Nope . I used to work on the 51 & 81mm mortars for the royal Ordnance in nottingham
The method is a simple firing pin at bottom of tube drop shell in hits firing pin which is permanently fixed in bottom of tube Pooof off it goes and lands in general region of aimed
Its the reverse of a bullet which sits still and a moving firing pin strikes it
Can be EXTREMELY accurate .

When I was about 7 I lived in Zimbabwe and at the time it was Rhosdaisa(fuck it been so long cannot remmeber how to spell it)
we lived in a house about 1 km from the main police station and once the terrists did a mortar attack from the field behind our house at the police station.
The noise was mad we were hinding under the beds.
anyway we were pissing about in the drains tunnels about two weeks later and found about 4 mortars.
showed them to my brother-in-law he fucking shit him self and said if you find anymore don't touch them.
they have a firing pin at the bottom.

The casing is what held the charge to push the bullet out when it goes bang etc
Thus leaving the casing which was simply the packaging of a bullet
teh best way to describe a mortar albeit crudely is
A locally fired rocket
The mortar casing carrys both the proppleant which launches it into the sky like a rocket the casing here is the rocket body with fins to stabalise in flight
The warhead is also at the tip of the casing which has its own internal firing pin to make it get noisy upon impact with something firm

Correct . The projectile of a bullet is the end bit (tip) which leaves the barrel
The casing is what held the charge to push the bullet out when it goes bang etc

but lol how is the charge fired? As surely something has to give to set the charge off. If you see what i'm getting at?

Also be aware that these are the preffered weapon of many terroist groups against personel due to the distance these things can fly

Does a missile leave anything behind or make a bang ??? No
The reason being is that the initial propellant is a controlled explosing venting through a small exhaust thus creating thrust which lifts the mortar into the air
The bang is the HE charge going off upon landing which is an uncontrolled detonation ie fucking quick bang

Too many posts.. I need a life!!
For fuck's sake, what's so hard to get your head around???
The spaceshuttle doesn't 'leave anything behind', nor does your average fireworks rocket.
As Nige explained, very clearly might I add, the shell contains both propellant and warhead.
The shell is nothing more than a stabilized tube filled with a fuel and a warhead on top.
When the fuel ignites (by means of the fixed firing pin) it burns so rapidly that it propelles the shell out of the mortar tube.

mrjenrst the impact of dropping the mortar in the tube is enough to detonate the firing charge. its not rocket science. erm ok it is
You will find with most munitions a small charge sets off the bigger main charge, be it a warhead or a propellant. All it takes is a small amount of impact sensitive explosive and a impact to set it off.
Its really not that complicated.
If you can understand that a toy cap gun, the impact of the hammer sets off the bang then you can understand how most munitions and explosives work.

are they a completly sealed unit that has to be armed before use. Ie removing something first? Or is it just a drop in and go? I understand most ballistic's its just the physical firing of the pin to the actual charge going off i'm struggleing with

I see what the op is saying ,
if you hold a mortar up , the end that the firing pin strikes must be sealed to stop the propellant falling out yes ?
so if its a sealed unit , how does the propellant erm .... propell , without leaving either a sealing cap or something behind ?
Probably not a good idea to start googling this subject either, unless you want your i,p to be flagged for security checks .

ok then imagine how a shot gun cartridge which is sealed doesnt just explode in the gun killing the owner!!
Not many pics on line but this is the bottom of a WWII mortar.
In effect all the explosive is burnt and the propellant comes out bottom as its a weak point. You also have a few small holes on sides to get rid of excess flash.
