Swedish Antiaircraft Artillery: Bofors 40mm Automatic Gun M1

[@joshuapowell2675]

One of these hangs out of the AC-130U. It basically acts like anti-vehicular sniper rifle because it's so accurate. Really cool memory: we had to swap out a feeding mechanism while we were in Afghanistan and the body was stamped with the year "1942". Easily one of the most reliable weapons ever created

[@Rikard_Nilsson]

It's also still used by the Swedish CV9040 IFV. Mounted upside down to eject the spent casings out the top of the turret.

Royal Thai Navy servicemen here, The Bofors 40/60 are still being used in the Thai Navy. Even though the manual says that the gun is manned by 3 crews, what we usually do is we have one extra guy carrying more ammunitions because not only that these thing can fire faster than you can reload, they also only have 7 rounds capacity and the sergeant on the pedal is often one trigger happy bastard. Oh an fun facts; the 40/60 refers to the 40mm size of the cartridge but the 60 refers to the length of the barrel, as in it is 60 times longer than the diameter

[@MarsFKA]

10:10 "Credited with a couple of V1 rocket bombs." In addition, at least one Me-262 jet fighter. In my early teenage years, I read "Wing Leader", by Johnnie Johnson. the RAF top scoring Spitfire pilot in Europe. In it, he told how he landed, in his brand-new Mark XIV Spitfire, at a forward airfield in Holland, just in time for a strafing run by a Me-262. Johnson hit the deck and watched the 262 disintegrate - an airfield defence Bofors crew happened to have their gun pointed in just the right direction as the jet flew away from the airfield, fired one clip of four shots and blew it to bits.

Now, 100 divided by 4 is 25, so the test only took 25 seconds, but I must say, that those 25s were a looong 25s. It "just kept going". "Will it not end?" Impressive.

When i did my mandatory military training back in the eighties.(Sweden) I were in an artillery observer/fire control role. Ofc this were on the updated version called 40/48, 4 shells per second. One time we had to dig trenches around the gun to defend it. I ended up in a trench some 4-5 meters from the muzzle. When the gun crew started firing, that thing pushed the air out of my lungs and with every shot i had less air left. The gun crew didnt stop firing until they expended something like 30-40 rounds. (We had two loaders so they could really put clips in fast.) When they finally stopped firing i was gasping for air. An awesome experience that will stay with me for the rest of my life. What a powerful gun!

[@CAwolfguy]

The Bofors L70 cannons were an integral part of the Sgt. York (M41) AA gun system. I worked on the Sgt. York project through the early 80s. I remember in changing out barrels that each weighed at about 365 lbs. The twin cannons were part of an ammo feed system that allowed the fire unit to fire 10 rounds/second.

[@Perfusionist01]

Thanks for showing us this Ian. It really is an iconic gun from WW2. The US even built motorized mounts, usually on tank chassis. One such, the M19, was built on the chassis of the M24 light tank and was used for ground fire in Korea. The M42 used on the chassis of the M41 light tank and was used for ground fire in Viet Nam. In that conflict iit was usually nicknamed "Duster". After Viet Nam the Army was in the process of discarding the Dusters when somebody realized that 1) the attack helicopter had become a real danger on the battlefield and 2) we no longer had mid-range AA weapons that would destroy or deter an attack helicopter. The remaining M42s in the National Guard received a short lease on life, but finally retired. Bottom line is that the original Bofors design stayed in US service until the early 1980s!

Although Bofors don't make the guns anymore, the Italian defence contractor Leonardo produce a version of it as the OTO Marlin which is a fully integrated and fully automatic (100 or 300rpm) naval gun turret which incorporates an angular stealth design and its own gun director with optical/IR cameras and a laser rangefinger. Lethality is even better than it was now that these guns have muzzle velocity radars and can fire smart ammunition which can be set to airburst right over targets even if they're behind cover.

Also, due to jets flying faster and higher, Bofors did experiment with a scaled up version of the gun, the 120 mm LVAkan (Luftvärnsautomatkanon) 4501, which is basically a 40 mm Bofors blown up to 300%, firing 80 RPM. Only ended up being used by the Finnish Navy, Indonesian Navy, - they kept the prototype around for point air defense of the Bofors factory, with the guns chief designer having the wartime role of gun crew chief.

I am from sweden and OH MAN I LOVE THIS GUN

[@Sp1der44]

Also worth noting that splitting the two positions between Traverse and Elevate allowed the traverse Guy to focus on the Lead compensation and the flight time of the projectile to the target while the elevate guy would be doing the same thing but with the projectiles drop relative to shooting at different angles and distances to the target - the way they divided these two complex tasks is very elegant. What a beautiful piece of craftsmanship these things are. My favorite ever is in 1941 when Dan Aykroyd gives the extensive and well explained list of "things to never ever do with your Bofors 40mm Anti-aircraft gun" after dropping one off on the California Coast and giving the civilian to whom it's been entrusted at least 3 minutes on how to "Never, ever, under any circumstances, employ the Gun" - it was Brilliant! : D Great Video Ian! - MM in Denver CO

The gun is used in the swedish spec of the ifv cv90. An awesome gun that will be in service for many years to come!

This gun was very widely used by the British Army in Hong Kong back in the 1950's, it could be fired while being towed and was supposed to be able to hit planes at 40,000 feet (you had to know what you're doing) and was used in Europe by both sides in WW2. The 40mm is a great round.

[@slick_slicers]

Had one of these on our River Class minesweeper HMS Spey in the early 1990’s. Our gun was built in 1943, and originally used by the Royal Artillery. In a curious twist of fate my stepfather was in charge of anti-aircraft bofors guns in the Royal Artillery in 1943 to 45. It could easily have been one of his guns. Interestingly, though the earlier Ton Class Sweepers had powered mounts, our later River Class (HMS Spey) had its original WWII manual mount.

[@solentbum]

When I was four (1952)I picked up the unexploded shell from a Bofors AA gun on the newly opened beach at Calshot (near Southampton) Before I could throw it my father grabbed it from me , and went very white. He handed the shell in at the nearby RAF station. Apparently my father had been trained on the Bofors during his time as an Artilleryman and knew what they could do.

My dad operated the trigger and elevation of a 40mm Bofors from the bow of LSM 46 while beached on Red Beach at Iwo Jima. They were being heavily shelled at the time that they were ordered to put some rounds into a few of the Japanese positions on Mount Suribachi. Quite effective at that short range. Thanks for the great video!

I'm Swedish and i live 10 minutes away from a V1 missile.

[@thatguy3428]

I remember reading years ago these were heavily used to defend Antwerp once the Allies liberated the city. Antwerp was an important forward port in the advance so the Germans did everything they could to disrupt it once they lost it. V1 and V2 strikes were a constant occurrence. The volume of AA ammunition needed to defend Antwerp severely interrupted the import of other supplies. A V1 was relatively easy to shoot down due to its constant course especially after proximity fuses were introduced, a V2 was impossible to shoot down once it left the pad. At one point, a plan was created to use radar to predict a "box" where a V2 would pass and use many Bofors with timed fuses to saturate the box. The reason it was never implemented is the V2 was already on a ballistic trajectory and there was no guarantee the warhead would be destroyed unlike a V1 which could be shot down before being close to the city. Secondly, considering the shear number of 40mm shells needed for an effective kill box and the rate of duds, there would've been more total explosive ordinance raining down from the 40mm than from the V2 itself. I still have the 1944 dated Bofors stripper clip that my dad got for me. Interesting piece of history.

[@fredrikcarlen3212]

These are still used in the Swedish CV9040 IFV, I remember burst firing this thing was cooler than the 120mm main gun on my tank! Something so cool about it ejecting the casings 100ft in the air!

[@johnsalt1157]

Antwerp-X, the air defence of Antwerp against V-1s, was based entirely on anti-aircraft artillery, and was the most effective air defence campaign in history, knocking down something like 98% of the attackers.

[@peterodonnell5820]

I was a radar instructor in the British Army in the '70s and I trained British and Malaysian technicians on an anti-aircraft system using a powered, and armour plated, 40mm Bofors coupled to an EMI fire control radar which used a mechanical computer for auto-tracking. The right hand radar operator (of two) had a foot trigger to fire the gun and a coarse/fine synchro servo system made the gun follow the radar. The radar used the same wheeled chassis as the gun and both were driven by hydraulic swash plate mechanisms giving a fast rotation speed. The gun still had the two seats with the hand cranks (and you're right, they are really cool!), and there were two waisthigh rings for two loaders to stand alternately slamming clips into the breech. There were also two racks of 'one way' clips so loaders behind the gun could fill clips and push them into the racks for the loaders.

[@MrCarlBackhausen]

We were the last to be trained on this.

[@johnsalt1157]

I have happy memories of firing one of these (on the Mk 9 mount, electrically driven and controlled by a single gunner) as a CCF Navy cadet aged 16 on a gunnery course at HMS Excellent (then the RN gunnery school). We fired breakup shot, lead balls in a bakelite case, which had a danger area 120 degrees each side of the muzzle for about 50 metres. The cadet loading the thing would get the occasional lead shot pinging off his steel helmet, and there must have been a fine drizzle of lead shot and bakelite fragments falling on the nudist beach below the cliff the battery was sited on.

[@sarjim4381]

The US Navy developed the Mark 57 Gunfire Control System late in the war. It wasn't really a better optical control system than the original Mark 51 director, but it added radar for use in reduced visibility conditions. One Mark 57 then controlled four Mark 51 directors. The Mark 51's were still useful in good visibility, but any massed gunfire lasting more than a minute or so caused the targets to be obscured by gun smoke. That's when the Mark 57 took over and controlled the four 40 mm quad mounts instead of the four separate Mark 51 directors.

As a child in the mid ‘60s there was a box for a toy in a cupboard that I was always fascinated with. It was a battery operated Pom-Pom gun that belonged to an older brother. I don’t recall ever seeing the toy but the box was around for years storing who knows what inside it. But ever since then Bofors has been high on my WWII list of things to either own or just geek out on. I’ve always loved Bofors cause they bring the pain!

I was a L70 cannon personell in Norway in the 80-s. The L-70 is in many ways like your L-60 , except the L-70 also had hydrostatic electrical powered control position so it could be used by only 1 gunner (plus loaders , putting the clips in) The L-70 also could be operated manually , just like the gun you show here , then with 4 men. (optional 5 with cannon commander on the rear , giving the orders to all included external comm operator) The L-70 could also be connected for remote control by a radar system , but the personell still had to be on cannon. Remote generator for electricity of course.
