircraft. A contemporary of the Supermarine Spitfire and Hawker Hurricane, it was the Royal Air Force's first single-seat, twin-engined, cannon-armed fighter.

When it first flew in 1938, the Whirlwind was one of the fastest and most heavily-armed combat aircraft in the world. Protracted development problems with its Rolls-Royce Peregrine engines delayed the project and only a relatively small number of Whirlwinds were built. During the Second World War, only three RAF squadrons were equipped with the Whirlwind, and despite its successful use as a fighter and ground attack aircraft it was withdrawn from service in 1943. https://en.wikipedia.org/wiki/Westland_Whirlwind_(fighter)
