One of the most intriguing aspects of the 155mm construction is the weight reduction - everything that's not necessary is removed, they even made the walls of the equilibrators exactly as thick as they need to be to be sturdy enough for the battlefield, not a millimeter more. Mechanical elegance through omission. I call that beauty. Great video btw.

[@micklenier6152]

I wonder what is considered "not necessary". because honestly almost all modern artillery pieces have onboard electronics (ballistics computer).

My 1965 , 155 HOW was self propelled. It looked much like a tank. It carried a 6 man team inside. The vehicle was powered by two Chrysler V8 engines under carriage. The total weight was 25 tons. The top speed was 50 Mph. I think it had a 30 mile target range..

With some of the pill boxes in WW2’s Siegfried Line the American artillery would drop a 150mm shell on the roof, shortly after the Germans would come out holding their heads.

[@felixthecat265]

An excellent explanation, however a couple of minor points. 1. Your explanation of the recoil distance being reduced to stop the breech hitting the ground at high elevation gets the issue the wrong way round.. The problem is with recoil at low elevations where the recoil is trying to push the carriage back across the ground. To allow the use of a relatively light carriage, you need to let the barrel recoil a considerable distance at low elevations to spread the shock over a longer period and reduce the peak loading of the carriage. At high elevation most of the shock goes down into the ground and you do not need the barrel to recoil so much as well as there being less space for the breech to move. 2. Equilibrators are needed if the trunnions are not at the centre of gravity. Most guns with limited elevation keep the trunnions forward at the centre of mass, or use barrel weights to balance the barrel. In high elevation guns it is better to have the trunnions to the rear as it reduces the swing of the breech. You could use breech weights as well, but they add to the carriage weight and really only have been used on anti aircraft guns such as the WW2 UK 3.5" AA gun. The old US M1 105 and the British 25pdr had balanced trunnions.

[@donblevins1181]

What makes it a howitzer is the breach. I was F.D.C. station with a 8 inch artillery battalion. in my training all were referred to as guns except morters. Mortar's do not have rifling or a breach. A howitzer has an angle of fire from 0 degree's to about 48 degree's

[@starblazer6907]

all this fancy high tech innovations and its still set off with a good old fashioned string

[@bob_the_bomb4508]

The key point about a modern mortar is that it transfers the recoil into the ground via its base plate. This means that you don’t need the recuperators and recoil mechanism which reduces the weight, which allows medium mortars to be broken down and be ‘man portable’

Best video ever I've seen about how artillery works! Well done!

[@billmacrae1924]

Great video except for the loud distracting music. My question is not part of the material of this video, but it is interesting all the same. A shell fired from a high angle howitzer is spinning due to the rifling. The spin causes the shell to keep pointing in the same direction. What then causes it to change orientation during the trajectory so that it hits the ground nose first? Or does it hit the ground tail first?

[@milantrcka121]

Alas, this channel is not the only one with this super annoying and totally unnecessary background noise. If it really must be there, reduce the volume by at least 6 dB! Even more baffling is why it "must" be there in the first place.

[@bmitch3020]

If I were to guess, aerodynamic drag, which would act more on the base of the shell than the pointed tip. The spinning minimizes the effects of air resistance, to prevent tumbling, but not all of it.

[@christianwouters6764]

Interesting to see that the recoil mechanism is the same as more than 120 years ago.

I loved the 198 HOW; it was devastating firepower and fun to fire and watch rounds coming in. Thank you for the video!

Excellent material. May be you could do a video explaining the basics of arming, aiming and firing of these howitzers. When I make models, I'm always fascinated with the red and white striped stick attached to the trail of the gun. I think it's meant to assist with aiming of gun, but I don't know how.

[@slimjimnyc270]

I think they are either aiming posts or surveying sticks. Since artillery is a non-line-of-sight weapon, you have to know where the howitzer is located and where it is pointing. You locate a aiming posts away from your weapon and use it a reference point for direction and distance. For example, you place the posts 30 meters away, 45 degree to the right and left of your gun tube. Your cannon is now pointed toward your target. After firing a few rounds, your whole howitzer moves from the recoil and now the tube is actually pointing 43 degrees to the right and 47 degrees to the left of the posts. You look thru the aiming device to see the posts and move the cannon until it 45 degrees left & right of the aiming posts. You are now back on target and keep on firing. It is a little bit more complicated than that but I hope you get the basic idea.

[@g43654]

@@slimjimnyc270 thanks. That makes sense. I think they can also check gun elevation with these sticks as well, right?

[@slimjimnyc270]

@@g43654 I seem to remember that it can use to check elevation.

[@doughudgens9275]

@@g43654 no. Aiming stakes are for direction only. They are the fallback for firing azimuth. The primary is the scope on a tripod located to the left front of the piece. It looks like a 1.5’x3” tube and is called a collimater. The gunners sight on the piece has elevation scales, and often the right side has an elevation only sight. Finally, there is a gunners quadrant to final check elevation. Think protractor with a level. I’m not going to get into the details of “laying a Battery”- that’s a long video in of itself. This is old school, non GPS aiming.

The 155mm howitzer shown in this video is what we in the Marine Corps called the "Pig". But they did not have a muzzle brakes on them. They were a pain in the ass to setup due to the very heavy square plate used to support the howitzer when the wheels were lifted into the firing position..

When in high angle how those shells and propellant did not sliding down even though it's breechloader not closed yet?

[@doughudgens9275]

When you ram the shell into the chamber, the brass ring engages in the rifling and removal backwards is difficult. This explains why the shell doesn’t fall out. The powder is in a cloth bag, so if you use your fist when shoving it into the breach, it will slightly squish in the middle and expand outwards gripping the chamber walls long enough for you to remove your hand and close the breach.

[@loganteodoro2885]

That's a great question. This video doesn't cover that. Aiming is somewhat complicated but could probably be explained with the video like this. There are ways to do it with digital systems and sensors as well as with optical systems. I think The optical way we do it is probably still the same way we used to do in world war II. It's a system of scopes, levels, and math. Unfortunately it would take a little too long for me to explain it in a KZbin comment. By the way, the way you explained how it will bounce and misalign the barrel each time is something called displacement

[@jeffsiegwart]

Nice Job!

[@csjrogerson2377]

Easy: Same as 203mm, 105mm and any other piece of artillery. Point gun at the enemy. Insert shell in the big end (the breech). Pull rope. A loud bang with smoke and flame and shell will come out of the other end (the barrel). Repeat. After 10 reps, have a cup of tea. Please ensure you wear your ear defenders and keep the barrel pointing in a safe direct at all times. Well safe for you, not so much the enemy. There we go, easy. Artillery 101.
