Mnogi su osporavali njegovu klasifikaciju u avionske topove zbog male početne brzine. Bio je inspiracija za neke potonje bacače granata bez čaure. Japanski Ho 301 40mm

Imao je samo 150 metara efektivnog dometa. Inspiracija je bio prvenstveno za ruske bacaće granata.

RJ ::F-4E zvani "Chico the Gunfighter" naoružan sa 4 kontejnera SUU-23 sa šestocevnim topom M-61 Vulcan

Deluje "moćno", ali samo deluje...

Težina punog SUU-23: 1730 lbs=785 kg? Pa, puta 4 + centralni podtrupni (ima nešto ne vidi se najbolje, možda čak još jedan SUU-23)+ rakete.
Phantom F-4E:
EMPTY WEIGHT: 30,328 lb (13,757 kg);
MAX.LANDING WEIGHT=36,831 lb (16,706 kg)

Što će reći, ovako naoružan "Chico the Gunfighter" je pre Chico, Zagorov frend

I SUU-23 su bili sa GAU-4, unapređenom verzijom

Nešto iz biroa Makarova za odbačenu familiju lovaca Je-150
Citat:News has emerged of two experimental Russian aircraft guns dating from the 1950s or 1960s, both designed by Makarov whose name is now associated with the standard Russian Army pistol.
The Makarov TKB 539 was a 30mm 4-chamber revolver cannon, with an unusual action in which the cylinder was allowed to recoil via the gas system action in order to unlock from the barrel, rotate 90 degrees and then relock. Obturation was achieved by inserting the case neck into the barrel for about 25mm. The cylinder was loaded from the front with special cartridges having a reduced-diameter head (a similar arrangement to the R-23). Fired cases were ejected from the front using gas pressure from the next shot. The gun weighed 73 kg (the feed system another 16.8 kg), was 184.5 cm long and fired at 2,000 rpm. The ammunition generated a muzzle velocity of 1,000 m/s.
The Makarov TKB 532 was a 23mm gun using an entirely different mechanism. It is unclear from the description whether the breech was unlocked by recoil or gas, but ejection of the fired case was purely due to blowback (no extractor or ejector fitted) with fresh rounds being catapulted into the breech by a short-stroke spring-loaded rammer. The breech was also unusual, consisting of two sideways-sliding elements like dual sliding doors.

This cartridge was developed during WW2 for the Japanese Army air force's Ho-5 cannon, also known as the 20mm Type 2. The gun was based on a slightly enlarged Browning M2. As designed, it offered an impressive combination of high performance and light weight, but the lack of high-quality steels for gun-making meant that the ammunition had to be significantly downloaded to reduce the stress on the gun mechanism. Despite this, the Ho-5 was the Army's standard aircraft cannon at the end of WW2
